Keto Philly Cheesesteak Stuffed Peppers Recipe: A New Family Favorite

This easy-to-make, Keto friendly and low-carb recipe will quickly become a family favorite. It’s made with sirloin steak instead of ground beef (which you will find in similar recipes) thereby giving it more flavor and making it heartier.

Stuffed peppers are an old family favorite. My mom made hers the Italian way with rice and tomato sauce which were delicious. But I experimented with new flavor profiles and combinations to make this recipe a little healthier and low-carb. Besides, who doesn’t love a Philly Cheesesteak? My family loved this recipe!!

Keto Philly Cheesesteak Stuffed Peppers Recipe Ingredients

Ingredients:

4 whole bell peppers 

1 bell pepper, sliced

1 sirloin steak (about 1 inch thick)

1 8 oz. package of sliced mushrooms

1 sweet onion, sliced

2 garlic cloves, minced

1 cup mozzarella cheese, shredded (substitute with your favorite cheese)

Extra virgin olive oil

Salt and pepper

Directions:

  1. Preheat oven to 400 degrees F. Slice 4 bell peppers in half and remove the seeds and stems. Place the peppers in a 9×13” casserole dish and drizzle them with olive oil. Sprinkle on salt and pepper. Bake for 10 minutes.
  2. While peppers are baking, heat a large skillet on high heat. Pour a thin layer of olive oil in the pan – just enough to coat the bottom. Generously salt and pepper both sides of the sirloin. Place it in the hot skillet for 1 minute on each side. Remove from pan and place the steak on a cutting board. 
  3. Turn the heat down to medium for the same skillet and add the mushrooms and garlic. After 1 minute, add sliced onions and 1 sliced bell pepper (I used ½ of a red and ½ of a green bell pepper). Season with salt and pepper. Cook for 3-4 minutes, stirring occasionally.
  4. While mushroom and pepper mixture is cooking, slice the steak into the thin strips and discard any fat. Add the steak strips to the skillet and stir to combine. 
  5. Turn off the heat to the skillet. Spoon the steak and pepper into each cooked bell pepper half – filling until all halves are full and mixture is used up.
  6. Top with shredded mozzarella cheese and place in the oven to bake for about 15 minutes. Remove from oven and serve warm.

This recipe works well served with cauliflower rice and a green salad.
