    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 way in the recipe card and I also use this method for my Italian Stuffed Spaghetti Squash Boats.

    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.

    Nutrition per serving (8 servings total):395 calories / 30g fat / 12g sat fat / 9g carbs / 2g fiber / 23g protein
     
    My favorite way to cook spaghetti squash:
    Pre-heat the oven to 460F. Using a fork or sharp knife, poke holes in the spaghetti squash and microwave for 5 minutes. Let cool enough to handle. Cut the squash in half lengthwise, remove the seeds, and brush each side 1 tablespoon of avocado oil and season with ¼ teaspoon of salt. Place face down on a baking sheet and roast for 20-25 minutes until tender.  Remove from the oven, let cool to handle, and scrape out the flesh with a fork.
    Servings: 8

      This recipe was a huge hit with my family! Though I am the only one who pays any attention to carbs, the family went back for seconds and thirds. I'm making it again tonight as we all loved it so much.

      I found your site over on instagram and so glad I did. This looks amazing and my family will love this. I plan on making it this weekend for them. My kids are not full on low carb, so when I can serve them something like this that doesn't sacrifice any of the taste of pizza than I'm all for it. Than ks
