Costco Chicken Salad Recipe With Grapes: Sweet and Creamy Picnic Classic

This chicken salad delivers that classic deli taste with a sweet, creamy texture that’s hard to resist. The addition of grapes brings a refreshing burst of flavor that balances the richness perfectly.

I’ve refined this recipe to capture the same quality you’d find at Costco, using simple ingredients and a straightforward method. The key is in the balance—creamy dressing, tender chicken, and just the right amount of sweetness from the grapes.

What makes this dish stand out is its versatility. Serve it on croissants, crackers, or straight from the bowl for a satisfying meal that feels special without the fuss.

Perfect for picnics, lunches, or a quick dinner when you want something creamy and comforting. Here’s how to make it at home.

Ingredients for Costco Chicken Salad Recipe with Grapes

Simple ingredients create this creamy, classic deli-style chicken salad with sweet grapes.

The chicken is the foundation here. Costco rotisserie chicken works perfectly—just shred the breast meat (the good stuff, not the pre-shredded kind). For the grapes, red seedless are ideal for their natural sweetness and vibrant color. Celery adds the essential crunch, so don’t skip it. Best to grab these from Whole Foods or your local grocery store for peak freshness.

No mayonnaise? Greek yogurt at a 1:1 ratio keeps it creamy but lighter. Almonds can be swapped for pecans or walnuts—whatever you’ve got in the pantry. If you’re out of Dijon, regular mustard with a pinch of sugar gets you close. The sour cream can be omitted, but the flavor won’t be as rich (worth the extra minute).

This keeps well in the fridge for 3-4 days—perfect for meal prep. Store in an airtight container, and give it a quick stir before serving. Freezing isn’t recommended because the texture changes (trust me on this one).

Step-by-Step Instructions for Chicken Salad With Grapes

This method ensures a perfectly balanced texture with creamy richness and bright, sweet accents.

Step 1: Prepare and Chop the Base Ingredients

Start by dicing the 2 cups cooked chicken breast into uniform ½-inch pieces. I find that shredding works too, but dicing gives a more consistent bite. Place the chicken in a large mixing bowl.

Next, halve the 1.5 cups red seedless grapes lengthwise. This exposes more surface area for the dressing to cling to and ensures a burst of sweetness in every bite. Add the grapes to the bowl with the chicken.

Step 2: Add the Crunch and Aromatics

Finely dice the 0.75 cup celery into small, even pieces—this ensures every spoonful has a hint of fresh crunch. Thinly slice the 0.25 cup green onions for a mild, oniony bite without overpowering the other flavors.

Toast the 0.5 cup almonds in a dry skillet over medium heat for 3-4 minutes until lightly golden and fragrant. Let them cool, then chop roughly. Add the celery, green onions, and almonds to the bowl with the chicken and grapes.

Step 3: Whisk the Creamy Dressing

In a separate bowl, combine the 0.75 cup mayonnaise, 0.25 cup sour cream, 1 tbsp Dijon mustard, and 1 tbsp apple cider vinegar. Whisk until smooth and fully emulsified.

Season the dressing with 0.5 tsp salt, 0.25 tsp black pepper, and 0.5 tsp dried dill. The dill adds a subtle, herby depth that complements the sweetness of the grapes. Taste and adjust seasoning if needed.

Step 4: Combine and Chill for Optimal Flavor

Pour the dressing over the chicken mixture. Using a silicone spatula, fold everything together gently but thoroughly. You want every ingredient coated without breaking up the grapes or almonds. The mixture should look creamy but not soggy.

Cover the bowl with plastic wrap and refrigerate for at least 1 hour. This chilling time allows the flavors to meld and the dressing to thicken slightly. For the best texture, don’t skip this step—it transforms the salad from good to exceptional.

Serve chilled on a bed of lettuce, in sandwiches, or with crackers. The salad keeps well in the refrigerator for up to 3 days, though the almonds may soften slightly over time.

Common Mistakes When Making Great costco chicken salad recipe with grapes

Over-Mixing the Salad

Once you add the dressing, fold everything together gently with a spatula. Over-mixing will break up the grapes and almonds, turning your salad into a mushy mess. I aim for 8-10 folds max to keep the texture intact. 💪

Skipping the Chill Time

Resist the urge to dig in right away. Refrigerating for at least 1 hour lets the flavors meld and the dressing thicken. I’ve made the mistake of skipping this, and the result was a watery, underwhelming salad.

UsingPre-Shredded Chicken

Avoid pre-shredded rotisserie chicken from Costco—it’s often dry and stringy. Instead, grab a whole rotisserie chicken and shred the breast meat yourself. The texture difference is night and day.

Wrong Grape Choice

Stick to red seedless grapes for the ideal sweetness and color. Green grapes can be too tart, and black grapes might overpower the dish. Halve them lengthwise so every bite gets that juicy pop.

Over-Toasting Almonds

Toast the almonds over medium heat for just 3-4 minutes until golden. Burnt almonds add a bitter flavor that ruins the balance. Let them cool before chopping to keep them crisp.

Dressing Too Thick

If your dressing seems too thick, thin it with 1-2 tbsp milk or chicken broth. A dressing that’s too heavy will coat the ingredients unevenly and feel gloppy on the palate.
