I think this Spaghetti Squash Casserole is my new favorite recipe on the blog. You see, I am not ashamed to admit that I ate the whole casserole. It was my lunch for over a week and I think I could eat it everyday if I had to!
I have really grown fond of spaghetti squash, especially after I learned the best way to roast it for ultimate flavor! I featured that in my recipe for spaghetti squash soup.
I made this the ultimate spaghetti squash casserole by loading it with my favorite pizza flavor...meat lovers! This casserole is full of ground beef, sausage, pepperoni, and mozzarella cheese. So delicious!
HOW TO MAKE SPAGHETTI SQUASH CASSEROLE
To get started, cook your spaghetti squash and remove the flesh. I give you instructions for my favorite in the recipe card.
While the spaghetti squash is cooking, you can go ahead and get the ground meats cooked. Cook them in the same skillet to save some time.
Now we just assemble everything right in the baking dish and mix it all up!
That would be the spaghetti squash, marinara, ground beef and sausage, and cheese.
I use jarred marinara but you can also use my recipe for keto marinara sauce.
Mix it up really well, flatten it out a little, top with with more cheese, the pepperoni, then bake it in the oven!
It is a bubbling beauty when you pull it out of the oven. I'm obsessed.
