Low Carb Pizza Casserole

When you’re low carbing and all you can think about is pizza, you don’t have to miss out. This low carb pizza casserole is crustless but still packs a lot of flavor because it’s filled with your favorite toppings (and lots of cheese). You won’t even miss the pizza crust… Promise!

I’ve hesitated sharing this post. Not because I don’t want you to have it… That’s not it. But it’s not the healthiest recipe on the block in terms of fat and calories. Now, on our low carb diet, we’re not too concerned with the fat content. But I get that some of you low carbers are, so if you’re one of them, try ground turkey and lower fat cheeses in your pizza casserole. You may even want to skip the pepperoni or try turkey pepperoni. It’ll be delicious any way you slice it.


Low Carb Pizza Casserole in the Crock Pot


You don’t have to make this in the crock pot. If you prefer the oven, do that. Or if you just want to add everything to a big skillet, you can do that, too. We just prefer the crock pot because I can toss the ingredients in mid-afternoon, and it’ll be hot and ready by dinner time.

And yes, the 2-hours on low is correct. I cook the ground beef and veggies before I put them in the crock pot. If you don’t (which I don’t recommend because it would be totally greasy), you’ll need to adjust your cooking time accordingly.

Servings 6 servings


  • pepperoni slices
  • 1 lb. ground beef
  • 1 14-oz jar pizza sauce
  • 1 large green pepper
  • 1 medium onion
  • 1 8-oz package baby bella mushrooms
  • 2 cups shredded mozzarella cheese


  • Dice green pepper, onion and mushrooms.
  • Add veggies and ground beef to pan. Cook until ground beef is browned and veggies are tender. Drain.
  • In crock pot, layer ground beef and veggie mixture, sauce, cheese and pepperoni. Repeat layers.
  • Cook on low in crock pot for 2 hours, until cheese is melted and and casserole is heated through.

And there you have it! Now, if the casserole is still really hot when you try to serve it, it’s going to fall apart into a cheesy, tasty mess. To slice it like you see in the pictures, you need to allow it to cool. But it’s just as tasty when it’s messy, so I wouldn’t worry about that.

    • I typically use my 6-quart crock pot, but I’ve used smaller ones, too (like my 3 qt.). If you want to fill the crock pot (6 qt.) you’ll need to double or triple this.

    • Everything is already technically “done” by the time it goes in the oven, so just long enough to heat all the cheeses and get it bubbly. About 20 minutes in my oven at 350, but yours may take a bit longer. You may want to cover it with foil until the last 5 minutes or so to make sure the cheese on top doesn’t scorch. Hope that helps!

  2. Made this tonight and LOVED it!!! DId ground turkey, turkey pepperoni and it was still amazing! Did not double the recipe and it did 2 layers in my large crock pot. Thanks for the recipe!!

  3. Love this recipe. I’ve made it in the oven and in the crock pot, fills a 9 in square pan. I’ve even taken it to a pot luck and was lucky to get any, everyone wanted my recipe. Thank you for such a delicious and easy to throw together meal.

  4. Made this tonight in my cast iron skillet! No mushrooms…but it was SO good! Used turkey Italian sausage. Hubby loved it! Thanks so much!
