Preparing homemade vegetable soup is quick and easy with the help of your slow cooker! Just prep the ingredients and toss them in the crockpot, then let the slow cooker do all the hard work for you. Follow these simple instructions to make your own vegetable soup at home.
How To Make Slow Cooker Vegetable Soup
Before you can start cooking your soup, you’ll need to take a few minutes to prep all the ingredients. Start by finely chopping your onion. Then, peel and dice the potatoes.
Add the onion and potato to the bowl of your slow cooker, along with the diced tomatoes, frozen mixed vegetables, minced garlic, Italian seasoning, and vegetable broth. Stir to mix all the ingredients together until they’re well combined.
Place the lid on top of the crockpot and set it to cook. You can cook the soup on low for 8 hours or high for around 5 to 6 hours. Before serving your vegetable soup, stir to combine all the ingredients together.
Soup Variations
In addition to customizing the type of vegetables you use in your own soup recipe, there are a variety of other ways you can change up this easy meal to make it your own! Try these other recipe ideas to create a delicious bowl of soup for your family.
- Add some meat. This recipe is a great option for a meat-free meal. But that doesn’t mean you can’t add some protein to it if you prefer to enjoy your soup with meat. Add diced chicken, stew meat, beef, ground beef, or ground turkey to the recipe.
- Mix in some beans. You can keep this a vegetarian meal and still add some extra protein to the recipe with the help of beans. A variety of beans would be delicious in this vegetable soup, including lima beans, kidney beans, pinto beans, and great northern beans.
- Stir in some pasta. Add a little hardiness to this vegetable soup recipe with the help of pasta. In the last hour of cooking, you can stir in your favorite pasta to give your soup even more depth. Small pasta noodles, like bow tie or elbow macaroni, are great for mixing into your soup recipe.
- Try different stocks. Using vegetable stock is a great way to keep the meal vegetarian. But if you’re not concerned about using animal products in your soup, you can easily swap out the vegetable stock for beef or chicken broth or stock instead.
Storing, Freezing, and Reheating
To store the leftovers, allow the soup to cool completely, then transfer it to an airtight container. You can keep the soup in the refrigerator for up to 3 days.
This vegetable soup recipe can also be frozen for more long-term storage. Once the soup has cooled completely, transfer it to a freezer safe container or freezer bag. Store the soup in the freezer for up to two months.
To reheat the soup, allow it to thaw in the refrigerator. Then, heat it up in the microwave or on the stovetop in a saucepan over medium heat.
Can I use fresh vegetables instead of frozen?
Yes, but depending on the type of vegetables you choose, you may need to adjust the cooking time, and you may want to sauté them before adding them to the slow cooker.
Can I add meat to this soup?
Ground beef is a great choice to add to the soup. Just cook and drain any fat and add it to the slow cooker with the other ingredients.
