Lentils are one of the world’s ancient culinary miracles: they deliver 18g of clean plant-based protein and 15g of dietary fiber per cooked cup, cost pennies, and unlike dried beans, require zero pre-soaking. In this definitive guide on how to cook lentils, we share the essential timing differences between brown, green, and red lentils so your dishes never turn into an unappetizing sludge.
How to Cook Lentils (Brown, Green & Red Lentils Master Guide)
Ingredients
Method
- Sort and rinse: Spread 1 cup dry lentils on a plate or cutting board to quickly pick out any stray pebbles or broken kernels. Rinse in a fine-mesh strainer under cold water.
- Combine with liquid & aromatics: Place lentils, 3 cups water (or broth), smashed garlic cloves, and bay leaf into a medium saucepan. Bring to a rapid boil over medium-high heat.
- Simmer gently: As soon as boiling begins, reduce heat to low so liquid maintains a gentle, lazy simmer. Cover loosely with a tilted lid. Cook: 20 to 25 minutes for brown lentils; 25 to 30 minutes for green/Puy lentils; or 15 minutes for quick red lentils.
- Season with salt: Stir in ½ teaspoon sea salt during the last 5 minutes of cooking. (Adding salt at the beginning can make the outer skins tough).
- Drain excess liquid & finish: Test a lentil with your teeth—it should be tender with a pleasant bite, not crunchy or mushy. Drain any excess water in a colander, discard the bay leaf, drizzle with olive oil, and serve.

Frequently Asked Questions about Cooking Lentils
Do lentils need to be soaked before cooking?
No! Unlike kidney beans, chickpeas, or black beans, lentils are small and tender enough to cook in 20 to 25 minutes directly from dry without any pre-soaking.
Why are my lentils tough and not softening?
Two factors cause tough lentils: adding acidic ingredients (tomatoes, lemon, vinegar) or excessive salt at the very beginning of cooking. Acid and salt strengthen the hemicellulose in the lentil skins, preventing water absorption. Always add acid and salt during the last 5 minutes!
What is the ratio of water to lentils?
Use 3 cups of liquid per 1 cup of dry lentils. This gives them ample room to hydrate and expand without boiling dry. Any excess liquid is easily drained off at the end.
Can cooked lentils be frozen?
Yes! Brown and green lentils freeze brilliantly for up to 3 months. Drain thoroughly, cool completely, and freeze in flat zip-top bags. Thaw directly into hot soups, chilis, or salads.
