Low carb soup recipes can provide volume while keeping protein central. This lemon chicken soup uses browned thigh pieces, zucchini, spinach, cauliflower rice, and dill in a clear broth. The vegetables enter in stages, so the bowl stays bright and textured rather than becoming uniformly soft.
Lemon is staged too. Zest blooms with onion and garlic, while juice joins after the pot leaves the burner. That captures citrus aroma without making the broth taste flat from a long simmer. A small egg-and-lemon liaison adds body at the end, but tempering keeps it smooth and light enough for lunch. Expect 30.4g protein per serving, at 243 calories.
Why this works
- Focused cooking gives chicken thighs defined texture before lemon herb broth enters, keeping the protein recognizable instead of buried beneath the finish.
- zucchini and spinach receives a separate checkpoint, so its color and structure remain visible in the final lemon chicken spinach soup while unnecessary liquid cooks away.
- The practical target is opaque cooked chicken, zucchini with firm green edges, and a smooth broth after tempering. This physical cue is more dependable than a timer because pan width, ingredient temperature, and cut size vary.
Ingredients
- 1 1/2 pounds chicken thighs (680 g)
- 1 tablespoon olive oil (14 g)
- 1 yellow onion, diced (180 g)
- 3 garlic cloves, minced (9 g)
- 1 tablespoon lemon zest (6 g)
- 6 cups chicken broth (1440 g)
- 3 cups cauliflower rice (300 g)
- 2 medium zucchini, chopped (400 g)
- 3 cups baby spinach (90 g)
- 2 large eggs, beaten (100 g)
- 1/4 cup lemon juice (60 g)
- 2 tablespoons chopped dill (8 g)
- 1 teaspoon fine salt (6 g)
Ingredient notes
- Chicken thighs: Choose evenly sized pieces or portions so the stated cooking window remains useful. Blot wet surfaces before browning, since visible moisture must evaporate before color can develop.
- Zucchini and spinach: Keep the cuts substantial enough to survive the full method. Small or crowded pieces soften early and release water into the carefully built base.
- Lemon herb broth: Measure this component rather than pouring freely. Its job is to connect the main ingredients while leaving their shapes and colors easy to distinguish.
- Dill: Add this near the end for clear color and aroma. Long cooking flattens the fresh note that should contrast with the savory base.
- Salt and acidity: Season in stages and taste after concentrated ingredients have joined. Reduction changes the balance, so a final adjustment is more dependable than adding the entire amount at the beginning. Make that adjustment slowly because seasoning cannot be removed after it dissolves.
How to make Lemon Chicken Spinach Soup
Brown the chicken pieces
Heat oil in a Dutch oven over medium. Add chicken in one layer and leave the first sides in contact with the pot until golden. Turn, cook until the centers reach 165°F (74°C), and transfer to a bowl. Keep the browned residue for the broth. Pause at the visible cue before continuing, because the next addition changes moisture and surface contact.
Bloom the citrus base
Add onion to the pot and cook until translucent, scraping loose the golden patches. Stir in garlic and lemon zest just until fragrant. Pour in broth, bring it to a lively simmer, and add cauliflower rice. Cook until the small pieces are nearly tender. Pause at the visible cue before continuing, because the next addition changes moisture and surface contact.

Stage the green vegetables
Add zucchini and simmer until its center yields lightly but the green edge still looks firm. Return chicken and any collected juices. Fold in spinach only until the leaves collapse. Lower the burner so the surface moves gently rather than boiling hard. Pause at the visible cue before continuing, because the next addition changes moisture and surface contact.

Temper the lemon finish
Whisk eggs and lemon juice in a bowl. Slowly whisk in two ladles of hot broth, then stream the mixture back into the pot while stirring. Keep the soup below a boil until slightly silky. Add dill, taste for salt, and divide solids evenly before ladling broth. Pause at the visible cue before continuing, because the next addition changes moisture and surface contact.

Ingredients
Instructions
- Brown the chicken pieces. Heat oil in a Dutch oven over medium. Add chicken in one layer and leave the first sides in contact with the pot until golden. Turn, cook until the centers reach 165°F (74°C), and transfer to a bowl. Keep the browned residue for the broth.
- Bloom the citrus base. Add onion to the pot and cook until translucent, scraping loose the golden patches. Stir in garlic and lemon zest just until fragrant. Pour in broth, bring it to a lively simmer, and add cauliflower rice. Cook until the small pieces are nearly tender.
- Stage the green vegetables. Add zucchini and simmer until its center yields lightly but the green edge still looks firm. Return chicken and any collected juices. Fold in spinach only until the leaves collapse. Lower the burner so the surface moves gently rather than boiling hard.
- Temper the lemon finish. Whisk eggs and lemon juice in a bowl. Slowly whisk in two ladles of hot broth, then stream the mixture back into the pot while stirring. Keep the soup below a boil until slightly silky. Add dill, taste for salt, and divide solids evenly before ladling broth.
Notes
- Ingredient size affects timing, so favor even cuts while allowing naturally irregular arrangement.
- The decisive finished cue is opaque cooked chicken, zucchini with firm green edges, and a smooth broth after tempering; wait for it before adding the final garnish.
- Refrigerate for 4 days and reheat portions gently, keeping fresh dill separate until serving.

Tips
- Use a wide vessel when browning. Open surface area lets moisture escape and gives chicken thighs better contact instead of trapping it in a shallow pool.
- Watch the stated texture cue before moving forward: opaque cooked chicken, zucchini with firm green edges, and a smooth broth after tempering. A timer is a guide, but the visible state determines when the next ingredient belongs.
- Keep dill for the finish. Its color and aroma are most useful after the strongest heat has passed, not buried during the main cooking stage.
- Divide the protein first when portioning, then distribute vegetables and sauce. That simple order keeps the final serving from receiving mostly liquid or small scraps.
Substitution
Chicken breast can replace thighs when checked early to prevent dryness. Chopped kale may stand in for spinach, but it belongs in the pot with the zucchini. For a dairy note without cream, add a little feta to each bowl. Celery can replace cauliflower rice for a clearer broth. If egg tempering feels unnecessary, omit the eggs and increase lemon juice gradually after tasting the finished pot. Keep the same decisive checkpoint when making any swap.
Serving and storage
Ladle into warm bowls and finish with dill, black pepper, and a thin lemon slice placed at the rim rather than submerged. A cucumber salad or roasted green beans makes a crisp side. Keep grated Parmesan at the table for diners who want a saltier finish. Stir the pot from the bottom before every serving so chicken and cauliflower do not collect in the final bowls.
Storage
Refrigerate the cooled soup in covered containers for up to 4 days. Keep any cold garnish or separate sauce apart until serving, and reheat only the portion needed so the full batch does not cycle through repeated temperature changes. Warm gently until the center is hot, adding a small spoonful of water only if the sauce has tightened. Freeze the broth, chicken, and cauliflower base for up to 2 months, then add fresh zucchini, spinach, and lemon after thawing. Label containers with the date and cool components before closing the lids to limit trapped condensation.

Questions people ask
What is the most important checkpoint for this lemon chicken spinach soup?
Look for opaque cooked chicken, zucchini with firm green edges, and a smooth broth after tempering. That physical cue tells you the base has enough structure for the next step and is more dependable than adding ingredients solely because a timer ended.
Can I prepare the lemon chicken spinach soup ahead?
Yes. Complete the main cooked components, cool them before covering, and refrigerate for up to 4 days. Hold dill and any cold finishing element separately, then add them after reheating so their contrast remains clear.
