These bison and mushroom stuffed peppers contain lean ground bison, meaty mushrooms, and chewy rice to create a hearty, satisfying twist on a comfort food classic.

Serving bison and mushroom stuffed peppers.

We didn’t grow up eating stuffed peppers, but my Middle Eastern relatives have been stuffing vegetables for years. My all time favorite is Lebanese Stuffed Kusa Squash but I’m also a huge fan of Stuffed Eggplant with Beef and Pine Nuts, Stuffed Cabbage Rolls and Meat Stuffed Grape Leaves. (Are grape leaves a vegetable?)

Anyway, my husband recently requested stuffed peppers so I decided to create a meaty, protein-packed stuffing. We had ground bison on hand (my newest obsession), some leftover cooked rice, and mushrooms. If you’ve never tried ground bison, it tastes just like ground beef (much more so than ground turkey), but it has fewer calories and less saturated fat and cholesterol per serving. 

Ingredients

Ingredients for bison and mushroom stuffed peppers
  • Peppers: I like to use red bell peppers as they are naturally the sweetest, but I’ll use yellow or orange peppers as well.
  • Onion: Diced white onion gives some flavor while not being too strong.
  • Carrot: Adds texture to the filling as well as nutrients and a bit of a sweet taste.
  • Garlic: Pungent, aromatic flavor that sweetens as it cooks with the meat.
  • Ground bison: A wonderfully lean, yet flavorful alternative to ground beef.
  • Mushrooms: Mushrooms absorb the flavors of the ingredients around them, and have a great chewy texture.
  • Oregano: Strong, earthy, and somewhat minty flavor.
  • Thyme: Savory, somewhat peppery taste that pairs well with oregano and other Itlian herbs.
  • Worcestershire sauce: Adds flavor to the sauce in the filling, and a wonderufl umami taste.
  • Mustard: Whole grain mustard adds a depth of flavor to the filling.
  • Chili flakes: Just a little kick of heat that isn’t overbearing for the dish.
  • Tomato paste: Helps to thicken the sauce a bit, and blends well with the tomato sauce.
  • Tomato sauce: The base of the sauce for the filling, a little tangy and acidic.
  • Rice: I love using already cooked, leftover rice for this recipe, or leftover farro or bulgur wheat.
  • Parmesan cheese: Nutty, salty, and melts to be stringy and delicious.

How to Make Bison and Mushroom Stuffed Peppers

Liz cutting up a carrot

Start your bison and mushroom stuffed peppers by dicing your carrot and onion, and halving coring your bell peppers.

Cooking veggies in pan

Then in a bit of oil or a pan with cooking spray, saute the onion and carrot until they start to soften.

Adding ground bison to pan

Then add the grated or minced garlic along with the ground bison. Break up the bison as it cooks into smaller bits.

Adding mushrooms to pan

Once the bison is mostly browned, add the sliced mushrooms along with the spices (oregano, thyme, Worcestershire sauce, mustard, and chili flakes).

Adding tomato sauce to pan

Season with some salt and black pepper, and once the mushrooms have lost most of their moisture, add the tomato paste and tomato sauce, stirring and mixing to coat the meat.

Adding rice to pan

Add your cooked rice or farro and mix in until heated through.

Stirring bison and mushroom mixture together

With your filling finished, take heaping half cups worth and fill the halves of your red peppers. Sprinkle each filled pepper half with parmesan cheese, cover with foil, and then toss in the oven at 350 for about 30 minutes.

Topping stuffed peppers with herbs

Once parmesan cheese has melted and peppers are softened, remove from the oven and garnish with fresh parsley.

Easy Substitutions

  • Switch the grain. Farro is another favorite of mine for stuffed peppers, but you can use any kind of rice, quinoa, or even bulgur wheat!
  • Change the protein. Ground turkey is another great low calorie option, but regular ground beef works also. Or make them vegan or vegetarian and don’t use meat at all, use lentils or beans!

Frequently Asked Questions

Do you have to boil peppers before stuffing them?

Some recipes will have you boil them, I personally don’t! I like to stuff them and then bake them in the oven. It’s makes them tender and a little bit crisp around the edges. Delicious!

What is the best pepper to stuff?

Most commonly people will use bell peppers, but there are definitely recipes for other kinds of stuffed peppers.

How do you store leftover stuffed peppers?

Keep in an airtight container in the fridge for up to 4 days.

Lean ground bison, meaty mushrooms and chewy farro create this hearty, satisfying twist on a comfort food classic.
PREP: 30 minutes
COOK: 40 minutes
TOTAL: 1 hour 10 minutes
Servings4

Ingredients
 

  • 4 red peppers (halved & seeds and stem removed)
  • 1 medium onion (diced)
  • 1 carrot (diced)
  • 3 cloves garlic (grated)
  • 20 ounces ground bison ((or beef turkey, etc.))
  • 2 cups sliced mushrooms
  • 2 tablespoons dried oregano
  • 1 tablespoon dried thyme
  • 1 tablespoon Worcestershire sauce
  • 1 tablespoon whole grain mustard
  • 1 teaspoon salt
  • ½ teaspoon chili flakes
  • 2 tablespoons tomato paste
  • 14 ounce can tomato sauce (low sodium)
  • 1 cup cooked rice ((or farro, bulgur, spelt, etc.))
  • ½ cup shredded parmesan cheese
  • fresh parsley (minced – optional garnish)

Instructions
 

  • Pre-heat oven to 350 degrees and place red pepper halves in a large glass baking dish; set aside.
  • Heat a large sauté pan over medium heat. Spray with cooking spray and add diced onion and carrot. Cook onion until softened, 3-4 minutes.
  • Add grated garlic to the pan and heat 30 seconds before adding ground bison. Bump heat up to medium-high and brown the bison while breaking it down with a wooden spoon. While bison is browning, throw in the mushrooms and spices (oregano through chili flakes.)
  • Once mushrooms have lost most of their moisture and bison is nicely browned and starting to form a crust (after about 10 minutes), stir in the tomato paste. Use wooden spoon to help incorporate paste into the meat mixture.
  • Pour in the tomato sauce and cooked rice. Stir to combine and cook for an additional 2-3 minutes until mixture is warmed through. Check for seasoning and adjust accordingly before removing pan from the heat.
  • Fill each pepper half with a heaping half cup of the bison and rice mixture. If there is leftover mixture simply add it to the pan around the peppers.
  • Sprinkle a tablespoon of shredded parmesan on top of each stuffed pepper. Cover pan with foil and bake until peppers are soft, about 30-40 minutes.
  • Optional: Once peppers are cooked, remove foil from the pan and broil peppers for 30-60 seconds to brown the cheese and form a bubbly crust on top.
  • Garnish with freshly minced parsley to serve.

    Is the nutritional value based on 1 whole bell pepper or half? Trying to count macros.

    WOW. I tried this recipe. I had both mushrooms and Bison in my fridge and this is the recipe that came up. I normally don’t even follow recipes. I get distracted and improvise. But I tried this one and am so happy I did. Thank you so much!! I used this recipe while I had company over. They were so happy. I served the majority of the farro as a side and paired with corn bread and broccoli. The whole dish is as earthy and perfect. Pact full of taste. Thank you again! I will definitely be making this again!

    Hey Liz,

    When is the whole-grain mustard incorporated? It’s in the ingredients, but not the directions. I made it without the mustard and it was still delicious ????.

      Hi Will!! In step three you’re to add everything listed between oregano and chili flakes in the ingredients list. Basically ALL the things. ;) That’s including the mustard. I’m so glad it was still delicious!!

    Does this keep for leftovers well? How would you recommend — I live alone so think I’m only going to make 2 peppers, but obv will only eat one at dinner, so… any recommendations? Make just the bison and don’t combine until ready, maybe?

      Yes they stay good for up to 4 days!!! You could also freeze!

    LOVE Bob’s Red Mill Farro. It’s such a nice change from brown rice/quinoa/brown rice again. And now I’m thinking I need to give ground bison a try. Hope I can find it at my store.

    This sounds amazing! I have a pack of ground bison in my freezer though it may be passed its prime & freezer burnt. (Shame on me, i hate wasting anything!) Alas, i bet venison (in this case, white-tailed deer) meat would be scrumptious in this recipe as well! In our house we eat more venison than farmed meats which is very lean & loaded with fiber. I cant wait to give this recipe a whirl! Yum!

    Bison is a new obsession of ours, too. We recently traveled to our local bison farm and stocked up. The steak is amazing. I’ll be making a roast in the slow cooker this week. Love these peppers!

    I’m in love with this recipe but especially excited by the grape leaves recipe. I was just walking through whole foods the other day thinking what a shame it is that I couldn’t have grape leaves anymore and didn’t think to look up a paleo option! Thanks!

    We use ground bison/buffalo quite frequently too but I haven’t tried stuffing a pepper with it yet. This sounds so tasty + hearty!

      I need to use it more often!! It’s my new favorite!!
