Low Carb Philly Cheesesteak Casserole Ingredients

• The key to this flavorful dish lies in quality ingredients!

For the Casserole

Ground Beef – A generous 2 lbs ensures a protein-packed base; opt for an 80/20 fat ratio for the best flavor.
Onion – One large onion adds sweetness and depth; you may swap it for shallots if you prefer a milder flavor.
Bell Peppers – Use 2 large peppers in any color for a pop of color and crunch; mixing colors elevates the visual appeal.
Garlic – Two cloves of minced garlic deliver aromatic notes that enhance all the flavors; fresh garlic is highly recommended.
Cream Cheese – Eight ounces of softened cream cheese bring creaminess to the mix; ricotta can be a great substitute for a lighter option.
Worcestershire Sauce – Two tablespoons introduce a savory umami kick; for a gluten-free choice, soy sauce works too.
Salt and Pepper – Adjust seasonings to taste; a pinch of salt helps brighten the flavors of the casserole.

For the Cheesy Topping

Provolone Cheese – Eight ounces of sliced provolone create a melty finish typical of a cheesesteak; cheddar adds its own unique flavor if you’d like to switch it up.
Mozzarella Cheese – One and a half cups of shredded mozzarella provide that irresistible cheesy pull; feel free to use low-fat versions if preferred.

How to Make Low Carb Philly Cheesesteak Casserole

Preheat Oven: Begin by preheating your oven to 350°F (175°C). This ensures your casserole bakes evenly and develops a lovely golden on top!
Sauté Veggies: Heat 1 tablespoon of olive oil in a large skillet over medium heat. Sauté the diced onion and bell peppers until they’re soft and fragrant, about 5-6 minutes, then add in the minced garlic for an extra 30 seconds.
Cook Beef: Add 2 pounds of ground beef to the skillet, breaking it apart with a spatula. Season generously with salt and pepper, cooking until browned (approximately 7-8 minutes); drain any excess fat if necessary for a firmer texture.
Combine Ingredients: Stir in 2 tablespoons of Worcestershire sauce and lower the heat. Add in 8 oz of softened cream cheese, mixing until it’s melted and creamy—this will bind all the flavors together perfectly!
Transfer to Baking Dish: Spoon the beef mixture into a greased 9×13 baking dish, spreading it out evenly. Then, top with 8 oz of torn provolone and sprinkle 1.5 cups of shredded mozzarella over the top.
Bake: Place your casserole in the oven and bake for 22-25 minutes, or until the cheese is beautifully melted and bubbly. Let it rest for 5 minutes before diving in for a comforting slice!

Optional: Garnish with fresh herbs for an added touch of flavor and color.
