Ingredients
Scale
Bell Peppers
- 1 large green bell pepper
- 1 large yellow bell pepper
- 1 large red bell pepper
Vegetable Mix
- 2 tablespoons salted butter
- 1 small onion, thinly sliced
- 3 cloves garlic, minced
- 8 ounces cremini mushrooms, thinly sliced
Meat and Cheese
- 1 1/2 pounds deli-style roast beef, thinly sliced
- 6 slices provolone cheese
- 1 cup shredded mozzarella cheese
Instructions
- Prepare Peppers: Cut and slice the green, yellow, and red bell peppers, removing all seeds and ribs to ensure a tender texture in the casserole.
- Sauté Vegetables: Heat 2 tablespoons of salted butter in a skillet over medium heat. Add the thinly sliced onion and minced garlic, sautéing until fragrant and translucent. Then add the thinly sliced cremini mushrooms and bell peppers; cook all vegetables until they become tender and well combined.
- Add Beef: Mix the thinly sliced deli-style roast beef into the sautéed vegetables. Season the mixture lightly with salt and pepper to taste.
- Assemble and Top with Cheese: Transfer the beef and vegetable mixture into a casserole dish. Evenly layer the 6 slices of provolone cheese over the top, followed by sprinkling 1 cup of shredded mozzarella cheese.
- Bake and Broil: Preheat the oven to 350°F (175°C). Bake the casserole for 15 minutes to allow the flavors to meld and the cheese to melt. Then switch the oven to broil mode and broil the casserole until the cheese is browned, bubbly, and slightly crispy on top, about 2-3 minutes. Watch carefully to avoid burning.
Notes
- Make sure to slice the peppers uniformly for even cooking.
- You can use other types of cheese like American or cheddar for variation.
- Keep an eye on the casserole while broiling as cheese can burn quickly.
- This dish pairs well with a simple green salad or crusty bread.
