# Ingredient List:

→ Chicken & Mushroom Sauce

01 - 4 boneless, skinless chicken breasts
02 - Salt and freshly ground black pepper, to taste
03 - 2 tablespoons olive oil
04 - 1 tablespoon unsalted butter
05 - 9 ounces cremini or button mushrooms, sliced
06 - 3 garlic cloves, minced
07 - 1 small shallot, finely chopped
08 - 1/2 cup chicken broth (gluten-free if needed)
09 - 3/4 cup heavy cream
10 - 1 teaspoon Dijon mustard
11 - 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried thyme)
12 - 2 tablespoons fresh parsley, chopped

→ Crispy Herb Potatoes

13 - 1 3/4 pounds baby potatoes, halved
14 - 2 tablespoons olive oil
15 - 1 teaspoon dried rosemary
16 - 1 teaspoon dried thyme
17 - 1 teaspoon garlic powder
18 - Salt and pepper, to taste
19 - 2 tablespoons fresh parsley, chopped (for serving)

# Steps:

01 - Preheat oven to 425°F. Line a large baking tray with parchment paper.
02 - Toss halved baby potatoes with 2 tablespoons olive oil, rosemary, thyme, garlic powder, salt, and pepper. Spread in a single layer on the prepared tray and roast for 30 to 35 minutes, turning halfway through, until crispy and golden brown.
03 - While the potatoes roast, season chicken breasts generously on both sides with salt and freshly ground black pepper.
04 - Heat 2 tablespoons olive oil in a large skillet over medium-high heat. Sear chicken breasts 4 to 5 minutes per side until golden and nearly cooked through. Remove from skillet and set aside.
05 - Reduce heat to medium. Add 1 tablespoon butter to the skillet, then sauté mushrooms and shallot for 4 to 5 minutes until mushrooms soften and begin to brown. Add minced garlic and cook 1 additional minute.
06 - Pour in chicken broth to deglaze, gently scraping up browned bits from the bottom. Simmer until liquid reduces by half, about 3 to 4 minutes.
07 - Stir in heavy cream, Dijon mustard, and thyme. Return chicken breasts to the skillet and simmer for 6 to 8 minutes until sauce thickens slightly and chicken is cooked through completely.
08 - Taste sauce and adjust seasoning as needed. Garnish with chopped fresh parsley. Serve chicken with creamy mushroom sauce alongside the crispy herb-roasted potatoes, sprinkling additional fresh parsley over the potatoes before serving.

# Expert Advice:

01 -
  • The sauce reduces into something so velvety and rich that people will assume you spent all afternoon at the stove.
  • Those herb roasted potatoes crisp up beautifully in the oven while you focus on the chicken, so everything lands on the table at the same time without any juggling.
02 -
  • Do not rush the mushroom browning because skipping this step leaves you with boiled gray slices instead of deeply flavored golden pieces that carry the whole sauce.
  • Resist the urge to crank the heat when the cream goes in because high heat can cause it to break and turn grainy instead of smooth and luxurious.
03 -
  • Let the chicken rest for five minutes after searing before returning it to the sauce so the juices redistribute instead of running out and diluting everything.
  • Tossing the potatoes with the oil and seasonings in a bowl first ensures every single piece gets evenly coated, which is the real secret to consistently crispy edges.
