Ingredients for copycat costco chicken salad
High-quality chicken, creamy dressing, and crisp vegetables—this is the secret to Costco's iconic flavor.
| Ingredient | Amount | Notes |
|---|---|---|
| Rotisserie Chicken 🍗 | 3 cups | Shredded, skin removed |
| Mayonnaise 🥛 | 1 cup | Dijon-style preferred for tang |
| Plain Greek Yogurt 🍦 | ½ cup | Full-fat for creaminess |
| Celery Stalks 🧅 | 2 whole | Thinly sliced, crisp |
| Red Onion 🧅 | ¼ cup | Finely diced, sharp flavor |
| Lemon Juice 🍋 | 1 ½ tbsp | Freshly squeezed, brightens flavors |
| Dijon Mustard 🍯 | 1 ½ tsp | For depth of flavor |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground for best flavor |
| Garlic Cloves 🧄 | 2 cloves | Minced, for subtle depth |
| Fresh Dill 🌿 | 2 tbsp | Chopped, for freshness |
| Paprika 🌶️ | ¼ tsp | Smoked for subtle warmth |
| Worcestershire Sauce 🍯 | ½ tsp | For umami richness |
The rotisserie chicken makes all the difference—look for a store-bought one with crispy skin and plenty of juices. Trader Joe's and Costco's own brand are top-tier, but any reputable rotisserie will work. If you're using raw chicken, poach it first in a mix of chicken broth and lemon juice for that signature tenderness. The key is shredding it just fine enough to hold its shape—no pulverizing! For extra flavor, season the chicken with Diamond Crystal kosher salt, black pepper, and a pinch of paprika before cooking.
No rotisserie chicken? Poached chicken breast works perfectly—just season it well and shred it after cooking. Swapping out the mayo? Greek yogurt at half the amount cuts calories without sacrificing creaminess, but trust me, the full-fat version delivers that iconic texture. The celery needs to stay crisp, so don't chop it too early—slice it right before mixing. For the red onion, white or yellow gives the best sharpness, but red adds a pretty pop of color. The Worcestershire sauce is non-negotiable—it brings that deep, savory note that makes this salad taste like the real deal.
This salad tastes even better the next day once everything melds together. Store the dressing and chicken separately in airtight containers for up to 5 days—just mix them together when ready to eat. For parties, make the dressing ahead and keep the chicken and veggies separate until serving to maintain that perfect crunch. The dressing alone keeps for 1 week in the fridge, making this a great make-ahead option for lunches or gatherings. If you're prepping for a crowd, double the recipe—it scales perfectly.

Step-by-step instructions for copycat Costco chicken salad
Here's how to recreate that signature creamy, tangy chicken salad with perfect texture and flavor.
Shred and Prepare the Rotisserie Chicken
Start by removing all skin and bones from the 3 cups rotisserie chicken, then shred it into bite-sized pieces using two forks. I like to pull the meat apart gently but thoroughly—you want pieces that are tender but still hold their shape. Place the shredded chicken in a large mixing bowl.
Here's the thing—if your chicken has any remaining fat or skin, trim it away now. Fat can make the salad greasy, and skin adds unwanted texture. The goal is that clean, creamy mouthfeel that makes this salad so irresistible. Keep the shredded chicken at room temperature while you prepare the other ingredients.
Mix the Creamy Base
In a medium bowl, combine the 1 cup mayonnaise, ½ cup plain Greek yogurt, 1½ tablespoons lemon juice, 1½ teaspoons Dijon mustard, ½ teaspoon Worcestershire sauce, 1½ teaspoons salt, and ½ teaspoon black pepper. Whisk vigorously for about 1 minute until the mixture is completely smooth and well blended.
This is where the magic happens—the yogurt adds that signature tang while keeping it creamy, and the lemon juice brightens everything up. I always use Dijon mustard here because it has that subtle depth that regular mustard lacks. If the mixture looks too thick, you can add a teaspoon of water to loosen it slightly, but it should be thick enough to coat the chicken well.
Add Aromatics and Herbs
Finely dice the 2 celery stalks and ¼ cup red onion, then mince the 2 garlic cloves. Add these to the chicken along with the 2 tablespoons fresh dill and ¼ teaspoon paprika. Stir gently to distribute everything evenly throughout the chicken.
The celery and onion add that classic crunch and freshness, while the garlic and paprika bring subtle warmth. I like to chop the celery and onion very finely so they're barely noticeable in each bite—just enough to add texture without overpowering. The fresh dill is crucial for that bright, herby finish that makes this salad taste so fresh.
Combine and Chill
Pour the creamy base over the chicken mixture and fold everything together gently but thoroughly using a large spoon. Be careful not to overmix—just enough to combine all the ingredients evenly. The salad should look creamy, with visible chunks of chicken and celery throughout.
Cover the bowl and refrigerate for at least 2 hours, preferably overnight. This chilling time is essential—it allows all the flavors to meld together perfectly and gives the chicken time to absorb all that creamy goodness. The longer it chills, the better the texture becomes, so don't skip this step if you can help it.
Pro Tips For Making Copycat Costco Chicken Salad
- Trim the Fat First: That leftover skin and grease from the rotisserie chicken is where things go wrong—it turns your creamy salad into something greasy and heavy. Spend 2 minutes picking it all out before shredding, and your salad will stay silky smooth every bite.
- Whisk the Dressing Hard: Skimping on the whisking means streaks of mayo and lumps of yogurt. Give that creamy base a full minute of vigorous whisking—you’re not just mixing, you’re emulsifying. The result? A velvety texture that coats the chicken perfectly.
- Dice the Onion Tiny: Big chunks of red onion mean a mouthful of sharp bite. Pulse them in a food processor or chop them so fine they’re almost invisible—just enough to add brightness without overpowering the creamy base.
- Chill It Properly: Stuffing this salad in the fridge for 2 hours isn’t enough—let it sit overnight if you can. The flavors meld, the chicken absorbs the dressing, and the texture becomes perfectly cohesive. (Yes, I know you’re impatient, but trust me on this.)
Regional styles of copycat costco chicken salad
Southern-Style BBQ Twist
In my hometown of Georgia, we love adding a touch of Southern flair to this salad. Swap out the red onion for ½ cup finely diced sweet Vidalia onion—it keeps the sharpness but with a milder sweetness.
I also toss in ¼ cup chopped pickles (like Dill Pickle Relish) for that tangy crunch that cuts through the richness. The pickles add a nostalgic touch that reminds me of family gatherings at my grandmother’s kitchen table. 🌟
Appalachian Mountain Variation
If you’re near the Appalachian Mountains, you’ll find folks using ½ cup cooked ham mixed into the chicken for extra depth. I like to add 1 tbsp apple cider vinegar to the creamy base, which brightens up the flavors with a hint of sweetness.
This version feels like a cross between a classic chicken salad and a comforting Southern dish. The vinegar also helps balance the richness of the mayo and yogurt. 💛
Charleston-Style Seafood Fusion
For a Charleston twist, I replace 1 cup of the chicken with 1 cup flaked cooked shrimp (like those from Hatch & Rose seafood market). Add 1 tbsp chopped parsley and a pinch of Old Bay seasoning to the creamy base for a coastal flair.
The shrimp adds a delicate sweetness that pairs perfectly with the creamy dressing. This version feels like a seafood twist on a classic—just like the dishes I’d serve at The Smoky Pig. ✨
Lowcountry Shrimp & Chicken
In the Lowcountry, we love our seafood, so I blend 1 cup cooked shrimp and 1 cup chicken together. I also add 1 tbsp chopped green onions and a dash of hot sauce (like Tabasco) for a kick.
The shrimp brings a briny note that complements the creamy dressing beautifully. This version is perfect for summer gatherings—light but flavorful. 🔥
Kansas City-Style BBQ Spice
For a Kansas City-inspired twist, I add ½ tsp smoked paprika and ¼ tsp garlic powder to the creamy base. I also include 2 tbsp chopped walnuts for a nice crunch.
The smoky spices give the salad a deeper, more complex flavor profile that reminds me of the BBQ pits I’ve worked in across the Midwest. This version feels like a fusion of comfort food and regional pride. 🌶️

Frequently asked questions
Why does this chicken salad taste so much better after chilling?
The 2-hour to overnight chilling period lets all the flavors meld together perfectly. The chicken absorbs the creamy dressing more evenly, and the celery stays crisp without turning soggy. This step is what gives it that restaurant-quality texture and depth of flavor—don't skip it!
Can I use regular mayonnaise instead of Dijon-style?
You can, but Dijon-style adds that subtle tang and depth that makes it taste more like the Costco version. If you're using regular mayo, add an extra ½ teaspoon of lemon juice to brighten up the flavors. The texture will still be creamy, but the flavor profile might be slightly milder.
How do I keep the celery from getting soggy?
Slice the celery right before mixing it into the salad to preserve its crispness. If you prep it ahead, store it separately in a damp paper towel-lined container in the fridge. Adding the celery just before serving ensures it stays crunchy and doesn’t turn mushy in the creamy mixture.
What if I don’t have fresh dill?
You can substitute with 1 tablespoon of dried dill (use half the amount of fresh) or even a pinch of dried tarragon for a similar herbal note. If you’re in a pinch, a mix of parsley and a tiny bit of thyme can work too—just know the flavor will be slightly different but still delicious.
Can I make this salad ahead of time for a party?
Store the dressing and chicken separately in airtight containers for up to 5 days. Mix them together just before serving to keep the celery crisp. The dressing alone keeps for 1 week, making this perfect for meal prep or gatherings—just assemble when ready to eat!
