Begin by marinating the chicken. In a medium-sized bowl, combine the bite-sized chicken pieces with the dill pickle juice. Cover and let marinate in the refrigerator for at least 30 minutes to allow the flavors to infuse into the chicken.
After the chicken has marinated, drain the pickle juice, discarding it, and transfer the chicken to a clean bowl. Pour in the buttermilk, ensuring all the chicken pieces are submerged. Let them soak for another 30 minutes; this step helps to tenderize the chicken and enhances flavor.
While the chicken is soaking, prepare the coating. In a separate mixing bowl, whisk together the all-purpose flour, cornstarch, powdered sugar, garlic powder, onion powder, paprika, black pepper, and salt until well combined. This mixture will create a delicious crunchy texture and flavor for the nuggets.
In a deep pan or fryer, heat vegetable oil to 350°F (175°C). Ensure you have enough oil to completely cover the nuggets while frying. Use a thermometer to maintain the correct temperature for best results.
Once the chicken has soaked in the buttermilk, remove the pieces one at a time, allowing any excess liquid to drip off. Dredge each chicken piece in the seasoned flour mixture, making sure they are evenly coated for a satisfying crunch.
Carefully place the coated chicken nuggets into the hot oil in small batches, avoiding overcrowding the pan. Fry the nuggets for approximately 4-5 minutes or until they turn a beautiful golden brown and are cooked through (the internal temperature should reach 165°F or 74°C). Keep a close eye on the oil temperature and adjust the heat if necessary to prevent burning.
Once the nuggets are cooked, use a slotted spoon to transfer them to a paper towel-lined plate, allowing any excess oil to drain off. Repeat the frying process with the remaining chicken pieces.
Serve the crispy chicken nuggets hot with your favorite dipping sauces, which could include ranch, honey mustard, or BBQ sauce.
Notes
For an inviting presentation, arrange the crunchy nuggets on a large platter. Accompany them with small bowls of various dipping sauces for guests to choose from. To add a touch of color, garnish the platter with fresh parsley or sprigs of dill.
