Haricots Verts And Potatoes With Pesto Recipes

Steps:

• Whisk together vinegar, mustard, pepper, sugar, and 1 teaspoon salt in a small bowl. Add oil in a slow stream, whisking until emulsified.
• Quarter potatoes, then cover with cold water by 1 inch in a 4- to 5-quart pot and bring to a boil with remaining teaspoon salt. Reduce heat and simmer, uncovered, until potatoes are tender, 8 to 10 minutes. Drain, then transfer hot potatoes to a large bowl and toss with onion and all but 1/4 cup vinaigrette. Cool to room temperature, about 1 hour.
• While potatoes cool, cook green beans in a 3-quart saucepan of boiling salted water, uncovered, until crisp-tender, 3 to 4 minutes, then drain and transfer to a bowl of ice water to stop cooking. Let stand 2 minutes. Drain and pat dry.
• Just before serving, toss potato mixture with green beans, celery, parsley, and remaining 1/4 cup vinaigrette.

Steps:

• Stir together all ingredients except haricots verts with 3/4 teaspoon salt and 1/4 teaspoon pepper in a large bowl until combined well.
• Cook beans in a large pot of boiling salted water (1 tablespoon salt for 6 quarts water), uncovered, until crisp-tender, about 6 minutes, then drain. Toss with herb butter.
• Do Ahead
• Herb butter can be made ahead and chilled, covered, 3 days or frozen, rolled into a cylinder in plastic wrap and kept in a sealed bag, 1 week. Haricots verts can be trimmed 1 day ahead and chilled in a sealed bag lined with paper towels.
