1 hour 15 minutes
Serves 4-8
INGREDIENTS:
  • 1 1/2 lb Yukon gold potatoes, sliced crosswise into 1/8" thick rounds
  • 1 (1 lb) bulb fennel, stalks and root end trimmed and bulb sliced lengthwise 1/8" in thick, fronds reserved
  • 1 Tbsp olive oil
  • Salt and freshly ground pepper
  • 8 (about 3 lb) bone-in, skin-on chicken thighs
  • 4 oz Gruyere cheese, finely grated
  • 1 (12 oz) can beer, such as lager or pilsner
  • 3 Tbsp coarse mustard
  • 1 tsp sugar
  • 2 Tbsp butter
DIRECTIONS:

Preheat oven to 450° and set rack in upper-middle position.

In a bowl, toss potatoes and fennel with olive oil. Season lightly with salt and pepper.

On a rimmed baking sheet, shingle potatoes and fennel in even layers, covering the surface of the baking sheet.

Liberally season chicken with salt and pepper. Arrange chicken along outer edges of the sheet pan, making sure there’s a thigh covering every corner. Bake chicken and vegetables until chicken skin is golden and crispy, about 45 minutes. Transfer chicken thighs to warm serving platter or plates and keep warm.

Scatter grated cheese all over the surface of the potatoes and fennel. Increase heat to broil and broil until cheese is melted and turning lightly golden in spots and vegetables are crispy and brown on the surface, about 5 minutes.

Using a slotted spatula, carefully transfer potatoes and fennel to serving platter or plates, allowing excess fat to drain before each transfer. You can stack vegetables on top of each other to create a taller gratin-like structure. Keep warm.

Set baking sheet over stovetop burner set to medium-high heat. Cook, moving the baking sheet around as needed, to brown remnant cooking juices on the bottom of the baking sheet.

Drain excess fat on the baking sheet into a small heatproof bowl. Return baking sheet to heat and immediately add beer. Increase heat to high and bring beer to boil. Using a wooden spoon, scrape up the browned bits on the bottom of the baking sheet.

Stir in mustard, using wooden spoon. Work mustard into the beer while carefully shaking the baking sheet to mix the thin layer of liquid on it. Continue to cook, stirring and gently shaking, until reduced by about half. Stir in sugar. Turn off heat and melt in butter, stirring and shaking the whole time to emulsify it into the sauce. Taste, then season with salt and/or more sugar, as desired. Pour sauce into serving boat. Garnish potatoes with reserved fennel fronds and serve.
