Ingredients

Scale
  • 2 tablespoons olive oil
  • 1 medium yellow onion, finely chopped
  • 34 garlic cloves, minced
  • 2 medium carrots, diced
  • 2 medium celery stalks, diced
  • 2 (15-ounce) cans cannellini beans, rinsed and drained
  • 4 cups (960 ml) vegetable broth, low-sodium if possible
  • about 4 cups fresh kale, chopped, stems removed
  • 1 teaspoon dried thyme
  • 1 bay leaf
  • 2 tablespoons fresh lemon juice
  • Salt and freshly ground black pepper, to taste
  • Optional: red pepper flakes, Parmesan cheese for garnish

Instructions

  1. In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the chopped onion, diced carrots, and celery. Cook for about 7-8 minutes, stirring occasionally, until the vegetables soften and the onion turns translucent.
  2. Add the minced garlic and cook for another 1-2 minutes until fragrant.
  3. Transfer the sautéed vegetables to the slow cooker. Add the rinsed and drained cannellini beans.
  4. Pour in 4 cups (960 ml) of vegetable broth. Stir in dried thyme and bay leaf. Season lightly with salt and pepper.
  5. Cover and cook on low for 6-8 hours or on high for 3-4 hours.
  6. About 30 minutes before the cooking time ends, add the chopped kale to the slow cooker and stir well.
  7. Once cooked and kale is tender, remove the bay leaf. Use an immersion blender to puree about one-third of the soup directly in the pot to create a creamy texture. Alternatively, carefully blend a portion in a regular blender and return it to the pot.
  8. Stir in 2 tablespoons of fresh lemon juice. Adjust seasoning with salt, pepper, and optional red pepper flakes.
  9. Serve warm, optionally garnished with Parmesan cheese or a drizzle of olive oil.

Notes

Sautéing the vegetables before slow cooking enhances flavor. Add kale late to avoid bitterness and mushiness. Puree a portion of the soup for creaminess without dairy. Adjust salt gradually as slow cooking concentrates flavors. If soup is too thick after blending, add broth or water to reach desired consistency.
