  • Skipping seasoning: Neglecting to season the sausage can result in bland flavors. Make sure to taste and adjust seasonings as needed during cooking.

  • Incorrect cooking time: Cooking for too long or too short can affect texture. Keep an eye on your casserole while it’s air frying or baking to achieve the perfect consistency.
