How to make this recipe
- Preheat the oven to 300°. In a medium enameled cast-iron casserole, bring the water to a boil with the tarragon and thyme sprigs and 1 teaspoon of salt.
- Add the pearl onions, cover and simmer over low heat until tender, about 8 minutes. Using a slotted spoon, transfer the onions to a large shallow baking dish. Add the carrots to the simmering water, cover and cook until tender, about 8 minutes. Transfer to the shallow dish. Repeat with the haricots verts (about 4 minutes) followed by the zucchini (about 3 minutes), and, finally, the red and yellow peppers (about 3 minutes). Cover the vegetables with foil and keep warm in the oven.
- Boil the vegetable cooking liquid over high heat until reduced to 1 cup, about 5 minutes. Remove from the heat and whisk in the butter, 1 tablespoon at a time. Stir in the minced tarragon, parsley, chives and garlic. Season with salt and pepper. Pour the sauce over the vegetables, toss gently and serve.
