Philly Cheesesteak Stromboli (Printer-Friendly)

Golden stromboli stuffed with roast beef, sautéed veggies, and melted provolone cheese for a comforting meal.

# What You’ll Need:

→ Dough

01 - 1 thawed frozen white bread loaf (approximately 450 g)

→ Spread

02 - 4 tablespoons mayonnaise
03 - 1 teaspoon garlic powder

→ Vegetable Filling

04 - 1 green bell pepper, diced (about 120 g)
05 - 1 medium yellow onion, diced (about 150 g)
06 - 120 g mushrooms, thinly sliced
07 - 2 tablespoons unsalted butter

→ Protein and Cheese

08 - 300 g thinly sliced deli roast beef
09 - 200 g provolone cheese slices

→ Topping

10 - 1 tablespoon unsalted butter, melted
11 - 1 teaspoon garlic salt
12 - 1 teaspoon sesame seeds
13 - 1 teaspoon dried parsley flakes

# Steps to Follow:

01 - Place the frozen white bread loaf in a greased bowl and cover with plastic wrap. Allow it to thaw and double in size in a warm environment, approximately 2 to 3 hours.
02 - Dice the green bell pepper and yellow onion evenly, and thinly slice the mushrooms. Heat 1 tablespoon of butter in a skillet over medium heat and sauté the vegetables until tender and lightly browned, about 6 minutes. Remove from heat and let cool slightly.
03 - Set the oven to 375 degrees Fahrenheit (190°C). Line a baking sheet with parchment paper or lightly grease it to ensure easy removal.
04 - On a floured surface, roll the risen dough into a rectangle approximately 12 by 18 inches (30 by 45 cm), ensuring even thickness without tearing.
05 - In a small bowl, combine mayonnaise and garlic powder. Mix thoroughly and spread evenly over the dough, leaving a 0.5-inch (1.25 cm) border around the edges.
06 - Evenly arrange the roast beef slices over the garlic mayo. Distribute the sautéed vegetables atop the meat, then layer provolone slices over the vegetables, overlapping as needed.
07 - Starting from a long edge, roll the dough like a jelly roll, keeping it tight and tucking in fillings to prevent spilling. Pinch the seams and ends firmly to seal.
08 - Place the stromboli, seam side down, on the prepared baking sheet. Brush the top with melted butter and sprinkle garlic salt, sesame seeds, and dried parsley evenly.
09 - Bake for 15 to 20 minutes or until the crust is golden brown and the internal temperature reaches 165 degrees Fahrenheit (74°C).
10 - Remove from oven and let rest for 5 minutes to firm up. Slice using a serrated knife and serve warm.

# Helpful Hints:

01 - Ensure the dough is fully thawed and risen prior to rolling for the best texture.
02 - Allow the sautéed vegetables to cool slightly before assembling to avoid soggy dough.
03 - Brush the top generously with melted butter to achieve a golden crust.
04 - Store leftovers wrapped tightly in foil or an airtight container in the refrigerator for up to 3 days.
05 - Reheat leftovers in a 350 degree Fahrenheit oven for 10 minutes to retain crust crispness.
