This simple lemony chicken soup has been my weeknight dinner savior when I want something nourishing yet light. The bright citrus notes transform a classic chicken soup into something special, while the spring vegetables add color, texture, and fresh flavor to every spoonful.
I first created this soup during that awkward transition between winter and spring when I craved something warming but lighter than winter stews. My family now requests it whenever anyone feels under the weather or just needs a comforting meal that won't weigh them down.
Ingredients
- Boneless skinless chicken breasts provide lean protein and the base flavor for the soup. Look for organic chicken if possible for the best flavor.
- Chicken broth forms the foundation of the soup. Use homemade for exceptional flavor or a high quality store bought option with minimal additives.
- Yellow onion creates an aromatic base. Choose firm onions with no soft spots for the cleanest flavor.
- Garlic cloves add depth and immune boosting properties. Fresh is absolutely essential here.
- Carrots offer sweetness and a pop of color. Choose firm, bright orange carrots for best flavor and nutrition.
- Zucchini provides a tender texture and mild flavor that absorbs the broth beautifully. Smaller zucchini tend to be sweeter and less watery.
- Fresh peas bring springtime sweetness and a burst of green. Fresh spring peas are ideal, but frozen work wonderfully too.
- Cherry tomatoes add bright acidity and beautiful color. Look for ripe, fragrant tomatoes for the most impact.
- Lemon juice and zest brings the signature brightness that makes this soup special. Always use fresh lemons, never bottled juice.
- Dried thyme complements the lemon and chicken beautifully. Crush it between your fingers before adding to release more flavor.
Step-by-Step Instructions
- Prepare the Aromatics
- Heat olive oil in a large Dutch oven or soup pot over medium heat. Add diced onions and cook for about 5 minutes until translucent and softened. Add minced garlic and cook for another 30 seconds until fragrant but not browned. This aromatic base builds the foundation of flavor for the entire soup.
- Poach the Chicken
- Add chicken breasts, chicken broth, water, and dried thyme to the pot. Bring to a gentle simmer, then reduce heat to maintain a bare simmer. Cook for about 15 minutes until chicken is cooked through and registers 165°F on an instant read thermometer. Remove chicken to a plate and let cool slightly before shredding with two forks. The gentle poaching keeps the chicken tender while infusing the broth with flavor.
- Add the Vegetables
- While the chicken cools, add carrots to the simmering broth and cook for about 5 minutes until starting to soften. Add zucchini and cook for another 3 minutes. Add peas and halved cherry tomatoes and cook for 2 minutes more. Adding vegetables in stages ensures each is perfectly cooked rather than some being mushy while others remain raw.
- Finish the Soup
- Return the shredded chicken to the pot. Add lemon juice, lemon zest, salt, and pepper to taste. Simmer for 2 more minutes to allow flavors to meld. The lemon brightens everything and brings all the flavors together in perfect harmony.
- Serve
- Ladle into warm bowls and garnish with fresh chopped parsley. The soup should be steaming hot with a fragrant aroma of lemon and herbs.

The lemon is truly the star ingredient here. I discovered the magic of adding both juice and zest completely by accident when preparing this for my sister who was feeling under the weather. What began as a standard chicken soup was transformed into something bright and special that she still asks for years later, even when perfectly healthy.
Make It Your Own
This soup welcomes substitutions based on what's in your refrigerator. Try spinach or kale instead of peas, celery in place of zucchini, or add fennel for a different aromatic dimension. The key is maintaining the balance of the broth with the lemon brightness. I sometimes add a parmesan rind to the simmering broth for extra umami depth, removing it before serving.
Storage and Reheating
This soup actually improves with time as the flavors meld together. Store in an airtight container in the refrigerator for up to 4 days. When reheating, do so gently over medium low heat until just simmering. The chicken will remain tender and the vegetables won't overcook. For longer storage, freeze portions in freezer safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.
Serving Suggestions
While delicious on its own, this soup pairs beautifully with a slice of crusty sourdough bread or a simple green salad dressed with olive oil and lemon juice. For a heartier meal, serve with a scoop of cooked farro or orzo stirred in just before serving. I often set out optional toppings like extra lemon wedges, red pepper flakes, or grated parmesan to let everyone customize their bowl.

Recipe FAQs
- → Can I use rotisserie chicken instead of raw chicken breasts?
Absolutely! Using pre-cooked rotisserie chicken is a great time-saver. Simply shred about 2 cups of meat and add it during the last 5-10 minutes of cooking, just long enough to warm through. This modification reduces your cooking time by about 15 minutes.
- → How can I make this soup more filling?
To create a heartier meal, consider adding cooked pasta (like orzo or small shells), rice, or quinoa. You could also include cannellini beans or chickpeas for extra protein and fiber. Just remember to adjust the broth quantity as these additions will absorb liquid.
- → What's the best way to store leftovers?
Cool the soup completely before transferring to airtight containers. It will keep in the refrigerator for 3-4 days. For longer storage, freeze portions for up to 3 months. When reheating, you may need to add a splash of broth or water as the vegetables and chicken will have absorbed some liquid.
- → Can I use different vegetables based on what's in season?
This soup is extremely adaptable to seasonal produce. In summer, try yellow squash and green beans. For fall, butternut squash and kale work beautifully. Winter versions can include parsnips and cabbage. Just adjust cooking times accordingly—harder vegetables need longer to cook than tender ones.
- → Is this soup gluten-free?
Yes, as written, this soup is naturally gluten-free. However, always check your chicken broth labels as some commercial brands may contain gluten or be processed in facilities with gluten-containing products. For those with severe sensitivities, use a certified gluten-free broth.
- → How can I make this soup vegetarian?
To create a vegetarian version, substitute vegetable broth for chicken broth and replace the chicken with extra-firm tofu (pressed and cubed) or a can of drained white beans. For deeper flavor in the vegetarian version, consider adding nutritional yeast or a parmesan rind to the broth while simmering.
