This baked stuffed fish may be made with any mild, white, and thin fish fillets. Sole and flounder are excellent choices, and tilapia can work as well. The fish is uniquely baked in muffin cups with the stuffing in the center. The stuffing is a combination of fresh breadcrumbs, sage, and chopped celery.

Serve this baked fish with your favorite sides, such as steamed vegetables, rice pilaf, french fries, or a tossed salad. Some homemade cornbread would be a good addition to the meal also, along with coleslaw. It's a great make-ahead dish, and it freezes well, too.

  • 1 teaspoon kosher salt, plus more to taste

  • 3 tablespoons finely chopped onion

  • 1/2 cup finely chopped celery

  • 6 tablespoons butter, melted

  • 1/8 teaspoon freshly ground black pepper

  • 1 teaspoon dried sage, crumbled

  • 4 cups dry bread, cut or torn into 1/4-inch pieces

How to Store and Freeze Baked Stuffed Fish

This dish will keep for two to three days in the refrigerator as long as it's in a sealed container. If you'd like to freeze it, wrap each stuffed fish individually and then transfer it to a zip-close bag to freeze. Defrost, wrapped in foil, in a 350 F oven until completely hot.

How do you know when fish is cooked?

Fish turns an opaque color when it is done cooking. Test for doneness with a fork. When it is finished, your fish should flake easily. In terms of temperature, fish is ready when the interior reaches 140 F with an instant-read thermometer.
