How to make the best honey roasted parsnips and carrots?
Ingredients list
Jamie Oliver’s honey roasted carrots and parsnips recipe uses 600g carrots peeled and cut into chunky batons alongside 600g parsnips, peeled, cored, and cut into similar-sized pieces (jamieolivereats.uk). The coating relies on 3 tablespoons of olive oil or vegetable oil and 2 tablespoons of runny honey for caramelisation. Recipes from his official site also call for bay leaves, balsamic vinegar, and fresh thyme to build depth of flavour.
Step-by-step roasting method
- Preheat your oven to 200°C (400°F) for immediate caramelisation.
- Toss the prepared vegetables in the oil, honey, and any seasoning until evenly coated.
- Spread them in a single layer on a roasting tray.
- Roast for 40–45 minutes, turning once halfway through, until the edges are golden and the glaze has set into a glossy finish (jamieolivereats.uk).
High oven temperature is non-negotiable for deep caramelisation—resist dropping it even if your oven runs hot.
Coating mixture tips
- Mix oil, honey, mustard, and a splash of vinegar before tossing
- Ensure vegetables are dry before coating for better adhesion
- Apply in a single layer on the tray for proper air circulation
- Add optional flavour boosters—mustard seeds, balsamic, chilli flakes, or orange zest—in the final 10–15 minutes
Do I need to parboil carrots and parsnips before roasting?
Parboiling benefits
Some recipes parboil parsnips whole for 5 minutes in boiling salted water before roasting. This step partially cooks the denser parsnip flesh, ensuring the interior becomes tender while the exterior caramelizes without burning. After parboiling, steam dry the vegetables before tossing them in oil (jamieoliver.com).
Direct roast alternative
The primary honey roasted carrots and parsnips recipe uses no parboiling at all. Cut the vegetables into even-sized batons, toss directly in the honey-oil mixture, and roast at 400°F. This approach saves time and delivers a sweeter, more concentrated flavour since no sugars leach out during boiling.
When to skip
The BBC recipe marks parboiling as optional, noting that it works best when you’re cooking for a crowd and want guaranteed tenderness throughout. For weeknight dinners with smaller portions, skip the step—the shorter 40–45 minute roast handles evenly cut vegetables without issue.
Parboiling is a holiday prep technique rather than a weeknight necessity, which is why Jamie Oliver specifically suggests parboiling on Christmas Eve and roasting the next day.
How does Jamie Oliver make honey roast parsnips?
Secret ingredient
Jamie Oliver’s roasted parsnips recipe adds bay, vinegar, and honey during the final 10 minutes of cooking rather than at the start. This technique builds layers of flavour—the vinegar adds acidity that cuts through the sweetness, and the late honey addition creates a lacquered finish rather than a heavy glaze. As his site notes, “this is Jamie’s favourite way to cook Christmas veg.”
His roasting technique
His “Really Good Roast Veg” recipe combines 1kg carrots and 1kg parsnips at 180°C/350°F/gas 4 for 1 hour 20 minutes. The lower temperature and longer cook time allow the natural sugars to develop more slowly, resulting in deeply caramelized edges without the urgency of a high-heat method.
Adapt for carrots
When adapting his parsnip techniques for carrots, keep the sizing consistent—chunky batons roast more evenly than thin slices. Add carrots in the last 20 minutes if roasting alongside parsnips, since carrots generally require less time to reach tender-crisp perfection.
Jamie Oliver’s “squash them” trick for parsnips creates the crispiest outsides by increasing surface area in contact with the pan. Applying this to carrots means cutting them into thicker, flatter pieces rather than round coins—flat surfaces crisp better than curved edges.
Do you put honey on carrots before or after roasting?
Before roasting glaze
Apply the honey coating before roasting. The high oven temperature causes the honey to caramelize directly onto the vegetable surface, creating that signature glossy glaze. Adding honey after roasting results in a sticky layer that sits on top rather than integrating into the flesh.
Post-roast touch
Some cooks add a drizzle of honey or balsamic reduction immediately after removing the tray from the oven for extra shine, but this is decorative rather than transformative. The foundational glaze forms during cooking.
Best practice
Toss vegetables in honey and oil before spreading on the tray. Roast at 400°F (200°C) until tender. Reserve any additional glaze or finishing sauce for the final 2 minutes of cooking or for serving.
Apply honey before, not after—the oven does the work of transforming sugar into glaze.
How long do honey roast carrots and parsnips take?
Total cook time
Two main approaches exist. The direct-roast method requires 40–45 minutes at 400°F, with 15 minutes of prep and a total of 55 minutes from start to plate. The parboil-then-roast method runs closer to 1 hour 20 minutes at 180°C, making it better suited for relaxed Sunday roasts than weeknight dinners.
Prep duration
Peeling and cutting 600g of carrots and 600g of parsnips takes roughly 10–15 minutes for an average home cook. If parboiling, add 5 minutes of boiling time plus draining and drying.
Check for doneness
The vegetables are ready when a fork slides through the thickest piece with light resistance—tender but not mushy. The honey glaze should appear golden-brown with slightly darkened edges. For a different take on baked vegetables, consider this air fryer baked potato recipe. Air fryer baked potato recipe
- Direct roast: 40–45 minutes at 400°F
- Parboil then roast: 5 minutes parboil + 1 hour 15 minutes at 350°F
- Combined method (Really Good Roast Veg): 1 hour 20 minutes at 350°F
Higher temperatures shorten cooking time but require closer attention—walk away at your peril.
The natural sweetness of carrots and parsnips intensifies in the oven, while a light coating of honey encourages deep caramelisation and a glossy finish.

Jamie Oliver’s “squash them” trick works on parsnips because flattening increases surface area. Carrots respond the same way—thicker, flatter cuts yield crispier results than round coins.
For home cooks looking for maximum flexibility, the choice between methods comes down to schedule: the direct-roast wins for weeknight speed, while the parboil approach delivers foolproof tenderness for entertaining.

Frequently asked questions
Do you need oil for honey roast parsnips?
Yes. Oil carries the honey onto the vegetable surface and prevents sticking. Without it, the honey burns before the parsnips caramelize. Olive oil or vegetable oil both work.
What’s the secret to perfectly glazed carrots?
Apply the honey coating before roasting, not after. A hot oven (400°F) caramelizes the sugars directly onto the surface, creating that signature glossy finish. Toss in a single layer for even browning.
Can you make honey roasted carrots and parsnips in air fryer?
Yes. Reduce temperature to 350°F and cook for 15–20 minutes, shaking halfway through. The shorter cooking time and contained heat often produce crispier results with less oil.
How to honey roast carrots and parsnips slow cooker?
Slow cookers are not ideal for this dish—the lack of dry heat prevents caramelisation. If you must use one, toss vegetables in coating first, cook on low for 4–6 hours, then finish under the broiler for 5 minutes to develop the glaze.
Do honey roasted carrots and parsnips need balsamic?
Not required, but balsamic vinegar adds depth by cutting through sweetness. Add a splash to the coating mixture or drizzle over the finished dish for a tangy finish.
Should you parboil for air fryer version?
Parboiling is unnecessary for air fryer preparation. The contained circulating heat achieves even caramelisation without pre-cooking. Simply toss in honey and oil, then air fry at 350°F for 15–20 minutes.
How do you store and reheat leftovers?
Store in an airtight container for up to 3 days. Reheat in an oven at 190°C for 10–15 minutes, or in an air fryer for 5–8 minutes. Avoid microwaving, which makes the glaze sticky rather than crispy.
