Step-by-step instructions
- Preheat and prepare: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with butter or nonstick spray.
- Sauté vegetables: In a large skillet over medium-high heat, warm 1 tablespoon olive oil. Add the sliced onions and peppers and cook until soft and slightly caramelized, about 8–10 minutes. Add garlic for the last minute and remove vegetables to a bowl.
- Brown the beef: Add the remaining tablespoon of olive oil to the skillet. Add the beef in a single layer and let it brown without stirring for 2 minutes, then break up and continue cooking until no pink remains. Season with smoked paprika, onion powder, salt, and pepper. Drain any excess liquid.
- Make the cheese sauce: In a small saucepan, melt butter over medium heat. Whisk in flour and cook 1 minute. Gradually whisk in milk and cook until thickened, about 3–5 minutes. Remove from heat and stir in 1¼ cups provolone and the cheddar until melted and smooth.
- Layer the casserole: Spread half of the biscuit pieces or bread cubes in the prepared dish. Top with half the beef, half the sautéed vegetables, and half the cheese sauce. Repeat the layers, finishing with the remaining provolone on top.
- Bake: Cover loosely with foil and bake 20 minutes. Remove foil and bake an additional 10–15 minutes until the top is golden and the casserole is bubbling.
- Rest and serve: Let rest 5–10 minutes so it slices neatly. Garnish with chopped parsley or a drizzle of hot sauce if desired.
If you enjoy casseroles with layered textures, the assembly method is similar to the Angel Chicken and Rice Casserole method, which is helpful practice for beginners.
Tips for success
- Use thinly sliced beef so it cooks quickly and stays tender. If pieces are too thick, slice them against the grain.
- Don’t skip the resting time after baking; it helps the casserole set so servings hold their shape.
- For a smoother sauce, warm the milk slightly before adding it to the roux (but don’t boil).
- If your peppers or onions brown too quickly, lower the heat and cook slowly to build sweetness.
- For visual and flavor balance, shred your cheese rather than using pre-sliced singles—freshly shredded melts more evenly.

Possible variations
- Gluten-free: Use a gluten-free biscuit dough or cubed gluten-free bread, and substitute a gluten-free flour blend for the roux to make this Philly Cheesesteak Casserole gluten-free-friendly.
- Vegetarian: Replace the beef with seasoned, sautéed mushrooms and firm tofu or a store-bought meat substitute; keep the savory onions and peppers.
- Streusel topping: For a fun sweet-savory twist, mix ½ cup panko (or gluten-free panko), 2 tablespoons melted butter, and ¼ cup grated Parmesan, then sprinkle on top in the last 10 minutes of baking for a crisp topping.
- Mix-and-match cheeses: Swap provolone for mozzarella and add a little Gruyère for a nuttier profile; inspiration for bold swaps can come from casseroles like the Cattle Drive Casserole.
Storage recommendations
- Refrigerator: Cool the casserole completely, cover tightly, and store up to 4 days.
- Freezer: Portion into airtight containers and freeze up to 3 months. Thaw overnight in the fridge before reheating.
- Reheating: Warm single portions in the microwave for 1–2 minutes or reheat a whole pan covered with foil at 350°F until heated through, about 20–30 minutes.
