Lentil to water ratio

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?

      1. Near the top of the page it says:
        “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 cover and simmer.”

        So we do or do not cover while cooking?

  1. I just discovered lentils. Thank you for NOT having 14 pages of your life to get to the facts. I got everything I needed to understand how to make my Gypsy lentil dish a winner. Lentils go so well with smoked sausage. Did not want a stew or soup. While writing this I looked looked over your site and you guys are now bookmarked. Thank you.

  2. Hi there, I really don’t like draining lentils if I don’t have to.

    I really just want to cook brown/green lentils on the stove for
    a reasonable amount of time (say 10-20 min) until all the water is soaked up.

    My main aim would be to create a moist (but not too moist) neutral filling to mostly use for taco/burrito filling and season as appropriate. I don’t want something like that to take forever at the end of a workday.

    What do you think? 2 or maybe 2.5 cups of water per cup of green lentils?

    1. We would follow the recipe! It takes only 20 to 25 minutes to get tender lentils. Use 1 1/2 cups brown or green lentils and 4 1/2 cups water or vegetable broth. Then drain any excess liquid. Good luck!
