Hot Potato & Broccoli Salad

This is the picnic potato salad for people who don’t trust mayonnaise on a hot day. A warm vinaigrette of lemon juice, oil, and basil gets poured over hot diced potatoes and just-cooked broccoli, so the vegetables drink up the dressing while still warm. Serve hot, room temperature, or chilled, all three are correct.

The trick of dressing the vegetables while they’re hot is borrowed from German potato salad. Hot starchy potatoes act like sponges, soaking up the lemon-oil dressing all the way through instead of just on the surface. Cold potatoes barely absorb anything; that’s why mayo-based salads taste like dressing on top of bland cubes.

Bringing the dressing to a boil first might seem fussy but it’s intentional. The brief boil mellows the raw lemon juice’s sharp edge and bonds the seasonings into one cohesive flavor instead of just being oil and lemon sitting next to each other.

A few drops of hot pepper sauce is the small detail that lifts this above standard potluck fare. You won’t taste heat, just a low warmth that makes the whole salad more interesting.

Kitchen Tips

• Use waxy potatoes (Yukon Gold or red potatoes) so they hold their shape when diced. Russets fall apart.
• Don’t overcook the broccoli, you want bright green and just-tender, not army drab.
• Slice scallions on a sharp diagonal for visual appeal and stronger flavor.
• Make ahead: this salad is even better after a few hours in the fridge.

Variations

• Add halved cherry tomatoes and crumbled feta for a Greek-style version.
• Stir in a tablespoon of grainy mustard along with the lemon for sharper flavor.
• Top with toasted pine nuts and a handful of fresh basil leaves just before serving.
