    • Always cook bacon, sausage, and veggies beforehand.
  • Secret #4: Balance Your Dairy
    • Too much milk = soggy casserole. Keep it balanced.
  • Secret #5: Layer Properly
    • Even layering ensures every bite is flavorful.
  • Secret #6: Let It Rest
    • After baking, let it sit for 5-10 minutes.
