Does Adding Jalapeños & Onions to Your Frying Oil Actually Work? Let’s Find Out!

The Science and History Behind Flavor-Infused Frying Oil

Fried chicken is a beloved dish across cultures, but in Southern and Black American cuisine, it holds a special place. People have experimented with various ways to elevate the flavor—using buttermilk marinades, unique seasoning blends, and even alternative frying methods. But does adding jalapeños and onions to your frying oil truly enhance the taste?

The idea behind this hack is that the natural oils and compounds from the jalapeños and onions will infuse into the frying oil, thereby subtly seasoning the chicken as it cooks. This isn’t a new concept; many cultures use infused oils in cooking, such as garlic-infused olive oil in Mediterranean cuisine or chili oil in Asian cooking. However, frying with added aromatics is not as common. The question is: does it actually make a noticeable difference?

Breaking Down the Flavor Infusion Process

The theory behind this method is solid. When you deep-fry food, the high temperature causes the oil to extract some of the flavors from whatever is added to it. However, because deep frying happens quickly, and oil doesn’t penetrate deep into food, the flavor impact may be milder than expected. Jalapeños contain capsaicin, the compound responsible for heat, while onions release natural sugars and sulfur compounds that enhance umami.

In practice, some home cooks claim that frying with jalapeños and onions adds a slight depth of flavor to the crust, making it more aromatic and subtly spicy. However, the impact may not be as strong as seasoning the chicken directly. The flavors tend to linger more in the oil rather than fully infusing into the fried food.

If you’re looking for a pronounced flavor, marinating the chicken in a buttermilk brine with jalapeños and onions beforehand may work better. Alternatively, you can finish the fried chicken with a spicy oil drizzle made from the leftover infused oil.

Jalapeño & Onion-Infused Fried Chicken

If you’re curious to test this method for yourself, here’s a foolproof recipe to get that crispy, flavorful fried chicken.

Ingredients

• 4 bone-in, skin-on chicken thighs (or drumsticks)
• 2 cups buttermilk
• 2 teaspoons salt
• 1 teaspoon black pepper
• 1 teaspoon smoked paprika
• ½ teaspoon cayenne pepper
• 1 teaspoon garlic powder
• 2 cups all-purpose flour
• 1 teaspoon cornstarch (for extra crispiness)
• 1 quart vegetable oil (for frying)
• 1 small onion, sliced
• 1 jalapeño, sliced (seeds removed for less heat)

Instructions

1. Marinate the Chicken
   In a large bowl, mix the buttermilk, salt, black pepper, paprika, cayenne, and garlic powder. Submerge the chicken in the mixture, cover, and refrigerate for at least 4 hours (or overnight for best results).
2. Prepare the Coating
   In a separate bowl, mix the flour and cornstarch. Remove the chicken from the buttermilk and dredge each piece in the flour mixture, ensuring it’s fully coated. Let it sit for 10 minutes to allow the coating to adhere.
3. Heat the Oil
   In a heavy-bottomed skillet or Dutch oven, heat the vegetable oil to 350°F. Add the sliced onions and jalapeños to the oil and fry for about 3-5 minutes until they become golden brown and aromatic. Remove them with a slotted spoon before adding the chicken.
4. Fry the Chicken
   Carefully place the coated chicken pieces into the hot oil. Fry for about 12-15 minutes, turning occasionally, until golden brown and cooked through. The internal temperature should reach 165°F.
5. Rest and Serve
   Remove the chicken from the oil and drain on a wire rack or paper towels. Let it rest for 5 minutes before serving.

Final Verdict: Does This Hack Work?

While adding jalapeños and onions to the frying oil does introduce some aromatic elements, it won’t drastically change the overall flavor of the chicken. The heat from the jalapeños and the sweetness from the onions primarily impact the oil itself rather than deeply penetrating the meat. However, this method does add a mild, smoky undertone to the crust, making it worth a try if you’re looking for a subtle twist on classic fried chicken.

Want bolder flavors? Try seasoning your flour mix with finely ground dried jalapeños or marinate the chicken with fresh jalapeños and onions for a more pronounced kick.
