Spaghetti and meatballs get spiced up with a classic Italian sauce. All'amatriciana hails from Amatrice, a town northeast of Rome. Classic all'amatriciana sauce is made from tomatoes, guanciale (salt-cured pig's jowl), and hot peppers. Here, bacon stands in for the guanciale.

A tagine is a Moroccan stew. In this version, tender beef meatballs are braised with vegetables, then served over herbed couscous.

In South Louisiana, any sauce is called gravy. This dish would be our equivalent of biscuits and sausage gravy, except we've got all this seafood down here that finds its way into nearly everything. Serve this gravy over biscuits ) with Oeufs au Plat , and you've really got something. As a chef, I make this a bit more complicated than it needs to be: I start with the shrimp in the pan, then remove them so they don't overcook, and then I add them back once it's all come together.

Editor's note: Serve this veal with Chef John Besh's Jalapeño Cheese Grits . Grillades is a Creole version of pot roast; the meat is sliced or pounded thin, then slow-cooked in a pungent sauce. If veal shoulder isn't available, substitute boneless, sliced Boston butts of pork. Sure, you can use a leaner cut of veal (and if you do, you'll want to cut the cooking time down by half). But I encourage you to find those cheaper cuts of meat that have much more flavor than either the loin or the leg.

Rustic and delicious, this healthy meatless stew is a hearty main course.

Rajas (strips) of crisp corn tortillas and sweet mini bell peppers make a colorful garnish.

This classic and delectable pasta dish originated in the region of Abruzzi, in the little town of Amatrice, northeast of Rome, where it was traditionally prepared without tomatoes. But it is the Roman version of pasta all’amatriciana, with tomatoes, that I share with you here—the version that is best known and deservedly popular. Lots of onions; chips of guanciale (cured pork cheek, now available in the United States, see Sources, page 340), pancetta, or bacon; and San Marzano tomatoes are the essential elements of the sauce, Roma style. Note that the onions are first softened in water, before olive oil is added to the pan—a traditional but unusual step that is said to make the onions sweeter. The standard pasta used is bucatini or perciatelli (spaghetti are only tolerated). The long, dry strands of perciatelli resemble very thick spaghetti but are hollow like a drinking straw. When cooked, they are wild and wiggly, so you might be tempted to cut them. Do not—once you’ve got them on your fork, they’re delicious and fun to eat. It is quite all right to slurp them. Indeed, as kids we would suck them in so fast that the end of the noodle would whip us in the nose, splattering sauce all over our faces. What a wonderful memory!

Andouille, the heavily spiced and smoked sausage that is a linchpin of so many Cajun dishes, adds its inimitable heat to an able stuffing stand-in. A swirl of cream gravy (above) can help quell the spice.

This quick soup, an American classic, makes a fine pairing with a grilled cheese sandwich or crisp romaine salad. Here the grilled cheese sandwich takes a different form—a souffléed Cheddar topping on a good piece of toasted sandwich bread.

Chilaquiles is a classic Southwestern casserole made from crumbled tortillas, tomato sauce, and cheese. Here, its savory flavors are augmented with black beans and zucchini.
