Salads
Hosting a picnic for 50 demands chicken salad sandwiches that stay fresh, hold up to handling, and deliver that perfect crunch in every bite.
I developed this recipe after years of perfecting large-batch chicken salad—where the secret lies in properly cooked, seasoned chicken and a binder that keeps everything cohesive without turning mushy. The key?
A precise ratio of mayo to Greek yogurt, finely chopped celery and herbs, and a bread choice that can handle crowd-sized assembly.
This recipe starts with 8 pounds of boneless, skinless chicken breasts, poached just until tender and shredded into bite-sized pieces.
The salad mix includes 3 cups of finely diced celery, 1 cup of chopped fresh parsley, and 1 cup of diced red grapes for natural sweetness—all tossed in a creamy base of 5 cups of mayonnaise and 3 cups of Greek yogurt to ensure moisture without heaviness.
For the sandwiches, I recommend using 100 whole wheat or sourdough hoagie rolls, lightly toasted to prevent sogginess.
What you’ll achieve is a batch of sandwiches that stay intact when stacked, resist wilting in the sun, and deliver that satisfying crunch from the celery and grapes. The chicken stays juicy, the bread holds its shape, and the flavors remain vibrant even after hours.
This is the kind of recipe that turns a simple picnic into a memorable event—without the stress of last-minute prep.
Prep ahead by assembling the chicken salad the night before and refrigerating it, then build the sandwiches just before serving. For extra efficiency, use a sandwich press to ensure uniform size and presentation. This method scales perfectly for 50 servings while keeping the quality of a homemade meal.
Ingredients for chicken salad sandwich recipe for 50
Fifty servings require precise measurements and quality ingredients for perfect picnic chicken salad sandwiches.
| Ingredient | Amount | Notes |
|---|---|---|
| Boneless, Skinless Chicken Breasts 🍗 | 8 lb | Poached until tender, shredded |
| Mayonnaise 🥫 | 5 cups | High-quality, stable for large batches |
| Plain Greek Yogurt 🥛 | 3 cups | Full-fat for creaminess, non-fat for lighter texture |
| Celery Stems 🧅 | 3 cups | Finely diced, crisp variety preferred |
| Fresh Parsley 🌿 | 1 cup | Chopped, flat-leaf preferred |
| Red Seedless Grapes 🍇 | 1 cup | Diced, adds natural sweetness |
| Lemon Juice 🍋 | ½ cup | Freshly squeezed, brightens flavors |
| Diamond Crystal Kosher Salt 🧂 | 2 tsp | Adjust to taste, don't over-salt |
| Freshly Ground Black Pepper 🌶️ | 1 tsp | Freshly cracked for optimal flavor |
| Whole Wheat Hoagie Rolls 🍞 | 100 whole | Lightly toasted to prevent sogginess |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For poaching chicken, high-quality preferred |
| Garlic Cloves 🧄 | 6 cloves | Minced, enhances chicken flavor |
| Dried Dill 🌿 | 1 tbsp | Or 2 tbsp fresh dill if available |
| Unsalted Butter 🧈 | 1 tbsp | For toasting rolls, softened |
The chicken is the foundation—8 pounds of boneless, skinless breasts ensures ample protein without excess fat. Costco or local butcher shops often carry large packs of chicken breasts, or buy two 4-pound packages from Trader Joe's for convenience. For poaching, use extra-virgin olive oil and minced garlic to infuse flavor. The key is poaching just until the chicken reaches 165°F internally—overcooking dries it out. Shred immediately after cooking to maintain moisture, and let it cool before mixing with other ingredients. The Greek yogurt is non-negotiable here; it provides structure without heaviness, and full-fat Fage or Siggi's brands deliver the best texture.
No fresh parsley? Dried parsley at one-third the amount works in a pinch, though fresh is ideal for vibrant color. The grapes add natural sweetness, but if you prefer tartness, swap in diced apples or pears. For the mayo, Hellmann's or Duke's are stable for large batches, but avoid store-brand mayos that separate. The celery should be crisp—crunchy varieties like Utah celery hold up best. If you're making this ahead, store the salad mixture in airtight containers and assemble sandwiches just before serving to maintain crunch. The whole wheat hoagie rolls from Bimbo or Sara Lee are reliable for crowd sizes, but sourdough rolls add a gourmet touch if you're willing to invest in a bulk order.
The chicken salad mixture keeps well for 3-4 days in the fridge, but the rolls should be toasted fresh to prevent sogginess. For large gatherings, portion the salad into 50 individual containers and assemble sandwiches on-site. The sandwich press is a game-changer for uniform presentation—Cuisinart or Oster models are ideal for bulk prep. If you're worried about wilting, lightly butter the inside of the rolls before assembling. Leftovers can be refrigerated for 2 days, but the texture degrades after that—best enjoyed fresh.

Step-by-step instructions for perfectly balanced chicken salad sandwiches
This method ensures tender chicken, creamy texture, and picnic-proof structure for 50 servings.
Poach the Chicken to Perfect Tenderness
Fill a large stockpot with 8 quarts water and bring to a rolling boil. Add the 8 lb boneless, skinless chicken breasts, the 6 cloves garlic, and the 1 tbsp dried dill. Reduce heat to maintain a gentle simmer and cook for 12-15 minutes until the chicken reaches an internal temperature of 165°F and is fork-tender.
Real talk: Don't cut into the chicken too early—it should pull apart easily with minimal resistance. Once done, transfer the chicken to a colander and rinse under cold water for 2 minutes to stop the cooking process and remove any surface dill. This cooling step also makes shredding much easier.
Shred and Combine the Chicken with Wet Ingredients
Using two forks or your hands, shred the cooled chicken into ¼-inch thick strands. In a very large mixing bowl, combine the shredded chicken with the 5 cups mayonnaise and 3 cups plain Greek yogurt. Mix thoroughly until fully incorporated, breaking up any large chicken clumps. The mixture should be smooth and creamy with no visible lumps.
Here's where it gets fun—taste and adjust seasoning. Add the 0.5 cup lemon juice, 2 tsp Diamond Crystal kosher salt, and 1 tsp freshly ground black pepper, mixing well after each addition. The acidity from the lemon brightens the flavors while the yogurt adds a subtle tang that balances the richness of the mayonnaise.
Fold in the Crunchy and Sweet Add-Ins
Add the 3 cups finely diced celery stems, 1 cup chopped fresh parsley, and 1 cup diced red seedless grapes to the chicken mixture. Gently fold these ingredients using a large spatula, being careful not to overmix. You want the celery and grapes to remain in distinct pieces rather than becoming mushy.
This is the moment that matters: The celery adds fresh crunch, the grapes provide natural sweetness, and the parsley brings bright, herbal notes. Don't skip this step—these ingredients prevent the chicken salad from becoming too heavy. If you're making this ahead, cover and refrigerate for up to 4 hours before assembling sandwiches to let flavors meld.
Toast and Assemble the Hoagie Rolls
Lightly butter one side of each whole wheat hoagie roll using the 1 tbsp unsalted butter, spreading it evenly. In a large skillet over medium heat, toast the buttered sides for 1-2 minutes until golden brown. This step creates a barrier that prevents the rolls from becoming soggy when filled with the moist chicken salad.
I know it seems like too much butter, but trust me—this thin layer makes all the difference. Keep the toasted rolls warm in a 200°F oven while you fill them. The residual heat maintains their crispness until serving time. For extra picnic-proofing, wrap each filled sandwich in parchment paper before packing.
Fill and Serve with Picnic-Proof Precision
Using a large spoon, mound approximately ½ cup of the chicken salad onto the buttered side of each hoagie roll. Gently press down to create an even layer, then fold the roll in half to encase the filling completely. For extra security, use a toothpick to secure the sandwich if you're packing for a picnic or potluck.
Serve immediately for the freshest texture, or store filled sandwiches in an airtight container in the refrigerator for up to 24 hours. The combination of toasted rolls, creamy chicken, and crunchy vegetables creates a perfect balance of textures and flavors that holds up beautifully for gatherings. Each bite delivers that picnic-perfect crunch you're after.
Pro Tips For Making Chicken Salad Sandwich Recipe For 50
- COOK CHICKEN TO 165°F: I used to pull chicken off the heat at 160°F—just shy of the safe zone—and wondered why my salad tasted dry. Now I hit 165°F and let it rest 10 minutes before shredding. The meat stays juicy, and the salad doesn’t turn to sawdust after mixing.
- CHOP CELERY IN 1-INCH PIECES: Fine dice looks fancy, but big chunks (about 1-inch) hold their crunch longer. I learned this the hard way after serving mushy celery at a picnic—now I prep it last and add it right before serving.
- MIX YOGURT AND MAYO FIRST: Dumping all the mayo into Greek yogurt? You’ll end up with a lumpy mess. Instead, whisk half the mayo into the yogurt first, then add the rest. The texture stays smooth, and the tang doesn’t overpower the chicken.
- SALT THE CHICKEN BEFORE COOKING: Skip salting after cooking—it won’t penetrate. Wet the chicken, sprinkle 1 tsp salt per pound, and let it sit 10 minutes before cooking. The seasoning sticks, and the flavor is even throughout every bite.

Frequently asked questions
Can I use rotisserie chicken instead of poached chicken for 50 sandwiches?
Rotisserie chicken works perfectly for this recipe. Just shred 8 pounds of cooked chicken (about 3-4 large rotisserie chickens) and follow the same mixing instructions. The key is to remove any excess skin or fat before shredding to maintain a clean, creamy texture. Rotisserie chicken adds a subtle smoky flavor that pairs beautifully with the fresh herbs and grapes.
How do I keep the sandwiches from getting soggy when packing for a picnic?
Toast the rolls lightly before assembling and use the butter trick I mentioned—spread a thin layer on the bread's inner side. Wrap each sandwich individually in parchment paper or beeswax wraps, then place them in an airtight container with a layer of parchment between stacks. Keep them refrigerated until serving time to maintain crispness.
Can I make this chicken salad ahead of time and still get good crunch?
Yes, but with a few key steps. Prepare the chicken salad mixture up to 24 hours ahead and refrigerate in an airtight container. When ready to assemble, fold in the celery and grapes just before making sandwiches to preserve their crunch. For extra freshness, chill the assembled sandwiches in the fridge for 1-2 hours before serving to let flavors meld.
What's the best way to scale this recipe down for a smaller group?
For a smaller batch, reduce all ingredients proportionally. A good starting point is 2 pounds of chicken, 1 cup of mayo, ¾ cup of Greek yogurt, and ½ cup of celery for about 8 sandwiches. Use 16 rolls total. The same techniques apply—just maintain the same ratios of wet to dry ingredients for perfect texture.
How do I handle dietary restrictions like gluten-free or dairy-free?
For gluten-free, use gluten-free hoagie rolls and ensure your mayo and yogurt are certified GF. For dairy-free, substitute the Greek yogurt with dairy-free yogurt or extra mayo (use 6 cups total). Keep the celery and grapes for natural crunch—just omit any butter used for toasting rolls. The flavor profile will still shine through!
