Ingredients
  

chicken
  • 4 boneless skinless chicken breasts
  • 2 tsp garlic powder
  • 1 tsp smoked paprika
  • 1 tsp dried thyme
  • 1 tsp dried rosemary
  • salt to taste
  • pepper to taste
  • 2 tbsp olive oil
  • 4 tbsp butter divided
  • 4 cloves garlic minced
  • 1 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
  • salt to taste
  • pepper to taste
  • garlic powder to taste
  • 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, keeping the pot at a steady simmer. Visual cue: the cubes should slide off a fork easily.
  2. Drain the potatoes and mash with butter and warmed heavy cream or whole milk until smooth and fluffy. Visual cue: the mash should look creamy with no large lumps.
  3. Season the mashed potatoes with salt, pepper, and garlic powder to taste, then cover and keep warm until plating. Visual cue: a gentle steam should remain, indicating it’s still hot.
Cook the herb-crusted chicken
  1. Season the chicken breasts with garlic powder, smoked paprika, dried thyme, dried rosemary, salt, and pepper until evenly coated. Visual cue: spices should cling in a dry, speckled layer.
  2. Heat olive oil in a cast iron skillet over medium-high heat and sear the chicken for 5-6 minutes per side until golden and cooked through to 165°F. Visual cue: juices should run clear and the crust should be browned.
  3. Remove the chicken to a plate while you make the pan sauce. Visual cue: the browned bits should remain in the skillet for flavor.
Make the garlic herb pan sauce and serve
  1. Melt 2 tablespoons butter in the same skillet, scraping up browned bits from the bottom. Visual cue: the fond should loosen and turn glossy.
  2. Cook the minced garlic for 1 minute, stirring, until fragrant. Visual cue: you should smell garlic strongly without browning too far.
  3. Add chicken broth and simmer for 2-3 minutes until a simple pan sauce forms. Visual cue: the liquid should lightly thicken and coat the back of a spoon.
  4. Plate the mashed potatoes and place the chicken on top. Visual cue: aim for a neat mound of mash with chicken centered.
  5. Drizzle the pan sauce over the chicken. Visual cue: sauce should streak across the chicken and lightly pool on the potatoes.
  6. Garnish with fresh parsley before serving. Visual cue: bright green flecks over the top make the dish stand out.

Notes

For the smoothest mashed potatoes, make sure the boiled potatoes are fully fork-tender before mashing and keep the cream or milk warmed so they blend quickly. Refrigerate leftovers in an airtight container for up to 3 days; reheat gently in a skillet or microwave until hot (add a splash of milk if needed). Freezing is not recommended for best texture. For a dairy swap, use unsweetened plant-based butter and whole-milk-style oat cream (or similar) to create a similar creamy mash and sauce.
