Garlic Butter Roasted Chicken and Potatoes

If you’ve ever wondered how restaurants get their roast chicken so juicy and full of flavor, the secret is simple — it’s all in the brine! This brined Roasted Chicken and Potatoes is one of those meals that makes you slow down and savor every bite.

The kids voted this was the best chicken and potatoes I’ve ever made and it was one pan and so dang easy.

The overnight brine infuses the meat with moisture and a subtle, herby flavor, while the garlic butter under the skin keeps every bite tender and golden. Add in roasted Yukon Gold potatoes that crisp up in the chicken drippings, and you’ve got a family dinner that is pure comfort food — with hardly any effort.

Why Brining Makes the Juiciest Chicken

The short answer is science! First, the salt in the brine breaks down the tight protein strands in chicken (or any poultry) which makes the structure more open to holding liquid molecules so it can retain more moisture.

When the chicken is submerged in the brine, the chicken soaks up the brine making it more juicy and more flavorful. The additional flavor in the brine like the lemon, fresh herbs and garlic all soak into the chicken so it’s flavored from the inside out!

Ingredients You’ll Need

For the Brine

• Water: The base that helps distribute the salt and flavors evenly.
• Kosher Salt: Draws moisture in and out of the chicken, resulting in juicy, seasoned meat.
• Honey: Adds a subtle sweetness and helps with browning during roasting.
• Peppercorns: Infuse mild spice and depth into the brine.
• Lemons: Brighten the flavor and help tenderize the meat.
• Bay Leaves: Add an earthy, aromatic note.
• Parsley & Thyme: Fresh herbs that lend light, savory flavor.
• Garlic: Deepens the flavor and complements the herbs beautifully.

For the Chicken

• Whole Chicken: The star of the recipe — roasting the entire bird keeps it juicy, flavorful, and beautifully golden while naturally basting the potatoes as it roasts.
• Kosher Salt: Enhances flavor, draws out moisture for crisp skin, and seasons both the chicken and potatoes evenly.
• Butter: Adds richness and helps the skin turn golden and crispy while keeping the meat tender and moist.
• Garlic: Brings depth and savory aroma to the butter mixture and infuses flavor into the chicken and potatoes.
• Fresh Thyme: Adds bright, earthy notes that complement the chicken’s richness and balance the buttery flavor.
• Lemon: Infuses the meat with a fresh citrus aroma, helps tenderize the chicken, and adds brightness to the pan juices.
• Red Onion: Adds sweetness and moisture to the roasting pan, enhancing flavor and preventing dryness.
• Yukon Gold Potatoes: Perfectly soak up the drippings from the chicken — soft and buttery inside with crisp, golden edges.
• Olive Oil: Prevents sticking, promotes browning, and adds a layer of richness to both the chicken and potatoes.

1. Dissolve: Mix the water, salt and honey in a large pot over medium heat and stir until the salt is dissolved. Remove from the heat and let the water cool.
2. Brine: Add the remaining ingredients to the pot, then add the chicken to the brine solution and let it brine in the fridge overnight.
3. Prep the Chicken: Remove the chicken from the brine and pat it dry. Sprinkle with salt and place in the fridge uncovered for a day.
4. Preheat: Place a cast iron skillet in the over and heat the oven to 425℉.
5. Make the Garlic Butter: Add the butter, garlic, thyme and lemon zest to a small bowl and combine thoroughly.
6. Rub: Lift the chicken skin and rub the garlic butter all over the chicken under the skin and on top of the skin.
7. Assemble the Dish: Pull the skillet from the oven and drizzle it with olive oil. Place the chicken in the pan (breast side up) and place the potatoes around it. Drizzle everything with olive oil and sprinkle the potatoes with kosher salt.
8. Roast: Place the pan back in the oven and roast for 1 hour. Rotate the pan halfway through the cook time.
   • NOTE: You want an internal temperature of 165 degrees F in the thickest part of the thigh.

Storing and Reheating Leftovers

Leftover roasted chicken should be stored in an airtight container in the refrigerator.
It will keep for 3-4 days in the refrigerator.

To reheat roasted chicken, place it in an oven safe dish and reheat in a 350 degree oven for about 25 minutes. You can also reheat in a microwave for 2-5 minutes. 

Leftovers can also be frozen. Place the cooled chicken in ziploc freezer bags and press out as much air as possible before sealing the bag. It will keep in the freezer for up to 4 months.
