Ingredients
- Frozen white bread loaf: Fully thawed to ensure a crisp and well-risen crust
- Mayonnaise: Mixed with garlic powder adds moisture and subtle savory notes
- Butter: Brings richness and is used to sauté vegetables and brown the crust beautifully
- Green bell pepper: Adds a pop of color and slight sweetness pick firm shiny peppers
- Yellow onion: For savory depth select ones with dry crackly skin for best flavor
- Mushrooms: Contribute earthiness choose firm caps without dark spots for freshness
- Deli roast beef: Thinly sliced for a rich meaty layer over the dough
- Provolone cheese: Melts smoothly providing creamy richness that holds the stromboli together
- Garlic salt, sesame seeds and dried parsley: Finish the crust with crunch and visual appeal
Instructions
- Thaw and Rise the Dough:
- Place frozen white bread dough in a greased bowl and cover with plastic wrap. Let it rise in a warm space until fully thawed and doubled in size. This may take a few hours so plan ahead for the best texture and flavor.
- Prepare the Vegetable Filling:
- Dice the green bell pepper and yellow onion evenly and slice mushrooms thinly. Heat a skillet over medium heat and melt one tablespoon of butter. Sauté the vegetables until they soften and turn lightly browned about six minutes then remove from heat to cool slightly.
- Preheat and Prep the Oven:
- Set oven temperature to 375 degrees Fahrenheit. Line a baking sheet with parchment paper or spray with cooking spray to prevent the stromboli from sticking during baking.
- Roll Out the Dough:
- On a floured surface roll out the risen dough into a rectangle approximately twelve inches by eighteen inches. Aim to keep even thickness and avoid tearing the dough for ease of rolling and baking.
- Make the Spread:
- In a bowl combine mayonnaise with garlic powder mixing well. Spread this garlic mayo evenly across the surface of the rolled dough leaving a half inch border free around the edges.
- Layer the Fillings:
- Arrange the thinly sliced roast beef evenly over the mayonnaise. Next sprinkle the sautéed vegetables on top and then layer the provolone cheese slices overlapping if needed to cover fully.
- Roll the Stromboli:
- Starting from one long edge, roll the dough tightly like a jelly roll to enclose the fillings. Tuck any stray pieces inside and pinch the seams and ends securely to seal the stromboli completely.
- Prepare for Baking:
- Place the formed stromboli roll seam side down onto the prepared baking sheet. Melt the remaining tablespoon of butter and brush it generously over the top. Sprinkle garlic salt, sesame seeds, and dried parsley evenly over the surface for flavor and appearance.
- Bake Until Golden:
- Bake in the oven for fifteen to twenty minutes until the crust is golden brown and the filling is heated through. The internal temperature should reach one hundred sixty-five degrees Fahrenheit to ensure food safety.
- Rest and Slice:
- Allow the stromboli to rest for five minutes after baking to let it firm up. Use a serrated knife to slice into portions and serve warm for the best texture and flavor experience.

The melted provolone cheese is my favorite especially when it stretches as you pull a slice. My kids say this is the best cheese pull they have ever seen and it always brings big smiles around our table.
Storage Tips
Wrap leftovers tightly in foil or place in an airtight container and store in the refrigerator for up to three days. Reheat in a 350-degree oven for about ten minutes to keep the crust crisp and the filling thoroughly warmed.
Ingredient Substitutions
Swap deli roast beef for leftover steak or even cooked ground beef for a different texture. If you prefer a different cheese, cheddar or mozzarella both melt well and offer milder flavors that can freshen up the dish.
Serving Suggestions
Serve slices with a side of marinara sauce or garlic aioli for dipping. Add a fresh green salad to balance richness or roasted potatoes for a more filling meal.

Serve warm with marinara or garlic aioli for dipping and enjoy the melty cheese and buttery crust.
