Cast-Iron Spatchcocked Chicken with Schmaltz Biscuit Croutons and Charred Mustard Greens
Growing up in Atlanta, Sunday supper at my grandmother's house was sacred. She could make a whole chicken stretch and sing, and nothing in her kitchen ever went to waste—especially yesterday's biscuits. That memory sparked this dish. I wanted to capture that deep, soulful comfort but elevate it with modern technique. When you spatchcock a bird and roast it flat in a screaming-hot cast-iron skillet, something magical happens. All that liquid gold—the chicken schmaltz—renders down and bathes torn day-old buttermilk biscuits, frying them until they are shatteringly crisp on the bottom and pillowy on top. Right at the finish line, I toss in peppery mustard greens, a splash of sharp cider vinegar, and, yes, my secret weapon: a dash of fish sauce for an umami backbone that makes those greens sing. My biggest tip for making this your own? Don't shy away from the heat. Let that cast-iron get smoking hot so you build a gorgeous crust on the bird, and feel free to swap the mustard greens for collards depending on what's fresh at your local market. It is heritage food, reimagined.

- 1 tbsp fresh thyme leaves(finely chopped)
- 1 tsp fresh rosemary(finely minced)
- 4 cloves garlic cloves(finely grated or minced)
- 1 tsp smoked paprika
- 4 cups day-old buttermilk biscuits(torn into rough 1.5-inch chunks (about 3 to 4 biscuits))
- 3 large shallots(peeled and quartered lengthwise)
- 1.5 tbsp olive oil
- 4 cups fresh mustard greens(stemmed and roughly chopped into bite-sized ribbons)
- 0.25 cup low-sodium chicken stock
- 2 tbsp apple cider vinegar

- 0.5 tsp salt(mentioned in step 3 for tossing biscuits)
- 0.5 tsp freshly cracked black pepper(mentioned in step 3 for tossing biscuits)
Instructions
- 1
Preheat your oven to 425°F. Place the 1 4-4.5 lb bird whole chicken, giblets removed breast-side down on a cutting board. Using heavy kitchen shears, cut along both sides of the backbone to remove it completely. Flip the bird skin-side up and press firmly downward on the center of the breastbone with the palms of your hands until you hear a crack and the chicken lies completely flat. Pat the skin thoroughly dry with paper towels, then season both sides evenly with 1 tbsp kosher salt and 1 tsp freshly cracked black pepper.
10 min
Tip: Drying the skin thoroughly is the single most important step for getting that deep, crackling golden crust in a screaming-hot oven.
- 2
In a small mixing bowl, blend together 4 tbsp unsalted butter, 1 tbsp fresh thyme leaves, 1 tsp fresh rosemary, 4 cloves garlic cloves, and 1 tsp smoked paprika until uniform. Gently loosen the skin over the chicken breasts and thighs with your fingers, then spread about two-thirds of the compound butter directly under the skin against the meat. Rub the remaining butter over the outside of the skin.
5 min
Tip: Spreading the seasoned butter under the skin bastes the meat from within while preventing the garlic from scorching on the surface.
- 3
In a 12-inch heavy cast-iron skillet, toss 4 cups day-old buttermilk biscuits and 3 large shallots with 1.5 tbsp olive oil, 0.5 tsp kosher salt, and 0.5 tsp freshly cracked black pepper. Spread the biscuit chunks into an even layer across the skillet bottom, leaving room around the perimeter.
5 min
Tip: Day-old, slightly stale biscuits are key here; fresh soft biscuits will turn to mush, but dry ones absorb the drippings and crisp like cornbread croutons.
- 4
Lay the flattened chicken skin-side up directly atop the bed of biscuit croutons and shallots in the skillet, tucking the wing tips behind the shoulders. Transfer the skillet to the center rack of the preheated oven and roast undisturbed until the skin is deep golden-brown, the biscuit edges are sizzling in rendered fat, and an instant-read thermometer registers 165°F in the thickest part of the breast and 175°F in the thigh, about 45 minutes.
45 min
Tip: If the biscuits around the exposed outer rim start darkening too fast around minute 35, gently slide a loose sheet of foil over just the perimeter of the skillet.
- 5
While the bird roasts, prep your greens and dressing liquid. Stem and chop 4 cups fresh mustard greens. In a measuring cup, whisk together 0.25 cup low-sodium chicken stock, 2 tbsp apple cider vinegar, and 1 tsp fish sauce.
7 min
Tip: The fish sauce won't taste fishy at all; it supplies the rich fermented depth that traditionally comes from salt pork or long-simmered smoked meats.
- 6
Carefully pull the skillet from the oven using heavy oven mitts. Use a pair of tongs and a large spatula to transfer the roast chicken to a carving board. Let the bird rest uncovered for 10 minutes so all the juices redistribute throughout the meat.
10 min
Tip: Don't tent the bird with foil while it rests; trapped steam will soften that hard-earned, shatteringly crisp skin.
- 7
Set the cast-iron skillet containing the sizzling biscuit croutons over medium-low heat on the stovetop. Immediately pour in the chicken stock and vinegar mixture to deglaze the skillet, scraping up any caramelized bits. Add the chopped 4 cups fresh mustard greens directly into the pan, tossing gently with the hot biscuit croutons and pan juices for about 2 to 3 minutes until the greens are just wilted and tender, yet still vibrant green.
5 min
Tip: The hot chicken schmaltz and acidity will quickly soften the bite of the raw mustard greens, balancing the richness of the buttery croutons.
- 8
Carve the rested chicken into 8 pieces: 2 breasts halved, 2 thighs, and 2 drumsticks, along with the wings. Spoon the warm, schmaltz-soaked biscuit croutons, sweet roasted shallots, and wilted mustard greens onto a wide serving platter, then arrange the carved chicken pieces on top, pouring any accumulated board resting juices right back over the meat.
5 min
Tip: Serve immediately while the croutons still have that miraculous contrast of crisp underside and pan-soaked tenderness.
Chef's Notes
Growing up in Atlanta, my Big Mama never let a scrap go to waste. If there were leftover buttermilk biscuits from Sunday breakfast sitting in the breadbox by late afternoon, she'd tear them up and toss them right into the base of her big No. 12 cast iron skillet beneath a whole chicken. In Charleston fine dining, I learned how French and Californian chefs used sourdough to catch roasting juices, but honestly, nobody does it like a Southern grandmother with stale biscuits. The croutons fry in pure chicken schmaltz, developing a glass-crisp crust on the cast-iron bottom while drinking in every drop of thyme-scented juice from above. The peppery punch of mustard greens cut with apple cider vinegar and a stealth dash of fish sauce pulls the whole Sunday supper into perfect, soulful balance.

Heritage recipes with a chef's touch
My grandmother's kitchen in Atlanta is where I learned that food carries history. Every pot of collards, every batch of biscuits, every Sunday roast told stories of resilience, family, and love. I went on to train at the finest restaurants in Charleston and worked my way up through white-tablecloth kitchens. But I always came back to those family recipes—now I cook them with a chef's technique but a grandmother's heart. Because the best food honors where it came from.
