How to Make Hearty Slow Cooker Vegetable Soup

Prep the Ingredients: Start by dicing the onion, slicing the carrots and celery, and chopping the potatoes and zucchini into uniform pieces for even cooking.
Combine in Slow Cooker: In your slow cooker, add the prepared onion, carrots, celery, diced potatoes, zucchini, marinara sauce, rinsed beans, and vegetable broth. Sprinkle in the Italian seasoning, salt, and black pepper, then give everything a good stir to mix.
Cook: Cover and set your slow cooker on low for about 6-7 hours or high for 3-4 hours. You’ll know it’s done when the vegetables are tender and your kitchen is filled with an inviting aroma.
Add Optional Vegetables: If you’re using green beans or peas, stir them into the soup in the last 15-20 minutes of cooking to keep them bright and vibrant.
Taste and Adjust: Before serving, taste your soup and adjust the seasoning as needed. A little extra salt or a dash of pepper might enhance the flavor perfectly.

Storing & Reheating

To store your Hearty Slow Cooker Vegetable Soup, let it cool to room temperature, then transfer it to an airtight container. It can stay in the refrigerator for up to 4 days.

Be aware that the texture may change slightly upon reheating, but adding a splash of vegetable broth can refresh it beautifully.
