How To Make Red Lentil Soup With Lemon – Step-by-Step

1. Sauté the aromatics
   In a large pot, heat olive oil over medium heat. Add chopped onions and cook until soft, about 5 minutes. Add garlic, tomato paste, cumin, red pepper flakes, coriander (if using), salt, and pepper. Stir for 1–2 minutes until fragrant.
2. Add the lentils and carrots

Tips for the Perfect Homemade Red Lentil Soup Recipe

• Use red lentils only—not brown or green—as they break down quickly for a smooth texture.
• Rinse the lentils before using to remove debris and prevent foam.
• Don’t overblend if you like texture—blending just half creates a creamy base while keeping bits intact.
• Spice to taste: Adjust heat by increasing or decreasing red pepper flakes.
• Add lemon last: This preserves its brightness and balances the earthy flavors.

Common Mistakes to Avoid When Cooking Lentil Bean Soup

• Using too little liquid: Lentils absorb a lot of broth—add extra if needed.
• Skipping the spices: Red lentils are mild—don’t hold back on seasoning.
• Adding salt too early: This can toughen lentils. Add once they’re tender.
• Using old lentils: Fresh lentils cook faster and taste better. Store them in a cool, dry place.
