Autumn vegetables: leek, witloof, celeriac

Informational, not medical advice.

TLDR

Gezond Leven places vegetables at the base of the food triangle: for adults the typical cue is at least 300 g of vegetables a day.
In October, leek, Belgian endive (witloof) and celeriac are fully in season — alongside pumpkin, which I deliberately leave aside here.
I cook them simply: leek in soup or a pan, endive braised or raw, celeriac as mash or oven cubes.
Frozen vegetables stay my backup; seasonal fresh wins for taste and routine visibility.

After a week of pumpkin recipes in my feed, I looked for something else on the shelf. Leek, witloof and celeriac sat there without hype. Cheap, sturdy, and clearly “now” on the seasonal calendar. That became my autumn base without repeating the same soup.

What Gezond Leven says about vegetables

Flanders Institute Gezond Leven puts vegetables in the dark-green zone of the food triangle. The practical cue for adults is often at least 300 g of vegetables a day, preferably varied. The Superior Health Council stays in the same lane: vegetables belong in a stable eating pattern, next to fruit and legumes.

I use those numbers as orientation — not a scoreboard. Just a check: is there visible veg on my plate today?

Why leek, witloof and celeriac in October

On seasonal calendars for our region (Gezond Leven, Brussels Environment and retail calendars), leek, witloof and celeriac are clearly in season in October. They keep well, need little fancy technique, and fill a week’s menu without turning everything orange.

Practically I notice three things. First: leek is the fastest “onion + vegetable” in one. Second: witloof is bitter or mild depending on braising or raw. Third: celeriac adds volume to mash and tray-bakes.

Three preparations I repeat

Leek: wash, rings, 8–10 min with olive oil; or as a base in vegetable soup.
Witloof: braised with a splash of stock; or finely sliced with apple and a handful of nuts.
Celeriac: peel, cubes, oven 25–35 min; or boil and mash.

Frozen vegetables stay my backup. And seasonal fruit — see apples and pears in October — stays separate from this vegetable block.

How I fit them into the week

Monday: leek soup or leek with eggs.
Wednesday: braised witloof with fish or legumes.
Friday: oven celeriac next to a protein.
Leftovers: into weekend soup, not the bin.

Pumpkin can stay on the menu in other weeks; this piece is deliberately the counterpart: vegetables that are less “Instagram orange” but still hit the seasonal calendar.

Limits

More vegetables is not automatically “better” if your gut protests. If you have a prescribed diet, check with a doctor or dietitian.
