Set your oven to 375F and allow to preheat.
Thoroughly wash the chicken thighs and dry with a paper towel.
In a bowl, mix the paprika powder, minced garlic, pepper, and salt.
Season the chicken thigh with the mixed spices.
Set your stove to medium heat and place a skillet on it. Put in some butter and allow to melt. Stir fry the chicken until it turns an even golden brown on all sides.
While the chicken is still sautéing, pour in the chicken broth, heavy cream, thyme, and lemon juice. For 10 minutes, allow to boil and cook with the heat set at medium.
Lastly, add the baby spinach, cover the pot with a lid, and allow it to cook for 3 extra minutes then put off the stove.
Empty the contents of the pot into a baking dish. Sprinkle a good quantity of Parmesan cheese on the cooked chicken and allow to bake in the preheated oven for 10 minutes. Remove from oven when it is properly cooked.
Best served hot or very warm with some lettuce salad to go with it.
