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.

Sounds really good, but we aren’t fans of sausage. Â Could organic, grass-fed lean ground beef be used in its place? Â
Of course you *could* use ground beef. Whether it will be as tasty with the beef, I can’t really say because I haven’t ever made it that way. If you like ground beef on pizza, you’ll probably like it. I’d love to hear what you think if you try it.
Your recipes are enabling me to stick with my keto-low carb diet and I am being successful! Thank you! I am learning to cook again!
So happy to hear that Holly!
This was good but very dry. Did I do something wrong?
Hard for me to say without knowing just what you did or what your definition of dry is, but you can surely not drain the tomatoes if you prefer.
So glad to see this was ordering pizza for rhe family and so wantwd something great. I found this and tried it and it was Awsome . Thanks
So glad you enjoyed it Sebrenia!
Why not petite diced tomatoes?
I used the chunkier diced tomatoes in this to give more structure to the recipe. I worried that the petite dice wouldn’t work the same way but you can try them.
I just popped this in the oven. Can’t wait to taste it. Instead of mushrooms and olives I used fresh jalapeno peppers. Kids not a fan of mushrooms and olives but next time I’ll make it the way my husband and I want it. 😊
Hope you enjoy the spicy version!
It was soooooo good! Definitely gonna be a regular meal in our house. Thank you!
So glad you enjoyed it!
My husband said he would eat this every night! With 3 boys (11,11,13) I made a full 9×11 casserole and it was gone! I upped most of the ingredients to fill the dish. I also made garlic toast for them. Have your tried making this the night before and cooking the next day? Seems like a good one to get the kids to pop in the oven on our busy nights.
So glad to hear it was a hit! Sounds like a challenge feeding all those boys, glad they enjoyed it. I’m sorry but I haven’t made it ahead and refrigerated, then cooked later. It seems like it would work, although I would let it come to room temperature before you bake. I’d love to hear how it goes if you try that, thanks!
I used your recipe as a jumping off point for dinner last night. It was so good! My teen boy balked at a “no crust” pizza, then came back for 3 helpings! I added fresh sautéed spinach and used petite tomatoes that were well drained. I also served with cottage cheese (cold on the side) but it would have been good mixed with the tomatoes for a little more sauce. SO GOOD! I’ll add a lot more spinach next time.
So glad to hear it was a hit, even with the teens! And fun hearing how you adapted the recipe!
I made this for dinner tonight and it was fabulous! I did add 2 layers of thinly sliced zucchini for a little more veg and fiber and some black olives b/c I love ’em on pizza, otherwise followed recipe exactly. Will definitely make this one again! Maybe artichoke hearts next time . . . ?
So glad you enjoyed it! And I love the idea of adding some layers of zucchini; that’s brilliant!
It’s working for me (on iMac desktop). There are so many variables that affect videos and they’re hosted through another company so I’m not really able to troubleshoot. Hope it will start up for you.
That was really really good!!!!
Thank you
So glad you liked it!
Quick question regarding servings… If this was the only thing I made for dinner for two people, would you expect it to stretch two meals based on experience?
I would say yes it could make two meals for two people, but obviously that will depend on who the two people are and how big of eaters they were.
This was so good I did not even miss the crust! Thanks!
So glad you enjoyed it!
I made this 2 nights ago and my hubby said it’s a keeper! The only thing I think I’ll do is add a little bit of pizza sauce/spaghetti sauce with the tomatoes next time. It was a bit dry for our taste, but that’s just us. Love the recipe!
So glad you enjoyed it! Feel free to adapt in any way you prefer!
Oh boy! This looks amazing. I would also add green peppers and some black olives.
Glad you like it. I would love both those additions.
My husband really liked this recipe… I’ve been trying low carb recipes now for 3 months it is hard fo find ones that the husband likes, bit you have created one.. Thank You…
So glad to hear that!
Plus in every recipe I give a link to a place where you can enter the ingredients and it will calculate it for you, in addition to a suggestion to use Yummly, which calculates it (although they are not always 100% accurate.
This is a great idea! Will make something similar. Did you forget to list the garlic and/or onions you used? That would be in any pizza sauce/most Italian dishes. Or are your family allergic to them? It does look nice 🙂 Garlic is essential tho 🙂 Thanks again!
The sausage I used is really flavorful and garlicky, but you can definitely add garlic or onion!
I just want to add my praise to this fantastic recipe! I am thrilled at how well it turned out.
Even my husband – a devoted pizza and carb lover – thought it was delicious. (Though admittedly, he wrapped his servings up in a tortilla. Ha!)
Thanks for creating a recipe both my husband and I can enjoy together 🙂
So glad to hear it worked for and pleased you both!
Looks goodÂ
6 days on Keto 😬 barely.  Just wondering why not petite dice tomatoes (I have those in my pantry)Â
I used the chunkier diced tomatoes in this to give more structure to the recipe. I worried that the petite dice wouldn’t work the same way but you can try them.
