Easy Philly Cheesesteak Casserole for a Hearty Dinner Tips, FAQ & printable recipe

Tips for success

For a slightly spicy kick, incorporate diced jalapeños along with the bell peppers. This adds a nice contrast to the richness of the cheese and beef. Ensure the jalapeños are seeded if a milder heat is preferred, and remember to wash your hands thoroughly after handling them to avoid irritation. These small adjustments can significantly elevate the flavor profile of the dish.

If you prefer a deeper flavor, consider adding a dash of Worcestershire sauce or a sprinkle of garlic powder to the beef while it is browning. These simple additions enhance the savory notes of the dish without requiring complex preparation.

Always taste the beef mixture before adding the cheese to ensure it is seasoned to your preference, as the cheese provides a salty element that balances the dish.

Variations

• Mushroom Philly Casserole: Add 8 ounces of sliced cremini mushrooms to the skillet when sautéing the peppers. The mushrooms provide an earthy depth that complements the beef perfectly.
• Spicy Philly Casserole: Incorporate diced jalapeños or a tablespoon of hot sauce into the beef mixture. This variation offers a subtle heat that cuts through the richness of the melted cheese.

Storage and make-ahead

Fridge

Store in an airtight container for up to 3 days.

Freezer

Store in a freezer-safe container for up to 2 months. Thaw in the refrigerator overnight before reheating.

Reheat

Reheat in a 350°F oven until hot or in the microwave in 1-minute intervals until steaming.

Allow any leftover casserole to cool to room temperature within two hours of baking before storing. Transfer the leftovers to an airtight container to maintain moisture and prevent the absorption of other odors in the refrigerator.

Properly stored, the casserole will remain fresh and safe to consume for up to three days. Always ensure the container is tightly sealed to keep the cheese from drying out during storage.

The beef and vegetable mixture can be prepared up to one day in advance and stored in the refrigerator. When ready to serve, assemble the casserole in the baking dish, top with the cheese, and bake according to the instructions. If baking directly from the refrigerator, you may need to add an extra 5 to 10 minutes to the total baking time to ensure the center is thoroughly heated.

Serving ideas

Serve the casserole hot directly from the baking dish for the best experience. The cheese pull is most impressive when the dish is fresh out of the oven.

Use a sturdy metal spatula to portion the casserole onto plates, ensuring each serving includes a good balance of the beef, vegetables, and the melted cheese topping. This dish pairs well with a side salad or crusty bread to soak up any remaining juices.

For a more casual serving style, consider placing the casserole dish in the center of the table and allowing diners to serve themselves. This encourages a communal dining experience.

If there are leftovers, they can be portioned into individual containers for easy future meals. Ensure that each portion is reheated until steaming hot to maintain the quality and safety of the food for every subsequent serving.

Ingredients

• 2 lb ground beef
• 2 bell peppers, sliced
• 2 cups shredded mozzarella cheese

Instructions

1. Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a spatula, until browned and cooked through. Ensure the internal temperature reaches 160°F (71°C). Drain any excess grease from the skillet.
2. Add the sliced bell peppers to the skillet with the cooked beef. Continue to sauté the mixture over medium heat until the vegetables are softened, about 5 to 7 minutes.
3. Transfer the beef and vegetable mixture into a 9x13 inch baking dish. Spread the mixture evenly across the bottom of the dish to create an even layer before adding the cheese topping.
4. Sprinkle the shredded mozzarella cheese generously over the top of the beef and vegetable layer. Ensure the entire surface is covered so the cheese melts into a cohesive layer.
5. Place the baking dish into a preheated oven at 375°F (190°C). Bake for approximately 15 to 20 minutes, or until the cheese is melted, bubbly, and slightly golden on top.
6. Remove the casserole from the oven and let it rest for 5 minutes before serving. This allows the juices to settle and the cheese to set slightly, making it easier to scoop.
