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.

Ingredient Checklist

Directions

Instructions Checklist
  • Preheat oven to 400 degrees F.

    Advertisement
  • 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.

  • 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.

  • 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.

Tips

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 seafoodwatch.org.

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 Read More

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. Read More

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. Read More

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 Read More

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. Read More

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 Read More

Absolutely love this recipe. The gruyere with the the fish and onions works very well for mild flavor and developes many layers on the palate with each bite. My very fussy 14 year old daughter will only eat fish prepared this way. Read More

Used Haddock did not reduce the white wine enough so the fish fell of the onions still a great dish. Thanks Read More

I made several substitutions (basically I just had the fish!) to this recipe but it still was wonderful! I didn't have white wine so I used chicken broth plus a drizzle of honey. I didn't have fresh thyme but used dried italian herbs (primary ingredient was thyme). I didn't have swiss (or gruyere) cheese so used mild cheddar instead. I also used multigrain bread instead of whole wheat...the added texture and "nuttiness" really enhanced the flavor! My picky husband and son gave this dish a thumbs up! Read More

This was surprisingly good...and quick to boot. Start to finish in less than 30 minutes! I subbed tilapia and I found that there were a bit too many onions (and I love onions)--otherwise it was wonderful! Read More

This is an excellent dish very suited to the cold weather. The gruyere makes this dish. I had to fight to get this one the first time but have been getting lots of requests for repeats now. Even my 7 year old loved it. The only change I made was to use very finely diced homemade bread for the topping which added a rustic feel to the dish. Read More

Surprisingly good! I usually avoid any fish and cheese combo but this worked well. Our whole family enjoyed it with rosemary roasted potatoes on the side. Adjustments I made: 2 large shallots instead of onions and smoked paprika instead of regular. Also I used a seedy whole-grain bread for the breadcrumbs - it definitely made the dish. Sauce needed much better seasoning though - next time I would add some dijon and more salt with the wine or maybe some garlic too. But I'll definitely be making it again - so easy and delicious.

This recipe has become a weeknight standby for me. I thought 2 onions was a bit strong the first time I made this meal so the next time I used shallots and a different time leeks - both were great. I used sherry because I always have it on hand. My husband always says he doesn't like fish but he loves this recipe. I tend to use the swiss cheese because it's a bit less expensive than gruyere. I've made this with Cod and Talapia. Read More

Great dish feels like you are eating something healthy ya know? Had LOTS of onions. Couldn't tell there was cheese in it at all really. It goes in the "may or may not make again" pile for me! Read More

Baked Cod casserole I made this with haddock and it turned out well. Since my husband does not like swiss cheese I used a mixture of reduced fat provolone mozzarella asiago and romano. We both liked it and I plan to fix it again. Read More

Very Yummy and Stick to Cod Only This dish is fabulous. Cod tastes fantastic with the sweet onions and thyme. I do not recommend using other fish as I tried tilapia and it did not marry well with the onions. Stick to the yummy cod. I served it with a side of potatoes and was so full that you would have never known it was fish. Just great! I will make this again and share it with friends. Pros: Light filling tasty Cons: It says you can substitute other fish but I tried it and did not like it with other fish. Read More

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 Read More
