🍗 Best Cuts of Chicken to Use
When it comes to oven-roasting, not all cuts are equal. Here are the best choices:
- Bone-in, skin-on chicken thighs – Juicy, flavorful, and almost impossible to overcook
- Drumsticks – Economical and loved by kids
- Split chicken breasts – Leaner but stay moist when bone-in and skin-on
- Whole chicken cut into pieces – Great for variety on a single tray
🔪 Tip: Avoid boneless, skinless cuts unless you’re adjusting cooking times significantly—they dry out quickly during roasting.
🥔 Best Potatoes for Roasting
Not all potatoes hold up to high-heat roasting. The team at Serious Eats suggests using:
- Yukon Gold – Creamy, slightly sweet, and crisp up nicely
- Red potatoes – Waxy, hold shape, perfect texture
- Fingerling potatoes – Elegant and tender
🧂 Avoid: Russet potatoes—they’re too starchy and tend to fall apart.
Cut your potatoes into even, 1½-inch pieces for even cooking.

🔪 Prep Instructions
- Preheat oven to 425°F (220°C).
- Dry the chicken thoroughly with paper towels. This helps the skin crisp up.
- Toss potatoes and onions in a bowl with olive oil, salt, pepper, and half of your herbs.
- Arrange vegetables on a large rimmed baking sheet or roasting pan.
- Nestle chicken pieces on top. Drizzle everything with a little more oil, squeeze the lemon over the pan, and tuck the lemon halves in.
🔥 How to Roast – Step-by-Step
Making oven-roasted chicken with potatoes and onions doesn’t require special tools or complicated techniques — just one pan and a hot oven. Follow these simple steps to ensure crispy chicken skin, golden roasted potatoes, and caramelized onions that melt in your mouth.
🍳 Step 1: Preheat the Oven
Preheat your oven to 425°F (220°C). This high temperature ensures:
- A golden, crispy skin
- Deep caramelization of onions
- Potatoes that roast instead of steam
📝 Tip: Avoid lower temps unless you’re cooking a whole chicken — this recipe benefits from heat.
🧂 Step 2: Season and Assemble the Pan
Prepare your ingredients before placing them in the pan:
- Pat the chicken dry with paper towels — this helps the skin crisp.
- Toss the potatoes and onions in a bowl with olive oil, salt, pepper, herbs, and garlic.
- Layer vegetables evenly on a rimmed baking sheet or roasting pan.
- Place chicken skin-side up on top of the vegetables, spacing pieces evenly.
- Squeeze fresh lemon juice over the entire tray, and tuck the lemon halves around the chicken.
🧄 Want more flavor? Add extra whole garlic cloves or sprigs of rosemary between the chicken and vegetables.
⏱️ Step 3: Roast in the Oven
- Place the pan on the center rack of your preheated oven.
- Roast uncovered for 35–45 minutes, depending on the size of your chicken pieces.
- Flip the potatoes and onions gently halfway through to ensure even browning.
- Use a meat thermometer to check for doneness:
- Internal temperature of chicken should be 165°F (74°C) at the thickest part
- Juices should run clear
🔥 Optional: Broil during the last 2–3 minutes to crisp up the chicken skin even more.
🧍 Step 4: Let It Rest
Remove the pan from the oven and allow the chicken to rest for 5 minutes. This:
- Locks in juices
- Prevents the meat from drying out
- Gives the vegetables time to settle and soak up residual juices
🪄 Optional Finishing Touches
For next-level flavor and presentation:
- Drizzle with pan juices or a splash of broth to create a light gravy
- Top with chopped fresh herbs (parsley, chives, or thyme)
- Serve straight from the pan for rustic charm
💡 Bonus: Two-Sheet Pan Method
If you’re doubling the recipe or want extra-crispy potatoes:
- Roast chicken and vegetables on separate pans
- Place the chicken on a wire rack set over a pan to allow airflow
- This prevents crowding and keeps everything crisp
Now that you know how to roast like a pro, your one-pan roasted chicken dinner will come out perfect every time — crispy on top, juicy in the middle, and golden on the bottom.
🧂 Tips for the Perfect Roast
- Pat chicken dry before roasting to help crisp the skin.
- Don’t crowd the pan — use two sheets if needed to avoid steaming.
- Roast high and fast — 425°F delivers golden skin and fluffy potatoes.
- Use a rack or elevate the chicken slightly if you prefer it crisp on all sides.
