6 medium leeks
20 thick asparagus spears (about 1 pound)
1 tablespoon olive oil
1/2 teaspoon salt
Freshly ground pepper, to taste
Balsamic vinegar (optional)
- Trim each leek at the root end, making sure the stalk stays intact, then cut off the top where the green part begins. Cut leeks in half lengthwise. Immerse in a bowl of cold water to loosen any sand or grit. Rinse under cold running water, and pat dry.
- Heat oven to 400 degrees. Trim tough ends from asparagus. In a large bowl, combine asparagus and leeks. Drizzle olive oil over vegetables, and toss to coat. Add salt, and season with pepper; toss to combine.
- Place vegetables in a heavy roasting pan, and transfer to oven. Roast until vegetables start to turn brown and are fork tender, about 25 minutes. Remove pan from oven, and set on heat-proof surface until vegetables are cool enough to eat. When ready to serve, drizzle with balsamic vinegar, if desired.
