Basil Onion Sauce

You have certainly played around with fresh basil, particularly with pesto. Here the flavor is more subtle in its cooked form.

Recipe information

  • Yield

    makes about 1 cup

Ingredients

2/3 cup fresh, unblemished basil leaves, packed
3 tablespoons best-quality extra-virgin olive oil
1/2 pound onions, cut in 1-inch pieces (about 1 1/2 cups chunks)
1 cup leek chunks (1-inch pieces)
2 cups water
1/2 teaspoon salt

Preparation

  1. Step 1

    Reserve 5 or 6 bright-green basil leaves (about 2 tablespoons) and 2 tablespoons of the olive oil. Put the remainder of the basil in a small saucepan with all the other ingredients (including the remaining tablespoon of olive oil). Bring the water to a boil, cover the pot, and boil gently for 15 to 20 minutes.

    Step 2

    Remove the cover and boil steadily another 20 minutes or longer, reducing the contents of the pot to 1 cup—about a quarter of the original volume. Lower the heat if necessary, as liquid evaporates, to avoid burning the sauce ingredients.

    Step 3

    When it is sufficiently concentrated, scrape everything from the pot into the bowl of a food processor and purée. Roughly chop the reserved basil leaves with a knife, then add the pieces to the food processor and purée until they’re incorporated. Finally, with the machine running, drizzle in the reserved 2 tablespoons of excellent olive oil, to form a light emulsion.

    Step 4

    Serve the sauce warm with cooked vegetables; reheat on the stove if it has cooled off. Store in the refrigerator.
