04Add the rest of the clarified butter to the pan along with the shallots, drained morels, and garlic. Saute over medium heat for 2 minutes, tossing and stirring constantly. Pour the Madeira into the pan and reduce the liquid by half over high heat, 2 to 4 minutes. Add the creme fraiche, cream, lemon juice, 1 teaspoon salt, and 3¿4 teaspoon pepper. Boil until the mixture starts to thicken, 5 to 10 minutes. Pour the sauce over the chicken and bake for 12 minutes, or until the chicken is heated through. To make ahead, refrigerate the chicken and sauce in the casserole and reheat slowly on top of the stove.
