🧀 What Is Philly Cheesesteak Casserole?

Philly Cheesesteak Casserole captures the essence of the famous sandwich from Philadelphia but simplifies it for home cooks. Instead of individual sandwiches, the ingredients are layered or mixed together in a casserole dish—topped with cheese and baked until bubbly. It’s an ideal weeknight dinner, blending flavors of steak, onions, peppers, and cheese, with an optional pasta or bread base for extra heartiness.

🥩 Ingredients You’ll Need

Here’s everything to make this irresistible dish:

• 1 pound ground beef (or thinly sliced ribeye for a more authentic cheesesteak flavor)
• 1 tablespoon olive oil
• 1 medium onion, diced
• 1 green bell pepper, diced
• 1 red bell pepper, diced
• 2 cloves garlic, minced
• 1 teaspoon Worcestershire sauce
• 1 teaspoon salt
• ½ teaspoon black pepper
• 1 teaspoon Italian seasoning (optional for added aroma)
• 4 ounces cream cheese, softened
• 1 cup shredded mozzarella cheese
• 1 cup provolone cheese, shredded or sliced
• 1 cup heavy cream or ½ cup milk + ½ cup cream cheese for a lighter option
• 8 ounces cooked pasta (like penne or egg noodles, optional if you want a fuller meal)
• Fresh parsley for garnish

🔪 Step-by-Step Instructions

Step 1: Prepare the Ingredients

Start by chopping your onion, bell peppers, and garlic. If using pasta, cook it al dente according to package instructions, drain, and set aside. Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch casserole dish.

Step 2: Cook the Beef and Vegetables

In a large skillet over medium heat, warm the olive oil. Add the ground beef and cook until browned, breaking it apart with a spatula. Drain any excess fat.
Next, add the chopped onions, green and red bell peppers, and garlic. Sauté for about 5–7 minutes until the vegetables are tender and fragrant.

Step 3: Season the Mixture

Stir in the Worcestershire sauce, salt, black pepper, and Italian seasoning. This step builds the classic savory cheesesteak flavor profile. Taste and adjust seasoning as desired.

Step 4: Make the Creamy Base

Reduce the heat to low and stir in the softened cream cheese until it melts smoothly into the beef mixture. Then, pour in the heavy cream, stirring gently to form a creamy sauce that coats the beef and veggies. This is what makes the casserole rich and comforting.

Step 5: Combine with Pasta (Optional)

If you’re including pasta, fold it into the skillet mixture until evenly coated with the cheesy sauce. This makes the dish more filling and gives it a lasagna-like texture. If you’re skipping the pasta, simply spread the beef mixture directly into the baking dish.
