Salads
This Cape Cod chicken salad recipe transforms Costco's rotisserie chicken into a restaurant-worthy dish with crisp celery, tart apples, and a light mayo dressing that clings perfectly to greens. The secret lies in finely chopping all ingredients—especially the celery and herbs—to create that signature crunch without sogginess.
I developed this version after realizing Costco's bulk ingredients (like Kirkland brand mayo and pre-washed greens) make it easier than ever to recreate this New England classic at home.
The magic happens in the dressing, where a blend of mayo, Dijon mustard, and a touch of lemon brightens the flavors without overpowering the chicken.
Traditional Cape Cod chicken salad relies on celery and herbs for texture, but this version adds crisp apples and grapes for a modern twist that still feels nostalgic. The key is mixing everything just before serving to maintain that ideal crunch—no one likes a mushy salad.
What you'll end up with is a salad that's light yet satisfying, perfect for summer lunches or potlucks. The rotisserie chicken from Costco shatters easily, the celery stays crisp, and the dressing binds everything together without making the greens wilt.
It's the kind of dish that feels special but comes together in under 20 minutes—ideal for busy weeknights or meal prep.
Serve this salad with crusty bread, crackers, or alongside grilled fish for a complete Cape Cod-inspired meal. The recipe scales easily for a crowd, making it perfect for gatherings where you want to impress without spending hours in the kitchen. Let's get started!

The rotisserie chicken from Costco is a game-changer—two whole birds give you plenty of meat to shred. Look for the Kirkland Signature brand for the best quality, and always remove the skin before shredding. The apples and grapes should be crisp, so Fuji apples and red seedless grapes work perfectly. For the greens, stick with Costco's Kirkland brand spring mix—it's pre-washed and stays fresh longer. The celery needs to be finely chopped; a food processor makes this step quick, but a sharp knife works too.
No Dijon mustard? Yellow mustard in a pinch, though it won't have the same depth. The lemon juice can be swapped for apple cider vinegar at half the amount if you're out, but fresh lemon is ideal. If you're making this ahead, hold off on adding the grapes until serving—they soften fast. For extra crunch, toss in 1/4 cup chopped walnuts. The dressing ratio is key: 3 parts mayo to 1 part mustard keeps it light but flavorful. Don't skip the herbs—they're what make this salad taste fresh and bright.
This salad keeps well in the fridge for 3-4 days, but the grapes and celery lose their crunch over time. Store the dressing separately and mix just before serving. The bread pairs perfectly—sourdough or baguette slices work best. For a crowd, double the recipe; the ingredients scale easily. Leftovers? It reheats surprisingly well for a salad—just warm the chicken portion gently and mix again with the dressing.
Why You'll Love This Recipe
- Costco Hack Ready: I swear by that rotisserie chicken—shredding it takes five minutes, and the flavor? Already done. No raw chicken handling, no waiting for it to cook, just grab and go.
- Sweet-Savory Magic: That apple and grape combo sounds weird until you try it—the crunch cuts through the mayo, and the grapes add this burst of sweetness that makes every bite feel like a little reward. (Yes, even on a Tuesday night.)
- Lunchbox Legend: Between us, this is my go-to for school lunches or work snacks. The grapes stay fresh longer than most, and the celery adds that satisfying crunch kids (and adults) actually eat. Pack it in a jar, and you’ve got a meal that doesn’t need reheating.
- Leftovers That Shine: Make a double batch—trust me, you will. The salad keeps for days in the fridge, and it’s just as good cold as it is fresh. Spread it on crackers, toss it in a wrap, or eat it straight: zero waste, all win.
Step-by-step instructions for Cape Cod chicken salad
Here's how to transform Costco rotisserie chicken into a bright, crunchy salad that stays fresh without turning soggy.
Shred and Chop All Ingredients Precisely
Remove all skin and bones from the 2 whole Costco rotisserie chickens, then shred the meat using two forks or your hands. I like to pull the meat into fine, even strands—this prevents clumps and ensures every bite has that signature Cape Cod texture. Transfer the shredded chicken to a large mixing bowl.
Next, finely chop the 2 cups celery stalks into small dice—about ⅛-inch pieces. For the 1.5 cups red apples, cut them into small cubes that'll stay crisp rather than turning mushy. Halve the 1 cup red seedless grapes and remove any stems. Chop the 0.25 cup fresh dill and 0.25 cup fresh chives into tiny pieces—these herbs add freshness without overpowering.
Combine Wet Ingredients for Perfect Balance
In a separate small bowl, whisk together the 0.75 cup Kirkland Signature mayo, 1 tbsp Dijon mustard, and 1 tbsp lemon juice until smooth. This trio creates a tangy, creamy base that won't make the salad heavy. Taste the mixture—it should be bright and slightly acidic, not sweet. If needed, add a pinch of the 0.5 tsp salt to balance the flavors.
Pour the dressing over the shredded chicken and stir gently to coat evenly. The key here is to distribute the mayo lightly—just enough to moisten without making the chicken soggy. Add the chopped celery, apples, grapes, dill, and chives, then sprinkle with the remaining 0.25 tsp black pepper. Mix everything together carefully so the grapes and apples stay intact.
Assemble the Salad for Maximum Crunch
Spread the 8 cups pre-washed spring mix evenly across a large serving platter or individual plates. The greens should form a base that covers the entire surface—this keeps the salad fresh and prevents wilting. Using a large spoon, carefully mound the chicken mixture on top, creating an even layer without overcrowding.
Here's the secret to keeping it crisp: don't mix everything together until serving. The spring mix stays freshest when kept separate from the chicken mixture until the last moment. If you're serving immediately, simply spoon the chicken salad over the greens and garnish with extra chopped chives.
Serve with Crusty Bread for the Ultimate Experience
Slice the 1 lb crusty bread into thick pieces and toast lightly if desired—this adds a satisfying crunch that complements the salad perfectly. Serve the chicken salad immediately with the bread on the side. The contrast between the cool, crunchy salad and warm bread creates a restaurant-quality meal.
For best results, assemble the salad just before serving. The spring mix will stay crisp, the grapes will maintain their snap, and the chicken will remain tender without absorbing excess moisture. This method delivers all the bright flavors of classic Cape Cod chicken salad without the mayo cling.
Pro Tips For Making Cape Cod Recipe Chicken Salad Costco
- SHRED COLD CHICKEN: Shove that Costco rotisserie chicken in the fridge for at least 2 hours before shredding—it’ll pull apart like butter instead of fighting you. I learned this the hard way after wrestling with sticky, warm chicken that turned my salad into a gluey mess.
- COARSE THE CELERY: Skip the tiny dice—chop the celery into ¼-inch chunks so you actually taste it. Too fine, and it disappears into the mayo; too big, and it’s just crunchy afterthoughts. Aim for "bite-sized but not overwhelming."
- DRAIN THE GRAVY: Wipe down the rotisserie chicken with paper towels before shredding—you want flavor, not a soggy salad. That extra moisture turns your perfect texture into a sad, watery pile. Trust me, 30 seconds of blotting saves the whole dish.
- ADD APPLE LAST: Toss the apple in just before serving, or it’ll turn to mush in the mayo. Use a sharp knife and cut it into ⅛-inch pieces—small enough to eat but big enough to keep its crunch. (Yes, even if you’re impatient like me.)
Storing and reheating this dish
Fridge Storage Tips
Store your Cape Cod chicken salad in an airtight container with a tight-fitting lid to keep the greens crisp and prevent sogginess. I use glass Pyrex containers because they maintain freshness longer than plastic.
Keep it refrigerated at 40°F or below for up to 3 days—the grapes and celery stay crunchy if stored properly. 🥬
Dressing Separation
To maintain texture, store the dressing (mayo, mustard, lemon juice) separately in a small sealed container. Mix it with the chicken mixture just before serving—this prevents the celery and apples from getting mushy. The Kirkland Signature mayo stays fresh for 5-7 days in the fridge when stored this way.
Freezer-Friendly Prep
You can freeze the chicken mixture without the grapes or greens for up to 3 months. Thaw overnight in the fridge, then add fresh grapes and spring mix when ready to serve.
The celery and herbs lose texture when frozen, so omit them if prepping ahead. Use a quart-sized freezer bag for easy storage and reheating.
Reheating Without Ruin
If you need to warm leftovers, gently reheat only the chicken portion in a microwave-safe bowl for 30-45 seconds on 50% power. Stir in the dressing and fresh ingredients just before serving—this keeps everything crisp.
Avoid boiling the salad, as this turns the mayo greasy and the greens limp. 🔥
Grapes and Greens
Add the spring mix and grapes only when ready to eat—they soften quickly when refrigerated. For extra crunch, toss in 1/4 cup chopped walnuts or toasted sunflower seeds right before serving. These additions keep the salad interesting even when reheated.
Bread Pairing
Toast crusty bread separately and serve on the side—it stays fresh longer than if stored with the salad. For meal prep, wrap slices in parchment paper and freeze for up to 2 weeks. Reheat in a toaster or oven for 3-5 minutes at 350°F to restore crispness.

Can I make this recipe ahead of time?
Yes, but with a few adjustments. Prep the chicken mixture and dressing 1 day ahead and store separately. Add the grapes and greens only when serving. For a crowd, assemble everything 2 hours before serving—this gives the flavors time to meld without losing crunch. The key is keeping components separate until the last moment.
What if I don't have Dijon mustard?
No problem! Use yellow mustard in a 1:1 ratio, though it won't have the same depth of flavor. For a tangier alternative, try apple cider vinegar (1/2 tbsp) mixed with the mayo. The lemon juice in the recipe already provides acidity, so you can skip the mustard entirely if needed—just adjust the salt to taste.
