Why You’ll Love This High Protein Cabbage Lentil Soup
There are plenty of lentil soup recipes on the internet, but this one stands out for a few simple reasons:
- Seriously high in protein. Most cabbage soups barely break 8 grams of protein per serving. This version doubles that, with roughly 18 grams per bowl — enough to count as a proper high-protein meal.
- One pot, minimal cleanup. No fancy equipment, no multi-step process. Chop, sauté, simmer, eat.
- Budget-friendly. Cabbage, lentils, carrots, and onions are among the cheapest ingredients at any grocery store. The whole pot costs less than a single takeout salad.
- Meal-prep hero. It tastes even better the next day, and it freezes beautifully for up to 3 months.
- Naturally vegan and gluten-free. No dairy, no meat, no gluten — just whole-food ingredients everyone at the table can enjoy.
Serve it steaming hot with a squeeze of lemon and fresh herbs.
Is Cabbage Lentil Soup Actually High in Protein?
Short answer: this one is. Most cabbage soups are mainly water and vegetables, which is why they leave you hungry. The difference here is the red lentil to vegetable ratio.
One cup of cooked red lentils contains about 18 grams of protein — more than three eggs. This recipe uses two full cups of dried red lentils, which triple in volume as they cook. Across six servings, the lentils alone contribute roughly 15 grams of protein per bowl, with the cabbage, carrots, and broth adding another 2 to 3 grams. That is approximately 18 grams of protein per serving, plus 13 grams of fiber.
Most cabbage lentil soup recipes online land between 8 and 12 grams of protein because they use half the lentils. If you want a soup that supports muscle maintenance and actually controls appetite, the lentil quantity is everything. This is a true high protein lentil soup, not a vegetable soup with a few lentils floating in it.
Want even more? Stir Greek yogurt into each bowl (+5g protein) or sprinkle hemp seeds on top (+10g per 3 tablespoons).
Ingredients You’ll Need
You only need simple, affordable pantry staples for this red lentil cabbage soup. Here is what to gather:
- 2 tablespoons olive oil — for sautéing the aromatics
- 1 large yellow onion, diced — builds the savory base
- 3 cloves garlic, minced — do not skip this; it adds so much flavor
- 3 medium carrots, diced — natural sweetness that balances the cabbage
- 2 celery stalks, diced — classic soup aromatic
- 2 cups dried red lentils, rinsed — the protein powerhouse; red lentils break down into a creamy texture
- 5 cups shredded green cabbage (about half a medium head) — roughly chopped is fine
- 1 can (14.5 oz) diced tomatoes — adds brightness and depth
- 7 cups vegetable broth — use low-sodium so you can control the salt
- 1 teaspoon ground cumin — warm, earthy flavor that loves lentils
- 1 teaspoon smoked paprika — adds a subtle smokiness
- ½ teaspoon turmeric — for color and gentle warmth
- 1 teaspoon salt, plus more to taste
- ½ teaspoon black pepper
- 2 tablespoons fresh lemon juice — stirred in at the end; it wakes up all the flavors
- Fresh parsley or cilantro, chopped — for serving
A note on lentils: Red lentils are the best choice here because they cook fast (about 20 minutes) and melt into a thick, creamy soup. Brown or green lentils also work, but they hold their shape and need about 10 extra minutes of simmering — the soup will be a bit more brothy and less creamy.
Everything you need: cabbage, red lentils, carrots, aromatics, and warm spices.
How to Make High Protein Cabbage Lentil Soup
This is a true one-pot recipe. Here is the step-by-step method:
Step 1: Sauté the aromatics. Heat the olive oil in a large soup pot over medium heat. Add the onion, carrots, and celery. Cook 6 to 8 minutes, stirring occasionally, until softened.
Step 2: Bloom the garlic and spices. Add the garlic, cumin, smoked paprika, and turmeric. Stir constantly for 1 minute until fragrant. Toasting spices in oil like this deepens their flavor far more than just stirring them into broth.
Step 3: Add everything else. Stir in the rinsed red lentils, cabbage, diced tomatoes with their juices, and vegetable broth. Add the salt and pepper, and make sure no lentils are stuck to the bottom.
Step 4: Simmer. Bring to a boil, then reduce to low, cover, and simmer 22 to 25 minutes, stirring once or twice. It is done when the lentils have broken down and the cabbage is silky. Red lentils dissolve as they cook, naturally thickening the broth — no flour or cream needed.
Step 5: Finish with lemon. Off the heat, stir in the lemon juice. Taste and adjust salt and pepper. The acidity brightens the whole pot and keeps the soup from tasting flat.
Step 6: Serve. Ladle into bowls, top with fresh herbs, and serve hot with crusty bread.
Total time: 10 minutes prep + 30 minutes cook = 40 minutes. Servings: 6 generous bowls.
Let it simmer until the red lentils melt into a thick, creamy broth.
Tips for the Best Cabbage Lentil Soup
- Rinse your lentils. A quick rinse removes dust and any tiny stones. Thirty seconds, always worth it.
- Do not cut the simmer short. If the soup looks thin at 20 minutes, give it 5 more. Red lentils need the full time to break down and create that creamy body.
- Shred the cabbage thinly. Thin shreds melt into the soup; thick chunks stay crunchy and dominate each bite.
- Season at the end. Broth saltiness varies by brand, so season lightly at first and finalize after the lemon juice goes in.
- Adjust the thickness. Simmer uncovered for the last 5 minutes for extra-thick soup, or stir in another cup of broth for a brothier bowl.
- Do not skip the lemon. Acid is what separates good lentil soup from great lentil soup. Apple cider vinegar works in a pinch.
Easy Variations to Try
Coconut curry version. Swap the cumin and paprika for 2 tablespoons of red curry paste and replace 2 cups of broth with canned coconut milk. Finish with lime juice instead of lemon.
Smoky chipotle. Add 1 to 2 minced chipotle peppers in adobo sauce with the garlic. The smoky heat pairs beautifully with the sweet cabbage and carrots.
Extra-protein chicken version. Add 1 pound of diced chicken breast with the broth and simmer until cooked through, then shred it back into the pot. This pushes each serving past 30 grams of protein.
Instant Pot method. Sauté steps 1–2 on the sauté function, add everything except the lemon juice, and pressure cook on high for 8 minutes with a 10-minute natural release. Stir in the lemon juice at the end.
How to Store, Freeze & Meal Prep
The flavors deepen overnight, and the texture holds up for days — this soup was made for meal prep.
Refrigerator: Store in airtight containers for up to 5 days. It thickens as it sits, so stir in a splash of water or broth when reheating.

Frequently Asked Questions
How much protein is in cabbage lentil soup?
It depends on the recipe. Many versions contain only 8 to 10 grams per serving. This recipe delivers approximately 18 grams per bowl thanks to 2 full cups of dried red lentils — roughly the protein of three eggs, completely plant-based.
Can I use brown or green lentils instead of red lentils?
Yes, but the result differs. Brown and green lentils hold their shape, so the soup will be brothier and less creamy, and they need 30 to 35 minutes of simmering. Protein content stays roughly the same.
Is this soup vegan and gluten-free?
Yes to both — no dairy, meat, or gluten anywhere in the recipe. Just check that your vegetable broth is certified gluten-free if cooking for someone with celiac disease.
Can I freeze cabbage lentil soup?
Absolutely, for up to 3 months. Red lentil soups freeze better than most: no dairy to split, no pasta to turn mushy. Cool completely before freezing and reheat gently with a splash of broth.
Why is my lentil soup bland?
Almost always: acid and salt. Lentils and cabbage are mild and need bold seasoning. Bloom the spices in oil, salt adequately, and add the lemon juice at the end — then taste again. The difference is dramatic.
