Instructions

  1. Wash and dry produce. If desired, peel potatoes and dice into ½-inch pieces. Place in a medium pot with enough salted water to cover by 2 inches. Bring to a boil and cook until tender, 12-15 minutes. Reserve ½ cup potato cooking liquid; drain and return potatoes to pot. Keep covered off heat until ready to mash.
  2. While potatoes cook, trim and thinly slice mushrooms. Quarter the lemon.
  3. Pat chicken dry with paper towels. Place between two large pieces of plastic wrap and pound with a mallet or heavy-bottomed pan until about ½ inch thick. Season all over with salt and pepper. Sprinkle chicken all over with flour, pressing to adhere; shake off any excess. Heat a drizzle of oil in a large pan over medium-high heat. Add coated chicken and cook until browned and cooked through, 4-6 minutes per side. Transfer chicken to a cutting board and wipe out the pan.
  4. Return the pot with drained potatoes to low heat. Add half the sour cream, half the garlic powder and 1 tablespoon butter. Mash until smooth and creamy, adding splashes of reserved potato cooking liquid as needed. Season with salt and pepper. Keep covered off heat until ready to serve.
  5. Heat a drizzle of oil in the same pan over medium-high heat. Add mushrooms and season with remaining garlic powder and pepper. Cook, stirring, until softened, 2-4 minutes. Stir in stock concentrate and ¼ cup water. Bring to a boil, then reduce to a low simmer. Cook, stirring, until slightly thickened, 2-3 minutes. Remove from heat. Stir in remaining sour cream and 1 tablespoon butter until melted and combined. Season with salt and pepper.
  6. In a large bowl, toss arugula with a drizzle of olive oil, a squeeze of lemon juice, salt and pepper until evenly coated. Taste and adjust seasoning if desired.
  7. Divide chicken, mashed potatoes and salad between plates. Spoon mushroom sauce over chicken and mashed potatoes. Sprinkle Parmesan over salad. Serve with remaining lemon wedges on the side.

Recipe Tips

For extra creamy mashed potatoes, use a potato ricer or mash while still hot.

If the sauce is too thick, thin with a splash of water or chicken broth.

Let the chicken rest for a few minutes after cooking to keep it juicy.

FAQ

Can I use chicken breasts instead of cutlets?

Yes, simply slice chicken breasts in half horizontally or pound them to an even thickness for quicker cooking.

What can I substitute for sour cream?

Greek yogurt or crème fraîche work well as substitutes for sour cream in both the sauce and mashed potatoes.

How do I store leftovers?

Store chicken, potatoes and salad separately in airtight containers in the refrigerator for up to 3 days. Reheat gently.
