Crispy Chicken Caramelized Onions (Printable)

Golden panko-crusted chicken topped with sweet caramelized onions and melted mozzarella-cheddar.

# What You'll Need:

→ Chicken

01 - 4 boneless, skinless chicken breasts
02 - 1 cup all-purpose flour
03 - 2 large eggs
04 - 1½ cups panko breadcrumbs
05 - ½ cup grated Parmesan cheese
06 - 1 teaspoon garlic powder
07 - 1 teaspoon paprika
08 - Salt and black pepper, to taste
09 - 2 tablespoons olive oil

→ Caramelized Onions

10 - 2 large yellow onions, thinly sliced
11 - 2 tablespoons unsalted butter
12 - 1 tablespoon olive oil
13 - 1 teaspoon sugar
14 - ¼ teaspoon salt
15 - 1 teaspoon balsamic vinegar (optional)

→ Cheese & Assembly

16 - 1½ cups shredded mozzarella cheese
17 - 1 cup shredded cheddar cheese
18 - 2 tablespoons chopped fresh parsley (optional, for garnish)

# How-To Steps:

01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large skillet, heat butter and olive oil over medium-low heat. Add the sliced onions, sugar, and salt. Cook, stirring occasionally, until the onions are deep golden and soft, about 20-25 minutes. Stir in balsamic vinegar during the last few minutes if desired. Set aside.
03 - Pat the chicken breasts dry and season both sides with salt, pepper, garlic powder, and paprika. Dredge each breast in flour, dip in beaten eggs, then coat thoroughly with the panko and Parmesan mixture.
04 - Heat olive oil in a large skillet over medium-high heat. Sear the chicken for 2-3 minutes per side until golden brown. Do not cook through. Transfer the browned chicken to the prepared baking sheet.
05 - Top each chicken breast with a generous spoonful of caramelized onions, then sprinkle evenly with mozzarella and cheddar cheese.
06 - Bake for 15-18 minutes, or until the chicken is cooked through and the cheese is melted and bubbly.
07 - Garnish with chopped fresh parsley before serving.

# Expert Advice:

01 -
  • The contrast between that shatteringly crisp panko crust and the soft, sweet onions underneath is genuinely addictive.
  • It feels like something you would order at a comfort food restaurant, but it comes together with everyday ingredients you probably already have.
  • Double the onions and you will never regret it, trust me on that one.
02 -
  • Do not skip the pan searing step or you will lose the textural contrast that makes this dish special, the oven alone will not create a crispy crust.
  • Cook the onions on true medium low heat, rushing them on high heat creates burnt edges instead of sweet, jammy ones.
  • Let the breaded chicken rest for five minutes before searing so the coating adheres properly and does not slide off in the pan.
03 -
  • Press the panko mixture onto the chicken with your palms rather than just flipping it, firm pressure makes the coating stick through both the sear and the bake.
  • If your chicken breasts are thick, place them between plastic wrap and pound them to even thickness before breading so everything cooks evenly.
