Heat the olive oil in a large pot or Dutch oven over medium heat.
Add in the diced onion, carrots, and celery. Saute for 5-7 minutes or until the onions are translucent.
Add the minced garlic, lemon zest, and rosemary and cook for 1 more minute.
Add the white beans and vegetable broth. Give it a good stir and bring to a boil. Cover with a lid and reduce to a simmer. Simmer for 10 minutes, stirring occasionally. Remove from the heat.
Use an immersion blender to partially blend some of the soup for added creaminess while still keeping some texture.
Stir in the chopped kale and fresh lemon juice. Season to taste with kosher salt and freshly cracked black pepper. Add more lemon zest over each bowl before serving.
