A Classic Chicken Salad Sandwich with Mayo

This Classic Chicken Salad Sandwich with Mayo is the version that earns the word classic — creamy, perfectly seasoned, with enough texture from celery and onion to make each bite interesting without distracting from the chicken itself. It’s the sandwich that disappears first at every lunch spread, potluck, and picnic table for a reason that has nothing to do with novelty and everything to do with getting the fundamentals exactly right.

The difference between a chicken salad that tastes flat and one that tastes like it came from a good deli counter comes down to three things: using poached rather than roasted chicken for a more tender, evenly seasoned result; the ratio of mayonnaise to chicken, which should coat generously without turning the filling into a paste; and a small amount of acid — lemon juice or a splash of white wine vinegar — that most home recipes skip but every great version includes.

Make it at least an hour ahead of serving, ideally the morning of or the night before — the flavour improves significantly as the chicken absorbs the seasoned dressing and the whole mixture settles into something cohesive.

Why This Version Beats Every Shortcut Version

Poaching the chicken directly in seasoned water takes 20 minutes and produces a consistently moist, tender result that pre-cooked rotisserie chicken rarely matches for texture — rotisserie chicken adds a smoky, roasted flavour that competes with the delicate mayo dressing rather than working with it.

The small additions that seem optional — the Dijon, the lemon juice, the pinch of celery salt — are what separate a sandwich filling that tastes like something from a gas station deli from one that tastes intentional and complete.

• Prep Time: 10 minutes
• Cook Time: 20 minutes (poaching)
• Chill Time: 30 minutes minimum
• Total Time: 1 hour
• Yield: 4 generous sandwiches

What Goes Into It

For the poached chicken:

• Boneless, skinless chicken breasts: 1.5 lbs (680g)
• Cold water: enough to cover the chicken by 1 inch
• Bay leaf: 1
• Whole black peppercorns: 6
• Garlic clove, smashed: 1
• Fine sea salt: 1 teaspoon

For the chicken salad filling:

• Poached chicken, cooled and diced or hand-shredded: all of the above
• Good quality mayonnaise: 1/2 cup (110g)
• Celery, finely diced: 3 stalks
• Red onion or green onion, finely diced: 3 tablespoons
• Dijon mustard: 1 teaspoon
• Fresh lemon juice: 1 tablespoon
• Celery salt: 1/4 teaspoon
• Garlic powder: 1/4 teaspoon
• Fine sea salt: 1/2 teaspoon, plus more to taste
• Black pepper: 1/4 teaspoon, freshly ground
• Fresh dill or flat-leaf parsley, chopped: 2 tablespoons (optional but recommended)

For the sandwiches:

• Bread of your choice: 8 slices (thick white sandwich bread, sourdough, or croissants for a deli-style result)
• Butter or extra mayonnaise: for spreading on the bread
• Iceberg or butter lettuce: 4 leaves
• Ripe tomato, sliced: 1 large

How to Make It From Poach to Plate

Poaching the chicken:

1. Place the chicken breasts in a single layer in a medium saucepan and cover with cold water by at least 1 inch — starting from cold rather than adding chicken to boiling water cooks it more evenly and prevents the outside from seizing before the center is done.
2. Add the bay leaf, peppercorns, smashed garlic, and salt to the water.
3. Bring to a gentle simmer over medium heat — not a rolling boil, which toughens the protein — then reduce to a bare simmer and cook for 15 to 18 minutes until the chicken is cooked through with no pink remaining.
4. Remove the chicken from the poaching liquid and let it cool on a cutting board for 10 minutes before handling — cutting into hot chicken causes the juices to run out immediately rather than redistributing into the meat.

Making the chicken salad:

1. Dice the cooled chicken into 1/2-inch pieces, or hand-shred it into irregular pieces for a more rustic texture — both approaches work, and the choice comes down to preference.
2. Combine the diced chicken, celery, and onion in a large bowl.
3. Whisk the mayonnaise, Dijon mustard, lemon juice, celery salt, garlic powder, salt, and pepper together in a small bowl until smooth.
4. Pour the dressing over the chicken mixture and fold gently until everything is evenly coated — do not stir aggressively or the chicken will break down into strings.
5. Fold in the fresh herbs if using.
6. Taste carefully and adjust — more salt if it tastes flat, more lemon juice if it needs brightness, more mayonnaise if it seems dry.
7. Cover and refrigerate for at least 30 minutes, or up to overnight, before assembling the sandwiches.

Assembling the sandwiches:

1. Toast the bread lightly if using sandwich bread — toasting adds structural integrity that prevents the bread from going soggy under the filling.
2. Spread butter or a thin layer of extra mayonnaise on each slice of bread.
3. Place a lettuce leaf on the bottom slice, then spoon a generous mound of chicken salad over it.
4. Add a slice or two of tomato, season lightly with salt and pepper, and close the sandwich.
5. Cut diagonally for serving — the diagonal cut exposes more of the filling on the cut face and makes the sandwich easier to handle.

The Technique Details That Make This Better Than Average

Starting the chicken in cold water rather than dropping it into boiling water is the single most impactful technique change for consistently moist, evenly cooked chicken. Hot water causes the exterior proteins to contract and set immediately while the center is still raw, creating a gradient of done-to-overdone from outside to inside. Cold water allows the chicken to warm gradually and cook more evenly throughout. According to Serious Eats, the cold-water poaching method produces measurably more tender, juicy chicken than the boiling method because the gentler, more gradual heat rise keeps the proteins from seizing too quickly.

Tasting and seasoning after the salad has rested is more important here than in almost any other recipe in this collection — the flavours absorb and meld during the chill time, and a filling that tastes slightly under-seasoned when first mixed often tastes just right after 30 minutes in the fridge. Taste it after the rest before adding more salt.

The ratio of mayonnaise to chicken matters more than the brand — too little and the filling is dry and crumbly, too much and it turns into a paste that overwhelms every other flavour. The right amount coats every piece of chicken visibly but leaves no pool of dressing at the bottom of the bowl when you scoop it.

What to Serve Alongside

Classic accompaniments that actually work: a handful of kettle chips for salt and crunch, a small dill pickle on the side, or a light green salad with vinaigrette to contrast the creaminess of the mayo filling.

For a full lunch spread that goes beyond one sandwich, our Paula Deen Tuna Fish Salad makes a natural companion offering — set both out with a selection of breads and crackers and you have a deli-style lunch spread that requires no hot food and assembles in minutes.

Variations Worth Making More Than Once

Add 1/3 cup of halved seedless red grapes and 1/4 cup of toasted pecans for the Waldorf-adjacent direction that turns a simple filling into something more substantial and dinner-party appropriate.

Stir in 1 tablespoon of sweet relish and reduce the lemon juice to 1 teaspoon for a Southern-style version that’s sweeter and more familiar in a comfort-food direction — serve it on soft white bread for the full effect.

Replace half the mayonnaise with full-fat Greek yogurt for a lighter, tangier version with noticeably more protein — the texture is slightly less rich but still cohesive, and the tang from the yogurt plays well with the Dijon and lemon.

Serve the chicken salad on a croissant instead of sandwich bread for an immediate upgrade in presentation and flavour — the buttery, flaky pastry is the format that makes this feel like something you’d pay twelve dollars for at a good lunch spot.

If you love the Dijon-lemon-herb direction of this filling, our California Roll Cucumber Salad uses a similarly bright, acidic dressing profile in a completely different format and makes a refreshing side for the same lunch table.

These values are estimates based on standard white sandwich bread, full-fat mayonnaise, and standard chicken breast, divided by 4 sandwiches. Serving the filling on a croissant adds approximately 200 calories and 12 grams of fat per sandwich. Substituting Greek yogurt for half the mayo reduces the fat to approximately 15 grams per sandwich.

Storing the Filling and Making It Ahead

The chicken salad filling — without the bread — keeps in an airtight container in the fridge for up to 3 days. The flavour is best on day one and two before the celery begins to soften noticeably and the dressing starts to thin from the vegetable moisture released over time.

Do not assemble the sandwiches ahead of time if they’re traveling to a picnic or potluck — the bread goes soggy within 20 to 30 minutes of contact with the filling, especially with tomato added. Carry the filling and bread separately and assemble on site.

The chicken itself can be poached up to 2 days ahead and stored in the poaching liquid in the fridge — keeping it submerged in the liquid preserves moisture better than storing the meat dry. Drain and dice when you’re ready to make the filling.

What Goes Wrong and Why

Overcooking the chicken during poaching is the most common issue and the hardest to fix — overcooked chicken breast shreds into dry, fibrous strings no amount of mayonnaise can fully rescue. A bare simmer rather than a boil and pulling the chicken at the first sign of no remaining pink is the difference. If in doubt, use an instant-read thermometer and pull at exactly 165°F (74°C).

Under-seasoning the filling before it rests is extremely common because the flavours taste muted right after mixing — the salt, acid, and herb flavours need at least 30 minutes to absorb into the chicken. Mix conservatively, rest, taste again, and adjust only if it still tastes flat after the rest period.

Using low-quality or light mayonnaise is the shortcut that most noticeably affects the result — the filling will taste thinner and less rich, and the texture won’t coat the chicken as evenly. Full-fat mayonnaise is worth using here since it’s the primary flavour vehicle in the entire filling.
