Easy Garlic Dijon Chicken baked with crispy skin and tender Brussels sprouts. This healthy, flavorful one-pan meal features a zesty garlic and lemon marinade perfect for quick weeknight dinners or meal prep.

Ingredients
For the Chicken Marinade:
- 2 tablespoons olive oil
- 2 garlic cloves, pressed or minced
- 2 tablespoons fresh parsley, finely chopped (plus extra for garnish)
- 2 tablespoons lemon juice (about 1 lemon)
- 1 tablespoon Dijon mustard
- ½ tablespoon sea salt
- ¼ teaspoon black pepper
For the Chicken and Brussels Sprouts:
- 8 boneless, skin-on chicken thighs
- 1½ pounds Brussels sprouts, trimmed and halved
- ½ teaspoon sea salt
- ⅛ teaspoon black pepper
- 2 teaspoons olive oil
Instructions
- Prepare the marinade: In a small bowl, whisk together olive oil, garlic, parsley, lemon juice, Dijon mustard, sea salt, and black pepper.
- Marinate the chicken: Place chicken thighs in a large bowl or resealable bag. Pour marinade over the chicken and toss to coat evenly. Refrigerate for at least 6 hours, preferably overnight, for best flavor.
- Prepare the Brussels sprouts: Trim and halve the Brussels sprouts. Arrange them on a parchment- or silicone-lined baking sheet. Sprinkle with sea salt, black pepper, and olive oil. Toss to combine and spread the sprouts evenly along the edges of the pan in a single layer.
- Arrange the chicken: Place the marinated chicken thighs skin-side up in the center of the baking sheet, leaving about ½ inch space between each piece.
- Bake: Preheat the oven to 400°F (200°C). Bake the chicken and Brussels sprouts uncovered for 25 minutes (30 minutes if using bone-in thighs).
- Optional crispy skin: For extra crispy skin, broil on high for 2–4 minutes or until the chicken skin turns golden brown and crisp.
- Serve: Garnish with extra fresh parsley before serving.
