Top Tips for Perfecting Low Carb Philly Cheesesteak Casserole
To elevate your casserole game, consider these handy tips:
- Beef Choices: Feel free to use ground turkey or chicken as a lean alternative that maintains the flavor while reducing fat.
- Cheese Selection: Cheddar is classic, but you can experiment with provolone or mozzarella for varied flavor profiles.
- Veggie Variations: Add mushrooms for an earthy twist, or zucchini for extra nutrients.
- Avoid Overcooking: Keep an eye on your casserole to avoid over-baking the cheese, which could lead to it becoming hard instead of gooey and melty.
