Ingredients for Sheet Pan Chicken and Brussels Sprouts

- ¼ cup olive oil (extra virgin recommended)
- 2 tablespoons Dijon mustard (substitute with whole-grain mustard if preferred)
- 1 tablespoon fresh lemon juice (about half a lemon)
- 1 tablespoon fresh thyme (or 1 teaspoon dried thyme)
- ½ teaspoon salt (adjust to taste)
- ½ teaspoon ground black pepper
- 3 cloves minced garlic (or 1 teaspoon garlic powder as a substitute)
- 8 chicken thighs (bone-in, skin-on, about 2.5-3 lbs)
- 1 lb Brussels sprouts (trimmed and halved)
- 1 small red onion (sliced)
- ½ lemon (thinly sliced, for added flavor)
Step-by-Step Instructions
- Preheat the oven to 425°F (220°C).
- Prepare the marinade: In a small bowl, whisk together olive oil, Dijon mustard, lemon juice, thyme, salt, black pepper, and minced garlic until well combined.
- Marinate the chicken: Place the chicken thighs in a large bowl. Pour ⅔ of the marinade over the chicken and toss until fully coated. Cover and refrigerate for at least 20 minutes (up to 6 hours for deeper flavor).
- Toss the vegetables: In a medium bowl, combine Brussels sprouts, sliced red onion, and lemon slices. Add the remaining marinade and toss until evenly coated.
- Arrange on the sheet pan: Spread the vegetables in a single layer on a large baking sheet. Nestle the marinated chicken thighs among the vegetables.
- Bake: Place the sheet pan in the preheated oven and bake for 30-40 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
- Optional crispy skin: For extra crispy chicken skin, switch the oven to broil and cook for an additional 3-5 minutes, watching closely to avoid burning.
- Serve: Remove from the oven, let rest for 5 minutes, and serve warm. Enjoy!
Perfect Pairings: Serving Suggestions
This Sheet Pan Chicken and Brussel Sprouts dish is a complete meal on its own, but you can elevate it with a few simple sides. Serve with fluffy quinoa or garlic mashed potatoes for added comfort. A light arugula salad with lemon vinaigrette adds a fresh, tangy contrast to the hearty flavors.
Keep It Fresh: Storage and Reheating Tips
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the chicken and vegetables on a baking sheet and warm in a preheated 350°F oven for 10-15 minutes. This helps maintain crispiness better than microwaving.
Switch It Up: Recipe Variations
Feel free to customize this dish! Swap Brussel sprouts for broccoli or cauliflower, or try chicken breasts instead of thighs for a leaner option. For a Mediterranean twist, add kalamata olives and artichoke hearts to the vegetable mix.
Quick Tips for Maximum Flavor
Don’t skip the marinade—even 20 minutes makes a difference! To save time, prep the veggies while the chicken marinates. For extra crispiness, pat the chicken thighs dry before adding the marinade and ensure the vegetables are in a single layer on the sheet pan.
Essential Equipment Guide
A large, rimmed baking sheet is key for this recipe. Use parchment paper or a silicone baking mat for easier cleanup. A meat thermometer ensures your chicken reaches the safe internal temperature of 165°F without overcooking.
