Why It Works

  • Starting the salmon in a skillet and then finishing it under the broiler crisps the bottom surface of the fillets and cooks them through evenly.
  • Topping the salmon with a mixture of fresh breadcrumbs, mustard, and butter gives the top surface of the fillets a crispy crust while also seasoning the fillets and insulating them from the heat of the broiler.

There are three kinds of recipes. The first are the kind that totally, for lack of a better word, suck. Fool me once; I never make those again. The second are the terrific kind, but they just feel like a one-off. An occasion recipe, maybe, for novelty. And the third are the most rare, and the most wonderful. The ones that you make, and then make, and then make, and then make again.

For me, this crunchy, mustardy salmon is by far and away the third kind of recipe, so much so that, since my parents are in town, I am making it for them along with a batch of my roasted ratatouille lasagna napoleons.

This is my favorite way to cook salmon, and it's also the easiest. The concept is simple: salmon and mustard go well together. I lightly butter the bottom of two fresh salmon fillets (my market makes sure they are skinless and boneless) and set them in a skillet. While they get crispy on the bottom, I make a kind of savory crumble of breadcrumbs, two mustards, thyme, and butter. I pile it on top of the salmon while it's still in the pan, and transfer the whole thing to the oven.

The salmon finishes cooking and the crumbs get crispy and nutty and tangy and spicy from the mustard. It's kind of like an easier, lighter, more elegant way of getting crisp fried fish, with a little French flavor and flair. The whole thing is perfect.

I serve it on a bed of blanched fine green beans, or next to a salad. But what's next to it is not important. It's just about the salmon, so buttery, so tender, so good, and perfect, and earthy and wholesome, that I just can't stop making it! I made it for Mr. English and myself, but he was late in getting home, so I took the opportunity to pack it up for lunch the next day. And I'm happy to report it's just as good cold!

Ingredients

  • 2 slices high-quality white sandwich bread, crusts removed, torn into rough chunks

  • 2 boneless skinless salmon fillets, about 6 ounces each

  • Kosher salt and freshly ground black pepper

  • 1 tablespoon unsalted butter, softened, plus extra for the salmon

  • 1/2 tablespoon Dijon mustard

  • 1 teaspoon whole-grain mustard

  • 1 teaspoon fresh thyme leaves

Directions

  1. Preheat the broiler to high and adjust rack to 6 inches below the element. Pulse bread in the bowl of a food processor until coarse crumbs are created, about 10 to 12 one-second pulses. Season the salmon with salt and pepper. Set aside.

  2. In a medium bowl, mix together the breadcrumbs, 1 tablespoon butter, both mustards, and thyme, pinching the mixture together so the butter is incorporated and the mixture sticks together. Season with salt and pepper.

  3. Spread the bottom of each fillet of salmon with a thin layer of butter. Preheat a medium skillet over medium-high heat for 2 minutes. Add salmon buttered-side down and cook without moving until a nice crust has formed, about 2 minutes. Pile the crumbs on the salmon, then transfer to the broiler. Broil until the crumbs are crunchy and browned, 4 to 5 minutes. Serve immediately.
