Chicken & Creamy Mushroom Sauce
with Garlic Mashed Potatoes & Arugula Salad
- Wheat
- Milk
The creamy mushroom sauce that cascades over juicy seared chicken makes this meal something special! (Okay, let’s not forget the velvety sour cream and garlic mashed potatoes, which might actually be why you’re here—no judgments!). Pile those creamy potatoes on the side, add a zingy, peppery arugula salad sprinkled with Parmesan for fresh crunch and pops of color, and you’re in for a sumptuously satisfying dinner.

Cooking Steps
• Wash and dry produce. • If desired, peel potatoes. Dice potatoes 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 in Step 4.
• While potatoes cook, trim and thinly slice mushrooms (skip if your mushrooms are pre-sliced!). Quarter lemon.
• Pat chicken* dry with paper towels. Place between two large pieces of plastic wrap; 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; cook until browned and cooked through, 3-5 minutes per side. (For 4 servings, you may need to cook in batches.) Turn off heat; transfer chicken to a cutting board. Wipe out pan.
• Return pot with drained potatoes to low heat. Add half the sour cream, half the garlic powder, and 1 TBSP butter (2 TBSP for 4 servings). (You’ll use the rest of the sour cream and garlic powder in the next step.) • 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.
• Heat a drizzle of oil in pan used for chicken over medium-high heat. Add mushrooms; season with remaining garlic powder and pepper. Cook, stirring, until softened, 2-4 minutes. • Stir in stock concentrate and ¼ cup water (1/3 cup for 4 servings). 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 TBSP butter (2 TBSP for 4) until melted and combined. Season with salt and pepper.
• 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 season with more salt and pepper if desired.
• 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.
Chicken is fully cooked when internal temperature reaches 165°.

Reviews from our home cooks
Delicious new recipe! Different but simple way to cook the chicken. The mushroom gravy and mashed potatoes were enhanced with the subtle garlic flavor. The arugula salad was simple but delicious and the parm kicked it up a notch! We loved it!
Chicken and mushroom sauce were amazing. Mashed potatoes were basic, but good. Lemon and olive oil for a "salad dressing" on arugula is lazy and doesn't taste very good. Arugula has a strong flavor and needs something more to balance it. Seemed like Hello Fresh just being cheap.
This came out sooo good! The chicken was by far my favorite part of this meal. The mushroom sauce definitely had the perfect amount of savory flavor. I never thought that I would actually enjoy cooking but Hello Fresh definitely made that possible. I loved how easy and understandable the instructions were to follow. Especially how well portioned the ingredients were. Not one thing in this recipe went to waste and I was very impressed by that.
The arugula salad was a perfect side to this. When it combined with the rich and flavorful chicken, mushroom sauce and mashed potatoes, it created a perfectly balanced bite all throughout. This truly tasted high-end with so few and such simple ingredients.
Loved this dish. The mushroom sauce is So good! I love the salad with the meal, too. Our lemon was very tart. I should have taste tested before mixing with arugula.
So creamy. If you love mushrooms this is for you and you could add a little more mushrooms. The sauce is delicious, next time I plan to make a lot more
This meal is delicious, but it needs to come with more potatoes. The fresh arugula salad is wonderful, and the mushroom gravy makes the dish.
Yes on the mushrooms! 🤤 The mushroom sauce is what made this meal SO GOOD. Fresh and flavorful profile with lots of protein. A favorite.
Yummy. Mushroom gravy on potatoes is sooooo comforting. The arugula salad was just right and gave a good crunch to the meal.
I'm a chicken gal and I love garlic and mushrooms so this meal was fantastic for me! The gravy was terrific. My husband liked it too.
