Ingredients
  

chicken
  • 4 boneless skinless chicken breasts
pan
  • 2 tbsp olive oil
  • 1 tbsp butter
aromatics
  • 4 garlic cloves Minced
pepperoncini and brine
  • 1 cup pepperoncini peppers With some brine
sauce
  • 1 cup chicken broth
  • 2 tbsp pepperoncini brine From the jar; measure separately
  • 1 cup heavy cream
  • 1 cup parmesan cheese Grated
  • 1 tsp Italian seasoning
seasoning
  • 0.5 tsp salt To taste
  • 0.25 tsp black pepper To taste
  • 1 fresh parsley For garnish

Equipment

  • 1 cast iron skillet

Method
 

Sear the chicken
  1. Season the chicken breasts with salt and black pepper, then heat olive oil in a large skillet over medium-high heat. Sear for 5–6 minutes per side until golden, then remove and set aside.
Build the sauce base
  1. Melt the butter in the same pan, then add minced garlic and cook for 1 minute until fragrant. Keep the heat at medium for a gentle sizzle.
Deglaze and simmer
  1. Add chicken broth and 2 tablespoons pepperoncini brine, stirring to deglaze the browned bits from the pan. Scrape the bottom well, then bring the liquid to a simmer.
  2. Add heavy cream, Italian seasoning, and the whole pepperoncini peppers, then bring everything to a simmer. Reduce to a steady simmer, 180–205°F (82–96°C) if you’re checking, with small bubbles around the peppers.
Finish with parmesan and return chicken
  1. Stir in the parmesan until melted, creating a glossy cream sauce. The sauce should look smooth with a slight yellow-green tint.
  2. Nestle the chicken breasts back into the sauce and cook for 5 more minutes until cooked through and the sauce thickens. You should see the edges of the chicken gently steam and the sauce coat the back of a spoon.
Serve
  1. Garnish with fresh parsley and serve over mashed potatoes, rice, or pasta. Spoon extra pepperoncini cream sauce over the top.

Notes

Pro tip: use jar pepperoncini for the brine and peppers so the sauce gets that tangy, lightly spicy flavor in every bite. Refrigerate leftovers in an airtight container for up to 3 days; reheat gently in a skillet with a splash of broth to loosen the sauce. Freezing isn’t recommended because the cream can separate. Dietary swap: for a lower-fat option, use half-and-half in place of heavy cream, though the sauce may be slightly thinner.
