What Do You Put in Homemade Vegetable Soup? 

In the realm of vegetable soup, we’re not just sticking to the basics; we’re turning up the flavor dial! This recipe boasts all the classic veggie stars, plus a few secret ingredients that take it from good to downright delicious. Easily find all the ingredients at your local grocery store.

  • Onion – Use a large white or yellow onion. 
  • Olive Oil – This sautés the onion, creating a sweet taste. We also use it as a garnish for a boost of healthy fats and rich flavor. 
  • Carrots – Large, whole carrots will have the best taste, but baby carrots will also work if that’s what you prefer. 
  • Celery – Adds a slightly spicy-sweet flavor and extra texture. 
  • Potatoes – Russet potatoes or gold potatoes are best. Make sure to peel them first! 
  • Green Beans – You can use fresh, frozen, or canned. Just thaw and drain them before adding them to the soup.
  • Canned Diced Tomatoes – Used to add volume to the broth without diluting the flavor.
  • Herbs and Spices – You’ll need a bay leaf, dried oregano, dried thyme, and salt. We also like to use chopped parsley as a garnish for a bright, peppery finish. 
  • Stock – Use vegetable stock or chicken stock to form the base of the broth. Chicken broth or vegetable broth will also work.
  • Green Chilies – Technically optional, these add just a touch of heat. It takes this crockpot potato soup to a whole new level of deliciousness!

Common Questions About This Crockpot Vegetable Soup Recipe

How long does it take for potatoes to get soft in a crockpot on high? 

It typically takes between four and six hours for potatoes to soften in a slow cooker or crockpot when cooked on high. The exact time depends on the type of potatoes used and their size.

Should I soak potatoes in water before making soup? 

Yes, soak the potatoes in cold water before adding them to the soup to remove excess starch. This helps them cook evenly and prevents the soup from becoming mushy. 

How do I prevent my soup from getting gummy? 

Typically, soup becomes gummy when potatoes release too much starch.

Do I have to peel the potatoes? 

We recommend peeling the potatoes for a smoother texture, but you don’t have to! 

Can I make this slow cooker vegetable soup vegan? 

Yes! Just make sure to use vegetable stock, and omit the cheese for topping. Or, swap it out for a vegan cheese instead. 

Can I add protein?

Yes! To make this soup even more filling, add in stew meat, ground beef, or ground turkey. 

What else can I add to this recipe?

Feel free to mix in thawed and drained frozen vegetables, white beans, bay leaves, and fresh herbs to spruce up the flavor even more.

  1. In one section you refer to using tomato paste (which I LOVE for its richness) and then in the actual recipe you use 28oz of whole tomatoes. One or the other or both? Let me know!

    1. Hi Lauren! Sorry about that – it should just be the tomatoes. We updated the post. Thanks for catching that!
