Instant Pot Lentil Soup with Squash
This Instant Pot lentil soup with squash is quite possibly the coziest and flavorful soups for this season.
It is chock full of veggies and I didn’t intend on doing this (because I don’t create recipes specifically for dietary restrictions even though I try to be cognizant of it), it is allergen-free, vegan, and vegetarian friendly!
I had a bunch of vegetables leftover from a Friendsgiving I hosted a couple weeks ago and instead of letting them go bad, they went into this Instant Pot lentil soup!
It is the perfect way to repurpose leftover ingredients and you get a deliciously flavorful, comforting soup out of it.
Trust me, once the temperature dips even more, you’ll be glad you have this Instant Pot lentil soup in your arsenal.
ALSO! Who doesn’t love quick meals thanks to your Instant Pot/pressure cooker?
This Instant Pot lentil soup comes together in less than 30 minutes. It takes only 8 minutes to cook but you gotta wait a bit for it to come to pressure, but even then, most of the time cooking lentils takes way longer than 30 minutes!
What is an Instant Pot?
An Instant Pot is basically a glorified pressure cooker.
You technically don’t need an Instant Pot if you have one of those old school stovetop pressure cookers but the technology on the Instant Pots are pretty nice and they’re multifunction.
Can I make this Instant Pot lentil soup in the slow cooker?
I personally haven’t tried it that way but you can make this in the slow cooker probably for 4-6 hours on low and 2-3 hours high.
Can I make this on the stovetop?
Yes. It might take maybe 45 minutes, I’m guessing?
To be honest, I’ve only made lentils in the Instant Pot so my timing may be a bit off for stovetop.
Can I use a different bean?
You can, but it’ll likely take longer to cook if they’re dried larger beans.
Can I use canned lentils or canned beans?
What other vegetables can I add to this?
Other root vegetables would be great in this, but if you are adding more delicate vegetables, keep them at bigger chunks and/or add once the soup is done and use the residual heat to cook it.
Can I add some meat to the soup?

Really not sure what I did incorrectly (I followed the instructions for 4 servings; IP) and got the food burn error numerous times. Thought I didn’t mix it well, so I deglazed and tried again. Got another food burn error, so I took half out thinking that the veggies were too heavy for the lentils. Deglazed and tried once again, and still got the food burn error. So sad; Uber eats time.. 😿

@Victor, Sometimes I find that tomatoes cause a burn error so whenever a recipe calls for any type of tomatoes or tomato sauce, I normally mix all the other ingredients together, and then place the tomatoes on the top of the mixture (without mixing). It doesn't hinder the cooking in any way.

hey Victor, sorry to hear your troubles with this. so you aren't to mix the tomatoes in...just plop it on top b/c for some reason, tomatoes give instant pot burn errors.

Was delicious! We substituted crushed tomatoes for the fire roasted tomato. Added fresh herbs and use spinach instead of kale. Perfect meal for a cold night!

YAS YAS YAS!! Made this tonight and it was amazing! I don’t have an instapot so I made it on my stove. It DID take 40 min. The only differences I had done were: sautéed the onions, added 3 cloves of diced garlic, and 8 cups of vegetable broth. Beautiful flavor and clean eating! I put minimal salt and pepper. WONDERFUL recipe and highly recommend. So amazing with crusty bread

The recipe did not specify what type of lentils to use so I used a soup mix of different lentils. I followed everything to the letter except that I added Kosher salt rather than salt at the end. When I completed the process, I felt that there was not enough liquid and the lentils had become more of a dahl. I added two cups of stock. The soup was wonderful. I would add that I just got the smart cooker and yours was my initial outing. Many thanks!
