This vegetarian and vegan recipe for cauliflower soup with potatoes is very low in fat and is a low-calorie vegetarian recipe. Unlike many other potato soup recipes, this one uses vegetable broth, vegan margarine and bay leaves to add flavor instead of butter. That means that this low-fat vegetarian soup recipe has just two grams of fat per serving. Because of that, you'll want to be sure to use a good-quality vegetable broth for the most flavor. If you're not using a fresh, homemade vegetable broth, you can use powdered broth or vegetarian bouillon cubes for a little extra to boost the flavor. 

This cauliflower and potato soup recipe is vegetarian, vegan, and as long as you use a gluten-free vegetable broth (read the label, as some are and some aren't gluten free), it's gluten free as well.

Use Caution When Blending Hot Ingredients

Steam expands quickly in a blender, and can cause ingredients to splatter everywhere or cause burns. To prevent this, fill the blender only one-third of the way up, vent the top, and cover with a folded kitchen towel while blending.
