  • White onion: adds sweetness when cooked down slowly
  • Diced garlic: gives a fragrant punch that complements the creamy sauce
  • Chicken stock: adds depth and helps create the sauce base
  • Roasted red peppers: bring color and a sweet earthiness
  • Heavy cream: is what makes the sauce indulgently smooth and luscious

Step-by-Step Instructions

Sear the Chicken:
Melt butter over medium high heat in a large heavy skillet. Season thin chicken strips with sea salt and ground pepper. Add to the skillet and brown on all sides, turning every couple of minutes for about eight minutes total. Remove chicken even if not fully cooked through yet as it will finish cooking later.
Sauté Garlic and Onion:
Add diced garlic and white onion to the pan and cook over medium heat until they become soft and golden about five minutes. This step builds a sweet and aromatic base for the sauce.
Deglaze and Reduce:
Pour in chicken stock and add sliced roasted red peppers. Let the mixture simmer until it reduces by half to concentrate the flavors, approximately five minutes.
Make the Creamy Sauce:
Turn off the heat and slowly whisk in heavy cream and shredded parmesan cheese. This prevents the cream from curdling and ensures the sauce becomes silky smooth.
Combine and Finish Cooking:
Raise heat back to medium high. Stir in Italian seasoning and pepperoncini peppers. Return the chicken to the pan and let everything simmer so the sauce reduces by half and the chicken reaches an internal temperature of 165 Fahrenheit. Add extra chicken stock if the sauce gets too thick.
Remove from heat and serve:
Serve over your favorite vegetables, pasta, rice or simply enjoy on its own.

Storage Tips

Cool leftovers completely before storing. Place in an airtight container and refrigerate up to three days. To reheat gently warm on the stovetop with a splash of chicken stock to loosen the sauce.

Ingredient Substitutions

You can swap heavy cream for half and half plus a tablespoon of flour for a lighter sauce but expect a less rich texture. If you don’t have pepperoncini peppers try banana peppers or mild pickled jalapeños for a different twist.

Serving Suggestions

Serve this skillet dish over cooked pasta, creamy mashed potatoes, or steamed rice to soak up the sauce. Roasted vegetables on the side add a nice contrast to the creamy texture.

Frequently Asked Questions

What cut of chicken works best for this dish?

Thin strips of chicken breast or thigh work well as they cook quickly and evenly, absorbing the sauce flavors.

Can I adjust the spice level with pepperoncini?

Yes, the amount and type of pepperoncini can be modified to taste, whether sliced, whole, or rings, to balance heat and tang.

How do I prevent the creamy sauce from curdling?

Adding cream off the heat and whisking gently before reheating slowly helps maintain a smooth, velvety sauce texture.

Is it necessary to brown the chicken before adding the sauce?

Browning seals in moisture and develops flavor, providing a more savory base for the sauce and tender chicken.

What are suitable side dishes to serve with this skillet?

Steamed vegetables, pasta, or rice complement the rich sauce and tender chicken perfectly, balancing the meal.

Ingredients

  • Poultry

  • 2 lbs chicken, thinly sliced strips
  • Seasonings

  • 1 tsp sea salt
  • 1 tsp ground black pepper
  • 1 tbsp Italian seasoning
  • Vegetables and Peppers

  • 1 white onion, diced
  • 2 tbsp garlic, diced

  • ½ cup pepperoncini peppers, drained and sliced or whole
  • Liquids and Dairy

  • 2 tbsp unsalted butter
  • ½ cup chicken stock
  • 1 cup heavy cream
  • ½ cup Parmesan cheese, shredded

Instructions

1.

1. Prepare the pan and brown chicken: Melt the butter in a large heavy skillet over medium-high heat. Season the chicken with salt and pepper, then add to the pan. Brown on all sides by turning every few minutes, about 8 minutes total.

2.

2. Sauté aromatics: Remove chicken from the pan and set aside. Add the diced garlic and onion to the skillet and sauté until browned, approximately 5 minutes.

3.

3. Deglaze and reduce: Pour in the chicken stock and add roasted red peppers. Let the mixture reduce by half over medium heat, about 5 minutes.

4.

4. Incorporate cream and cheese: Turn off the heat temporarily. Whisk in the heavy cream and Parmesan cheese slowly and vigorously to form a smooth sauce.

5.

5. Combine ingredients and finish cooking: Return heat to medium-high and add Italian seasoning, pepperoncini peppers, and the browned chicken. Let the sauce reduce by half, ensuring the chicken reaches an internal temperature of 165°F. Add extra chicken stock if sauce thickens too much.

6.

6. Serve: Remove the pan from heat and serve the chicken and sauce over vegetables, pasta, rice, or enjoy as is.

Notes

  1. It is acceptable for the chicken to be slightly undercooked after browning since it will finish cooking in the sauce. Use a meat thermometer to confirm the final internal temperature.
