These Mini Chicken Salad Croissants elevate the classic chicken salad to a perfect picnic-worthy treat. Tender shredded chicken mixed with crunchy celery, fresh parsley, and tangy mayonnaise creates a filling that's both satisfying and refreshing. Served on buttery mini croissants with crisp butter lettuce, they're elegant enough for special occasions yet simple enough for everyday enjoyment.
Last spring, I prepared these for a garden party and they vanished within minutes. My friend's seven-year-old daughter declared them "fancy sandwiches" and asked for seconds, while the adults praised their refreshing flavor and perfect portion size.
Essential Ingredients and Selection Tips
- Rotisserie Chicken - Save time with store-bought; Costco's are particularly flavorful
- Avocado Oil Mayonnaise - Provides tangier flavor than regular mayo
- Fresh Parsley - Don't substitute dried; fresh herbs make all the difference
- Lawry's Seasoned Salt - The secret ingredient that can't be substituted
- Mini Croissants - Look for them in the bakery section of most grocery stores
The magic happens when the seasoned chicken salad sits for a few minutes, allowing the flavors to meld together while the celery maintains its satisfying crunch.
Detailed Cooking Instructions
- Step 1:
- Prepare the Chicken Start with a fully cooled rotisserie chicken. Remove all skin and bones, then shred the meat into bite-sized pieces using two forks or your fingers. For mini croissants, slightly smaller shreds work best.
- Step 2:
- Dice the Celery Cut celery ribs in half lengthwise, then slice crosswise into small, uniform pieces about ¼-inch thick. This size gives the perfect crunch without overwhelming each bite.
- Step 3:
- Chop the Parsley Roughly chop fresh parsley, focusing on the leaves rather than stems. The fresh herb adds bright color and a subtle flavor that perfectly complements the chicken.
- Step 4:
- Mix the Filling In a large bowl, combine shredded chicken, diced celery, and chopped parsley. Add mayonnaise and Lawry's Seasoned Salt, then gently fold everything together until thoroughly combined.
- Step 5:
- Taste and Adjust Before filling the croissants, taste the chicken salad and adjust seasoning if needed. The flavors will develop more over time, so it's better to slightly under-season now.
- Step 6:
- Prepare the Croissants Slice mini croissants horizontally, leaving one side intact to create a hinge. This prevents filling from falling out when eaten.
- Step 7:
- Add the Mayo Base Spread a thin layer of mayonnaise on the inside of each croissant before adding other ingredients. This creates a moisture barrier that prevents the croissant from becoming soggy.
- Step 8:
- Layer the Lettuce Add 2-3 small leaves of butter lettuce to each croissant. Arrange them so they slightly extend beyond the edges of the bread for a pretty presentation.
- Step 9:
- Fill with Chicken Salad Spoon about 2-3 tablespoons of chicken salad onto each prepared croissant, adjusting the amount based on the size of your croissants.
- Step 10:
- Serve or Store Arrange on a serving platter immediately, or wrap individually in parchment paper if preparing for a picnic. If making ahead, keep the filling separate and assemble just before serving.

I learned the importance of that thin mayo barrier the hard way after preparing dozens of soggy sandwiches for a garden party. Now this simple step ensures perfect sandwiches every time.
Seasonal Picnic Pairings
For spring picnics, I pair these croissants with fresh strawberries and sparkling lemonade. Summer outings call for watermelon slices and iced tea. Fall picnics work beautifully with apple chips and mulled cider. Even winter indoor "picnics" feel special with these sandwiches alongside a warm soup in thermoses. Their versatility makes them perfect year-round companions for outdoor gatherings.

Make-Ahead Strategy
When planning for events, I prepare the chicken salad up to two days ahead, storing it in an airtight container. The flavor actually improves overnight as ingredients meld. For transportation, I pack components separately - chicken salad in a chilled container, washed lettuce in paper towels, and croissants in bakery bags. Assembly takes just minutes upon arrival, ensuring maximum freshness.
Elegant Presentation Ideas
For baby showers or afternoon teas, I arrange these miniature sandwiches on vintage cake stands, alternating with fresh flowers. For casual gatherings, I wrap each sandwich in parchment paper tied with twine, displaying them in a rustic basket. When serving as appetizers, I cut regular croissants into thirds after filling, securing each with a decorative pick.
Kid-Friendly Adaptations
Children sometimes hesitate with visible herbs and celery pieces. For family gatherings, I set aside a portion of finely minced chicken and mayonnaise before adding other ingredients. Mini croissants are naturally appealing to small hands, making these sandwiches perfect for introducing sophisticated flavors in approachable portions. The "fancy sandwich" appeal often overcomes typical childhood food resistance.
Chef's Essential Tips
- For extra flavor, add a teaspoon of Dijon mustard to the chicken mixture
- Toast the croissants lightly if you prefer more structure in your sandwich
- Chop ingredients to similar sizes for the perfect balanced bite
- Pat your chicken dry before mixing if it seems too moist
- For prettier presentation, garnish the platter with additional parsley sprigs
I've refined these tips through countless picnics and gatherings. The dijon addition came from a happy accident when I was low on mayonnaise and needed to stretch the mixture.

Final Tips
- Slice grapes or apples into the mixture for a sweet counterpoint to the savory chicken
- For a more substantial sandwich, add a slice of creamy brie or havarti cheese
- Keep sandwiches chilled with a frozen water bottle wrapped in a kitchen towel
- Serve with individual bags of kettle chips for a satisfying crunch contrast
- Pack extra napkins - these delicious sandwiches can be a bit messy!
These mini chicken salad croissants celebrate the simple pleasure of enjoying good food in beautiful surroundings. Whether you're planning an elaborate picnic or just a quick lunch in the backyard, they transform ordinary moments into memorable occasions through the magic of thoughtful, delicious food.
