This is a recipe of The Barefoot Contessa’s, Mustard Roasted Fish, that I’ve making for 12 years now. Every single time I make it, it turns out absolutely delicious!!! It’s a recipe that I can rely on to turn out exactly how I want it to each time I prepare it. That being said, it makes it perfect for when you are serving guests or for someone that you want to impress with your culinary skills. It’s a comforting dish while at the same time light feeling. I love to serve it with rice and lots of vegetables on the side.
For some, buying a whole fish fillet might be intimidating but I promise you it is so easy to make. If you don’t have a scale at home, you can ask the fish monger to cut the large fillet for you into 4-6 (8 ounce) fillets. In this recipe you can roast the fish with the skin-on or skinless. I always prefer the fish with the skin-on because it adds more flavor to the flesh as it’s being cooked and keeps it moist.
Crème Fraîche is a thick cultured cream with a nutty flavor. In French it literally means “fresh cream” and is similar to North American sour cream or Mexican crema fresca. Crème fraîche is less sour than sour cream and has a higher fat content. It’s the perfect base in this creamy Dijon sauce and pairs very well with any roasted fish. In North America you can find it in you specialty cheese section at your local grocer.
