  • 1 spaghetti squash
  • 1 lb ground sirloin
  • 1/4 tsp salt
  • 1/4 tsp pepper
  • 1/2 medium yellow onion diced small
  • 1 clove garlic minced
  • 14.5 oz can tomatoes crushed
  • 8 oz can tomato sauce
  • 1 Tbsp parsley chopped
  • 1 tsp dried basil
  • 1 tsp dried oregano
  • 1 1/2 cups ricotta cheese
  • 1 tsp dried basil
  • 1 cup mozzarella cheese shredded
  • 1 Tbsp parsley chopped, fresh or dried


  • Prepare squash according to recipe but do not cut the ends off. Cover the "spaghetti" and set aside. Keep the skins.
  • Set a large skillet over medium-high heat and brown the ground beef with onion, garlic, salt and pepper. When beef is cooked through, drain fat then return to medium-high heat.
  • Stir in the crushed tomatoes, tomato sauce, parsley, 1 tsp dried basil and oregano. Bring mixture to boil then immediately reduce the heat to low and let simmer for 45 minutes or until thickened.
  • Set the oven to broil then move rack to 12" from the top of the oven.
  • Divide ricotta cheese evenly between 2 squash halves then spread into an even layer inside of each. Sprinkle 1 tsp of dried basil on top of the ricotta then spoon half of the sauce mixture into each squash. Top squash lasagna halves with mozzarella cheese then sprinkle with parsley.
  • Place squash in oven until the cheese melts—or a bit longer to brown the cheese!


If you’re short on time, just combine your favorite canned marinara sauce and ground beef and take it from there!
