Prep Time 25 minutes
Cook Time 25 minutes
Total Time 50 minutes

Low-Carb Deconstructed Pizza Casserole is a comfort food casserole the whole family will enjoy!

Ingredients

  • 1 can diced tomatoes, well drained ((14.5 oz. can; do not use petite dice tomatoes)
  • 5 links uncooked turkey or pork Italian sausage (19.5 oz.)
  • 2 tsp. + 2 tsp. olive oil
  • 1/2 tsp. dried oregano
  • salt and fresh-ground pepper to taste (I didn't use much salt.)
  • 12 oz. fresh mushrooms, washed and cut into thick slices (I used brown Cremini mushrooms.)
  • 1 1/2 cups grated Mozzarella cheese
  • 15 slices pepperoni, cut in half (I used regular pepperoni, but you can use turkey pepperoni if you prefer)

Instructions

  1. Preheat oven to 400F/200C.
  2. Spray an 8 inch x 11 inch glass casserole dish with non-stick spray or olive oil.
  3. Pour the diced tomatoes into a colander placed in the sink and rinse with cold water. Let tomatoes drain a minute or two, then spread them out on paper towels to dry (or blot dry with another paper towel on top.)
  4. While tomatoes dry, heat 2 tsp. olive oil in a large non-stick frying pan, squeeze the sausage out of the casing, and cook sausage over medium-high heat until it's nicely browned, breaking it apart as it cooks. (I use an old-fashioned potato masher (affiliate link) to break the sausage apart.)
  5. While sausage cooks, wash mushrooms, pat dry, and slice into thick slices.
  6. When the sausage is done make a layer of sausage in the bottom of the casserole dish and top with the drained tomatoes, spreading them out over the top of the sausage.
  7. Season with dried oregano, salt, and fresh-ground black pepper. (I didn't use much salt.)
  8. Rinse out the pan if needed, then heat the other 2 tsp. of olive oil over medium-high heat. When the pan is hot add the mushrooms and cook, stirring a few times, until all the liquid is released and the mushrooms are starting to brown.
  9. Layer the mushrooms over the sausage-tomato mixture.
  10. Cut pepperoni in half.
  11. Sprinkle the grated Mozzarella over the top of the casserole and lay the pepperoni pieces on top of the cheese, spacing them evenly so the whole top is covered with pepperoni.
  12. Bake about 25 minutes, or until the cheese is melted and starting to brown. Serve hot.

Notes

I used my favorite turkey Italian sausage for this recipe; use pork sausage if you prefer.

  1. I made this last night for Pizza night so I wouldn’t feel left out. Instead, there was leftover pizza! Everyone loved it! Thanks!
    Btw- it made a very tasty breakfast this morning too!

  2. I have made this so many times. It is a huge hit in our house. So yummy!

  3. Trying this tonight, it looks great. Doing it ahead with a cook time of 20 minutes so it can be warmed in the microwave when we get home. I felt I was a bit short on browned sausage in the bottom so tossed in a little riced cauliflower to fill it. Will see how that works, I did not have time to down it.. Will let you know.

  5. This was delicious!! I added onions and garlic with the mushrooms. This is our new pizza night! 

  6. No garlic? Isn’t that sacrilege? 🤔😆

  7. Made this today for dinner. Turned out so well and was very filling! It is hard to find ideas that allow me to eat keto and feed a picky hubby😉 Had a yellow tomato from my garden😋 a perfect addition. Now I am going to have to make 2 so I can add some fresh veggies😁

  9. Say I don’t have an 8×11 dish, only a 13×9… Should I cook at the same temperature and just keep an eye on it? Increase the amount of ingredients? Any thoughts?

    • I’m guessing it will still work, probably cook a bit more quickly since the mixture will be thinner. If you had more sausage it wouldn’t hurt to increase that a little. You might want to increase the cheese too. Hope that helps; let me know how it goes.

      • It ended up turning out great!

        I did add about 25% more sausage…based on some rough math. And did closer to 2 cups of the cheese.

        For timing, I followed the original instructions and then moved under the broiler for a few additional minutes.

        Turned out delicious! Will make again and again!

    • Happy to hear that it worked well and you enjoyed it so much!

  11. I made this today, but I did it a little different. I used all the ingredients and put them in the order you did, but I’m the only one eating healthy in my family and I can’t eat all that alone. So I cooked them in the same layers using a muffin pan, and released them from the edges, let them cool and now there in the freezer except the one I ate lol. After they freeze I will package them and then I’ll have them on hand when I’m craving pizza. Hopefully they freeze well but if not I’ll know for next time. One thing I did wrong was to bake as directed, the instructions was for a whole casserole so I should have cut the cooking time down for cupcake size. The cheese on top was a little hard but that’s my fault. They were amazing and I plan on adding this to my rotation and maybe eventually making a whole one to share with the family. If you weren’t told it was healthy you would know by the taste. Thank you for the amazing recipe!!

  12. This is a wonderful idea. I have tried to make many substitute crusts. They were awful. What we want is the sausage, pepperoni, cheese, vegs, etc….

    This provides all the good stuff..

    thanks for the recipe.

  13. The pin for the last picture before recipe links to the recipe for pepperoni pizza chicken bake, not this one. though picture is correct.

    • I am not 100% sure what you mean. But if you clicked on a PIN on Pinterest that had a photo of this recipe but went to the Pepperoni Pizza Chicken Bake I can guess what happened. When someone clicks the pin icon on my site, they get all the photos on this page that they can pin. That includes the popular posts in the sidebar, and this post is one of them. So if someone clicked on that photo and pinned, the PIN would link to the post it was on at that time, apparently the pizza chicken one. Unfortunately there’s nothing I can do about that kind of random pinning!

      • I added a bit of onion and green pepper, and had shitake mushrooms (I could afford the carbs today) It was delicious. I look forward to trying your other recipes. 

    • So glad you enjoyed it!

  14. So glad you enjoyed it!
