Ingredients
Method
- Heat 1 tbsp olive oil in a large pot over medium heat. Add onion, carrots, and celery; cook until softened, 6 to 8 minutes. Add garlic and red pepper flakes; cook 1 minute.
- Pour in broth and beans. Bring to a boil, then reduce heat and simmer for 10 minutes.
- Stir in kale; cook until wilted and bright green, 3 to 4 minutes. Season with salt, pepper, and lemon juice.
- Ladle into bowls and top with grated Parmesan, a drizzle of olive oil, and black pepper. Serve hot.
Notes
If you have a Parmesan rind, simmer it with the broth in Step 2 and discard before serving. The soup keeps well in the fridge for up to 4 days and can be frozen for up to 3 months.
