Roasted carrots with thyme are an easy oven side dish that turns a humble bag of root vegetables into something seriously good in under an hour. This simple roasted carrots recipe needs five everyday ingredients and gives you tender, golden pieces with caramelised edges every single time.
The roasted carrots come out soft and naturally sweet through the middle, with brown crispy edges. Fresh thyme leaves bring an earthy, gently woody note that suits the sweetness of the carrots without taking over.
You only need a baking tray, a sharp knife and a hot oven, so it works just as well for a midweek dinner as it does for a holiday side. Prep takes ten minutes, then the oven does the rest while you sort out the main. Leftovers reheat brilliantly the next day, which is always a bonus.

Ingredients for Easy Roasted Carrots with Thyme
- Fresh carrots – Large, firm carrots roast far better than small or limp ones, and their natural sugars caramelise beautifully in a hot oven.
- Olive oil – Coats every piece and helps them brown evenly. A good extra virgin olive oil adds a peppery note, but regular olive oil works perfectly well too.
- Fresh thyme – Brings an earthy, slightly woody flavour that pairs perfectly with sweet roots. Dried thyme works in a pinch, but fresh leaves are far better here.
- Onion salt – Adds a savoury, gently oniony backbone without making things taste sharp or raw. It's a small touch that makes a real difference. Can be substituted to simple salt + onion powder.
- Ground black pepper – Adds a bit of warmth and gentle heat that lifts the sweetness of the carrots. Freshly cracked pepper has more flavour than pre-ground.
How to Roast Carrots in the Oven
Step 1. Preheat your oven to 200°C (400°F). Wash and peel the carrots, then slice them on the diagonal into evenly thick pieces. Pop them into a large mixing bowl.
Step 2. Pick the leaves from the thyme sprigs and mince them finely. Add the thyme to the carrots along with onion salt, freshly ground pepper and olive oil. Toss everything together until each piece of carrot is fully coated.
Step 3. Spread the carrots out on a baking tray in a single layer. Cover the tray tightly with foil and roast for 20 minutes.
Step 4. Remove the foil, give the carrots a stir, and roast for another 15–20 minutes until they are tender with nice brown edges. Transfer to a serving dish and finish with a little extra ground pepper and a few fresh thyme sprigs on top.
How to Serve and Store Thyme Roasted Carrots
These thyme roasted carrots work as a side dish for almost any main meal. Serve them next to a Sunday roast, alongside grilled chicken, or with a piece of pan-fried fish for a quick weekday dinner. They also slot nicely into a vegetarian spread with roasted potatoes, a green salad and some crusty bread. For Christmas or Easter, add them to the table next to the main meat and they always go down well. They are equally good warm, at room temperature, or even cold the next day.
Leftovers keep in an airtight container in the fridge for up to four days. To reheat, pop them in the oven at 180°C for around 10 minutes to bring back the crisp edges, or use an air fryer at 180°C for 4–5 minutes. The microwave works too, though the texture will be softer. You can also chop cold leftovers into a grain bowl, fold them through pasta, or blend them into a quick carrot and thyme soup. They freeze well for up to two months — just thaw overnight in the fridge before reheating.

Top How to Serve and Store Thyme Roasted Carrots
- Cut the carrots evenly. This is the single biggest tip I can give you. When pieces are different sizes, the small ones burn while the big ones stay raw in the middle. Slicing on the diagonal gives you more surface area for those caramelised edges, and aiming for similar thickness across the board means everything cooks at the same pace. Take an extra minute with the knife and you will see a real difference in the final dish.
- Don't skip the foil step. Covering the tray for the first 20 minutes traps steam and softens the carrots from the inside out. Without it, the outside dries out before the middle has a chance to soften, and you end up with chewy bits. Once the foil comes off, the dry oven heat takes over and pulls moisture off the surface, which is where the colour and crisp edges come from. This two-stage method is what gives you tender insides and brown edges in the same bite.
- Use a properly hot oven. 200°C is the sweet spot for these oven roasted carrots. Anything cooler and you end up steaming the carrots rather than roasting them, which means no colour and no caramelisation. A hot oven concentrates the natural sugars and gives you that sweet, slightly nutty flavour that makes roast vegetables so good. If your oven runs cool, push the dial up to 210°C to compensate.
- Spread the carrots out properly. A single layer on the baking tray is non-negotiable. If the pieces are touching or piled on top of each other, they will steam in their own moisture instead of roasting. Use two trays if you need to, or scale the recipe down for a smaller batch. Crowded carrots come out pale and floppy, which is the opposite of what we want.
- Choose firm, fresh carrots. Old carrots that have lost their crunch will roast unevenly and taste a bit muted. Look for ones that feel heavy for their size, with smooth skin and bright orange colour. The greens, if still attached, should look perky rather than wilted. Garden carrots or farm shop ones tend to have the deepest flavour, but supermarket carrots work perfectly well for this recipe.
- Don't skimp on the olive oil. Two tablespoons for a kilo of carrots is the right amount. Less and they dry out; more and they go greasy. The oil helps the heat transfer evenly across each piece and carries the flavour of the thyme and onion salt right into the surface of the carrots. Extra virgin olive oil adds a peppery, fruity note that works really well with sweet root vegetables.
- Stir halfway through. When the foil comes off after 20 minutes, give the carrots a proper stir or flip them with a spatula. This brings the pieces from the bottom up to the top, where they get more colour, and stops anything from sticking. It also helps the seasonings redistribute around the tray. Skip this step and you will end up with one well-browned side and one pale side on each piece.
Roasted Carrots Recipe FAQ
How long do I roast carrots at 200°C?
Around 35–40 minutes total works for a kilo of carrots cut into evenly sized diagonal pieces. The first 20 minutes are covered with foil to soften them, then the foil comes off for another 15–20 minutes to brown the edges. Cooking time can vary slightly depending on the thickness of your slices and your oven, so always check the carrots are fork-tender before serving.
Can I use baby carrots instead?
Baby carrots work well, and you can roast them whole or halved lengthways. The cooking time stays roughly the same, though very small ones may need 5 minutes less in the oven. They tend to be sweeter than regular carrots, so you might want to add a pinch more pepper or a squeeze of lemon at the end to balance things out.
Why are my roasted carrots soggy?
Soggy carrots usually mean the tray was too crowded or the oven was not hot enough. When carrots are piled on top of each other, they steam rather than roast. Spread them out in a single layer with a bit of space between pieces, and make sure your oven has fully preheated to 200°C before the tray goes in.
Can I prepare this recipe in advance?
You can peel and slice the carrots up to a day ahead and keep them in a bowl of cold water in the fridge. Drain and pat them dry before tossing with oil and herbs. The whole roasted dish can also be made a few hours ahead and reheated at 180°C for 10 minutes just before serving.
Is this gluten free roasted carrots recipe suitable for coeliacs?
Yes, this dish is naturally gluten free. All the ingredients — carrots, olive oil, thyme, onion salt and pepper — are gluten free as standard. If you are cooking for someone with coeliac disease, double-check the label on your onion salt to make sure no anti-caking agents contain gluten.
