This recipe was tested in a 6-quart Instant Pot.
How Much Water Do I Add for More Lentils?
For the stovetop, used a 3:1 ratio of water to lentils (3 cups water for every 1 cup black lentils). For the Instant Pot, use 1 ¾ cups water for every 1 cup black lentils.
Cooking Instant Pot lentils for 6 minutes + natural release will yield a firmer lentil with a less creamy interior. If you're using black lentils for a cold salad and like a firmer texture, then try 6 minutes.
Cooking Instant Pot lentils for 10 minutes + natural release will yield a soft, creamy lentil and the shape will start to break down.
If you're simmering on the stovetop for more than 20 minutes, keep an eye on the lentils to make sure all of the water doesn't boil away before the lentils are done. If needed, add a little bit more water until the lentils reach the texture you want.
Lentils keep well in the refrigerator for up to 5 days, making it a perfect meal prep ingredient.
