One-skillet pepperoncini chicken sears chicken thighs, then builds a tangy pan sauce from pepperoncini and their brine in the same skillet before simmering the chicken back in it, ready in about 30 minutes. Deglazing the pan with pepperoncini brine after searing the chicken picks up the browned bits left behind, which is what gives the sauce its depth rather than tasting like plain brine and broth.

Why you'll love this
- Searing the chicken first and setting it aside before building the sauce means the onions and garlic that follow cook in a pan that already carries chicken flavor.
- Covering the skillet for the final 10-12 minute simmer, as the instructions specify, lets the chicken finish cooking through gently in the sauce rather than drying out over direct heat.
Tips for the best result
- Use jarred sliced pepperoncini for convenience, as the recipe's own notes suggest, rather than slicing whole peppers.
- Swap chicken breasts for thighs if preferred, per the recipe's own notes, adjusting the cook time accordingly since breasts cook faster.
Troubleshooting
The chicken is dry when using breasts instead of thighs.
Reduce the cook time, per the recipe's own notes, since breast meat cooks faster than thighs and can dry out if simmered for the full time written for thighs.
The sauce is too tangy.
Use less pepperoncini brine next time, since the 2 tablespoons called for is a starting point and brine strength varies by jar.
Sauce becomes too reduced and intense.
don’t panic! Simply add a splash of chicken broth or water to thin it to your desired consistency. Conversely, if your sauce is too thin, remove the chicken temporarily and simmer the sauce for a few extra minutes to reduce.
Store covered in the refrigerator and reheat gently, adding a splash of broth to loosen the sauce.
The recipe's own notes suggest couscous, rice, or crusty bread to soak up the sauce.
Frequently asked questions
Can I use chicken thighs instead of breasts for One-Skillet Pepperoncini Chicken?
Absolutely! Chicken thighs work wonderfully and stay even juicier. Adjust cooking time to about 5-7 minutes per side until they reach 165°F internally.
Are pepperoncinis very spicy?
No, they’re quite mild with a tangy, slightly sweet flavor. They register only 100-500 units on the Scoville scale, making them family-friendly.
Can I make this dish ahead of time?
Yes! It actually improves with time as flavors meld. Refrigerate for up to 4 days and gently reheat on the stove or microwave.
What’s the best way to thicken the sauce?
Remove the chicken temporarily and simmer the sauce for 3-5 minutes until reduced. For extra thickness, whisk in 1 teaspoon cornstarch mixed with water.
How do I prevent the chicken from drying out?
Don’t overcook it! Use a meat thermometer to reach exactly 165°F, and let it rest for 5 minutes before slicing to retain juices.
