Units Scale

(Order the Groceries to Make this HERE)

  • 8 ounces thinly sliced roast beef
  • 8 slices provolone cheese
  • 2 large green bell peppers
  • 1 medium sweet onion, sliced
  • 6 ounces baby bella mushrooms, sliced
  • 2 tablespoons butter
  • 2 tablespoons olive oil (I use this brand) code kyndraholley for $5 off
  • 3 cloves garlic, minced
  • sea salt and black pepper, to taste


  1. Preheat oven to 400°F. Slice peppers in half lengthwise, remove ribs and seeds.
  2. In a large sauté pan over medium-low heat, add the butter, olive oil, garlic, mushrooms onions and a little salt and pepper. Sauté until onions and mushroom are tender and they start to caramelize.
  3. Slice the roast beef into thin strips and add to the onion and mushroom mixture. Allow to cook 5 to 10 minutes. Line the inside of each pepper with a slice of provolone cheese. Fill each pepper with the meat mixture until they are nearly overflowing.
  4. Top each pepper with another slice of provolone cheese.
  5. Bake for 15 to 20 minutes until the cheese on top is golden brown. (You may want to pre-bake the peppers for about 10 minutes while the meat mixture is cooking if you like a softer pepper)


  • Storage: Store leftovers in the refrigerator for up to 3 days.
  • Reheating: I recommend reheating these Keto Philly Cheesesteaks in the oven or in an air fryer.
  • Make a Keto Philly Cheesesteak Sandwich: To make a more traditional sandwich, cut up the peppers and sauté them with the meat and vegetable mixture. Then pile it all on one of these Keto Everything Buns.
  • Bell Peppers: Make it a rainbow of color and use one red, one orange, one yellow and one green bell pepper. 
  • Beef it up: Instead of the thinly sliced roast beef, use ribeye, top sirloin, new york, or filet mignon.
  • Change the cheese: You will find a lot of debate over what constitutes a true Philly Cheesesteak sandwich. But among the most common variations you will see cheese whiz, provolone, American and sometimes even Swiss.
