Ingredients

This recipe serves six hearty portions and uses simple, wholesome ingredients that are easy to find at your local grocery store.

• 2 lbs ground beef (80/20 fat ratio preferred for juiciness)
• 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

Equipment

• 9×13 baking dish
• Large skillet
• Oven
• Spatula or wooden spoon

Ingredient Notes

• Ground beef: Using a higher fat content like 80/20 ensures the casserole is juicy and flavorful. Leaner meat can dry out during baking.
• Bell peppers and onions: These vegetables add sweetness, texture, and a touch of freshness to balance the rich, cheesy flavors.
• Cream cheese: Helps bind the meat and vegetables together while adding creamy richness. Ensure it is softened to prevent lumps.
• Cheeses: Provolone gives the classic Philly flavor, while mozzarella adds stretchiness and gooey texture. Cheddar or other melty cheeses can be substituted based on preference.
• Olive oil: Used for sautéing vegetables. Can be swapped for avocado oil or butter if desired.
• Worcestershire sauce: Adds umami depth, balancing the richness of the cheese and beef.

Preparation Method

Follow these steps carefully to ensure a perfectly balanced, cheesy, and satisfying casserole.

Step 1: Preheat and Prepare Baking Dish

1. Preheat your oven to 350°F (175°C).
2. Spray a 9×13-inch baking dish with non-stick spray. This will prevent the cheese from sticking and make cleanup easier.

Step 2: Sauté Vegetables

1. Heat 1 tablespoon olive oil in a large skillet over medium heat.
2. Add the diced onions and bell peppers. Sauté for 5-6 minutes until they begin to soften and release their natural sweetness.
3. Add minced garlic and cook for another 30 seconds, stirring constantly to prevent burning.

Tip: Avoid overcooking the garlic—it can become bitter quickly. The goal is fragrant and lightly softened vegetables.

Step 3: Cook the Ground Beef

1. Add the 2 lbs ground beef to the skillet with the vegetables.
2. Break up the meat with a spatula and cook for 7-8 minutes, seasoning generously with salt and pepper, until fully browned with no pink remaining.
3. Drain excess fat if necessary to prevent the casserole from becoming greasy.

Step 4: Add Flavor and Creaminess

1. Stir in 2 tablespoons Worcestershire sauce, coating the meat mixture evenly. This adds a savory, umami depth.
2. Reduce the heat to low, then add the 8 oz softened cream cheese.
3. Stir continuously until the cream cheese is fully melted and incorporated, forming a rich, creamy mixture that binds the meat and vegetables together.

Step 5: Assemble the Casserole

1. Transfer the beef and vegetable mixture to your prepared 9×13 baking dish. Spread it evenly with a spatula.
2. Layer torn provolone cheese pieces over the top of the beef mixture.
3. Sprinkle 1.5 cups shredded mozzarella evenly over the provolone.

Tip: For extra cheesiness, you can mix in some shredded provolone or add a few tablespoons of Parmesan for a sharp flavor boost.

Step 6: Bake

1. Bake the casserole at 350°F (175°C) for 22–25 minutes, or until the cheese is melted, bubbly, and lightly golden on top.
2. Remove from the oven and let it rest for 5 minutes before serving. This allows the flavors to meld and makes serving easier.

Serving Suggestions

• Serve with a simple green salad to add freshness and balance the richness.
• Pair with roasted or sautéed low-carb vegetables like zucchini, asparagus, or broccoli for a complete meal.
• For meal prep, divide into individual portions and store in airtight containers in the fridge for up to 4 days.

Tips for the Perfect Low Carb Philly Cheesesteak Casserole

1. Choose the Right Beef: A fattier cut like 80/20 ensures juiciness. Leaner beef may require added moisture such as a splash of beef broth.
2. Don’t Overcook Vegetables: Slightly firm vegetables retain their texture and provide contrast to the creamy cheese and tender beef.
3. Softened Cream Cheese: Warm cream cheese mixes more easily and prevents clumps in the casserole.
4. Cheese Layers: Use thin slices of provolone to allow for even melting. Shredded mozzarella ensures gooey, melty coverage.
5. Drain Excess Fat: Removing extra grease prevents the casserole from becoming soggy.

Variations

• Spicy Cheesesteak Casserole: Add diced jalapeños or a dash of red pepper flakes to the vegetable mixture.
• Cheddar or Swiss Cheese: Swap provolone with your favorite cheese to change flavor profiles.
• Low-Sodium Option: Use reduced-sodium Worcestershire sauce and cheeses to control salt intake.
• Vegetable Boost: Add mushrooms, spinach, or zucchini to increase fiber and nutrients.
