This wonderfully savory kale soup with white beans and potatoes is fabulous healthy comfort food. It’s naturally vegan and gluten-free.
Why we love this recipe
I get super-jazzed about dinners like this one: deeply delicious, super-healthy comfort food. There’s so much good-for-you produce packed into this one-bowl meal, but it leads with comfort and satisfaction, so you’ll hardly notice its nutritional profile unless you want to.
Plus, it’s ready in 45 minutes, cooks in one pot, and makes a nice big batch that keeps well in the fridge for a week.
What you’ll need
Here’s a glance at the ingredients you’ll need to make this recipe.
The background notes
- The trinity of onion, carrot, and celery creates the first layer of flavor. Embrace a little bit of browning on the bottom of the pot and scrape it all up into the broth as you go. It adds a lot of depth.
- There’s no substitute for lots of fresh garlic. Give it an even chop, but don’t mince it too finely. That way it will contribute little pops of flavor and won’t burn.
- Tomato paste adds a backbone of umami and silkiness. You can use either the kind in the can or the double-concentrated kind in the tube — use the full measure either way.
- A touch of the English condiment Marmite adds an extra layer of savoriness to this soup. You won’t taste it per se, but it really does add nuance. You can use the same amount of the Australian Vegemite instead if you have that on hand. The two are different, but they serve a similar purpose in this recipe. Or leave it out if you prefer (or if you need this recipe to be gluten-free).
- Homemade stock works beautifully if you happen to have some on hand. If not, this recipe is great with a high-quality boxed veggie broth, too (that’s usually what I use). My favorite boxed vegetable broth by far is Imagine No Chicken lower-sodium broth. It has a great flavor profile and none of the rust-colored nonsense that plagues many other brands.
- Balsamic vinegar pairs beautifully with kale — its complex, earthy sweetness takes the edge off the kale’s bitterness without cloying. A midpriced option is perfectly fine — save the fancy balsamic for drizzling.
- A little bit of chopped fresh flat-leaf (Italian) parsley stirred in after cooking adds freshness. It’s not strictly necessary, but I like the dimension it adds.
The stars of the show
- I like to use Yukon Gold potatoes for their excellent ratio of creaminess to starchiness, but feel free to substitute a starchy variety like Russets or Idahos if that’s what you’ve got.
- This soup works equally well with curly or lacinato kale (also called dinosaur or Tuscan kale or cavolo nero). Depending on the specific variety and the season, you’ll need to do a little more or less simmering of curly kale to make it nice and tender. Most lacinato kale needs just a few minutes.
- You can use any canned white beans in this recipe. I tend to use cannellini beans, which are are also called white kidney beans. They’re mild, creamy, and fairly large. The two cans called for in this recipe equal about 3 ½ cups of cooked beans, from one heaping cup dried. You can of course use beans cooked from scratch if you prefer.
How to make it
Here’s what you’ll do to make this recipe in one pot in about 45 minutes. You can watch all the steps in action in the video that accompanies this post.
- You’ll start with a nice big pot that has a lid (which you’ll use later). I use a 7.25-quart Dutch oven. Heat the olive oil, then add the onion, carrots, and celery, along with some salt, and cook until a little bit browned and softened. Stir in the garlic, tomato paste, and marmite if you’re using it, and cook for a couple more minutes.
- Pour in the broth and bring to a boil, then add the potatoes, cover, and cook until they’re just tender.
- Add the beans and the kale (by the handful, stirring to incorporate until it all fits) and cook until the kale is tender.
- Off the heat, stir in the balsamic vinegar, the parsley, and some freshly ground black pepper. Serve with grated cheese if you like (or skip it — it’s great either way). That’s it!
Expert tips and FAQs
To make this recipe vegan, simply don’t include grated cheese, or use a vegan version. To make it gluten-free, omit the Marmite.
You sure can. Like many soups, it only improves in flavor as it has a chance to settle into itself. Store it in an airtight container in the fridge for up to a week. It will freeze just fine too, for up to a year. As always, the textures will soften a bit after freezing.

Love this recipe, but I’m interested to know what the serving size that has 379 calories in it would be. I’m tracking calories, so it would be helpful. Would 1 serving be 1 cup? Or more?
Thanks so much
Hi Cari, the nutrition info was calculated to get six servings from the recipe. I’m not exactly sure how many cups are in each portion. You could weigh the whole batch (or measure it volumetrically) and divide by six if it’s important to you. Sorry I can’t give you an exact answer right now!
