Among the key ingredients, the spaghetti squash steals the spotlight, acting as a nutritious alternative to pasta. Spaghetti squash is low in calories yet high in fiber and packed with vitamins A and C, making it an excellent choice for weight loss and gut health. The creamy ricotta cheese adds richness while boosting protein content, ensuring each serving is satisfying and healthy. And let’s not forget about mozzarella and Parmesan, which make every bite cheesy and indulgent. It’s truly a well-rounded dish on all fronts!

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

Making Cheesy Spaghetti Squash Casserole is a straightforward process that combines roasting and mixing.

Step 1

Preheat your oven to 400°F (200°C). Cut the spaghetti squash in half lengthwise and scoop out all the seeds. Place the squash halves cut-side down on a baking sheet. Roast for about 30 minutes until the squash is tender.

Step 2

In a mixing bowl, combine the ricotta cheese, half of the shredded mozzarella, Parmesan cheese, garlic powder, Italian seasoning, salt, and pepper. Mix until you get a smooth consistency.

Step 3

Once the spaghetti squash is roasted, scrape out the strands into a bowl. Mix those strands with the cheese mixture and marinara sauce. Return this delicious filling back to the squash halves and top with the other half of the mozzarella. Bake for another 10 minutes, or until the cheese is melted and bubbling.

This step-by-step process not only guides you through making the casserole, but it ensures you keep the kitchen mess to a minimum. I have found that roasting the spaghetti squash first is crucial, as it creates those perfect spaghetti-like strands that beautifully hold the sauce and cheese. So, don’t skip on roasting, we want to achieve that soft and satisfying texture! Remember to keep an eye on the cheese toward the end; it should turn golden brown but not burnt for that perfect finish.

What Are Some Variations and Serving Suggestions for This Casserole?

Cheesy Spaghetti Squash Casserole is versatile, allowing for numerous variations to suit your tastes.

Diet swap

If you’re aiming for a lower-calorie version, consider substituting full-fat cheese with reduced-fat cheese options. You can also layer in some fresh spinach or kale for added nutrition and a pop of color.

Flavor variation

Want to spice things up? Try adding some cooked ground turkey or shredded chicken for extra protein. If you enjoy a bit of heat, sprinkle in some crushed red pepper flakes or a dash of hot sauce. This meal can easily be customized to suit various flavor profiles. For instance, I love experimenting with different cheese varieties such as feta or goat cheese for tanginess. You can also try adding roasted red bell peppers or mushrooms for an extra umami boost. This sweet potato egg casserole offers a different twist on a veggie-packed casserole to try out!

Serving idea

This casserole is delicious on its own or paired with a refreshing salad. I love serving it with a simple garden salad tossed in a light vinaigrette to balance the cheese’s richness. For a heartier meal, serve it with a side of garlic bread or crusty rolls to mop up the sauce. Don’t forget to top it off with fresh basil for that burst of flavor and visual appeal!
