Chicken Bacon Ranch Gratin Potatoes Ingredients

  • Potatoes: Classic russet potatoes are perfect for this recipe. They absorb some of the creamy sauce and the flavors around them to be perfectly fluffy and tender. They will stand up to the baking time though, so they don’t get too soft.
  • Chicken: Adding cooked chicken breast to potatoes au gratin is such an easy way to make the dish more filling. Use freshly cooked chicken, canned chicken, or use up leftover chicken like Grilled Chicken or Rotisserie Chicken
  • Bacon: Cook your own bacon fresh just a few minutes before starting the rest of the recipe and it will cool while you are making the sauce. Break the bacon slices into crumbles to add the chicken casserole mixture. 
  • Ranch: For the Ranch dressing mix, you can just buy a packet at the store. Or, use pantry items you probably already have to make your own Ranch Dressing Mix. You could also easily switch it up to Italian chicken or Taco chicken by swapping in a different seasoning packet.
  • Cheese: Buttery, melty cheddar cheese is the perfect match to go with the delicious ranch flavoring. You want to add the cheese during the last 10 minutes so it melts but doesn’t get crunchy or burn.

Kitchen Tools & Equipment

  • Baking Dish: This casserole is baked in a standard 9×13-inch baking dish. It makes it a crowd sized dish that won’t take too long to cook through. 
  • Skillet: The sauce is made in a skillet so that it thickens nicely and stays together. It’s important to cook the sauce while slowly adding the cream so it doesn’t separate while baking.

FAQ for Chicken Bacon Ranch Gratin Potatoes

Can I use raw chicken or uncooked bacon?

No, you will want to use cooked bacon and cooked chicken breast pieces. You won’t get crispy bacon if you start with it uncooked and your chicken may turn out rubbery or not as tender.

Do I have to use chicken breast?

You can absolutely substitute boneless, skinless chicken thighs for the boneless chicken breasts, you just want to make sure it’s cooked and without bones or skin. You could also use leftover chicken like rotisserie chicken.
