Chicken Salad Recipe for Large Group: No-Fuss Picnic Perfection With Crunchy Celery Crowns

This chicken salad recipe for large groups transforms a picnic from ordinary to extraordinary—10 pounds of chicken shredded to tender perfection, crowned with crisp celery and bound in creamy dressing that stays fresh for hours. 💛 I developed this after hosting a backyard gathering where store-bought chicken salad fell apart by the third plate.

The secret? Chilling the mixture for at least 2 hours before serving ensures the celery stays crisp and the texture remains ideal.

What sets this recipe apart is its scalability—double or triple the ingredients without sacrificing flavor. Use two large mixing bowls for efficient prep, and let the salad sit uncovered in the fridge to develop deeper flavors.

The celery crowns add a satisfying crunch that disappears within minutes of serving, making it a crowd-pleaser every time. This isn't just chicken salad; it's a picnic game-changer that keeps guests reaching for seconds.

By the time you're ready to serve, you'll have a dish that's restaurant-quality but made in your own kitchen. The chicken stays juicy, the celery maintains its snap, and the dressing binds everything together without overpowering the natural flavors.

It's the kind of recipe that makes you look like a pro—even when you're feeding 20 people for the first time.

Serve this chicken salad on crostini, stuffed into sandwiches, or straight from a large bowl with crackers. It keeps well for up to 3 days in the fridge, making it perfect for meal prep or last-minute gatherings. Here's how to make it foolproof for your next event.

Ingredients for chicken salad recipe for large group

Ten pounds of chicken, crisp celery crowns, and a creamy dressing that stays fresh for hours—this is picnic perfection scaled up.

The chicken is the star, so choose high-quality breasts—look for plump, pale meat with good marbling. I always buy Costco's family pack for large groups—it's pre-cooked and ready to shred. For the celery crowns, organic bunches from Trader Joe's work best—they're crisp and last longer. The red onion should be firm and white, not soft or sprouting. If you're prepping ahead, store the shredded chicken in the fridge for up to 3 days—it actually tastes better the next day as the flavors meld.

No full-fat mayo? Greek yogurt mixed with a little olive oil works perfectly—just add an extra tablespoon of lemon juice to balance. Fresh dill and chives can be swapped for dried at one-third the amount, but honestly, they're worth hunting down for the fresh flavor. The apple cider vinegar adds a subtle tang that cuts through the richness—substitute lemon juice if that's what you've got. For the celery crowns, thinly slice the stalks and toss them in ice water for 10 minutes before adding to the salad to keep them extra crisp. If you're making this ahead, chill the mixture uncovered for 2 hours before serving—it develops deeper flavor and lets the celery stay crunchy.

This salad keeps beautifully for 3 days in the fridge, making it perfect for meal prep. Store the dressing separately if you're prepping more than a day ahead—combine just before serving for the best texture. For serving, I use large glass bowls with wooden spoons—it looks stunning and makes it easy to serve. The celery crowns disappear fast, so double the amount if you're serving a big crowd. Freezes well for 2 months if you want to make it even further ahead, though the celery may soften slightly after thawing.

Step-by-step instructions for large group chicken salad

Here's how to assemble this crowd-pleasing chicken salad with perfect texture and flavor.

Start by shredding the 10 lb cooked chicken breast into bite-sized pieces. I like to use two forks—grab one forkful of chicken and pull it apart against another fork's tines. This gives you nice, even shreds instead of uneven chunks. Work in batches if needed to keep the chicken warm and manageable.

As you shred, transfer the chicken to a very large mixing bowl—this will be your main workspace. The bowl needs to be big enough to handle all ingredients without overflowing. If you're using cold chicken, let it sit at room temperature for 10-15 minutes first to make shredding easier and prevent a cold salad.

In a separate medium bowl, whisk together the 3 cups mayonnaise, 1.5 cups Greek yogurt, 0.5 cup lemon juice, 2 tbsp Dijon mustard, 1 tbsp apple cider vinegar, and 1 tbsp granulated sugar. Mix until smooth and fully combined—this creates your creamy foundation. The yogurt adds tanginess while keeping the texture lighter than mayo alone.

Taste the mixture and adjust seasoning if needed. You might need an extra pinch of salt or a squeeze of lemon depending on your mayo's saltiness. This is your flavor baseline before adding other ingredients. Keep this mixture at room temperature while you prepare the remaining components.

For the crunchy celery crowns, trim the 2 bunch celery stalks by cutting off the leafy tops and bottoms. Then, slice each stalk lengthwise into ¼-inch thick half-moons—this creates those classic celery crown shapes. Place them on a baking sheet and set aside.

Next, peel and thinly slice the 3 whole red onions into ⅛-inch rings. The thinner you slice, the more delicate they'll be when mixed in. Don't skip this step—the onion adds sweetness and crunch that balances the richness of the chicken and mayo.

Add the wet ingredient mixture to the shredded chicken in your large bowl. Gently fold everything together using a large spatula or wooden spoon. Don't overmix—just combine until evenly distributed. The chicken should be fully coated in the creamy dressing.

Now stir in the 0.25 cup chopped fresh dill, 0.25 cup chopped fresh chives, 1.5 tsp salt, and 1 tsp black pepper. The herbs add freshness while the seasonings tie all the flavors together. Taste again and make any final adjustments—this is your quality control moment before serving.

Just before serving, fold in the celery crowns and onion rings. Adding them last preserves their crisp texture—if mixed in too early, they'll soften in the mayo. For a picnic setting, I recommend keeping the celery and onions separate until serving to maintain maximum crunch.

Let the salad sit for 10-15 minutes at room temperature before serving. This allows all the flavors to meld together beautifully. For large groups, divide the salad into serving bowls and garnish each with extra fresh chives and a sprinkle of black pepper. Serve immediately with crusty bread or crackers for the perfect picnic spread.

Pro cooking tips for chicken salad recipe for large group

Large-Batch Shredding

For 10 lbs of chicken, use two forks to shred efficiently—grab one forkful and pull against another fork's tines. Work in batches to keep the chicken warm and prevent sogginess. I swear by this method over knives, which create uneven chunks.

Keep the shredded chicken in a very large mixing bowl—I use a 12-quart stainless steel bowl from my grandmother's kitchen. 💛

Dressing Prep Shortcut

Make the creamy base first by whisking 3 cups mayonnaise, 1.5 cups Greek yogurt, and seasonings in a separate bowl. This keeps your workspace organized and prevents mayo splatters when mixing.

I always taste the dressing before adding it to the chicken—adjust salt or lemon juice as needed. The yogurt adds tanginess that cuts through the richness.

Celery Crown Hack

Slice celery into ¼-inch thick half-moons and soak in ice water for 10 minutes before adding to the salad. This keeps them crisp for hours, even when mixed with mayo.

I double the amount for large groups—they disappear faster than you'd think! For extra crunch, add a pinch of salt to the ice water before soaking.

Room-Temp Secret

Let the salad sit at room temperature for 10-15 minutes before serving. This allows flavors to meld beautifully—especially important for large batches. I place the bowl on the counter while I set the table.

The celery stays crisp while the chicken and dressing develop deeper flavor. Trust me, this small step makes a huge difference. ⏰

Serving Strategy

For picnics, divide the salad into individual bowls just before serving. This keeps the celery and onions fresh until each guest gets their portion. I garnish each bowl with extra chives and black pepper right before serving—it looks stunning and makes everyone feel special.

Use wooden spoons for serving to maintain that restaurant-quality presentation.

Make-Ahead Magic

This salad keeps perfectly for 3 days in the fridge, making it ideal for meal prep. Store the dressing separately if prepping more than a day ahead—combine just before serving for the best texture.

For freezing, package in airtight containers without the celery crowns (add them fresh after thawing). The flavors actually improve overnight as everything melds together. 💡
