Set your oven to 425°F (220°C) and let it heat up.

Chop the shallots into small pieces and cut the sweet potatoes into cubes, about an inch in size.

On a baking sheet, arrange the sweet potato cubes and shallots. Pour olive oil over them, sprinkle thyme and cumin, then mix everything so it's evenly coated.
04 -
Bake for roughly 30 minutes, or until the sweet potatoes are soft and slightly caramelized.

Take the tray out of the oven and allow it to cool a bit. Put the cooked shallots and sweet potatoes into a blender or food processor.

Pour in 4 cups of broth, and add your desired amount of salt and pepper.
07 -
Blend until you get a creamy texture. If your blender isn't large enough, try blending it in portions.

Too thick? Add more broth. Too thin? Simmer on low heat to reduce it a little. Don't forget to taste and adjust flavors.
09 -
Ladle into bowls while it's hot and dollop with sour cream if you’re using it.

Top it off with freshly chopped herbs or chives if desired.
