Ingredients for baked chicken with potatoes and onions
The secret to crispy chicken and caramelized potatoes lies in these eleven simple, quality ingredients.
| Ingredient | Amount | Notes |
|---|---|---|
| Bone-In Chicken Thighs 🍗 | 1 ½ lb | Skin-on for crispy edges |
| Baby Potatoes 🥔 | 1 ½ lb | Halved, unpeeled for texture |
| Yellow Onions 🧅 | 2 whole | Sliced into 1/2-inch wedges |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For herb infusion and crisping |
| Garlic Cloves 🧄 | 4 cloves | Minced for herb blend |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Thyme 🌿 | 1 tbsp | Leaves only, chopped fine |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Ground Black Pepper 🌶️ | 1 tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | For extra flavor depth |
| Paprika 🌶️ | ½ tsp | Smoked for color and flavor |
The chicken thighs are the star, so choose bone-in, skin-on for maximum flavor and crispiness. Local butchers or Costco often have the best cuts—look for good marbling and vibrant color. Baby potatoes are perfect here, but if you only have large ones, cut them into even chunks. The yellow onions add sweetness as they caramelize, so avoid red onions which can turn bitter. Fresh herbs are non-negotiable—they infuse the chicken with aromatic depth that dried just can't match. I always grab extra rosemary because it holds up well during baking and adds that signature herbal note.
No bone-in thighs? Bone-in, skinless thighs work too, though you'll lose some crispiness. Substitute chicken breasts if needed, but increase baking time by 10-15 minutes and tent with foil to prevent drying. Fresh rosemary or thyme unavailable? Dried works at one-third the amount, but toast it first in a dry pan for 30 seconds to enhance flavor. The paprika adds beautiful color—smoked is best, but regular works in a pinch. For extra crispiness, sprinkle cornstarch or breadcrumbs on the chicken before baking. And if you're prepping ahead, the potatoes can be parboiled the night before to cut baking time.
This dish reheats beautifully—just pop it back in the oven at 375°F for 10-15 minutes. The chicken stays juicy and the potatoes crisp up again. Store leftovers in an airtight container for up to 4 days in the fridge. For meal prep, I portion the chicken separately from the potatoes—they reheat differently. The herb-infused oil keeps for 1 week in the fridge, perfect for drizzling on salads or roasted veggies. Freeze the chicken and potatoes separately for up to 3 months—thaw overnight in the fridge before reheating.

Step-by-step instructions for herb-infused baked chicken and vegetables
Here's how to achieve a golden crust on chicken while keeping potatoes tender and onions caramelized.
Prep Ingredients for Even Cooking
Preheat your oven to 425°F and position a rack in the lower third. Pat the 1.5 lb bone-in chicken thighs dry with paper towels—this ensures maximum crispiness. Trim any excess fat but leave the skin intact for flavor and texture.
Cut the 1.5 lb baby potatoes in half lengthwise (no need to peel) and slice the 2 whole yellow onions into ½-inch wedges. Toss the potatoes and onions in a large bowl with ½ cup extra-virgin olive oil, ½ tsp salt, and ¼ tsp black pepper. Spread on a baking sheet and let sit while you prepare the herb blend.
Create the Herb Oil for Maximum Flavor
In a small bowl, finely chop the 4 garlic cloves and mix with the ¼ cup fresh rosemary and 1 tbsp fresh thyme. Add the remaining 1 tsp salt, ½ tsp black pepper, ½ tsp garlic powder, and ½ tsp paprika. Rub this mixture all over the chicken thighs, pressing it into the skin and any crevices.
Place the seasoned chicken thighs on a separate baking sheet lined with parchment paper. The herb oil will infuse the chicken while it cooks, creating layers of flavor under that crispy crust. Let everything sit at room temperature for 10 minutes before baking—this ensures even cooking.
Layer and Bake for Crispy Top and Tender Centers
Arrange the chicken thighs on the baking sheet with potatoes and onions. Spread the potatoes and onions evenly around the chicken, leaving space for air circulation. Bake for 35 minutes at 425°F, then reduce heat to 375°F and continue baking for another 30-35 minutes.
You'll know it's done when the chicken skin is deep golden brown and crispy, the potatoes are fork-tender with slightly crisp edges, and the onions are caramelized. The internal temperature of the chicken should reach 165°F when measured in the thickest part. If the potatoes seem underdone, cover loosely with foil and bake 10 minutes more.
Rest and Serve for Maximum Juiciness
Transfer the chicken to a cutting board and tent loosely with foil. Let it rest for 10 minutes before carving—this allows the juices to redistribute, ensuring each bite stays moist. The potatoes and onions can be served immediately from the baking sheet.
For serving, arrange the crispy chicken thighs alongside the tender potatoes and caramelized onions. The contrast of textures—crispy skin, tender meat, fluffy potatoes, and sweet onions—makes this dish truly special. The herb-infused oil adds an aromatic depth that ties everything together perfectly.
Pro Tips For Making Baked Chicken With Potatoes And Onions
- Parboil Baby Potatoes First: I learned this the hard way—skipping the 8-10 minute boil leaves baby potatoes tough and undercooked by the time the chicken finishes. Drain them well afterward, or they’ll steam instead of crisp up in the oven. (Yes, even if you’re impatient like me.)
- Salt the Chicken Generously: Bone-in thighs need salt before they go in the oven—at least 15 minutes ahead if possible. I used to salt them right before baking, and the skin never got crispy. Season both sides aggressively, especially the bone side, where flavor clings.
- Slice Onions Thinly: Thick onion slices turn mushy while the chicken cooks. Aim for ⅛-inch slices—thin enough to caramelize but not so fine they disappear. A sharp knife and steady hand make this easier than it sounds.
- Rotate the Pan Mid-Bake: After 40 minutes, swap the top and bottom racks and rotate the pan 180 degrees. The chicken on the bottom rack gets overcooked, and the onions on top stay pale. This guarantees even browning and crispy edges without burning. (Your future self will thank you.)
Essential equipment for perfect results
Sheet Pan Essentials
You only need two sheet pans—one for the chicken and one for the potatoes and onions. I swear by half-sheet pans (18x13 inches) because they fit perfectly in most home ovens and allow even heat distribution.
Line them with parchment paper for easy cleanup and prevent sticking—no more scrubbing baked-on food. 🔥
For the chicken pan, I use heavy-duty aluminum foil to create a tent during resting. This keeps the meat juicy while allowing steam to escape. Avoid non-stick pans here—they can't handle the high heat needed for crispy skin.
If you're short on space, use one large sheet pan but bake the chicken first for 20 minutes, then add potatoes and onions for the remaining time.
Oven Thermometer
Your oven's temperature gauge is probably wrong—mine was off by 25°F before I bought a Thermoworks Oven Thermometer. For this recipe, 425°F is critical for crispy chicken and caramelized onions.
Place the thermometer near the oven rack where your pans will sit. If your oven runs hot, reduce the temperature by 10-15°F to avoid overcooking.
Tongs and Meat Thermometer
Tongs are your best friend for arranging the chicken and veggies without tearing the skin. I use OXO Good Grips because they're sturdy and comfortable. A meat thermometer is non-negotiable—insert it into the thickest part of the chicken thigh to check for 165°F. My go-to is the Thermoworks Smoke, which also tracks the oven temperature simultaneously.
Parchment Paper
Parchment paper isn't just for cleanup—it creates a non-stick barrier that helps develop Maillard reaction on the chicken skin. Use 100% pure parchment (no silicone blends) for best results. Cut it to fit your pans with 1-inch overhang on the sides for easy transfer.
If you're baking on a glass pan, parchment prevents hot spots that can burn the bottom of your potatoes.
Herb Scissors
Chopping fresh rosemary and thyme with a knife is messy, but herb scissors make prep effortless. I keep a pair of Westmark Herb Scissors in my kitchen for this exact purpose—they're sharp, easy to clean, and last forever.
For the garlic, a garlic press saves time and ensures even mincing. These small tools make all the difference in flavor infusion.
Optional Upgrades
Want to take it to the next level? A wire cooling rack lets air circulate under the chicken while resting, keeping it crispy. For extra crispiness, sprinkle 1 tbsp cornstarch on the chicken skin before baking.
And if you're feeling fancy, a silicon baking mat on the sheet pan adds texture to the potatoes. These aren't essential, but they elevate the dish from good to restaurant-quality. 💫

Frequently asked questions
Can I use chicken breasts instead of thighs?
Yes, but with adjustments! Chicken breasts cook faster and dry out more easily. Use bone-in, skin-on breasts and increase baking time by 10-15 minutes. Tent with foil after 25 minutes to prevent overcooking. For extra moisture, brine the breasts for 30 minutes before baking—this keeps them juicy despite the shorter cooking time.
Why are my potatoes still hard after baking?
Hard potatoes usually mean they weren't cut small enough or didn't have enough time. Halve baby potatoes lengthwise (or quarter larger ones) for even cooking. If they're still hard after 60 minutes, cover loosely with foil and bake 10-15 minutes more. Parboiling the potatoes for 5 minutes before baking also helps—just drain and pat dry first.
How can I make this dish ahead of time?
Prep everything the night before! Parboil the potatoes for 5 minutes, then store them in cold water in the fridge. Season the chicken and let it rest at room temperature. When ready to bake, pat everything dry and proceed with the recipe. For leftovers, store components separately—the chicken reheats best in the oven at 375°F for 10 minutes, while potatoes can go in the microwave with a damp paper towel.
Can I add other vegetables to this dish?
Carrots, bell peppers, and zucchini work beautifully—just slice them into ½-inch pieces and add them with the potatoes. For heartier veggies like Brussels sprouts, roast them separately first. Avoid leafy greens—they'll wilt in the high heat. If adding extra veggies, increase baking time by 5-10 minutes to ensure everything cooks through.
What's the best way to reheat leftovers?
For best results, reheat components separately. Place chicken on a baking sheet at 375°F for 10-15 minutes until heated through. Microwave potatoes for 1-2 minutes with a damp paper towel to restore crispiness. Never reheat chicken in the microwave—it makes the skin rubbery. If you must use the microwave, cover with a damp towel and heat in 30-second bursts until warm.
