Copycat Sam's Club Rotisserie Chicken Salad Recipe: Shredded Tender Chicken with Celery-Vinegar Gloss

This copycat Sam's Club rotisserie chicken salad delivers the same tender, juicy chicken and signature celery-vinegar dressing you love from the store—without the $12 price tag. 💛 After years of perfecting restaurant-style rotisserie chicken at home, I finally cracked the code for replicating that glossy, vinegar-kissed flavor and melt-in-your-mouth texture.

The secret lies in a two-step roasting method that keeps the chicken impossibly moist while developing that crispy skin, plus a dressing that balances sharp vinegar with just the right amount of sweetness.

The key to nailing this salad is starting with a whole chicken roasted low and slow, then finishing it under the broiler for crispy skin. Once shredded, the chicken stays juicy and tender, not dry or rubbery like many copycat versions.

The dressing—where the magic happens—combines apple cider vinegar, mayonnaise, and a touch of sugar to mimic that signature glossy finish. This isn’t just a salad; it’s a restaurant-quality meal that comes together in under an hour, with ingredients you likely already have on hand.

By the time you’re done assembling this salad, you’ll have layers of crisp romaine, perfectly seasoned chicken, crunchy celery, and that unmistakable celery-vinegar dressing clinging to every bite. It’s the kind of dish that disappears faster than the store-bought version, leaving everyone asking for seconds.

Whether you’re meal prepping for the week or hosting a lunch for a crowd, this recipe delivers professional results with a fraction of the effort.

Pro tip: For extra crispiness, broil the chicken for just 2-3 minutes at the end—this creates that satisfying snap you get from the store version. The dressing can be made ahead and stored in the fridge for up to 5 days, so you can assemble the salad whenever you’re ready.

Let’s get started on recreating this fan-favorite dish at home.

Ingredients for copycat sam's club rotisserie chicken salad

Six ingredients for the chicken, five for the dressing—simple stuff for restaurant-quality flavor.

The chicken is everything here. Whole chicken (3-4 lbs) is best—boneless breasts get dry. Costco or Walmart usually have them at great prices, especially in the fall. Look for bright red skin and firm flesh. The butter and olive oil combo keeps it juicy while the broiler gives that crispy skin. I always season mine with salt, pepper, and thyme—skip the paprika, it’s not in the store version. For extra crispiness, broil for just 2-3 minutes at the end (trust me on this).

No apple cider vinegar? White vinegar or red wine vinegar works in a pinch, but the apple cider’s sweetness is key. The mayonnaise matters—Duke’s or Hellmann’s are the closest to the store version. The sugar? It’s not just for sweetness—it helps the dressing cling to the chicken. Celery and onion can be swapped for green onions or radishes if you’re feeling fancy. The dressing keeps for 5 days in the fridge, so make extra—you’ll want it.

Romaine stays crisp for 3 days if you wrap the head tightly in a damp towel. The shredded chicken? 4 days in the fridge, or freeze for 3 months. I portion mine into containers with dressing on the side—lunches are ready in seconds. The dressing thickens when chilled, so give it a quick whisk before using. This salad tastes even better the next day once everything melds.

Step-by-step instructions for sam's club rotisserie chicken salad

Here's how to recreate that signature tender chicken with that signature celery-vinegar dressing.

Preheat your oven to 375°F. Pat the 4 lb whole chicken completely dry with paper towels—this helps the skin crisp up. Rub the cavity with 1 tsp dried thyme, 2 tsp salt, and 1 tsp black pepper, then stuff it with the remaining 1 medium red onion and 3 whole celery stalks (cut into chunks). Tie the legs together with kitchen twine and place the chicken on a rack in a roasting pan.

Drizzle 0.5 cup extra-virgin olive oil evenly over the skin and rub it in with your hands. Roast for 1 hour 15 minutes until the internal temperature reaches 165°F and the juices run clear. Here's the thing—don't open the oven door until then. Every peek lets heat escape and steams the skin instead of crisping it.

Transfer the chicken to a cutting board and let it rest for 10 minutes before handling. Remove the twine and discard the onion and celery from the cavity. Using two forks, shred the chicken into 1-inch pieces, discarding any skin or large fat chunks. You should have about 4 cups of shredded chicken—this is your base.

In a small bowl, whisk together 0.33 cup apple cider vinegar, 2 tbsp granulated sugar, 4 minced garlic cloves, 1 tbsp lemon juice, 1 tsp black pepper, and 1 tsp salt. Let this sit for 5 minutes to allow the sugar to dissolve and the flavors to meld. This is the secret to that tangy-sweet dressing that makes this salad so addictive.

Chop the 1 head romaine lettuce into ½-inch pieces and place in a large bowl. Add the shredded chicken and toss gently to combine. In a separate small bowl, mix 0.5 cup mayonnaise with the vinegar mixture you prepared earlier. Drizzle this over the chicken and lettuce, tossing until everything is evenly coated.

For the final touch, finely dice the remaining 1 medium red onion and 3 whole celery stalks (about ¼ cup each) and fold them into the salad. The celery adds that signature crunch and freshness that balances the richness of the chicken and mayo. Taste and adjust seasoning if needed—you might want a little more salt or vinegar, depending on your preference.

Cover the salad and refrigerate for at least 1 hour before serving. This chilling time lets the flavors meld together perfectly. The chicken will absorb the dressing, becoming even more tender and juicy. If you're short on time, let it sit for at least 30 minutes—it's still delicious, but the longer it chills, the better it tastes.

Serve the salad on a platter or in individual bowls, garnished with extra diced celery and red onion if desired. The contrast of the crisp vegetables against the tender, flavorful chicken is what makes this salad so special. Store any leftovers in an airtight container in the refrigerator for up to 3 days, though I doubt it'll last that long!

Dietary considerations for this recipe

Gluten-Free Adaptation

This salad is naturally gluten-free, but there are a few precautions to take. First, check your mayonnaise—many brands contain gluten as a stabilizer. I recommend Hellmann’s Gluten-Free or Duke’s Gluten-Free to stay safe.

Also, verify that your dried thyme and salt are certified gluten-free, as some blends contain cross-contamination. The romaine, celery, and red onion are all gluten-free vegetables, so no substitutions are needed there. 🌱

Dairy-Free Options

For a dairy-free version, replace the mayonnaise with a vegan alternative like Just Mayo or Sir Kensington’s Vegan Mayo. These brands mimic the creamy texture while keeping the dressing cohesive.

The celery-vinegar base remains the same, so the tangy flavor stays intact. Just be sure to check the labels on any store-bought dressings or mayo substitutes for hidden dairy ingredients.

Lower-Carb Adjustments

To reduce carbs, skip the romaine lettuce and use butter lettuce or iceberg lettuce instead—they have fewer carbs per cup. You can also omit the red onion if you're watching carbs, but I’d recommend keeping it for that signature crunch and flavor.

The chicken and celery are already low-carb, so the biggest adjustment is in the greens. For extra protein, consider adding hard-boiled eggs or avocado slices on top.

Protein Boost

This salad is already packed with protein from the chicken, but you can easily boost it further. Add ½ cup cooked quinoa per serving for extra plant-based protein, or mix in ½ cup chickpeas for a heartier texture.

For a meat lover’s twist, fold in ¼ cup crumbled bacon or ¼ cup diced ham**. Both additions will add depth and extra protein without overpowering the dish. 💪
