Geroosterde Wintergroenten
Created by
Winter roots are the quiet Dutch pantry at its best: carrot, parsnip, celeriac, and knolraap roasted until their edges darken and their old sweetness remembers itself.

In my grandmother's second notebook, the winter pages are not glamorous. Potatoes. Carrots. Onions. Knolraap, turnip, written in the firm hand of a woman who knew what a cellar had to do by February. The old Dutch kitchen never trusted abundance to last, so it learned the sweetness hidden in roots and bulbs, the kind that waits underground while the weather behaves badly above it.
But let me tell you a secret: this dish is not ancient in its method, only in its ingredients. Dutch cooks boiled and mashed these vegetables for generations because fuel was dear and ovens were not casual Tuesday equipment. The modern baking tray is the luxury here, not the vegetables. Roasting lets the sugars come forward and lets the edges catch, which is exactly what boiling politely refuses to do.
The name doesn't need excavating. Geroosterde wintergroenten means roasted winter vegetables, and for once the Dutch plainness is doing honest work. Cut everything to the same stubborn size, give it oil, salt, thyme, and a little nutmeg if you want the old spice cupboard to nod from the shelf. Hou het altijd simpel, always keep it simple. A hot oven, one tray, and patience enough to turn the roots once. That's the whole education.
Before the potato became dominant in Dutch kitchens in the eighteenth and nineteenth centuries, roots such as parsnip, carrot, turnip, and celeriac were essential winter foods because they stored well through the cold months. Knolraap, the turnip, appears throughout older Dutch household cooking but nearly vanished from everyday use as potatoes and later supermarket habits narrowed the winter vegetable drawer. Roasting these roots together is a modern weeknight method applied to an older Dutch larder: frugal ingredients, made generous by heat and time.
The technique, the tradition, and the story behind every dish.

Equipment Needed
- •Large rimmed baking tray
- •Sharp chef's knife
- •Vegetable peeler
- •Wide spatula
Instructions
- 1
Heat the oven
Heat the oven to 220C. Put a large rimmed baking tray in the oven while it heats. A hot tray gives the vegetables their first proper sizzle, and that first contact matters; otherwise they lounge in their own moisture before they begin to roast.
- 2
Cut the roots
Cut the carrots, parsnips, celeriac, and knolraap into pieces of roughly the same size, about 3cm. This is not for neatness. It is fairness. A small parsnip burns while a large celeriac cube is still thinking about supper.
- 3
Season the tray
Toss the cut vegetables and onion wedges with the oil, apple syrup or honey, salt, pepper, nutmeg, and thyme. The nutmeg should be a whisper, not a sermon; Dutch spice is often like that, present enough to change the room and modest enough not to announce itself.
Use your hands for mixing. Oil finds corners a spoon misses, and roasted roots punish dry patches with toughness. - 4
Roast hard
Carefully tip everything onto the hot tray and spread it in a single layer. Roast for 25 minutes without fussing. The vegetables need contact with the metal and enough space around them; crowd the tray and you have made boiled vegetables in disguise.
- 5
Turn and finish
Turn the vegetables with a spatula, scraping up any browned edges, then roast for another 12 to 15 minutes. They are ready when the carrot bends under the fork, the celeriac is creamy inside, and the parsnip edges have gone deep gold with a few darker freckles.
- 6
Brighten and serve
Splash the hot vegetables with the apple cider vinegar and toss once more. Taste before you serve; roots are sweet, and the vinegar wakes them up. Scatter with parsley if you like, then bring the tray or a warm dish straight to the table.
Chef Tips
- •The tide sets the menu, and so does the calendar. Make this with true winter roots: carrot, parsnip, celeriac, turnip, swede, beetroot, or small potatoes. Courgette in January has travelled too far and tastes tired.
- •If you cannot find knolraap, use swede or extra celeriac. Substitute the ingredient, never the standard: you want a firm winter vegetable that can take heat without collapsing.
- •Do not skip the vinegar at the end. It is a small Dutch kitchen lesson: sweetness needs a little sourness beside it, the way apple syrup wants cheese and herring wants onion.
Advance Preparation
- •The vegetables can be peeled and cut up to 24 hours ahead; keep them covered in the refrigerator, with the parsnips and celeriac in cold water to prevent browning, then dry very well before roasting.
- •Leftovers keep for three days refrigerated and reheat best on a hot tray at 200C for 10 to 12 minutes.
