How to Make Low Carb Philly Cheesesteak Casserole

Step 3: Cook the Beef
Add 2 lbs ground beef.
Break it up with your spatula as it cooks.
Season with salt and pepper.
Cook for about 7-8 minutes until browned with no pink remaining. Drain excess fat if necessary.
Step 4: Mix in Worcestershire Sauce and Cream Cheese

Reduce heat to low and add 8 oz softened cream cheese.
Stir until melted and creamy.
Step 5: Assemble the Casserole
Transfer the mixture into your prepared baking dish. Spread it evenly across the bottom.
Layer with torn pieces of 8 oz provolone cheese, then top with 1.5 cups shredded mozzarella cheese.

Common Mistakes to Avoid
When making a Low Carb Philly Cheesesteak Casserole, even small errors can impact the final dish. Here are some common mistakes to keep in mind.
Not Using Enough Seasoning: Failing to season your meat and veggies properly can lead to a bland casserole. Always taste and adjust seasonings during cooking.
Overcooking the Vegetables: Cooking vegetables for too long can result in mushiness. Aim for tender-crisp for the best texture in your casserole.
Skipping the Cream Cheese: Cream cheese is essential for achieving that creamy texture and rich flavor. Don’t omit it; instead, ensure it’s softened before mixing.
Choosing the Wrong Meat: Using lean ground beef may lead to a dry casserole. Opt for ground beef with a higher fat content (80/20 is ideal) for a moist result.
Ignoring Oven Time: Baking too long can overcook the cheese topping. Keep an eye on it and pull it out once it’s bubbly and golden.
Not Letting It Rest: Serving immediately can cause the casserole to fall apart. Allow it to rest for a few minutes to let flavors meld together.
