Step-By-Step Instructions

This recipe is very simple, so no matter your cooking skill, you'll make a tasty soup. Once you chop all your vegetables, this soup comes together quickly.

First, preheat your olive oil in a large skillet over medium-high heat.

1. HEAT PAN. Heat your olive oil in a large skillet over medium-high heat.

2. COOK VEGGIES. Now, add chopped onions, carrots, and celery; cook for 4-5 minutes until soft.

ADD GARLIC and PARSLEY. Next, stir in garlic and parsley and cook for an additional 30 seconds.

3. ADD TO CROCKPOT. Remove the pan from the heat and place cooked veggies in the crock of your 6-quart, or larger, slow cooker.

4. ADD REMAINING VEGGIES. Add diced tomatoes, potatoes, green beans, zucchini, tomato paste, bay leaves, paprika, salt, thyme, basil, oregano, pepper, and vegetable broth to the crockpot.

Gently stir until ingredients are combined.

5. COOK. Place the cover on and cook on LOW for 6 hours, or cook on HIGH for 3 hours.

6. ADD CORN. If using, add the corn for the last 30 minutes of cooking.

7. DISCARD BAY LEAVES. When finished cooking, discard the bay leaf and add additional salt and pepper to your liking.

Place the soup into bowls and squeeze some fresh lemon juice over the top.

Recipe tips & tricks

• Make sure to dice your potatoes small to cook at the same rate as the softer vegetables in the soup. 
• Cut other vegetables into large pieces, so they don’t turn to mush while cooking. 
• Adjust the spice to your liking. See below for some flavor options.
• You can use fresh or frozen veggies in this crockpot veggie soup recipe. 
• For added protein, you can add a pound of cooked lean ground beef before cooking.
• This crock pot soup recipe is made for a 6-quart slow cooker.

Tip: When you know you're having a busy day, cut all your veggies the night before. You can even sauté your onions, carrots, and celery the night before. 

How to add flavor to vegetable soup

For some, the basic recipe for vegetable soup is just right. For others, it can be a little bland. If you'd like to punch up the flavor of your soup, here are our suggestions:

• ADD ADDITIONAL HERBS. Italian seasoning (basil, thyme, oregano) is an excellent match for this soup, so is celery salt and adding another bay leaf while cooking. Paprika is also delicious.
• GIVE IT A KICK. Try giving your vegetable soup a punch of flavor by adding red pepper flakes or some chopped jalapeño. 
• BRING ON THE CHEESE. Adding a bit of grated parmesan cheese on top adds a little saltiness and enhances the flavor. Or cook the veggie soup with a Parmesan cheese rind. 
• ADD SOME ACIDITY. You can do this by squeezing lemon juice into your finished soup. 

How long does it keep?

You can keep Crock Pot Vegetable Soup in an airtight container in the refrigerator for about five days. Reheat and enjoy again and again. 

We make it on a Sunday and have soup all week long!

To freeze:

Vegetable Soup that you make in a slow cooker definitely freezes well. 

Place your cooked soup in a freezer-safe container, or freezer-safe bag, label and date, and store in the freezer for up to 3 months. 

Tip: Quart or gallon-sized zippered freezer bags work well. Lay them flat to freeze, and then stack them in the freezer.

Follow our tips for preventing freezer burn.

To thaw, take the soup out of the freezer the day before you'd like to serve it.

Then, reheat either on the stovetop in a saucepan over medium heat for approximately 15 minutes or in the microwave for 1-2 minutes (longer if you have more than a serving of soup).
