Lemon Chicken Rice Soup is a light, nourishing soup that comforts without added fat. At about 131 calories (1 freestyle point) per serving, it’s a gentle, protein-rich option with a silky texture.

This soup works especially well for people on a low-fiber or low-residue diet because it uses gently cooked, low-fiber vegetables such as peeled carrots and peeled celery, plus tender spinach. Each serving delivers around 10 grams of protein and a smooth, easy-to-digest consistency.
To deepen the flavor, simmer the chicken broth briefly with a sprig of fresh thyme before adding the vegetables and rice. Strain the broth to remove the thyme so the soup remains smooth and free of herb bits. I added baby spinach at the end for color and an extra nutrient boost.

The soup’s creamy body comes from cooking medium-grain rice directly in the broth; the rice breaks down slightly and thickens the liquid. A classic egg-and-lemon technique provides the velvety finish: whisk the eggs with lemon juice, then temper them by whisking in a ladle of hot broth before adding the egg mixture back into the pot. This two-step method prevents the eggs from scrambling and keeps the texture smooth and silky.
