Roasting the vegetables concentrates and sweetens their flavor. However, you can simplify the dish even further by steaming the vegetables instead. Whether you steam or roast, make sure not to overcook the vegetables; they are best when they retain a little crunch. If you don’t have access to beautiful Romanesco broccoli, regular broccoli can be substituted.

Mustard Caper Butter:
2 garlic cloves
1/4-1/2 tsp. salt
3 Tbsp. chopped thyme
1/4 cup drained small capers, rinsed
1 Tbsp. finely grated lemon peel
Freshly ground black pepper
6 Tbsp. butter, softened
1 Tbsp. Dijon mustard

Vegetables:
1 stalk (or 1 pound) Brussels sprouts
1 small head Romanesco or regular broccoli
1 small head white cauliflower
2 Tbsp. olive oil
Salt
Freshly ground black pepper

Preheat the oven to 450°F.

Make the Mustard-Caper Butter: Pound the garlic with 1/4 tsp. salt in a mortar until smooth. Pound the thyme, capers, lemon peel, and freshly ground black pepper into the garlic. Pound in the butter and mustard, making sure the other ingredients are evenly distributed in the butter. You can also mix the butter in a food processor. If you do, add the capers only after the other ingredients are thoroughly combined and pulse in the capers so they stay a little chunky. (The butter can be made ahead, refrigerated, and brought to room temperature before serving.)

Cook the Vegetables: Snap the Brussels sprouts off the stalk, trim off their tough base, and slice them in half. Bring a large pot of salted water to a boil. Add the Brussels sprouts and cook for 3 minutes. Drain and rinse with very cold water. Cut the cauliflower and Romanesco broccoli into florets. Put the vegetables, including the drained Brussels sprouts, on a rimmed baking sheet and toss with olive oil and a light sprinkling of salt and freshly ground black pepper. Bake for 10 minutes.

Finish the Dish: Put the roasted vegetables in a bowl and toss with the Mustard-Caper Butter until it melts and coats the vegetables. Taste and add salt or freshly ground black pepper, as needed.
