Step 1

Rinse the leeks well and separate the layers to make sure there is no dirt. Slice into 1/4-inch thick half moons.

Step 2

Preheat the oven to 375 degrees.

Step 3

Mix together 1 1/4 teaspoons of salt, 1/4 teaspoon pepper and the paprika and season all sides of the chicken.

Step 4

Heat a large Dutch oven or oven safe skillet on high heat. Once hot spritz with olive oil and brown the chicken, in batches on all sides, about 5 minutes on each side, adjusting the heat as needed.

Step 5

Set aside and repeat with the remaining chicken. Set aside.

Step 6

Reduce the heat to medium-low and add the butter. When the butter starts to foam, add the leeks and cook, stirring until soft, about 6 to 8 minutes. Add the mushrooms, 1/4 teaspoon salt, stir and cook covered 5 minutes, stirring until they release their juices.

Step 7

Sprinkle the flour over them, stir in the chicken broth and the sherry and simmer for 2 to 3 minutes.

Step 8

Return the chicken to the Dutch oven, spooning the mushroom-sherry sauce over them and cook in the oven, covered, for 40 to 50 minutes, until cooked through and tender.
