Ingredients
- 1 lb thinly sliced beef (about 450 g)
- 1 medium onion, thinly sliced
- 1 green bell pepper, thinly sliced
- 8 oz mushrooms, sliced (optional)
- 2 tablespoons olive oil or butter
- 2 cloves garlic, minced
- 1 teaspoon kosher salt
- 1/2 teaspoon black pepper
- 1 teaspoon smoked paprika
- 1 cup shredded provolone or mozzarella
- 1/2 cup shredded cheddar (optional)
- 2 cups frozen hash browns (thawed) or 3 cups cubed bread for a richer base
- 1 cup beef broth
- 1/2 cup sour cream or Greek yogurt
- 2 large eggs, lightly beaten
- 1 tablespoon Worcestershire sauce
Note: For a meaty, traditional base, use thinly sliced beef; if you prefer a quicker swap, try a ground beef variation like other cooks use in ground beef Philly cheesesteaks.
Step-by-step Instructions
- Preheat and prep: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish.
- Sauté vegetables: In a large skillet over medium heat, warm olive oil. Add onions and peppers, cooking 6–8 minutes until softened. Add mushrooms and cook another 3–4 minutes. Stir in garlic for 30 seconds.
- Brown the beef: Push veggies to the side and add the beef, seasoning with salt, pepper, and smoked paprika. Cook until no longer pink and slightly browned. Stir everything together and finish with Worcestershire sauce.
- Make the custard base: In a medium bowl, whisk beef broth, sour cream, and eggs until smooth.
- Assemble the casserole: Spread hash browns (or cubed bread) in the bottom of the prepared dish. Layer the beef and vegetable mixture evenly over the base. Sprinkle the shredded provolone and cheddar over the top. Pour the broth mixture slowly, letting it settle around the layers.
- Bake: Cover with foil and bake 25 minutes. Remove foil and bake another 10–15 minutes until bubbling and the top is lightly golden.
- Rest and serve: Let rest 10 minutes before slicing so it sets. Serve warm with crunchy pickles or a simple salad. For a different serving style, you might enjoy a lighter version like the Philly Cheesesteak Bowl.
Tips for Success
- Use thinly sliced beef and don’t overcrowd the pan; browning in batches gives better flavor.
- If your vegetables release a lot of water, drain excess liquid before assembling so the casserole isn’t soggy.
- Let the casserole rest after baking—this helps slices hold their shape.
- For extra melty cheese, cover with foil for most of the bake time and uncover for the last minutes to brown.
- If you want to speed up prep, try one-pan shortcuts as used in other quick casseroles like the 15-minute Texas King Ranch Chicken Casserole for timing ideas.
Possible Variations
- Gluten-free: Swap the bread or hash browns base for a certified gluten-free hash brown or a layer of cooked quinoa or cauliflower rice for a lighter crust.
- Streusel topping: For a playful twist, try a savory streusel—combine panko (or gluten-free crumbs), melted butter, grated Parmesan, and a little parsley; sprinkle on top for a crunchy finish.
- Vegetarian: Replace beef with seasoned mushrooms and lentils or a plant-based ground alternative and boost umami with soy sauce or tamari.
- Lighter option: Use low-fat dairy or Greek yogurt and reduce cheese slightly for fewer calories while keeping rich flavor. For more casserole inspiration that blends cozy comfort and kitchen-friendly techniques, see the Angel Chicken and Rice Casserole for ideas on comforting layers and mix-ins.
Storage Recommendations
- Refrigerator: Cool completely, cover tightly, and store up to 3–4 days. Reheat individual portions in the microwave or the whole dish covered at 350°F (175°C) until warmed through.
- Freezer: Freeze individual slices wrapped in foil and stored in an airtight container for up to 3 months. Thaw overnight in the fridge before reheating. To avoid sogginess, reheat covered until hot, then uncover to crisp the top for 5–10 minutes.
