📝Shopping list
To make this easy crockpot recipe you will need these basic ingredients:
- lean ground beef* - cooked
- shredded mozzarella cheese*
- pizza sauce*
- onion - diced
- Italian seasoning
- garlic powder
- your favorite pizza toppings
🔪Instructions
This recipe starts with browned ground beef. I like to bulk-brown lean ground beef in my crock pot. I freeze it in recipe-sized portions so that I always have some on hand for quick dump meals.
Of course, this can also be accomplished in a large skillet stovetop. Or - if your slow cooker happens to have a browning feature, like my new one does, you can do it there.
Spray the inside of your slow cooker with a non-stick cooking spray. Add browned beef and onions into the bottom of your slow cooker. Next, add in pizza sauce and all seasonings and stir to combine.
Top with a thick layer of shredded cheese and your favorite pizza toppings. Cover with lid and cook on low for 3-4 hours. Serve and enjoy!
🍽Serving suggestions
There is no wrong way to serve this easy pizza casserole! It is great over riced or mashed cauliflower. Especially if you try to limit carbs or are on a keto diet. If not, it is also great over rice or mashed potatoes. It is even great stuffed into a jumbo baked potato!
It can be scooped into a roll as a great pizza sandwich. OR- it is awesome served as a huge dip-style meal with crusty bread or crackers. We love pretzel flats with this dish!!
Garlic bread is always a great addition! As is a crisp green salad.
Crustless pizza is delicious served over a bed of pasta. Or just spooned into a big bowl for a crustless pizza bowl meal.
🔁Substitutions
- Not a fan of ground beef? Ground turkey, ground chicken and sausage all work perfectly with this crustless pizza recipe! Or try pizza chicken!
- Shredded mozzarella is great for a traditional flare. If you want to zhuzh it up a bit, try mixing your shredded cheese. Shredded sharp cheddar cheese is super yummy mixed with mozzarella. So is pepper jack cheese if want to add a kick. The options for this low-carb pizza casserole are endless.
- Marinara sauce, tomato sauce, or spaghetti sauce can be used in place of pizza sauce if you prefer. To keep this meal as low-carb as possible, use a sugar-free pizza sauce.
