How to Make Baked Spaghetti Squash with Marinara and Mozzarella
-
Preheat your oven to 400°F. Slice the spaghetti squash in half lengthwise, carefully scooping out the seeds to prepare it for roasting. Drizzle the cut sides with olive oil, season with salt and pepper, and place the halves cut-side down on a parchment-lined baking sheet.
-
Bake for 40–45 minutes. Keep an eye on the squash until the flesh feels tender and easily pierced with a fork. Once done, let it cool slightly before handling.
-
Rake the flesh. Flip the squash halves over and, using a fork, gently rake the flesh to create spaghetti-like strands, keeping them nestled inside the shells. This creates the perfect base for your delicious filling.
-
Mix the marinara sauce. In a bowl, combine 2 cups of marinara sauce with 1 teaspoon of Italian seasoning, 1/2 teaspoon of garlic powder, and 1/4 teaspoon of optional red pepper flakes. Spoon this seasoned sauce evenly into each squash boat, gently stirring it into the strands.
-
Top with cheese. Generously sprinkle each squash half with 1 cup of shredded mozzarella and 1/4 cup of grated Parmesan, enhancing the cheesy goodness.
-
Return to the oven. Place the stuffed squash boats back in the oven and bake for another 10–15 minutes. You want the cheese to melt and become bubbly. For an extra golden top, switch to broil for the last 2–3 minutes.
-
Garnish and serve. Sprinkle your freshly baked delights with a tablespoon of chopped basil or parsley for a lovely finish, and serve straight from the shell for a rustic presentation.
Optional: Add a drizzle of balsamic reduction for added flavor depth!
