  • Total Time: 45 minutes
  • Yield: 6 servings

Ingredients

Vegetables

  • 1 large green bell pepper
  • 1 large yellow bell pepper
  • 1 large red bell pepper
  • 1 small onion, thinly sliced (about 1/2 cup)
  • 3 cloves garlic, minced
  • 8 ounces cremini mushrooms, thinly sliced

Main Ingredients

  • 2 tablespoons salted butter
  • 1 1/2 pounds deli-style roast beef, thinly sliced
  • 6 slices provolone cheese (about 6 ounces)
  • 1 cup shredded mozzarella cheese

Instructions

  1. Prepare Peppers: Cut the tops off the green, yellow, and red bell peppers, remove ribs and seeds, then thinly slice the peppers. Set aside for cooking.
  2. Sauté Onions and Garlic: In a large deep-sided ovenproof skillet or Dutch oven, heat 2 tablespoons of salted butter over medium-low heat. Add the thinly sliced onion and minced garlic and cook, stirring occasionally, until the onion becomes translucent and the garlic is fragrant, about 7 minutes.
  3. Cook Mushrooms and Peppers: Add the thinly sliced cremini mushrooms and prepared bell peppers to the skillet. Continue cooking, stirring occasionally, until the mushrooms release their liquid and the peppers are crisp-tender, approximately 10 minutes.
  4. Preheat Oven: While the vegetables cook, preheat your oven to 350°F (175°C) to prepare for baking the casserole.
  5. Add Roast Beef and Cheese: Stir in the thinly sliced deli-style roast beef with the cooked vegetables in the skillet. Taste the mixture and add salt and pepper if desired. Layer the 6 slices of provolone cheese evenly over the top, followed by sprinkling 1 cup of shredded mozzarella cheese for a rich cheesy topping.
  6. Bake and Broil: Place the skillet in the preheated oven and bake for 15 minutes. After baking, finish the dish under the broiler for 2 to 3 minutes until the cheese is browned, bubbly, and slightly crisped on top. Remove carefully and serve warm.

Notes

  • Use an ovenproof skillet or Dutch oven to seamlessly transition from stovetop to oven.
  • Thinly slicing the bell peppers and roast beef ensures even cooking and better flavor absorption.
  • Adjust seasoning with salt and pepper to taste since roast beef can sometimes be salty.
  • For a spicier kick, add sliced jalapeños or drizzle with hot sauce before serving.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
