Homemade Spaghetti Squash Pizza Casserole

Ingredients You’ll Need

For the Spaghetti Squash:

  • 1 medium spaghetti squash
  • Olive oil, for drizzling
  • Salt and pepper, to taste

For the Toppings:

  • 1 cup marinara sauce (store-bought or homemade)
  • 1 ½ cups shredded mozzarella cheese
  • ½ cup sliced pepperoni (or your favorite toppings)
  • ½ cup chopped bell peppers
  • ½ cup sliced mushrooms
  • 1 teaspoon Italian seasoning

For Garnish:

  • Fresh basil leaves, for serving
  • Grated Parmesan cheese, optional

Tip: When selecting spaghetti squash, look for a firm and heavy one with a smooth skin. If you prefer, you can substitute the cheese with a dairy-free option or omit toppings for a vegetarian version.

How to Make Homemade Spaghetti Squash Pizza Casserole

  1. Preheat the Oven: Start by preheating your oven to 400°F (200°C).
  2. Prepare the Squash: Cut the spaghetti squash in half lengthwise and scoop out the seeds. Drizzle the inside with olive oil and season with salt and pepper.
  3. Roast the Squash: Place the squash halves cut-side down on a baking sheet. Bake for 30-40 minutes, or until the flesh is tender and can be easily scraped with a fork.
  4. Shred the Squash: Once roasted, take the squash out of the oven and let it cool slightly. Using a fork, gently scrape the flesh to create spaghetti-like strands.
  5. Combine Ingredients: In a large mixing bowl, combine the shredded squash with marinara sauce, Italian seasoning, and half of the mozzarella cheese. If desired, add in any vegetables or toppings at this stage.
  6. Layer the Casserole: Transfer the mixture into a greased 9×13-inch baking dish. Spread the remaining mozzarella cheese on top and arrange the pepperoni slices evenly.
  7. Bake the Casserole: Return the dish to the oven and bake for another 20-25 minutes or until the cheese is bubbly and golden brown.
  8. Serve: Once out of the oven, let it cool for a few minutes. Top with fresh basil leaves and grated Parmesan, if using. Enjoy!

Expert Tips & Ideas

  • Freezing: This casserole freezes well! Just make sure to allow it to cool completely before transferring to airtight containers. It keeps well for up to three months.
  • Vegetarian Option: Skip the pepperoni and load up with more veggies like spinach, zucchini, or olives for a delicious vegetarian version.
