One-Pot Tomato White Bean Soup

Posted on June 14, 2026

Delicious one-pot tomato white bean soup garnished with fresh herbs

Fasolatha, a traditional Greek white bean and tomato soup, brings warmth and nourishment to any weeknight dinner. The beans become tender and creamy, soaking up the tomato broth, which develops a satisfying depth of flavor. This dish is perfect for chilly evenings when you want something wholesome without spending hours in the kitchen.

Why This Tomato White Bean Soup Works

Preparing the beans in boiling water ensures they cook evenly and helps release their starches, thickening the soup naturally. Using fresh, ripe tomatoes is essential, as they provide a vibrant taste that canned versions often lack. When combined, the ingredients create a dish that is both hearty and satisfying, with a texture that clings deliciously to a spoon.

Ingredients

  • 500 grams / 17.6 dried Cannellini beans (or other small white beans)
  • 2 ½ liters (10 cups) boiling hot water (or half water and half vegetable stock)
  • 160 grams (1 large) onion (finely chopped)
  • 1 bay leaf
  • 2 carrots (sliced ½ cm (¼ inch thick))
  • 150 grams (1 + ½ cups) chopped celery (include some of the leaves as well)
  • 150 grams (medium-large) extra ripe tomato (hand grated, skin discarded)
  • 1 tablespoon tomato paste
  • 160 ml (⅔ cup) extra virgin olive oil (plus a bit extra to serve with)
  • Freshly ground pepper
  • OPTIONAL: hot red pepper flakes or 1 small chili pepper

This hearty soup brings comfort in each bowl, providing a delicious meal without the fuss.

How To Make It

  1. Prepare the beans: Rinse the dried beans under cold water, removing any debris. Soak them in a bowl of water overnight.
  2. Cook the beans: Drain the beans and place them in a large pot. Add the boiling water, bay leaf, and onion. Bring to a simmer over medium heat.
  3. Add vegetables: Once the beans are tender, stir in the carrots and celery. Cook for another 20 minutes until the vegetables are soft.
  4. Finish the soup: Add the grated tomato, tomato paste, olive oil, and pepper. Stir well and let it simmer for an additional 10 minutes.

The soup should have thickened slightly, coating the beans and vegetables with a rich, savory broth.

Quick Substitutions

  • Cannellini beans → Great Northern beans: Similar texture with a slightly firmer bite.
  • Fresh tomatoes → Canned diced tomatoes: This will alter the texture slightly, making the soup less chunky.
  • Olive oil → Avocado oil: Results in a milder flavor while maintaining the necessary fat content.
  • Celery leaves → Parsley: Provides a fresh, green note that complements the dish nicely.
  • Chili pepper → Black pepper: A less spicy alternative that still adds warmth.

Experimenting with these substitutions can give your Fasolatha a unique twist.

Tips Before You Start

Ensure you soak the beans overnight to avoid tough, undercooked results. If you’re short on time, opt for quick-soaking methods, boiling dried beans for an hour, and letting them sit for an hour covered. Another key is to use ripe tomatoes; they enhance the soup’s freshness and flavor. I once used less than ripe tomatoes, and the taste fell flat. The soup tastes better the next day after the flavors meld together, so consider making it ahead.

Common Mistakes to Avoid

  • Skipping the soak: Not soaking the beans leads to longer cooking times and tough texture. Always soak dried beans for optimal results.
  • Overcrowding the pot: If you add too many ingredients at once, cooking time will vary, risking undercooked beans. Cook in batches if necessary.
  • Using unripe tomatoes: They result in a bland soup. Always select the ripest tomatoes for the best flavor.

By avoiding these common pitfalls, your Fasolatha will have the depth of flavor it deserves.
