Step-by-Step Instructions
Preparation and Cooking Steps
1. Sautéing vegetables and aromatics
Heat 2 tablespoons of olive oil in a large pot over medium heat. Once the oil is hot, add 1 medium, finely diced onion, 2 diced carrots, and 2 diced celery stalks. Cook for 5-7 minutes. Stir often. The veggies should be soft and the onion see-through. Then, add 3 minced garlic cloves and cook for 1-2 minutes. Keep stirring until the garlic smells good, but do not let it brown.
2. Adding lentils and liquids
Next, add 1 cup of rinsed green or brown lentils to the pot. Pour in a can of diced tomatoes with their juices. Add 6 cups of vegetable broth. Then, sprinkle in 1 teaspoon of ground cumin, 1 teaspoon of smoked paprika, 1/2 teaspoon of turmeric, and 1/2 teaspoon of black pepper. Add salt to taste. Stir everything well. Bring the mix to a boil over high heat.
3. Simmering the soup
Once it is boiling, turn the heat down to low. Cover the pot and let it simmer for 25-30 minutes. The lentils should be tender but still hold their shape. Stir occasionally to stop it from sticking to the pot. After 30 minutes, add 2 cups of chopped spinach or kale. Cook for another 3-5 minutes. The greens should wilt and blend in. Just before serving, squeeze the juice of 1 fresh lemon into the soup. Taste and adjust the seasonings as needed. Finally, serve the soup hot, garnished with fresh parsley.
Tips & Tricks
Flavor Enhancement Ideas
To boost your soup's flavor, you can adjust spices and seasonings. Start with the cumin and smoked paprika. If you like heat, add a dash of cayenne pepper. For a sweeter taste, try a pinch of cinnamon. Fresh herbs also add a nice touch. Consider thyme or bay leaves during cooking.
Cooking techniques matter too. Sauté your onion, carrots, and celery until soft. This step builds a flavor base. Don’t rush the garlic; cook it just enough to release its aroma. Stir it in after the veggies. When you add the broth and lentils, let it come to a boil. Then, reduce the heat to let it simmer. This slow cook helps flavors blend well.
Lastly, finish the soup with lemon juice just before serving. This brightens the taste and adds freshness. Enjoy experimenting with these tips to make your high-protein lentil soup truly your own!
Pro Tips
- Soak Lentils for Quick Cooking: Soaking lentils for an hour before cooking can reduce their cooking time and enhance their digestibility.
- Enhance Flavor with Herbs: Consider adding fresh herbs like thyme or bay leaves during cooking for an extra layer of flavor.
- Blend for Creaminess: For a creamier texture, blend a portion of the soup and stir it back in before serving.
- Serve with a Side: Pair the soup with a fresh salad or whole-grain bread to make it a complete and satisfying meal.

Dietary Adaptations
For those who follow a vegetarian or vegan diet, this soup fits perfectly. Lentils are a great protein source. They offer a hearty texture that satisfies. You can enjoy this soup without any meat or animal products.

When it comes to stock, you can swap vegetable broth for chicken broth. This change can add a richer taste. If you want to adjust the spices, feel free. Add more cumin or paprika for a bolder flavor. You can even mix in some chili powder for heat.
