How Do You Make Cheesy Spaghetti Squash Casserole Step-By-Step?

This recipe is straightforward and ideal for all cooking levels.

Step 1: Prep and Roast the Squash

Preheat your oven to 400°F (200°C). Take the spaghetti squash and cut it in half lengthwise. Carefully scoop out the seeds with a spoon. Then, place the squash halves cut-side down on a baking sheet. Roast for 30 minutes or until the squash is tender when pierced with a fork.

Step 2: Mix the Filling

While the squash is roasting, mix the ricotta cheese, half of the shredded mozzarella, Parmesan cheese, garlic powder, Italian seasoning, salt, and pepper in a bowl. Combining these ingredients until they form a smooth, cohesive mixture will enhance the overall flavor upon baking.

Step 3: Assemble and Bake

Once the squash is sufficiently roasted, remove it from the oven and use a fork to scrape out the strands into a bowl. Combine these strands with the cheese mixture and marinara sauce until fully blended. Transfer the filling back into the squash halves and top with the remaining mozzarella cheese. Bake the fully assembled casserole in the oven for an additional 10 minutes until the cheese is bubbly and golden.

Lastly, if you’re feeling decorative, garnish the dish with fresh basil to infuse a pop of color and freshness just before serving. This final touch adds a delicate aroma that enhances presentation and taste.

What Are Some Delicious Variations and Serving Suggestions?

Diet Swap

If you’re looking for a dairy-free option, consider replacing traditional cheeses with plant-based alternatives. Vegan ricotta and mozzarella can provide a similar texture and flavor without the dairy. This way, you can enjoy a delicious casserole that fits a vegan or gluten-free diet.

Flavor Variation

For extra depth and flavor, why not add sautéed vegetables such as mushrooms, spinach, or bell peppers to the cheese mixture? This not only boosts the nutritional value but also brightens the overall dish. Spice lovers might even add crushed red pepper flakes for an extra kick! Another delightful option is to swap out the marinara sauce with pesto for an herby infusion that surprises the palate. You can find delicious varieties in this creamy lasagna.

Serving Idea

This Cheesy Spaghetti Squash Casserole pairs beautifully with a light side salad dressed with vinaigrette. Complement it with garlic bread for a carb-inclusive treat that rounds out your meal. It’s a versatile main dish suitable for both casual weeknight dinners and festive occasions.

Suggested Pairings	Tips
