I still remember the first time I tried Costco Chicken Salad Sandwich Recipe straight out of the tub I was hooked after one bite. That creamy, tangy, perfectly seasoned mix had me driving back to the warehouse just for a refill more times than I’d like to admit.
So one weekend, I decided to recreate it at home, and after a few tries, I finally nailed a version that tastes just as good (if not better) piled onto soft bread. I’m sharing my exact method below, along with every little trick I picked up along the way.
Cooking Time
- Prep Time: 20 minutes
- Cooking Time: 20 minutes (if poaching your own chicken)
- Total Time: 40 minutes, plus 30 minutes chilling time
Ingredients
- 3 cups cooked chicken, shredded — rotisserie chicken saves time, but poached chicken breast gives the cleanest flavor
- 1/2 cup mayonnaise — the creamy base, so don’t skimp on a good-quality brand
- 1/4 cup sour cream — adds tang and lightens up the heaviness of straight mayo
- 3 stalks celery, finely diced — go extra fine for that signature Costco crunch
- 1/4 cup sweet onion, finely diced — soaks the sharp bite, use a food chopper for even pieces
- 1 tablespoon fresh lemon juice — brightens the whole mix, skip the bottled stuff if you can
- 1/2 teaspoon garlic powder — rounds out the flavor without overpowering the chicken
- 1/2 teaspoon salt — adjust to taste, especially if your chicken is already seasoned
- 1/4 teaspoon black pepper — freshly cracked makes a noticeable difference
- 1/4 teaspoon celery salt — this is the secret ingredient that makes it taste “just like Costco’s”
- 8 slices soft sandwich bread or 4 croissants — pick something sturdy enough to hold the filling
Note: This recipe serves 4 to 6 people as sandwiches, or makes about 4 cups of chicken salad on its own.
Equipment You Need
- Large mixing bowl — for combining the chicken salad ingredients
- Food processor or sharp knife — to shred or finely chop the chicken
- Vegetable chopper — for quick, even dicing of celery and onion
- Measuring cups and spoons — to keep the dressing ratio balanced
- Airtight storage container — for chilling and storing leftovers
How to Make a Costco Chicken Salad Sandwich Recipe?
This chicken salad comes together in just a few simple stages: cook the chicken (if needed), mix the dressing, fold everything together, and let it chill. I’ll walk you through each part so you get that same creamy, finely shredded texture every single time.
Step 1: Cook and Shred the Chicken
If you’re not using rotisserie chicken, poach chicken breasts in simmering broth for about 20 minutes until fully cooked through. Let the chicken cool slightly, then shred it finely using a food processor or two forks. Fine shreds are key here; chunky pieces won’t give you that classic Costco texture.
Step 2: Mix the Creamy Dressing
In a separate bowl, whisk together the mayonnaise, sour cream, lemon juice, garlic powder, salt, pepper, and celery salt until smooth. This dressing is really the heart of the whole recipe, so taste it before moving on and adjust the seasoning if needed.
Step 3: Combine Chicken, Celery, and Onion
Add the shredded chicken, diced celery, and diced onion into a large bowl. Pour the dressing over the top and gently fold everything together until every piece of chicken is coated evenly and nothing looks dry.
Step 4: Chill Before Serving
Cover the bowl and refrigerate the chicken salad for at least 30 minutes. This resting time lets the flavors meld together and firms up the texture, making it much easier to scoop or spread onto bread.
Step 5: Assemble Your Sandwich
Once chilled, spoon a generous scoop of chicken salad onto your bread of choice. Add lettuce or extra crunch if you like, then top with the second slice and serve right away for the best texture.
Additional Tips for Making This Recipe Better
I’ve made this more times than I can count, and here’s what actually moves the needle for me:
- I always chill my celery and chicken beforehand. Cold ingredients hold their texture much better once mixed.
- I like to add the lemon juice a little at a time and taste as I go, since too much can make the salad taste sharp instead of bright.
- I never skip the celery salt. It’s such a small ingredient, but it’s what makes this taste like the real thing to me.
- I let the salad sit in the fridge overnight when I have time, because the flavor gets even better the next day.
- I use a food processor for the chicken instead of chopping by hand, since it gives me that fine, even texture much faster.
Common Mistakes to Avoid
- I once used chicken that was still warm, and it made the dressing separate and turn watery — always let it cool first.
- I’ve over-mixed the salad before, which mashed the chicken into mush instead of keeping nice shreds, so I fold gently now.
- I used to skip chilling the salad, and honestly the flavor and texture just aren’t the same when you serve it right away.
- I added too much dressing once and it drowned the chicken, so now I add it gradually until it just coats everything.
- I forgot to dice my onion small enough one time, and it overpowered every bite, so I always chop it extra fine now.
How to Serve Costco Chicken Salad Sandwich
I love serving this on toasted brioche or a flaky croissant for a bit of extra richness. For a lighter option, I’ll pile it over a bed of crisp lettuce or stuff it into a lettuce wrap instead of bread. A sprinkle of paprika or fresh chopped parsley on top adds a nice pop of color if you’re serving it for guests.
Pair it with a side of chips, fresh fruit, or a simple green salad to round out the meal. A more filling pasta option like Creamy Spinach Tomato Pasta Recipe can also work well when you’re putting together a larger meal.
Variations
- Swap the mayo for plain Greek yogurt if you want a lighter, protein-packed version.
- Use dairy-free mayo and skip the sour cream for a completely dairy-free option.
- Add dried cranberries and slivered almonds for a sweeter, crunchier cranberry chicken salad twist.
- Mix in a spoonful of Dijon mustard for extra tang and depth of flavor.
- Toss in chopped grapes or apples if you like a hint of natural sweetness in every bite.
- Use canned or leftover shredded chicken as a quick hack when you’re short on time.

Make Ahead and Storage
You can make this chicken salad up to 2 days ahead of time and keep it covered in the fridge until you’re ready to serve. It stays fresh in an airtight container in the refrigerator for about 3 to 4 days, so it’s great for meal prepping lunches. I don’t recommend freezing this recipe, since the mayonnaise-based dressing tends to separate and turn watery once thawed, which really affects the texture.
