Ingredients + Tips

Ingredients Breakdown

Butter (2 tablespoons)
Butter provides richness and helps brown the chicken beautifully. You can substitute olive oil if needed, but butter adds depth to the sauce.

Chicken (2 lbs, thinly sliced)
Boneless, skinless chicken breasts or thighs both work well. Thin strips cook quickly and stay tender in the creamy sauce.

Sea Salt & Black Pepper (1 teaspoon each)
Simple seasoning that enhances the natural flavor of the chicken.

White Onion (1, diced)
Adds sweetness and body to the sauce as it softens and caramelizes slightly.

Garlic (2 tablespoons, diced)
Fresh garlic is essential here. It infuses the sauce with savory warmth.

Chicken Stock (½ cup)
Deglazes the pan and builds the foundation of the sauce. Low-sodium stock is ideal so you can control the salt level.

Roasted Red Peppers (½ cup, sliced)
These add subtle sweetness and a smoky undertone that pairs beautifully with the pepperoncini.

Heavy Cream (1 cup)
Creates the luxurious, velvety sauce. For best results, use full-fat cream.

Parmesan Cheese (½ cup, freshly shredded)
Adds umami and thickens the sauce. Freshly grated Parmesan melts more smoothly than pre-shredded cheese.

Italian Seasoning (1 tablespoon)
A blend of herbs that ties the dish together and reinforces the comforting flavor profile.

Pepperoncini Peppers (½ cup, drained)
The star ingredient. Mildly tangy, slightly spicy, and incredibly flavorful.

Ingredient Tips for Best Results

• Slice the chicken evenly so it cooks at the same rate.

• Use freshly grated Parmesan to avoid grainy sauce texture.

• Drain the pepperoncini well so excess brine doesn’t overpower the sauce.

• Don’t skip deglazing the pan—those browned bits add huge flavor.

Step-by-Step Instructions

Step 1: Brown the Chicken

In a large, heavy skillet, melt the butter over medium-high heat. Season the chicken strips with salt and black pepper, then add them to the hot pan. Brown on all sides, turning every couple of minutes. This should take about 8 minutes total. The chicken doesn’t need to be fully cooked yet.

Remove the chicken from the skillet and set aside.

Step 2: Sauté the Aromatics

In the same skillet, add the diced onion and garlic. Cook for about 5 minutes, stirring frequently, until the onion is soft and lightly golden. This step builds the aromatic base of the sauce.

Step 3: Deglaze and Reduce

Pour in the chicken stock and add the roasted red peppers. Bring the mixture to a gentle simmer, scraping up any browned bits from the bottom of the pan. Let it reduce by about half, which should take around 5 minutes.

Step 4: Build the Cream Sauce

Turn the heat off briefly. Slowly whisk in the heavy cream and Parmesan cheese until smooth and fully combined. Turning the heat off prevents the sauce from breaking.

Step 5: Finish the Dish

Return the skillet to medium-high heat. Add the Italian seasoning, pepperoncini peppers, and the reserved chicken along with any juices. Simmer gently until the sauce thickens and the chicken reaches an internal temperature of 165°F (74°C).

If the sauce becomes too thick, add a splash of chicken stock to loosen it.

Step 6: Serve

Remove from heat and serve immediately over your favorite base.

Tips for Best Results

• Control the tang: Start with ½ cup pepperoncini and add more if you like extra zip.

• Avoid overheating the cream: High heat can cause separation—gentle simmering is key.

• Let the sauce rest briefly: It thickens slightly as it cools for a perfect consistency.

• Taste before serving: Pepperoncini and Parmesan both add saltiness, so adjust seasoning at the end.
