How to Make Slow Cooker Vegetable Soup

Making this slow cooker vegetable soup is incredibly straightforward, even for beginners. You’ll be amazed at how easy it is to create such a delicious and healthy meal with minimal effort. This simple slow cooker vegetable soup recipe is designed to fit seamlessly into your busy life.

Step 1: Prep Your Veggies. Start by washing, peeling, and chopping all your fresh vegetables. This is the most hands-on part, but it’s crucial for even cooking and great texture. Dice the onion, mince the garlic, slice the carrots and celery, and dice the potatoes. Chop the red bell pepper and zucchini, and trim the green beans into bite-sized pieces.
Step 2: Layer the Slow Cooker. Drizzle the 2 tablespoons olive oil into the bottom of your slow cooker insert. Then, add the prepared onions, garlic, carrots, celery, potatoes, red bell pepper, zucchini, and green beans. Pour in the 1 (15-ounce) can diced tomatoes (undrained) and the 6 cups low-sodium vegetable broth. Sprinkle everything with the dried herbs: 1 teaspoon dried thyme, 1 teaspoon dried basil, and 1/2 teaspoon dried oregano, plus 1/4 teaspoon black pepper and 1 teaspoon salt.
Step 3: Slow Cook to Perfection. Cover the slow cooker and set it to cook on the Low setting for 7-8 hours, or on the High setting for 4-5 hours. The goal is for all the vegetables to become wonderfully tender and for the flavors to meld beautifully. You’ll notice a delicious aroma filling your kitchen as it cooks, signaling that this hearty slow cooker vegetable soup is coming together.
Step 4: Add the Finishing Touches. About 20 minutes before you’re ready to serve, stir in the 1 cup frozen peas and the 2 cups chopped fresh spinach or kale. Cover and let it cook for those final 20 minutes, just until the peas are heated through and the greens have wilted into the soup.
Step 5: Taste and Serve. Once everything is heated through, give the soup a taste. Adjust the salt and pepper as needed. For an extra burst of freshness, stir in the juice of 1/2 lemon. This step truly brightens up all the flavors, making this how to make slow cooker vegetable soup guide complete. Ladle this comforting soup into bowls and enjoy!

How to Store and Reheat Your Slow Cooker Vegetable Soup

Properly storing and reheating this delightful slow cooker vegetable soup ensures you can enjoy its comforting flavors for days. Once the soup has cooled slightly after cooking, transfer it into airtight containers. For the best quality, I recommend using glass or BPA-free plastic containers. This easy slow cooker vegetable soup storage method keeps it fresh in the refrigerator for 3 to 4 days. If you want to keep it even longer, this soup freezes beautifully for up to 3 months. Just make sure to leave a little headspace in your freezer-safe containers, as liquids expand when frozen.

Reheating is just as simple! For refrigerated soup, gently warm it in a saucepan over medium heat, stirring occasionally, until heated through. You can also reheat it in the microwave in 1-2 minute bursts, stirring between each. If reheating from frozen, thaw it overnight in the refrigerator first. Then, reheat using the stovetop or microwave method as described above. It’s that easy to enjoy this hearty soup anytime! For other comforting meals, check out our coconut chicken meatballs.
