Dice onions and drain the white cannellini beans. Set aside
Switch instant pot to sauté mode and add olive oil
After 2 minutes, add diced onions and salt. Sauté until translucent. This will take about 5-7 mins.
Now add paprika, cayenne pepper and black pepper. Sauté for another minute.
Add canned tomatoes and vegetable broth.
Switch instant pot to soup mode. Close lid and set to high for 10 minutes. If using a normal pot, close lid and keep on low-medium heat for 15 mins.
Quick release the instant pot. If using a normal pot, switch off stove.
Add drained white cannellini beans, sugar and basil leaves.
Blend with immersion blender.
Your soup is ready! You can add salt and pepper to taste. You can also add cream if you'd like, though I use the cream more as a garnish.
