Directions

Step 1: Preheat Your Oven

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish to prevent sticking and ensure easy cleanup.

Step 2: Cook the Beef

If using ground beef, cook it in a large skillet over medium-high heat until fully browned. Be sure to drain any excess fat to keep the dish from becoming greasy. If using thinly sliced steak, heat olive oil in the skillet, add the steak slices, and cook until nicely browned. Once cooked, remove the steak from the skillet and set it aside.

Step 3: Sauté the Vegetables

In the same skillet, add a bit more olive oil if needed. Toss in the diced onions, bell peppers, and mushrooms (if using). Sauté the vegetables until they’re softened and aromatic, about 5-7 minutes. Stir occasionally to prevent burning. Add minced garlic during the last minute of cooking to infuse the dish with additional flavor.

Step 4: Combine Ingredients

Return the cooked beef or steak to the skillet with the sautéed vegetables. Stir in Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Mix well to ensure the flavors are evenly distributed. For a creamy texture, add softened cream cheese and beef broth to the skillet. Stir until the mixture is smooth and cohesive.

Step 5: Assemble the Casserole

Transfer the beef and vegetable mixture to the prepared baking dish, spreading it out evenly. Sprinkle shredded mozzarella cheese generously over the top. Arrange slices of provolone cheese on the surface to create a golden, bubbly layer of melted goodness.

Step 6: Bake

Place the assembled casserole in the preheated oven and bake for 25-30 minutes, or until the cheese is fully melted and the dish is heated through. The edges should be slightly golden, and the center should be set.

Step 7: Serve

Let the casserole cool slightly before serving. This allows the flavors to meld together and makes it easier to portion. Serve warm and enjoy every cheesy, savory bite!
