Instructions
Season and Sear the Chicken
Pat the chicken thighs dry with paper towels. Season both sides generously with salt, pepper, garlic powder, and smoked paprika. Dust the skin side lightly with flour.
Heat the cast iron skillet over medium-high heat. Add the butter and bacon grease. When the butter is melted and starting to foam, place the chicken thighs skin-side down in the skillet. Do not move them for 5-7 minutes, until the skin is deep golden and crispy.
Flip the thighs and cook for another 3-4 minutes. Remove the chicken to a plate. It does not need to be cooked through — it will finish in the sauce.
Build the Sauce
In the same skillet with the drippings, add the diced onion. Cook for 2-3 minutes, stirring occasionally, until softened and starting to turn translucent.
Add the sliced mushrooms in a single layer. Let them cook undisturbed for 3-4 minutes until they release their liquid and develop golden-brown edges. Stir, then cook another 2 minutes.
Add the minced garlic, thyme, and red pepper flakes if using. Stir constantly for about 30 seconds until fragrant.
Pour in the chicken broth, scraping up all the browned bits from the bottom of the skillet with your wooden spoon. Let it simmer for 2 minutes to reduce slightly.
Stir in the heavy cream and bring to a gentle simmer. Cook for 3-4 minutes, stirring occasionally, until the sauce thickens enough to coat the back of a spoon.
Finish the Dish
Add the fresh spinach in large handfuls, stirring and letting each handful wilt before adding the next. This takes about 2 minutes total.
Stir in the Parmesan cheese until melted and incorporated into the sauce.
Nestle the seared chicken thighs back into the skillet, skin-side up, spooning some sauce over the tops but keeping the skin exposed. Reduce heat to medium-low, cover, and simmer for 12-15 minutes until the chicken reaches an internal temperature of 165°F.
Remove from heat, squeeze fresh lemon juice over the top, and let rest for 5 minutes before serving.
