When you roast whole carrots, something magical happens — their natural sugars caramelize, the edges turn golden, and the flavor deepens into a sweet, earthy perfection. This roasted rainbow carrot recipe brings that transformation to life, pairing vibrant root vegetables with a creamy toasted sunflower dressing and a bright sprinkle of sumac and fresh mint.
This colorful side dish is more than just eye candy; it’s wholesome, naturally gluten-free, and can easily be made vegan. The contrast of roasted sweetness, nutty richness, and citrusy tang makes it a stunning yet simple dish for any dinner table.
The Magic of Whole Roasted Carrots
Many chefs love the technique of roasting vegetables whole, especially root veggies like carrots, beets, or parsnips. Leaving the skins on helps lock in moisture and flavor while giving the outside a subtle crispness. By roasting the carrots directly on coarse salt and brushing them lightly with oil, the natural sweetness intensifies without the need for added sugar.
The result? Carrots that are beautifully caramelized on the outside and perfectly tender within — a side dish that feels both rustic and refined.
Should You Peel Rainbow Carrots?
In classic cooking schools, peeling vegetables was almost a rule. The reasoning was that skins can sometimes add bitterness, especially in stocks or sauces that are reduced. But in this recipe, we’re skipping the peeler — and for good reason.
Carrot skins are loaded with fiber, antioxidants, and nutrients that contribute to both flavor and health benefits. Plus, unpeeled rainbow carrots look absolutely gorgeous with their natural hues of purple, yellow, and orange.
Any slight bitterness from the skin is perfectly balanced by the caramelization that happens in the oven, along with the creamy, sweet-salty sunflower dressing. So go ahead — leave those peels on and embrace the beauty of imperfection.
Why Roasting Wins Over Boiling
If you’ve ever boiled vegetables and watched the color fade or the texture go limp, you know how easy it is to lose both nutrients and taste that way. Roasting, on the other hand, concentrates flavor rather than diluting it.
Many vitamins and minerals are water-soluble — meaning they leach out into the cooking water when you boil your veggies. When roasting, everything stays inside the vegetable, giving you more nutrition and richer flavor in every bite.
So the next time you’re craving a healthy vegetable side dish, roasted rainbow carrots are the way to go.
The Story Behind the Orange Carrot
Carrots weren’t always orange! Originally cultivated in Central Asia, early varieties were often purple, yellow, or white. It wasn’t until the 16th century that orange carrots became popular across Europe — not because of national symbolism, but because the orange types were sweeter and more stable to grow.
Today, rainbow carrots celebrate that heritage with a spectrum of colors that each offer unique nutritional perks and antioxidants.
Toasted Sunflower Dressing: A Creamy, Nut-Free Alternative
Now, let’s talk about the star of the show — the toasted sunflower seed dressing. It’s thick, creamy, slightly nutty, and completely dairy-free. Toasting the sunflower seeds deepens their flavor, and when blended with a touch of honey, vinegar, and oil, you get a luscious dressing that feels indulgent yet wholesome.
This dressing also happens to be vegan-friendly if you swap the honey for maple syrup or agave. It’s a perfect match for roasted carrots but also great drizzled over grain bowls, roasted potatoes, or grilled veggies.
Why Sunflower Seeds Are a Superfood
Sunflower seeds pack a nutritional punch. They’re rich in vitamin E, selenium, and healthy fats that support heart health and reduce inflammation. They also add a beautiful crunch and a subtle sweetness that complements the roasted carrots perfectly.
So even though this dish looks fancy, it’s made with simple, affordable ingredients that happen to be really good for you.
Fresh Mint and Sumac for the Perfect Finish
To bring everything together, we’ll top the carrots with fresh mint leaves and a sprinkle of sumac. Mint adds a refreshing herbal lift, while sumac — a Middle Eastern spice with a lemony tang — gives a burst of brightness that cuts through the richness of the sunflower dressing.
This final touch elevates the dish, turning humble roasted vegetables into something that feels restaurant-worthy.

- Total Time: 50 min
Description
A beautifully simple side dish that’s naturally gluten-free, easily vegan, and bursting with flavor. Whole roasted rainbow carrots are caramelized to perfection and topped with a creamy, nut-free toasted sunflower seed dressing, fresh mint, and a dusting of sumac.
Ingredients
For the Roasted Carrots
10 medium rainbow carrots, similar in size
1 tbsp vegetable oil (high smoke point, such as sunflower or canola oil)
½ tsp sea salt
½ bunch fresh mint, leaves picked
¼ tsp ground sumac, for garnish
For the Sunflower Butter
30 g raw sunflower seeds (plus extra for garnish)
1 tbsp vegetable oil
For the Sunflower Dressing
3 tbsp vegetable oil
2 tbsp white wine vinegar (or rice vinegar)
¼ tsp salt
1 tsp honey (or agave/maple syrup for vegan version)
1 tbsp water
A pinch (1/16 tsp) xanthan gum (optional, for extra creaminess)
Instructions
-
Preheat the Oven
Set your oven to 200°C (400°F) and line a baking tray with parchment paper. -
Prepare the Carrots
Wash the carrots thoroughly, scrubbing off any dirt with a cloth or scouring pad. Trim the tops but leave a bit of the stem for presentation. -
Roast the Carrots
Brush the carrots lightly with vegetable oil and season generously with salt. Arrange them in a single layer on the tray and roast for 35–45 minutes, or until tender and caramelized around the edges. -
Toast the Sunflower Seeds
Spread 30 g sunflower seeds on a small baking sheet and toast in the oven for 5–6 minutes, until fragrant and golden. Set aside a spoonful for garnish. -
Make the Sunflower Butter
While the seeds are still warm, transfer them to a food processor with 1 tbsp oil. Blend until a smooth paste forms, scraping down the sides as needed. -
Blend the Dressing
Add the rest of the dressing ingredients (oil, vinegar, salt, honey, water, and xanthan gum if using) to the sunflower butter. Blend until completely smooth and creamy. -
Assemble the Dish
Slice larger carrots in half for easier serving. Arrange the roasted carrots on a platter, drizzle with sunflower dressing, and sprinkle with sumac and toasted sunflower seeds. Finish with a handful of fresh mint leaves. -
Serve and Enjoy!
Serve warm or at room temperature — perfect as a colorful holiday side or a light vegetarian main.
Notes
- No food processor? Use store-bought sunflower butter, then whisk the dressing by hand.
- Vegan swap: Replace honey with maple syrup or agave.
- Storage: Keep leftover dressing in a sealed jar in the fridge for up to 5 days.
- Texture tip: Always blend seeds while they’re still warm — this helps release their natural oils for a smoother butter.
- Serving idea: Pair with roasted cauliflower, quinoa salad, or grilled tofu for a full meal.
