Dry white wine and Gruyère cheese give this fish casserole a rich flavor that hides its virtue. Before baking, we top the dish with seasoned whole-wheat breadcrumbs, which add a wholesome, nutty flavor and dietary fiber. For variety, you can substitute almost any mild white fish.

Mediterranean Roasted Fish & Vegetables

Here's a roasted fish entree plus side dish all in one package. Besides the convenience of one roasting pan, both the fish and the vegetables get the benefit of their flavors mingling as they cook side by side. The recipe calls for a firm white fish, such as striped bass or cod, but salmon would also work beautifully with the fennel, potatoes and tomatoes.

Seafood Chowder Casserole

New England seafood chowder inspired the flavors here, but we've enhanced them further with Gruyère cheese and a crispy crumb topping. We like the combination of shrimp, cod and crab, but feel free to experiment with other types of seafood--scallops, clams and mahi-mahi would also work well.

Quick Shrimp Enchilada Bake

Shrimp enchiladas offer a taste of coastal Mexican cuisine but some versions contain so much cheese, butter and sour cream that they can pack a whopping 50 grams of fat per serving. Our version has vibrant flavor and only half the calories and 6 grams of fat per serving, plus we use precooked peeled shrimp so you can get the dish on your table fast enough for a weeknight supper. The addition of refried beans helps makes these enchiladas an excellent source of fiber as well.

Puglian-Style Paella

In this Italian paella recipe, potatoes and other vegetables are layered with mussels and rice and baked in a casserole dish. Be sure to cover the rice completely with vegetables to ensure it cooks properly.

Skillet Tuna Noodle Casserole

39
Known as Tuna-Pea Wiggle to some, this family-friendly tuna noodle casserole tends to be made with canned soup and whole milk, which means high fat and sodium. We remedy this by making our own creamy mushroom sauce with nonfat milk thickened with a bit of flour. Look for whole-wheat egg noodles--they have more fiber than regular egg noodles (but this dish will work well and taste great with either).

Spicy Shrimp Casserole

Shrimp takes center stage in this spicy Mexican-inspired casserole. It's loaded with corn, green salsa, and Monterey Jack cheese and topped with crunchy homemade tortilla strips.

Recipe developer Katie Webster's grandmother used to make a version of this dish with fresh-caught smallmouth bass from Vermont's Lake Champlain. Our updated version requires no fishing; just a trip to the supermarket for Pacific cod or tilapia.

Tuna-&-Tomato Mac & Cheese

Tuna mac & cheese takes a trip to the Southwest with spicy tomato and festive blue tortilla chips on top. Canned tomatoes with green chiles and ancho chile powder add a peppery kick, but if you like, you can keep it mellow by using a 14-ounce can of drained petite diced tomatoes and mild chili powder.
