Cooking is not just about following recipes; it’s about crafting experiences in the kitchen. Let’s dive into creating a satisfying Low Carb Philly Cheesesteak Casserole that’ll become a family favorite.

Ingredients

To prepare this delightful dish, gather the following 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

Step-by-Step Guide to Making Low Carb Philly Cheesesteak Casserole

  1. Preheat the Oven
    Start by preheating your oven to 350°F (175°C) and prepare a 9×13 baking dish by spraying it with non-stick spray to create a no-fuss cleanup.

  2. Sauté Vegetables
    In a large skillet, heat the olive oil over medium heat. Once it’s shimmering, add the diced onions and bell peppers. Sauté for about 5-6 minutes until they soften and become fragrant.

  3. Add Garlic
    Toss in the minced garlic, stirring continually for another 30 seconds. This step will release the aromatic essence of garlic, enhancing the flavor profile of the casserole.

  4. Cook Ground Beef
    Next, add the ground beef to the mixture, using a spatula to break it up as it cooks. Season generously with salt and pepper. Continue cooking for 7-8 minutes until the beef is fully browned, ensuring there are no pink bits left. If there’s excess fat, drain it properly.

  5. Incorporate Worcestershire Sauce
    Add the Worcestershire sauce to the beef and vegetable mixture, stirring well to coat everything evenly. The richer flavors will provide depth and excitement to your casserole.

  6. Cream Cheese Magic
    Lower the heat to a gentle simmer and introduce the softened cream cheese into the skillet. Stir continuously until it’s melted and smoothly incorporated with the meat, creating a luscious creaminess.

  7. Transfer to Baking Dish
    Carefully transfer the beef and cheese mixture into your prepared baking dish, spreading it out to create an even layer.

  8. Add Cheese Layers
    Now, sprinkle the torn pieces of provolone cheese over the beef mixture, followed by an even layer of shredded mozzarella. This layering will ensure a gooey, cheesy topping that’s irresistible.

  9. Bake to Perfection
    Place the dish in the preheated oven and bake for 22-25 minutes. Keep an eye on it until the cheese is melted, bubbly, and adorned with a light golden hue.

  10. Rest and Serve
    Once out of the oven, allow the casserole to rest for about 5 minutes. This resting period lets the flavors meld together beautifully, giving you a delightful bite every time.
