Creamy Tarragon Chicken Salad

Tarragon is the reason this chicken salad tastes restaurant rather than rotisserie-leftover. That subtle anise-licorice note plays off red grapes and toasted walnuts in a way plain chicken salad cannot touch.

Poaching the chicken breasts in broth in a hot oven is the move that keeps them tender. The surrounding liquid steams the meat at a steady pace so nothing dries out. Pull at 170°F (77°C) internal temperature, let it rest, then cube once cool enough to handle.

A 50/50 mix of sour cream and mayonnaise makes the dressing lighter than straight mayo while still creamy enough to coat. Sweet red grapes, crunchy celery, and those toasted walnuts give every forkful three distinct textures.

An hour in the fridge is key. The dried tarragon needs time to hydrate and bloom in the cold dressing; skip the chill and the flavor stays flat.

Kitchen Tips

• Toast the walnuts even though it’s an extra step. Raw walnuts taste flat; toasted ones bring out a buttery depth.
• Cube the chicken uniformly, about ½ inch. Giant chunks don’t absorb dressing evenly.
• Use dried tarragon, not fresh, for this cold salad. Fresh tarragon wilts and bruises; dried blooms in the dressing.
• Halve the grapes rather than leaving whole so sweetness spreads through every bite.

Variations

• Swap walnuts for toasted pecans, almonds, or pine nuts.
• Use Greek yogurt in place of sour cream for more tang and protein.
• Add chopped fresh apples, dried cranberries, or a squeeze of lemon juice for brightness.
