Ingredients in Keto Philly Cheesesteak Stuffed Peppers

This recipe for keto cheesesteak stuffed peppers takes its inspiration from traditional Philly cheesesteak sandwiches.  It starts off with thin slices of beef, layers of melty cheese, and sautee vegetables like onions, mushrooms, and bell peppers.  You’ll need:

  • bell peppers
  • sirloin steak
  • olive oil
  • mushrooms
  • red onions
  • seasonings
  • garlic
  • provolone cheese — or choose American for a more “Whiz” taste.

What’s in a Philly Cheesesteak Sandwich?

A cheesesteak — also known as a Philadelphia cheesesteak or a Philly cheesesteak — is a sandwich made from thinly sliced pieces of beefsteak and melted cheese in a long hoagie roll.  As far as the cheese itself, American cheese, Cheez Whiz, and provolone are the most commonly used cheeses.

What steak to use for Philly Cheesesteak?

For a traditional cheesesteak, the meat is usually thinly sliced rib-eye, sirloin, or top round, although other cuts of beef are also used. This recipe uses top sirloin — but just choose whatever looks the best at your market.  And if you really want to make it easy, you can even substitute ground beef to make these stuffed peppers.

How to Make Keto Philly Cheesesteak Stuffed Peppers

What I love about this recipe is that it’s great for make-ahead dinners.  Sure, there are a few pre-cook steps — like searing the meat and chopping the veggies. But a lot of the cooking time is done in the oven. 

It’s easy to make ahead of time, too. You can either prep the whole dish ahead of time and bake when ready, or you can cook the stuffed peppers from start to finish and refrigerate them for meal prep dinners or packed lunches.

To get started, prep your bell peppers but cutting then in half and seeding them. You can use any color bell pepper you like, I went with a combo of green and red — the red, orange and yellow peppers tend to be sweeter than the standard green bell peppers. I also like to bake my peppers to soften them up a bit before I stuff them. You can pop them in the oven with a covering of aluminum foil to help them steam a bit.

While the peppers are softening, I prepare the filling: sliced steak, mushrooms, onions, and peppers. First, I sear the steak well on both sides to develop a flavorful crust.  While the steak rests, I saute the sliced veggies.  After the steak rests, I slice it as thin as possible against the grain.  A sharp knife comes in really handy here!

Then, all that’s left to do is stuff the peppers with the filling, top with cheese, and bake it all together.
