What You Can Do Better
This soup is already full of wholesome ingredients, but a few small choices can make it even better.
- Use two types of beans: Cannellini beans, butter beans, or cranberry beans work well. They add a creamy texture while keeping the soup filling.
- Choose green or brown lentils: These varieties hold their shape better than red lentils, which tend to soften and break down during cooking.
- Build flavor slowly: Give the onions, leeks, and celery enough time to soften and develop a little golden color. This creates a deeper flavor without needing complicated seasonings.
- Don’t skip the mushrooms: Dried porcini mushroom powder gives the broth a savory, earthy taste. If you cannot find it, use finely chopped dried mushrooms or a little mushroom stock.
- Add kale near the end: Kale needs only a short cooking time. Adding it too early can make it overly soft and dull in color.
- Finish with something fresh: A spoonful of pesto, fresh lemon juice, or a little olive oil can brighten the finished soup.

How to Make Bean and Lentil Soup with Kale
Step 1: Prepare the Beans and Lentils
If using dried beans, soak them overnight in plenty of water. Drain and rinse them before cooking. Place the beans in a large saucepan, cover with fresh water, and simmer until tender. This usually takes around 45–75 minutes, depending on the variety and age of the beans. Reserve about 2 cups of the cooking liquid before draining.
In a separate saucepan, rinse the lentils and cook them in water until tender but still holding their shape, usually around 20–30 minutes. Drain any excess water and set the lentils aside.
If you are short on time, canned beans can be used instead. Drain and rinse them before adding to the soup.
Step 2: Cook the Aromatic Vegetables
Heat the olive oil in a large soup pot or Dutch oven over medium heat. Add the chopped onions, leeks, celery, and a little salt. Cook for approximately 10–12 minutes, stirring occasionally, until the vegetables soften and the onions begin to turn lightly golden.
Add the sliced garlic and cook for another minute. Stir in the porcini mushroom powder and black pepper. Let everything cook briefly so the garlic and mushrooms release their aroma.
Step 3: Add the Tomatoes and Broth
Add the canned whole tomatoes to the pot, breaking them into smaller pieces with a wooden spoon. Stir in the cooked beans, lentils, and vegetable broth or reserved bean cooking liquid.
Add the red chili flakes and mix everything well. Bring the soup to a gentle boil, then reduce the heat and allow it to simmer for about 15 minutes. This gives the beans, lentils, and vegetables time to absorb the tomato and mushroom flavors.
Step 4: Add the Kale
Wash the kale thoroughly and remove the tough stems. Chop the leaves into bite-sized pieces.
Stir the chopped kale into the simmering soup. Cook for another 5–7 minutes, or until the leaves soften but still retain some texture.
Taste the broth and adjust the salt, pepper, and chili flakes as needed. If the soup becomes too thick, add a little more vegetable broth or water until it reaches your preferred consistency.
Step 5: Serve and Enjoy
Turn off the heat and let the soup rest for a couple of minutes. Ladle it into serving bowls and finish with pesto, toasted pumpkin seeds, or a drizzle of olive oil.
For a little extra freshness, squeeze some lemon juice over the top just before serving. Enjoy it warm with toasted sourdough, garlic bread, or a simple green salad.

Tips for Making the Best Bean and Lentil Soup
- Soak dried beans properly: Overnight soaking helps reduce cooking time and allows the beans to cook more evenly.
- Avoid overcooking lentils: Green and brown lentils are ideal because they stay relatively firm. Check them regularly while cooking.
- Use good-quality tomatoes: Whole peeled canned tomatoes provide a rich base. Crush them by hand or with a spoon before adding them to the pot.
- Adjust the consistency: Add more broth for a thinner soup or simmer uncovered for a few extra minutes if you prefer a thicker consistency.
- Don’t overcook the kale: Add it toward the end to preserve its color and texture.
- Make it ahead: The flavors develop further after resting, making this soup a good option for meal preparation.

Storage and Reheating
Refrigerator: Allow the soup to cool completely before transferring it to an airtight container. Refrigerate for up to 4 days.
Freezer: This soup freezes well. Divide it into individual portions and store in freezer-safe containers for up to 3 months. Leave a little space at the top of each container because the liquid expands as it freezes.
Reheating: Thaw frozen soup overnight in the refrigerator if possible. Reheat it in a saucepan over medium-low heat, stirring occasionally. Add a splash of water or vegetable broth if it has thickened during storage. Make sure it is heated thoroughly before serving.

Frequently Asked Questions
Can I use canned beans instead of dried beans?
Yes. Canned cannellini, navy, or butter beans are convenient alternatives. Use approximately two 15-ounce cans, drained and rinsed. Add them directly to the soup instead of cooking dried beans separately.
Which lentils are best for this soup?
French green lentils are a great choice because they hold their shape during cooking. Brown lentils are another good option. Red lentils are less suitable because they break down quickly and make the soup thicker.
Can I make this soup without mushroom powder?
Yes. You can use finely chopped dried mushrooms, mushroom stock, or simply replace the mushroom powder with a little extra vegetable broth. The flavor will be slightly different but still delicious.
Is Bean and Lentil Soup with Kale vegan?
Yes, the basic recipe is naturally vegan and dairy-free when prepared with olive oil and vegetable broth. Avoid dairy-based toppings such as feta or goat cheese if you want to keep it completely plant-based.
Can I use spinach instead of kale?
Yes. Spinach works well as a substitute, but it cooks much faster. Stir it into the soup during the final 1–2 minutes of cooking.
Why is my bean and lentil soup too thick?
Beans and lentils absorb liquid as they cook and continue to thicken the soup during storage. Simply add a little warm vegetable broth or water while reheating until you reach the desired consistency.
Can I prepare this soup in advance?
Absolutely. You can prepare it a day ahead and refrigerate it in an airtight container. The ingredients have more time to blend together, making the broth even more flavorful when reheated.
What beans work best in this recipe?
Cannellini beans, cranberry beans, navy beans, and butter beans are all good choices. Choose beans that hold their shape during simmering rather than becoming too soft.
