Ingredients for copycat costco chicken salad
Simple pantry staples and fresh ingredients make this creamy, tangy chicken salad irresistible.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Breast 🍗 | 1 ½ lb | Poached for tenderness |
| Mayonnaise 🥄 | ¾ cup | High-quality, full-fat preferred |
| Celery Stalks 🧅 | 2 whole | Finely chopped, crisp |
| Red Seedless Grapes 🍇 | ½ cup | Halved for sweetness |
| Dijon Mustard 🍯 | 1 tbsp | For signature tang |
| Fresh Dill 🌿 | ¼ cup | Chopped, vibrant green |
| Fresh Chives 🌱 | ¼ cup | Finely chopped, mild flavor |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Kosher Salt 🧂 | ½ tsp | Adjust to taste |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |
| Heavy Cream 🥛 | ¼ cup | For extra creaminess |
| Water 💧 | 2 cups | For poaching chicken |
| Bay Leaves 🍃 | 2 whole | For poaching flavor |
The chicken is everything here—poached just right for that tender, juicy bite. Costco’s rotisserie chicken works in a pinch, but poaching gives you control. Use boneless, skinless breasts for even cooking, and don’t skip the bay leaves—they add depth without overpowering. If you’re short on time, Trader Joe’s has pre-cut celery and grapes that save chopping. The grapes? Red seedless are ideal—they stay firm and add that signature sweetness. Fresh herbs are a must, but dried dill at half the amount works if you’re in a bind.
No mayo? Greek yogurt with a splash of lemon juice keeps it creamy but lighter. Short on grapes? Diced apples or pears add sweetness, though they’ll soften faster. The Dijon mustard is non-negotiable for that tang—regular yellow mustard won’t cut it. For extra richness, add a splash of cream cheese to the mayo base. And if you’re prepping ahead, hold off on adding the grapes and herbs until serving—they’ll stay crisp longer. The celery can be prepped a day ahead and stored in the fridge, wrapped in damp paper towels to keep it crisp.
This salad keeps beautifully for 4-5 days in the fridge, though the grapes and herbs will soften over time. For best texture, add them fresh when serving. Portion into containers with a layer of mayo on top to seal out air—keeps it creamy longer. If you’re making it ahead for a party, assemble everything except the grapes and herbs, then mix those in right before serving. The flavor actually improves overnight as everything melds together—trust me on this.
Why You'll Love This Recipe
- Poach in Minutes: I’ll admit, poaching chicken feels fancy—but it’s genius for this recipe. Just simmer the breast in water with bay leaves for 12-15 minutes, and you’ve got tender, juicy meat that shreds like butter. No dry, stringy chicken here—just the perfect base for that creamy, tangy Costco magic.
- Tangy & Sweet Balance: That 1 tbsp Dijon mustard and ½ cup halved grapes? Chef’s kiss. The mustard cuts through the richness of the mayo and heavy cream, while the grapes add a juicy sweetness that makes every bite feel like a little flavor party. It’s not just chicken salad—it’s a flavor experience.
- Leftover Powerhouse: This salad doesn’t just taste good—it lasts. Four to five days in the fridge, and it keeps getting better. Pack it for lunches, serve it at potlucks, or eat it straight from the fridge for a quick lunch. The grapes stay plump, the herbs stay bright, and the creaminess never turns sad.
- Weeknight Secret Weapon: Between poaching the chicken and folding in the herbs, it’s not completely hands-off—but it’s way faster than you’d think. Chop the celery and grapes ahead, and you’re basically just mixing and chilling. Trust me, I’ve made it on nights when I’m starving and need something fast.
Step-by-step instructions for copycat Costco chicken salad
Here's how to recreate that iconic creamy, tangy flavor at home—every bite will taste just like the original.
Poach the Chicken Breast for Perfect Tenderness
In a medium saucepan, combine the 2 cups water, 2 bay leaves, and ½ tsp kosher salt. Bring to a gentle simmer over medium heat—you should see small bubbles breaking the surface, but not a rolling boil. This keeps the chicken moist.
Add the 1½ lb boneless, skinless chicken breast and poach for 12-15 minutes, until the internal temperature reaches 165°F and the meat is no longer pink in the center. The bay leaves infuse subtle herbal notes that mimic the Costco version. Remove the chicken and let it cool completely before shredding—this prevents the salad from turning watery.
Shred and Combine with Creamy Base Ingredients
Once cooled, shred the chicken using two forks until it reaches ¼-inch thick strands. In a large mixing bowl, combine the shredded chicken with ¾ cup mayonnaise, ¼ cup heavy cream, 1 tbsp Dijon mustard, and 1 tbsp lemon juice. The lemon juice brightens the flavors while the mustard adds that signature tang.
Mix thoroughly with a rubber spatula until the chicken is fully coated and the mixture is smooth. Here's the thing—don't overmix or the salad will turn dense. You want a creamy, almost mousse-like texture that holds together beautifully.
Fold in Crunchy and Sweet Elements
Finely chop the 2 celery stalks and halve the ½ cup red seedless grapes. Add them to the chicken mixture along with ¼ cup chopped fresh dill and ¼ cup chopped fresh chives. The celery adds crispness, the grapes provide a subtle sweetness, and the herbs bring freshness that cuts through the richness.
Gently fold everything together until evenly distributed. Taste and adjust seasoning with additional ½ tsp kosher salt or ¼ tsp black pepper if needed. The grapes should be evenly dispersed—this is what gives the Costco version its signature pop of color and texture.
Chill and Serve for Maximum Creaminess
Cover the bowl and refrigerate for at least 1 hour before serving. This chilling time allows all the flavors to meld together perfectly and ensures the salad reaches its ideal creamy consistency. The longer it sits, the better it gets—flavors deepen and the texture becomes even more luxurious.
Serve on toasted bread, in wraps, or with crackers. You'll notice the salad holds its shape beautifully without being dry or greasy. The grapes stay plump, the herbs remain vibrant, and the creamy base coats every bite—just like the Costco version you love.
Pro Tips For Making Copycat Costco Chicken Salad
- Poach at the Right Bubble: DESCRIPTION: That "gentle simmer" isn't just marketing—you want tiny, lazy bubbles breaking the surface, not a rolling boil. I used to crank the heat too high and ended up with rubbery chicken. The bay leaves add depth, but if you skip them, at least don’t let the water boil like it’s auditioning for a soap opera.
- Dry the Chicken First: DESCRIPTION: Pat the poached chicken thoroughly with paper towels before shredding. I learned this after making salad that tasted like it swam in its own juices. Wet chicken = watery salad, and nobody wants that.
- Halve Those Grapes Evenly: DESCRIPTION: Cut the grapes into consistent halves—no whole berries hiding in the mix. The Costco version has uniform sweetness with every bite, not random grape surprises. Use a sharp knife and work in batches if needed.
- Mix Just Until Combined: DESCRIPTION: After folding in the celery and herbs, stop mixing the second everything looks evenly distributed. Overworking turns the salad into a dense paste—this isn’t meatloaf. The texture should be creamy but still light, like a cloud with crunch.
Serving suggestions for copycat costco chicken salad
Toasted Bread Showstopper
I love serving this chicken salad on crusty sourdough or brioche buns—toasted until golden and buttery. The warm, crispy bread soaks up the creamy salad while adding a delightful contrast.
For extra richness, brush the buns with garlic butter before toasting. A sprinkle of everything bagel seasoning on top adds a savory crunch that elevates the dish. 🥖
Wrap It Up Fresh
For a portable lunch option, wrap the salad in whole wheat tortillas or spinach wraps with a layer of provolone cheese. Roll tightly and slice into pinwheels for an impressive presentation.
I like adding a drizzle of honey mustard on the inside before rolling—it adds sweetness that complements the tangy salad. This works perfectly for picnics or work lunches.
Gourmet Cracker Platter
Arrange the chicken salad on a platter with an assortment of water crackers, water biscuits, and pita chips for dipping. I recommend adding a few marinated olives and pickled red onions for extra brightness.
The contrast of textures makes every bite exciting, and it’s a crowd-pleaser at parties. This setup feels fancy but takes just minutes to assemble.
Salad Bar Style
For a fun twist, set up a build-your-own salad bar with the chicken salad as the base. Offer toppings like crumbled blue cheese, crispy bacon bits, or toasted walnuts. I also like adding a side of light vinaigrette so guests can adjust the dressing to their taste.
This interactive approach lets everyone customize their perfect bite while keeping the creamy texture intact.
Breakfast Brunch Upgrade
Transform this salad into a brunch favorite by serving it over scrambled eggs or fluffy pancakes. The creamy chicken salad adds a savory element to sweet breakfast dishes. I love pairing it with crispy hash browns for a hearty, satisfying meal.
The contrast of textures and flavors makes it feel indulgent without being heavy. Perfect for weekend mornings!

Frequently asked questions
Why does this recipe use poached chicken instead of rotisserie?
Poaching gives you perfectly tender chicken with just the right moisture—no dry spots! Rotisserie chicken works in a pinch, but poaching ensures even cooking and that signature Costco-style juiciness. The bay leaves add subtle herbal depth that mimics the store-bought version's flavor profile.
Can I make this salad ahead of time?
This salad tastes even better after 1 hour in the fridge, letting flavors meld. For best texture, hold off adding grapes and herbs until serving. The celery can be prepped a day ahead, stored wrapped in damp paper towels to stay crisp.
What if I don't have fresh herbs?
Dried dill works at half the amount, but fresh is ideal for vibrant flavor. Skip the chives if needed—they're mostly for garnish. The Dijon mustard is key for tang, so don't substitute with regular mustard. For extra freshness, add a pinch of dried tarragon or thyme.
How do I keep the grapes from getting mushy?
Add grapes right before serving to maintain their crispness. For make-ahead salads, use diced apples or pears instead—they soften more gradually. The 1-hour chilling time is crucial for perfect texture in every bite.
Can I use a different type of mayo?
Full-fat mayo creates the ideal creamy texture, but Greek yogurt with lemon juice works for a lighter version. Avoid low-fat mayos—they can make the salad dry. The ¼ cup heavy cream also contributes to that luxurious mouthfeel that makes this salad so addictive.
