Ingredients

Servings:

1 whole chicken (4–5 lb / 1.8–2.3 kg, preferably room temperature)
1 tbsp (18g) kosher salt (half as much if using fine table salt)
1/2 tsp (1g) black pepper, or more to taste
2 tsp (6g) garlic powder
1 tsp (3g) onion powder
5 celery stalks, cut in half lengthwise (3 pieces for cavity, 2 for baking sheet base)

Instructions

1
Preheat & Prep: Preheat the oven to 350°F. If time allows, let the chicken sit at room temperature for 30-45 minutes for even cooking. Pat the skin dry with paper towels.
2
Season the Chicken: Mix garlic powder, onion powder, salt, and pepper. Season the chicken evenly, making sure to rub at least 1.5 tsp of the mix inside the cavity.
3
Aromatics & Setup: Place halved celery stalks on a foil-lined baking sheet. Stuff 3 pieces into the chicken cavity to act as aromatics and help the breast cook evenly. Lay the chicken breast-side down on the celery.
4
Roast & Flip: Roast for 30 minutes, then flip the chicken using wooden spoons. Optionally, brush the skin with olive oil for extra browning. Continue roasting breast-side up for another 40-50 minutes until the internal temp reaches 175°F for the thighs and 165°F for the breast. I find the total roasting time is quite long—usually around 1 hour and 20 or 1 hour and 30 minutes. Consider broiling for a few minutes at the end, watching closely not to burn.
5
Rest & Serve: Let the chicken rest for 10 minutes, then carve and serve! Enjoy your perfectly roasted, juicy chicken!

FAQ

How long should you let chicken come to room temperature before roasting?+

You should let your chicken sit at room temperature for 30-45 minutes before roasting to ensure even cooking throughout the bird. This helps the chicken cook more consistently, resulting in juicy meat instead of overcooked edges and an undercooked center.

Can you make this roast chicken ahead and reheat it?+

Yes, you can roast the chicken up to 3 days ahead and store it in the refrigerator, then gently reheat it covered with foil at 350°F for about 15-20 minutes. For best results, let it come to room temperature first to avoid drying out the meat.

What can you substitute for celery if you don't have it?+

You can replace the celery with other aromatic vegetables like carrot chunks, onion halves, or fresh herbs like thyme and rosemary bundles stuffed in the cavity and on the baking sheet. These alternatives will still add flavor and help create a moist roasting environment.

Why is it important to pat the chicken skin dry before roasting?+

Patting the skin dry with paper towels removes surface moisture, which allows the skin to brown and crisp up instead of steaming during roasting. This is key to getting that golden, crackling exterior while keeping the meat juicy inside.
