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.

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.
