Peperoncini Chicken Salad Sandwiches
This chicken salad is for anyone who has ever looked at a standard mayo chicken salad and thought it needed more going on. Shredded rotisserie chicken tossed with chopped hot cherry peppers, Greek peperoncini, a full can of diced green chilies, crunchy diced celery, red onion, and a creamy mayo-mustard dressing that holds it all together. Every element contributes something, the hot cherry peppers bring heat and a vinegary brightness, the peperoncini add their characteristic mild tang, the green chilies add a gentle, earthy heat that runs through the whole salad, and the celery and red onion add crunch and sharpness. Together they produce a chicken salad that is bold, layered, and distinctive in a way that makes plain versions feel like a missed opportunity.
The 30-minute refrigerator rest before serving is the step that transforms a good chicken salad into an exceptional one. The pepper brines infuse the chicken, the mustard and mayo settle into the other ingredients, and everything comes together into something more cohesive and fully flavored than it is immediately after mixing. Make it the night before and it’s even better. This is the chicken salad that earns a permanent place in the weekly rotation.
Why You’ll Love This Recipe
The pepper combination is the move. Hot cherry peppers for heat and sharpness, Greek peperoncini for their mild, tangy brine, and diced green chilies for a gentle, earthy background heat. Three different peppers that each do something different and together produce a chicken salad with real character.
Rotisserie chicken makes it effortless. Already cooked, already seasoned, already perfect for shredding. There is no poaching, no seasoning, no guessing about doneness.
The chill time matters. Thirty minutes in the refrigerator is the difference between a salad where you can taste each ingredient separately and one where everything has melded into something cohesive and deeply flavored.
It keeps for four days. Make a full batch on Sunday and lunch is handled for most of the week. The flavor deepens every day it sits in the fridge.
It works in every format. Piled high on toasted sourdough, tucked into a croissant, spooned into lettuce cups, or eaten straight from the container with a fork. This chicken salad earns its place in every format.
Ingredients Needed to Make Peperoncini Chicken Salad
One bowl and straightforward ingredients. Here’s what you need:
- Shredded rotisserie chicken (two pounds of pre-cooked chicken makes this the fastest possible version of a from-scratch chicken salad)
- Hot cherry peppers, chopped (adds a vinegary heat that is present throughout every bite)
- Greek peperoncini, chopped (the mild, tangy, brine-forward pickled pepper that gives this salad its defining flavor)
- Canned diced green chilies, drained (adds a gentle earthy heat in the background that supports the other peppers without announcing itself)
- Mayonnaise (the creamy base of the dressing; use a brand you enjoy eating on its own)
- Mustard, yellow or Dijon (adds tang and sharpness to the dressing; Dijon is the more complex choice)
- Red onion, finely diced (adds a sharp, slightly sweet bite throughout)
- Celery, diced (adds crunch and a fresh, slightly bitter contrast to the rich mayo dressing)
- Salt and black pepper
How to Make Peperoncini Chicken Salad
One bowl, 15 minutes of prep, and a 30-minute rest.
Step 1: Prepare the Chicken
Pull the rotisserie chicken from the carcass and shred it into bite-sized pieces by hand or with two forks. Removing the skin before shredding produces a leaner, more uniform result. Place the shredded chicken in a large mixing bowl.
Step 2: Prep the Vegetables and Peppers
Finely dice the red onion and celery. Chop the sliced hot cherry peppers and the Greek peperoncini into smaller pieces so they distribute evenly throughout the salad rather than appearing in large chunks that dominate individual bites. Drain the canned diced green chilies thoroughly.
Step 3: Make the Dressing
In a small bowl, whisk together the mayonnaise and mustard until smooth and completely combined. The mustard doesn’t just add flavor — it acts as an emulsifier that keeps the dressing from separating as it sits with the other ingredients.
Step 4: Combine
Add the chopped peppers, drained green chilies, diced red onion, and diced celery to the bowl with the shredded chicken. Pour the mayo-mustard dressing over everything and stir until every piece of chicken and vegetable is evenly coated in the dressing.
Step 5: Season and Chill
Taste the salad and add salt and black pepper as needed. Keep in mind that the peperoncini and hot cherry peppers both contribute salt from their brine, so taste before adding. Cover the bowl tightly with plastic wrap or transfer to a sealed container and refrigerate for at least 30 minutes before serving.
Step 6: Serve
Serve piled generously on sandwich bread, croissants, or toast, or spooned into lettuce cups for a lighter presentation.
Storing and Make-Ahead Tips
Store in a sealed airtight container in the refrigerator for up to 3 to 4 days. The flavor develops and improves over the first day as the pepper brines infuse further into the chicken and the dressing fully melds with all the other ingredients. Stir before serving each time since some of the dressing can settle.
If adding cucumbers or cabbage for extra crunch, add them fresh right before serving rather than storing them mixed into the salad since both release water over time and can make the salad slightly watery after a day or two.
How to Serve Peperoncini Chicken Salad
The most satisfying way to eat this salad is on thick-sliced toasted sourdough or a toasted croissant with a crisp lettuce leaf and a few extra peperoncini on the side. The combination of the tangy, slightly spicy chicken salad and the warm, crunchy toast is one of those simple combinations that works perfectly every time.
For a picnic or gathering, serve on a platter surrounded by sliced bread, crackers, and small cucumber rounds for scooping, and let guests build their own. This is a natural choice for a large-format casual lunch where people can serve themselves.
Frequently Asked Questions About Peperoncini Chicken Salad
What are peperoncini and how are they different from other pickled peppers?
Peperoncini are mild Italian pickled peppers with a slightly sweet, tangy, gently spiced flavor and a characteristic brine that is less sharp than banana peppers and significantly milder than sport peppers or hot cherry peppers. Greek peperoncini specifically tend to be slightly milder and more wrinkled than the Italian variety. Both work in this recipe. The brine they’re packed in carries a significant amount of their flavor and a small splash of it stirred into the salad adds an extra layer of tangy depth that the chopped peppers alone don’t provide.
How spicy is this chicken salad?
As written, this salad has a noticeable but moderate heat level. The hot cherry peppers provide the most direct heat, the peperoncini add a mild tang with very little heat, and the diced green chilies add a gentle background warmth. For a milder version, reduce or omit the hot cherry peppers and replace with additional peperoncini. For a spicier version, increase the hot cherry peppers, add a pinch of red pepper flakes to the dressing, or stir in a small amount of a Louisiana-style hot sauce.No Content
Can I use canned or poached chicken instead of rotisserie?
Yes. Canned chicken, well-drained, works as a convenient substitute for a pantry-only version. Poached chicken breasts or thighs shredded by hand are excellent if you want to control the seasoning more precisely. Rotisserie chicken is recommended because it’s already seasoned, already cooked, and produces the most flavorful result with the least effort, but any cooked shredded chicken works in this recipe.
Why let the salad chill before serving?
The 30-minute minimum chill time allows the pepper brines to migrate into the chicken, the mustard to fully emulsify with the mayo, and all the individual flavors to meld into a cohesive whole rather than tasting like separate ingredients in a bowl. A freshly mixed chicken salad is good. A chicken salad that has had time to rest and develop is noticeably better. The overnight version is the most developed and the most recommended if time allows.

Notes

Dijon mustard adds more complexity and sharpness than yellow mustard. Either works but Dijon is the upgrade worth making.
