If you are looking for a new fish recipe, you must try my cod with mustard sauce! Cod filets are smothered in a mixture of sour cream and two types of mustard, then baked in the oven till done. Juicy and flavourful. Even non-fish lovers will appreciate it!
It seems that no matter how creative we get in order to serve balanced meals to our family we struggle to find fish recipes that our kids and sometimes partners will love. Salmon is an easier sell but cod is a bit too bland. Who is with me?
However, cod is readily available fresh or frozen. It’s packed with vitamins and minerals our bodies need. Cod is also relatively inexpensive. So many reasons to include it in your weekly shopping. All we need is a good recipe!
The one I am sharing today is inspired by Ina Garten’s recipe. I adapted it by using cod instead of red snapper and leeks instead of shallots as well as varying the baking method.
This is a truly gorgeous fish recipe. I believe that even fish haters might go along with this one.
As I mentioned above, cod has a very mild taste, and therefore needs a flavourful sauce to give it a bit of a lift. In short, it needs to be made more interesting. Here is where mustard comes in!
How do I make a sauce for cod?
Great news is that you can whip up a delicious sauce in a matter of minutes. The prep is minimal.
All you do is mix up full fat sour cream or creme fraiche, chopped leek, Dijon and whole grain mustard sauce with a tablespoon of capers.
How long do I bake cod in the oven?
Most fish cooks amazingly fast. It take mere minutes in the oven. That is why it’s such a great dinner option on a weeknight.
Cod fillets will only take 10 to 12 minutes of baking at 425F/210C plus 2 minutes of broiling for the sauce to get an appealing blistering on top. For extra thick fillets allow for 15 to 20 minutes of baking time.
Make sure to pat your fish dry with paper towels before covering it with the mustard sauce. It will still release quite a bit of liquid as it bakes but this way you will reduce the amount of it.
Can I use frozen fish?
Absolutely. Using frozen cod is a delicious and economical way to get fish into your family! Just make sure you defrost it in a fridge, then pat dry with paper towels before covering with the sauce.
This baked cod recipe is a real winner. Tt pairs a delicate tasting fish with strong and bold flavours of mustard. The first bite reveals a perfectly cooked fish that is succulent and moist as it should be!
What should I serve with baked cod?
Fish goes so well with rice, potatoes or cauliflower rice if you are going low carb. The mustard sauce in this recipe is ideal for flavouring your side as well.
I served it with Herby Sweet Potato and Swede Mash and it was a beauty of a dinner. Simple, elegant, good enough to present to guests while light and healthy! Win!
