It’s a worthy successor to smashed avocado yet seasonal, sustainable and morally uncompromising: Brussels sprouts on toast!

Who invented avocado on toast?
If you wondered who first came up with the idea to put mashed-up plants on toast and charge fifteen quid for it, blame (or perhaps don’t, since he very sadly passed away in 2025) the Australian chef Bill Granger. In the 1990s Sydney, Bill first introduced ‘smashed avo’ in his restaurant. But it was in the 2010s that the dish (if you will call it that) spread like a wildfire in trendy cafés and on social media of the US and Britain.
It is a very nice thing to have for breakfast or brunch, though there are some ethical issues related to avocados. It’s the usual suspects: there’s the environmental damage including deforestation, high water usage and carbon footprint left by the avos flown across the world. Its cultivation in deprived regions questionably involves child labour and exploitation. And that’s all before we consider the hazard of ‘avocado hand’ injuries at home!
Beyond avocado
All the risks mean café owners and chefs have started looking around to find a sustainable and noble replacement to smash and pile on toast. Those include peas or broad beans, both very fitting replacements in my view. Other beans have not taken off so much, perhaps due to not being green. I also do like a slightly more different version, which is strawberries and ricotta on toast. Still, the colours are wrong.
Hummus or mushrooms are very nice but old news and far removed from avo. And thus my proposition is a sure winner, being seasonal, cheap, sustainable, local, green and morally unambiguous: good old Brussels sprouts!
How to cook sprouts for the toast
Preparation does take a bit longer than to peel an avocado but it’s injury risk-free and really simple.
The sprouts, trimmed and washed, halved if enormous specimens, need to be seasoned very well with salt and black pepper, then drizzled generously with olive oil. No need for expensive extra virgin: decent quality standard olive oil will suffice. Massage the seasoning into the sprouts and turn them all out onto a roasting tray.
After about forty minutes they will be wonderfully crisp-charred on the outside and soft in the middle. To ensure they cook and crispen evenly, give the tray a shake once or twice whilst roasting.
Toast the bread, thickly sliced sourdough recommended, when the sprouts are almost ready to come out, but there’s no need to butter it thanks to the olive oil used for the sprouts.
Mashy-smashy
You can mash the sprouts gently in the tray, then spread them on toasted slices. If they are very soft and the bread sturdy, pile them on and smash with a fork on the toast. That will make sure the oil and juices flavour the bread.
Don’t discard the crispy, blackened bits! Unless you left the sprouts in the oven for much too long and they have turned bitter, those will be the nicest bits, scattered all over. A sprinkling of flaky salt, and a few gratings of Parmesan and your brunch/breakfast/snack is ready to tuck in.
They are really delicious on toast – and so says I, no great lover of sprouts. Wholesome and comforting, the textures are lovely and the whole thing tastes like good autumnal or wintry fare – which no avocados can ever do.
Mushroom option
My recipe includes mushrooms: a few chestnut closed cap champignons will go incredibly well with the sprouts. For that, add them whole or halved in with the sprouts, aiming for same sized chunks. Mushrooms will shrink considerably and obviously they are not smashable, but provide a very nice variety of textures.
Other options
Instead of mushrooms, try diced chunks of butternut or acorn squash. Another idea that will work well is diced celeriac or sweet potato. In both latter cases you might consider adding a touch of mixed dried herbs to the seasoning, as the squashes and the roots are somewhat bland.
