Ingredients for Philly Cheesesteak Casserole with Bell Peppers

Ground beef is the heart of this dish, providing a savory, meaty base that holds the casserole together. Onion and garlic add depth and aromatic richness, while green and red bell peppers contribute sweetness and vibrant color. The savory punch from Worcestershire sauce and the earthy warmth of dried oregano balance the flavors beautifully. Provolone cheese melts smoothly, offering a creamy texture, while mozzarella cheese brings that irresistible, stretchy cheese pull. A splash of beef broth keeps everything moist, and French bread cubes absorb the savory juices, becoming soft yet slightly crispy on top.

Tips & Tricks

  • Use day-old French bread; it holds up better against the moisture.
  • For a spicier kick, add a pinch of red pepper flakes.
  • Letting the casserole rest for a few minutes after baking helps the layers set.

Serving Suggestions

This casserole is a meal in itself, but it pairs wonderfully with a crisp green salad or roasted vegetables for some extra greenery. A side of tangy pickles can also complement the rich flavors of the cheesesteak.

Philly Cheesesteak Casserole with Bell Peppers Recipe Walkthrough

First, preheat your oven to 375°F (190°C) so it's ready to go when you are. Heat up some olive oil in a large skillet over medium heat, then toss in the diced onion and minced garlic. Stir them around until the onion turns translucent and your kitchen smells fantastic.

Next, add the ground beef to the skillet. Break it up with a spatula, and cook until it's nicely browned. Stir in the Worcestershire sauce, salt, black pepper, and oregano to season the meat perfectly.

Add the sliced green and red bell peppers to the skillet. Cook them for about 5 minutes, just until they start to soften. Pour in the beef broth to bring everything together. Give it a good mix to combine all the flavors.

Now, grab a greased casserole dish and spread the cubed French bread evenly across the bottom. Pour the beef and pepper mixture over the bread, ensuring it's evenly distributed. Top this with slices of provolone cheese, followed by a generous handful of shredded mozzarella.

Bake your assembled casserole in the preheated oven for 20-25 minutes. You'll know it's ready when the cheese is melted and bubbly with a slight golden hue. Let it cool for a few minutes before serving — this will make it easier to cut and serve.
