Step-by-Step Instructions

Step 1: Make the Compound Butter

In a small bowl, mix softened butter with parsley, chives, rosemary/thyme, garlic, lemon juice (if using), salt, and pepper.
Spoon onto plastic wrap, roll into a log, and refrigerate while you cook (or just chill in a bowl).

Step 2: Boil the Potatoes

Place chopped potatoes in a pot and cover with cold water. Add 1 teaspoon salt.
Bring to a boil and cook 15–18 minutes until fork-tender. Drain well.

Step 3: Mash Until Creamy

Mash potatoes with butter, warm milk, and sour cream (if using). Season with salt and pepper.
Keep warm on low heat, adding a splash of milk if needed.

Step 4: Season the Chicken

Pat chicken dry. Season both sides with salt, pepper, garlic powder, and Italian seasoning.

Step 5: Pan-Sear the Chicken

Heat olive oil in a large skillet over medium-high heat. Add chicken and sear 5–7 minutes per side (depending on thickness) until golden and cooked through (165°F / 74°C).
Optional: add 1 tablespoon butter, smashed garlic, and herbs during the last 2 minutes and spoon the buttery pan juices over the chicken.

Step 6: Rest and Serve

Let chicken rest 5 minutes. Spoon mashed potatoes onto plates, top with chicken, and add a slice or spoonful of compound butter over the hot chicken so it melts beautifully.

Serving Suggestions

  • Serve with roasted green beans, asparagus, or broccoli for a complete plate.
  • Add a simple side salad with lemon vinaigrette to balance the richness.
  • Spoon extra pan juices over the potatoes for even more flavor.
  • Garnish with fresh parsley and lemon wedges for a fresh finish.
  • Pair with crusty bread to mop up melted compound butter.
