Brussels sprouts have quite the reputation: too bitter, too pungent, the stuff that gets left on the plate. But what if the real problem isn't the vegetable — or your taste buds — but simply how it's cooked? An old kitchen trick, rediscovered in a vintage cookbook, promises to change everything, using an ingredient you already have at home: bread.
Why do Brussels sprouts have such a bad reputation?
Let's be honest: few vegetables divide opinion quite like this one. Yet young, fresh, properly cooked Brussels sprouts can be surprisingly mild. The real culprit behind their image is often the cooking itself — too long, too much water, leaving plenty of room for the strongest flavours to take over.
Like cabbage, broccoli and cauliflower, Brussels sprouts belong to the cruciferous family. They naturally contain sulphur compounds called glucosinolates, responsible both for their slight bitterness and their recognisable smell. When the sprouts are cut, chewed or heated, these compounds break down and release different aromas — and the longer the cooking, the more the sulphurous smell tends to take over.
The rediscovered secret: a ball of bread in the cooking water
In an old cookbook, one method stood out as both simple and unexpected: cook the sprouts alongside a large ball of white bread, tied up in a small cloth bag, right in the same water. The bread acts as a sponge for odours throughout the cooking. Once the sprouts are ready, the bag is removed and thrown away — job done.
According to the original author, the bread ended up smelling "dreadful", while the sprouts gained a noticeably milder flavour. That's exactly the kind of forgotten trick worth dusting off.
Good to know
Bread has a porous structure that soaks up water and odours well. Similar tricks are still used today to soften the smell of broccoli, cauliflower and other cruciferous vegetables while cooking.
Step by step: how to try it
Brussels Sprouts with the Bread Trick
Cooking time 5–8 minutes · Old-fashioned trick
What you'll need
- Brussels sprouts
- A large ball of white bread (about the size of an apple)
- A small piece of clean cloth or muslin
- Kitchen string
- A large pot of water
- Salt
Method
- Clean the sprouts: remove any damaged outer leaves and trim the base. Halve the larger ones for more even cooking.
- Shape the bread into a ball, place it in the centre of the cloth, and tie it into a small, secure bundle.
- Bring a large pot of salted water to the boil.
- Drop the sprouts and the bread bag into the boiling water together.
- Cook for 5 to 8 minutes, until the sprouts are tender but still slightly firm.
- Remove the bag immediately and drain the sprouts. The bread goes straight to the compost.
Does it actually work?
Bread does genuinely absorb some of the strongest cooking odours — that much is a well-known principle. It's harder to claim, though, that it removes all the bitterness from the sprouts: that also depends on the variety, freshness, size, cooking time and amount of water used. Glucosinolates and their breakdown products do play a real role in that characteristic bitterness.
Cooking time still matters most
Even with the bread bag in, Brussels sprouts shouldn't be left to boil endlessly: overcooking intensifies the sulphurous smell and leaves an unappetising, mushy texture. Five to eight minutes is usually enough, depending on size — a knife tip should slide in easily without the sprout falling apart.
Once blanched, sprouts are endlessly versatile: pan-fried in butter, tossed with bacon, served with hazelnuts or chestnuts, gratinated, finished with a little mustard or vinegar — or even preserved for later. A quick second pass in the pan also lightly browns them and softens the flavour even further.
"The bread bag isn't magic, but it might just be enough to win someone over to Brussels sprouts — and that's no small thing."
Are today's sprouts already milder?
Often, yes. Bitterness naturally varies from one variety to another, and plant breeders have worked on milder varieties than some of the older ones. That might explain why certain old recipes seem overly elaborate today: they were designed for far stronger vegetables than the ones typically found in shops now. But even with modern varieties, overcooking remains the surest way to ruin a Brussels sprout.
The bread bag trick remains a fun, down-to-earth experiment worth trying. And if it helps win someone over to Brussels sprouts, that old cookbook won't have been dusted off for nothing.
