This bright and Creamy Tarragon Potato Salad is made with crème fraîche, fresh herbs, and a touch of dijon mustard for tanginess. It's not only simple to make, but perfect for spring and summer.
Slice the potatoes into ¼-inch (0.6 cm) thick rounds then add them to a medium to large pot and cover with 2 inches (5 cm) of water. Generously salt the water and bring to a boil over high heat.
Continue boiling for 8-10 minutes until the potatoes are fork tender.
Meanwhile, make the dressing by adding the crème fraîche, mayo, dijon mustard, tarragon, dill, shallot, salt, and pepper to a large bowl. Mix to combine.
Drain the potatoes into a colander and let them sit for 10 minutes to cool slightly.
Add the warm potatoes to the dressing and use a spoon to gently toss them until they're well coated. Be careful not to break the potatoes.
Let the potato salad rest at room temperature for 1 hour to let the flavors meld. Don't put them in the fridge as the sauce will not be creamy when cold.
Toss just before serving to ensure everything is still well coated then serve on a bed of arugula (optional). Top with more fresh herbs and enjoy!
Notes
Storing Leftovers: Store in an airtight container and keep in the fridge for up to 3 days. Just note that the texture will have changed and won't be as creamy. Still delicious though!
