Ingredients
- 1 medium spaghetti squash (about 3 pounds), halved and seeds removed
- 1 tablespoon olive oil, plus extra for drizzling
- 1 small yellow onion, finely diced
- 3 cloves garlic, minced
- 1 cup mushrooms, sliced (cremini or white button preferred)
- 1 cup fresh spinach, roughly chopped
- 1 cup ricotta cheese
- 1 cup shredded mozzarella cheese
- ½ cup grated Parmesan cheese
- 1 teaspoon dried Italian seasoning
- ¼ teaspoon red pepper flakes (optional, for a subtle kick)
- Salt and freshly ground black pepper, to taste
- 2 large eggs, lightly beaten
- Fresh basil leaves for garnish
Instructions
- Roast the spaghetti squash: Preheat your oven to 400°F (200°C). Drizzle the cut sides of the squash with olive oil and season lightly with salt and pepper. Place cut-side down on a parchment-lined baking sheet. Roast for 35-40 minutes or until tender and easily shredable with a fork.
- sauté the vegetables: While the squash is roasting, heat 1 tablespoon olive oil in a skillet over medium heat. Add the diced onion and sauté until translucent, about 4 minutes. Stir in garlic and mushrooms, cooking until mushrooms release their moisture and begin to brown, another 5 minutes. Toss in the spinach and cook until just wilted.Remove from heat and set aside.
- Prepare the squash strands: When the spaghetti squash is cool enough to handle, use a fork to scrape out the strands into a large mixing bowl. Discard the skin.
- Combine the filling: In the bowl with squash, add the sautéed vegetables, ricotta, half the mozzarella, parmesan, Italian seasoning, red pepper flakes, eggs, and a good pinch of salt and pepper.Gently fold to combine,being careful not to mash the strands.
- Assemble the casserole: Transfer the mixture to a greased 9×13-inch baking dish, spreading it evenly. Sprinkle the remaining mozzarella evenly over the top for a golden, bubbly crust.
- Bake: Place the casserole in the oven and bake at 375°F (190°C) for 20-25 minutes, until the top is golden and the filling is set.
- Cool and garnish: Let the casserole rest for 5 minutes post-baking. Garnish with freshly torn basil leaves before serving for a shining, herbaceous finish.
Tips for Success
- Choosing your squash: Select a smooth, firm spaghetti squash free from soft spots or blemishes. medium-sized ones usually offer the best ring-to-flesh ratio.
- Texture balance: Avoid over-mixing the squash to maintain the signature stringy texture reminiscent of pasta strands.
- Make it meaty: For a heartier bake,sauté 1 cup of cooked ground turkey or Italian sausage with the vegetables before mixing.
- Make-ahead friendly: Prepare the squash and vegetable mixture up to 24 hours in advance. Store covered in the fridge and bake fresh before serving.
- Dairy-free option: Replace ricotta and cheeses with a vegan cheese blend or a cashew cream sauce for creaminess without dairy.
Serving Suggestions
This casserole shines as a main course paired with a crisp green salad dressed in lemon vinaigrette or roasted seasonal vegetables.
