Lentil and Bean Stew with Gremolata

半杯热油倒在一个大荷兰烤箱里,媒介-high. Add onion, carrots, and celery. Cook, stirring occasionally, until tender, 15 to 20 minutes. Stir in tomatoes, 1 tablespoon garlic, 2 teaspoons salt, and 1 teaspoon pepper. Cook, stirring often, until garlic is fragrant and tomato juices begin to caramelize, 4 to 6 minutes. Stir in lentils, bay leaves, rosemary sprigs, and 5 cups water. Bring to a boil over medium-high. Reduce heat to medium-low, and simmer, uncovered, stirring occasionally, until lentils are just tender, 20 to 25 minutes.

Meanwhile, stir together parsley, lemon zest, 1/2 teaspoon salt, and remaining 1 tablespoon garlic. Let mixture stand 10 minutes. Stir in remaining 1/2 cup oil, and season with salt to taste.

Add beans, remaining 4 teaspoons salt, and remaining 1 teaspoon pepper; stir to combine. If needed, stir in additional water to thin stew. Cook over low, uncovered, stirring occasionally, until beans are heated through and lentils are tender, 10 to 15 minutes. Stir in lemon juice, and season to taste with salt and pepper. Spoon gremolata over servings of stew.
