Preheat the oven to 400 degrees. Place the sweet potatoes on a baking sheet and bake for 45 minutes to 1 hour until they are soft when pressed. Allow to cool until they can be comfortably handled; remove the skins and place them in a very large mixing bowl or stock pot.

While the potatoes are cooking, add the olive oil to a medium skillet and sauté the onions and garlic until translucent; 3-4 minutes. Remove from heat and add to the mixing bowl with the potatoes.

Add the cannellini beans, 6 cups chicken stock, and 1 ½ teaspoon adobo sauce to the mixing bowl or stock pot. Roughly mash the sweet potatoes with a potato masher or mixing spoon.

Process in batches either through a traditional blender or using an immersion blender until the mixture is completely smooth. Transfer batching into a large stock pot over medium heat.

Heat soup until lightly simmering. Taste and add salt or pepper. The soup will be thick. If desiring a thinner soup, add the remaining chicken stock, 1 cup at a time, fully whisking or stirring to incorporate before adding the second cup (if at all). If more spiciness is desired the remaining ½ teaspoon of adobo sauce may also be added. Serve hot garnished with a small amount of bacon crumblings.
