It’s SO cold now and by cold, I mean it’s a wimpy 45 degrees here in the San Francisco Bay Area! I know, I know… 45 degrees isn’t that cold compared to other parts of the US.

Anyway, I warm up with soups. And this Instant Pot lentil soup is so hearty, comforting that I almost forget how cold it is. Just kidding! I have the heater on full blast!

Lentil soup is so filling and nourishing, especially for winter. I can’t believe how hearty it is without meat! It’s a nice change when you want a break from eating meat.

This recipe isn’t vegetarian though because I use chicken base. But feel free to use vegetable stock instead.

Lentil soup reminds me of being in San Diego, at my friend’s house, where I first tried lentil soup.

I honestly never made lentil soup because I thought it was too hard to cook dry lentils. And I would buy cooked lentils instead… that is until I tried cooking it in the Instant Pot!

Wow, it’s SO easy to make now because I don’t have to nurse anything over the stove. Yay!

What is Mirepoix?

Mirepoix is used as a base for this lentil soup. And boy, does it make the flavor bloom!

What is mirepoix? It’s a mix of diced onion, celery, and carrots. It’s in a 2:1:1 ratio.

You saute it in oil, to sweat out the vegetables. This crucial step adds so much flavor into soups! It works in corn chowder and chicken soup too!

In my video, I show my shortcuts to save time and also the process of how to sort lentils and why it’s important to do so.
