Ingredients

  • 1 spaghetti squash, halved and seeded

  • 1 pound lean ground beef

  • ½ cup finely chopped onion

  • ½ cup minced bell pepper

  • 1 clove garlic, minced

  • 1 teaspoon dried basil

  • 1 teaspoon dried oregano

  • ½ teaspoon salt

  • ¼ teaspoon ground black pepper

  • 1 (14.5 ounce) can diced tomatoes, drained

  • ⅓ cup shredded Cheddar cheese

Directions

  1. Preheat the oven to 375 degrees F (190 degrees C). Place squash, flesh-side down, in baking pan; pour in enough boiling water to come 1/2-inch up the sides of dish.

  2. Bake in the preheated oven until squash is tender, 40 to 45 minutes. Remove from oven; cool until easily handled, 7 to 10 minutes.

  3. Reduce oven to 350 degrees F (175 degrees C). Scoop out squash; separate strands with a fork. Reserve shells.

  4. Cook beef, onion, and bell pepper in a skillet over medium heat until the meat is no longer pink, about 5 minutes; drain. Stir in garlic, basil, oregano, salt, and pepper; cook and stir until fragrant, about 2 minutes. Add tomatoes and cook until warmed through, about 2 minutes. Stir in squash; cook until liquid has evaporated, about 10 minutes.

  5. Fill squash shells with squash mixture using a slotted spoon; place in a shallow baking pan.

  6. Bake in the preheated oven until flavors combine, about 15 minutes. Sprinkle with Cheddar cheese; bake until cheese is melted, about 5 minutes.

Cook’s Note

You can use any ground meat instead of ground beef. Mozzarella cheese works well if you prefer it to Cheddar.
