Cheesy, gooey, and flavorful, pizza is always on my mind! This Keto Pizza Casserole comes in handy when you have a craving or you’re looking for easy, delicious dinner for the whole family. I like to keep toppings simple with cheese, pepperoni and olives, but feel free to get wild with toppings to satisfy all your cravings!
Your New Favorite Easy Keto Dinner
What’s not to love when you combine hearty Italian sausage, tender cauliflower and top it off with cheese and pepperoni? That was a rhetorical question, of course. The best part about this casserole, as well as most others, is that you can have fun with the toppings! Your kids can join in and dinner can become a family time activity. Matt and I love cooking in the kitchen together as we listen to music and feed little nibbles to Julius (our dog). It enhances the flavors of the food and our relationship!
We Love Casserole Recipes!
Casserole recipes are great for meal prep, easy to assemble and whip up quick on any busy weeknight of the week! You can also clean out your kitchen via casserole, by cooking everything down in a skillet, topping it with cheese and baking it until melty and delicious. Some of our favorite casserole recipes are breakfast style. Eggs are filling, tasty and easy to mix in with whatever fillings you have on hand! If you’re egg lovers like us, give our broccoli, cheese and sausage breakfast casserole or cheesy cauliflower breakfast casserole a try. If you prefer something a bit more complex in flavors give our enchilada casserole a try!
Benefits to Pizza Casserole
You heard right, there are finally benefits to pizza! If I could eat one food for the rest of my life it might just be this low carb pizza casserole. So let’s break down what makes this pizza casserole so good for you:
- Pepperoni- High quality pepperoni like the pork and bacon variety from Applegate farms provide high amounts of protein as well as fat. Protein is muscle sparing as well as being the most efficient macro requiring more energy to burn than carbs and fats (1). This is because protein has a higher thermic and makes digestion more work. Aka more calories burned without even trying!
- Cheese- Parmesan cheese and Mozzarella cheese have a fair amount of sodium which is an important electrolyte for those on keto. Plus cheese is a rich source of calcium which is good for your bones.
- Sausage- In the base of this recipe sausage adds structure as well as fat which is very important on a keto diet. Fat will help to keep you satiated and provide fuel for your day.
- Carbs- This keto/ low carb pizza casserole is only 7 net carbs per serving, aka only 7 net carbs per 1/6
So I guess if steak didn’t exist I would say pizza is the perfect food….. Give this Keto Pizza Casserole a try tonight with your family and let us know what you think!
Is Marinara Sauce Keto?
There is a lot of controversy with whether or not marinara sauce should be consumed on keto. In this keto recipe we only use a 1 cup of marinara sauce between 6 servings. That is about 1.75-2 carbs per serving if you use our favorite sauce Rao’s. This sauce is bursting with bright tomato flavor, garlic, and herbs, perfect for keto recipes.
For an even lower carb and more delicious option, try our homemade keto tomato sauce.
Best Keto Toppings
Don’t worry we’re no “weird-DOUGHS” pizza toppings are a must! Low carb pizza casserole is best served with YOUR favorite toppings. Some of our favorites are:
Meats:
- Pepperonis- A classic, crispy pepperoni atop cheesy goodness!
- Sausage- Maybe your feeling a bit extra Italian. Try chunks of freshly cooked Italian sausage or slices of cooked mild Italian links.
- Prosciutto- For the classier pizza connoisseurs this is the topping for you. Thinly slice prosciutto and place it on top of the pizza. Put it under broil for a minute to slightly crisp and viola!
- Ground Beef- Believe it or no ground beef actually makes a great pizza topping, that is for TACO PIZZA! Layer ground beef, cheese, olives, and tomatoes on top. Once out of the oven hit it with some sour cream and lettuce. Simple ground beef never tasted so good!
Cheeses:
- Shredded Mozzarella- This is another classic ingredient that’s essential for making the perfect low carb pizza casserole
- Mexican 3 cheese blend- Believe it or not this works great on pizza too. That is, if you are making a ground beef style taco pizza!
Finishing Touches:
- Olive Oil- A simple drizzle of high quality oil adds a beautiful mild peppery flavor. Try an extra bit of fresh cracked salt and pepper for added flavor too!
- Vegetables- An easy keto way to get in vegetables is just thinly slicing olives and mushrooms to place on top of the low carb pizza casserole
Making Low Carb Pizza Casserole Fancy
Making keto recipes upscale is not only fun but super tasty too! If you want to try a fancier keto/ low carb pizza with minimal prep time check out these quick recipe adjustments:
- Cheese- Sub standard mozzarella for an aged Manchego or parmesan and mozzarella blend. Aged cheeses have a wonderful Umami flavor unbeatable to regular cheeses. Another option is to make cream cheese pockets. Do this by cubing cream cheese into tiny pieces. Tuck the little cream cheese pieces into the top of your casserole before baking. Once you take it out you’ll have gooey and creamy pockets of goodness.
- Meat- Most meats are keto friendly and I find some of the best fancy meats to be super thinly sliced Capocollo or Prosciutto. They are saltier keto/ low carb meats that crisp up well under the broiler on this pizza casserole recipe.
- Toppings: Try finishing your cooked keto casserole with fresh basil, arugula, feta, or pesto a high fat herb sauce. All of these toppings are gluten free keto ideas so no need to stress about any wheat allergens.

Storing and Freezing Keto Pizza Casserole
The great thing about any casserole whether it be keto/low carb or not is that there’s no denying how well they freeze. I recommend you make a big batch of this pizza casserole recipe and storing it for the whole week. Trust us you’ll want leftovers…
Storing
Steps for storing in the fridge are simple. Begin by removing leftovers from your casserole dish and placing them into an airtight container. Place the container into the fridge and it will last up to a week
Freezing
There’s two ways you can go about freezing this keto pizza casserole recipe.
- Pre-portion servings of this recipe and freeze in individual zip lock bags. Remove from freezer the night before to thaw in the fridge
- Freeze the whole casserole dish! I’ve done this before as an easy keto make ahead dinner. Simply cook the original casserole in a metal tin, or even in a standard casserole dish. Remove from oven and allow to fully cool. Once cooled wrap the metal tin in aluminum a few times and place into the freezer.
Reheating
Reheat whole pizza casserole from frozen by placing into a 350 degree oven for 40-50 minutes. For individual servings reheat on a plate in the microwave in 30 second intervals. Or in the oven at 350 for 20-30 minutes. Your family will love you for this quick and delicious dinner!

Made this tonight – it’s delicious! We used frozen riced cauliflower because, well, because I’m lazy…! Very tasty and filling. Thank you!
Roseanne says
My non-keto family loved this recipe so I am making it again this week.
Rachel says
Nice change up from timely crusts!
Cynthia Meyerhoefer says
I’m obsessed with this recipe and make it every other weekend (how often I ordered pizza. Tonight I tried replacing the ingredients, but keeping the idea. I sauteed some onion and mushrooms in a touch of olive oil, added cauliflower to dry it out. Used Alfredo sauce, added cheese, and cooked it until not thin. When I felt it was cooked enough, I added pesto, the cheese on top, more mushrooms, and some cut up chicken breast I had marinated in balsamic vinegar, olive oil, and Italian spices. Popped it in the oven. It was so good. I also feel better because I don’t like to admit that tomato sets off my acid reflux. I might add some broccoli next time.
Cynthia Meyerhoefer says
I did not make clear that I cut up and sauteed the chicken before putting on the pizza
Roseanne says
I am excited about the idea of the Alfredo Sauce as I personally don’t like tomato sauce. Will try it next time.
Shawna says
Pizza is my weakness. I am wondering if this would work with a couple bags of cauliflower rice to make it even quicker. Plus I dont know if I would.like chunks of cauliflower in my pizza. I guess I’m just wierd.
Miranda (KetoConnect) says
It should work! You’ll just want to make sure to drain excess water.
Donna Schmidt says
I made this tonight and it was wonderful!! Even my husband said that it was good and he hates cauliflower.
Connie says
This was a big hit! My husband loves it
Julie says
Looks Amazing!!!
So…..I don’t on a cast iron pan so, could I cook this in a large frying pan, then transfer it to a casserole dish, top with cheese etc. and put in the oven?
Lauren says
I just made this tonight with chorizo chicken sausage that I picked up at Sprout’s. It is definitely one of the best keto meals I have ever made. I’m sure it would taste fine with any type of sausage but I liked the heat from the chorizo spices. Thanks for the recipe!
Kim says
Made this tonight and it was a big hit with my family. So delicious. Can’t wait to make this again. Next week. Lol
Donita says
My Italian soul was missing the flavor of pizza.
Tried this recipe and it was delicious and very filling. My non keto husband loved it too
Melanie Zimmerman says
This recipe is amazing!! I made it with spicy chorizo and it was just SO good!! Though I have never made a KC recipe that was less than amazing!! Thanks so much 🙂

I’m recent to KETO (3mths) and have as expected become very Vitamin and Mineral conscious
First I know you can offer no medical advice, but you come into my home via Utube weekly or more. You state your opinions and leave it to us to make decisions about the topics you discuss. I get that, and understand, so what I am asking is your opinion on the topics I am discussing.
I have recently found out about CRONOMETER and now track my diet religiously. With Cronometer, I have become more and more aware of my daily nutrition. I know I will need supplements. I have seen through my research that vitamins; water soluble and fat soluble and minerals can stay in your cells for more than a day. (Igor Cummins, when talking about D3, says it has a half life every day). From this I have gleaned and he has said one might supplement large quantities of D3 every couple of days and even every couple of weeks. In my non-gold version of Cronometer I get weekly trends of my nutrition. From this I can see what vitamins and minerals I am lacking each day, and which are in surplus daily and weekly. I have seen that the gold version covers a longer trend option, this I think is indicating what should be supplemented. Applying what IGOR has said about D3 to the other vitamins and minerals can I supplement intermittently to bring them to 100%. (trending)?
OR, can I (by Using Cronometer dailies) supplement each day’s missing nutrients (reaching 100% for that day)? Thus on some days where I get all my nutrition for one vitamin or mineral from eating, I would not supplement that day for that particular vitamin or mineral.
I will take a multivitamin every day even if you think my gleaning is correct, but why have the trend section in Cronmeter if it served no nutritional purpose such as my intermittent supplementation idea?
All this being said I have a second question. What method should I use to judge supplements? I am not asking which brand, but what criteria do I apply to make better if not sound choices? This answer is sorely needed by those of us new to KETO
Thank You
PS. I have lost 38 lbs

I would supplement based on your daily needs and if you don’t get it daily, I would supplement based on your needs over a couple of days. You don’t have to be perfect as our needs really vary person to person (the DRIs are just estimates based on an average from the population). For judging supplements I would just do some research on what ingredients are necessary, the bio availability of different supplements and the ingredients and forms of supplements products contain.
Jenn in GA says
Guys! This is SO good! My keto husband misses pizza, so as soon as I saw this in my inbox, I knew I needed to make it.
I used riced cauliflower instead of a head, and it worked great. It could fool you into thinking you’re eating something akin to lasagna as well with that cheese on top!
Thanks for giving us an alternative to our pizza missing woes.
Mary R says
How much cauliflower rice is used for the the pizza recipe? Thank you
Ann says
Wow! This was fabulous! And loaded with veggies. I did my standard which is half spicy, half mild Italian sausage. Thanks for such a great recipe.
Phil Geissler says
Made this today. Delicious and filling!
Louise Nolan says
Hi Megha
Congrats to you both on the pregnancy! Hope your feeling great. What can I use instead of cheese in the base. I’m dairy intolerant but I’d love to make it.
Olivia Kendrick says
I am not sure if you can really replace the cheese, but you can leave it out if you need to
Marissa says
Vegan cheese! Go Veggie is great.
Kris says
Hi Megha, how do you think this recipe would work if you replaced the cauliflower with broccoli? I love cauliflower but it causes lots of digestive problems.
Olivia Kendrick says
I think it should turn out fine. Obviously the taste will be different but it should work!
Carol says
I made this for dinner tonight. My husband, who does not like cauliflower, loved it! My husband and son can’t do dairy, so I used Trader Joe’s Mozzarella shreds on their half and regular mozzarella for my daughter and me. Thanks for a family friendly dish that we all enjoyed.
beverly a bailey says
What size skillet are you using?
Olivia Kendrick says
I think they are using a pretty big skillet. It shouldn’t matter too much as long as the skillet isn’t tiny.
