Summer Squash Gratin with Salsa Verde and Gruyère image

Number Of Ingredients 9

2 pounds summer squash
1 1/2 cups fresh breadcrumbs
3 tablespoons unsalted butter
3/4 cup sliced shallots
1 teaspoon minced garlic
1 tablespoon thyme leaves
1/2 cup salsa verde (see page 132)
1 cup grated Gruyère cheese
Kosher salt and freshly ground black pepper

Steps:

Preheat the oven to 400°F.
Cut the squash into 1/8-inch-thick slices. If you're using long zucchini-type summer squash, slice them on the diagonal. Toss the slices in a large bowl with 1 teaspoon kosher salt, and let sit 10 minutes.
Place the breadcrumbs in a bowl.
Heat a small sauté pan over medium heat for 1 minute. Swirl in the butter and cook a few minutes, until it browns and smells nutty. Pour the brown butter over the breadcrumbs (being sure to scrape all the brown bits into the bowl with a rubber spatula). Wait a minute or so for the butter to cool, and toss well.
Drain the squash and transfer it to a large mixing bowl. Add the shallots, minced garlic, thyme, 1/2 cup salsa verde, and some pepper. Toss to combine, and add the cheese and half the butter-coated breadcrumbs. Toss again, and taste for seasoning. (The raw garlic will taste strong at this point but will be delicious when cooked.)
Place the squash in a pretty 9-by-9-inch (or equivalent) gratin dish. Scatter the remaining breadcrumbs over the top, and bake 35 to 40 minutes, until the squash is tender and the top is crisp.
