Why This Recipe Works

Traditional roasting is great, but the addition of a miso glaze adds umami—the savory “fifth taste.” By roasting the sprouts at a high temperature first and adding the glaze at the very end, we achieve a crispy exterior without burning the sugars in the syrup and miso.

Ingredients

• Brussels Sprouts: 1.5 lbs, trimmed and halved.
• Olive Oil or Avocado Oil: 2 tablespoons (for roasting).
• White Miso Paste: 2 tablespoons (Shiro miso is preferred for its mild sweetness).
• Pure Maple Syrup: 1.5 tablespoons.
• Rice Vinegar: 1 tablespoon (adds essential acidity).
• Soy Sauce or Tamari: 1 teaspoon.
• Red Pepper Flakes: ½ teaspoon (optional, for a subtle heat).
• Garnish: Toasted sesame seeds or thinly sliced scallions.

Step-by-Step Instructions

1. Prep the Oven: Preheat your oven to 425°F (220°C). Place a large rimmed baking sheet inside while the oven heats; a hot pan helps sear the sprouts instantly.
2. Season the Sprouts: In a large bowl, toss the halved Brussels sprouts with the oil, a pinch of salt, and cracked black pepper. Note: Miso is salty, so go light on the initial salt.
3. The First Roast: Carefully spread the sprouts onto the preheated baking sheet, flat-side down. Roast for 15–20 minutes until the bottoms are deep golden brown and the outer leaves are crispy.
4. Whisk the Glaze: While the sprouts roast, whisk together the miso paste, maple syrup, rice vinegar, soy sauce, and red pepper flakes in a small bowl until smooth.
5. Glaze and Finish: Remove the tray from the oven. Pour the glaze over the sprouts and toss quickly with a spatula to coat. Return to the oven for another 5 minutes. Watch closely—the sugars can burn quickly!
6. Serve: Transfer to a serving bowl and garnish with sesame seeds. Serve immediately for maximum crispness.

Fact-Check: Science & Nutrition

Is white miso better than red? Yes, for this recipe. White miso (Shiro) is fermented for a shorter time with more rice, making it sweeter and less pungent than the longer-fermented red miso (Aka). It complements the maple syrup without overpowering the sprouts.

Why were sprouts bitter in the past? Old-school boiling releases sulfur compounds that create a bitter taste. Roasting at high heat triggers the Maillard reaction, which converts the vegetable’s natural starches into sugars, resulting in a nutty, sweet profile.

Nutritional Punch: Brussels sprouts are cruciferous powerhouses, high in Vitamin K (bone health) and Vitamin C (immune support), while miso provides a small boost of beneficial probiotics.
