Ingredients
  

Chicken and pan sauce
  • 4 boneless skinless chicken breasts
  • 2 tsp garlic powder
  • 1 tsp smoked paprika
  • 1 tsp dried thyme
  • 1 tsp dried rosemary
  • 0.25 salt and pepper to taste
  • 2 tbsp olive oil
  • 4 tbsp butter divided
  • 4 clove garlic minced
  • 0.5 cup chicken broth
Mashed potatoes
  • 2 lb Yukon Gold potatoes peeled and cubed
  • 4 tbsp butter
  • 0.5 cup heavy cream or whole milk warmed
  • 0.25 salt and pepper to taste
  • 0.5 tsp garlic powder to taste
  • 2 fresh parsley for garnish

Equipment

  • 1 cast iron skillet

Method
 

Make the mashed potatoes
  1. Boil the Yukon Gold potatoes in salted water for 15-18 minutes until fork-tender. Drain well and return to the pot.
  2. Mash the potatoes with butter, warmed heavy cream or whole milk, salt, pepper, and garlic powder until smooth and fluffy. Keep warm until ready to serve.
Sear the garlic herb chicken
  1. Season the chicken breasts with garlic powder, smoked paprika, dried thyme, dried rosemary, salt, and pepper. Rub to coat evenly for an herb crust.
  2. Heat olive oil in a cast iron skillet over medium-high heat, then sear the chicken for 5-6 minutes per side until golden and cooked through to 165°F. Remove chicken to a plate and rest briefly.
Simmer the garlic pan sauce
  1. Melt 2 tablespoons of butter in the same skillet, then cook the minced garlic for 1 minute until fragrant. Stir to prevent browning.
  2. Add chicken broth and scrape up the browned bits from the pan. Simmer for 2-3 minutes until a simple pan sauce forms.
Plate and finish
  1. Plate the mashed potatoes and place the chicken on top. Arrange chicken so it can be sliced or fanned if desired.
  2. Drizzle the pan sauce over the chicken. Garnish with fresh parsley to finish.

Notes

For the creamiest mash, warm the cream or milk before mixing so the butter emulsifies smoothly. Refrigerate leftovers in an airtight container up to 3 days; reheat gently in short microwave bursts or on the stove with a splash of milk. Freezing is not recommended for the best texture. If you want a lighter option, use whole milk instead of heavy cream for a still-rich mash without changing the method.
