Ingredients

For the Chicken & Vegetables

• 4 boneless, skinless chicken thighs or breasts
• 500 g baby potatoes, halved
• 300 g fresh green beans, trimmed
• 2 tbsp olive oil
• 1 tsp garlic powder
• 1 tsp paprika
• 1 tsp dried Italian seasoning
• 1/2 tsp dried thyme
• 1/2 tsp salt
• 1/4 tsp black pepper

For the Lemon Garlic Sauce

• 3 tbsp olive oil
• 2 tbsp fresh lemon juice
• 3 garlic cloves, minced
• 1 tsp Dijon mustard
• 1 tsp honey
• 1/2 tsp dried oregano
• Pinch of salt
• Freshly cracked black pepper

For Finishing

• 2 tbsp fresh parsley, chopped
• Lemon wedges
• Fresh thyme, optional
• Extra Parmesan cheese, optional

How to Make It

1. Prepare the Oven

Preheat the oven to 425°F (220°C). Lightly grease a large baking dish or sheet pan.

2. Season the Potatoes

Place the halved baby potatoes in a large bowl. Add 1 tbsp olive oil, garlic powder, paprika, Italian seasoning, salt, and black pepper. Toss thoroughly until the potatoes are evenly coated.

3. Roast the Potatoes First

Spread the potatoes cut-side down on the prepared baking sheet. Roast for 15 minutes. Starting the potatoes first gives them a head start so they become golden and tender while the chicken cooks.

4. Season the Chicken

Pat the chicken dry with paper towels. Rub with the remaining olive oil and season with thyme, salt, black pepper, and a little paprika.

5. Add the Chicken

Remove the baking sheet from the oven and carefully arrange the chicken pieces among the partially roasted potatoes.

6. Make the Lemon Garlic Sauce

In a small bowl, whisk together the olive oil, lemon juice, minced garlic, Dijon mustard, honey, oregano, salt, and freshly cracked black pepper until well combined.

7. Add the Green Beans

Toss the green beans with a little of the lemon garlic sauce, then arrange them around the chicken and potatoes.

8. Roast Everything

Return the pan to the oven and roast for 20–25 minutes, depending on the thickness of the chicken. The chicken should be cooked through and reach an internal temperature of 165°F (74°C), while the potatoes should be golden and tender.

9. Add More Sauce

Drizzle the remaining lemon garlic sauce over the hot chicken and vegetables. Let the sauce run over the potatoes and green beans for maximum flavour.

10. Garnish & Serve

Finish with fresh parsley, thyme, freshly cracked black pepper, and lemon wedges. Add a little Parmesan if desired and serve straight from the pan.

Why This Recipe Works

This one-pan chicken dinner keeps things simple while still delivering plenty of flavour. The potatoes roast until golden and savoury, the chicken stays juicy under the bright lemon garlic seasoning, and the green beans add freshness and colour.

The lemon, Dijon, garlic, and honey sauce is the finishing touch that ties everything together. It’s tangy, savoury, slightly sweet, and especially good spooned over those crispy potatoes.

Tips for the Best One-Pan Chicken

• Start the potatoes first: They need more cooking time than the chicken and green beans.
• Don’t overcrowd the pan: Leave some space around the ingredients so they roast rather than steam.
• Use a meat thermometer: Check the thickest part of the chicken and make sure it reaches 165°F (74°C).
• Add the sauce at the end: This keeps the lemon garlic flavour bright and fresh.
• Use chicken thighs for extra juiciness: Chicken breasts also work well, but thighs are more forgiving if they cook slightly longer.

Serving Suggestions

This roasted chicken dinner is satisfying enough to serve on its own, but you can easily add a simple side salad, crusty bread, or a spoonful of Greek yogurt with herbs.

For an extra Mediterranean-style finish, serve with additional lemon wedges, fresh parsley, and a light drizzle of extra-virgin olive oil.

Frequently Asked Questions

Can I use chicken thighs instead of chicken breasts?

Yes. Both boneless, skinless chicken thighs and breasts work well in this recipe. Chicken thighs tend to stay especially juicy and flavorful during roasting.

Can I use frozen green beans?

Fresh green beans are best for texture, but frozen green beans can also be used. Add them according to their package directions and avoid overcooking them.

Can I prepare this meal ahead of time?

You can season the chicken and potatoes several hours ahead and refrigerate them until you’re ready to cook. For the best texture, prepare the green beans and lemon garlic sauce shortly before roasting.

How do I know when the chicken is done?

The safest way is to use an instant-read thermometer. The thickest part of the chicken should reach 165°F (74°C).

Can I add other vegetables?

Yes. Bell peppers, zucchini, broccoli, or cherry tomatoes can be added. Keep in mind that different vegetables have different cooking times, so add delicate vegetables later if necessary.
