Cooking Method for Instant Pot Red Lentil Soup

Cooking this Instant Pot Red Lentil Soup is a breeze. With the sauté function, you can easily build flavors before the pressure cooking begins. Just follow these simple steps, and you’ll end up with a comforting bowl of deliciousness.
- First, using the sauté function, warm 3 tablespoons of olive oil on high in your Instant Pot. You want it to be hot enough to sizzle when you add the onion. Stir in the chopped onion along with a pinch of kosher salt. Cook until the onion is soft and translucent, about five minutes. This step is crucial as it builds the flavor base for your soup.
- Next, stir in the garlic and cook it for about one minute until fragrant. Then, add the tomato paste, ground cumin, kosher salt, ground turmeric, black pepper, and New Mexico chile powder. Stir frequently, cooking for about two minutes until everything is well combined, and the spices are aromatic.
- Now, add the chicken stock, canned tomatoes with their juices, and the red lentils. Don’t forget to include another tablespoon of olive oil for a rich finish. Stir everything together gently.
- Secure the lid on the Instant Pot and set it to cook on high pressure for six minutes. Once done, allow the pressure to release naturally for up to ten minutes. If the pressure doesn’t release by then, carefully release any remaining pressure manually.
- After releasing the pressure, open the lid and stir in the juice of half a lemon. Taste the soup and adjust with more salt and pepper as needed. The lemon juice should brighten the soup beautifully.
- To serve, divide the soup between two bowls for a main course or four bowls for a starter. Top each bowl with a dollop of Greek yogurt, a scattering of fresh mint leaves, and a sprinkle of sea salt for added flavor.
- Finally, serve the soup warm with some flatbread on the side for dipping. The bread pairs perfectly with the creamy soup, making for a delightful meal.
Things Worth Knowing
- Pressure Cooking: The Instant Pot cooks the lentils quickly, but be careful not to overcook them. They should be tender yet hold their shape.
- Spice Adjustment: Feel free to adjust the spices to your taste. If you like it spicier, add more New Mexico chile powder.
- Texture Preference: For a creamier texture, blend a portion of the soup and return it to the pot before serving.
- Ingredient Variations: You can add vegetables like carrots or spinach for extra nutrition and color.
