Start by taking your chicken breasts and gently pounding them to an even thickness. This ensures they cook evenly and stay juicy. Season both sides with salt and pepper to taste.
In one bowl, whisk the eggs. In another bowl, place a generous amount of flour, and in a third bowl, pour the breadcrumbs. This triplet setup will help you create that crispy coating.
Coat each chicken breast in flour, shaking off the excess. Then, dip it into the beaten eggs, allowing any excess to drip off, and finally coat it in the breadcrumbs. Press down gently to ensure the breadcrumbs adhere well.
In your skillet or deep fryer, heat about an inch of peanut oil over medium-high heat. You’ll want the oil to reach around 350°F (175°C) for the perfect frying temperature.
Carefully add the breaded chicken to the hot oil, cooking for about 5-7 minutes on each side, or until golden brown and cooked through. Use a meat thermometer to ensure the internal temperature reaches 165°F (75°C). Once done, transfer to a plate lined with paper towels to absorb any excess oil.
While the chicken is frying, mix together the mayo, sriracha sauce, minced garlic, chipotle chili pepper, smoked paprika, and a pinch of salt and pepper in a bowl. Adjust the spice level to your liking by adding more sriracha if desired.
Toast your buns lightly, then spread a generous amount of spicy mayo on the bottom half. Place a fried chicken breast on top, followed by fresh lettuce and slices of tomato. Top it off with the other half of the bun.
Slice the sandwich in half for easy handling, serve with your favorite side, and enjoy your homemade Spicy Breaded Fried Chicken Sandwich!
