Heat a medium/large skillet (oven safe) over medium high heat. Add 2 tablespoons butter and allow to melt, making sure the entire base of the skillet is coated.
3 tablespoons salted butter
Add the chicken skin side down, and sear for 3-4 minutes or until golden brown.
Flip and sear other side. Remove chicken from the skillet and set aside.
Make the Sauce:
Return skillet to the heat and add additional 1 tablespoon butter. Allow to melt, stirring and deglazing the pan.
Add the garlic and cook for 1-2 minutes until fragrant.
3 cloves minced garlic
Stir in the chicken broth, heavy cream, parmesan, lemon juice, and thyme. Stir to fully combine. Bring to a boil and then reduce to a simmer.
½ cup low-sodium chicken broth, 1 cup heavy cream, ½ cup grated parmesan cheese, ¼ cup fresh lemon juice, 1 teaspoon fresh thyme leaves
Allow sauce to thicken for 5 minutes and then stir in spinach leaves. Stir to wilt leaves slightly but not fully.
5 ounces baby spinach
Bake:
Add chicken back to skillet and bake the entire pan in the oven for 25 minutes, or until internal chicken temperature reaches 165-175°F.
Garnish with lemon slices and fresh thyme. Serve over rice, pasta, mashed potatoes, or alone. Enjoy!

Notes
*I prefer bone-in, skin-on chicken thighs for this recipe, as they lead to the juiciest and most flavor chicken. Boneless thighs can be used--just decrease the baking time slightly (about 20 minutes).**Heavy cream works best for this lemon butter sauce. Bring it to room temp so it doesn't curdle when added to heat. If using half-n-half or a dairy alternative, it will likely create a less silky consistency.***Swap spinach for arugula or another delicate green; or skip it if you prefer.Tips:
I recommend using a cast iron skillet for one pan recipe like this. It holds and distributes heat evenly, plus it's oven-safe! If you don't have one, another oven-safe skillet can be used.
Let chicken thighs come to room temp before cooking.
Take a minute to deglaze the pan after cooking the chicken. Getting those browned bits mixed into the sauce will add depth to the flavor.
The chicken is done when the internal temperature reaches 165°F; but because this is dark meat, I recommend cooking it to 170-175°F for the juiciest results.
Storage: Store creamy lemon butter chicken in an airtight container in the refrigerator for 3 days, or freeze for 3 months.
