Ingredients Equipment Method Notes

Ingredients
  

  • 1.5 lbs boneless, skinless chicken breasts or thighs, pounded to even thickness
  • 1/3 cup all-purpose flour
  • 2 tsp kosher salt, divided
  • 1 tsp black pepper
  • 1 tsp garlic powder
  • 2 tbsp olive oil
  • 2 tbsp unsalted butter
  • 1 medium yellow onion, thinly sliced
  • 4 cloves garlic, minced
  • 1 cup low-sodium chicken broth
  • 1/2 cup sliced pepperoncini
  • 2 tbsp pepperoncini brine from the jar
  • 4 oz full-fat cream cheese, softened and cubed
  • 1/2 cup heavy cream
  • 1 tsp dried oregano
  • Fresh parsley, chopped for garnish

Equipment

  • Large skillet (10-12 inch)
  • Cutting board
  • Chef's knife
  • Measuring cups and spoons
  • Mixing plate or shallow dish
  • Tongs
  • Whisk
  • Instant-read thermometer (recommended)

Method
 

  1. Prepare the chicken: On a plate, combine the flour, 1 teaspoon of salt, black pepper, and garlic powder. Dredge each chicken piece thoroughly in the mixture, shaking off any excess.
  2. Sear the chicken: Heat olive oil in a large skillet over medium-high heat until shimmering. Add the chicken pieces without crowding the pan (cook in batches if needed). Cook undisturbed for 5-7 minutes per side, until a deep golden-brown crust forms. Transfer chicken to a plate (it will not be fully cooked through).
  3. Sauté aromatics: Reduce heat to medium. Add butter to the skillet. Once melted, add the sliced onion and a pinch of salt. Sauté for about 5 minutes, until softened. Add the minced garlic and cook for 1 minute until fragrant.
  4. Deglaze the pan: Pour in the chicken broth and pepperoncini brine, using a whisk or spatula to scrape up all the browned bits (fond) from the bottom of the pan. Add the sliced pepperoncini and dried oregano. Bring the mixture to a simmer.
  5. Create the creamy sauce: Reduce heat to low. Whisk in the cubed cream cheese until it is completely melted and the sauce is smooth. Stir in the heavy cream until fully incorporated. Return the sauce to a gentle simmer.
  6. Finish cooking: Return the seared chicken and any accumulated juices to the skillet, nestling them into the sauce. Spoon sauce over the chicken. Cover the skillet and simmer on low for about 10 minutes, or until the chicken reaches an internal temperature of 165°F (74°C).
  7. Rest and serve: Remove the skillet from the heat and let it rest, covered, for 5 minutes. The sauce will thicken further upon standing. Garnish with chopped fresh parsley and serve immediately over mashed potatoes, rice, or pasta.

Notes

For best results, ensure the chicken is pounded to an even thickness for uniform cooking. Do not skip the flour dredge, as it aids browning and sauce thickening. If the sauce seems too thick after resting, thin it with a splash of chicken broth. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days; reheat gently on the stovetop over low heat to prevent the sauce from breaking. For a spicier dish, add a pinch of red pepper flakes with the oregano.
