How to Cook Red Lentils: Times, Ratios and Easy Tips

If you want to know how to cook red lentils well, the secret is simple. Decide on the texture before the pot goes on the stove. Red lentils cook fast, so they can be soft and creamy or tender and separate. It all depends on the water and the heat.

This is my weeknight method. It needs one pot, no soaking, and about fifteen minutes.

Why red lentils cook so quickly

Red lentils are sold hulled and split. With the seed coat gone, water gets in quickly. That is why they soften in a fraction of the time whole lentils need.

According to the Harvard T.H. Chan School of Public Health, split lentils take about 10 to 15 minutes. Whole lentils need closer to 20 to 30. The same page also notes that soaking is not necessary. Lentils are a source of protein, fiber, folate, iron and potassium, which is why they earn a spot in my pantry.

Our Red Split Lentils (Masoor Dal) are exactly this kind. They are small, coral-coloured and ready to cook straight from the bag.

Before you start: rinse and check

Tip the lentils into a bowl and look them over. Pick out any tiny stones or discoloured pieces. Then rinse them in a sieve under cold water.

Keep rinsing until the water runs mostly clear. At first it looks cloudy, because of the starch on the surface. Rinsing off that starch means less foam in the pot and a cleaner texture.

How to cook red lentils on the stove

Here is the basic method. After that, I explain how to steer it toward the texture you want.

1. Add 1 cup of rinsed red lentils to a saucepan.
2. Pour in the water. Use 2 cups for tender lentils, or 3 cups for a soft, soupy pot.
3. Bring it to a boil, then skim off any foam.
4. Lower the heat until the surface barely bubbles.
5. Simmer uncovered and start tasting at about 8 minutes.
6. Stir in salt once the lentils are soft.

Most batches are done in 10 to 15 minutes. However, stoves differ, so trust the tasting spoon more than the clock.

For bowls and salads: tender, still whole

Use the smaller amount of water and keep the heat very low. A hard boil tumbles the lentils against each other and breaks them apart.

Check them early. As soon as they are tender with a little bite, drain them. Then spread them on a plate to cool. Red lentils keep cooking in their own heat, so leaving them in the hot pot turns them to mush.

Even with care, they will be softer than brown lentils. That is simply their nature. If you want lentils that truly hold their shape, see my guide on how to cook brown lentils.

For dal and soup: soft and creamy

This is where red lentils shine. Use the larger amount of water and let them simmer until they collapse. Afterwards, whisk the pot for a few seconds, and it turns silky with no blender at all.

For a classic finish, spoon a hot tadka of ghee, cumin and garlic over the top. Our masoor dal tadka recipe walks through it step by step.

When to add salt, lemon and tomato

I add salt at the end, once the lentils are soft. That way I can taste and adjust properly.

Acidic ingredients, such as lemon juice, vinegar or tomato, work best near the end too. In my kitchen, lentils cooked with a lot of acid from the start soften more slowly. So I simmer them in plain water or stock first. Then I stir in the lemon or tomato once they are tender.

Red lentils for weeknight meal prep

Red lentils are my favourite batch-cooking shortcut. A single pot on Sunday gives me a head start on several meals.

• Soups: stir a cup of cooked lentils into vegetable soup to thicken it and add protein.
• Pasta sauce: mix soft red lentils into tomato sauce for a heartier, plant-based sauce.
• Grain bowls: pair tender lentils with roasted vegetables, greens and a lemony dressing.
• Quick dal: reheat creamy lentils with a fresh tadka for a ten-minute dinner.

Let the lentils cool, then store them in a covered container in the fridge. Use them within a few days. For longer storage, freeze them flat in labelled bags. They thaw quickly and reheat well with a splash of water.

Common mistakes to avoid

Most problems come from heat and timing, not the lentils themselves.

• Boiling too hard. A rolling boil breaks the lentils and makes the pot foam over.
• Walking away. Red lentils can go from tender to porridge in a few minutes.
• Skipping the rinse. Unrinsed lentils foam more and can taste dusty.
• Using old lentils. Very old lentils may cook unevenly, so buy what you will use.

FAQ: cooking red lentils

Do red lentils need to be soaked?

No. Red lentils are split and hulled, so they cook quickly without soaking. A good rinse is all they need.

Why did my red lentils turn to mush?

Usually the heat was too high, or they cooked a little too long. Use less water, keep the simmer gentle, and drain them the moment they are tender.

What is the ratio of water to red lentils?

I use 2 cups of water per cup of lentils for tender lentils. For soup or dal, I use about 3 cups, and add more if the pot gets too thick.
