The Story Behind the Recipe
Some recipes become favorites not because they’re fancy… but because they’re dependable. Cozy. Familiar. The kind that turns a busy weekday or a lazy Sunday into something delicious with barely any effort. And if there’s one recipe that fits that description perfectly, it’s the famous Costco chicken salad.
I don’t know about you, but every time I walk through Costco and spot that giant container of creamy, dreamy chicken salad in the deli case, something inside me just smiles. It has that unmistakable flavor — tender chicken, a creamy dressing, a savory tang, a hint of sweetness, and just the right amount of crunch. It’s simple, but it never tastes boring. It’s comforting, but never heavy. And it just works — on sandwiches, crackers, salads, croissants, wraps, or straight from the fridge with a spoon.
But there was one day — a busy afternoon when I didn’t feel like driving to the store — when the craving was VERY real. And that was the moment this Homemade Costco Chicken Salad Recipe was born. I pulled leftover rotisserie chicken from the fridge, chopped celery, measured out mayo, sprinkled seasoning, and mixed everything together. When I took that first bite… it was Costco-level perfection. Creamy, savory, delicious, and familiar — but also somehow even better, because it was homemade with love.
From that moment on, this recipe became a staple in my kitchen — for packed lunches, summer picnics, sandwich platters, baby showers, busy weeknights, and every time my family wants something quick, comforting, and unbelievably delicious.
If you’ve ever wished you could scoop generous spoonfuls of Costco chicken salad without making the trip, this recipe is for you. It tastes just like the original — maybe even better — and you can make it in minutes with simple ingredients and love.
My hope is that this Homemade Costco Chicken Salad Recipe brings convenience, comfort, and joy to your table again and again — the same way it has for mine.

🍗 For the Chicken Salad Base
- Rotisserie chicken (shredded or diced) — white and dark meat blend

Rotisserie chicken is the secret weapon — it’s tender, juicy, and already perfectly seasoned to mimic the classic Costco texture.

- Lemon juice
- Sugar (just a hint — the key to the Costco flavor!)

- Black pepper
- Garlic powder
This dressing is what transforms simple chicken into that signature Homemade Costco Chicken Salad Recipe flavor we crave.
🌟 Optional Add-Ins (Customize Just the Way You Love It)
- Fresh dill or parsley for brightness
- Paprika or celery seed for seasoning depth
- Finely diced sweet pickles for extra tang
- Sour cream or Greek yogurt for a lighter dressing

Step-by-Step Cooking Instructions
Making this Homemade Costco Chicken Salad Recipe is soothing and simple — the kind of kitchen moment where everything comes together effortlessly and beautifully.
Step 1: Prepare the Rotisserie Chicken
Remove the skin and bones from the cooled rotisserie chicken.
Dice or shred the chicken into bite-sized pieces — not too fine, not too chunky.
Place the chicken into a large bowl.
This is the cozy heart of your Homemade Costco Chicken Salad Recipe.
Step 2: Add Crunch and Freshness
Chop the celery finely (Costco uses small uniform pieces for perfect texture).
Add celery and optional diced onion to the bowl.
Already, you have the tender + crunchy balance that makes this recipe so irresistible.
Step 3: Make the Creamy Dressing
In a separate bowl whisk together:
- Mayonnaise
- Dijon mustard
- Lemon juice
- Sugar
- Salt
- Black pepper
- Garlic powder
Taste and adjust:
- More sugar = slightly sweeter like Costco
- More Dijon = more savory and tangy
- More mayo = extra creaminess
This dressing transforms your Homemade Costco Chicken Salad Recipe into the deli-style perfection you know and love.
Step 4: Combine
Pour the dressing over the chicken mixture and gently fold until everything is evenly coated.
Be careful not to mash the chicken — the best texture is creamy but still distinct.
Step 5: Chill (Optional but Amazing)
Cover and refrigerate for at least 20–30 minutes.
As it chills, the dressing absorbs into the chicken and the flavors deepen — just like the container from Costco after it sits overnight.
Step 6: Serve & Enjoy
Grab a spoon or your favorite serving bread, because your Homemade Costco Chicken Salad Recipe is ready to enjoy — creamy, savory, fresh, and comforting in every bite.
