Roast Chicken with Rosemary Butter Recipe!

Before discovering how easy it was to make my own roast chicken, I used to get mine at Costco. You know the $4.99 roast chicken they’re famous for? The one that’s gigantic because the chicken is plumped up with hormones and sodium and who knows what else? While the roast chicken at Costco is delicious and so big it can feed us for days, it wasn’t the most healthy and I really didn’t know what was in it to make it taste so delicious.
So…I decided to make my own.
My Roast Chicken with Rosemary Butter recipe is made with organic whole chicken and just a few natural ingredients that you probably already have on hand: lemon, onion, fresh rosemary, Kerry Gold Irish butter, salt and pepper. You cannot get any simpler than that.
How To Make Roast Chicken with Rosemary Butter
- Preheat oven to 425 degrees.
- Take one of the rosemary sprigs and remove the stems by running your fingers along the sides. Roughly chop it up and mix it really well with the softened butter.
- Note: It’s very important that the butter is softened otherwise it won’t properly spread on the chicken.
- Rinse the chicken and pat dry with paper towels until very very dry.
- Place the chicken on a roasting pan or a sheet pan with wire rack (that’s what I used). Season the inside of the cavity liberally with salt and pepper and stuff with the quartered lemons and onions and rosemary sprigs. Continue to season the outside of the chicken with salt and pepper.
- Using a silicon basting brush, spread the butter and rosemary mixture all over the chicken. Don’t worry, it’s not too much. Trust me. Just keep spreading it all over. The butter is what will give the chicken its golden brown color and add to the flavor.
- Roast the chicken uncovered at 425 degrees for 1 1/2 hours until the juices run clear when you run your knife between the thigh and leg bone.
- Cover the chicken with foil and let it rest for 15 minutes before carving.
