The Pantry Staple That Gives Homemade Fried Chicken Its Seriously Crispy Crunch
The best fried chicken announces itself before you finish the first bite: a crackly coating, a satisfying crunch, and tender meat underneath. Getting that balance at home takes more than piling on flour and hoping the oil behaves. But one small change to the coating can help: replace some of the all-purpose flour with cornstarch. Food writer J. Kenji López-Alt uses that approach in his Southern fried chicken recipe to make the crust lighter, not tough.
The trick is cornstarch, not a secret seasoning blend or restaurant-only equipment. It works particularly well in flour-dredged fried chicken, where the goal is a crisp coating rather than a dense shell. López-Alt found that replacing a quarter of the flour worked well in his testing. Recipe developer Imma Adamu uses a similar proportion in her Southern fried chicken breading: three cups of all-purpose flour to one cup of cornstarch.
Why Cornstarch Makes a Difference
Flour does important work in fried chicken, but it can also cause problems. When wheat flour meets moisture, its proteins can form gluten, the network that gives dough structure. In his fried chicken testing, López-Alt found that his coating had become excessively tough and identified gluten formation as the likely culprit. His solution was to dilute the wheat flour with a starch that would not add more of those proteins.
“First and foremost: cut the protein-rich wheat flour with cornstarch,” López-Alt writes in Serious Eats, explaining that cornstarch adds moisture-absorbing capacity without adding excess protein. He follows that with a useful, concrete finding: “Replacing a quarter of the flour worked well.” That gives home cooks a clear starting point. For a coating with two cups of flour-and-starch mixture, the same proportion means 1½ cups of flour and ½ cup of cornstarch.
This is a swap, not an invitation to keep adding ingredients until the bowl resembles a snowdrift. Season the mixture according to the recipe you are following, then coat the chicken as directed. Adamu’s version combines the flour and cornstarch with baking powder, paprika, garlic powder, onion powder, herbs, and pepper. López-Alt also adds baking powder, which he found helped produce a lighter, crisper crust. Cornstarch is the headline trick, but the complete recipe still matters.
It’s not required for every successful batch of fried chicken. Hunter Lewis’s skillet-fried chicken recipe for Bon Appétit uses an all-flour coating and emphasizes careful oil-temperature control and resting the dredged pieces. That distinction is worth keeping: cornstarch is a well-supported way to improve a flour-based crust, not proof that flour alone cannot work. Think of it as a useful adjustment, not the only route to dinner.
Build a Coating That Crunches and Stays on the Chicken
Start with properly seasoned chicken rather than relying on the breading to provide all the flavor. Adamu marinates her chicken in seasoned buttermilk in the refrigerator for at least four hours or overnight. López-Alt also uses a seasoned buttermilk brine, explaining that it helps address moisture and flavor inside the meat. A crunchy exterior is lovely, but it shouldn’t do all the work while the chicken underneath tastes like an afterthought.
When the chicken comes out of its marinade, let the excess liquid drain before dredging it. Adamu instructs cooks to coat each piece in the flour mixture and shake off the excess. Her recipe also calls for a second dip in buttermilk and breading for those who prefer a thicker coating. López-Alt, however, found that double-dipping made his breading excessively thick and more prone to falling off the breast. More coating is not automatically better; follow the method designed for your recipe.
For extra craggy edges, López-Alt uses another small adjustment: work a couple of tablespoons of buttermilk into the dry breading before coating the chicken. The liquid creates small clumps that become part of the crust, adding more nooks and crannies. This is different from soaking the entire flour mixture or making a batter. The aim is a mostly dry dredge dotted with small clusters, the bits that make the coating especially interesting to bite through.
A brief rest before frying can help the coating adhere. Adamu recommends letting the breaded chicken sit for 10 to 15 minutes while the oil heats. Lewis’s Bon Appétit recipe similarly calls for a 15-minute rest so the coating can hydrate. Keep this step brief and follow the recipe’s instructions; don’t leave raw chicken sitting out for long. Meanwhile, prepare a separate, clean rack for the cooked pieces.

Protect the Crunch From the Frying Pan to the Plate
Once frying begins, pay more attention to temperature than to guesswork. Adamu recommends working in batches because overcrowding lowers the oil’s temperature too quickly and can produce greasy chicken. Her recipe starts the oil at 375°F, while Lewis’s skillet method starts at 350°F and maintains 300°F to 325°F during cooking. Those are different recipe-specific approaches, not interchangeable targets. Choose one complete method and use a frying thermometer to control the temperature.
A golden crust does not tell you whether the center is safely cooked. The USDA’s Food Safety and Inspection Service recommends an internal temperature of 165°F for all poultry, measured with a food thermometer before removing it from the heat. Check the thickest part of the meat rather than relying on the coating’s color or the suggested cooking time. The crust may look ready for its close-up while the center still needs attention.
Finally, give the finished chicken a clean wire rack set over a baking sheet. “Drain the chicken on a wire rack so it’s not sitting in oil or sticking to a paper towel,” Adamu advises. Bon Appétit likewise recommends a rack to preserve the crisp crust and a rest of at least 10 minutes before serving. The payoff comes from the whole sequence: a lighter coating, controlled frying, and a sensible landing spot, not simply tossing cornstarch into the bowl and declaring victory.
