Recipe: Zucchini, Squash, and Corn Casserole

There's nothing quite as delicious in the summertime as fresh zucchini, squash, and corn—and there's certainly nothing like it when that trio of fresh vegetables are baked together in a flavorful side dish casserole. Soft, white breadcrumbs double as a feather-light binder and a golden crumb topping, since they brown ever so slightly atop the casserole and add a subtle crunchy texture to the smoothness of the zucchini, squash, and corn. To make the bread crumbs, pulse torn slices of day-old white sandwich bread in the food processor until they are an ideal size. They'll be perfect casserole toppers—and easy and cost-effective, to boot.

Recipe: Fennel-and-Potato Gratin

This cheesy potato gratin gets a punch of flavor from nutmeg and fennel. It's impressive enough for a holiday party, but it is also easy enough to put together on a busy weeknight. We like the combination of nutmeg and fennel for a holiday party—there is a depth of flavor in the combination of spice that adds such a substantiality to the dish. It feels very special amidst flickering candlelight and shimmering holiday decorations. It's a perfect complement to roasted turkey, sweet ham, or sliced beef. It's also easy enough to whip up en masse if you have a large group to feed.

Butternut Squash Gratin

Recipe: Butternut Squash Gratin

We know and love potato gratins, but the addition of butternut squash to this beloved dish has made us fall for it all over again. Butternut squash goes well with so many dishes, but its addition to gratin is really out of the ordinary. The butternut squash and potatoes blend beautifully, and they add both heft and flavor to the casserole dish. Preparation tip: You'll want to slice the potatoes as you use them and place them in each layer (rather than slicing them all at once). Doing this will help to prevent oxidation in the potatoes and will ensure that your dish is as fresh as can be.
