💬 “Consistent beats perfect — and this soup is consistently one of the best things you can make on a Tuesday night.”

What Type of Lentils Should You Use?

All lentils work. But here's the quick breakdown:

• Red lentils — cook fastest (20 min), break down into a creamy texture
• Green or brown lentils — hold their shape, slightly heartier bite
• French lentils (Puy) — firm, earthy, great for chunky soup

Best pick for this recipe: Red lentils for a thick, creamy result. Green lentils if you like more texture.

No soaking needed. That's the deal. Lentils are built different — they go straight from bag to pot.

How to Make High-Protein Lentil Soup (Step-by-Step)

What You'll Need

Serves 4–6 | Prep: 10 min | Cook: 30 min

Ingredients:

• 1½ cups dry red lentils, rinsed
• 1 medium onion, diced
• 4 garlic cloves, minced
• 2 medium carrots, chopped
• 1 can (14 oz) diced tomatoes
• 6 cups vegetable broth (low sodium)
• 2 tsp cumin
• 1 tsp smoked paprika
• ½ tsp turmeric
• Salt and pepper to taste
• 2 tbsp olive oil
• 2 cups fresh spinach (optional but worth it)
• Juice of half a lemon

Optional add-ins for extra protein:

• 1 can chickpeas, drained
• A handful of hemp seeds stirred in at the end

Step-by-Step Instructions

Step 1: Sauté the base Heat olive oil in a large pot over medium heat. Add onion and carrots. Cook 5–6 minutes until softened. Add garlic and cook 1 more minute.

Step 2: Add the spices Stir in cumin, smoked paprika, and turmeric. Let them toast for 30 seconds. This step matters — it wakes the spices up.

Step 3: Add lentils, tomatoes, and broth Pour everything in. Stir to combine. Bring to a boil, then reduce heat and simmer uncovered for 20–25 minutes until lentils are fully soft.

Step 4: Adjust texture For a creamier soup, use an immersion blender to blend half the pot. Leave the rest chunky. Do the work, get the texture you want.

Step 5: Finish strong Stir in spinach and lemon juice. Taste and adjust salt. Done.
