Ingredients
  

Chicken
  • 4 boneless skinless chicken breasts Pat dry for better browning.
  • 2 tsp garlic powder
  • 1 tsp smoked paprika
  • 1 tsp dried thyme
  • 1 tsp dried rosemary
  • 0.25 salt and pepper to taste Use to season the chicken and mash.
  • 2 tbsp olive oil
  • 2 tbsp butter Use divided: 2 tbsp for pan sauce + 4 tbsp for mashed potatoes.
  • 4 garlic cloves, minced Use fresh garlic for the pan sauce.
  • 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 Warming helps keep mash smooth.
  • 0.25 salt, pepper, and garlic powder to taste
  • 1 fresh parsley for garnish Chop and sprinkle just before serving.

Equipment

  • 1 cast iron skillet
  • 1 sheet pan

Method
 

Make the mashed potatoes
  1. Bring a pot of salted water to a boil and cook the Yukon Gold potatoes for 15-18 minutes until fork-tender with a visible soft center.
  2. Drain the potatoes well, then mash with butter, warmed heavy cream or whole milk, salt, pepper, and garlic powder until smooth and fluffy, with no lumps remaining.
  3. Keep the mashed potatoes warm on low heat or covered so they stay creamy while you cook the chicken.
Season and sear the chicken
  1. Season the boneless skinless chicken breasts with garlic powder, smoked paprika, dried thyme, dried rosemary, and salt and pepper until both sides look evenly coated.
  2. Heat olive oil in a skillet over medium-high heat and sear the chicken for 5-6 minutes per side until golden and cooked through to 165°F, flipping once when the first side releases easily.
  3. Transfer the chicken to a plate and let any juices settle while you make the pan sauce.
Make the garlic herb pan sauce
  1. Melt 2 tablespoons butter in the same pan and cook the minced garlic for 1 minute until fragrant, stirring so it doesn’t brown.
  2. Add chicken broth to the pan and scrape up the browned bits, then simmer for 2-3 minutes until the sauce lightly thickens and looks glossy.
Plate and finish
  1. Spoon mashed potatoes onto plates and place the seared chicken on top so the chicken sits over the mash like a mound.
  2. Drizzle the garlic herb pan sauce over the chicken and lightly around the potatoes so each bite gets sauce.
  3. Garnish with fresh parsley and serve immediately for the best texture contrast.

Notes

Pro tip: pat the chicken dry and avoid moving it during the first sear—this helps you get deep golden crust. Store leftovers in the fridge up to 3 days; reheat chicken gently and add a splash of broth or milk to loosen the mash. Freezing: chicken can be frozen up to 2 months, but mashed potatoes are best fresh (freeze can turn grainy). Dietary swap: use plant-based butter and replace chicken broth with low-sodium vegetable broth for a vegetarian-friendly sauce while keeping the chicken as-is, or serve mash alongside a meat-free main if you’re avoiding meat.
