Ingredients

3 cups uncooked spiral pasta

1 medium yellow summer squash

1 small zucchini

1 medium sweet red pepper

1 medium green pepper

1 tablespoon olive oil

1 small red onion, halved and sliced

1 cup sliced fresh mushrooms

1/2 teaspoon salt

1/4 teaspoon pepper

1/4 teaspoon crushed red pepper flakes

1 jar (24 ounces) spicy marinara sauce

8 ounces fresh mozzarella cheese pearls

Optional: Grated Parmesan cheese and julienned fresh basil

Instructions

  1. Preheat oven to 375°F (190°C).
  2. Cook pasta according to package instructions until al dente. Drain and set aside.
  3. Chop squash, zucchini, and peppers. In a large skillet, heat olive oil over medium heat. Add onions, mushrooms, and chopped vegetables. Season with salt, pepper, and crushed red pepper flakes. Sauté 5–7 minutes until slightly softened.

  5. Transfer mixture to a greased 9×13-inch baking dish. Sprinkle mozzarella cheese evenly on top.
  6. Bake uncovered for 20–25 minutes until cheese is melted and bubbly.
  7. Optionally sprinkle with grated Parmesan and fresh basil before serving.

Notes

Add other vegetables such as broccoli, eggplant, or spinach.

Use vegan cheese for a dairy-free version.

Swap spicy marinara for mild marinara if desired.

Mix in cooked Italian sausage or chicken for a non-vegetarian option.
