Black Lentils
Black lentils, often sold as beluga lentils because their small round shape and shine resemble caviar, are a variety of Lens culinaris. They hold their shape well after cooking, have an earthy, slightly peppery flavor, and turn a deep matte black rather than mushy when simmered correctly. Unlike red or yellow lentils, they don't need soaking and keep a firm bite, which makes them useful in salads and grain bowls as well as stews.
Varieties
Black lentils (beluga lentils) are a true lentil variety and distinct from urad dal (black gram), which is a different legume commonly used in Indian cooking and has a creamier, starchier interior once cooked. They're also unrelated to black turtle beans, a bean rather than a lentil.
Buying tips
Look for lentils that are uniformly small, dark, and glossy with no dust or debris in the bag. Avoid packages with a lot of broken or split lentils, which cook unevenly and turn mushy faster.
Substitutes
French green lentils (Puy lentils) — 1:1
Closest substitute in texture and cook time; they hold their shape the same way and have a similar peppery, mineral flavor, just green instead of black.
Brown lentils — 1:1
Widely available and cheap, but cook faster and break down more, so start checking for doneness a few minutes earlier.
Black turtle beans — 1:1 by volume, cooked
Different legume with a creamier, starchier texture; works in soups and bowls but won't hold the same firm, distinct grain that black lentils give.
Urad dal (whole, with skin) — 1:1
Also black-skinned but a different pulse entirely, with a creamier interior; fine in dals but changes the texture of a lentil salad noticeably.
Storage
Store dry black lentils in an airtight container in a cool, dark pantry for up to a year. Cooked lentils keep in a sealed container in the refrigerator for about 5 days, or in the freezer for up to 3 months.
How to use
Simmer in salted water or broth for about 20-25 minutes until tender but still holding their shape, then drain. Use in room-temperature salads with vinaigrette, as a bed under roasted vegetables or fish, stirred into grain bowls, or added to soups and stews toward the end of cooking so they don't overcook. No presoaking is needed.
What it pairs with
Pairs well with sherry vinegar, Dijon mustard, roasted beets, goat cheese, cumin, smoked paprika, and roasted or grilled salmon.
Nutrition
Black lentils are a strong plant-based protein and fiber source, providing roughly 18 grams of protein and 15 grams of fiber per cooked cup, along with iron and folate, while staying naturally low in fat.
FAQ
Do black lentils need to be soaked before cooking?
No. Unlike dried beans, black lentils cook fully in 20-25 minutes without soaking, though soaking for an hour can shave a few minutes off the cook time.
Why are they called beluga lentils?
The name comes from their resemblance to beluga caviar: small, round, and glossy black when dry or lightly cooked.
Why did my black lentils turn mushy?
Overcooking or too vigorous a boil breaks down the skins. Simmer gently rather than boil hard, and start checking doneness around the 18-minute mark.
Can black lentils replace black beans in a recipe?
They can in soups or bowls, but black lentils are firmer and smaller, so they won't give the same creamy texture black beans provide in dishes like refried beans.
