You know what I love about this time of year? Even here, it gets cooler. It’s been raining every single day, and as such it’s cooling the place down. As a result, it puts me in a constant mood for all things cozy and comforting. Case in point? This Whote Bean and Kale Soup. 
This soup screams comfort. It’s made with your typical mire poix, creamy white beans, comforting tomatoes, kale and amazing seasonings. It’s nourishing  while also being absolutely healthy. The best part? It’s made in your slow cooker!

I love slow cooker recipes, but you know what I love more? Not having to clean out the giant slow cooker container. While my slow cooker is brand new, if you have an older slow cooker (like I did) then you know the struggles of food sticking to your slow cooker. You know what it’s like to have to soak your slow cooker overnight. Hello Reynolds Kitchens Slow Cooker Liners! I honestly love these and if you’re a parent, I feel like you’ll love these even more.
All the enjoyment of the food without the mess. After it’s done, take out the liner and bam – No mess! I love that it’s also plastic free and BPA free – so it basically ticks all my boxes! The Slow Cooker Liners also come in two different sizes, so whether you have a 1-3 QT or a 3-8QT slow cooker, you can grab the right size for you. If you’re making a ton of slow cooker recipes this holiday season, be sure to grab a couple boxes of these Reynolds Kitchens Slow Cooker Liners. I even went through other women’s reviews on their Instagram page and people are lovinggggg these. 

How to Make White Bean and Kale Soup

The best thing about this soup is that you just put everything in your slow cooker, mix it together, and let it cook together. That’s it. Could it be simpler? 

What’s revealed is basically the perfect fall and winter soup. That being said, of course it works all year round too. I love that it’s chock full of veggies and flavour, while still being hearty.

You know what would also be amazing with this soup? Pesto. I…know. Ever since making batches of pesto, I’ve been adding it in everything. Pesto popcorn, pesto sandwiches, pasta, Buddha bowls. Everything you can think of. But a dollop of the creamy brine-y green goodness sauce would really add even more flavour to this soup. This soup is also so customisable, so feel free to switch it up how you want!
I hope you love this soup and that you are getting comforting weather your way, or that it’s coming soon! Either way, you’ll definitely devour this soup. Eat up and enjoy!

  • 1 large 188g red onion, diced
  • 4 stalks celery diced
  • 1 large carrot or two medium size carrots 226g, diced
  • 5 cloves 12g garlic, minced
  • 14 ounce can diced tomatoes
  • salt & pepper to taste I use 3/4 teaspoon sea salt and 1/4 teaspoon freshly ground black pepper
  • 1 tablespoon Italian seasoning or 1 teaspoon dried oregano 1 teaspoon dried parsley, 1 teaspoon dried basil
  • 2 15 ounces each cans white kidney beans
  • 4 cups vegetable broth
  • 2 cups kale
  • Juice of two limes about 1-2 tablespoons


  • Turn your slow cooker on and to warm. Line your slow cooker with one Reynolds Kitchens Slow Cooker Liner according to the box's directions.
  • Into the Reynolds Kitchens Slow Cooker Liner, add all of the ingredients into the slow cooker except the kale and the lime. Stir to combine.
  • Set the slow cooker to high for 3 hours or on low for 6 hours (for high, monitor the last 30 minutes and for low, monitor the last hour). At the end, stir in the kale and the lime juice and let it cook for about 5 more minutes.
  • Serve and enjoy!
In a soup like this, a high quality veggie broth makes all the difference. Adding an all natural veggie broth paste is great option to get high quality!

    Had this for lunch going into thanksgiving week. (So I wouldn’t feel too guilty about stuffing myself over the holiday!-haha) I was amazed at how satisfying something with no meat could be. Thanks for another great recipe!

    Easy and delicious! I added some lentils and my vegan meatballs into this soup, but without all that, this soup is FOR SURE a win in my book!

    • Gavin | Jessica in the Kitchen says:

      Awesome we’re so happy you enjoyed it CeCe! Thanks so much for reading!

  7. Bori says:

    Dear Jessica, could you please tell me if preparing the recipe is also possible without slowcooker? I don’t have one..
    I guess yes, but how long would you cook on a normal fireplace?
    Thank you very much and greetings from France 🙂

    • Gavin | Jessica in the Kitchen says:

      Hi Bori thanks so much for reading. It should work well if you sauté the veggies first then cook with the broth for around 30 minutes.
