Corn Bread Casserole

Go to Recipe

Corn bread casseroles are a too-busy cook's dream. A handful of pantry staples--frozen and canned corn, corn muffin mix, butter, sour cream and an egg--are baked into something delicious and comforting. We jazz ours up with shredded cheddar and sliced scallions. You can keep it classic and skip the mix-ins, or you can add whatever you have on hand.

Broccoli and Wild Mushroom Casserole

Go to Recipe

Photographer and Alabamian Robert Rausch grew up eating vegetable casseroles—he and his mother are both vegetarians. The broccoli casserole his family ate is a step up from the standard church cookbook recipe, which calls for using canned mushroom soup: In place of that, he uses wild mushrooms. He still relies on Ritz crackers, though, for the crispy, buttery topping.

Artichoke Bread Pudding

Star Ingredient: Quercus Umbriae Giudia Artichokes

If cooks were asked to name the vegetables they find most intimidating and time—consuming to prepare, artichokes would surely top the list. Marinated artichoke hearts from Umbria in central Italy solve the problem: No trimming, cooking or choke removal is required.

Polenta Gratin with Spinach and Wild Mushrooms

Go to Recipe

Commercial wild mushroom mixes (usually a combination of shiitake, cremini and oyster mushrooms) are a godsend: Some invisible helper has already cleaned, stemmed and sliced the mushrooms for you. In this recipe, they are mixed with spinach and cream, then baked in a luscious gratin under smooth rounds of precooked polenta until bubbling hot.

Note: Make this dish with vegetable broth to keep it vegetarian-friendly.

Cauliflower Pilaf

Go to Recipe

This fragrant side dish was born out of an argument between Bruce Aidells and Nancy Oakes on whether an entire head of cauliflower could be filled like dolma, the Middle Eastern family of stuffed grape leaves and vegetable dishes. “Nancy thought it could be done; I didn’t,” he says. Aidells turns the idea of dolma inside out by topping a rice casserole with cauliflower florets. “I’m the lazy, more practical cook,” Aidells says.
