Prepare the chicken. Butterfly the chicken by cutting the chicken breast in half horizontally and opening it up like a book to create two thinner fillets. I find that cutting it in half is sufficient, but if you want your chicken extra thin, feel free to pound it with a meat tenderizer and a piece of plastic or parchment paper over the chicken.
Season the chicken. This is probably the most important step in making flavorful milanesa de pollo. I don’t season the egg, flour, or breadcrumbs because the best way to ensure that everything is properly seasoned, it’s essential to salt the chicken directly. PRO TIP: I like to season my chicken at least a few hours in advance. Typically I will salt it in the morning and prepare it for dinner. If you’re short on time or forget to salt in advance, do it before preparing all of your other ingredients so it has at least a few minutes to absorb into the chicken. Prepare breading station. In one large plate, add the flour. In a second wide and shallow bowl, beat the eggs. In a third plate, spread out the breadcrumbs.
Bread chicken. First, dredge each chicken cutlet in flour, shaking off any excess. Dip the chicken in the beaten eggs, ensuring it’s fully coated. Press the chicken into the breadcrumbs, coating both sides evenly.
Fry chicken. In a large skillet, heat about ½ inch of vegetable oil over medium heat until hot (you can test by dropping a small piece of breadcrumb in—if it sizzles, the oil is ready). Fry the breaded chicken in batches, cooking for 1-3 minutes per side, until golden brown and fully cooked through. The internal temperature should reach 165°F (74°C). Transfer the fried chicken to a baking sheet with a wire rack over it or a plate lined with paper towels to drain excess oil. Remember to add more oil in between batches when necessary.
Serve and enjoy. Keep it simple and serve your milanesa de pollo with lime wedges, salsa, and a simple salad on the side. Optionally, you can serve it with rice and beans, fries or papitas, in a sandwich (torta de milanesa) with avocado, lettuce, tomato, and mayo.
