Mastering the Basic Lentil Soup Recipe

This recipe provides a solid foundation for your Instant Pot lentil soup journey. We’ll cover the essential ingredients, cooking process, and tips for achieving the perfect texture and flavor.

Essential Ingredients for Lentil Soup

• Lentils: Brown or green lentils work best. Red lentils tend to get mushy in the Instant Pot. One cup of dry lentils yields a substantial pot of soup.
• Aromatics: Onion, garlic, and carrots form the flavor base. Diced celery adds another layer of complexity.
• Broth: Vegetable broth provides a rich, savory flavor. Chicken broth can also be used for a deeper taste. Water can be substituted in a pinch, but the flavor will be less pronounced.
• Spices: A simple blend of cumin, turmeric, and smoked paprika adds warmth and depth. Bay leaves infuse the soup with a subtle, aromatic note.
• Olive Oil: Used for sautéing the vegetables and adding richness.
• Lemon Juice/Vinegar: A splash of acidity brightens the flavors and balances the earthiness of the lentils.
• Salt & Pepper: To taste.

Step-by-Step Instant Pot Lentil Soup Instructions

1. Sauté the Aromatics: Turn on the Instant Pot to the “Sauté” function. Add olive oil and sauté the diced onion, carrots, and celery until softened, about 5-7 minutes. Add minced garlic and cook for another minute until fragrant.

2. Add Lentils & Spices: Stir in the lentils, cumin, turmeric, smoked paprika, and bay leaves. Cook for 1 minute to toast the spices.

3. Pour in Broth: Pour in the vegetable or chicken broth, making sure the lentils are fully submerged. Add salt and pepper to taste.

4. Pressure Cook: Secure the Instant Pot lid and set the valve to “Sealing.” Cook on “Manual” or “Pressure Cook” for 12 minutes for brown/green lentils or 8 minutes for split red lentils.

5. Natural Pressure Release: Allow the Instant Pot to naturally release pressure for 10-15 minutes. Then, carefully release any remaining pressure manually.

6. Adjust & Serve: Remove the bay leaves. Stir in lemon juice or vinegar. If desired, use an immersion blender to partially blend the soup for a creamier texture. Taste and adjust seasonings as needed. Serve hot with your favorite toppings.

Tips for the Best Texture & Flavor

• Don’t Overcook: Overcooked lentils can become mushy. The cooking time is crucial.
• Toast the Spices: Toasting spices before adding liquid enhances their flavor.
• Use High-Quality Broth: The quality of your broth directly impacts the flavor of the soup.
• Add Acidity: Lemon juice or vinegar brightens the flavors and balances the earthiness of the lentils.
• Don’t Skip the Natural Pressure Release: Allowing the pressure to release naturally prevents the lentils from exploding and becoming mushy.
