Pat the chicken thighs dry with paper towels—this helps the skin crisp up better.

Season both sides generously with salt and black pepper.

Heat olive oil in a large skillet or Dutch oven over medium-high heat.

Place chicken thighs skin-side down in the hot pan. Let them sear undisturbed for 5–7 minutes, until the skin is golden and crispy.

Flip and sear the other side for 3–4 minutes, then transfer to a plate. Don’t worry about cooking them through yet—they’ll finish in the sauce.

Pro Tip: Don’t overcrowd the pan—sear in batches if needed to avoid steaming the chicken.

Reduce the heat to medium. Add the butter to the same pan.

Once melted, stir in the sliced onions with a pinch of salt.

Cook the onions slowly, stirring every few minutes, until they’re soft, golden, and deeply caramelized—this usually takes 15–20 minutes.

If the pan gets too dry, splash in a tablespoon of water to deglaze.

Pro Tip: Be patient—caramelizing onions is low and slow. Don’t rush it; the flavor payoff is worth it.

Once the onions are golden and jammy, add the sliced mushrooms.

Cook for 5–7 minutes, stirring occasionally, until they release their moisture and start to brown.

Add the minced garlic and sauté for another 30 seconds until fragrant—don’t let it burn.

Pour in the apple cider and chicken broth, stirring well to scrape up any browned bits from the bottom of the pan.

Stir in the Dijon mustard and thyme.

Taste the liquid and adjust seasoning if needed (a pinch of salt, a bit more mustard, etc.).

Bring everything to a gentle simmer.

Pro Tip: Deglazing the pan lifts all that caramelized flavor into the sauce—don’t skip it!

Nestle the seared chicken thighs back into the pan, skin-side up. The liquid should come about halfway up the sides of the chicken.

Cover with a lid (or foil if your pan doesn’t have one), reduce the heat to low, and let it simmer gently for 25–30 minutes.

Remove the lid and simmer uncovered for an additional 10–15 minutes to thicken the sauce slightly and deepen the flavor.

Pro Tip: To get extra-crispy skin, place the uncovered pan under a broiler for 2–3 minutes at the end (if your pan is oven-safe).

Optional: Stir in a splash of apple cider vinegar at the end for brightness.

Sprinkle chopped fresh parsley or extra thyme on top before serving.

Spoon the onions, mushrooms, and sauce over each chicken piece when plating.
