Chicken Supreme with Mushroom and Shallot Ragout

Remove chicken breasts from refrigerator 20 minutes before cooking. Pat each piece completely dry with paper towels. Season generously with salt and black pepper on both sides, then dust lightly with flour, shaking off any excess.

In a large heavy-bottomed skillet or frying pan, heat 3 tablespoons of butter over medium-high heat until the foam subsides. The butter should be hot enough that a small drop of water sizzles immediately upon contact.

Carefully lay the chicken breasts in the pan, presentation side down. Sear without moving for 4-5 minutes until a deep golden crust forms. Flip and cook another 3-4 minutes. The chicken should feel firm but yield slightly when pressed. Transfer to a plate and tent with foil to rest.

In the same pan over medium heat, add the additional 2 tablespoons of butter. Once melted, add the diced shallots and yellow onion. Cook, stirring occasionally with a wooden spoon, for 5-6 minutes until softened and beginning to turn translucent.

Add the minced garlic and thyme sprigs. Cook for 1 minute until fragrant, being careful not to let the garlic burn. This is where the fond from the chicken becomes your friend—scrape it up as you stir.

Add the sliced mushrooms to the pan in a single layer. Do not stir immediately—let them sear and release their moisture. After 3-4 minutes, toss and continue cooking until the mushrooms are golden brown and any liquid has evaporated, about 8-10 minutes total.

Deglaze the pan with the red wine vinegar, scraping up every bit of fond from the bottom. Let the vinegar reduce by half, about 1-2 minutes. You should smell the acidity mellow into something rounder.

Pour in the chicken broth and bring to a gentle simmer. Let it reduce by one-third, approximately 3-4 minutes. Stir in the heavy cream and continue simmering until the sauce coats the back of a spoon nicely, about 3 more minutes. Remove the thyme sprigs.

Return the seared chicken breasts to the pan, nestling them into the ragout. Cover and simmer on medium-low heat for 8-10 minutes until the chicken reaches an internal temperature of 165°F (74°C) in the thickest part. The sauce will have thickened further.

Transfer each chicken supreme to a warm plate, spooning the mushroom and shallot ragout generously alongside. Finish with a sprinkle of fresh chopped parsley and, if desired, a small knob of cold butter swirled into the sauce at the last moment for extra gloss and richness.
