Step-by-Step Instructions to Make This Philly Cheesesteak Casserole Recipe

1. Preheat the Oven

• Preheat your oven to 375°F (190°C) and grease a 9×13-inch casserole dish.

2. Sauté the Vegetables

• Heat olive oil in a large skillet over medium heat. Add diced bell peppers and sliced onions. Cook for 4–5 minutes, stirring occasionally, until softened. Add garlic and cook for another minute. Remove from the skillet and set aside.

3. Cook the Beef

• In the same skillet, cook the ground beef over medium heat until browned, breaking it apart with a spatula. Drain excess fat if necessary. Stir in Worcestershire sauce, Italian seasoning, salt, and pepper. Mix well and remove from heat.

4. Prepare the Egg Mixture

• In a medium bowl, whisk together the eggs and heavy cream until smooth. Season with a pinch of salt and pepper.

5. Assemble the Casserole

• Spread the cooked beef evenly in the bottom of the greased casserole dish. Layer the sautéed vegetables on top of the beef. Pour the egg mixture over the beef and vegetables, ensuring it’s evenly distributed. Sprinkle mozzarella and provolone cheese over the top.

6. Bake

• Bake the casserole for 25–30 minutes, or until the eggs are set and the cheese is melted and bubbly.

7. Garnish and Serve

• Let the casserole rest for 5 minutes before serving. Garnish with chopped parsley for a fresh, vibrant finish.

Common Mistakes to Avoid

• Skipping the Drain Step: Always drain excess fat from the beef to avoid a greasy casserole.
• Overcooking the Vegetables: Sauté the peppers and onions until just softened to maintain some texture.
• Uneven Egg Mixture: Whisk the eggs and cream thoroughly to ensure a consistent custard layer.
• Burning the Cheese: Keep an eye on the casserole during the last few minutes to avoid over-browning the cheese.

Serving and Presentation Tips

• Pair with Sides: Serve with a crisp green salad, garlic bread, or roasted vegetables for a complete meal.
• Family-Style: Serve directly from the baking dish for a cozy, homestyle presentation.
• Individual Portions: Cut into squares and plate with a sprinkle of parsley for a polished look.

Expert Tips

• Make It Ahead: Assemble the casserole up to 24 hours in advance and refrigerate. Add 5–10 minutes to the baking time if cooking from cold.
• Reheat Leftovers: Warm leftovers in the oven at 350°F (175°C) for 10–15 minutes or in the microwave until heated through.
• Double the Recipe: For larger gatherings, double the ingredients and bake in two dishes.
