Instant Pot lentils are an easy way to add plant-based protein to any meal, and most varieties cook in just 9 minutes or less. Below you’ll learn how to cook red, green, brown, and black lentils in your pressure cooker for perfect results every time.

How to Cook Lentils in the Instant Pot

To cook lentils in the Instant Pot, you’ll simply combine dry lentils and water. Then all you have to do is secure the lid, move the steam release valve to the “sealing” position (don’t forget this, or your pot won’t seal!), and press a button.

What I love about using an electric pressure cooker, is that you don’t have to wait for a pot of water to come to a boil first, and you don’t have to keep an eye on the pot as the lentils cook to perfection. The cooking process is completely hands-off!

How Long to Cook Lentils

Most lentils cook in just 9 minutes, with a quick release. Keep in mind that it can take up to 10 minutes for the pot to come to pressure, so be sure to factor in that extra time when planning your meals.

Here’s how long different varieties need to cook:

  • Green lentils: 9 minutes (10 if you want them softer)
  • Brown Lentils: 9 minutes (10 for softer)
  • Black Lentils: 9 minutes
  • Red Lentils: 5 minutes or more (they are mushy regardless)

In each case above, I use a quick release when the cooking time is completed. That means I move the steam release valve to venting to release the pressure as soon as the screen reads LO:OO on my Instant Pot. If you don’t hear the pressure cooker beep when it’s done, it’s okay if you don’t release the pressure right away; the lentils will just be a little softer when you get around to them.

To see a demonstration of the quick release be sure to check out my How To Use Your Instant Pot tutorial, where I show you the 10 things you need to know about your Instant Pot in a quick 3-minute video.

Do Lentils Need to Be Soaked?

Lentils are quick-cooking and do not need to be soaked before you get started. They cook just as fast as my Instant Pot Black Beans, and are even faster than Instant Pot Chickpeas, but since no soaking is required, they are a quick & convenient source of plant-based protein.

How to Serve Lentils

The recipe below will teach you how to cook lentils on their own, so you can use them in a number of different ways as part of your meal prep routine.

Below you’ll find some easy ways to serve the pre-cooked lentils.

  • Toss them with BBQ sauce for a vegetarian sandwich
  • Serve them over a salad for plant-based protein
  • Make this easy Lentil Salad
  • Stir them into a jar of marinara sauce for vegetarian spaghetti
  • Use them to make Vegan Meatloaf

To cook the lentils as part of a complete recipe, here are some easy recipe ideas to help you get started.

I hope this tutorial will help you get more comfortable with using your Instant Pot, and will make you more confident in converting any recipe for your electric pressure cooker, too.

How to Convert a Recipe for the Instant Pot

When I want to make a recipe in my Instant Pot, and don’t have directions for it already, I usually look at the ingredient that will cook the longest, and use that cooking time as a starting point.

For example, if I want to make Lentil Bolognese in my Instant Pot, the green lentils will determine the cook time. In that case, I’d cook the lentil-based sauce for 10 minutes under high pressure, so that the lentils are tender. (I always err on the longer side of cooking lentils if they are cooking in a tomato sauce, as the acid in the tomatoes may slow down their cooking process.)

Can You Cook Lentils with Salt?

When cooking lentils in a recipe, I prefer to omit the salt until the lentils are 100% tender, as salt can sometimes interfere with the lentils softening. This is definitely the case when you cook lentils with soy sauce, so don’t add soy sauce to a recipe until after the lentils are tender.

In my experience, this happens more often with pressure cooking than with stove top cooking, and it usually happens more often when an acidic ingredient is in the recipe, too, like tomatoes or lemon juice. So, keep that in mind when cooking with lentils, and add the salt at the end if you want to stay on the safe side.

How to Season Lentils

The recipe below will guide you on cooking plain lentils that you can use in any meal or recipe, but if you want to season them at the same time, here’s my favorite combination for a taco-inspired flavor.

Per cup of dry lentils:

  • 1 teaspoon cumin
  • 1 teaspoon chili powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon salt

When the lentils are done cooking, add a squeeze of fresh lime or lemon juice, and adjust the seasoning as needed to your taste. If you use this seasoning with red lentils, their mushy texture reminds me of refried beans! You can use the Instant Pot’s sauté function if you want to cook some chopped onion and garlic first, then you can add in the lentils and water and cook them together using the timing below.

Here's how to cook lentils in the Instant Pot, including green, brown, black, and red lentils. You can use these as part of your meal prep for the week!
prep5 mins cook9 mins Pressurization:10 mins total24 mins
Servings:4

Ingredients
 
 

  • 1 cup green, black, or brown lentils (see notes for red lentils)
  • 1.5 cups water
  • 1/4 to 1/2 teaspoon salt (optional)

Instructions

  • Combine the lentils and water in the bottom of the Instant Pot. You can add up to 1/2 teaspoon of salt if you want them seasoned, but keep in mind that they may turn out a little more firm that way. Don't season with salt until the end of the cooking cycle if you want to guarantee soft lentils.
  • Secure the lid and move the steam release valve to Sealing. Press the Manual or Pressure Cook button to cook at high pressure for 9 minutes. (They will still have a little bite to them this way; cook for 10 minutes for softer lentils.) It will take 10 minutes for the pot to come to pressure before the cooking cycle begins, so the screen will just read "On" until then.
  • When the cooking cycle completes, immediately move the steam release valve to Venting to release the pressure right away. Make sure your hand isn't over the steam release valve, to avoid the hot steam touching your skin. When the floating valve in the lid drops, the pressure is released and it's safe to open the lid. (If you forget to release the pressure right away, it will still be okay-- your lentils will just be softer when you remember to go check on them.)
  • Stir the lentils and make sure they are tender to your liking. You can always add an extra 1/2 cup of water and pressure cook them again for 2-3 minutes, if you want them softer, but they should be done at this point. There shouldn't be too much liquid left in the pot, so you can use them right away without draining them.
  • Use a slotted spoon to scoop them out, then serve warm. For serving ideas, be sure to check out the post above! You can store cooked lentils in an airtight container in the fridge for up to 1 week.

Notes

Red lentils cook in just 5 minutes at high pressure with a quick release. Keep in mind that red lentils will have a mushy texture no matter what, so you can cook them longer if making a soup or curry with them. They will completely dissolve into a soup and will act as a thickener if you cook them for 10 minutes at high pressure, like in my Curry Chicken Soup recipe.

  1. Does the water to lentil ratio change if I cook more at a time? I want to cook dry lentils in 1lb bag batches. Thanks!

    1. You probably won’t need to double the water when you add more lentils, but I would definitely make sure they are covered for even cooking and don’t go past the “max fill line” for liquids in your Instant Pot for safety.

  2. Just made this and it came out great! Thank you! I did change it up a bit. I doubled the recipe and used 2 cups of Maggi chicken bouillon and 1 cup of water instead of the salt option.

  3. One more handy recipe! If it’s simple, WFPB, and easy… it’s Detoxinista! Thanks for all the recipes, hints, tips, and encouragement!

    1. I’m so sorry to hear that! I’d be happy to help you troubleshoot. Which variety of lentil did you try, and did you add any seasonings? I would double-check to make sure the sealing ring that’s in the lid for your pot is properly placed, as it sounds like their might be a sealing issue. Lentils should definitely NOT be raw after 10 minutes of pressure cooking. Also be sure that the steam release valve is moved to the “sealing” position, so that steam doesn’t escape. That could definitely cause under-cooking, as well.

      1. Brown lentils. No seasonings. Just water and lentils. It wasn’t raw, but it was inedible. Doubt it was a sealing issue. I use the instant pot daily for rice, so I’m pretty familiar with it. The recipe requires at least 3 more minutes of pressure cooking. Also if you follow this advice: “You can always add an extra 1/2 cup of water and pressure cook them again for 2-3 minutes” Then the lentils just burn to the bottom.

        1. Well, darn! Sorry I couldn’t be more help! I’ve been cooking lentils like this for the past 3 years and haven’t had any issues, but the Instant Pot does sadly vary a LOT by machine (mine is older) and lentils can also cook differently based on their age, your altitude, the humidity, and all sort of other factors. Hope you’re able to figure out what works best for your home!

    2. Sounds like your lentils may have been sitting on a shelf too long. Older legumes won’t absorb water well and need either longer cooking, or are sometimes just unsalvageable. I had some older beans I pressure cooked for hours and they were still inedible!

  4. Using the two pans in the pot-in-pot method, made plain lentils (one pan) and asparagus (the other pan) — set the Crockpot multicooker for 25 minutes, walked the dog, came back, fired up a frying pan, sauteed a chopped onion and added some BBQ sauce and placed most of the lentils in the pan (the remainder was for the dog). Toasted some buns and assembled lentil BBQ sandwiches with a side of asparagus. Real easy! Thanks for the idea!

    1. Ooh, thanks for sharing about the pot-in-pot method! I hadn’t tried that with lentils yet. Sounds amazing!!

  5. Made last night…finally a recipe with the right times for pressure cooking lentils in an electric pressure cooker. Lentils were perfectly done just the way I like them, 9 mins, with the right ratio of water to lentils and timing. Thank you!

  6. I don’t have an Insta Pot as they are very expensive where I live. Do you have times for cooking them in a boiler with a lid? Thank you

  7. So easy to make and so tasty! Megan Gilmore’s recipes to cook using the instantpot are the easiest.
