Step 1

Preheat oven to 425°F. Sprinkle chicken evenly with 1 1/4 teaspoons salt and 1/2 teaspoon pepper. Heat oil in a 12-inch ovenproof skillet over medium. Cook chicken, skin side down, until skin is golden brown and crispy, 15 to 18 minutes. Flip the chicken breasts and cook skin side up, until a thermometer inserted in thickest portion of chicken registers 160°F, about 15 minutes. Transfer to a plate. Reserve 1 Tablespoons of drippings in skillet.

Step 2

Heat reserved drippings in skillet over medium-high. Add spring onion; cook, stirring often, until softened, about 1 minute. Add wine (mixture will immediately come to a simmer). Simmer over medium-high, stirring occasionally to loosen browned bits on bottom of skillet, until reduced by about half, 1 to 2 minutes. Add stock; cook, stirring occasionally, until mixture has reduced to about 2/3 cup and just barely coats back of a spoon, 4 to 6 minutes. Reduce heat to low; stir in crème fraîche until just melted, about 30 seconds. Remove from heat; stir in herbs and lemon juice. Season to taste with salt and black pepper. Serve alongside cooked chicken.
