Preheat your oven to 400°F (200°C).
Toss the halved baby potatoes with olive oil, salt, and pepper until they are evenly coated.
Spread the potatoes in a single layer on a baking sheet and roast for 25-30 minutes, or until golden brown and crispy, turning halfway through the cooking time.
While the potatoes are roasting, combine the white wine vinegar, dry white wine, and minced shallots in a small saucepan over medium heat. Simmer until the liquid is reduced to about 2 tablespoons.
In a heatproof bowl, whisk together the egg yolks, water, and lemon juice. Then, place the bowl over a pot of simmering water (double boiler) and continue to whisk until the mixture is thickened and doubled in volume.
Remove the bowl from the heat and slowly drizzle in the melted butter, whisking constantly until the sauce is thickened and emulsified.
Stir in the reduced vinegar mixture and chopped tarragon into the sauce. Season with salt and pepper to taste.
Once the potatoes are roasted, remove them from the oven and transfer to a serving dish.
Spoon the Béarnaise sauce over the roasted potatoes just before serving.
