This chicken sandwich filling delivers a creamy texture with layers of herb-infused flavor that elevate any sandwich. I developed this recipe for my Atlanta deli, where customers rave about its richness and depth.
The secret lies in balancing tender poached chicken with a velvety sauce made from Greek yogurt, fresh herbs, and a touch of lemon. Each bite offers a perfect harmony of savory, tangy, and aromatic notes.
What sets this apart is its versatility—spread it on crusty bread, tuck it into wraps, or serve it over greens. The filling holds its shape without being dry, making it ideal for meal prep.
Ready in under 30 minutes, this recipe transforms simple ingredients into something extraordinary. Here’s how to make it.
Ingredients for Chicken Sandwich Filling
Simple ingredients deliver a creamy, herb-packed filling that elevates any sandwich instantly.
| Ingredient | Amount | Notes |
|---|---|---|
| Chicken Breast 🍗 | 1 ½ lb | Boneless, skinless, poached until tender |
| Greek Yogurt 🥛 | 1 ½ cups | Full-fat for creaminess |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Parsley 🍃 | ¼ cup | Chopped, flat-leaf preferred |
| Fresh Chives 🌱 | 2 tbsp | Finely chopped for garnish |
| Lemon 🍋 | 1 whole | Zested and juiced |
| Garlic Cloves 🧄 | 2 cloves | Minced for sauce |
| Dijon Mustard 🟡 | 1 tbsp | For depth of flavor |
| Mayonnaise 🥫 | ½ cup | High-quality for richness |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Olive Oil 🫒 | 2 tbsp | For poaching chicken |
| Chicken Broth 🍲 | 2 cups | Low-sodium preferred |
The chicken is the foundation here. Boneless, skinless breasts stay tender when poached—avoid overcooking. Costco or Sam’s Club offer bulk options for meal prep. For the Greek yogurt, full-fat versions (like Fage or Chobani) give that velvety texture. Fresh herbs are non-negotiable; Whole Foods or Trader Joe’s have reliable quality year-round.
No Greek yogurt? Sour cream at half the amount works in a pinch. Dried herbs can substitute (use one-third the quantity), but fresh is ideal. Swap lemon zest for apple cider vinegar if needed. For extra richness, add a spoonful of cream cheese. The Dijon mustard can be replaced with whole-grain mustard for a milder bite.
The filling keeps beautifully for 4-5 days in an airtight container. Poach extra chicken to use in salads or wraps. Leftovers freeze for up to 3 months, though texture may soften slightly upon thawing.

Step-by-Step Instructions for Chicken Sandwich Filling
This method ensures the most tender chicken and a creamy, herb-packed filling every time.
Step 1: Poach the Chicken to Tender Perfection
In a medium saucepan, combine the 2 cups Chicken Broth and 2 tbsp Olive Oil. Heat over medium-high heat until the liquid begins to shimmer—just before boiling. Carefully add the 1.5 lb Chicken Breast, ensuring it’s fully submerged.
Reduce heat to medium-low and maintain a gentle simmer. Poach for 12-15 minutes until the chicken is cooked through and reaches an internal temperature of 165°F. The chicken should feel firm to the touch but still juicy. Remove from the broth and let it cool slightly before shredding with two forks.
Step 2: Prepare the Herb and Citrus Base
In a large mixing bowl, combine the 1.5 cups Greek Yogurt, 0.5 cup Mayonnaise, and 1 tbsp Dijon Mustard. Stir until smooth and fully incorporated. This creates the creamy foundation for your filling.
Finely chop the 0.25 cup Fresh Dill, 0.25 cup Fresh Parsley, and 2 tbsp Fresh Chives. Add these herbs to the bowl along with the zest and juice from the 1 whole Lemon. The fresh herbs and citrus will brighten the filling and add layers of flavor.
Step 3: Incorporate Aromatics and Seasonings
Mince the 2 cloves Garlic Cloves finely and add them to the bowl. Sprinkle in the 1 tsp Salt and 0.5 tsp Black Pepper. These seasonings will enhance the natural flavors of the chicken and herbs.
Mix everything thoroughly until the herbs, garlic, and seasonings are evenly distributed. Taste and adjust the seasoning if needed—this is your chance to balance the flavors before adding the chicken.
Step 4: Combine and Chill for Optimal Flavor
Add the shredded chicken to the mixture and fold everything together gently. The goal is to coat the chicken evenly with the creamy herb mixture without overworking it. This ensures every bite is packed with flavor.
Cover the bowl and refrigerate for at least 1 hour. Chilling allows the flavors to meld together, and the filling will thicken slightly, making it easier to spread. For the best results, let it chill overnight if time permits.
Pro Tips For Making Chicken Sandwich Filling
- Poach the Chicken: Simmer the breasts in lightly salted water with a bay leaf for 12-15 minutes—this keeps them absurdly juicy compared to boiling. I learned this the hard way after dry, stringy chicken ruined my first three attempts.
- Strain the Yogurt: Drain plain Greek yogurt in a fine mesh sieve for 10 minutes to remove excess water, or your filling will be runny. Sounds tedious, but it actually changes the outcome.
- Chop Herbs Fine: Mince the dill, parsley, and chives almost to a paste so they distribute evenly and don’t create awkward leafy bites. My grandmother swore by this, and she was right.
- Season Twice: Salt the chicken as it poaches, then taste and adjust the filling’s seasoning after mixing—yogurt needs more salt than you’d expect. After burning three batches of bland filling, I finally figured out the timing.
Make-Ahead Tips for This Dish
Prep Chicken Ahead
Poach the 1.5 lb Chicken Breast up to 2 days in advance. Store cooked chicken in its poaching liquid in the fridge—this keeps it moist. I learned this trick during my Charleston apprenticeship.
Mix Filling Early
Combine all filling ingredients except chicken up to 1 day ahead. The flavors deepen overnight. Store in an airtight container at 40°F or below. I use my vintage Pyrex bowls for this.
Assemble Before Serving
Shred and mix chicken with the sauce just 2-3 hours before serving. This prevents the chicken from absorbing too much liquid. The texture stays perfect this way.
Portion for Convenience
Divide filling into individual containers for grab-and-go sandwiches. Portion ½ cup per sandwich. This saves time during busy deli service at The Smoky Pig. 💡
Freeze for Later
Freeze filling for up to 3 months in freezer-safe bags. Thaw overnight in the fridge. Stir well before using as separation may occur.
Revive Leftovers
If filling seems dry after storage, stir in 1-2 tbsp Greek Yogurt. This restores creaminess. Avoid microwaving—it can make the chicken rubbery.

Frequently Asked Questions
Can I use rotisserie chicken instead of poaching?
Shred 1.5 lb of rotisserie chicken and skip the poaching step. It saves time and adds smoky depth. Just reduce added salt, as rotisserie chicken is often pre-seasoned.
What bread pairs best with this filling?
Opt for sturdy breads like sourdough, ciabatta, or whole grain to hold the creamy texture. Toasting helps prevent sogginess. A sprinkle of arugula adds freshness.
How do I prevent the filling from being watery?
Drain the poached chicken well and pat it dry before shredding. Also, chill the filling for at least 1 hour to thicken. If needed, add 1 tbsp breadcrumbs to absorb excess moisture.
Can I make this dairy-free?
Swap Greek yogurt for coconut yogurt or vegan mayo. Use a dairy-free broth for poaching. The herbs and lemon will still deliver bold flavor.
