Method
Pat the chicken breasts dry with paper towels. Season evenly on all sides with kosher salt and freshly ground black pepper.
Heat olive oil in a stainless steel skillet over medium-high heat until shimmering. Add the chicken breasts and sear until deeply golden brown and cooked to an internal temperature of 74C/165F, about 6 to 8 minutes per side. Use tongs to remove the chicken to a plate to rest.
Lower the heat to medium. Add the sliced mushrooms to the skillet in an even layer. Let them cook undisturbed for 3 minutes to brown, then stir. Add the diced shallot and minced garlic, cooking for 2 more minutes until softened and aromatic.
Pour the dry sherry and sherry vinegar into the hot skillet. Use a wooden spoon to vigorously scrape up any browned bits stuck to the bottom of the pan.
Stir in the chicken stock, honey, and fresh thyme leaves. Bring the mixture to a simmer and allow it to reduce by half until it thickens slightly into a syrupy consistency, about 4 to 5 minutes.
Remove the skillet from the heat. Add the cold cubed butter and swirl the pan constantly until the butter melts and emulsifies into a glossy sauce. Return the chicken and any resting juices to the pan, turning to coat in the glaze. Serve immediately.
Chef's Notes
- Using a stainless steel pan is crucial for this recipe. Non-stick pans will not develop the rich browned layer on the bottom (the fond) which gives the sherry sauce its intense savory depth.
- Swirling cold butter into the sauce off the heat is a technique called monter au beurre. It emulsifies the fat into the liquid without breaking, creating a luxurious mouthfeel.
- Do not salt the mushrooms when they first go into the pan. Salt draws out moisture, causing them to steam rather than sear.
Storage
Refrigerator: 3 days — Store chicken and sauce in an airtight container. Mushrooms may darken.
Freezer: 1 month — Sauce may separate upon thawing; reheat gently and whisk to re-emulsify.
Reheating: Reheat gently in a covered skillet over medium-low heat until warmed through to prevent overcooking the chicken.
