Pizza Casserole Keto Friendly

I love pizza. I mean, I love it. Pizza for dinner last night? No problem, I’ll eat pizza for dinner again tonight. So, when we started following a keto lifestyle, I was a little concerned because completely giving up pizza made me feel sad. Yes, I love it that much. So, one of the very first recipes I started looking for was an easy pizza recipe.

I had already tried several different cauliflower crusts, and my family is just not sold on such an atrocity. Maybe there are better recipes for a fabulous cauliflower crust. However, I haven’t found it yet. I came up with the perfect Keto Pizza Casserole without cauliflower. It’s easy to make, satisfying, and tastes like a smorgasbord of deliciousness.

Ingredients You’ll Need to Make This Delicious Low Carb Pizza Casserole

  • Deli Ham – I prefer using either the smoked or black forest deli ham. You want to avoid honey ham due to the added carbs. It should be sliced thin, but not too thin.
  • Marinara Sauce – Make sure to choose the lower-carb version of marinara sauce. If you don’t have a favorite brand already, this low-carb Marinara sauce is a good choice at only 4g net carbs per serving. 
  • Ground BeefChoose your favorite type of ground beef for this recipe. 
  • Mozzarella Cheese – Mozzarella cheese makes a pizza! I usually buy a block and grate it myself if I have time. But pre-grated is fine too if you need to save some time. (Those that eat keto avoid pre-grated cheese as it contains fillers to keep the cheese separated that contain added carbs.) 
  • Parmesan Cheese –  Make sure to purchase freshly grated parmesan cheese and not the canned variety. (You’ll want to buy a block to grate yourself see the note above.)
  • Italian Seasoning and Oregano – Add an added dimension of flavor to this already delicious recipe.  
  • Pepperoni – You’ll want to get the regular-sized pepperoni for this recipe and not the minis as they will be the pizza topper.

Directions for the Keto Pizza Casserole

For the full, printable recipe for Keto pizza casserole, scroll to the bottom of the page. I also include the visual process for those who might find it helpful. I am sure you will enjoy this as much as we do!

Bottom layer of a keto pizza casserole

Step 1: The first three layers of the keto pizza casserole are deli ham, low carb marinara sauce, and browned ground beef. Start by browning the ground beef. Once it is browned, add in the sugar-free, low-carb marinara sauce and seasonings. Let this cook on medium-high for about five minutes.

Next, it’s time to start assembling the casserole. Spray a 9 x13 casserole dish with cooking spray and then cover the bottom of the dish with ham. They will probably overlap a little bit, and that’s okay. Add just half of the marinara and beef mixture on top of the ham.

Tip: If you keep ground beef already browned in the freezer, you can put this casserole together in less than 10 minutes. If you don’t like ground beef, you can sub turkey or ground Italian sausage instead. 

Adding the cheese to keta pizza casserole

Step 2: It’s time to start adding the cheese. I love how the layers come together to make a delicious casserole that tastes amazing and curbs my craving for pizza.

Top layer of deli ham

Step 3: You’ll add a second layer of ham. If you prefer, you could use turkey, salami, or large deli sized pepperonis instead.

Adding more layers to the pizza casserole

Step 4: Continue the second layer by adding ground beef with marinara sauce and the cheese on top. This time you will top it off with your pepperoni.

Placing cheese and pepperoni on the casserole

Step 5: Bake in a 350-degree oven for 20 minutes. Then move the casserole dish to the top rack and turn the oven on broil. It will only take 1 to 3 minutes for the cheese to lightly brown on top. Watch it closely, so it doesn’t burn.

I love to sprinkle fresh parsley on top. It makes it seem fancier than just a casserole.

Finishing up with a bite of keto friendly pizza casserole

Can this recipe be made ahead of time?

Sure, you can assemble this recipe and pop it in the fridge to bake later. You will likely need to bake a little longer since it is coming out of the fridge.

Why do I need to use sugar-free marinara sauce?

Sugar is often hidden in store-bought sauces like marinara. Make sure to look for a marinara sauce with no added sugar in the ingredient list. You will see carbs and sugar listed on the nutritional information, but it is from the natural sugars in tomatoes, and it is minimal. 

Here is a great list of low carb marinara sauces and the net carb count for each: 

  • Rao’s Homemade Marinara Sauce – 4g net carbs per ½ cup
  • Rao’s Homemade Tomato Basil Sauce – 3g net carbs per ½ cup
  • Lucini Italia Organic Tuscan Marinara Sauce – 3g net carbs per ½ cup
  • Lucini Italia Organic Rustic Tomato Basil – 3g net carbs per ½ cup
  • Mezzetta Napa Valley Homemade Sauce Marinara – 6g net carbs per ½ cup
  • ALDI Simply Selected Premium Marinara – 5g net carbs per ½ cup
  • Keto Marinara Pasta Sauce by Yo Mama’s Foods – 4g net carbs per 1/2 cup

Variations to this recipe:

I made this keto pizza casserole with ham as the base layer, much like a pizza lasagna. If you don’t like ham, you could use turkey instead or omit it.

  1. So I’m knew to Keto. If you were going to only eat this as a meal, how much could you eat? Since it is considered 8 servings, is 1 serving all you should eat?

    1. I personally eat until I am satisfied. It is a very filling meal. I make a nice salad to eat with it.

    1. Whatever you prefer. Feel free to customize to your personal preferences. I’ve only made it as is.

    1. Hey, Beth, I have only tried with Ham. Not sure what other meats you enjoy and would work with the flavors of the pizza casserole.

  2. Made this tonite and it was outstanding! Eight servings is stretching it a bit. Six seems more feasiblle. I would definitely make again.

  3. So good! Followed your recipe. So I’m assuming the video is not made by you, correct? LOL! Just curious, since the video is different than the recipe.

    1. You’re right. I didn’t do the video myself. I could have even updated the recipe since the video was made. I’m glad you enjoyed the casserole. It’s one of our favorites!

    1. 5 stars
      Wondering if anyone has tried anything else other than lunch meat, or any meat for that matter? New to this keto low carb life, and just trying to figure out a substitute. Thanks! We did love the original recipe as well however.

  4. Hi :-), I’m going to be making this tonight but had a question. I want to add vegetables such as sliced onion, bell peppers, mushrooms and olives. Would the baking time be the same? I don’t want the vegetables to get too soft. Thank you!
