Dijon-Crusted Fish

Dijon, Parmesan and a hint of horseradish give this toasty fish lots of flavor. The preparation is so easy, it takes just 5 to 7 minutes to get four servings ready for the oven. —Scott Schmidtke, Chicago, Illinois

    Delicious and very easy to prepare. I was out of horseradish so it was omitted. Everything else by the recipe. Definitely will add this to my fish routine.

    WOW was this ever good. And so easy to make. I didn't have any horseradish in the house so I left it out and put in an eighth tsp. of garlic powder and onion powder. I did everything else just like the recipe. Everyone thought it was extra good. I will be making this often. I am not usually a great lover of fish but tonight the tilapia was the best ever.

    So good! I made this with Mahi Mahi and used the same cook time. Like others I omitted the butter so felt less guilty using regular mayo. I put these over a bed of Arugala tossed lightly with balsamic and olive I was plating I looked over at the left over mayo sauce (and since I didn't put the fish directly into the bowl I dropped about a half teaspoon of honey into it and then frizzed this honey mustard sauce over salad and fish...It was a beautiful presentation and everyone loved it! Thank you Sooo much.

    Made this once with tilapia and tonight with cod. I believe I liked it better with tilapia, which surprised me. Very thankful that I have this recipe that my husband likes and it is baked, not fried!

    Fabulous recipe. I used cod which turned out to be a great choice. I omitted the butter in the crumb topping. The mayonnaise/butter mixture was rich enough to make this a one a great choice, VFE. I will be making this one again.

    Excellent, simple and easy to make. I would add more horseradish next time for more kick...and I also used Panko crumbs which worked well. This recipe will work with almost any kind of fish filet.

    I liked it, but my wife didn't think it was anything special, so splitting the difference in the rating. We used cod instead of tilapia, but I thought it was fine, and relatively easy/quick to make.

    This is really good. So simple and yet so delicious Tilapia was fish of choice. One note - may want to increase horseradish just a little to provide some pop. I would suggest to follow the recipe first time around as written and second time tweak to your liking!

    Wow. This is hands down the best recipe for Tilapia I have ever made. I added a little more than a teaspoon of horseradish (because I love horseradish) and omitted the butter. I felt like the fat from the mayo was sufficient. The breadcrumb mixture still browned and crisped perfectly. Absolutely delicious!
