Is there such a thing as Spaghetti Squash Lasagna! I thought for a moment about the title of my recipe.
I’m Italian and it was only after my husband said this was the best spaghetti squash he’s ever had that I realized I could title this as a form of lasagna that is keto friendly and grain free.
It all started with a spaghetti squash that sat on the counter for a few weeks. I had no plan, but I did have a can of Italian tomatoes, some fresh mozzarella cheese, pecorino, ricotta cheese, and a pound of mixed ground beef and ground pork. It can also be made with Italian sausage.
When these ingredients come together in the right balance, it’s very reminiscent of lasagna. It has the creaminess of the cheese, the flavor from the meat, a combination of ground pork and ground beef, pulled together by a fresh quick tomato sauce.
Spaghetti Squash lasagna is very easy to put together with little actual prep time.
The squash is oven roasted like I did in this recipe, which gives it a caramelized depth of flavor.
How to Roast Spaghetti Squash
The hardest part of roasting spaghetti squash is cutting it to roast it. You can microwave it for a few minutes to make it easier and then cut lengthwise. Scrape out the seeds and pulp. Place face down in a baking dish with a few inches of water and bake until tender at 400 degrees F.
While the squash is baking, you can make a quick tomato sauce, and brown the meat. I like meatballs in my lasagna, but to make it easier, I add some spices and pecorino cheese to a mix of ground beef and Italian sausage and browned it. It gives you the taste of the meatballs without the trouble, but using left-over meatballs can be a good idea.
I used a combination of beef and pork, but you can use all beef, ground turkey, or even Italian sausage. I flavored the meat the same way I flavor meatballs, with lots of pecorino and parsley.
This is a great recipe to make when you have left over meatballs, such as these paleo meatballs

Use Three Cheeses for Keto Spaghetti Squash Lasagna
I used three cheeses, pecorino (for the meatballs) and for topping, fresh mozzarella and ricotta. If you don’t have pecorino, use parmesan.
