Step 1

Preheat oven to high broil with rack in the middle position. Place asparagus on a rimmed baking sheet, and drizzle with olive oil; toss to coat. Sprinkle with salt, and broil until asparagus is crisp-tender; about 3 to 5 minutes. Do not stir the asparagus.

Step 2

Meanwhile, make the sauce: Combine the yogurt, garlic, dill salt, pepper, and lemon juice and whisk until creamy and smooth. Taste to adjust flavor and drizzle with olive oil.

Step 3

Arrange roasted asparagus on a platter. Spoon Dill Yogurt Sauce over the asparagus spears. Add lemon zest and freshly ground pepper for garnish.
