Key Ingredients Overview
Protein Base
- Ground Beef (1½ pounds): The foundation of our casserole, providing savory depth and satisfying protein.
Fresh Produce
- Green Bell Peppers (2, sliced thin): Traditional Philly cheesesteak component that adds freshness and texture.
- Yellow Onion (½, sliced thin): Provides aromatic sweetness when properly caramelized.
- Garlic (2 teaspoons, minced): Adds depth of flavor and aromatic complexity.
Seasonings & Binding Elements
- Seasoned Salt (1 teaspoon): A balanced blend that seasons the entire dish efficiently.
- Eggs (4 large): Creates structure and richness in the casserole base.
- Worcestershire Sauce (2 teaspoons): Adds umami depth that enhances the beef flavor.
- Heavy Whipping Cream (¼ cup): Creates a silky, rich texture similar to HelloFresh cream sauce base recipes.
Topping
- Provolone Cheese (8 slices): Melts perfectly to create that authentic cheesesteak experience.
Detailed Step-by-Step Instructions
1. Preheat Oven
Preheat your oven to 375°F (190°C). This moderate temperature allows the casserole to cook evenly without burning the cheese topping.
Chef's Pro Tip: Allow your oven to preheat for at least 15-20 minutes to ensure it reaches the proper temperature throughout, similar to the approach used in HelloFresh recipes for consistent results.
2. Cook Ground Beef
Heat a large skillet over medium heat until hot but not smoking. Add the ground beef, breaking it into small pieces with a wooden spoon or heat-resistant spatula.
Cook the beef until thoroughly browned and no pink remains, about 7-9 minutes. Stir occasionally to ensure even cooking.
Chef's Pro Tip: Don't stir the beef constantly. Allowing it to develop a crust against the pan creates deeper flavor through the Maillard reaction, a technique often highlighted in professional cooking.
Once fully cooked, carefully drain excess fat from the skillet. You can use a colander, but for best results, tilt the skillet and remove fat with a spoon, leaving about 1 tablespoon for flavor.
3. Sauté Vegetables
Return the skillet with the drained beef to medium heat. Add the thinly sliced bell peppers, onion, and minced garlic to the skillet.
Cook the vegetables with the beef until they become tender but still maintain some texture, about 5-7 minutes. The onions should become translucent but not brown.
Season the mixture with 1 teaspoon of seasoned salt, stirring to distribute evenly throughout.
Chef's Pro Tip: Slice your peppers and onions to uniform thickness (about ⅛ inch) to ensure they cook evenly and create the perfect texture in your finished casserole.
4. Prepare Egg Mixture
In a medium mixing bowl, whisk together 4 large eggs until well beaten. Add 2 teaspoons of Worcestershire sauce and ¼ cup of heavy whipping cream.
Whisk these ingredients together until fully incorporated and smooth. This mixture creates a rich, creamy binding agent for your casserole.
Chef's Pro Tip: Whisk your egg mixture thoroughly to incorporate air, which helps create a lighter texture in the finished casserole.
5. Combine Ingredients
Remove the skillet from heat and allow the beef and vegetable mixture to cool slightly for about 2-3 minutes.
Gradually add the beef and vegetable mixture to the egg mixture, stirring gently to combine. This technique prevents the hot beef from cooking the eggs prematurely.
Troubleshooting Tip: If your egg mixture begins to curdle when adding hot ingredients, whisk vigorously and add a tablespoon of cold heavy cream to stabilize.
6. Assemble Casserole
Lightly grease a 9×13 inch baking dish with cooking spray or butter to prevent sticking.
Spread the combined beef, vegetable, and egg mixture evenly across the bottom of the prepared baking dish.
Arrange 8 slices of provolone cheese over the top, slightly overlapping to ensure complete coverage when melted.
Chef's Pro Tip: For a more professional presentation, arrange the cheese so the edges slightly overlap but the center of each slice is visible. This creates an attractive pattern when melted.
7. Bake the Casserole
Place the assembled casserole on the middle rack of your preheated oven.
Bake for 25-30 minutes, or until the center is set and the cheese is melted, bubbly, and beginning to brown on top.
Troubleshooting Tip: If your cheese is browning too quickly but the casserole isn't fully set, tent loosely with aluminum foil to prevent burning.
8. Cool and Serve
Remove the casserole from the oven and let it rest for 5-10 minutes before serving. This resting period allows the casserole to set and makes for neater portions when serving.
Chef's Pro Tip: Cut the casserole with a sharp knife that's been run under hot water and wiped clean between cuts for the cleanest presentation.
