Tips for Perfect Keto Philly Cheesesteak Casserole

1. Slice the Beef Thinly : Thinly sliced beef cooks quickly and stays tender. Ask your butcher to slice it for you, or partially freeze the meat before slicing.
2. Don’t Overcook the Veggies : Cauliflower rice or zucchini noodles should retain some texture to avoid becoming mushy.
3. Customize the Cheese : Use your favorite cheese blend to suit your taste preferences.
4. Store Properly : Keep leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving.
