This soup came from my website, Perry’s Plate, and used to call for rice, corn, beans, and barley. It was a staple, and everyone in my family (including my extended family) loves it. After swapping out the grains and legumes with more nutritious alternatives, it’s still super tasty, is more colorful, and is a perfect way to use fresh summer vegetables!

More Recipes You'll Love
Southwest chicken and summer vegetable soup is a slow cooker pot of shredded chicken, peppers, zucchini, and Swiss chard in a smoky tomato-chili broth. Green chilies and chipotle powder give it gentle heat that builds as it cooks. Lime and cilantro stirred in at the end make the whole pot taste freshly made.
Pro Tips
- Leave the chicken breasts or thighs whole in the slow cooker and shred them at the end. Pre-cubed chicken dries out over the long cook; whole pieces stay juicy.
- Use the chard stems as well as the leaves. Diced and simmered all day, they go tender and sweet — nothing needs to go to waste.
- If the soup tastes acidic after the lime, stir in two tablespoons of honey. It rounds off the tomatoes without making the soup taste sweet.
- Do not skip the avocado garnish. The cool, creamy dice against the smoky broth is what makes each bowl feel complete.
Frequently Asked Questions
Can I make this soup on the stovetop?
Yes. Simmer the chicken gently for about twenty minutes, shred it, then add the vegetables for another twenty. It will lack the all-day depth but still tastes wonderful.
How spicy is this soup?
Mildly spicy from the green chilies and chipotle. The heat is warm and smoky rather than sharp — adjust the chipotle powder up or down to taste.
Can I freeze southwest chicken soup?
It freezes very well for up to three months. Freeze without the avocado garnish and add fresh avocado when you reheat and serve.
