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!


  • 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)


  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.


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

  1. This was absolutely delicious – I made it with ground beef (I don't like sausage) but loaded it with Italian seasoning, and bought Italian Style diced tomatoes so that helped. I also added a little bit of Boboli pizza sauce for some extra flavor.

    As a newly-diagnosed diabetic, I've been CRAVING pizza and went looking for recipes when I was just ready to bake some mozz and sauce and pepperoni and eat it with a spoon. Thank you for having an alternative!

  2. This was really good. One of the hardest things for me on South Beach is giving up pizza. Making "pizza" with some vegetable as the base doesn't quite work for me, and making cauliflower crust seems like too much effort. This was easy, and I got all the flavors I'd been craving. Thank you!

  3. Can this be made the day before, then heated up the next day for lunch?

  4. Thank you! This was sooo good!

  5. I made this last night and added whole grain spaghetti to the bottom for an extra twist and it turned out fantastic! I do not have a place big enough for an oven, since I live in Japan, but I used my toaster oven and it cut the cooking time in half, which was even better! Great recipe! Super easy to make and I will definitely make it again. Thank you!

  6. What about using ground sausage instead of links? Maybe adding some onion, thinking purple onion?

    • I squeezed the sausage out of the links to cook it, so it was ground sausage. The ground turkey Italian sausage that come in packages would also be great, and definitely add red onion too if you like.

  7. Hi there. I'm Sheri. Will be making this for the 2nd time tonight. We are eating low-carb and this really satisfied my craving for pizza. Now if you can just come up with something to satisfy my need for cheese enchiladas, rice and beans….

  8. This recipe is a life saver! I have Gestational Diabetes and was craving pizza. But was told the sauce and crust was not good for me. My favorite happens to be pepperoni with Mushrooms. I made this, and it squashed the craving. My numbers were good too! I might have to make this a few more times. My 3 year old and hubby love it too. Thank you so much for this!

    • SO glad it worked for your blood sugar and that you enjoyed it! Good luck with the pregnancy. Mu niece had gestational diabetes but now she has a beautiful baby girl; hang in there!

  9. Does this recipe freeze well after being cooked?

  10. Kalyn, I just made this after I had a pizza craving and it was delicious! I added onions and peppers and served it with zucchini noodles. Perfect! Thank you so much!

  11. I am a pizza lover but had weight loss surgery nearly a year ago. Someone shared this recipe with me tonight and can't wait to try it! Thank you!

  12. . I'm low carb and gluten-free. Nice to have a pizza like substitute to satisfying a craving.

  13. This was just ok, I think regular turkey sausage should work, and more than just one can of tomatoes. I think next time I'll add more toppings and use a sauce instead. But thank you for the foundational recipe!

  14. Made this tonight without mushrooms but with bell pepper and onion, and a mix of ground beef and chicken Italian sausage, with a few shakes of crushed red pepper and some sliced green onions to finish. Wonderful!! When we're not feeling so carb-conscious, I would definitely serve this over corkscrew pasta. Appreciate this versatile recipe. Thanks, Kalyn!

  15. I have this in the oven now! Used ground turkey for the base meat, thought I had turkey pepperoni but the boyfriend must have ate it all! So deconstructed cheese pizza it is 😉

  16. Just made this tonight with a few changes and it was so good!! I used trader joes refrigerated pizza sauce instead of diced tomatoes, I did cook it down a little before adding it, and I would definitely use turkey pepperoni next time there was a little too much grease with regular pepperoni. I added onions, green peppers and black olives to the mix, and I used a mix of mozzarella and trader joes quarto formaggio mix. It definitely satisfied my craving for pizza (better than anything else I've tried) Thanks for such a great recipe!

  17. Kim so glad you enjoyed it. I don't calculate nutritional information (too hard to do it accurately and I already spend 8-10 hours on each recipe). But if you look in the post where it says "Nutritional Information" I have two suggestions for how you can get that information if you need it.

  18. This is absolutely delicious, I put mine on top a lay of baby spinach.

  19. Can't wait to feature this on my Friday Five list tomorrow! 🙂

  20. Does this freeze well?
