Ingredients
- Frozen white bread loaf: thawed fully for a perfectly crisp and golden crust
- Mayonnaise: mixed with garlic powder to add moisture and gentle flavor throughout
- Butter: to enrich the filling and help brown the vegetables and crust
- Green bell pepper: for a pop of color and sweet crunch best when firm and shiny
- Yellow onion: provides savory depth best chosen with dry, crackly skin
- Mushrooms: add earthiness pick firm caps without blemishes
- Deli roast beef: thinly sliced for tender, flavorful meat coverage
- Provolone cheese: melts smoothly delivering creamy richness
- Garlic salt sesame seeds and dried parsley: sprinkle on top bring crunch and visual appeal
Instructions
- Thaw And Rise The Dough:
- Place frozen bread dough in a greased bowl and cover tightly with plastic wrap. Let it rest in a warm spot until completely thawed and doubled in size. This can take a few hours so plan ahead to get the perfect dough texture for rolling.
- Prepare The Vegetable Filling:
- Dice the bell pepper and onion evenly and thinly slice mushrooms. Heat a skillet over medium heat and melt one tablespoon of butter. Sauté the vegetables until soft and lightly browned which usually takes about six minutes. Then set aside to cool slightly before assembling to avoid sogginess.
- Preheat And Prep The Oven:
- Set your oven to 375 degrees Fahrenheit. Line a baking sheet with parchment paper or lightly spray it with cooking spray to prevent sticking and for easy cleanup.
- Roll Out The Dough:
- On a floured surface gently roll the risen dough into a 12 by 18 inch rectangle taking care to keep even thickness without tearing the dough.
- Make The Spread:
- Combine mayonnaise with garlic powder in a bowl and mix thoroughly. Spread this evenly across the rolled dough leaving a half inch border around the edges.
- Layer The Fillings:
- Arrange the roast beef slices over the mayonnaise base. Spread the sautéed vegetable mixture evenly on top of the beef. Finally place slices of provolone over the vegetables allowing some overlap for a gooey cheese layer.
- Roll The Stromboli:
- Starting at one long edge roll the dough tightly like a jelly roll. Tuck in any filling that tries to escape. Pinch the seams and ends firmly to seal in all the fillings.
- Prepare For Baking:
- Place the rolled stromboli seam side down on the baking sheet. Melt the remaining butter and brush it generously over the top. Sprinkle the crust evenly with garlic salt sesame seeds and dried parsley for crunch and pretty coloring.
- Bake Until Golden:
- Bake for 15 to 20 minutes until the crust is deep golden and the filling is heated through. The internal temperature should be at least 165 degrees Fahrenheit.
- Rest And Slice:
- Let the stromboli rest for about 5 minutes after baking to firm up. Use a serrated knife to slice and serve warm.

The melted provolone is my favorite part especially when it stretches from slice to slice. My kids say it is the best cheese pull they have ever seen which makes every bite extra fun. It’s those gooey moments that turn this stromboli into a beloved family classic.
Storage Tips
Wrap any leftovers tightly in foil or store in an airtight container in the refrigerator. They will keep well for up to three days. To reheat warm in a 350 degree oven for about ten minutes or until hot throughout to keep the crust crisp.
Ingredient Substitutions
Swap deli roast beef for leftover steak or cooked ground beef if you prefer. Cheddar or mozzarella make fine stand ins for provolone giving a milder cheese flavor while still melting nicely.
Serving Suggestions
Serve slices with marinara or garlic aioli on the side for dipping. Pair with a crisp green salad for lightness or roasted potatoes for a more filling meal.

Serve warm and enjoy the irresistible cheese pull. This stromboli is perfect for weeknights or casual gatherings.
