Tips for the Best Lemon Chicken & Cauliflower Rice Soup

Use fresh lemon juice for the most vibrant flavor—bottled just doesn’t compare. Don’t overcook the cauliflower rice; it should stay fluffy, not mushy.

For extra creaminess, stir in a tablespoon of heavy cream or a pat of butter before serving.

And if you prefer more depth, toss in a Parmesan rind while simmering—it makes the broth irresistible.

Storage & Reheating

Store leftover soup in an airtight container in the refrigerator for up to 4 days. Reheat gently on the stove over medium-low heat.

You can also freeze the soup for up to 2 months—just thaw overnight in the fridge before reheating.
