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.

  • 2 tablespoons extra-virgin olive oil, divided
  • 2 medium onions, very thinly sliced
  • 1 cup dry white wine
  • 1¼ pounds cod (see Tip), cut into 4 pieces
  • 2 teaspoons chopped fresh thyme
  • ½ teaspoon kosher salt
  • ½ teaspoon black pepper
  • 1½ cups finely chopped whole-wheat country bread, (about 2 slices)
  • ½ teaspoon paprika
  • ½ teaspoon garlic powder
  • 1 cup finely shredded Gruyere, or Swiss cheese


  • Active

  • Ready In

  1. Preheat oven to 400°F.
  2. Heat 1 tablespoon oil in a large ovenproof skillet over medium-high heat. Add onions and cook, stirring often, until just starting to soften, 5 to 7 minutes. Add wine, increase heat to high and cook, stirring often, until the wine is slightly reduced, 2 to 4 minutes.
  3. Place cod on the onions and sprinkle with thyme, salt and pepper. Cover the pan tightly with foil; transfer to the oven and bake for 12 minutes.
  4. Toss bread with the remaining 1 tablespoon oil, paprika and garlic powder in a medium bowl. Spread the bread mixture over the fish and top with cheese. Bake, uncovered, until the fish is opaque in the center, about 10 minutes more.
  • Tip: Overfishing and trawling have drastically reduced the number of cod in the U.S. and Canadian Atlantic Ocean and destroyed its sea floor. For sustainably fished cod, choose U.S. Pacific cod or Atlantic cod from Iceland and the northeast Arctic. For more information, visit Monterey Bay Aquarium Seafood Watch at

one of the best fish recipes this dish was a winner in my family, including the people that don't like fish. i used many other types of fish for the recipe. I put my bread in a food processor with extra olive oil and salt and it was good. but i agree that there are too many onions.Also try adding a little extra thyme Pros: not a very strong fish flavor, LOVE the taste Cons: better to use Chedder than Gruy+¿re cheese

Yummy! I loved this dish! the combo of wine with the cheese and onions was awesome. Mine was a bit salty..I would say, go easy on the salt- other than changes- so easy to make! Pros: Easy, Fast

French Onion Soup meets Cod I don't like fish, my kids don't like fish. My husband does. This dish is a great compromise because the cod doesn't overpower the flavor of the dish. If however you're a fish lover, and really enjoy cod, I can see why some of the other reviewers didn't care for the dish. I used whole wheat bread for the croutons and lots of paprika. Pros: Cheese masks the flavor of the fish, easy to make and the house doesn't smell like fish.

Excellent flavour for white fish I used halibut instead of cod because I had it on hand. Didn't have any bread in the house, so used seasoned Italian bread crumbs and added the garlic, etc. Mixed the shredded cheese with the bread crumbs so we didn't end up with a lump of melted cheese on the fish. Outstanding week night dinner.

Terrible waste of cod I'm sorry, cheese and fish don't mix. I love both Gruyere and cod fish, but this recipe was terrible! The texture of heavy melted cheese with the tender cod just do not go well together. And the flavors didn't meld. Perhaps the recipe could be salvaged by leaving out the cheese and including something simple that complements rather than overpowers the cod. Pros: Quick Cons: Flavors don't mix, texture is not good

A good twist on Cod I cooked this for a dinner way to make cod. It turned out fine. I Love cheese but can only do the no salt swiss and I thought it did ok when backed on. but I might have baked it too long. I would like my cheese a little bit more softer. Pros: tasty, tender, easy to cook.

Easy and very Tasty Made it in a Teflon Pasta pot with oven proof lid. Used Gruyere, dried Thyme and I know, Oh No! bottled Cooking White wine. The key to perfection was slice the onions thin, and don't let them burn in the beginning. Add the wine when they just turn flexible. They will caramelize into a wonderful sweet brown later on. Use Spanish Yellow onions. I went with store bought Rosemary focaccia bread for crumbs. Oh and remember gas ovens are hotter and cook quicker so don't stick exactly to the times or fish will overcook. Definitely keeping this recipe! Pros: Gryere is only exotic ingredient Cons: None

Bland The recipe was fine and I appreciate that cod does not stink up the kitchen. It just was not all that exciting. Pros: Easy to make Cons: Boring

Thanks for the Inspiration! This recipe sounds good as is, but I wanted to use up some things I already had in the house so did not follow the recipe exactly. Rather, I used it as a base and it turned out GREAT! Instead of onions I used 2 leeks and 2 shallots. I did use gruyere, but used a 9-grain artisan loaf for the bread. To save time, I used the food processor to turn the bread into crumbs instead of finely chopping, and added ground flax seed to the bread crumbs (just for the extra health benefits). The wine I had open was not very dry, but it wasn't overly sweet either so it worked well. I also used tilapia instead of cod. So good! Pros: Fast, easy, versatile
