This cast iron roast chicken recipe is the best way to cook a whole chicken in the oven. Tender and juicy and roasted to perfection, this easy one pan whole roasted chicken recipe is perfect for Sunday dinner!
I love cooking food in cast iron. It's great for searing or slow cooking and it is cookware that will last forever. It's probably the only type of pan that gets better the more you use it. Cast Iron absorbs all the flavor and seasoning from the dishes you cook in it, which then in turn makes your next dish that much better.

🍗 Ingredient notes
- Whole Chicken - A broiler, roaster, or fryer chicken will work best for this recipe. They will vary in size but aim for a chicken between 4-6 pounds.
- Sliced Onions - These will provide a bed for the chicken to rest on and will not only flavor the chicken but caramelize during cooking for some super tasty drippings.
- Whole Lemon, Fresh Thyme, and Sage - These are the "aromatics" that will go inside the cavity of the bird that will also help flavor it.
- Olive Oil, Salt & Pepper - These will be rubbed on the outside of the chicken to help brown the skin, provide flavor and also help retain moisture.
📋 Substitutions and variations
- Whole meal - add potatoes and vegetables to the pan around the chicken to make it a complete dinner!
- Italian style - rub 1 Tablespoon of Italian season on the bird after you add the olive oil and salt and pepper for an Italian style roasted chicken
🔪 Step by step instructions
Slice your onion and place it in your cast iron skillet. Make sure you pick a skillet that is bigger than your chicken. Anywhere from a 12" - 15" skillet should work.
Remove the gizzards from the chicken and pat it dry. Place the chicken in your skillet on the sliced onions. Stuff the inside of the chicken with a lemon that has been cut in half and a few sprigs of fresh thyme and sage.
Using cooking twine, tie the two legs together and then tuck the wings inside or under the breast so they don't burn.
Rub the chicken with olive oil and sprinkle it with salt and pepper.
Roast the chicken in a 375° oven for 1 ½ - 2 hours until the chicken registers 165° with a kitchen thermometer in the thickest part of the breast and thigh. Let chicken rest for 10 minutes before carving and serving with the pan drippings.

⏲️ Cooking time
As a rule of thumb, you should roast a chicken for about 20 minutes per pound.
Example: 6-pound chicken = 2 hours cooking time
This time can vary depending on your oven and the exact size of the bird. I recommend checking the temperature with a kitchen thermometer about 20 minutes before it should be "done" to see where it's at. This will give you an idea of how much longer it needs.
⭐ Top tip
Always cook any chicken dish to 165° before removing it from the oven. Using a kitchen thermometer, check the temperature of the bird in the thickest part of the thigh and breast.
