Roasting potatoes is the ultimate way to avoid watery, mushy or bland potato salad. Boiled potatoes can hold on to moisture (even if they seem dry!), which can affect the texture of the final dish. Roasted potatoes hold their shape without the risk of them falling apart, and the roasting process concentrates the flavor of the potatoes so your potato salad will be extra savory. We love the anise flavor of tarragon in the dressing but feel free to use a mix of fresh herbs to make this easy side dish your own.
