Lentils are among the most convenient and nutritious legumes available — unlike dried beans, they require no soaking and cook relatively quickly, making them a weeknight-friendly protein powerhouse. Used in cuisines from South Asia to the Middle East, France, and the Mediterranean, lentils are extraordinarily versatile: they can be cooked into creamy soups and dals, kept firm for salads and grain bowls, sprouted for raw applications, or ground into flour for flatbreads and crepes.
The Lentil Cooking Calculator tells you exactly how much water to use and how long to cook any variety of lentil. Simply enter the dry amount and select the type, and the calculator provides the water needed, the cooked yield, and the stovetop cook time — no soaking step required.
There are five main lentil varieties commonly available: Brown lentils are the most widely available and versatile, holding their shape when cooked and working well in soups and stews. They cook in about 25 minutes. Green lentils have a slightly peppery flavor and hold their shape well; they take about 30 minutes. Red and orange lentils are actually the seeds of brown or green lentils with their hull removed. They cook in just 20 minutes and completely disintegrate into a smooth, creamy puree — ideal for dals, soups, and thick sauces. Black beluga lentils are tiny and hold their shape beautifully when cooked, with an earthy, slightly nutty flavor; they cook in about 25 minutes. French green lentils (Puy lentils) are the firmest variety and have a complex, peppery, mineral flavor; they take about 35 minutes and are prized for salads because they retain their shape and texture.
The water-to-lentil ratio is consistent across all varieties at 3:1, though red lentils can be made thicker or thinner by adjusting water slightly. For cooking, rinse lentils thoroughly in a fine mesh strainer, removing any debris. Place in a saucepan with cold water and bring to a boil. Reduce heat, partially cover, and simmer until tender. Unlike beans, lentils should not be boiled aggressively, as this can cause the skins to burst and the lentils to become mushy prematurely. Do not add salt until the final 5 minutes of cooking.
Nutritionally, lentils are exceptional. They are among the highest protein plant foods, with about 18 grams of protein per cooked cup. They are rich in folate, iron, potassium, phosphorus, and manganese, and provide significant amounts of both soluble and insoluble fiber. Lentils have a very low glycemic index and are particularly beneficial for blood sugar management and cardiovascular health.
All lentil varieties use a 3:1 water-to-lentil ratio and yield approximately 2.5× their dry volume. No soaking is required. Cook times vary by type: red lentils 20 min, brown/black 25 min, green 30 min, French Puy 35 min. Lentils are done when tender throughout but not mushy (except red lentils, which are meant to dissolve).
Water needed = dry lentils × 3
Cooked yield = dry lentils × 2.5
Cook time = 20–35 min (variety-dependent, no soak)
For salads and side dishes, cook until just tender — start checking French and green lentils 5 minutes before the recommended time. For soups, dals, and sauces, cook to your desired consistency; red lentils can cook longer for a smoother texture. Always drain excess liquid from firmer varieties after cooking.

1 cup dry red lentils + 3 cups water, simmered 20 minutes until completely smooth and creamy — the base for a thick, protein-rich dal serving 3–4 people.

1.5 cups French green lentils + 4.5 cups water, simmered 35 minutes until just tender. Drain and toss with vinaigrette, shallots, and fresh herbs for a classic French lentil salad serving 4–6.
No. Unlike dried beans, lentils do not require soaking. Their smaller size and thinner skin allow them to fully hydrate and cook within 20–35 minutes without any pre-soaking. Simply rinse thoroughly before cooking.
Lentils can easily overcook, especially red lentils, which are meant to dissolve but can turn too watery if cooked too long. Brown and green lentils become mushy if boiled too vigorously or cooked past their time. Simmer gently and start checking for doneness 5 minutes before the recommended time.
Yes. Substituting vegetable or chicken broth adds significant flavor depth, especially for soups and pilafs. Use the same 3:1 ratio. Note that broth adds salt, so taste before adding additional seasoning.
Adding salt early in cooking can toughen the lentil skins, similar to the effect on beans. Add salt in the final 5 minutes of cooking for tender lentils with seasoning fully absorbed.
Cooked lentils keep in the refrigerator for up to 5 days in an airtight container. They freeze well for up to 3 months. Reheat with a splash of water on the stovetop or in the microwave. Cooked lentils also work well cold in salads straight from the refrigerator.
Red lentils (actually orange when raw) are hulled lentils that cook in just 20 minutes and dissolve into a creamy paste — ideal for soups, dals, and sauces. Green lentils retain their shape and have a firmer, more distinct bite — better for salads, side dishes, and grain bowls.
Yes. Cook green or brown lentils on high pressure for 6–8 minutes with a natural pressure release. Red lentils cook for just 3 minutes on high pressure. Use the same 3:1 water ratio. Be careful not to overfill the pot, as lentils expand and can foam.
As a side dish or in a salad, plan for 0.25–0.33 cups of dry lentils per person (0.625–0.825 cups cooked). As a main protein source in a dal or soup, use 0.33–0.5 cups dry per person.
Lentils are not a complete protein on their own — they are low in the amino acid methionine. However, pairing lentils with grains like rice, bread, or quinoa creates a complementary amino acid profile equivalent to complete animal protein. Traditional Indian dal-rice and Middle Eastern mujaddara are examples of this complementary protein pairing.
Red lentils are ideal for thick, creamy soups because they dissolve completely. Brown and green lentils work well for heartier soups where you want distinct lentil pieces. French lentils and black beluga lentils are best saved for salads and dishes where you want the lentils to hold their shape.
