Maple-Roasted Brussels Sprouts
To roast Brussels sprouts, halve them, toss with oil and salt, and spread cut-side down in a single layer on a hot baking sheet. Roast at 220 °C for 20 to 25 minutes without stirring, so the flat sides caramelize. Toss with maple syrup and crisp bacon in the last few minutes. High heat and an uncrowded pan are what separate sweet, nutty sprouts from soggy, sulphurous ones.
Brussels sprouts have spent decades paying for the sins of a previous generation’s cooking. Boiled or steamed into grey submission, they genuinely are unpleasant — soft, sulphurous, faintly bitter. Roasted hard in a hot oven, they become something else entirely: nutty, sweet, crisp at the edges, and one of the best things on an autumn table.
The recipe below is barely a recipe. It’s a technique with a maple glaze on the end.
The pan is the whole thing
If you take one instruction from this page, make it this: do not crowd the pan. Sprouts release a surprising amount of water. Piled together, that water can’t escape, so they steam in it — and steamed sprouts are exactly the sprouts everyone remembers hating.
Give them room. A single layer with visible gaps between them. If your 700 g don’t fit on one sheet with space to spare, use two. An extra pan to wash is a small price for the difference between caramelized and soggy.
Preheating the sheet is the second half of it. Cold metal has to warm up before browning starts, and by then the sprouts have already begun releasing moisture. A screaming-hot pan sears the cut face immediately.
Cut-side down, and leave them alone
Lay every sprout with its flat face against the metal. That face is where the deep, even browning happens, and it only happens through sustained contact.
Then resist stirring. Every toss interrupts the browning and puts a fresh cold face on the pan. Twenty-plus minutes of undisturbed contact is what builds that mahogany crust. The loose outer leaves that fall off will go almost black and turn into crisps — those are the best part, so don’t pick them out.
The glaze goes on at the end
Maple syrup added before roasting will burn long before the sprouts are cooked. Sugar and a 220 °C oven are not friends over twenty-five minutes.
So roast them plain, and toss with the maple, vinegar and bacon once they’re out. The residual heat is enough to make the syrup cling and gloss without scorching it. The splash of cider vinegar isn’t optional in spirit — maple alone reads as flatly sweet, and the acid is what makes the whole thing taste balanced rather than like dessert.
Make it yours
Bacon is the classic partner but far from the only one. Try:
- Nuts instead of bacon — toasted pecans or walnuts, for a vegetarian version with the same richness.
- A sharper finish — crumbled blue cheese or shaved parmesan over the top while hot.
- Fruit — a handful of dried cranberries tossed in at the end, which is very good alongside roast poultry.
- Heat — a pinch of chili flakes in the oil before roasting.
Leftovers are decent cold, chopped into a grain bowl the next day, though they lose their crispness in the fridge. They’re best eaten within a few minutes of leaving the oven, which is rarely a difficult rule to follow.

Instructions
- Heat the oven to 220 °C with the baking sheet inside. A preheated pan starts the browning the moment the sprouts land.
- Trim the stem ends and pull off any loose or yellowed outer leaves. Halve each sprout through the stem.
- Toss the sprouts with the oil, salt, and pepper until evenly coated.
- Pull out the hot sheet and spread the sprouts cut-side down in a single layer, with space between them. Use two pans rather than crowding one.
- Roast 20–25 minutes without stirring. The cut faces should be deep brown and the loose leaves nearly black and crisp.
- If using bacon, fry it separately until crisp while the sprouts roast, and drain.
- Toss the hot sprouts with the maple syrup, vinegar, bacon, and nuts. Taste for salt and serve straight away.
Frequently asked questions
Why do my Brussels sprouts taste bitter or sulphurous?
Almost always because they were steamed rather than roasted. Crowding the pan traps moisture, and sprouts cooked slowly in their own steam turn soft and release the sulphur compounds people associate with hating them. Dry roasting at high heat does the opposite — it caramelizes the outer leaves and turns them nutty and sweet. Use a big pan, leave space between the sprouts, and don't cover them.
Should I cut them in half or leave them whole?
Halve them. A cut face laid flat against a hot pan is where all the browning happens, and a whole sprout gives you none of that while taking longer to cook through. For very large sprouts, quarter them. Very small ones can stay whole if you're happy with less caramelization.
Is it true they taste better after a frost?
Yes, and it's the reason sprouts are a late-season crop worth waiting for. Cold weather prompts the plant to convert some of its starches to sugars, so sprouts picked after the first frosts taste noticeably sweeter and less sharp. If you're buying rather than growing, October and November sprouts are usually the best of the year.
