Why this high protein lentil soup is different
Lentil soup is one of the most comforting meals you can make. It is also one of the cheapest. But most lentil soup recipes are not as high in protein as people think.
We reviewed the most popular lentil soup recipes in the United States. Most land between 13 and 20 grams of protein per bowl. That is decent, but it falls short of the 25 to 30 grams per meal that research suggests is best for maintaining muscle as we age (source).
We pushed this soup well past that number in three simple ways.
More lentils per bowl. Two full cups of dry red lentils go into the pot. Red lentils have about 24 grams of protein per 100 grams dry, based on USDA data (source).
Browned chicken sausage. A 12 ounce package of fully cooked chicken sausage adds savory flavor and about 12 grams of protein per bowl.
A Greek yogurt swirl. A spoonful on top adds creaminess, tang, and another 3 grams of protein.
| Per bowl | Typical lentil soup | This soup |
|---|---|---|
| Protein | 13 to 20 g | 38 g |
| Fiber | 8 to 15 g | 10 g |
| Cook time | 45 to 60 min | 40 min |
| Freezer friendly | Yes | Yes |
| Vegetarian option | Often | Yes, with tofu |
Why lentils are great for women in midlife
Lentils are one of the best foods you can add to your weekly rotation after 40. They combine protein, fiber, and minerals in one inexpensive package.
Protein for muscle. The PROT-AGE expert group recommends 1.0 to 1.2 grams of protein per kilogram of body weight per day for healthy older adults (source). Pulses like lentils make that easier and cheaper.
Fiber for fullness and heart health. Each bowl of this soup has about 10 grams of fiber. The Dietary Guidelines for Americans note that most adults fall short on fiber (source).
Iron and potassium. A bowl provides about 8 milligrams of iron and more than 1,700 milligrams of potassium. Potassium helps balance the effect of sodium on blood pressure (source).
Support during menopause. A 2024 review of nutrition in perimenopause and menopause highlights plant foods, fiber, and enough protein as important parts of a healthy pattern for this stage (source). A review in Nutrients also links legume-rich diets with better heart and metabolic health in menopausal women (source).
Ingredients for high protein lentil soup
Red lentils. They cook in about 20 minutes and break down into a thick, creamy soup without a blender. Rinse them first to remove dust. Brown or green lentils hold their shape and take about 10 minutes longer.
Chicken sausage. Use a fully cooked variety, such as chicken apple or Italian style. Slice it into coins and brown it first for the best flavor. Look for a lower-sodium brand, since sausage is the saltiest ingredient here.
Onion, carrots, and celery. This classic base adds sweetness and depth. Frozen diced mirepoix mix saves time.
Garlic and spices. Cumin, turmeric, and smoked paprika give warm flavor and a golden color.
Crushed tomatoes. They add body and a little acidity. Fire-roasted crushed tomatoes add a nice smoky note.
Low-sodium broth. Regular broth can contain 800 milligrams of sodium or more per cup. Choosing low sodium lets you control the salt.
Spinach and lemon. Stir them in at the end. The lemon brightens the whole pot.
Greek yogurt. Plain nonfat Greek yogurt adds a cool, creamy finish. Sour cream works but adds less protein.
How to make high protein lentil soup
- Brown the sausage. Heat the oil in a large pot over medium-high heat. Brown the sausage coins for 4 to 5 minutes, then move them to a plate.
- Cook the vegetables. Add the onion, carrots, and celery to the same pot. Cook for 6 minutes, until softened.
- Bloom the spices. Stir in the garlic, cumin, turmeric, and paprika and cook for 1 minute until fragrant.
- Simmer the lentils. Add the lentils, tomatoes, and broth. Bring to a boil, then simmer for 18 to 22 minutes, stirring now and then.
- Finish. Return the sausage, stir in the spinach and lemon juice, and season to taste.
- Serve. Ladle into bowls and top each with a spoonful of Greek yogurt.

Tips for the best lentil soup
Stir often near the end. Red lentils thicken quickly and can stick to the bottom of the pot. Stir every few minutes during the last 10 minutes.
Adjust the thickness. If the soup gets too thick, add a splash of broth or water. If it is too thin, simmer uncovered for 5 more minutes.
Season at the end. Sausage and broth both contain salt. Taste before adding more.
Use the acid. Lemon juice is not optional. It wakes up the earthy lentils and makes the soup taste lighter.
Blend half for extra creaminess. For a smoother soup, blend about a third of it with an immersion blender before adding the sausage back in.
Vegetarian and vegan options
This soup is easy to make without meat. Here are the best swaps. Each option keeps the soup filling, though protein drops a little when you skip the chicken sausage, so pair it with a protein-rich side.
| Version | Swap | Protein per bowl |
|---|---|---|
| Original | Chicken sausage, chicken broth, Greek yogurt | 38 g |
| Vegetarian | 14 oz firm tofu, vegetable broth, Greek yogurt | About 32 g |
| Vegan | 14 oz firm tofu, vegetable broth, unsweetened soy yogurt | About 30 g |
| Lighter | Skip sausage, add extra cup lentils | About 30 g |
For the tofu version, press a 14 ounce block of firm tofu and cut it into small cubes. Brown the cubes in the oil until golden, then follow the recipe the same way. Firm tofu made with calcium sulfate also adds calcium.

How to store and freeze lentil soup
Lentil soup is one of the best soups for meal prep. The flavor gets deeper after a day in the fridge.
Refrigerator. Cool the soup, then store it in airtight containers. Eat within 3 to 4 days, as USDA food safety guidance recommends for cooked leftovers (source).
Freezer. Freeze the soup without the yogurt for up to 3 months. Leave an inch of space at the top of each container because soup expands as it freezes.
Reheating. Thaw overnight in the fridge or reheat from frozen over low heat. Bring the soup to a full simmer, or 165°F, before serving. Add a splash of water because lentils keep absorbing liquid.
Cool it fast. For big batches, divide the hot soup into shallow containers so it cools quickly. Refrigerate within 2 hours of cooking.
Flavor variations to try
Once you know the base method, you can take this soup in many directions. Each version keeps the protein close to the original.
Moroccan style. Add 1 teaspoon of cinnamon and 1 teaspoon of ground coriander with the other spices. Finish with chopped cilantro and a squeeze of lemon.
Italian style. Use Italian chicken sausage, skip the cumin and turmeric, and add 1 teaspoon of dried oregano and a pinch of red pepper flakes. Stir in kale instead of spinach.
Curry style. Replace the paprika with 1 tablespoon of curry powder. Swap half the broth for light coconut milk and finish with lime instead of lemon.
Smoky chipotle. Add 1 minced chipotle pepper in adobo and use fire-roasted tomatoes. Top with Greek yogurt and a few pumpkin seeds.
Lemon and herb. Skip the tomatoes and add an extra cup of broth. Finish with plenty of lemon, dill, and parsley for a lighter, brighter soup.
Is high protein lentil soup budget friendly?
Yes. Lentils are one of the cheapest protein foods in the grocery store. A one-pound bag of dry red lentils often costs about the same as a single coffee shop drink and makes more than one full pot of soup.
Chicken sausage is the most expensive ingredient. To stretch your budget, use half a package and add an extra half cup of lentils. You will still get about 32 grams of protein per bowl.
Buying broth in large cartons, using frozen spinach, and choosing store brands all lower the cost further. This makes the soup a smart choice when food prices are high.
Common mistakes to avoid
These small mistakes are the most common reasons a lentil soup turns out bland, mushy, or too thick. Each one is easy to fix.
Skipping the browning step. Browning the sausage first adds flavor to the whole pot. It only takes 5 minutes.
Adding salt too early. The soup reduces as it simmers, so the saltiness concentrates. Wait until the end to season.
Cooking spinach too long. Add it in the last minute so it stays bright green.
Boiling hard. A rolling boil can make lentils stick and burn. Keep the pot at a gentle simmer.
What to serve with lentil soup
One bowl is a full meal, but these sides round it out. Pick one that adds crunch or freshness to balance the soft, hearty texture of the soup.
- Crusty whole-grain bread. A slice adds fiber and is great for dipping.
- A simple salad. Greens with lemon and olive oil balance the richness.
- Roasted vegetables. Broccoli or cauliflower roasted at 425°F adds crunch.
- Cottage cheese toast. For an even bigger protein boost, top toast with cottage cheese and tomatoes.
How this soup fits a high-protein day
At 38 grams of protein, one bowl covers close to half of the daily needs for many women. A woman who weighs 150 pounds and aims for 1.2 grams per kilogram needs about 82 grams of protein per day.
Here is an easy day built around this soup:
- Breakfast: High-protein overnight oats with Greek yogurt
- Lunch: Greek chicken meal prep bowls
- Dinner: A bowl of this high protein lentil soup
- Dessert: Chocolate cottage cheese mousse

Frequently asked questions
Is lentil soup high in protein?
Lentils are high in protein for a plant food, but many lentil soups give only 13 to 20 grams per bowl. This recipe adds chicken sausage and Greek yogurt to reach about 38 grams per bowl. That puts it above the 25 to 30 grams per meal that research suggests for older adults.
Which lentils have the most protein?
Red, green, brown, and black lentils all have similar protein, about 24 to 25 grams per 100 grams dry. Red lentils cook fastest and make the creamiest soup. Green and brown lentils hold their shape better if you prefer a chunkier soup.
Do I need to soak lentils before making soup?
No. Lentils do not need soaking. Just rinse them in a strainer and pick out any small stones. Unlike dried beans, they cook in about 20 to 25 minutes straight from the bag. Old lentils may take a few minutes longer, so taste them before you turn off the heat.
Can I make this lentil soup in a slow cooker?
Yes. Brown the sausage first, then add everything except the spinach, lemon, and yogurt to the slow cooker. Cook on low for 6 to 7 hours or high for 3 to 4 hours. Stir in the spinach and lemon at the end. Add the Greek yogurt to each bowl right before serving.
Can I make it in an Instant Pot?
Yes. Use the sauté setting to brown the sausage and vegetables. Add the lentils, tomatoes, and broth and cook on high pressure for 8 minutes. Let the pressure release naturally for 10 minutes. Stir in the spinach and lemon after opening the lid.
Why did my lentil soup get so thick?
Lentils keep soaking up liquid as they sit. Add broth or water when reheating until the soup reaches the thickness you like. Start with 1/4 cup of liquid per bowl and stir well. Taste again after reheating, since you may need a pinch more salt or a squeeze of lemon.
Is lentil soup good for menopause?
Lentils are rich in protein, fiber, iron, and potassium. These nutrients support muscle, heart, and digestive health, which all matter during menopause. Lentil soup is a satisfying, budget-friendly choice for this stage of life. Talk with your clinician if you have a health condition that limits protein or potassium.
