When cooking brussels sprouts, my go-to method is caramelizing them as much as possible. Often, I just start them cut-side down in a cast iron skillet until golden, then finish them in a blazing hot oven with a splash of balsamic vinegar. But that's not the only way to dress them up.
Who can argue with Nigel Slater's brussels sprouts technique, especially when he suggests a recipe as decadent as this one? Robed in a sauce of cream, blue cheese, and whole grain mustard, they're cooked down gratin-style under a blanket of Parmesan. It's the richest thing I've eaten in ages, and it took all my will to not slurp it up with a straw.
To make this into a main dish, toss it with cooked pasta.
