Ingredients
  

  • Olive oil: For sautéing and adding richness.
  • Yellow onion: The flavor foundation of the soup.
  • Carrots and celery: Classic aromatics for depth and sweetness.
  • Garlic: Adds warmth and savory complexity.
  • Tomato paste: A spoonful for umami and color.
  • Smoked paprika or regular paprika: A subtle smokiness that makes the broth cozy.
  • Dried thyme and dried oregano: Earthy, herbal notes.
  • Red pepper flakes (optional): A gentle kick.
  • Low-sodium vegetable or chicken broth: The base of the soup.
  • Water: To adjust consistency without overpowering the flavors.
  • Bay leaf: Adds roundness to the broth.
  • Cannellini or great northern beans: Two 15-ounce cans, drained and rinsed. Cannellini are creamy; either works.
  • Kale: Curly or lacinato (dinosaur) kale, stems removed and leaves chopped.
  • Lemon: Zest and juice to brighten the soup at the end.
  • Fresh parsley: For freshness and color.
  • Salt and black pepper: Season generously to taste.
  • Parmesan rind (optional): Adds a savory, cheesy depth if you’re not keeping it vegan.

Method
 

  1. Warm the pot: Set a large soup pot or Dutch oven over medium heat. Add 2 tablespoons olive oil and let it shimmer.
  2. Sauté aromatics: Add 1 diced onion, 2 diced carrots, and 2 diced ribs of celery. Cook 6–8 minutes, stirring, until soft and lightly golden. Season with a pinch of salt.
  3. Add garlic and tomato paste: Stir in 4 minced garlic cloves and 1 tablespoon tomato paste. Cook 1–2 minutes until fragrant and the paste darkens slightly.
  4. Spice it up: Sprinkle in 1 teaspoon dried thyme, 1 teaspoon dried oregano, 1 teaspoon smoked paprika, and a pinch of red pepper flakes if using. Toast for 30 seconds to bloom the spices.
  5. Deglaze and add liquids: Pour in 6 cups low-sodium broth and 1 cup water. Scrape any browned bits from the bottom. Add 1 bay leaf and the optional Parmesan rind.
  6. Add beans: Stir in two cans of drained, rinsed white beans. Bring to a gentle boil, then reduce to a simmer.
  7. Simmer for flavor: Let the soup simmer uncovered for 15–20 minutes so the flavors meld and the broth gains body.
  8. Blend a little (optional but recommended): For a creamier, protein-rich texture, use an immersion blender to briefly puree 1–2 cups of the soup right in the pot, or ladle into a blender and return. Keep plenty of beans whole for texture.
  9. Add kale: Stir in 5–6 packed cups chopped kale. Simmer 5–7 minutes until tender but still bright.
  10. Finish with brightness: Turn off the heat. Stir in the zest of 1 lemon and 1–2 tablespoons lemon juice. Add 2–3 tablespoons chopped parsley. Taste, then season with salt and black pepper as needed.
  11. Serve: Ladle into bowls and drizzle with a bit of olive oil. Top with shaved Parmesan or nutritional yeast if you like. Crusty bread on the side is never a bad idea.
