How to Make Spaghetti Squash Lasagna
-
Preheat your oven to 400°F. This ensures your spaghetti squash roasts perfectly, becoming sweet and tender, ready to embrace the delicious filling that’s coming its way.
-
Roast the spaghetti squash. Cut them in half lengthwise, scoop out the seeds, and drizzle with olive oil, salt, and pepper. Place cut-side down on a baking sheet and roast for 30-40 minutes until tender.
-
Sauté ground turkey in a large skillet. Heat 1 tablespoon of olive oil over medium-high heat. Add turkey, 1 teaspoon salt, ½ teaspoon pepper, Italian seasoning, and red pepper flakes. Cook until browned, about 4 minutes. Stir in the minced garlic, cooking until fragrant, around 1 minute.
-
Simmer the sauce. Reduce heat to low and stir in the tomato pasta sauce and red wine vinegar. Allow the mixture to simmer for about 1 minute, adjusting seasoning as desired for perfect flavor.
-
Combine spinach and cheese in a mixing bowl. Separate clumps of the thawed spinach, then mix in ricotta, ½ cup fontina, and the remaining ½ teaspoon salt using a fork to create a creamy filling.
-
Fluff the squash. Once cool, use a fork to fluff the insides of the spaghetti squash, turning it into delightful strands. Add them to your mixing bowl with the spinach mixture and stir to combine.
-
Fill the squash halves. Spoon the ricotta and spaghetti mixture back into the squash halves. Pour your savory tomato sauce over the top, and finish with the remaining fontina and Parmesan cheese.
-
Bake until melty. Place the stuffed squash back in the oven and bake until heated through and the cheese is beautifully melty, about 10 to 15 minutes.
-
Broil for a golden finish (optional). If you like a bubbly, golden top, turn the oven to broil and watch closely as it broils for about 2 minutes. Remove once it’s bubbly and golden, then sprinkle with fresh parsley before serving.
Optional: Add a sprinkle of crushed red pepper flakes for an extra kick!
