2022 update. This recipe has seen millions of hits over the years, driven by it being mentioned in the Broadway musical Come from Away. Plenty of folks have found Rock Recipes from it and we are happy to welcome you all here.

Some will flinch at the suggestion of fish and cheese together, I get that. But this Cod au Gratin is one of the most requested recipes I’ve had on Rock Recipes.

It’s a dish that has been made here in Newfoundland for a long time. I think the mild neutral flavour of cod actually lends itself well to being paired with cheese.

Jarlsberg Cheese with white wine and crusty bread — Jarlsberg Cheese is another cheese that you can add to the mix.

As long as the cheese flavour is not too strong, that is. You can substitute many mild cheeses like mozzarella or even gruyere to make your own favourite version of this recipe.

A real crowd favourite.

This is a favourite thing for Spouse and I to serve when we have friends or family over for dinner. When it’s really casual we will cook and serve this in a covered casserole dish

When we want to serve it as individual portions though, I like to cook and serve it in individual gratin dishes

By request for a reader who is feeling a little homesick this week. This is a pretty basic recipe but still has plenty of flavour. Hope you enjoy!

2017 Update: This recipe has proven to be one of the most popular of the past 10 years on Rock Recipes.

I cannot count the number of times that someone has mentioned it to me online and in person at book signings and other events. If you’re a cod fan, this is definitely a must-try recipe.

Cod au Gratin. New video recipe!! One of our most popular recipes in 15 years online. This version is easy to prepare and gets rave reviews every time.

Ingredients

3 pounds fresh cod fillets
3 tablespoon butter
3 tablespoon flour
2 cups whole milk
2 tablespoon Dijon mustard
1 teaspoon finely grated lemon zest
Salt and pepper to season
½ cup shredded parmesan
1 teaspoon summer savoury, dill or tarragon make good substitutions
1 ½ cups shredded mild cheddar cheese
1 cup cracker crumbs
1 tablespoon olive oil

Instructions

Scald the milk in the microwave for about 4-5 minutes until just under the boiling point.
Meanwhile, in a medium saucepan add the butter and flour and cook together for 2 minutes. Slowly pour in the scalded milk whisking constantly.
Cook until the sauce begins to thicken. Add the lemon zest, Dijon mustard, savoury and season with salt and pepper to taste. Add the Parmesan cheese just before pouring onto the fish.
Arrange the fish in the bottom of a greased 9×9 inch baking dish or in individual gratin dishes. Pour the sauce over the fish. Top with the cheddar cheese.
Mix the cracker crumbs with the olive oil and sprinkle over the cheese. (You can add a little extra savory to the crumbs if you like, about ½ tsp). Bake for 45 minutes to an hour at 350 degrees F until bubbling and the top has evenly browned. Individual gratin dishes should take about 25 -30 minutes, just check the center to see that the fish has fully cooked
