Introduction

This Low Carb Philly Cheesesteak Casserole is a hearty, flavorful dish that brings the classic sandwich flavors to a comforting baked meal. Packed with ground beef, roasted peppers, onions, and gooey cheese, it’s perfect for an easy weeknight dinner that the whole family will enjoy.

A white round ceramic dish holds a casserole with a golden-brown top layer that looks crispy and baked. The casserole slice on a spoon reveals three layers: the top layer is melted cheese, light golden with small green pepper pieces scattered on it; the middle layer is creamy white, smooth in texture; the bottom layer is a mix of cooked ground meat, dark brown with bits of red and green bell peppers. The spoon is lifting the casserole from the dish, showing all layers clearly. The setting is on a white marbled surface. Photo taken with an iphone --ar 4:5 --v 7

Ingredients

2 lbs ground beef (80/20 fat ratio preferred)
1 large onion, diced
2 large bell peppers (green, red, or mixed), diced
2 cloves garlic, minced
8 oz cream cheese, softened to room temperature
2 tbsp Worcestershire sauce
Salt and pepper to taste
8 oz provolone cheese, sliced
1.5 cups mozzarella cheese, shredded
1 tbsp olive oil

Instructions

Step 1: Preheat your oven to 350°F (175°C) and spray a 9×13 baking dish with non-stick spray. Heat olive oil in a large skillet over medium heat.
Step 2: Add diced onions and bell peppers to the hot oil. Cook for 5-6 minutes until they start to soften and become fragrant. Add minced garlic and cook for another 30 seconds, stirring constantly to prevent burning.
Step 3: Add ground beef to the skillet, breaking it up with your spatula as it cooks. Season generously with salt and pepper. Cook for 7-8 minutes until completely browned with no pink remaining. Drain excess fat if needed.
Step 4: Stir in Worcestershire sauce and let it coat the meat mixture for enhanced flavor. Reduce heat to low and add the softened cream cheese. Stir until completely melted and creamy.
Step 5: Transfer the mixture to your prepared baking dish and spread evenly. Layer torn provolone pieces over the beef, then top with shredded mozzarella.
Step 6: Bake for 22-25 minutes until cheese is melted, bubbly, and lightly golden on top. Let rest for 5 minutes before serving to allow flavors to meld together.

Tips & Variations

For extra flavor, add sliced mushrooms or jalapeños with the peppers and onions.
Try swapping mozzarella for cheddar or Monterey Jack for a different cheese profile.
Use turkey or chicken ground meat as a leaner alternative.
If you prefer, add a splash of hot sauce for a little kick.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, warm in the oven at 350°F (175°C) for 10-15 minutes or until heated through. You can also microwave individual servings until hot, but baking helps keep the cheese melted and bubbly.

How to Serve

On top, there is a golden-brown melted cheese layer with crispy spots and fresh green parsley sprinkled across. A spoon lifts a portion, revealing gooey, stretchy cheese pulling away from the main dish. The dish rests on a white marbled surface, and the lighting highlights the rich colors and textures.

FAQs

Can I make this casserole dairy-free?

You can substitute the cream cheese, provolone, and mozzarella with dairy-free alternatives available in most grocery stores, but the texture and flavor will be a bit different.
