Ingredients

  • 1 lb ground beef
  • 1/2 jar low carb spaghetti sauce (see low carb sauce suggestions in post)
  • 1 whole spaghetti squash
  • 6 oz Ricotta Cheese
  • 1/2 cup Parmesan cheese
  • 1 1/2 cup Mozzarella Cheese
  • 1 medium egg
  • 1/2 teaspoon Italian Seasoning
  • 4 cloves garlic minced

Instructions

  • Brown ground beef and minced garlic, then drain if desired.
  • Add low carb spaghetti sauce to the meat mixture and simmer with a lid on the pot for about 10 minutes.
  • Pierce spaghetti squash with knife and cook for 5 min in microwave.
  • Cut in half and dig out seeds then brush the insides with a light coat of olive oil and salt/pepper. Place facing down on a baking sheet and bake approx 25-35 min in a 375- degree oven until tender. Cooking times will vary depending on the size of the spaghetti squash. You'll want it to be a bit al dente since you will bake it again once the lasagna boats are assembled.
  • Remove from the oven when done and allow to cool for 5 min.
  • With a fork, scrape out the inside of the spaghetti squash, leaving the spaghetti squash inside the shell to make a "boat."
  • Combine 6oz of Ricotta cheese, 1/4 cup Parmesan cheese, egg, and Italian seasoning.

To assemble Spaghetti Squash boats:

  • Spoon the ricotta cheese mixture on top of the loosened spaghetti squash.
  • Add spaghetti sauce
  • Top with mozzarella cheese and remaining Parmesan cheese, then sprinkle a little Italian seasoning on top.
  • Bake in a 400-degree oven for 25 minutes.
