In a small bowl, whisk together the miso paste, rice vinegar, maple syrup, and sesame oil. Ensure the ingredients blend into a smooth mixture. This glaze will serve as the flavorful crown to our Brussels sprouts.
Preheat your oven to 400°F (200°C). This temperature is essential for achieving that delightful caramelization on the Brussels sprouts.
Wash and trim the Brussels sprouts. Halve or quarter them based on their size. In a large bowl, toss the sprouts with 2 teaspoons of avocado oil, salt, and pepper. The oil helps with roasting and ensures they achieve that desirable crispiness.
Now, add the whole garlic cloves to the bowl. Smash them slightly to release their flavor. This addition adds an aromatic punch that elevates the dish immensely.
Spread the Brussels sprouts and garlic evenly on a baking sheet lined with parchment paper. This makes for easier clean-up later. Roast them in the preheated oven for about 20-25 minutes, or until the sprouts are golden brown and tender. Halfway through, give them a toss to ensure an even roast.
Once the Brussels sprouts are roasted, remove them from the oven and drizzle the miso glaze over them. Toss everything together to coat evenly. Return to the oven for an additional 5 minutes. This extra time allows the glaze to caramelize and intensify flavors.
After the final roast, remove the sprouts from the oven. Sprinkle lemon zest over them, adding brightness to the dish. Your Nobu-style Brussels sprouts are now ready to be served!
