Cheesesteak Stromboli is everything you love about classic Philly Cheesesteak Sandwiches except it's all rolled up in frozen dough and baked! This recipe is easy to make and takes ingredients we almost always have on hand!
Thaw bread dough and let rise according to package instructions.
Dice onion, peppers, and mushrooms. Saute in a skillet with 1 Tablespooon of butter.
Preheat oven to 375 degrees. Line a jellyroll pan with parchment paper or spray with nonstick spray.
Roll bread dough out to a 12" x 18" rectangle. It doesn't have to be perfect!
Mix mayonnaise with garlic powder. Spread over rolled out bread leaving an half inch border.
Add a layer of deli roast beef.
Add the onions, peppers, and mushrooms.
Add a layer of cheese.
Roll the stromboli up jelly-roll style. It will be easier to roll up tightly if you used shredded cheese. I used provolone slices and I folded the edges over the middle. It makes a shorter and wider roll, but that's okay! Set it on a baking sheet.
Melt remaining tablespoon of butter. Brush melted butter over the top of the roll. Sprinkle with parsley, garlic seasoning, and sesame seeds if desired.
Bake 15-20 minutes until golden brown and warmed all the way through.
Notes
CHEESE: You can use grated or sliced cheese. Provolone is traditional for Philly Cheese Steak. You can also use processed cheese such as Velveeta.BEEF: I used sliced deli roast beef because it's easy. If you have ribeye or another cut of steak you can slice it thinly and fry it to use.
