Do not overfill sheet
If the Brussels sprouts is on top of each other, it dampens in its own water vapour. Spread on two sheets when the surface becomes scarce.
High heat and sufficient distance on the sheet ensure browned cutting surfaces. A sour mustard glaze keeps the sweetness in balance.
Why this recipe works
Brussels sprouts is particularly aromatic in the oven when the half-shaped skirts with the cut surface lie on a hot sheet. Use a large sheet and distribute everything in just one layer. Walnuts roast significantly faster than the vegetables and are therefore only added in the last minutes.
Recipe
Brussels sprouts roast with red onion, mustard and maple syrup; walnuts added near the end stay crisp and aromatic.
Preheat the oven to 220 °C top/bottom heat and heat up a large, empty sheet in the oven.
Remove Welke's outer leaves, cut off the stunk and halve the florets. Very large specimens quarter.
Mix olive oil, mustard, maple syrup, salt and pepper. Mix Brussels sprouts and onion splits thoroughly with the mixture.
Gently spread vegetables on the hot sheet. Roast Brussels sprouts with the cut surface down for 18 minutes.
Spread Walnuts and thyme on the sheet and roast for another 5 to 7 minutes. Drizzle with apple vinegar and serve immediately.
