Before cooking with leeks, you will need to clean them. Since they are grown in sandy soil, the bottom of the leeks will usually have some dirt attached. It’s easy to clean them — take a look at our tutorial for cleaning leeks.
6 medium leeks, white and light green parts, cleaned of all sand
2 tablespoons of olive oil
1/2 teaspoon Herbs de Provence
1/2 teaspoon salt
1/2 teaspoon fresh ground black pepper
1/2 cup chicken or vegetable stock, see our homemade stock recipe
Heat the oven to 400 degrees F. Cut the leeks in half, lengthwise.
In a rimmed baking sheet, toss the leeks with olive oil, Herbs de Provence, salt and pepper. Roast the leeks until they are tender, 35 to 45 minutes. After 10 minutes, add a few spoonfuls of broth to the leeks so they keep moist repeat as needed.
