- yellow onion 1 medium
- garlic 2 cloves
- coriander ½ tsp
- cumin ¼ tsp
- vegetable broth 4 cup

- black pepper
🍳 Cookware
- baking sheet
- Dutch oven or soup pot
- wooden spoon or sturdy silicone spatula
- blender
-
1Preheat the oven to 400°F. Line a large rimmed baking sheet with parchment paper for easy cleanup, if desired.
-
2To prepare your carrots , peel them and then cut them on the diagonal so each piece is about ½″ thick at the widest part (see photos).
-
3Place the carrots on the baking sheet . Add 2 tablespoons olive oil and ½ teaspoon of the salt . Toss until the carrots are lightly coated in oil and seasonings. Arrange them in a single layer.
-
4Roast the carrots until they’re caramelized on the edges and easily pierced through by a fork, 25 to 40 minutes , tossing halfway. (Heirloom carrot varieties will roast in as little as 25 minutes, but regular carrots are more dense and typically require 35 to 40 minutes.)
-
5Once the carrots are almost done roasting, in a Dutch oven or soup pot , warm the remaining 1 tablespoon olive oil over medium heat until shimmering. Add the yellow onion and ¼ teaspoon salt. Cook, stirring occasionally, until the onion is softened and turning translucent, 5 to 7 minutes .
-
6Add the garlic , coriander and cumin (if following a variation, see recipe notes for additions). Cook until fragrant while stirring constantly, about 30 seconds to 1 minute . Pour in the vegetable broth and water , while scraping up any browned bits on the bottom with a wooden spoon or sturdy silicone spatula .
-
7Add the roasted carrots to the pot when they are out of the oven. Bring the mixture to a boil over high heat, then reduce the heat as necessary to maintain a gentle simmer. Cook for 15 minutes , to give the flavors time to meld.
-
8Once the soup is done cooking, remove the pot from the heat and let it cool for a few minutes. Then, carefully transfer the hot soup to a blender , working in batches if necessary. (Do not fill past the maximum fill line or the soup could overflow!)
-
9Add the butter , lemon juice (or lime, if following the Thai variation), and several twists of black pepper . Blend until completely smooth. Add additional salt and pepper if necessary, to taste. Add another tablespoon of butter if you’d like more richness, or a little more lemon juice if it needs more zing. Blend again, and serve.
