Common Mistakes to Avoid
When preparing your Low Carb Philly Cheesesteak Casserole, it’s easy to make some common mistakes. Here are a few to keep in mind:

- Using Cold Cream Cheese: Adding cold cream cheese can cause clumps in your mixture. Soften it at room temperature first for a smooth texture.
