Looking for a healthy vegan kale soup? Try this Tuscan Kale Soup Recipe made with roasted tomatoes, orzo, kale in a spicy broth. A must make with less than 250 calories a serving. 

So, I’m pretty sure that soup is always the answer.

This time of year, I want soup for 64% of my meals. I crave it on chilly, snowy nights and the leftovers always make the perfect lunch. Therefore, this Tuscan kale soup is a medley of some of my favorite winter foods: tender orzo pasta, fire-roasted tomatoes, and kale in a spicy broth.

My husband always tells me that my soups are one of his favorite things I make. Which, sometimes feels like an odd compliment. Isn’t soup one of the easiest foods to cook? I find that no matter what’s lurking in my fridge or pantry, I can almost always make a killer soup. 

Overall, a hit with both my family and hundreds of readers, this Tuscan Kale Soup is no exception and guaranteed to be a winner in your house as well. 

Ingredients for Tuscan Kale Soup

It should come as no surprise that you’ll need kale for this soup. Generally, I prefer a Tuscan or Latino kale, the one with the flatter, darker leaves, but curly kale will also work. 

In addition, you will need:

  • Aromatics, like garlic, onion, celery and carrots
  • Seasonings, like oregano and basil and crushed red pepper flakes
  • Canned fire-roasted tomatoes; these give this soup so much flavor, but regular canned diced tomatoes work too 
  • Good quality vegetable broth
  • Orzo pasta, regular or whole wheat
  • Fresh lemon juice

Healthy Kale Soup Tips + Instructions

When you’re ready to make the soup, sauté the vegetables in fat first. This is where most of the flavor comes from, especially since we aren’t using any animal products. First, add a thin layer of olive oil or vegetable oil on the bottom of the stock pot and let it get hot before adding in the onions, celery and carrots. 

From there, cook over medium-low heat until caramelized and browned. This may take 20 minutes, just make sure to stir often so it doesn’t burn. 

Next, add in a can of fire roasted tomatoes. You should be able to find these in the same aisle as regular canned tomatoes. Fire-roasted tomatoes give more depth and flavor to this soup than regular tomatoes, but you can use regular if that’s all you can find. For low sodium diets, make sure to select no-salt added tomatoes. 

Then, here is where you will also add the broth, water, and orzo pasta. The secret to really good soup is of course, good broth. I often make my own from whatever scraps I have lying around, especially in the age of the Instant Pot

However, there are some great store-bought options that I rely on often: Pacific Foods, Better than Bouillon Vegetable Base and Orrington Farms Broth Base.

Once the pasta is tender, add in the fresh kale until just wilted. Stir in lemon juice right before serving. The added acid balances the heat and the salt; it’s my secret weapon in almost every meal.

Ladle into bowls, then top with freshly ground black pepper if desired before serving. For an added umami boost, I like to sprinkle on either regular or dairy-free parmesan cheese. Violife makes a great parmesan cheese, or consider my homemade parmesan recipe.

Can I add in white beans? 

For a heartier soup, consider adding in cooked white beans when you add the orzo pasta. White beans contain 8g of protein and 6g of fiber per half cup, making this a healthy variation. 

While most creamy beans would work well in this soup, I’d recommend a small white bean, like a cannellini bean or great northern bean. 

If you do add in white beans, you can also blend some of the beans with the broth and vegetables in a blender before adding the pasta. This gives more heartiness and body to the kale soup without having to add any dairy. 

Is Kale good for you in soup?

Honestly, kale is a nutrient powerhouse– there’s a reason its popularity has skyrocketed over the past decade. It’s delicious both cold, like in salads, and warm as in this Tuscan Kale Soup. Unlike more delicate greens, kale holds its shape after cooking and is perfect in soup.

Kale is packed with vitamins A, K, C and also contains calcium, potassium, and copper. Like other members of the cruciferous vegetable family, kale consumption is linked to reducing cancer risk, likely due to containing glucosinolates, which have been shown to have anti-carcinogenic properties.

This Tuscan Kale Soup is similar to Olive Garden’s famous zuppa toscana soup, but much healthier! It’s packed with vegetables, it cholesterol free and tastes just as rich and decadent without all of the bacon and heavy cream in their version.

How do I use Kale?

Even if you don’t think you like kale, I urge you to try this soup. Finely chopping the kale first helps to create a less bitter bite– even my father-in-law who swears he hates kale loves this soup.

Remove the stems, then stack the kale leaves on top of one another. Tightly roll, then thinly slice from the short end creating thin kale ribbons. From here, you can stack and cut in half widthwise or leave as is.

Can you freeze kale soup?

To freeze soup, place in freezer-safe containers or bags. If using a bag, remove as much of the air as possible; I usually like to lay the bags flat for easier storage. Let cool completely, then place in the freezer for 2-3 months.

To reheat, warm on the stovetop or in the microwave. As the orzo pasta will absorb more broth as it cools, you may need to add in the additional broth while reheating.

Can I use spinach instead of kale in soup?

Yes, you can use either baby or regular spinach leaves in this Tuscan kale soup. If using mature spinach leaves, then I recommend removing any tough stems and roughly chopping them before adding to the soup.

      Excellent. Easy read easy cook. I used chard, spinach, kale along with the mentioned veggies. Added potatoes as well. Substitute barley for orzo, and didn’t use lemon. Tastes delicious! Used Halo vegan chicken soup, and was delicious! Took 1 hr bc potatoes to cook, but it is ok. Will try the pasta fagiole soup next!
