Pat the chicken completely dry with paper towels; this is key for crispy skin. If you want a more polished look, tie the legs together with kitchen twine and tuck the wings underneath.
1 whole chicken
In a small bowl, mix the salt, pepper, garlic powder, onion powder, smoked paprika, and thyme.
1 1/2 teaspoons salt, 1 teaspoon black pepper, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon smoked paprika, 1 teaspoon dried thyme
Rub the chicken all over with olive oil (or melted butter), then coat it evenly with the seasoning mixture. Don’t forget under the wings and around the legs.
2 tablespoons olive oil
Place the lemon halves, garlic, and a few onion pieces inside the cavity. This adds moisture and a subtle, aromatic flavor from the inside out.
1 lemon, 1 head of garlic, 1 small onion
Add the carrots, celery, and remaining onion to the bottom of your Dutch oven. This creates a natural roasting rack and infuses the drippings with flavor. Place the chicken breast-side up on top of the veggies.
3-4 carrots, 2-3 celery stalks
Cover with the lid and roast at 375 °F (190 °C) for about 60 minutes. This step locks in moisture and gently cooks the chicken.
Remove the lid and continue roasting for another 30-45 minutes, or until the skin is golden and crispy and the internal temperature reaches 165 °F (74 °C) in the thickest part of the thigh. If you want extra crispiness, you can broil for 2-3 minutes at the end - just keep a close eye on it.
Let the chicken rest for 10-15 minutes before slicing. This keeps all those juices right where you want them.
Store leftover chicken in an airtight container in the refrigerator for up to 4 days. To reheat, place the chicken in a baking dish with a splash of broth and warm at 300 °F (150 °C) until heated through.
