Ingredients in Keto Philly Cheesesteak Stuffed Peppers
Ingredient Notes
- Green bell peppers: For this recipe I used green bell peppers as that is what you typically see on a Philly cheesesteak sandwich, but you can use any color pepper you prefer. (Try the Philly Cheesesteak Casserole from my book Craveable Keto)
- Provolone cheese: Melty provolone is always my first choice for this recipe, but you can use any cheese you prefer. I also love sharp white cheddar, American, smoked Gouda, and havarti. I like to live on the edge and mess with tradition.
- Roast beef: I used a thinly sliced deli-style roast beef. I know this will upset some of the diehard Philly fans, but it's delicious. A true Philly is made with thinly sliced ribeye steak. (I get all my grass-fed beef here)
- Mushrooms: I used baby bella mushrooms for this recipe, but you can use any mushrooms you prefer.
- Onions: The longer you cook the onions, the sweeter and more caramelized they will be. The sweetness complements the bitterness of the green peppers nicely.
Step By Step Instructions
How to make Philly Cheesesteak Stuffed Peppers
STEP 1: Preheat oven to 400°F. Slice peppers in half lengthwise, remove ribs and seeds.
STEP 2: In a large sauté pan over medium-low heat, add the butter, olive oil, garlic, mushrooms onions and a little salt and pepper.
STEP 3: Sauté until onions and mushroom are tender and they start to caramelize.
STEP 4: Line the inside of each pepper with a slice of provolone cheese.
STEP 5: Slice the roast beef into thin strips and add to the onion and mushroom mixture. Allow to cook 5 to 10 minutes.
STEP 6: Fill each pepper with the meat mixture until they are nearly overflowing.
STEP 7: Top each pepper with another slice of provolone cheese.
STEP 8: 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)
Recipe Tips and Variations
- Storage: Store leftovers in the refrigerator for up to 3 days. (These are my favorite meal prep and storage containers)
- 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. (Try these Sloppy Joe Stuffed Peppers)
- 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.
- Make stuffed mushrooms: If you are not a fan of bell peppers, or just want a little variety, try stuffing the meat and veggie mixture inside portobello mushroom caps instead of peppers. (check out these keto stuffed mushroom recipes)
- Add pickled peppers: I like to add some sliced pepperoncinis to the top of these Philly Cheesesteak Stuffed Peppers after cooking.
- Mix in some mayo: Mix some mayo into the stuffing mixture, or just dip your peppers in mayo for some extra creamy goodness. Try my Homemade Roasted Garlic Mayonnaise Recipe.
Frequently Asked Questions
This depends who you ask, but a traditional Philly is a crusty hoagie roll, thinly sliced ribeye steak, grilled onions and either Cheez Whiz or American cheese.
If you are not a fan of green bell peppers, you can substitute orange, yellow, or red bell peppers. They are milder and sweeter.

I did bake the peppers first to soften them but everything was perfect just the way the recipe was written. I have never been disappointed by a recipe from Kyndra.
Eliza Cespedes says
I thought this recipe was remarkable, Very tasty and filling.
Andrea says
My husband loved it, said it's in the top 10. I seasoned the bell pepper & baked them a little bit before stuffing. Here's a good tip... surprisingly the steak's really easy to slice thin when it's semi-frozen.
Kathryn says
Love this recipe! It's quick to put together and it makes great lunches throughout the week. I put a small amount of cream cheese in mine because, well, I have an addiction to cream cheese!
Beth says
These are great! I made last night. Definitely recommend baking the peppers for the extra 10 minutes before filling them. I used shaved beef- worked perfectly!
Karen Parisi says
This is a family favourite in our house!!!

Becks says
Thank you for the excellent recipe, I put a little cream cheese in with the meat mixture and I kept it low carb but it turned out creamy inside and delicious.
