I love a recipe that makes my family ask “I thought you weren’t eating carbs?” because they could never guess that what they are eating is actually low carb. This Upside Down Pizza Casserole does just that!
It has all the flavors that you crave in a good pizza with a fraction of the carbs. It comes together easily and can even be made ahead of time for a quick weeknight supper! Add in your favorite pizza toppings to customize it to your taste for the PERFECT low carb craving killer!

In my family, we take our pizza seriously. I am well known among my kids’ friends, for my AMAZING homemade pizza and breadsticks. I make everything from scratch, and it’s delicious if I do say so myself! Unfortunately, it is FAR from low carb, so it’s now something I only make on special occasions.
When transitioning to keto, and especially when trying to get your family on board, I think it’s much easier to stick to foods that your family is familiar with. And since everyone is familiar with pizza, this recipe will do just that!
Ingredient substitutions:
- Ground Beef – Ground turkey or Italian sausage would work great in place of the ground beef.
- Low Carb Marinara – Really any marinara sauce will work, but if you are counting carbs I recommend my recipe for easy low carb marinara or Rao’s Marinara sauce.
- Pizza Toppings – For this recipe, I just went with the classic pepperoni, but the sky is the limit here! If you like it on your pizza feel free to use it in this casserole!
- Almond Flour – I always get asked about substitutions for the almond flour. The crust recipe is essentially a fathead dough with some extra baking powder mixed in. You can substitute the crust recipe with any fathead dough that you like (including coconut versions).

Want to make it in advance?
This recipe makes a great freezer meal! To do this, simply prepare it up until the foil is removed at the end of baking.
Instead, you will remove it from the oven after the 30 minutes of baking, allow to cool and them tightly wrap with foil and/or plastic wrap and transfer to the fridge or freezer.
Ideally, you would want to thaw it at least halfway before baking it from this point. But if you don’t have time just reduce the baking temp a bit and cook covered with foil for 45-60 minutes or until it is heated through.

Upside Down Pizza Casserole | Keto, Gluten Free
Ingredients
Filling:
- 1 lb 80/20 ground beef
- 1 1/4 Cup Low Carb Marinara Sauce
- 1 Cup mozzarella cheese shredded
- pizza toppings of your choice
Crust:
- 1 3/4 cup mozzarella cheese shredded
- 1 oz cream cheese
- 1 1/4 cups Almond Flour
- 2 tsp Baking Powder
- 1 tsp garlic powder
- 1 egg
Topping:
- 1 tbsp butter melted
- 1/2 tsp garlic powder
- 1/2 tsp Onion Powder
- 1 tsp dried parsley
Instructions
- Preheat your oven to 375 degrees F.
- Cook the ground beef and drain the excess grease. Combine the cooked beef with the marinara sauce and spread into the bottom of a greased 7×11 casserole dish.
- Top the meat with about 1 cup of shredded mozzarella cheese, and your favorite pizza toppings.
- For the top “crust” layer, combine the mozzarella cheese with the cream cheese in a medium microwave safe bowl. Heat in the microwave on 30 second intervals until the 2 cheeses are melted and combine easily. Then, add in the almond meal, baking powder, garlic powder and egg.
- Spread this mixture on top of the cheese and toppings in your dish. I find it easiest to place the dough in even clumps on the top of the dish and them smoosh them together using my hands until the entire casserole is covered.
- Cover the pan with foil and bake for about 30 minutes. Remove the foil and bake and additional 10 minutes, or until the top is browned.
- For the butter topping: Combine the melted butter with the garlic powder, onion powder and parsley and brush on top of the “crust.”

Hi just curious would coconut flour work in this vs almond flour? I have a child allergic to almonds. Thank you
You can, but the ratios would be a little different since coconut flour is much more absorbent then almond flour. To ensure a good result, I would check out the coconut flour bagel recipe on lowcarbyum.com, and simply sub the crust in this recipe with that bagel recipe – the result should be pretty similar 🙂
DELICIOUS! I’ve lost 25 lbs. on keto. You never feel deprived eating Upside Down Pizza Casserole. A winner!
Rebecca
Thank you so much, I am so glad that you enjoyed it!! You are totally right, there is a keto friendly substitute for just about anything that you could want. Congrats on your weight loss!!! 25 pounds is AMAZING!!
I have lost 25 lbs. on Keto! Upside-Down pizza casserole is a delicious addition to my recipes!!!
Delicious!! I don’t tolerate almond flour so I subbed it out for a couple tbsp of coconut flour, added and extra egg and total of 2 oz of cream cheese plus increased the mozz to 2 cups. I used hamburger, mini pepperoni, bacon, and Canadian bacon. I would have added more veggies if it wasn’t for my picky teen. Picky teen approved!! Thanks it’s a keeper!!
I’m so glad you all liked it 🙂 and what is it with teenagers? Mine is super picky too all of a sudden, drives me crazy!
I don’t have a 7 x 11 casserole dish. I’ve only got a 9 x 13 or am 8 x 8. Which do you think would be better to use?
Either one should work fine. With an 8×8 you will might need to cook it a tad longer since the dough will be slightly thicker.
Any tips for removing the egg? How about non nut based flours? This looks amazing but our food allergies are lengthy
This is a tough one. I *think* that most flours would work in place of the nut flours, but you would have to play around with the proportions a little. The egg gives the dough a little rise, bust mostly acts as a binder so you could probably just add a little extra cheese in it’s place. Good luck!!
Can you freeze this recipe and bake later?
Yep! I usually bake it just until the top dough layer begins to brown before freezing, otherwise the texture changes a little.
To cook, I thaw it in the fridge and bake until it’s heated through and the top is fully browned.
Made this tonight and it was amazing. Thank you for a good Keto recipe.
So glad that you enjoyed it!
This recipe is absolutely incredible. Everyone in my household gave it a “10.” I have been searching for YEARS for a family friendly alternative to pizza. This casserole is perfec in every way!! A million thanks for developing this “keeper” recipe. It’s phenomenal!
This comment just made my day! Thank you so much! I am so happy that you and your family enjoyed it 🙂
This was delicious! I made it exactly as the recipe states and it turned out great. I used pepperoni and bacon crumbles for the pizza “topping”. Thank you for a yummy recipe!
I am definitely going to toss in bacon pieces the next time I make it! Thanks for the review!
Fabulous Keto recipe! Outstanding hit in this house!!
Could you roll the crust between parchment then lay it on top or is the dough too sticky?
I think you could do that! maybe spray the parchment with nonstick spray just in case. Let me know how it goes!
I made this for dinner, it was excellent. I used a 9×13 pan and it was the same amount of time. I also put the crust in between two sheets of wax paper and pressed it out. Worked great. Thank you for the delicious recipe. I will be making this again soon.
Could you please confirm that the amount of marinara sauce is 1and 1/4 cup. Also the amount of almond flour is 1 and 1/4 cup. Want to make this tomorrow.
Yep – the amounts on the recipe card are correct. Hope you like it!
I made this on Tuesday, I used 1 lb of bulk Italian sausage instead of ground beef. This is the best recipe for pizza for keto people! My husband liked it too. Glad to have been surfing and found this. I will definitely make this again. Oh ,I forgot to mention, I let it set up in the fridge and we had it the next day for dinner.
Thanks so much for the kind review! So glad that you guys enjoyed it!
I can not wait to make this for my family!!! I’m eating low carb so regular pizza just doesn’t cut it these days. This will be the perfect substitute!
Yum!! I have been missing pizza a lot lately. This even made my two teens happy! They said “ it”’s too bad you can’t eat this mom.” When I told them I could they were stunned! It tastes like calzone
Holy Yum! I started keto three days ago, and was thrilled to find this recipe but also skeptical because pizza is my favorite food! I made it tonight for dinner for my family, and my husband (who is not on keto) went back for seconds! My college-age girls loved it as well. I could eat this every day and would make it even if I wasn’t on keto. THANK YOU, THANK YOU!!!
You’re welcome Cheri! Glad you all enjoyed it and welcome to keto! xo
I made this and it’s delish!
Hello Sabra, I made this for supper tonight and both myself and my husband loved it. The only problem I had was smooshing the crust over top with my hands, it kept sticking. Now I’m wondering if the problem was that I used almond flour (as listed in the recipe ingredients), not the almond meal stated in the directions. I think the almond meal would make the crust a little more crispier than mine turned out, although we did enjoy it. Next time I will try the almond meal. Thanks for this recipe, I’ve been craving pizza for weeks now and this one fit the bill.
Glad that you all liked it! Although almond meal or flour should work just fine, that is a typo in the recipe. Other reviewers have suggested rolling out the top layer between 2 sheets of greased parchment, then laying it on top, so if you are having trouble, this sounds like the best solution to me.
Thanks for the review! xo
The recipe states to put one cup of mozzarella cheese on top and then Marinera and beef. Then it states to add mozzarella to cream cheese, would that be the 3/4cup that is left over? Or is it still another 1 3/4 cup ?
On top of the marinara and beef is what that should have said.
Love it! Love it! Love it! I ‘m not a great cook and had my doubts but all turned out perfectM no problem with the crust, just flatten it into two pieces and used my lifter to slide it onto pizza. Topping was mushroom and green pepper.
PS Is there a way I can follow you for recipes?

Do you taste the almond in the dough?
Hi Judy, I have never noticed the dough tasting like almond at all. Hope that helps!
This. Was. Amazing. I, too, added bacon and it was fantastic! Definitely going in my playbook! Thank you!
Trying this tonight as after a month on Keto, my husband would practically kill somebody for a piece of pizza. He really wouldn’t, but it has been his biggest crazing. Fingers-crossed!
I think I did something wrong, the almond flour didn’t really incorporate into the cheese mixture. Suggestions? Still delicious though. I actually made with meatballs.
Make sure that your cheese is REALLY melted before you add in the almond flour and that should help!
Thanks. Perhaps it was just barely melted. I will remember that for next time.
This was great. My husband commented that he would like to see it in the rotation. (He rarely says that, lol!) I am planning to make this for my gluten free daughter and family very soon. I expect it will be a hit!
I am also thinking that it would be great with an Alfredo and chicken sauce instead of the marinara, for a change. Great idea. Thanks for the great recipe!
That’s so great to hear! I definitely think you are on to something with that Alfredo idea 🤔
How does this reheat? Thinking of making it for my lunches next week….
Hi Sarah! We have been on vacation for the past few days and I am slowly making my way through comments, so I hope I am not answering this too late! This casserole reheats really well! The texture of the bread layer does tend to get a little dry when reheating, so I like to add a tad more marinara, or just pour some extra on it before heating it up. Hope that helps!
Looks Amazing will be trying with ground turkey instead of hamburger…should be lil lower on carbs n fat maybe?
Hope you enjoy it! Ground turkey will reduce the calories and fat, if you select a lean ground turkey but the carbs will be the same 🙂
Made last night and the fiancé said it was the best keto recipe we’ve tried so far.
Excellent recipe! Take out pizza was the most difficult thing for me to give up– recipes like this help me to stay on track. Thank you!
I do not need a gluten free recipe. Can I use regular flour instead of the almond flour?
I’m not sure that regular flour would work. You could just substitute a traditional pizza crust recipe for the topping in this though! Hope that helps if you try it let me know how it turns out!
Can this be made without the egg
You can leave the egg out, although the texture will not be quite as bread like.
Hi Sabra, I Did read the comments about a typo. Which would be better the almond flour or Meal? Thank you
Almond flour would be best. If you only have meal, you can pulse it in a blender for a few minutes to make it a bit finer. Hope that helps!
Wonderfull recipe that feels like I’m cheating but NOT!! Even my teenagers love it. It took me three tries before I really mastered the crust but It was well worth it, I love the recipe!!!
It has been hard satisfying my family of 4 while doimg low carb, until I found this recipe. I don’t even feel like I’m on a diet with this recipe. My pizza loving toddler loves it. So easy to throw together. I made this recipe in advance and stored in the fridge for a few days before putting it in the oven and ut was still yummy. Perfect for a busy working mom that has little time to prep for dinner during the week.
YAY! So happy to hear it’s been a hit 🙂
It was very good. The whole family liked it very much.
