What is Vegan Lentil Soup?
Vegan lentil soup is a flavorful and hearty dish made primarily from lentils, vegetables, and seasonings, free from any animal-derived ingredients. This nourishing soup is a staple in many cultures around the world, with variations that highlight local ingredients and flavors. The core component, lentils, are small legumes that come in various colors, including green, brown, and red, each offering unique tastes and textures.
In addition to being delicious, vegan lentil soup is packed with numerous health benefits. Lentils are an excellent source of protein, making them an ideal option for those following a vegan or vegetarian diet. They are also rich in dietary fiber, which aids in digestion and helps maintain a healthy weight by promoting a feeling of fullness. With their low fat content and high nutritional value, lentils contribute to overall health and well-being, supporting heart health, blood sugar regulation, and even reducing the risk of certain chronic diseases.
Why Choose the Instant Pot for Soups?
When it comes to making vegan lentil soup, the Instant Pot is an exceptional kitchen appliance that offers several advantages over traditional cooking methods.
1. Time-Efficient Cooking

3. Energy Efficiency
- Using an Instant Pot consumes less energy than a stovetop or oven, making it an eco-friendly choice. The efficient design means that you can achieve great results while minimizing your energy use.
Choosing the Instant Pot not only saves you time and energy but also elevates the overall flavor of your vegan lentil soup, making it a cooking companion that you’ll want by your side for all your soup-making adventures.

Step-by-Step Recipe for Instant Pot Vegan Lentil Soup
Now that you have all your ingredients, let’s dive into the step-by-step process of making Instant Pot Vegan Lentil Soup.
1. Preparation of Ingredients:
Start by chopping your onion, carrots, and celery into small, even pieces for uniform cooking. Rinse the lentils thoroughly under cold water and set them aside.
2. Sautéing the Vegetables:
Turn on the Instant Pot and select the “Sauté” function. Once hot, add a splash of water or vegetable broth to the pot, then toss in the chopped onions, carrots, and celery. Cook for about 3-5 minutes, stirring occasionally, until the onions become translucent.
3. Adding Lentils and Liquid:
After sautéing the vegetables, add the rinsed lentils to the pot along with the vegetable broth and canned tomatoes. Stir to combine and ensure the lentils are submerged in the liquid.
4. Pressure Cooking:
Secure the lid on the Instant Pot and ensure the steam valve is set to “Sealing.” Select the “Manual” or “Pressure Cook” setting and set the timer for 15 minutes on high pressure.
5. Natural vs. Quick Release:
Once the cooking cycle is complete, let the pressure release naturally for about 10 minutes before carefully switching to quick release to let out any remaining steam. This method helps the lentils finish cooking and develop flavor.
6. Final Seasoning and Adding Greens:
After all the pressure has been released, remove the lid and stir the soup. Taste and adjust seasoning with salt, pepper, and any additional spices. If using spinach or kale, add it to the pot now, letting it wilt into the hot soup.
7. Serving Suggestions:
Serve the soup hot, optionally garnished with fresh herbs or a squeeze of lemon juice for brightness. This soup pairs beautifully with crusty bread or over a bed of rice for a heartier meal. Refrigerate leftovers in an airtight container or freeze for future meals.
