INGREDIENTS YOU’LL NEED:
To create this comforting and flavorful Easy Spaghetti Squash Casserole, you will need a selection of fresh, high-quality ingredients that work together in perfect harmony. The star of the dish is, of course, the spaghetti squash. Choose a medium-sized spaghetti squash that feels heavy for its size, indicating it is ripe and full of flesh. A good quality spaghetti squash will provide ample strands for the casserole.
For the creamy and cheesy base of the casserole, you will need cream cheese. Full-fat cream cheese provides the richest flavor and creamiest texture, but reduced-fat cream cheese can also be used for a slightly lighter version. Good quality cream cheese is essential for a smooth and luscious sauce.
Milk is another key ingredient for the sauce, adding moisture and helping to create a creamy consistency. Whole milk will provide the richest flavor, but 2% or even nonfat milk can be used to reduce fat content. The milk thins out the cream cheese and creates a pourable sauce.
Shredded cheddar cheese adds a classic cheesy flavor and wonderful melt to the casserole. Sharp cheddar cheese provides a robust flavor that complements the mild squash, but mild or medium cheddar can also be used depending on your preference. Pre-shredded cheddar cheese offers convenience, or you can shred your own from a block.
Grated Parmesan cheese adds a salty, savory, and umami-rich element to the casserole. Freshly grated Parmesan cheese is highly recommended for the best flavor. Avoid pre-grated Parmesan which may not melt as smoothly or have the same depth of flavor. Authentic Parmesan cheese elevates the cheesy flavor profile.
Onion and garlic are the aromatic base of the casserole, providing foundational savory flavors. Yellow onion is recommended for its mild and versatile flavor. Fresh garlic cloves are essential for the most robust garlic taste. These aromatics build a flavorful base for the casserole sauce.
Dried thyme and dried oregano provide classic Italian-inspired herbal notes that complement the cheeses and squash beautifully. These dried herbs add depth and complexity to the flavor profile without overpowering the other ingredients. They create a savory and aromatic seasoning blend.
Salt and freshly ground black pepper are essential for seasoning and enhancing all the flavors in the casserole. Use kosher salt or sea salt for the best flavor. Freshly cracked black pepper provides a more aromatic and nuanced flavor compared to pre-ground pepper. Proper seasoning is crucial for a well-balanced and flavorful casserole.
Optional additions such as chopped fresh parsley or breadcrumbs can be used for garnish and texture. Fresh parsley adds a pop of color and fresh herbaceous aroma. Breadcrumbs, especially panko breadcrumbs, can be sprinkled on top for a crispy topping. These optional garnishes enhance both the visual appeal and textural interest of the finished casserole.
HOW TO MAKE “Easy Spaghetti Squash Casserole”:
Creating this comforting Easy Spaghetti Squash Casserole is a straightforward and rewarding culinary process. The recipe centers around the principle of baking, a method of cooking food in dry oven heat. Baking is perfect for casseroles as it allows for even cooking and melting of cheeses while developing a golden-brown top.
The recipe is structured into clear, easy-to-follow steps. It begins with preparing the spaghetti squash by roasting or microwaving it until tender. While the squash is cooking, a simple creamy cheese sauce is made on the stovetop. Once the squash is cooked and the sauce is ready, they are combined, topped with more cheese, and baked until bubbly and golden brown.
By carefully following the step-by-step instructions, even novice cooks can easily achieve a delicious and satisfying Easy Spaghetti Squash Casserole at home. The simplicity of the method belies the incredible flavor and comforting nature of the finished dish. Get ready to enjoy a healthier and equally satisfying alternative to traditional casseroles.
STEP-BY-STEP INSTRUCTIONS:
Step 1: Prepare the Spaghetti Squash. Preheat your oven to 400°F (200°C). Preheating the oven to the correct temperature is crucial for proper roasting of the spaghetti squash.
Wash the spaghetti squash thoroughly under cold running water. Scrub the squash to remove any dirt or soil from the skin. Clean squash is essential for both hygiene and taste.
Carefully halve the spaghetti squash lengthwise. Use a sharp, sturdy knife to halve the squash. Spaghetti squash can be dense, so be cautious while cutting. Scoop out and discard the seeds and stringy fibers from the center of each half. Removing seeds and fibers prepares the squash for roasting and makes it easier to access the flesh later.
Place the squash halves cut-side down on a baking sheet. Lining the baking sheet with parchment paper can make for easier cleanup, though it’s not strictly necessary. Roast in the preheated oven for 40-50 minutes, or until the squash is tender and easily pierced with a fork. Roasting time will depend on the size of the squash. Check for doneness by testing for tenderness with a fork.
Alternatively, you can microwave the spaghetti squash for faster cooking. To microwave, pierce the squash several times with a fork. Microwave on high for about 10-15 minutes, turning halfway through, until the squash is tender. Microwaving is a quicker method but may not yield the same roasted flavor as oven roasting. Let the cooked squash cool slightly before handling.
Once the squash is cool enough to handle, use a fork to scrape out the spaghetti-like strands from the inside of each half. The cooked squash flesh should easily separate into strands resembling spaghetti. Collect the spaghetti squash strands in a bowl. Set aside.
Step 2: Sauté Onion and Garlic. While the squash is roasting or microwaving, prepare the onion and garlic base for the sauce. Dice the yellow onion finely. Finely diced onion cooks quickly and incorporates well into the sauce. Mince the garlic cloves finely. Minced garlic releases its flavor readily and infuses the sauce effectively.
Heat olive oil in a large skillet over medium heat. Allow the oil to heat up until it shimmers. Adding fat to the skillet prevents sticking and helps to sauté the onion and garlic properly.
Add the diced onion to the skillet and sauté for about 5-7 minutes, or until softened and translucent. Sautéing onions softens them and brings out their sweetness. Stir occasionally to prevent sticking and ensure even cooking. Add the minced garlic to the skillet and sauté for another 1-2 minutes, or until fragrant. Garlic should be sautéed briefly until fragrant, being careful not to burn it as burnt garlic can be bitter.
Remove the skillet from the heat and set aside. The sautéed onion and garlic base is now ready to be incorporated into the cheese sauce.
Step 3: Make the Cheese Sauce. In a medium saucepan, combine the cream cheese and milk. Using a saucepan with a heavy bottom prevents scorching and ensures even heating for the cheese sauce.
Place the saucepan over low heat. Low heat is important to melt the cream cheese gently without scorching it. Stir constantly with a whisk or spatula until the cream cheese is melted and smooth. Continuous stirring is essential to prevent sticking and ensure a smooth sauce. Once the cream cheese is melted, continue stirring to ensure a homogenous sauce.
Stir in the shredded cheddar cheese and grated Parmesan cheese. Add the cheeses gradually and stir until they are melted and the sauce is creamy and smooth. Incorporate the cheeses fully into the cream sauce, ensuring a smooth and cheesy base. Continue stirring until all cheeses are melted and well combined into the sauce.
Stir in the sautéed onion and garlic mixture into the cheese sauce. Incorporate the sautéed aromatics into the creamy cheese sauce. Add the dried thyme and dried oregano. Season with salt and freshly ground black pepper to taste. Season the sauce generously to enhance the flavors of the cheese, vegetables, and herbs. Taste and adjust seasonings as needed to reach your desired flavor profile. Stir everything together until well combined and heated through. Ensure all ingredients are thoroughly incorporated into the cheese sauce and the sauce is warmed through.
Step 4: Assemble the Casserole. Preheat your oven to 375°F (190°C). Reduce oven temperature slightly from the initial squash roasting temperature for casserole baking.
Lightly grease a 9×13 inch baking dish. Greasing the baking dish prevents the casserole from sticking and makes for easier serving and cleanup. Pour the spaghetti squash strands into the prepared baking dish, spreading them out evenly across the bottom of the dish. Create an even layer of spaghetti squash in the baking dish to ensure even distribution of sauce and cheese.
Pour the cheese sauce evenly over the spaghetti squash in the baking dish. Coat the spaghetti squash strands completely with the creamy cheese sauce. Ensure the sauce is distributed uniformly over the squash for every bite to be cheesy and flavorful.
If desired, sprinkle additional shredded cheddar cheese or Parmesan cheese over the top of the casserole. Adding extra cheese on top creates a golden brown and bubbly cheesy crust during baking. For an optional crispy topping, you can sprinkle breadcrumbs over the cheese. Breadcrumbs add textural contrast and visual appeal to the casserole topping.
Step 5: Bake the Casserole. Bake in the preheated oven for 20-25 minutes, or until the casserole is heated through, bubbly, and the cheese on top is melted and lightly golden brown. Baking time will vary slightly depending on your oven and the depth of the casserole dish. Check for doneness by ensuring the casserole is heated through, bubbly around the edges, and the cheese topping is melted and lightly browned. Monitor the casserole during baking and adjust baking time as needed to achieve desired browning and bubbling.
Step 6: Garnish and Serve. Once the Easy Spaghetti Squash Casserole is baked to golden brown and bubbly perfection, remove the baking dish from the oven. Carefully remove the hot baking dish using oven mitts.
If desired, garnish with fresh chopped parsley. Sprinkle fresh parsley over the hot casserole for a pop of color and fresh flavor. Fresh parsley adds a bright and herbaceous finish.
Let the casserole cool slightly for a few minutes before serving. Allowing the casserole to cool slightly makes it easier to serve and prevents burning your mouth. Serve the Easy Spaghetti Squash Casserole hot and enjoy. Serve it as a main course or a side dish. It’s delicious on its own or alongside a simple salad or roasted vegetables.
USEFUL TIPS:
For a richer flavor, consider using a combination of cheeses in the casserole. In addition to cheddar and Parmesan, you could add Gruyere, Monterey Jack, or a touch of smoked Gouda for complexity. Experimenting with different cheese combinations can elevate the flavor profile and create a more nuanced taste.
To add more vegetables to the casserole, consider incorporating sautéed mushrooms, spinach, bell peppers, or zucchini. Sauté vegetables separately before adding them to the casserole to ensure they are cooked through and not watery. Adding vegetables increases the nutritional value and adds more flavor and texture.
For a protein boost, you can add cooked chicken, turkey, sausage, or chickpeas to the casserole. Cook protein separately before adding it to the casserole. Adding protein makes it a more substantial main course meal. Ensure any protein added is fully cooked before incorporating it into the casserole.
If you want a spicier casserole, add a pinch of red pepper flakes or a dash of hot sauce to the cheese sauce. Red pepper flakes or hot sauce will add a subtle heat that complements the creamy cheese and mild squash. Start with a small amount and adjust to your spice preference.
To prevent the casserole from drying out during baking, make sure the cheese sauce is sufficiently creamy and that the squash strands are not too dry. If the sauce seems too thick, add a splash more milk. Ensure the squash is not over-roasted or microwaved to prevent dryness. A creamy sauce and properly cooked squash will result in a moist and satisfying casserole.
For a crispy topping without breadcrumbs, you can broil the casserole for the last 1-2 minutes of baking. Broiling creates a nicely browned and slightly crispy cheese topping. Watch carefully to prevent burning under the broiler. Broiling provides a quick way to achieve a golden and bubbly top.

NOTES:
One note on spaghetti squash preparation is that roasting it cut-side down helps to steam the squash and keeps it moist. Roasting cut-side down creates a steamy environment within the squash halves as they roast, preventing them from drying out and promoting even cooking. This technique results in tender and easily strandable spaghetti squash.
Another note is to season the cheese sauce generously. Cheese sauces can sometimes be bland if not properly seasoned. Don’t be shy with the salt and pepper, and taste and adjust seasonings throughout the sauce-making process. Proper seasoning is essential for flavorful cheese sauce. Herbs like thyme and oregano also contribute significantly to the flavor depth of the sauce and casserole.
For easier cleanup, consider using disposable aluminum baking pans for casseroles, especially for potlucks or gatherings. Disposable pans eliminate the need for washing casserole dishes and are convenient for transport and serving. Aluminum pans are readily available and practical for casserole baking.
If you want a more golden brown and bubbly topping, you can broil the casserole for the last 1-2 minutes of baking time. Broiling provides intense top-down heat to quickly brown and bubble the cheese topping. Watch carefully under the broiler to prevent burning; broiling can brown food very quickly. Broiling is a quick way to enhance the visual appeal and texture of the casserole topping.
FREQUENTLY ASKED QUESTIONS:
Q: Can I use pre-shredded spaghetti squash to save time?
A: While pre-shredded spaghetti squash is not commonly available in grocery stores, you can sometimes find pre-cut spaghetti squash halves or pieces that are ready for roasting or microwaving. Using pre-cut squash can save some prep time in halving and seeding the squash.

Q: Can I make this casserole vegan or dairy-free?
A: Yes, this Easy Spaghetti Squash Casserole can be adapted to be vegan or dairy-free with some substitutions. To make it vegan and dairy-free, substitute the cream cheese and cheddar cheese with vegan cream cheese and vegan shredded cheddar cheese alternatives.

Vegan Parmesan cheese alternative can also be used or omitted. With these substitutions, you can enjoy a delicious vegan and dairy-free spaghetti squash casserole.
Q: What are good side dishes to serve with spaghetti squash casserole?
A: Easy Spaghetti Squash Casserole is often hearty enough to be a main course itself, but if you are serving it as a side dish or want to round out the meal, consider pairing it with lighter options. A simple green salad with vinaigrette provides a fresh and contrasting element to the richness of the casserole. Roasted vegetables such as broccoli, asparagus, or green beans add extra nutrients and fiber and complement the casserole flavors. Garlic bread or crusty bread can be served on the side for soaking up the cheesy sauce. Choose side dishes that balance the richness of the casserole and offer textural and flavor contrast.
Q: Can I freeze leftover spaghetti squash casserole?
A: Yes, leftover Easy Spaghetti Squash Casserole can be frozen for longer storage. Allow the casserole to cool completely to room temperature first. Cut the casserole into individual serving portions if desired for easier thawing and reheating later.

When ready to serve, thaw the frozen casserole in the refrigerator overnight. Reheat thawed casserole in the oven at 350°F (175°C) until heated through and bubbly.

STORAGE INSTRUCTIONS:
To ensure your Easy Spaghetti Squash Casserole stays fresh and delicious for as long as possible, proper storage is essential. Allow the casserole to cool completely to room temperature before storing. Do not place hot food directly into the refrigerator, as this can create condensation and affect the texture and safety of the leftovers.

Wrap each portion tightly in plastic wrap or aluminum foil. Wrapping each portion individually helps to maintain freshness and prevent freezer burn if freezing.
For refrigerator storage, place the wrapped portions or the whole casserole in an airtight container or cover the baking dish tightly with plastic wrap or aluminum foil. Airtight containers prevent air exposure and help to maintain moisture and flavor during refrigeration.
Store the airtight container of leftover casserole in the refrigerator. Refrigerate leftovers promptly within 2 hours of cooking to ensure food safety. Store in the refrigerator at a temperature of 40°F (4°C) or below. Proper refrigeration is essential for preventing bacterial growth and maintaining food safety.
Consume refrigerated leftovers within 3-4 days for the best quality and food safety. While leftovers may remain safe to eat for longer, the texture and flavor of casseroles can degrade over time. For optimal taste and texture, it is recommended to consume leftovers within this timeframe. Always use your senses – sight, smell, and taste – to assess the quality of leftovers before consuming.
