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 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.

Fresh cod is a staple of Newfoundland cooking but I’ve often used frozen in 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!

Cod au Gratin - one of our most popular recipes ever! Some may balk at the suggestion of fish and cheese together but with truly fresh cod, this dish is delectable.

Ingredients

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

Instructions

  1. Scald the milk in the microwave for about 4-5 minutes until just under the boiling point.
  2. Meanwhile, in a medium saucepan add the butter and flour and cook together for 2 minutes. Slowly pour in the scalded milk whisking constantly.
  3. 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.
  4. Arrange the fish in the bottom of a greased 9x9 inch baking dish or in individual gratin dishes. Pour the sauce over the fish. Top with the cheddar cheese.
  5. 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

Can someone please confirm if they freeze this before cooking or if they cook it, let it cool, then freeze and defrost and reheat?

This is a huge family and guest favourite. I make it with any white fish and often put it on a bed of cooked rice then adding only salad to the meal. sometimes I leave off the top crunch to cut calories. . . .It is still divine!

Nice but too much mustard, I think 1 tbsp or even 1tsp is enough. 2 tbsp overpowers everything. Made it with fresh Hamour (grouper) Cod is only available frozen here.

well, Barry, I cooked this up tonight. Used haddock instead of cod because it was in my freezer. And I have to tell you, it was absolutely delicious! And, that is coming from a person who isn't a huge fish fan. Thanks so much. it will become my go-to fish recipe.
