The BEST Crock Pot Vegetable Soup is Right Here

This slow cooker vegetable soup recipe is bursting with hearty vegetables and is so simple to make. And, since it’s a dump-and-go recipe, you can make it without sautéing the vegetables first. Just chop, drop and go! The thing I love about this particular vegetable soup is that it reminds me of the kind out of a can that I ate growing up.

This version tastes quite similar to the old fashioned vegetable soup I grew up eating, except it’s packed with even more vegetables and has a much fresher flavor. It also makes amazing leftovers, and I love packing away a few portions for easy lunches that are ready to go in the freezer. And the good news is that making vegetable soup in the crockpot couldn’t be easier! 

In this recipe i’m using simple hearty vegetables that can stand up to a longer cook time, such as carrots, potatoes, and celery, along with flavorful diced tomatoes, tomato paste, and vegetable stock. Just add everything to a crockpot, cover, and cook on high or low. Then, add tender vegetables at the end, such as corn and peas, which don’t need a long cook time. Don’t forget to taste for seasoning and add additional salt to taste!

Testing Tips for Making the Best Vegetable Soup

  • Be sure to choose the right combination of vegetables for maximum flavor and color. I personally like a mix of hearty potatoes, carrots, celery, corn and peas. Then, kick up the flavor with a mix of herbs and spices. I also like smoked paprika for a mild smoky flavor, granulated garlic, as well as the addition of bay leaves.
  • Wondering about frozen vs. fresh vegetables? I recommend using fresh carrots, celery and potato – those work the best for this vegetable soup recipe. But frozen green beans, corn, and peas all work great.

Ingredient Notes

  • Carrot: Whole, fresh, chopped carrots yield the best flavor for this soup. You can use baby carrots if that’s what you have on hand, but they are typically not as sweet, and so I recommend whole-fresh-chopped if possible.
  • Potato: I like peeled Russet potatoes because they feel the most traditional, but waxy yellow, red or even sweet potatoes would also work well.
  • Green beans: Use fresh green beans, or frozen green beans that have been defrosted.
  • Fire roasted diced tomatoes: I like the smokey flavor of fire roasted tomatoes, but regular diced tomatoes will work well, too.
  • Tomato paste: Adds depth of flavor, so don’t skip it!
  • Bay leaves: While not absolutely necessary, bay leaves add extra flavor to the broth.
  • Smoked paprika: I love how it adds a nice smokey note to the finished soup. If you don’t have smoked, sweet paprika can be substituted.
  • Corn kernels: Use fresh or frozen corn that’s been defrosted.
  • Peas: Use fresh, or frozen peas that have been defrosted.
