Fava Bean and Zucchini Gratin
- TOTAL TIME: 1 HR
- SERVINGS: 6
Sprinkling this gratin with panko bread crumbs gives the topping a pleasant crunch.
- 4 pounds fresh fava beans, shelled (4 cups) shelled
- 2 tablespoons unsalted butter
- 1/2 cup panko (Japanese bread crumbs)
- 1 small onion, minced
- 1 small zucchini, halved lengthwise and thinly sliced crosswise
- Salt and freshly ground white pepper
- 1 cup heavy cream
- 1 teaspoon chopped tarragon
- Bring a large saucepan of water to a boil and fill a large bowl with ice water. Blanch the fava beans in the boiling water for 1 minute. Drain and transfer to the ice water to cool; drain again. Using kitchen shears, snip off a small bit of skin at one end of each fava and pinch out the beans. Discard the skins.
- Preheat the broiler. In a medium ovenproof skillet, melt the butter. Pour half of the melted butter into a small bowl and stir in the panko. Add the onion to the skillet and cook over moderately low heat, stirring occasionally, until softened, about 5 minutes. Add the zucchini, season with salt and pepper and cook over moderately high heat until softened and lightly browned, about 5 minutes. Stir in the cream, tarragon and fava beans and simmer over moderate heat until the cream is slightly thickened, about 5 minutes longer.
- Broil the vegetables 8 inches from the heat until the crumbs are toasted, about 2 minutes.
