Winter is perfect soup weather. Although soup is one of my comfort foods and I eat it all year long, pairing this slow cooker vegetarian bean soup with cold weather makes perfect sense.

I remember as a kid coming inside from playing in the colder weather, and my mom would lunch waiting. It was usually something like a steaming mug of tomato soup, a grilled cheese sandwich, and it was sooo good.

Soups are, for the most part, easy to make. Just chop your ingredients to a uniform size, and you are half-way to an amazing meal. Soups are flexible, too. You can vary the ingredients and tailor them to what you like or what you have on hand. Exchange beef for chicken, sausage for ham or kidney beans for white beans. It is really up to you.

Another great reason to make soup is that it stores in the freezer and refrigerator very well. One of my favorite ways to store it is in pint deli containers. These containers are refrigerator and freezer safe for storage, and can go into the microwave to heat your bowl of liquidy goodness. Just remember that you will need to remove the lid prior to reheating.

What is your favorite way to serve soup?

Hands down, my favorite way to serve soup is with fresh baked crusty bread slathered with butter. I like to dip the bread into the soup while I am eating it, or with some homemade croutons floating on top. It also pairs well with a nice green salad for a lighter meal, or a sandwich for something heartier. And soup is always a great first course to a more formal meal.

If you haven’t made soup before, our Vegetarian Bean Soup is a great place to start. Begin by chopping your vegetables; while chopping, consider the size and texture in the finished soup. Potatoes tend to be soft when cooked, so leave them in slightly bigger pieces. Carrots hold their shape, so they will remain relatively unchanged, only softer. There are suggestions for the chopping of each vegetable in the recipe.

There are a few things that make making this vegetarian bean soup easier. The first is a slow cooker, of course.  You’ll need one that’s at least 6 quart. You’ll also want a crockpot liner. These just make cleanup oh so much easier. A good knife set is another kitchen must have. This is a decent set of knives if you’re just starting your kitchen journey.  If you want to splurge, I recommend these kitchen knives in a block.

Tips and Tricks

You can use boullion cubes and water for the stock, but a better choice is to use one of the prepared stocks available at the store. They depend on the real food ingredients for flavors, whereas boullion tends to rely on salt for its flavor. You can even make and use homemade stock, but it is a long process if you are just learning to make soup. Homemade stock is a recipe for another day.

The vegetarian bean soup recipe calls for fresh green beans, but it’s definitely fine to use frozen ones. As a bonus, you can get frozen green beans that are already cut into bite size pieces. I call that a win.

As this is a vegetarian recipe, there is no meat. We have added beans to help give our soup a little more substance. Add a can or two of whatever beans you like. You can use  white beans, pinto beans, chickpeas, or a handful or two of dry lentils added with the vegetables. Chili beans with their little bit of spice would be a good choice, too.

If you aren’t vegetarian, you won’t miss the meat in our soup. But if you want a meat-based soup, feel free to use our Vegetarian Bean Soup recipe as a jumping off point, and add some bite sized chicken, beef or sausage to your soup. Ham is also a great option. Cut it into ½ inch pieces and add about 1 to 1 ½ cups with the vegetables.

Frequently Asked Questions

How long does this soup last?

Our slow cooker vegetarian bean soup will keep for 4 or 5 days in the fridge, or about 3 months in the freezer. Heat frozen soups to boiling before eating.
