Honey-Roasted Parsnips

Published 30 October 2026 · Updated 30 October 2026

Roasted parsnips bring earthy sweetness to the table, with golden cut faces and tender centres beneath a light honey glaze. A brief parboil starts the roots softening, while butter and thyme join the honey near the end so the coating does not spend the whole roast in the oven.

Ingredients

  • Parsnips - 500g

    Parsnips

    500g whole raw parsnips, weighed before peeling and trimming

    One 500g whole-root pack supplies the recipe starting weight; peeling and woody-core removal reduce edible weight. Use all edible prepared roots.

Other Ingredients You'll Need

  • Rapeseed oil — 18ml (All for initial roasting.)
  • Runny honey — 18g (All added late with butter and thyme; none in initial roast.)
  • Unsalted butter — 12g, cut into small cubes (All in late glaze. Contains milk.)
  • Fresh thyme — 1g picked leaves (Discard woody stalks during preparation; all leaves in late glaze.)
  • Fine salt — 6g, divided: 4g for cooking water, 2g for roasting (Discard cooking water; not all salt is consumed.)
  • Ground black pepper — A small pinch (about 0.3g) (All with oil before roasting.)
  • Water — About 1.5 litres cold water, enough to cover roots by 2cm (Parboiling medium only; all drained and discarded. Use larger pan if unsafe headroom.)

Method

Prepare the roots while the oven heats

Heat the oven to 210°C conventional / 190°C fan / gas 6–7. Allow 15 minutes for preheating alongside preparation. Use a shallow metal roasting tin with a usable base at least 30 × 22cm, a 3-litre lidded saucepan, colander, long-handled spoon, dry oven gloves and a heatproof trivet. Scrub, peel and trim the parsnips. Split thick roots lengthways and cut away any hard woody core; cut into wedges roughly 6–8cm long and no more than 2cm thick, leaving short narrow tips in larger pieces so they do not scorch. Use all edible roots from the 500g starting weight, not a promised 500g after trimming. Pick and weigh the thyme leaves, measure the other ingredients and cube the butter. Leave the tin at room temperature: no separate hot-fat stage is needed.

Heat the water and briefly parboil

Put the cut parsnips in the saucepan with about 1.5 litres cold water to cover by 2cm and 4g of the salt. Leave ample headroom. Cover and bring to the boil over high heat, allowing about 8 minutes. Remove the lid, lower to a gentle boil and cook for about 4 minutes. The outsides should just soften while a small knife still meets resistance at the centre; drain sooner if they reach that point. They must hold their shape rather than crumble.

Drain and dry the surfaces

Carefully drain into the colander and discard all the cooking water. Allow 4 minutes in total for draining and uncovered steam-drying, until water stops dripping and the surfaces look matt rather than wet. Do not shake vigorously or mash the softened edges. Give wet roots longer to dry.

Coat and space in the tin

Allow about 2 minutes to put the dry-surfaced parsnips in the unheated metal tin, add all 18ml oil, the remaining 2g salt and all the black pepper, and turn gently to coat. Spread in a single layer with gaps between the pieces, broad cut faces down. Use a larger tin if necessary rather than piling them up. Put on the middle oven shelf once the oven has reached temperature.

Roast before adding sweetness

Roast for 15 minutes, then use dry oven gloves to set the tin on the trivet and turn the wedges with the spoon. Return for a further 12 minutes, including this brief turn in the roasting allowance. The broad faces should be golden in patches and a knife should enter the thickest centre easily before glazing. If still firm, continue roasting unglazed in 5-minute intervals until tender; if colouring too quickly, lower the oven by 10°C and add actual extra cooking time.

Add the honey, butter and thyme late

Set the hot tin securely on the trivet. Allow about 2 minutes to add all the butter cubes, honey and thyme leaves directly to the hot parsnips and turn gently as the butter melts. Coat the roots rather than leaving honey in a bare corner of the tin; no separate hob melting is required. Return to the oven for about 7 minutes until the glaze clings and bubbles lightly, checking after 4 minutes within that allowance. Remove earlier if golden and glossy; do not wait for black edges or a dry, dark coating.

Serve without a holding stage

Allow about 1 minute to lift the glazed parsnips into a shallow serving dish, spooning any lightly golden glaze over them and leaving any burnt deposits behind. Divide into four small side portions and serve straight away, uncovered. There is no planned rest or cooling stage.

Serving Suggestion

Serve beside Roast Poussin with Garlic, Thyme and Lemon, with Garlic Butter Kale for a green accompaniment. These separate dishes have their own ingredients, allergens and timings; plan oven use around their different temperatures. Their preparation is not included here.

Frequently Asked Questions

Why is the honey added near the end?

The parsnips need enough time to soften and brown before their sugary coating goes on. Glazing only when a knife enters the centre easily reduces the time honey spends against hot metal; watch the final roast and stop before the coating blackens.

Do I need to remove every parsnip core?

Only remove a core that feels hard and woody when you cut the root. Smaller roots often need no coring. Trim loss varies, so this recipe uses all edible pieces from the whole starting weight rather than promising a fixed prepared yield.

Why are my roast parsnips pale and wet?

Water left after draining and a crowded tin both encourage steaming. Wait for matt surfaces and arrange one layer with gaps. Do not add the honey to rescue roots that are still wet or firm; finish the unglazed roasting stage first.

Does one 500g amount make four large portions?

No: these are small accompaniments, with peeling and any woody-core removal reducing the edible amount. Serve alongside other vegetables and a main rather than treating four portions as a measured cooked weight.

Can I skip the parboil or replace honey with syrup?

Neither change is covered by this timetable. Raw roots need a different roasting allowance, and a different syrup may colour at a different rate. Follow the stated brief parboil and late honey glaze for this recipe.
