If you are looking for a new fish recipe, you must try my cod roasted in mustard sauce! Even non-fish lovers will appreciate it!
A couple of weeks ago we stopped to say good-bye to a friend who is returning to Canada after years in England. She’d mentioned if I took as much of her stuff as possible I would be doing her a favour.
What was I to do but help?! After about half hour of sorting through her kitchen I walked away with many bags full of spices, various types of cooking oil, cans of food and Ina Garten’s “Back to Basics” cookbook.
The latter acquisition is my favourite, scratch that…actually it’s a tie with Kilner’s glass jars, which are already in use by storing newly made pickles.
Although I have dozens of cookbooks I was absolutely thrilled with a new one. Ina Garten is the queen of quick and no fuss meals that taste amazing.
The recipe for cod roasted in mustard sauce comes from her Back to Basics cookbook. I only slightly adapted it by using cod instead of red snapper and leeks instead of shallots and varying the roasting method a bit.
I cannot tell you enough what a gorgeous fish recipe it is, even the fish haters might go along with this one.
The prep is minimal. All you do is mix up a little mustard sauce, cover the fish with it and stick it in the oven for 15 minutes.
It’s that easy but wow what you get in return is sheer beauty.
Apparently this recipe for cod roasted in mustard sauce was shared with Ina by a wonderful French cook and let’s face it the French are all about elegant less is more attitude!
The recipe is a real winner because it 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!
I served it with Herby Root Vegetable Mash and it was a beauty of a dinner. Simple, elegant, good enough to present to guests while light and healthy! Win!

Hi Becky, creme fraiche is a dairy product similar to sour cream but less sour. You can use full fat sour cream instead.
Betsy Bix says
This was delicious. I served it with sauted spinich an grape tomatoes with s/pilotonline and some bit of Italian seasoning. Will definitely make again.

vikalinka says
I am so glad you found my blog too, Nicola! That cod recipe is one of my favourite ways to cook fish!
Mandy says
This was an amazing recipe. It is so easy to make. I had brown beer mustard, and mixed it with sour cream. I cooked it for the same amount of time and it was so delicious. It is so tangy from the mustard, but the tart bite it taken out from the sour cream. This is so fast, so cheap, and so delicious.

Steve is not a lover of fish dishes, but I think I’ll have to pursued him to try this! I would love to eat more fish. I’m feeling inspired :-)) x
vikalinka says
I am so with you on this one, Louise, Brad only likes mild tasting fish like cod but I love salmon. I constantly try to incorporate more fish in our diet but the family is still rebelling. 🙂 This recipe is pretty safe though, I hope he likes it!
Lucy Parissi says
This looks suspiciously healthy. Is it? I couldn’t bear it. My healthy(ish) diet has taken a major dive the past 3 days. I must confess to not cooking enough fish. But I do like mustard so this sounds like a must try recipe. xx
vikalinka says
I would absolutely put this recipe in the healthy category,Lucy! I don’t cook enough of fish either…not sure why…I blame it on the family.
