Ingredients Used in Instant Pot Lemon Red Lentil Soup

instant pot lemon red lentil soup ingredients
  • Red Lentils — red lentils are readily available, inexpensive and quickly cook into a creamy texture that makes for an extremely satisfying vegan soup.
  • Onion — diced, if you don’t like the texture of diced onion, you can grate the onion. Or you can puree the soup with an immersion blender after cooking.
  • Carrot — grated, you can include carrots in this soup or leave them out. We prefer this soup with carrots but you will love it either way.
  • Vegetable Stock — best if you use organic vegetable stock. You can use homemade vegetable broth or a carton for convenience.
  • Garlic — cloves, minced
  • Lemon Juice — freshly squeezed
  • Cumin — ground
  • Hot Sauce — Optional, we use Frank’s Red Hot for convenience, 4-5 shakes, or you can add 1/2 teaspoon of cayenne pepper.
  • Salt — Himalayan, ground, enhances the flavor of the soup.

Health Benefits of Lemon Red Lentil Soup

Red lentils are packed with protein, fiber and iron. They are low in calories but provide a creamy texture that satisfies, as a great alternative to cream based soups. The soup is vegan and gluten free.

Kitchen Tools Needed for Lemon Red Lentil Soup

We use a 6 quart Instant Pot to make this soup. A lemon juicer and garlic press are helpful but not necessary. A colander to rinse and drain your lentils, after rinsing I set my colander aside with a plate underneath to catch any water that drips.

How to Cook Instant Pot Lemon Red Lentil Soup

STEP 1 — Gather and Prepare your Ingredients

You will need to gather your ingredients and spices and prepare your vegetables and lentils. Lentils should be washed well and drained, rinse them in a colander until the water runs clear. Wash (scrub well) and trim ends from carrot, then grate it. Dice your onions and grate or put your garlic cloves through a garlic press. Wash a lemon, cut it in half and squeeze the juice from it.

STEP 2 — Fill Your Instant Pot

Combine the ingredients in your Instant Pot. First add the rinsed red lentils, then vegetable stock, and all of the remaining ingredients EXCEPT lemon juice.

STEP 3 — Cycle Your Instant Pot and Add Lemon Juice

Fasten the Instant Pot lid securely. Set the valve to SEALING and set to HIGH pressure for 15 minutes. Once complete, you can quick release the pressure. If you forget and it natural releases the pressure, that’s ok. When the pressure pin drops, it is safe to open the lid. Add the lemon juice and stir.

You can choose to give it a quick blend with an immersion blender, or keep it as is for its lovely texture. Transfer to individual bowls and allow to cool sufficiently. Serve as is or enjoy with any combination of salads, rice, eggplant chickpea stew, grilled vegetables or meat, pita bread and dips.

Lemon red lentil soup can be kept in an air tight container in the refrigerator for up to five days. Because it lasts a few days it can easily be prepped and made ahead.
