I first made this Sausage, Peppers, and Mushrooms Low-Carb Cheesy Bake several years ago during January when easy carb-conscious meals were what everyone was looking for. It was almost an immediate hit on the blog and this is also one of my personal favorites as well, making it perfect to spotlight for a Friday Favorites pick! And when I decided to feature the recipe again it sounded so tasty that recently I made it again and took some slightly-improved photos. Kara and I had fun trying to match the styling of the photo to the earlier pics (which you can see all over Pinterest) while making the food look even tastier than it did in the earlier photos.

And this recipe is so easy, so quick, and so delicious that it’s perfect for a low carb dinner any time of year, but it’s also red and green if you like having a dinner with holiday colors!  If you like Italian sausage and peppers and cheese, I bet you’ll love this for an easy meal.

How to make Sausage, Peppers, and Mushrooms Low-Carb Cheesy Bake:

(Scroll down for complete printable recipe plus nutritional information.)

  1. I liked this best with a whole pound of brown Cremini mushrooms.  Saute mushrooms in a little olive oil.
  2. While you’re cooking the mushrooms, brown the turkey Italian sausage in a different pan. 
  3. When mushrooms are cooked layer than in the bottom of a large baking dish.
  4. Then saute red and green pepper strips until they’re barely starting to soften and layer them over the mushrooms in the baking dish. 
  5. Season the peppers and mushrooms with spices and black pepper.
  6. When sausage is brown, cut into half-slices and brown again on the cut sides. 
  7. Add a layer of sausage in the baking dish.
  8. Sprinkle with a generous amount of grated Mozzarella cheese.
  9. Bake at 375F/190C about 25 minutes, or until the dish is bubbling hot and the cheese is melted and nicely browned. 
  10. Serve hot and enjoy! This will stay good in the fridge for several days and it reheats well. I also heard recently from a reader named Carol who says she freezes it and it is just as good after it’s been frozen!

Sausage, Peppers, and Mushrooms Low-Carb Cheesy Bake

Yield 6 servings
Prep Time 25 minutes
Cook Time 25 minutes
Total Time 50 minutes

Sausage, Peppers, and Mushrooms Low-Carb Cheesy Bake is easy and delicious for a quick dinner.


  • 2 T olive oil
  • 16 oz. brown Cremini mushrooms, washed and cut in thick slices
  • 19.5 oz hot or mild turkey or pork Italian sausage (see notes)
  • 2 red bell peppers, cut into thick strips
  • 2 green bell peppers, cut into thick strips
  • 1/2 tsp. Italian herb blend
  • 1/2 tsp. Spike Seasoning (or use any all-purpose seasoning blend if you don’t have Spike.)
  • fresh-ground black pepper to taste
  • 1 1/2 cups grated Mozzarella (more or less as desired)


  1. Preheat oven to 375F/190C.  Spray a large baking dish with non-stick spray or olive oil.
  2. Wash mushrooms and cut into thick slices.  Heat a little olive oil and saute the mushrooms.
  3. Heat a little olive oil in another large non-stick pan and start brown the sausage over medium-high heat, turning occasionally to brown on all sides.  (If you’re using pre-cooked sausage you can skip this step and just cut sausage before you brown it.)
  4. When mushrooms have released their liquid, liquid is evaporated, and mushrooms are lightly browned, transfer mushrooms to the bottom of the baking dish.
  5. Trim away stem and seeds of peppers and cut into thick strips.Heat about 2 tsp. more olive oil in the same pan you cooked the mushrooms in and saute peppers over medium high heat just until they’re starting to soften, about 4 minutes.  (They will cook more in the oven, so don’t overcook if you prefer them slightly crisp in the finished dish.)
  6. Layer the peppers over the mushrooms in the baking dish. Season the peppers and mushrooms with Italian Herb Blend, Spike Seasoning, and black pepper.
  7. When the sausage is lightly browned on all sides, remove to a cutting board and let cool enough to slice.  Then cut sausage in half lengthwise, cut into thick half-slices, reheat the pan, and brown the sausage again on the cut sides.
  8. Layer the browned sausage over the mushrooms and peppers and sprinkle with desired amount of grated mozzarella.
  9. Bake about 25 minutes, or until all ingredients are sizzling hot and the cheese is melted and nicely browned.
  10. Serve hot.


I used Jenni-O Hot Italian Turkey Sausage for this recipe which is low in carbs and gluten-free. Use pork sausage if you prefer more fat. Leftovers of this can be kept in the fridge for a day or two and reheated in a toaster oven or in the microwave.

  1. Made this recipe as written and it turned out fantastic. Very tasty! I was glad I had Spike seasoning on hand. I debated on skipping the sautéing of the peppers and mushrooms before putting in the dish, but I am glad I didn’t as it turned out perfectly! I put a few more sausage links than called for so we have lunches for work tomorrow, excited to eat it again!

  2. I didn’t see where to add the Italian and Spike seasoning. So i just kind of layered it into the dish. Very yummy though, Thanks!

    • Hi Jennifer. It does say this, “Season the peppers and mushrooms with spices and black pepper.” but maybe I need to mention them specifically. I will edit to fix that. Glad you enjoyed it!

  3. Do you think Goats cheese would work with this instead of mozzarella? I only have goats cheese or cheddar in my fridge.

    • Flavor-wise I think the goats cheese would taste good. But it will melt completely in the oven and won’t hold the dish together like a firmer cheese would. I would probably pick cheddar out of the two options you have.

  4. This was delicious! I was a little dubious thinking it might be lacking without any sauce but it was amazing! Easy to cook, quick and satisfying. So good!
    I did skip a step and cut up the sausage and browned it versus browning whole and cutting and browning more.
    We will make this again for sure!

  5. Kind of horrified that there is no onion in this so I definitely added one! It’s the 1/2 Italian in me! Looks and smells delish!

  6. would like the nutrition facts.  How many carbs, fiber and fat?  

  7. I added cilantro!

  9. Made this tonight and I haven’t had much luck with Keto low carb meals for taste. We loved this. I added onions with the peppers and a layer of baby spinach (could use more if wish), plus I may add cauliflower next time as well. I had honey garlic sausages so used those. Very tasty!
    Do you know how many carbs in this recipe?

  10. I saw at the bottom of the recipe that this will keep for up to two days in the fridge for leftovers. I was wondering if it would keep for five days? I like to cook my meals on Sunday and then eat them throughout the week since I’m a very busy college student. Thanks!

  11. There isn't anywhere in the printable recipe that says to chop sausage up into chunks after browning.. i just put the half links into the pan.. maybe add that for Pinterest? It's in the oven now.. we'll see how it goes!

    • So sorry; I can't figure out how that happened because I copy the recipe and post it with no photos to make the printable recipe, but obviously I messed up somewhere. I just fixed the printer-friendly recipe; thanks for telling me!

  12. I really love this post having so much in one blog.. Really a visual treat.

  13. This is tasty. I will make it again. I might swap onions for the mushrooms or add them in as extras. This would be really good on tortillas but, alas, I'm trying to cut my carbs. Thanks!

  14. Thanks so much; I will fix it right now!

  15. We LOVE everything in this recipe, so I'm sure it will be a hit with my family. I like Lydia's (The Perfect Panty) idea of pouring beaten eggs on top, before baking. I've set aside one evening a week (Tuesdays) when we have 'breakfast for supper', so we'll definitely enjoy this dish then. I'll serve it with buttered whole wheat English muffins, OJ, and coffee. We like to have a 'light' dessert (or snack) later in the evening while watching TV. Thanks so much for a terrific recipe!

  16. I love mushrooms, I love peppers, and I LOVE sausages…this is definitely my ideal casserole!

  17. This sounds absolutely delicious! I'm a huge fan of turkey sausage, which I definitely think is just as satisfying and tasty (in some ways even more so!) as regular, full-fat pork and beef sausages. Mmmmmmm … and I love the addition of cremini mushrooms in with the peppers – great idea! Such a lovely, flavorful, healthy and easy dinner! And I have to smile at your explanation of being a "bad blogger" 😀 – I have so, so many recipes that are just awaiting the right season to be unveiled and published (or … ahem … waiting for me to remember or unearth them from the depths of my folders and notebooks)! ~Shelley

  18. Who could resist sausage and peppers? I might even pour some beaten eggs over this and turn it into a breakfast casserole!
