Step-by-Step Instructions: Creating Your Culinary Masterpiece

Prepping the Bread

1. Preheat your oven to 350°F (175°C).
2. In a large bowl, toss the cubed Italian bread with melted butter and garlic powder.
3. Spread the bread cubes in a single layer on a baking sheet and bake for 10-12 minutes, or until lightly toasted. This will prevent the casserole from becoming soggy.

Cooking the Steak and Veggies

1. Heat olive oil in a large skillet over medium-high heat.
2. Add the sliced steak and cook until browned and cooked through. Be careful not to overcrowd the pan, or the steak will steam instead of brown. You may need to cook it in batches.
3. Remove the steak from the skillet and set aside.
4. Add the sliced onion and bell peppers to the skillet and cook until softened, about 8-10 minutes.
5. Add the minced garlic and cook for another minute until fragrant.
6. Return the steak to the skillet and mix with the vegetables. Season with salt and pepper to taste.

Making the Cheese Sauce

1. In a large saucepan, melt the butter over medium heat.
2. Whisk in the flour and cook for 1-2 minutes, stirring constantly, to create a roux.
3. Gradually whisk in the milk until smooth.
4. Bring to a simmer, stirring constantly, until the sauce thickens slightly.
5. Reduce heat to low and stir in the softened cream cheese until melted and smooth.
6. Stir in the provolone and mozzarella cheese until melted and the sauce is creamy.
7. Season with salt and pepper to taste.

Assembling the Casserole

1. Grease a 9×13 inch baking dish.
2. Spread the toasted bread cubes evenly in the bottom of the dish.
3. Pour the steak and vegetable mixture over the bread cubes.
4. Pour the cheese sauce over the steak and vegetables, making sure everything is evenly covered.

Baking Time!

1. Bake in the preheated oven for 20-25 minutes, or until the casserole is bubbly and the cheese is golden brown.
2. Let the casserole rest for 5-10 minutes before serving. This allows the cheese sauce to set slightly.

Tips and Tricks for Philly Cheesesteak Casserole Perfection

Let’s face it, even the easiest recipes can have a few potential pitfalls. But don’t worry, I’m here to help you avoid them!

• Don’t Overcrowd the Pan: When cooking the steak, make sure to cook it in batches. Overcrowding the pan will cause the steak to steam instead of brown, which will affect the flavor and texture.
• Toast the Bread: Toasting the bread cubes before assembling the casserole is crucial to prevent them from becoming soggy. Trust me, you don’t want a soggy casserole!
• Use Good Quality Cheese: The cheese sauce is the star of this dish, so don’t skimp on the quality of the cheese. Use good quality provolone and mozzarella cheese for the best flavor and melt.
• Adjust Seasoning to Taste: Don’t be afraid to adjust the seasoning of the steak, vegetables, and cheese sauce to your liking. Taste as you go and add more salt, pepper, or garlic powder as needed.

Variations and Substitutions: Make It Your Own!

One of the best things about casseroles is how easily you can customize them to your liking. Here are a few ideas for variations and substitutions:

• Cheese Options: While provolone and mozzarella are classic choices, feel free to experiment with other cheeses like cheddar, pepper jack, or even a bit of Swiss.
• Vegetable Additions: Add mushrooms, jalapenos, or banana peppers for an extra kick.
• Meat Alternatives: Ground beef or even shredded chicken can be used in place of the steak, though it won’t be a true Philly Cheesesteak Casserole.
• Low Carb Version: Swap out the Italian bread for cauliflower rice to keep the carbs down. You might also like Keto Cheesesteak Roll Perfection!
