How to make Lentil Soup in Pressure Cooker
Sauté the vegetables.
Press the “Sauté” button and add a tablespoon of olive oil. Add chopped onions and sauté them for about 5-7 minutes or until they are soft and translucent. (Photos 1-3)
Add minced garlic and stir for about 30 seconds. Then add the carrots and stir again. Now we can turn off the “Sauté” function. (Photos 4-6)
Add the rest of the Ingredients.
Add rinsed lentils, crushed tomatoes, vegetable broth, water, dried oregano, and dried thyme and give it a stir. (Photos 7-12)
Close the lid and make sure that the venting knob is set to “Seal”.
Cook on manual high pressure for 10 minutes. When done, you can naturally release the pressure for about 10 minutes, then do a quick release.
Open the lid and stir. You can add some salt if needed.
How to make Lentil Soup on the stove
If you don’t have a Pressure Cooker, you can also make this delicious soup on a stove top. It will take a bit more time, but the results will be the same.
For this recipe, I prefer to use a pot with a thick bottom (like a 6 Qt Dutch Oven), because we need to sauté the vegetables.
Preheat the pot with olive oil over medium/high heat, then add the chopped onions. Sauté for about 5-7 minutes, then add minced garlic and cook for about 30 seconds, until it releases the aroma.
Add the carrots, and cook for couple of more minutes.
Add rinsed lentils, crushed tomatoes, vegetable broth, water, dried oregano, and dried thyme and give it a stir.
Bring it to boil, then reduce the heat to low. Put the lid on and simmer for about 35-40 minutes, occasionally stirring.
What else can I add to this soup?
This recipe is good on its own, but if you have any vegetables that need to be used, you can easily add them to this meal. Here are a few ideas:
- Sweet potatoes or regular potatoes. Just chop them in ½-inch cubes and add together with the lentils.
- Parsnips. Also chop it in 1/2-inch cubes.
- Diced tomatoes (used in place of the crushed tomatoes).
- Spinach. You can add it after the soup is cooked. Press the “Sauté” button, add spinach, and cook for a few minutes until it’s wilted.
Frequently Asked Questions
I prefer to use green lentils, but you also can use brown, red or yellow variety. But don’t use French lentils because they keep their shape and fail to make the soup creamy.
After it’s cooled off, transfer to an air-tight container. It will stay fresh in the fridge for up to 5 days.
This soup freezes really well. Keep it in an air-tight container or a zip-locked bag and freeze for up to 3 months. To thaw, put it in the fridge overnight, then reheat.
