Easy Keto Low-Carb Pizza Casserole is a quick healthy recipe perfect for meal prep. This dish is baked with cream cheese, pepperoni, and ground beef, a great crustless pizza substitute.

The idea for this casserole came to me for a few reasons. For starters, I see a lot of people who are following a keto diet, post that they eat the cheese and toppings off their pizza and they toss out the crust.
This is a huge waste of food, this casserole is BETTER and won't waste a bunch of food! I also have a thing for casseroles and I have several popular dishes on the site.
If you are looking for a breadless option with no crust that is made without cauliflower, keep scrolling my friend!

How Long Will it Last in the Fridge
The casserole will last for 3-4 days (covered) in the refrigerator.
Can You Make the Casserole Ahead of Time?
You can make most of the casserole ahead of time. You can cook the ground beef and the cream cheese and marinara.
If you plan to make the dish ahead I do not recommend you add the cream and eggs. Save that, along with the shredded cheese for right before you bake the dish in the oven.
Is it Freezer Friendly?
Cream isn't usually an ingredient you want to freeze. I have frozen this casserole, fully cooked. Upon reheating, it was still good, but it did not taste as good as it would if you eat it within a few days.
Casserole Substitution Tips
You can make changes to this dish and switch it up however you like. If you omit the eggs, your casserole will likely fall apart very easily. You can not taste the eggs in this recipe.
- Ground Turkey
- Bacon
- Chicken
- Green Peppers
- Olives
- Mushrooms

Easy Keto Low-Carb Pizza Casserole
Ingredients
- 1 teaspoon olive oil
- ½ cup chopped onions
- 2 garlic cloves
- 1 pound ground beef
- 1 teaspoon Italian Seasoning
- Salt and pepper to taste
- 1 cup marinara sauce I recommend Raos or you can make homemade marinara using the recipe linked above in the blog post.
- 2 oz cream cheese
- 2 eggs, beaten
- ½ cup heavy cream
- 2 cups mozzarella cheese
- 12 slices pepperoni I used uncured, nitrate-free.
Instructions
- Preheat oven to 350 degrees.
- Drizzle the olive oil in a skillet on medium-high heat. Add the onions. Cook for 2-3 minutes or until fragrant and translucent. Add in the garlic and stir.
- Place the ground beef in the skillet along with Italian seasoning, and salt and pepper to taste. Using a meat chopper, break the ground beef into chunks. If you have excess fat on the beef, drain it from the pan.
- Add the cream cheese and marinara. Cook until the ground beef is no longer pink and the cream cheese has melted.
- Remove the skillet from heat.
- In a medium bowl, combine the eggs, ½ cup shredded mozzarella, and heavy cream.
- Spray a 9x13 pan with cooking oil spray if it isn't a nonstick pan.
- Add the ground beef mixture to the 9x13 casserole dish.
- Drizzle the egg and cream liquid mixture on top.
- Sprinkle the remaining 1 ½ cup shredded mozzarella on top.
- Add the pepperoni.
- Bake for 15-20 minutes or until the cheese begins to bubble. I like for the cheese to brown at the corners of the pan. Mine was ready around 17.
- Cool before serving.

Notes
- If your ground beef has a lot of fat, drain it from the pan before adding the cream cheese and marinara.
- Eggs are used as a binder. The dish does not taste like eggs. If you omit the eggs, the casserole will fall apart.
- If you want the pepperoni visible on top of the casserole, be sure to add the pepperoni after you have added the shredded mozzarella.
- The casserole will last in the fridge for 3-4 days.
- Cream isn't usually an ingredient you want to freeze. I have frozen this casserole, fully cooked. Upon reheating, it was still good, but it did not taste as good as it would if you eat it within a few days.

Veronica Gonzales says
Can we use ground chicken
staysnatched says
If you want. I’ve never tried it.
Ikea says
As always, your recipes never disappoint! And you were right there is no egg taste at all. This is coming from a person who does not like eggs.
staysnatched says
Awesome! I'm so glad you enjoyed the recipe!
Peggy says
This is so good! Made it last week & again tonight! Thank you!!!
staysnatched says
Awesome! So glad you liked it!
Alyssia says
This recipe is AMAZING!!! My boys (picky eaters) love your recipe!!!
staysnatched says
I love when I can satisfy a picky eater!
Trista A. says
This recipe was super easy to whip together after work, and it's ready in no time. It is delicious and I can't wait to try other pizza topping ingredients. I didn't have any onions, so I used onion powder. It worked in a pinch since we're trying to stay out of stores. I will definitely make this one again.
staysnatched says
I love that you were able to improvise!
S says
My first recipe I tried of yours and it is absolutely delicious! Even my mom, who is a super picky eater, enjoyed this and has requested me to make it again soon. I did make it with ground chicken instead o beef though because that’s what I had and it was delicious! Thank you so much for the easy to make, yet such a delicious dish! Saw a lot of your recipes using air fryers and even ended up getting your recommended air fryer because i can tell those recipes are going to be amazing too!
staysnatched says
Congrats on the air fryer! Enjoy it!
Courtney says
I made mine with country sausage instead of ground beef and sprinkled some chopped green olives on top of the sausage mixture and then added the rest and it turned out great. My daughter is 21 months and she couldn’t stop asking for bites!
staysnatched says
I love that!
Stefanie Parker says
Do yourself a favor and make this recipe! It was a great pizza replacement for my keto lifestyle, and super easy to make. I am a picky eater and not the biggest fan of cooking, and even I will be making this regularly now.
staysnatched says
I love when I can please a picky eater!
Reagan says
This was delicious!!! It tasted even better the next day for lunch.
staysnatched says
Just how I like it!
Debbie says
I made this for dinner tonight. I’ve made other low carb pizza casseroles, but this is by far the best. It stayed together, didn’t taste eggy at all and was delicious, plus we have enough left for lunches. Pinning it and putting it on my make again list!
staysnatched says
Yes! So glad you enjoyed it!
Jamie says
This was easy and delicious! I added green peppers, mushrooms, and some crushed red pepper. Thanks!
staysnatched says
Oh I love the sound of that!
Kristen says
This was a crowd pleaser and reminded me of lasagna. I’ve been missing a good lasagna and this hit the spot I didn’t know I was missing. For the kids, we threw som in a tortilla for a healthy version of a “hot pocket”.
staysnatched says
I love that idea!
Nicki says
This was so good!!! I sprinkled some oregano and Parmesan cheese on top and drizzled a little olive oil on the top while it cooked and It was perfect.
staysnatched says
That sounds amazing! I'm glad you enjoyed it.
Erin says
This recipe was delicious, simple, and reminded me of a noodle-free lasagna. It held together nicely and I can’t wait to heat it up for leftovers tomorrow.
staysnatched says
It's so good for leftovers!
Robin says
I made this for dinner last night and it was a huge hit! You can’t taste the egg at all and it was perfect reheated today too. I used ground chicken because I had that on hand. Can’t wait to try more of your recipes!
staysnatched says
You can't taste the egg at all! It's there for structure. Thanks for sharing.
Crystal says
My family loves this recipe! I added some olives and bell peppers do the casserole was more like a supreme pizza. We will be adding this to our dinner rotation.
staysnatched says
A supreme pizza sounds so good!
Jennifer says
This recipe was very easy to make. The filling reminded me of lasagna as I was putting it together. It portioned perfectly into a medium muffin silicone; making 12 mini casseroles. Everyone in my family loved the pizza bites!
staysnatched says
It definitely is like a lasagna!
KD says
I made this for meal prep and it was sooo good! I am not on keto, but I enjoy low carb foods. I made it as above but I added crushed red pepper flake and it gives the ground meat a sausage like taste, and Thinly sliced green peppers and mushrooms to the top. Sooo good and easy!
staysnatched says
That sounds amazing! I love those toppings!
DeAndrea Newton says
Great recipe! Substituted ricotta for the cream cheese because I was out... it still tasted fantastic! The kiddos loved it so that’s a plus!
staysnatched says
That's a great substitution!
Samantha R says
This was so easy to make and so good. I've tried other pizza casseroles and was disappointed in them all. This one is awesome. We added olives and mushrooms and LOTS of pepperoni. This one will definitely be a repeat at our house!
staysnatched says
I'm glad you enjoyed the recipe!
Heather says
Very good! I used turkey Italian sausage and added slices black olives to the meat mixture. Because I used sausage, I skipped the Italian seasoning. The fam loved it and we still have two pieces for lunch tomorrow. Perfect!
staysnatched says
I love your modifications!
Katie Morgan Rupp says
Began making this recipe a while ago and have made it with several different topping options. We are a HUGE pizza family, but sometimes, take out gets old! This recipe is easy and delicious and everyone loves it. Even for those non-keto folks, its still a great, hearty meal and they don't miss the crust! Great Job!
staysnatched says
Yay! I'm so glad you enjoy it!
Kara says

This is so delicious! No egg taste and we didn't miss the 'crust'. I used sausage instead of beef and added green peppers with the onions. It's definitely a keeper.

Julie Guenther says
Thumbs up from my 6 year old grandson! After the first bite or two he said "Wow - Grandma, how did you make this? It is so yummy!"
His mom, dad and sister ate with gusto, as did my hubby. Gobble gobble. Julie
staysnatched says
haha that's funny.
Collier Lewis says
SIMPLY PERFECT! I’m not a big pizza person because of all the bread. This recipe allows me to eat the best part of the pizza… all the toppings! I added mushrooms into my mix and olives on top! So delicious everyone in your home will love it!
staysnatched says
Yum! That sounds delicious!
Allison Keith says
Used ground turkey, it came out very well!
staysnatched says
I'm glad you enjoyed it.
Marlene says
Mine came out runny. I drained my ground beef.
staysnatched says
That’s interesting. Mine doesn’t. Maybe you need to bulk yours up with more ingredients.
Heather says
I have been craving pizza nonstop recently and this recipe is the perfect solution for that when counting calories and trying to eat high protein. Easy to make - love how easy it is to reduce the calories/fat (e.g., if not doing keto) by swapping in lower-fat beef and cream cheese - and delicious! Gotta love being able to quickly satisfy a pizza craving without just ordering pizza (high cost and calorie!).
staysnatched says
So glad to hear!
Deborah says
Winner for us. Made as written. Might mix up toppings next time. Thank you. Will make again for sure.
staysnatched says
So glad to hear it!
Becca says
Does this freeze well?
staysnatched says
It has dairy. Anytime you freeze dairy it separates when you reheat it. It depends on if separation bothers you.
Will says
If you double the recipe will you still double the heavy cream?
staysnatched says
You double all of the ingredients.
Nancy Billeiter says
