Chicken and Lentil Soup: Easy, Hearty Recipe

Chicken and lentil soup combines tender chicken, soft lentils, vegetables and aromatic spices in one satisfying pot. It is a practical meal for a busy week because it uses accessible ingredients, reheats well and can be prepared in larger batches.

The lentils give the broth body while the chicken provides additional protein. Carrots, onions and tomatoes add flavor without requiring a complicated cooking process.

This recipe makes six generous servings and takes approximately 60 minutes from start to finish.

Recipe overview

The recipe uses dried lentils, not canned lentils. Instructions for using canned lentils appear below.

Ingredients for six servings

Use raw chicken breast for the stated cooking method. If using chicken thighs, adjust the cooking time and nutrition estimates.

Brown or green lentils are ideal because they hold their shape better than red lentils.

Check the lentil package for cooking instructions and remove any small stones or debris before rinsing.

Step-by-step instructions

1. Prepare the vegetables

Dice the onion, carrots and celery into small, roughly equal pieces.

Mince the garlic and chop the parsley.

Rinse the dried lentils thoroughly under running water.

Cut particularly thick chicken breasts into two large pieces so they cook more evenly.

Keep the chicken raw and refrigerated until it is time to add it to the pot.

2. Cook the aromatic vegetables

Heat the olive oil in a large heavy-bottomed pot over medium heat.

Add the onion, carrots and celery.

Cook for 6–8 minutes, stirring occasionally, until the onion softens.

Add the garlic, cumin, smoked paprika and thyme.

Cook for another 30–60 seconds, stirring continuously to prevent the garlic and spices from burning.

This step builds flavor before the liquid is added.

3. Add lentils, tomatoes and stock

Add the rinsed lentils, chopped tomatoes, chicken stock and bay leaves.

Stir well and bring to a gentle boil.

Reduce the heat to maintain a steady simmer.

Cook for approximately 10 minutes before adding the chicken.

Starting the lentils first helps synchronize the cooking times.

4. Add the chicken

Place the chicken breasts into the simmering soup.

They should be mostly submerged.

Continue cooking at a gentle simmer for approximately 15–20 minutes, depending on their thickness.

Check the thickest part with a food thermometer.

Chicken must reach a safe internal temperature of 74°C / 165°F.

Remove the chicken as soon as it reaches that temperature.

Do not rely only on color to determine whether poultry is cooked safely.

5. Finish cooking the lentils

Continue simmering the soup until the lentils are tender.

For many brown or green lentils, the total simmering time is approximately 25–40 minutes, but this varies by product and age.

Add 300–500 ml water as needed if the soup becomes too thick.

The final texture should be hearty but still spoonable.

6. Shred the chicken

Allow the cooked chicken to rest briefly.

Use two forks to shred it into bite-sized pieces.

Return the shredded chicken to the pot once the lentils are tender.

Heat gently for another 2–3 minutes.

Avoid prolonged boiling after the chicken has been shredded, which can make lean breast meat less tender.

7. Season and serve

Remove the bay leaves.

Add lemon juice and most of the chopped parsley.

Taste before adding salt because chicken stock can already contain substantial sodium.

Season with black pepper.

Divide the soup into six bowls and garnish with the remaining parsley.

For a thicker consistency, mash a small portion of the cooked lentils against the side of the pot and stir them back into the soup.

Estimated nutrition per serving

The following estimates are based on dividing the entire recipe into six equal servings.

They use typical food-composition values for raw chicken breast, dried lentils, vegetables and olive oil.

Actual values depend on the chicken, lentils, stock and ingredient brands.

The ranges are estimates rather than laboratory-tested values.

The cooked weight will also vary with evaporation and the amount of water added.

For accurate nutrition tracking, record the ingredients of the entire recipe and divide the total into six portions.

If you weigh the finished soup, you can calculate the nutrition per 100 g using its actual cooked weight.

Food composition data can be checked through USDA FoodData Central.

Which lentils work best?

Different lentils produce different textures.

Brown and green lentils are the best match for this recipe.

Red lentils are suitable if you prefer a smoother, thicker soup, but the cooking sequence should be shortened.

Canned lentils can also work. Drain and rinse them, then add them toward the end of cooking.

Because canned lentils already contain water, do not substitute the same weight of canned lentils for dry lentils without adjusting the quantities.

Can you use chicken thighs?

Yes.

Boneless, skinless chicken thighs produce a richer flavor and are more forgiving during cooking.

They usually contain more fat than chicken breast, so the calories and macronutrients will change.

Cook the thighs until they reach a safe internal temperature of 74°C / 165°F.

For especially tender shredded thigh meat, additional gentle cooking may be useful.

If using bone-in chicken, remove all bones before returning the meat to the soup.

How to make the soup thicker or thinner

For a thicker soup:

• Simmer uncovered for a few additional minutes.
• Mash a portion of the lentils.
• Blend one cup of soup and return it to the pot.
• Use slightly less added water.

For a thinner soup:

• Add warm stock or water in small amounts.
• Stir and reassess after each addition.
• Adjust seasoning after diluting the broth.

Lentils continue absorbing liquid while the soup stands.

Leftovers may therefore require additional water when reheated.

Flavor variations

Mediterranean-style chicken lentil soup

Use oregano, thyme, lemon and parsley.

Add chopped spinach near the end.

Warmly spiced version

Increase the cumin slightly and add a small amount of ground coriander.

A pinch of chili flakes adds heat.

Tomato-forward version

Add extra chopped tomatoes and reduce the added water slightly.

This produces a more pronounced tomato flavor.

Extra-vegetable version

Add zucchini, kale or green beans.

Include their weight when calculating nutrition.

Creamier texture without cream

Blend part of the cooked lentils with some broth and return the mixture to the pot.

This thickens the soup without requiring cream or flour.

Can you make chicken lentil soup in a slow cooker?

Yes, although timing depends on the appliance.

For a slow-cooker version:

1. Add vegetables, rinsed lentils, tomatoes, spices and stock.
2. Add raw chicken.
3. Cook according to your slow cooker's instructions until the lentils are tender.
4. Confirm the chicken reaches 74°C / 165°F.
5. Remove and shred the chicken.
6. Return it to the soup and season.

Avoid relying on a fixed time alone because slow cookers differ.

Use thawed chicken rather than frozen chicken unless your appliance's instructions explicitly support that method and food safety can be assured.

Can you use cooked chicken instead?

Cooked chicken is useful when you have leftovers.

Prepare the lentils and vegetables first.

When the lentils are tender, add approximately 450–500 g of already cooked, shredded chicken.

Heat the soup thoroughly.

Because the chicken is already cooked, it does not need the same simmering time as raw chicken.

Keep the amount of salt in mind if using rotisserie chicken.

Serving ideas

Chicken and lentil soup is substantial enough to serve as a meal on its own.

Depending on appetite and energy needs, you can add:

• Whole-grain bread.
• A simple green salad.
• Roasted vegetables.
• Plain yogurt with lemon and herbs.
• A small portion of cooked rice.

The soup already provides protein and carbohydrates, so accompaniments can be chosen according to the overall meal rather than a fixed rule.

Storage and reheating

This soup is suitable for batch cooking.

For safe storage:

1. Divide the soup into shallow containers.
2. Refrigerate promptly, within two hours of cooking.
3. Keep refrigerated at 4°C or below.
4. Consume refrigerated leftovers within 3–4 days.
5. Reheat thoroughly before eating.

For longer storage, freeze individual portions.

Allow frozen soup to thaw safely in the refrigerator or use another food-safe thawing method.

Add water or stock when reheating because lentils may absorb additional liquid.

Avoid leaving a large pot of soup to cool slowly at room temperature.

See the USDA guidance on leftovers and food safety.

Common problems and solutions

The lentils are still firm

Continue simmering and add liquid if necessary.

Older lentils or acidic ingredients can sometimes affect cooking time.

The chicken is dry

Avoid boiling it aggressively.

Check its internal temperature and remove it when safely cooked.

Shredded chicken should be returned near the end.

The soup is too watery

Simmer uncovered or mash some of the lentils.

The soup tastes bland

Check the salt level, then add lemon juice, herbs or a little extra spice.

The soup is too thick after refrigeration

Add water or stock while reheating.

This is normal because lentils continue to absorb liquid.

Shopping and portion planning

For six portions, the main ingredients are 600 g raw chicken breast, 240 g dried lentils and approximately 1.5 liters of stock.

For three portions, halve the quantities.

For twelve portions, double the ingredients and use a sufficiently large pot.

The amount of liquid may need adjustment depending on the pot size, cooking temperature and evaporation.

For consistent portions, weigh the finished soup and divide its total weight by six.
