Ingredients for air fried chicken quarters

The secret to crispy-core perfection lies in these 13 game-changing ingredients—each playing a crucial role in that legendary crunch.

The buttermilk is non-negotiable—it’s the magic potion that tenderizes while creating that signature tang. Full-fat works best (none of that skim nonsense), and you’ll want it cold straight from the fridge. For the chicken quarters, bone-in, skin-on is essential—those bones keep the meat juicy, and the skin crisps to golden perfection. I always grab mine from Costco when they’re on sale, but any grocery store’s butcher section will have them. Look for quarters that are similar in size—uneven pieces cook at different rates. The kosher salt? Diamond Crystal is my go-to because it dissolves perfectly in the brine without leaving grit. Freshly cracked pepper and garlic powder elevate the flavor, while smoked paprika gives that restaurant-quality color.

No buttermilk? Mix 1 cup milk with 1 tbsp vinegar or lemon juice—let it sit for 5 minutes to curdle. Running short on egg whites? Use aquafaba (chickpea brine) at the same ratio. For the flour, King Arthur or Bob’s Red Mill are my top picks—they’re light and create the perfect crispy crust. Can’t find smoked paprika? Regular paprika plus a pinch of liquid smoke works in a pinch. The cornstarch is what takes this from ‘good’ to ‘mind-blowing crispy’—don’t skip it. And that olive oil spray? Misto brand is my secret weapon for even distribution in the air fryer. Pro tip: Toss the cornstarch-flour mix in a ziplock bag and shake it on—zero mess.

The buttermilk brine keeps for 3 days in the fridge—make extra for dipping sauces or pancakes. Chicken quarters stay fresh for 2 days raw in the fridge, but once cooked, they reheat beautifully—just 5 minutes at 350°F to restore crispiness. For meal prep, cook a double batch and freeze the extras on a tray before bagging—3 months max. Store cooked chicken airtight with a paper towel to absorb moisture. And that leftover buttermilk? Whip it with sugar for biscuits or use it to marinate steak—trust me, it’s a pantry superstar.

Step-by-step instructions for buttermilk brined air fried chicken quarters

Here's how to transform ordinary chicken quarters into restaurant-quality crispy bites with a juicy core.

In a large bowl, whisk together the 1 cup buttermilk, 1 tablespoon lemon juice, 1 tablespoon olive oil, 1 tablespoon Diamond Crystal kosher salt, 1 teaspoon garlic powder, and 1 teaspoon paprika until fully combined. The buttermilk should be slightly thickened and have a tangy aroma. This brine will infuse the chicken with flavor and create that perfect crispy exterior we're after.

Place the 2 lb chicken quarters in a resealable plastic bag and pour the buttermilk mixture over them. Seal the bag and massage it gently to ensure every piece of chicken is coated. Let the chicken marinate in the refrigerator for at least 4 hours or overnight for maximum flavor penetration. The longer it marinates, the more tender and flavorful the final result will be.

In a shallow bowl, combine the 1 cup all-purpose flour, 2 tablespoons cornstarch, 1 teaspoon ground black pepper, and 1 teaspoon paprika. The cornstarch is crucial here—it creates that extra crispy texture we're aiming for. In another bowl, beat the 2 whole large egg whites until frothy but not stiff. This light coating will help create an airy, crispy crust.

Remove the chicken from the brine and pat it dry thoroughly with paper towels. This step is critical—any moisture on the chicken will prevent the breading from adhering properly. Work in batches if needed to keep the chicken dry and ready for breading.

Dredge each chicken quarter in the flour mixture, pressing gently to ensure an even coating. Shake off any excess flour, then dip into the egg whites, allowing any excess to drip off. Finally, return each piece to the flour mixture, pressing firmly to create a thick, even crust. This triple-dredging technique guarantees that crispy, golden-brown exterior we're after.

Place the breaded chicken quarters on a wire rack set over a baking sheet. This allows air to circulate around each piece, promoting even cooking and maximum crispiness. Let them rest at room temperature for 10 minutes before air frying. This resting period helps the breading adhere better and prevents the chicken from steaming instead of crisping.

Preheat your air fryer to 375°F for 5 minutes. Lightly spray the air fryer basket with the vegetable oil spray—this ensures the chicken doesn't stick and promotes even browning. Arrange the chicken quarters in a single layer, leaving space between each piece for proper air circulation. Avoid overcrowding, as this will lead to uneven cooking.

Air fry the chicken for 20 minutes, then flip each piece and spray lightly with more oil. Continue air frying for an additional 10-15 minutes until the chicken reaches an internal temperature of 165°F and the exterior is a deep golden brown with crispy skin. The cornstarch in the breading will give you that satisfying crunch while keeping the inside juicy and tender.

Transfer the cooked chicken quarters to a cutting board and tent loosely with aluminum foil. Let them rest for 5 minutes before serving. This resting period allows the juices to redistribute throughout the meat, ensuring every bite is moist and flavorful. During this time, you can chop the 0.25 cup fresh thyme leaves for garnish if desired.

Serve the chicken quarters immediately, garnished with the chopped thyme leaves. The skin should be crispy with a slight crunch, and the meat should be juicy with a tender, succulent texture. Each bite should deliver that perfect balance of crispy exterior and moist interior that makes this recipe truly special.

Serving suggestions for this dish

Classic Dipping Sauces

No crispy chicken is complete without a dipping sauce! My go-to is honey mustard—mix 3 tbsp Dijon mustard, 2 tbsp honey, 1 tbsp apple cider vinegar, and a pinch of cayenne pepper.

For a creamy option, blend ½ cup Greek yogurt, 1 tbsp lemon juice, 1 tsp garlic powder, and salt to taste. Serve in small bowls or squeeze bottles for easy dipping. 🍯

Salad Pairings

Balance the richness of air-fried chicken with a refreshing cucumber-avocado salad. Toss 2 cups chopped cucumber, 1 avocado, ¼ cup red onion, and ¼ cup crumbled feta. Drizzle with 2 tbsp olive oil and 1 tbsp lemon juice.

The cool, crunchy textures contrast perfectly with the crispy chicken. For a heartier option, add 4 cups mixed greens and top with ¼ cup toasted almonds.

Game Day Spread

Turn your chicken into the star of a game day spread. Serve with crudités (carrot sticks, celery, and bell pepper strips) and ranch or blue cheese dressing for dipping. Add tortilla chips for scooping and pickled jalapeños for heat.

For a complete meal, toss together a Mexican street corn salad with 2 cups corn kernels, ¼ cup cotija cheese, 1 tbsp chili powder, and 1 tbsp lime juice. 🏈

Sandwiches & Wraps

Use the chicken quarters to make crispy chicken sandwiches with your favorite bread. Pile 2 slices of brioche with ¼ cup coleslaw mix, 2 tbsp BBQ sauce, and a quartered piece of chicken.

For a lighter option, wrap the chicken in a spinach tortilla with 2 tbsp Greek yogurt sauce, ¼ cup shredded carrots, and 2 slices of avocado. The crispy skin holds up perfectly to sandwich fillings.
