Sheet Pan Chicken with Brussels Sprouts and Sweet Potatoes
Sheet pan chicken with Brussels sprouts and sweet potatoes turns lean chicken, caramelized vegetables, garlic, paprika, and thyme into a colorful dinner with very little cleanup.
This is the kind of from scratch meal I make when I want something hearty, healthy, and simple. The sweet potatoes roast until creamy in the center. The Brussels sprouts get browned at the edges. The red onion softens and turns sweet. The chicken stays juicy when you cut it into even pieces and pull it from the oven as soon as it reaches a safe temperature.
Why You Will Love This Recipe
- Big flavor from pantry spices: Garlic, paprika, thyme, olive oil, salt, and pepper make the whole pan smell warm and savory.
- Balanced and filling: You get lean protein, fiber rich vegetables, and naturally sweet roasted potatoes in one meal.

Fabian’s Budget and Health Tip: Buy whole Brussels sprouts and trim them yourself. They often cost less than pre trimmed bags. If chicken breast is pricey, use boneless skinless chicken thighs and roast until they reach 165°F (74°C). They stay juicy and work well with the same seasonings.
Ingredients (Serves 4)
- 1 1/2 pounds chicken breast (680 g), cut into even bite sized pieces
- 1 pound Brussels sprouts (450 g), trimmed and halved
- 1 1/2 pounds sweet potatoes (680 g), peeled if desired and cut into 1 inch pieces (2.5 cm)
- 1 medium red onion (150 g), cut into wedges
- 3 tablespoons olive oil (45 ml), divided
- 3 garlic cloves (9 g), minced
- 2 teaspoons paprika (4 g)
- 1 teaspoon dried thyme (1 g)
- 1 teaspoon fine salt (6 g), plus more to taste
- 1/2 teaspoon black pepper (1 g)
Step-by-Step Instructions
1. Heat the Oven
Place a large rimmed sheet pan in the oven and heat to 425°F (220°C). A hot pan helps the vegetables start sizzling right away, which gives them better browning.
2. Season the Vegetables
Add the Brussels sprouts, sweet potatoes, and red onion to a large bowl. Toss with 2 tablespoons olive oil (30 ml), the garlic, half the paprika, half the thyme, half the salt, and a pinch of black pepper. Stir until the sweet potatoes look lightly glossy and the garlic clings to the vegetables.
3. Arrange the Pan
Carefully remove the hot sheet pan from the oven. Spread the vegetables in a single layer. Turn the Brussels sprouts cut side down when you can. That flat side will brown deeply and smell nutty as it roasts.
4. Season the Chicken
In the same bowl, toss the chicken pieces with the remaining 1 tablespoon olive oil (15 ml), remaining paprika, remaining thyme, remaining salt, and black pepper. Coat each piece well so every bite tastes savory and warm.
5. Roast the Chicken and Vegetables
Add the seasoned chicken to the sheet pan, spacing the pieces between the vegetables. Roast for 18 to 24 minutes, stirring once halfway through. The pan should smell like roasted garlic and sweet onion, and the vegetables should look browned at the edges.
6. Check for Doneness
Check the thickest chicken pieces with an instant read thermometer. The chicken is safe when it reaches 165°F (74°C). The sweet potatoes should pierce easily with a fork, and the Brussels sprouts should have crisp, dark golden edges.
7. Rest and Serve
Let the pan rest for 5 minutes before serving. This keeps the chicken juicy and lets the roasted flavors settle. Taste and add a small pinch of salt if the vegetables need more brightness.
Expert Troubleshooting and FAQs
Why did my vegetables steam instead of roast?
The pan was likely too crowded. Use the largest rimmed sheet pan you have and spread everything in one layer. If the vegetables sit in a pile, moisture gets trapped and the edges stay soft.
Can I use frozen Brussels sprouts?
Yes, but fresh sprouts roast better. If using frozen Brussels sprouts, do not thaw them first. Add them straight to the hot pan and expect a softer texture with less browning.
How do I keep chicken breast from drying out?
Cut the chicken into even pieces and check the temperature early. Pull it from the oven as soon as it reaches 165°F (74°C). Resting for 5 minutes also helps the juices stay inside.
Can I prep this ahead?
Yes. Cut the vegetables and chicken up to 24 hours ahead. Store them in separate covered containers in the refrigerator. Season right before roasting for the best texture.
What can I serve with this meal?
This sheet pan dinner is filling on its own. For a bigger meal, serve it with cooked rice, quinoa, warm pita, or a simple green salad with lemon juice.
