Spatchcocked Sunday Roast Chicken with Umami Herb Butter
Growing up in Atlanta, Sunday supper was non-negotiable, and a whole roasted bird was always the star. But I'll let you in on a secret: my grandmother's chicken sometimes got a little dry in the breast before the dark meat was done. In Charleston, I learned the magic of spatchcocking for a perfectly even, blistered-skin roast, and I started slipping a fish-sauce-spiked herb butter right under the skin to amplify the savory notes.

- 1.5 tsp Black pepper(Freshly ground, divided use)

Instructions
- 1
Preheat your oven to 425 degrees. In a large bowl, toss 1.5 lbs baby gold potatoes and 2 medium Vidalia onions with 2 tbsp olive oil, 1 tsp kosher salt, and 0.5 tsp black pepper. Spread them out evenly on a heavy-duty rimmed baking sheet. These are going to act as our roasting rack and catch all the incredible drippings.
5 min
Tip: Make sure the potatoes are cut-side down against the pan so they get beautifully caramelized.

Now, let's spatchcock the 1 whole chicken. Place the bird breast-side down on a stable cutting board. Using heavy-duty poultry shears, cut along both sides of the backbone from tail to neck. Remove the backbone (stash it in the freezer for Sunday stock!). Flip the bird over, splay it open, and press down hard with the heel of your hand right on the center of the breastbone until you hear a satisfying crack and the chicken lays completely flat. Pat the entire bird completely dry with paper towels.

Tip: Drying the skin thoroughly is the absolute non-negotiable secret to crispy, golden skin.

In a small bowl, mash together the 4 tbsp unsalted butter, 1 tbsp fish sauce, 1 tbsp fresh thyme leaves, 1 tbsp fresh rosemary, 3 cloves minced garlic, and 1 tsp lemon zest. It might look like it's breaking or separating at first, but just keep mashing with a fork until it comes together into a beautiful compound butter.
5 min
Tip: If your butter is too cold, give it 5 seconds in the microwave. It needs to be very soft to mix properly with the fish sauce.
- 4
Gently slide your fingers under the skin of the chicken at the neck and breast, loosening it all the way down to the thighs. Be careful not to tear it. Push the butter mixture under the skin, massaging it from the outside to distribute it evenly over the meat. Rub the outside of the skin with the remaining 1 tbsp olive oil, then season generously from high up with the remaining 1 tbsp kosher salt and 1 tsp black pepper.
5 min
Tip: Seasoning from a height ensures an even coating rather than clumps of salt.
- 5
Lay the prepared chicken completely flat right on top of the potatoes and onions on the baking sheet. Tuck the 1 whole lemon (sliced) in and around the chicken and vegetables.
2 min
Tip: Make sure the legs are turned outward so they get maximum heat exposure.
- 6
Transfer the sheet pan to the oven and roast until the skin is deeply browned, crispy, and an instant-read thermometer inserted into the thickest part of the thigh registers 165 degrees. The vegetables underneath will be meltingly tender and rich with the savory pan drippings.
45 min
Tip: Rotate the pan halfway through cooking if your oven has hot spots.
- 7
Remove the pan from the oven. Transfer the chicken to a carving board and let it rest undisturbed. This allows the juices to redistribute back into the meat. While the chicken rests, give the potatoes and onions a gentle toss in the pan fat. Carve the chicken and serve it right alongside the dripping-soaked vegetables.
10 min
Tip: Never skip the rest! If you cut in too early, all that hard work and flavor will literally run away across your cutting board.
Chef's Notes
Don't let the fish sauce scare you away from this recipe! It does not make the chicken taste like seafood. When combined with butter, garlic, and roasting temperatures, it transforms into pure, concentrated umami. It's my nod to the deep flavor profiles I learned working the line in Charleston, seamlessly melded with my grandmother's Atlanta table.
