What You’ll Need

• 2 tablespoons extra virgin olive oil
• 1 large onion chopped
• 2 medium carrots chopped
• 1 rib celery chopped
• 3 cloves garlic pressed
• ½ teaspoon dried rosemary or 1 sprig fresh rosemary
• ½ teaspoon dried thyme or 4 sprigs fresh thyme
• 2 cans (15 ounces each) crushed tomatoes
• 1 large potato 10 ounces/300 grams, cut into bite-size pieces
• 4 cups vegetable broth or more for a thinner soup
• 3 cans (15 ounces each) cannellini beans drained, or 4½ cups cooked beans
• 1½ teaspoons salt
• ⅛ twists black pepper
• ¼ teaspoon red pepper flakes
• 7 ounces kale leaves chopped into bite-size pieces

How to Make the Soup

1. Warm 2 tablespoons olive oil in a large pot over medium heat.
2. Add chopped onion, chopped carrots, and chopped celery; season with a pinch of salt and sauté 5–10 minutes until softened and translucent.
3. Stir in pressed garlic, dried rosemary, dried thyme, and red pepper flakes; cook 1 minute until fragrant.
4. Add crushed tomatoes and the potato cut into bite-size pieces to the pot.
5. Pour in 3 cups vegetable broth and add 2 cans drained cannellini beans.
6. Blend 1 cup vegetable broth with 1 can cannellini beans until smooth, then stir the creamy mixture into the pot.
7. Season with 1½ teaspoons salt and a pinch of black pepper; bring to a boil, cover slightly ajar, then reduce heat and simmer 20 minutes.
8. While the soup simmers, rinse the kale, remove and discard the tough stems, and chop the leaves into bite-size pieces.

9. Add the chopped kale to the pot and cook 10–15 minutes more until the kale and potatoes are tender.

   

10. Taste and adjust salt as needed, then let the soup cool about 10 minutes before serving.

Expert Tips for Success

1. Let your aromatics cook longer for richer flavor: sauté the onion, carrot, and celery for up to 10 minutes until soft and starting to brown.
2. Be mindful of salt: canned beans and tomatoes can be salty—rinse your beans if you want less sodium, and add salt slowly, tasting as you go.
3. Properly prep your kale: discard tough stems and chop leaves into bite-size pieces so they soften evenly. Add kale towards the end of cooking, anywhere from 5 to 15 minutes depending on how tender you prefer it.
4. Get creaminess without dairy: blend a can of cannellini beans with 1 cup broth, then stir that back in to thicken the soup beautifully.
5. Use potato for body and creaminess: dice Yukon Gold or Russet potatoes into small pieces so they cook fully and add a velvety texture. For a heartier, protein-rich variation, see our Kale and White Bean Sausage Soup.
6. Adjust soup thickness to your liking: add more broth for a thinner soup, or simmer uncovered a bit longer if you want it thicker.
7. Finish with acid and oil: a splash of balsamic or squeeze of lemon brightens the flavors. Don’t forget a drizzle of high-quality olive oil and freshly cracked black pepper for that finishing touch.
8. Mix up toppings and sides: serve with toasted bread, a dollop of yogurt, shaved Parmesan, or stir in grains like farro, barley, or brown rice to bulk it up. For crunch, top with crispy kale chips.
9. Storage and reheating advice: cool completely before refrigerating or freezing. Reheat gently with a splash of water or broth. Try to avoid reheating multiple times for the best taste and texture.

Mix-Ins and Substitutions

EXTRA VIRGIN OLIVE OIL: You can swap in regular olive oil or any other vegetable oil you have.

ONION: Shallots or leek make great alternatives.

ROSEMARY & THYME: Use an Italian seasoning blend or add a couple of bay leaves if that’s what you have.

KALE: Swap kale with spinach, Swiss chard, savoy cabbage, bok choy, or Chinese cabbage.

DICED TOMATOES: Tomato puree, passata, or crushed tomatoes all work just fine.

CANNELLINI BEANS: Use canned or cooked dried cannellini beans. You can also try lima beans, butter beans, navy beans, or great northern beans instead.

VEGETABLE BROTH: Plain water works if needed, but boost salt and herbs to make up for the flavor difference. If you want a homemade base with clean, bright flavor, try this miso-ginger lemon detox broth.

POTATO: Optional, but definitely adds creaminess and depth. Yukon Gold and Russet potatoes are perfect for this.

Storing, Freezing, and Reheating

Make ahead: This kale soup is a meal prep dream because the flavors get better after resting overnight. Plus, it’s easy to refrigerate or freeze. For another make-ahead kale option, try our Kale Caesar Pasta Salad.

Freezer: Cool fully, store in a freezer-safe container, and freeze for up to 3 months.

Thaw: Defrost in the fridge over several hours or use your microwave’s thaw setting.

Reheat: Warm gently on the stove with a little water or broth, or microwave. Try to avoid reheating more than once for best texture.

Quick Answers to Common Questions

How long do you cook kale in soup?

It depends! For soft, buttery kale, cook for 15 to 30 minutes. If you want more bite and texture, 5 to 10 minutes will do just fine.

When should I add kale to my soup?

Generally, add kale towards the end of cooking—when the soup is mostly done and you’re happy with the taste (similar to the greens-last approach in Vietnamese pho with bone broth). It can cook quickly, in as little as 5 minutes, or take up to 20 minutes depending on your preference.

What are some substitutes for kale in soup recipes?

Try swapping kale for leafy greens like Swiss chard, green cabbage, bok choy, savoy cabbage, Chinese cabbage, spinach, or even broccoli for a different twist.
