Best Rosemary Chicken and Veggies – One-Pan Dinner

Rosemary Garlic Roasted Chicken and Vegetables is a complete one-pan meal that delivers tender, juicy chicken and caramelized vegetables with minimal effort. The key is high-heat roasting, which creates a crispy skin and concentrates the natural sugars in the vegetables.

This recipe is built for busy weeknights: you'll spend 15 minutes prepping, then let the oven do the work. The combination of fresh rosemary and garlic infuses the dish with aromatic flavor, while the vegetables—potatoes, carrots, and red onion—roast to golden perfection.

Whether you're feeding a family or meal-prepping for the week, this dish scales easily and tastes even better the next day. Follow the precise temperatures and times below to achieve consistent results every time.

About the Ingredients

4 bone-in, skin-on chicken thighs (about 2 lbs / 900g)

Bone-in thighs stay moist during roasting. Substitute with bone-in drumsticks or a whole cut-up chicken; adjust cooking time accordingly.

1 lb (450g) baby potatoes, halved

Use Yukon Gold or red potatoes; they hold their shape well. Substitute with quartered regular potatoes if needed.

3 large carrots, peeled and cut into 2-inch chunks

Carrots add sweetness and color. Swap with parsnips or turnips for a different root vegetable mix.

1 large red onion, cut into 8 wedges

Red onion caramelizes beautifully. Use yellow or white onion if that's what you have.

3 tablespoons olive oil, divided

Extra virgin olive oil works best; substitute with avocado oil for a higher smoke point.

2 tablespoons fresh rosemary, chopped

Fresh rosemary is essential for flavor; if using dried, reduce to 1 tablespoon and add to the marinade.

4 cloves garlic, minced

Fresh garlic provides pungent flavor; use 1 teaspoon garlic powder if you're out of fresh.

1 teaspoon salt

Kosher salt or sea salt works; adjust to taste.

1/2 teaspoon black pepper

Freshly ground pepper gives the best flavor; pre-ground is fine.

1 lemon, zested and juiced

Lemon brightens the dish; use bottled lemon juice if needed, but fresh is better.

Tips & Tricks

• Pat the chicken dry with paper towels before seasoning to ensure crispy skin.
• Arrange the vegetables in a single layer on the pan—crowding causes steaming instead of roasting.
• Use a meat thermometer to check the chicken's internal temperature; it should reach 165°F (74°C) in the thickest part.

Step-by-Step Instructions

1. Preheat Oven

Preheat your oven to 425°F (220°C). Position a rack in the middle of the oven.

2. Prepare Marinade

In a small bowl, combine 2 tablespoons olive oil, chopped rosemary, minced garlic, salt, pepper, lemon zest, and lemon juice. Whisk to blend.

3. Season Chicken

Pat the chicken thighs dry with paper towels. Brush the marinade over the chicken, ensuring even coverage. Set aside.

4. Toss Vegetables

In a large bowl, combine halved potatoes, carrot chunks, and onion wedges. Drizzle with the remaining 1 tablespoon olive oil, sprinkle with a pinch of salt and pepper, and toss to coat.

5. Arrange on Pan

Spread the vegetables in a single layer on a large rimmed baking sheet. Place the chicken thighs skin-side up on top of the vegetables.

6. Roast

Roast for 35-40 minutes, until the chicken skin is golden brown and crispy, the vegetables are tender, and the chicken reaches an internal temperature of 165°F (74°C). If the chicken browns too quickly, tent with foil.

7. Rest and Serve

Remove from the oven and let rest for 5 minutes. Serve hot, spooning pan juices over the chicken and vegetables.

Delicious Variations

Mediterranean Twist

Add cherry tomatoes and kalamata olives during the last 10 minutes of roasting.

Spicy Version

Sprinkle 1 teaspoon smoked paprika and 1/2 teaspoon cayenne pepper into the marinade.

Herb Swap

Replace rosemary with fresh thyme or oregano for a different flavor profile.
