Low-Carb Deconstructed Pizza Casserole
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
- Preheat oven to 400F/200C.
- Spray an 8 inch x 11 inch glass casserole dish with non-stick spray or olive oil.
- 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.)
- 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.)
- While sausage cooks, wash mushrooms, pat dry, and slice into thick slices.
- 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.
- Season with dried oregano, salt, and fresh-ground black pepper. (I didn't use much salt.)
- 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.
- Layer the mushrooms over the sausage-tomato mixture.
- Cut pepperoni in half.
- 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.
- 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.

Loved it! prepared with ground pork sausage. adored by all ! Thanks
Thanks for the nice feedback! So glad you liked it.
Can you make make this ahead of time, then bake it for dinner same day?
Sorry I missed this comment. I moved my site to a new web host, and the site was up but I just realized today that no comments were coming to my e-mail for NINE DAYS, yikes.
Yes, you can do that but if it’s been refrigerated I’d let it come to room temperature before baking.
I only have diced petite tomatoes?
Recommended not to use.
Anyone have a comment on why?
Sorry I missed this comment. I moved my site to a new web host, and the site was up but I just realized today that no comments were coming to my e-mail for NINE DAYS, yikes.
I prefer the more substantial pieces of tomato for this recipe, but I do hope you went ahead and made it with what you had!
So delicious! Didn’t miss the crust st all. Made it exactly as written 👍
So glad you enjoyed!
We finally made this & added red & green bell peppers & black olives to make it “supreme” style. I also mixed a little pizza sauce in with the sausage after it was browned & we just LOVE this! SO good!
Made 2 versions of this casserole tonight, one for my husband and I and one for the grandkids. In theirs I substituted diced ham for the sausage and didn’t add the mushrooms. Added bacon pieces to both, mushrooms and garlic and yellow onion and black olives along with the ham and sausage to ours, and extra cheese to both. Also used pepperoni, mozzarella, and triple cheddar and some shredded parmesan. Will definitely be making this again.
So glad you enjoyed. Sounds like you did well at making a version both groups could enjoy.
Can’t wait to try this!! Any suggestions on what could be substituted for mushrooms? I love them but my husband isn’t a fan.
Hope you enjoy! Maybe just put mushrooms on half of it!
You can substitute or add to almost anything. I added black olives, sauteed onions, & spinach.
This was sooooo good! Perfect for my pizza craving!
Loved this recipe! I added spinach and 1/2 cup of grated parmesan as well. So yummy.
So glad you enjoyed and fun hearing how you switched it up a bit!
Had this tonight for dinner and it was delicious! Definitely will make this again for dinner.
Hi Cassidy, so glad you enjoyed it!
What a simple yet delicious recipe. We made yesterday and enjoyed every bite!
Thanks Kate! So glad you guys enjoyed it. And fun hearing from you too.
Excellent! We’ve been craving pizza for weeks but wanted to stay true to our low carb diet. This is the answer. We substituted hot Italian sausage and added jalapeños to my wife’s side. Baked it on our Traeger in an enameled cast iron skillet at 450 for 25 mins. Yummmmm …..
Glad you enjoyed! I like the idea of “baking” on the Traeger!
I made this last night and it was INCREDIBLE! This is definitely going into the regular rotation. Thank you!!
Thanks Elizabeth, so glad you enjoyed it!
This looks so yummy and I have it in the oven now. Since I am on the Code Red lifestyle regular cheese is not allowed so I grated frozen cream cheese on it. Can’t wait to taste it!
Good idea, hope you enjoy!
This is my carb-loving husband’s FAVORITE low-carb recipe. I make it all the time! I add green bell peppers in with the mushrooms, and it’s *chef’s kiss* PERFECT.
This was delicious. I added a partially sauteed green bell pepper and omitted the mushrooms. Turned out phenomenal! Will definitely be making this again soon.
So glad you enjoyed it!
