Okonomiyaki Brussels Sprouts

Step 1

Arrange oven racks in top and lower thirds of oven. Place one rimmed baking sheet on top rack and another on bottom rack; preheat to 450°. Toss brussels sprouts and oil in a large bowl; season with salt. Carefully remove one hot pan from oven and transfer half of sprouts to pan—they’ll sizzle! Working quickly, turn sprouts cut sides down (don't worry if you can't get to all of them; it doesn't have to be perfect!). Repeat with second pan and remaining sprouts. Roast brussels sprouts, rotating pans halfway through, until cut sides are seared and tops are browned, 15–20 minutes.

Step 2

Meanwhile, mix Worcestershire sauce, ketchup, honey, vinegar, ginger, and ½ tsp. shichimi togarashi in a small pot. Bring to a simmer over medium-high heat, then reduce heat to medium-low and gently simmer, stirring frequently, until thickened and glazy, 3–4 minutes. Taste and season with salt.

Step 3

Pour glaze over brussels sprouts and toss to coat. Transfer to a platter. Sprinkle with nori, then squeeze mayonnaise over in stripes, covering the whole dish (trust us!). Pile bonito flakes in the center of the sprouts. Top with sesame seeds, scallions, and a dusting of togarashi.
