Philly Cheesesteak Stuffed Peppers


Ingredients and substitutions:

  • Bell Peppers: You need green peppers to stuff, and red to fill (and for some color). Feel free to use any color bell pepper though!
  • Mushrooms: Use packaged pre-sliced button mushrooms but you can use any type of mushroom.
  • Steak: Sirloin is the recommendation. It’s a nice, lean cut with good texture and flavor. Go for a steak that’s about 1″ thick; alternatively, you can use ground beef, ground turkey, chicken breast, or any other type of protein.
  • Onion: Red is the way to go here! It’s nice and crunchy and adds a pop of color but any type of onion will work.
  • Cheese: Mozzarella is the best cheese to use in this recipe, but Swiss works great too.

Ingredient add-ins:

  • Add in some chopped chili peppers (jalapeno, poblano, or anaheim peppers are great!) for a little heat.
  • Add some cherry tomato halves and oregano for an Italian twist.
  • Swap the red for yellow onion for a little more sweetness.

What to serve with stuffed peppers?

Some crispy roasted potatoes are the perfect companion for the peppers! Cube them, oil them up, and season them before tossing them in the oven with the empty green pepper halves. Then they’ll all finish up together!

Storing & reheating:

You can assemble the peppers the day before and keep them in the fridge before their final bake. Just add ten minutes to the baking time.

For storing leftovers, keep them in the fridge in some Glass meal prep bowls for 3-5 days. Reheat them in the microwave until heated in the center. You can also reheat them in a baking dish covered with aluminum foil at 375F for 30 minutes.
