Ingredients

• 1 clove garlic, minced
• 1 tablespoon olive oil
• salt and ground black pepper to taste
• 1 (28 ounce) jar pasta sauce
• cooking spray
• 1 medium red bell pepper, chopped
• 1 medium spaghetti squash
• 1 medium zucchini, chopped
• 0.5 medium onion, chopped
• 0.5 cup shredded mozzarella cheese
• 0.5 cup shredded Parmesan cheese
• 0.5 pound bulk Italian sausage

Recipe Instructions

Step 1

Pierce squash a few times with a very sharp knife. Place squash in a microwave-safe bowl and microwave on high power until squash is tender and a knife can easily poke through the skin, 10 to 13 minutes. Let squash rest, undisturbed, for 10 minutes.

Step 2

Meanwhile, preheat the oven to 350 degrees F (175 degrees C). Spray an 8-inch casserole dish with cooking spray.

Step 3

Heat oil in a skillet over medium heat; stir in sausage, zucchini, bell pepper, onion, and garlic. Saute, stirring occasionally, until veggies are tender and sausage is crumbly and brown, 5 to 7 minutes.

Step 4

Cut open squash and remove and discard all seeds. Scrape out the flesh with a fork and add to the sausage and veggie mixture. Season with salt and pepper and cook over medium heat for 5 minutes. Stir in pasta sauce and transfer to the prepared casserole dish. Top with shredded Parmesan and mozzarella cheeses.

Step 5

Bake in the preheated oven until heated through and cheeses are melted, about 15 minutes.
