Ingredients
  

Ingredients
  • 2 tablespoons butter
  • 1 small garlic clove finely minced
  • 1/4 cup chicken broth
  • 2 tablespoons fresh lemon juice
  • 1 teaspoon lemon zest
  • 1 to 2 tablespoons capers drained
  • 1 tablespoon fresh parsley chopped
  • Freshly ground black pepper to taste
  • Salt only if needed

Method
 

Instructions
  1. Start with the skillet
  2. After cooking your chicken milanesa, transfer the cutlets to a wire rack or serving plate. Carefully pour off most of the frying oil from the skillet, leaving about 1 teaspoon behind along with the browned bits on the bottom of the pan.
  3. Those browned bits add extra savory flavor to the finished sauce.
Build the sauce
  1. Place the skillet over medium heat and add the butter. Once it begins to melt, stir in the minced garlic and cook for 20 to 30 seconds, just until fragrant. Do not let the garlic brown.
  2. Add the chicken broth, fresh lemon juice, lemon zest, and drained capers. Stir well, scraping the bottom of the skillet to loosen the browned bits.
  3. Let the sauce simmer for 1 to 2 minutes, until it reduces slightly and begins to look glossy.
Finish and serve
  1. Remove the skillet from the heat. Stir in the chopped parsley and a few grinds of black pepper. Taste before adding salt, since capers are naturally salty.
  2. Spoon a small amount of sauce over the chicken milanesa and serve the rest on the side. This keeps the breading crisp while still giving every bite that buttery lemon-caper flavor.

Notes

Tips
For a richer, silkier sauce, whisk in 1 additional tablespoon of cold butter after removing the skillet from the heat.
Use freshly squeezed lemon juice for the cleanest, brightest flavor.
Keep the sauce light: chicken milanesa should be drizzled, not submerged.
Serve with arugula or mixed greens tossed with lemon, shaved Parmesan, and a little olive oil.
