Cheesy Bourbon Potatoes Au Gratin takes sliced potatoes and covers them in a rich, creamy cheese sauce made with poblano, bourbon, and cheese.


Units Scale
  • 3 lb Yukon gold potatoes
  • 1 poblano pepper, finely chopped
  • 1/2 white onion, finely chopped
  • 1/3 cup bourbon whiskey
  • 2 cups heavy whipping cream
  • 8 oz chipotle gouda cheese block, cubed
  • 8 oz muenster cheese block, cubed
  • 1 cup shredded extra sharp cheddar
  • 1 1/2 cup shredded mozzarella cheese
  • 1 tbsp minced garlic
  • 1 tsp paprika
  • 1 tsp dried basil
  • 1 tsp black pepper
  • 1/2 tsp ground thyme
  • 1 1/2 tsp pink sea salt, divided
  • 1/4 tsp red pepper flakes
  • 1 tsp all-purpose flour
  • 3 tbsp butter, divided


  1. Rinse and dry the potatoes. Slice them into 1/8-inch thick slices. Season evenly with 1 tsp of salt.
  2. Roast the poblano pepper directly over an open flame until charred on both sides. Remove the char, stem, and seeds and finely chop.
  3. Add 1 tbsp of butter to a large saucepot at medium heat. Add chopped onions and cook until the onions are translucent. Add the chopped poblano, 2 tbsp of butter, 1 tsp of flour, and minced garlic. Stir together.
  4. Pour in the bourbon. Allow it to reduce for 3-5 minutes. Add the chopped chipotle gouda and chopped muenster cheese. Cover and allow the cheese to melt.
  5. Add 1 cup shredded extra sharp cheddar cheese, 1 cup mozzarella cheese, smoked paprika, salt, pepper, ground thyme, red pepper flakes, dried basil, and heavy cream. Stir, cover, and lower the heat. Continue to stir often until the consistency is smooth.
  6. Spread a little cheese sauce on the bottom of the baking dish and layer the potato slices. Top off with more cheese sauce. Repeat this step until all the potatoes are layered and the cheese is completely covering the potatoes.
  7. Bake for 1 hour at 350 degrees, then remove from oven and top off with remaining cheeses and chives. Bake for an additional 15 minutes at 350 degrees.
  8. Allow to cool, then serve.
