Spaghetti Squash:

  • 1 large spaghetti squash cut in half, seeds removed
  • 2 Tbsp. olive oil
  • ½ tsp. salt
  • ¼ tsp. pepper

Lasagna Filling:

  • 2-3 Tbsp. olive oil
  • 2 cloves garlic
  • 1 small sweet onion finely chopped
  • 1 small green bell pepper finely chopped
  • 1 lb. ground turkey 93/7
  • 24 oz. spaghetti sauce
  • 2 tsp. Italian seasoning
  • 1 tsp. salt
  • ¼ tsp. pepper
  • 1 cup ricotta cheese
  • 1 cup mozzarella cheese
  • Parmesan grated, optional
  • Parsley finely chopped, optional


How to Bake Spaghetti Squash:

  1. Preheat oven to 425°F.

  2. Cut one large spaghetti squash in half, lengthwise. Scoop out and discard seeds.

  3. Drizzle 1 tablespoon olive oil in each half of the squash and sprinkle with equal amounts of salt and pepper.

  4. Place halves face-down on a parchment paper or aluminum foil-lined baking sheet.

  5. Roast squash in preheated oven for 45-50 minutes, or until squash is tender and shreds easily with a fork.

Lasagna Filling:

  1. While the squash is baking, combine olive oil, garlic, onions, and bell peppers in a medium-sized skillet over medium heat. Sauté for 3-4 minutes.
  2. Push vegetables to the side of the skillet and add ground turkey. Cook turkey over medium heat for 6-8 minutes, or until turkey is cooked through.
  3. Add spaghetti sauce, Italian seasoning, salt and pepper. Stir until combined.

  4. Reduce heat to low, cover and simmer for 5 minutes.
  5. Once spaghetti squash is completely cooked, shred the inside of each half with a fork to form “noodles.”

  6. Divide the ground turkey sauce evenly between the two halves of the spaghetti squash. Next, add 4 oz. ricotta cheese into each boat. Lastly, top each half with ½ cup mozzarella cheese.

  7. Return spaghetti squash boats to the oven and continue baking for 5-10 minutes, or until cheese melts and begins to brown.

  8. Serve with Parmesan and parsley and enjoy!
