How to Make Roasted Fingerling Potatoes Green Beans In Tarragon Sauce

  1. Preheat oven to 425°F (220°C).
  2. Cut 1 lb fingerling potatoes in half lengthwise. (If substituting, use 1 1/2 lbs small red potatoes, halved, or 1 1/2 lbs russet potatoes, quartered. Adjust baking time as needed - see recipe notes.)
  3. In a large bowl, toss potatoes with 1 tablespoon olive oil, 1/2 teaspoon salt, and 1/2 teaspoon black pepper.
  4. Place potato halves, cut sides up, in a jelly-roll pan.
  5. In a separate bowl, toss 1 lb green beans with 1/2 tablespoon olive oil, 1/2 teaspoon salt, and 1/4 teaspoon black pepper.
  6. Place green beans in another jelly-roll pan.
  7. Bake potatoes at 425°F (220°C) for 30-32 minutes, or until tender and browned.
  8. While potatoes bake, prepare the tarragon sauce (see below).
  9. **Creamy Tarragon Sauce:**
  10. In a small bowl, whisk together 1/4 cup mayonnaise, 2 tablespoons sour cream, 1 tablespoon Dijon mustard, 1 tablespoon chopped fresh tarragon, 1 tablespoon lemon juice, and 1/4 teaspoon salt.
  11. Gradually whisk in 2 tablespoons olive oil in a slow, steady stream, whisking constantly until smooth.
  12. Stir in 2 tablespoons chopped green onions.
  13. Remove potatoes from oven and let stand in the pan.
  14. Bake green beans for 12 minutes, or until tender-crisp.
  15. Arrange green beans around roasted potatoes on a serving platter.
  16. Drizzle generously with creamy tarragon dressing. Serve immediately.
  17. **Note:** If making the sauce ahead, store in an airtight container in the refrigerator for up to 2 days. Let chilled dressing stand 30 minutes before using.
