Wondering how to make lentils without a recipe? All you need is that lentil to water ratio, which works every time. This ratio is for brown and green lentils only (since red and yellow lentils cook differently — they become mushier when cooked and are used for stews). Here is is:

Lentil to water ratio (brown & green): 
1 part lentils to 3 parts water

That means if you’re planning to cook 1 cup of lentils, you’ll combine it with 3 cups of water in a pot. Simple as that! Here are a few other things to keep in mind:

  • Do you have to boil the water first? No! Place the lentils and water in a pot together and bring to a high simmer, then simmer.
  • How long do you cook brown and green lentils? 20 to 25 minutes, until the lentils are tender but still hold their shape. You can drain any excess liquid.
  • Can I make lentils with broth instead of water? Yes! Cooking with broth brings in extra flavor.

Lentil serving sizes

But how much lentil to cook? It’s all in the math. Here are a few handy formulas to remember:

  • How much does 1 cup of dry lentils make? 1 cup dry lentils = about 2 ½ cups cooked lentils. Lentils increase in volume about 2 ½ times when cooked.
  • How much is 1 serving of lentils? Plan for about 1 to 1 ½ cups of cooked lentils per serving.
  • How much dry lentils do I need for about 4 cups cooked? Since lentils increase 2 ½ times when cooked, divide the cooked volume by 2 1/2. 1 ½ cups dry lentils = About 4 cups cooked lentils

Got a pressure cooker or Instant Pot?

You can make lentils in an Instant Pot too! That’s got a different lentil to water ratio; here’s our recipe! Instant Pot Lentils

    Can we use water that the lentils cooked in for soup?

    1. Alex Overhiser says:

      It tends to be pretty bland and gritty.

    Thank you so much for all the information and for this wonderful website beyond this page.
    One question: for French or black lentils, will it be the same water to dry lentils ratio as it is for the brown and green lentils?
    Thanks in advance!

    I really like the recipe, but quite confused on what you refer to a “simmer” is this covered? Uncovered? I am new to cooking. Thanks.






    1. Alex Overhiser says:

      Simmer uncovered.

    Thanks for this. I appreciate the updates and improvements from reader comments. It would be helpful to have accurate, weight-based measurements too, in grams and millilitres, rather than volume measurements like cups. It’s far easier and quicker (and more accurate) to measure ingredients on a kitchen scale than getting out cups and scooping.
