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.

Greg H says
Did these just last night. Very good, and will definitely do again. Would sprinkle some extra shredded cheese throughout the meat nixture next time.
Krista says
This was delicious! Used half garlic, half normal roast beef and would definitely do all garlic next time. Hoping to convert it into a camping recipe by wrapping in foil to put on the bbq so I can make it ahead - mmmm!
Stacey says
Another fantastic Peace, Love, and Low Carb recipe! We made it pretty much exactly as the recipe stated, and it was fantastic and filling! Will definitely be making it again!
Becky says
One of my all time favorite meals, easy to make and delicious. I made this in 2015 and haven’t looked back. My Hubby prefers green peppers and I like to use yellow, orange, or red peppers.
Lisa Rowland says
These are amazing and you won't miss those carbs, delicious and creative...as always. Peace Love and Low Carb never fails!
Suzanne says
You should be able to find organic, grass-fed chip steak at farmer's markets around the country. This will be so much tastier than steak-umms. I like putting the sandwich filling with chopped hot and sweet peppers on top of a salad.
Jessica Foster says
I've been making this recipe of yours for years and it is still one of my favorites. You rock!
Megz says
I male this quite often for the family, one of the first recipes I made from this blog! I add a packet of Italian seasoning mix to my onion mixture and ny husband just loves the extra zest.
