Ingredients

  • 1 large spaghetti squash
  • 1 batch Keto Italian Meat Sauce
  • 1 ½ cups mozzarella cheese shredded

Instructions

    Cup of Yum
  1. Preheat oven to 400°F.
  2. Prepare to roast your spaghetti squash in the oven for 35 minutes using this method.
  3. Once you add the spaghetti squash in the oven, you can start your sauce.
  4. Prepare a batch of my Keto Italian Meat Sauce, which should be ready around the same time the spaghetti squash comes out of the oven and has cooled enough to handle.
  5. Using a fork, separate the spaghetti like strands and add them to a large mixing bowl.
  6. Pour ⅔ of the Italian meat sauce over the top and mix to combine, making sure the squash is well coated in the sauce.
  7. Pour the mixture into a 9x13 casserole baking dish that’s been sprayed with nonstick spray.
  8. Top with the remaining meat sauce and mozzarella cheese and bake for 15-20 minutes or until the cheese has melted and is slightly golden.

Notes

  • Roasting the spaghetti squash gives it extra flavor, but if you're in a hurry, you can use the "cook in the microwave" method instead.
  • If you don't have time to make your own meat sauce and have a low carb version on hand, I do still recommend adding browned ground beef and Italian sausage to it.
  • This also makes a great "make-ahead" meal, so if you roast the spaghetti squash and make the Italian meat sauce ahead of time, you can assemble and bake when you're ready.
