This Low-Carb Baked Spaghetti Squash is a casserole with tons of flavor thanks to the creamy cheeses, spices and tomatoes. Your family won’t complain about the lack of “real” pasta and they will ask for seconds.
We love using spaghetti squash in dishes where we usually use some kind of pasta. It lightens up the dish a bit and tastes just as good – and often better!
In this Low-Carb Baked Spaghetti, we use ground beef but you definitely could use ground pork, sausage, Italian sausage, ground turkey (basically your ground meat of choice).
We used regular diced tomatoes in our version of this casserole. However, you can find them with the spices already included, like basil, oregano and garlic. You could definitely use a couple of cans of those tomatoes and not add the extra spices.
