Inspired by my grandma’s recipe, this easy vegan caldo verde - green soup in Portuguese - is a deeply comforting and nourishing soup ready in 45 minutes, made from curly kale and waxy Yukon gold potatoes.
Heat oil in a large pot over medium heat. Add onion and cook, stirring occasionally, until onion soft and translucent, about 5-7 minutes. Turn heat down if onion browning, you don't want that.
Add garlic and potatoes and stir constantly, for one minute. Season well with salt and pepper.
Pour in water, add bouillon, salt and bay leaf and bring to a boil on high. Reduce heat to medium and cook until potatoes just fork tender, about 8-12 minutes.
Remove from heat, remove bay leaf and puree about one-third of the soup using an immersion blender. Return to heat, add kale and simmer for 5 minute, until kale is softened. Taste and adjust seasoning if desired.
Traditionally, caldo verde is served with a few pieces of fried sausage. To do this, slice a vegan sausage into ½ inch (1 cm) slices on the diagonal. Fry in a drizzle of oil until both sides are browned, about 2-3 minutes a side.
Soup will keep for up to 4 days in the fridge in an airtight container or up to a month in the freezer.
