Slow Cooker Crockpot Summer Vegetable Soup
If you need a dinner that basically cooks itself, this slow cooker crockpot summer vegetable soup is it. It's loaded with fresh zucchini, carrots, green beans, and tomatoes, and it turns simple produce into something cozy and deeply flavorful. I love this recipe because it's light enough for warm days but still filling, and it makes amazing leftovers for quick lunches all week.
In the summer, it's especially popular because gardens and farmers markets are overflowing with zucchini, green beans, tomatoes, and peppers. This version lets you use all that fresh produce without heating up your kitchen.

How to Make Slow Cooker Summer Vegetable Soup

Step 3: Add the prepared vegetables to the bottom of the slow cooker (Image 3).
Step 4: Sprinkle the seasonings evenly over the top (Image 4).

Hint: if your zucchini tends to get too soft, add it during the last 60-90 minutes of cooking instead of at the beginning. It keeps a better texture that way.
Baking Schedule

💭Crucial Success Tips
Vegetables continue to soften in the slow cooker, even on warm. Once they're fork-tender, switch to warm or turn it off. Overcooking can make zucchini mushy and dull the fresh flavor.
