Author Notes
A mandoline is crucial here. (You could shave the sprouts with a knife, but they'll be less thin, less even, and more time-consuming.) Make the dressing in advance, if that works better with your schedule. Just store in the fridge and gently rewarm, to liquify, before dressing; you want it runny but not hot. —Emma Laperruque

Ingredients
-
1 pound
Brussels sprouts
-
1 pinch
kosher salt
-
6 tablespoons
chopped, toasted walnuts, divided, plus more for topping
-
2 tablespoons
unsalted butter
-
1/2
small shallot
-
1 1/2 teaspoons
Dijon mustard
-
1 tablespoon
sherry vinegar or apple cider vinegar
-
1 1/2 teaspoons
water
-
1/4 cup
grated pecorino, plus more for topping
-

Directions
-
Shave the Brussels sprouts on a mandoline into a large bowl. Season with a big pinch of salt and toss. While that rests, make the dressing.
-
Put 2 tablespoons walnuts in a heatproof bowl. Add the butter to a small skillet and set on the stove over medium heat. Melt until it browns, 2 to 3 minutes. Immediately pour it over the walnuts. Leave that to cool for a moment while you combine the shallot, Dijon, vinegar, and water in a food processor or blender. Pulse to combine, scraping down as needed, until as smooth as possible. Add the walnuts and brown butter and process until smooth.
-
Add the dressing to the salted sprouts, plus the remaining walnuts and pecorino. Toss. Top with more nuts and cheese and some freshly ground black pepper.
