Pro Tips for 5-Ingredient Casserole Success

  1. Use Rotisserie Chicken: Save 15 minutes of prep time by picking up a cooked rotisserie chicken from the grocery store to shred for your casseroles.
  2. Grate Your Own Cheese: Pre-shredded bag cheese is coated in cellulose to prevent sticking, which keeps it from melting as smoothly. Grating your cheddar fresh makes for a much creamier sauce.
  3. Add Toppings Last: If your casserole features crunchy elements like crushed potato chips, fried onions, or Ritz crackers, add them during the last 10 minutes of baking to keep them from over-browning or getting soggy.
