Ingredients

  • 2 lb Yukon gold potatoes, peeled and chopped
  • 1½ tsp salt, divided
  • 1½ lb chicken breast tenders or boneless chicken pieces
  • 1 tsp black pepper, divided
  • 1 tsp smoked paprika
  • 1 tsp garlic powder
  • 2 tbsp olive oil, divided
  • 4 tbsp butter, divided
  • ½ cup warm milk or cream
  • 1 medium yellow onion, sliced
  • 8 oz mushrooms, sliced
  • ½ red bell pepper, sliced
  • ½ yellow bell pepper, sliced
  • ½ green bell pepper, sliced
  • 2 garlic cloves, minced
  • ½ cup chicken broth
  • 2 tbsp chopped fresh parsley

Instructions

  • Prepare the potatoes: Place peeled and chopped Yukon gold potatoes in a pot of salted water (use 1 tsp salt). Boil for 15–20 minutes until tender.
  • Drain and mash: Drain the potatoes, return to the pot for 1 minute to steam-dry. Mash with 2 tbsp butter, warm milk/cream, and ½ tsp salt until creamy.
  • Season the chicken: Pat chicken dry. Toss with ½ tsp salt, ½ tsp black pepper, smoked paprika, garlic powder, and 1 tbsp olive oil.
  • Cook the chicken: In a skillet, cook chicken over medium-high heat for 4–5 minutes per side. Transfer to a plate and keep warm.
  • Sauté the vegetables: In the same skillet, add remaining 1 tbsp olive oil and 1 tbsp butter. Cook onion, mushrooms, and bell peppers for 7–9 minutes until softened and lightly browned.
  • Add garlic and broth: Stir in minced garlic, cook for 1 minute. Pour in chicken broth, simmer for 2–3 minutes until slightly thickened.
  • Finish the sauce: Stir in 1 tbsp butter and chopped parsley. Adjust seasoning with remaining salt and pepper if needed.
  • Serve: Spoon creamy mashed potatoes onto plates, top with cooked chicken, and generously ladle the vegetable sauce over the chicken.

Notes

Use Yukon gold potatoes for a naturally buttery flavor. Substitute chicken pieces for even cooking. Leftovers can be refrigerated for up to 2 days.
Increase the smokiness with a pinch of cayenne pepper or chili flakes.
