Method
Preparation
- If using dried beans, rinse and soak 2 cups of dried white beans overnight in plenty of water. Drain, then simmer in fresh water for about 1 hour until tender but not mushy. If using canned beans, skip this step.
- Heat 3 tablespoons of olive oil in a large skillet over medium heat. Add diced onion and cook for 3-4 minutes until soft and translucent. Add minced garlic and red pepper flakes, cooking for another minute, stirring constantly to avoid burning.
- Transfer the sautéed onion and garlic to the slow cooker. Add cooked beans, 6 cups of vegetable broth, 1 can of crushed tomatoes, dried rosemary, thyme, salt, and pepper. Stir gently.
Cooking
- Set the slow cooker to low and cook for 6 to 8 hours.
- About 30 minutes before serving, add chopped kale to the soup. Stir, cover, and let it wilt and soften while still retaining a slight bite.
- Taste and adjust salt, pepper, or red pepper flakes as needed. If the soup is too thick, add a splash of broth or water.
Notes
For best flavor, let the soup cook a full 8 hours on low. Adjust the amount of red pepper flakes to control heat levels. Store leftovers in an airtight container in the fridge for up to 5 days. This soup freezes well; just reheat when ready to serve.
