450 g Brussels sprouts, trimmed and halved
2 large sweet potatoes, cut into wedges
1 medium sweet onion, cut into wedges
30 ml olive oil, divided
1.25 tsp kosher salt, divided
0.75 tsp ground black pepper, divided
4 (140 g) bone-in, skin-on chicken pieces
30 g grainy mustard
20 ml champagne vinegar
15 ml maple syrup
0.5 tsp kosher salt
0.25 tsp cayenne pepper
Step 1
Preheat the oven to 220°C (425°F) and line a rimmed baking sheet with foil.
Step 2
Prepare the veggies and chicken: Toss Brussels sprouts, sweet potatoes, and onion on the prepared baking sheet with 15 ml of oil, 1 tsp of salt, and 0.5 tsp of pepper; spread them out in a single layer.
Step 3
Sprinkle the chicken with the remaining 1/4 tsp of salt and 1/4 tsp of pepper, and place them, skin-side up, among the veggies on the baking sheet. Brush the remaining oil on the chicken skin.
Step 4
Roast in the preheated oven for about 45 minutes until the chicken is cooked through, golden, and crispy. An instant-read thermometer inserted near the bone should read 74°C (165°F).
Step 5
While the chicken and veggies are roasting, prepare the mustard dressing: Whisk together mustard, vinegar, maple syrup, salt, and cayenne in a small bowl until well combined.
Step 6
Drizzle the mustard dressing over the roasted veggies and chicken before serving.
