SUMMER
Caramelized Onion, White Bean and Wilted Arugula Crostini
Cooking onions for a long time over low heat brings out their sweetness, which is a perfect complement to mellow beans and sharp arugula. Serve with a crisp green salad for a light supper.
Serves 4
3 tablespoons pine nuts
2 tablespoons olive oil, divided
2 large yellow onions, thinly sliced
Salt and black pepper
2 teaspoons fresh rosemary, chopped
1 can (15 ounces) white kidney or cannellini beans, drained and rinsed
3 cups (about 2½ ounces) baby arugula leaves
4 thick slices whole-grain bread
1. Warm a large nonstick skillet over low heat. Add pine nuts; toast 1 minute, until lightly browned, stirring. Remove pine nuts from the skillet.
2. Warm 1 tablespoon of the oil in the same skillet over medium-low heat. Add onions; cook 5 minutes, stirring. Reduce heat to very low; cover pot and let cook 25 minutes, until onions are very tender and golden, stirring often. Season with salt, pepper and rosemary. Increase heat to medium; stir in beans and arugula. Cook until beans are warmed through and arugula wilts, stirring. Add a tablespoon or two of water if the mixture becomes too sticky.
3. Meanwhile, preheat oven to 350°F. Place bread slices on a baking sheet, brush with the remaining tablespoon of oil and bake 10 minutes, until toasted. Top each toast with some of the onion mixture; garnish with toasted pine nuts.
TIP: When caramelizing onions, keep the heat very low and keep stirring. You want the onions to be a light golden brown, not burned. Drizzle in a bit more oil if onions are overbrowning.
