Ingredients

Scale

Main Protein:

  • 2 pounds boneless, skinless chicken thighs or breasts

Potatoes and Dairy:

  • 3 pounds Russet or Yukon Gold potatoes
  • 2 cups shredded sharp cheddar cheese
  • 1 cup shredded Monterey Jack or mozzarella cheese
  • ½ cup grated Parmesan cheese
  • ½ cup unsalted butter
  • ½ cup whole milk or half-and-half
  • ¼ cup sour cream or cream cheese
  • 2 cups buttermilk

Seasoning and Coating:

  • 2 large eggs
  • 2 cups Panko breadcrumbs
  • 1 ½ cups all-purpose flour
  • ½ cup cornstarch
  • ½ cup crispy fried onions or additional Panko breadcrumbs
  • 2 tablespoons fresh chives
  • 2 teaspoons smoked paprika
  • 1 tablespoon hot sauce
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1 teaspoon salt
  • ½ teaspoon cayenne pepper
  • ½ teaspoon black pepper
  • 46 cups vegetable oil, canola oil, or peanut oil

Instructions

  1. Scrub 3 pounds of potatoes clean, then peel and dice into 1-inch cubes for consistent cooking.
  2. Transfer potato cubes to a large pot, cover completely with cold water, and add 1 teaspoon salt.
  3. Bring potatoes to a rolling boil over high heat, cooking for 15-18 minutes until they break apart easily with a fork.
  4. Drain potatoes thoroughly in a colander, then return them to the warm pot.
  5. Incorporate ½ cup butter, ½ cup whole milk, ¼ cup sour cream, and your seasonings into the potatoes.
  6. Mash the potatoes until they reach a silky, lump-free consistency, then gently stir in 2 tablespoons fresh chives.
  7. Submerge 2 pounds of chicken in 2 cups buttermilk mixed with 1 tablespoon hot sauce in a deep container.
  8. Refrigerate the chicken for 1-2 hours to allow the buttermilk to tenderize and flavor the meat.
  9. Create your seasoned coating by blending 1 ½ cups flour, ½ cup cornstarch, and all specified spices in a shallow dish.
  10. Crack 2 large eggs into a separate bowl and whisk until smooth.
  11. Pour 2 cups Panko breadcrumbs into a third container for final coating.
  12. Extract chicken from buttermilk, allowing excess liquid to drip away.
  13. Coat each chicken piece first in seasoned flour, then dip in egg wash, and finally roll in Panko breadcrumbs.
  14. Heat 4-6 cups oil in a deep skillet to exactly 350°F for optimal frying temperature.
  15. Gently lower chicken pieces into hot oil, frying 4-5 minutes per side until they turn a deep golden brown and reach an internal temperature of 165°F.
  16. Transfer fried chicken to a wire rack to preserve its crispy exterior.
  17. Set your oven to preheat at 375°F.
  18. Spread the creamy mashed potatoes evenly across a 9×13 inch baking dish.
  19. Arrange the crispy chicken pieces directly on top of the potato layer.
  20. Generously sprinkle 2 cups cheddar, 1 cup Monterey Jack, and ½ cup Parmesan cheese over the chicken.
  21. Finish by scattering ½ cup crispy fried onions or extra Panko breadcrumbs across the top.
  22. Slide the casserole into the oven, baking for 15-20 minutes until the cheese bubbles and turns a beautiful golden color.
  23. Allow the casserole to rest for 10 minutes, which helps the cheese set and makes serving easier.

Notes

  • Marinate chicken longer for deeper flavor, up to 4 hours or overnight in the refrigerator.
  • Choose high-starch potatoes like Russet or Yukon Gold for the creamiest mashed potato base.
  • Pat chicken pieces completely dry before dredging to ensure maximum crispiness and better breading adherence.
  • For a gluten-free version, substitute all-purpose flour with rice flour and use gluten-free breadcrumbs.
