This quick, one-pan chicken dish features tender strips of chicken breast simmered in a rich, garlicky cream sauce with sweet bell peppers, onions, and tangy pepperoncini peppers. The brine from the peppers adds a bright, slightly spicy kick that balances the creamy sauce beautifully. It’s incredibly easy, ready in about 30 minutes, and perfect served over steamed rice, buttered noodles, or with warm garlic bread. Even picky eaters usually love it!

Ingredients (for 4 servings)

• 2 lbs boneless, skinless chicken breasts, cut into thin strips
• Salt and black pepper, to taste
• 1–2 tablespoons avocado oil (or olive oil)
• 1 cup finely chopped onion
• 1 cup sliced red or orange bell pepper
• 4 large garlic cloves, minced
• 1 cup chicken broth
• 1 tablespoon Italian seasoning
• 1 cup heavy cream (or half-and-half for a lighter version)
• ¾–1 cup freshly grated Parmesan cheese, divided
• 1 cup sliced pepperoncini peppers (mild to medium heat; from a jar, drained but reserve a little brine)
• 2–3 tablespoons pepperoncini brine (optional, for extra tang)
• Fresh parsley, chopped (for garnish)

For Serving:

• Steamed white rice or buttered noodles
• Garlic bread (optional)

Instructions

1. Season and sear the chicken: Season the chicken strips with salt and black pepper. Heat 1–2 tablespoons oil in a large skillet over medium-high heat. Add the chicken in a single layer (work in batches if needed) and sear until golden brown on both sides, about 3–4 minutes per side. The chicken doesn’t need to be fully cooked yet. Remove to a plate and set aside.
2. Cook the vegetables: Reduce heat to medium. In the same skillet, add the chopped onion and sliced bell pepper. Cook for 4–5 minutes until the onion is translucent and the peppers soften. Stir in the minced garlic and cook for 30–60 seconds until fragrant.
3. Build the sauce: Pour in the chicken broth and add the Italian seasoning. Bring to a gentle simmer and let it reduce by about half (5–7 minutes). This concentrates the flavor.
4. Turn the heat to low. Slowly stir in the heavy cream. Add ¾ cup of the grated Parmesan and stir until the cheese melts and the sauce is smooth and creamy. Add the sliced pepperoncini peppers and a splash (2–3 tablespoons) of the pepperoncini brine for extra tang and flavor.
5. Return the seared chicken (and any juices) to the skillet. Stir gently to coat everything in the sauce. Cover and simmer on low for 5 minutes, or until the chicken is cooked through and the sauce has thickened slightly.
6. Taste and adjust salt or pepper if needed. Sprinkle with the remaining Parmesan and chopped fresh parsley just before serving.
7. Serve hot over steamed white rice or buttered noodles, with garlic bread on the side if desired.

Tips for Success

Use heavy cream for the richest, silkiest sauce; half-and-half works for a lighter version but won’t thicken quite as much. Pepperoncini add a mild, tangy heat — remove the seeds if you want it even milder, or use banana peppers for a sweeter, less spicy option. Freshly grated Parmesan melts better and gives superior flavor. The dish reheats well; add a splash of broth or cream when reheating to loosen the sauce.

This creamy chicken pepperoncini skillet is comforting, flavorful, and comes together fast — ideal for weeknights or when you want something that feels a little special. It’s one of those recipes that looks and tastes like more work than it actually is.

Give it a try and let me know whether you served it over rice or noodles, or how spicy you liked the pepperoncini — I’d love to hear!

Enjoy every creamy, tangy bite!
