Vegan Butternut Squash Soup

Heat olive oil in a large saucepan over medium heat. Add onions, garlic, and ginger. Cook and stir until browned, about 5 minutes. Stir in 1/2 teaspoon salt, allspice, nutmeg, cinnamon, cumin, cloves, coriander, paprika, and chile flakes. Add butternut squash, yam, carrots, and celery. Add enough water to just cover.

Increase heat and bring soup to a boil. Reduce heat and simmer until all vegetables are fork-tender, 30 to 45 minutes.

Fill a blender halfway with soup. Cover and hold lid down with a potholder; pulse a few times before leaving on to blend. Pour back into the saucepan. Repeat with remaining soup. Add maple syrup, apple cider vinegar, and remaining 1 teaspoon salt.
