Miso-Maple Brown Butter Brussels Sprouts

Mon, 25 May 2026 00:00:00 -0400

Roasted Brussels sprouts glazed in nutty brown butter, white miso, and maple syrup, finished with toasted sesame and scallion. Deeply savory and sweet with the bitter edge of well-charred sprouts cutting through the richness.

Serves 4 generously as a side, or 2 as a vegetable-forward main with a starch alongside. No salt is added anywhere — the miso brings plenty.

Ingredients

For the Sprouts

800g (1¾ lb) Brussels sprouts, trimmed (about 980g untrimmed), halved lengthwise; quarter any larger than a walnut
2 tbsp neutral oil or olive oil
Black pepper, generous

For the Glaze

45g (1½oz) unsalted butter (3 tbsp)
30g (1oz) white or yellow miso (shiro or saikyo; reduce to 22g if using red)
40g (2 tbsp) maple syrup, Grade A dark
1 tbsp rice vinegar (apple cider vinegar works too)
1–2 tsp warm water, only if needed to loosen

For the Finish

1–2 tsp toasted sesame seeds (white, black, or mixed)
1–2 tsp furikake (optional, in addition to or instead of sesame)
1–2 scallions, greens thinly sliced on a bias

Equipment

Quarter or half sheet pan
Small saucepan (a light-colored interior helps you see the butter browning)
Small bowl and whisk for the glaze
Tongs or a spatula

Instructions

Prep the Sprouts

Heat the oven to 425°F (220°C).
Trim the stem ends of the sprouts and pull off any loose or browned outer leaves. Halve each sprout lengthwise through the stem. Quarter any that are larger than a walnut. Loose leaves that fall off go on the pan too — they crisp into chip-like bits.
Toss the sprouts with the oil and a generous amount of black pepper in a bowl. No salt yet. Arrange them cut-side down in a single layer on the sheet pan. Crowding leads to steaming — use two pans if needed.

Make the Brown Butter Glaze

While the oven heats, melt the butter in a small saucepan over medium heat, swirling the pan. It will melt (~30 seconds), foam loudly as water cooks off (1–2 minutes), quiet down as the foam subsides, then turn deep amber with toasted milk solids settling on the bottom (~30 seconds after the foam subsides) and smell unmistakably nutty.
Pull off the heat the moment you smell hazelnut. Brown butter goes from nutty to burnt in under a minute at the end — trust your nose and pull early. Pour into a small bowl, including all the brown bits, to stop the carryover cooking.
Whisk the miso, maple syrup, and vinegar into the warm brown butter until smooth and glossy. If it seizes or feels too thick to pour, whisk in warm water a teaspoon at a time until it ribbons off the whisk.

Roast

Slide the sprouts into the oven and roast 20 minutes, undisturbed. Do not toss or shake — you want the cut faces to develop deep brown caramelization. The tops will look a little tired and steamed; the bottoms are where the magic is happening.
Check at 20 minutes by lifting one with tongs. The cut face should be deeply browned, near black at the edges of the leaves. If they’re still pale, give them another 3–5 minutes.

Glaze and Finish

Pull the pan. Pour about three-quarters of the glaze over the sprouts and toss directly on the sheet pan with tongs until every sprout is coated. Reserve the rest for plating.
Return to the oven for 3–5 minutes to let the glaze tighten and caramelize. Miso scorches fast once it’s on the sprouts — set a timer for 3 minutes and check. You want the glaze tacky and clinging, not blackened.
Slide onto a serving plate or shallow bowl. Drizzle with the reserved glaze. Scatter sesame seeds, furikake, and scallion greens over the top. Serve immediately.

Notes

On miso choice. White (shiro) miso is sweet and mellow — the easiest match for the maple. Yellow (shinshu) is more assertive and works just as well. Red (aka) miso is salty and funky enough that you should drop the amount by about 25% and consider adding an extra splash of maple to balance. Avoid hatcho or other very dark misos — they overpower the sprouts.
On the vinegar. Not optional — without it the glaze tastes flat and one-note sweet-salty. Rice vinegar is cleanest; cider vinegar leans the dish slightly autumnal. Avoid balsamic (too sweet, too dark) and white vinegar (too harsh).
On the maple. Real maple, not pancake syrup. Grade A dark / Grade B has more character and stands up better to the miso. In a pinch, honey works but reads sweeter — back it off to about 30g.
On serving size. 800g of trimmed sprouts is genuinely a lot. It serves four generously as a side. As a vegetable-forward main, it serves two with a starch alongside — rice, smashed potatoes, or crusty bread.

Variations

Add nuts. Toasted chopped pecans, walnuts, or hazelnuts scattered with the sesame add textural contrast and echo the brown butter.
Add fruit. A small handful of pomegranate arils or dried cranberries (rehydrated briefly in warm water) at the finish brings acid and color. Good for a holiday table.
Vegan. Substitute a good neutral vegan butter (Miyoko’s, Country Crock plant) for the dairy butter — it browns less dramatically but still develops nutty notes. Or use 2 tbsp toasted sesame oil whisked into the glaze in place of the brown butter for a different (still excellent) direction.
Ginger and garlic. Whisk 1 tsp finely grated fresh ginger and 1 small clove of grated garlic into the glaze for a more aggressive East Asian profile.
With shallots. Thinly slice a small shallot and scatter raw over the finished sprouts along with the scallions for a sharp counterpoint to the sweet glaze.

Storage

Make-ahead. The glaze holds for a few days in the fridge — gently rewarm before using; it solidifies cold. Sprouts are best roasted just before serving and lose their crispness within an hour.
Leftovers. Reheat in a dry skillet over medium-high heat, not the microwave — microwaving destroys the crust. They make a great folded-into-fried-rice ingredient the next day.
