Prep once and relax: this is freezer-friendly (freeze raw ingredients in a bag for up to 3 months). Use cream cheese or Greek yogurt for creaminess. If casserole is too runny, remove lid for the last 30 minutes or stir in 1 Tbsp cornstarch mixed with 1 Tbsp water. Add green chilies or jalapeño for heat. Use corn tortillas for a gluten-free option.
