Make the creamiest Cauliflower White Bean Soup with a few simple ingredients like cannellini beans and tahini. Flavored with thyme and sage, this earthy soup is hearty and delicious!
Heat a large pot over medium heat. Add the onion and celery. Cook for 5-7 minutes, until the veggies start to soften. Use a splash of vegetable broth if they veggies start to stick.
Add the garlic, thyme, sage, salt, and pepper. Cook until fragrant, about 1 minute.
Stir in cauliflower, beans, broth, tahini, and lemon juice. Bring to a boil. Reduce heat to maintain a simmer, cover and cook until the cauliflower is very tender, 15 to 20 minutes.
Use an immersion blender or transfer to a regular blender to puree until smooth.
