Ingredients
- 1 frozen white bread loaf, thawed
- 1/2 cup mayonnaise
- 1 teaspoon garlic powder
- 1 green bell pepper, diced
- 1 medium yellow onion, diced
- 1 cup mushrooms, thinly sliced
- 8 ounces deli roast beef, thinly sliced
- 8 ounces provolone cheese, sliced
- 2 tablespoons unsalted butter, divided
- 1 teaspoon garlic salt
- 1 teaspoon sesame seeds
- 1 teaspoon dried parsley
Instructions
- Place thawed bread dough in a greased bowl, cover with plastic wrap, and let rise for 2–3 hours until doubled in size.
- Dice bell pepper and onion, slice mushrooms, and sauté in 1 tablespoon butter over medium heat for about 6 minutes until tender and browned.
- Preheat oven to 375°F (190°C) and prepare a baking sheet with parchment paper or nonstick spray.
- Roll risen dough into a 12×18 inch rectangle on a floured surface.
- Mix mayonnaise and garlic powder, then spread evenly over dough, leaving a 1/2-inch border.
- Layer roast beef, sautéed vegetables, and provolone cheese over the dough.
- Roll dough tightly like a jelly roll and pinch seams and ends to seal.
- Place seam-side down on baking sheet. Brush with melted butter and sprinkle with garlic salt, sesame seeds, and dried parsley.
- Bake for 15–20 minutes until golden brown and internal temperature reaches 165°F (74°C).
- Let rest for 5 minutes before slicing and serving warm.
Notes
- Can be prepared ahead and refrigerated before baking.
- Use marinara sauce for dipping or serve with a fresh side salad.
- To freeze unbaked stromboli, wrap tightly and bake from frozen, adding extra time.
- Swap roast beef with turkey, chicken, or roasted veggies for variation.
- Reheat leftovers in oven for best texture.
