1 tbsp olive oil

How to Make Low Carb Philly Cheesesteak Casserole

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Spray a 9×13 baking dish with non-stick spray to ensure your casserole won’t stick.

Step 2: Sauté the Vegetables

Heat the olive oil in a large skillet over medium heat. Add the diced onions and bell peppers:

2. Add minced garlic and cook for another 30 seconds until fragrant.

Step 3: Brown the Ground Beef

Add the ground beef to the skillet with the vegetables:
1. Season with salt and pepper to taste.
2. Cook while breaking up the meat with a spatula until completely browned, about 7-8 minutes.

Step 4: Combine Ingredients

Stir in Worcestershire sauce:
1. Allow it to coat the meat mixture and enhance the flavors.

Step 5: Mix in Cream Cheese

Reduce heat to low:
1. Add softened cream cheese to the skillet.
2. Stir until it melts completely and coats the meat and vegetable mixture evenly.

Step 6: Transfer to Baking Dish

Once fully combined:
1. Transfer the mixture to your prepared baking dish, spreading it evenly.

Step 7: Add Cheese Toppings

Layer sliced provolone cheese over the beef mixture:
1. Sprinkle shredded mozzarella cheese evenly on top.

Step 8: Bake

Place in preheated oven:
1. Bake for 20-25 minutes until cheese is melted, bubbly, and slightly golden on top.

Step 9: Serve

Allow casserole to rest for 5 minutes before serving:

Common Mistakes to Avoid

When preparing your Low Carb Philly Cheesesteak Casserole, it’s easy to overlook a few details. Here are common mistakes to avoid for the best results.

Not Prepping Ingredients First: Failing to chop onions and peppers before cooking can delay your meal. Always prepare your veggies in advance for a smoother cooking process.
Overcooking the Vegetables: Cooking vegetables too long can make them mushy. Sauté them just until they start to soften for a perfect texture in your casserole.
Using Cold Cream Cheese: Adding cold cream cheese can create lumps in your dish. Ensure it’s at room temperature before mixing it into the beef and veggie mixture.
Skipping the Resting Time: Cutting into the casserole immediately might cause it to fall apart. Letting it rest for 5 minutes allows flavors to meld and makes serving easier.
Ignoring Seasoning: Under-seasoning can leave your dish bland. Taste as you go and adjust salt and pepper according to your preference.
