Moussaka

This version of the classic Greek dish layers eggplant with an aromatic meat sauce and creamy béchamel for a satisfying summer casserole. The eggplant slices are commonly fried, but here we broil them to cut back on calories. Graviera, a hard grating cheese, is popular in Greece. Look for it with other specialty cheeses at well-stocked grocery stores, or substitute Pecorino Romano.

Anti-Inflammatory Lemony Salmon & Orzo Casserole

This lemony salmon and orzo casserole is a one-dish dinner that’s packed with omega-3 fatty acids—a polyunsaturated fat in salmon that can help tame inflammation and may even help lower blood pressure. Here, omega-3-rich salmon sits on top of an orzo mixture that bakes in the oven, instead of boiling on the stovetop, absorbing all the bright and lemony flavors while it cooks.

Creamy Spinach-&-Feta Chicken Casserole

Inspired by the flavors of spanakopita, here we put a spin on spinach pie and turn it into a casserole. Adding chicken provides protein, while plenty of garlic and onions add flavor. This recipe calls for 8 sheets of phyllo dough, so there’s no need to cover them to keep them moist when assembling. If your sheets are larger than your dish, cut them or fold them in half so they fit.

Lasagna with Slow-Roasted Tomato Sauce

Slow-roasting the tomatoes gives the tomato sauce for this lasagna recipe an intense depth of flavor—which is then enhanced by the umami in onions, Parmesan and spinach. The lasagna noodles are layered into the lasagna uncooked; the moisture from the fresh spinach cooks them perfectly as the lasagna bakes in the oven.
