Roasted brussels are one thing, but throw on some of the incredible okonomiyaki sauce and wow they're the best thing since sliced bread. If you're wondering, this sauce has like a sweet-acidic-salty-gingery punch that makes Worcestershire sauce a complete condiment, and don't pass up on the kewpie mayo. This dish is dope and a table pleaser with the dancing of the bonito flakes.
- 2 lb. brussels sprouts, trimmed, halved lengthwise
- 2 Tbsp. extra-virgin olive oil
- Kosher salt
- ¼ cup Worcestershire sauce
- 2 Tbsp. plus 1½ tsp. ketchup
- 2 Tbsp. honey
- 2 Tbsp. unseasoned rice vinegar
- 1 tsp. finely grated peeled ginger (from one 1" piece)
- ½ tsp. shichimi togarashi, plus more for serving
- 1 toasted nori sheet, crushed into confetti-size pieces
- Kewpie mayonnaise (for serving)
- ½ cup bonito flakes
- 1 Tbsp. toasted sesame seeds
- 2 scallions, thinly sliced into rounds
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.
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.
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.
