Cooking lentils in the instant pot means no soaking required, just a quick rinse and twenty minutes under pressure. If you have ever wondered how to cook lentils instant pot style, you are in the right place. This method saves time, energy, and delivers perfectly tender lentils every single time.
Lentils are a powerhouse of protein, fiber, and minerals. They are cheap, versatile, and store well. But cooking them on the stovetop can be tricky—they might turn mushy or stay too firm. The Instant Pot takes the guesswork out.
In this guide, you will learn the exact steps, water ratios, and timing for different lentil varieties. No more burnt pots or undercooked bites. Let’s get started.
Why Use An Instant Pot For Lentils
The Instant Pot is a pressure cooker, slow cooker, rice cooker, and more. For lentils, pressure cooking is the star feature. It cuts cooking time by half compared to stovetop methods.
You do not need to soak lentils overnight. Just rinse them, add water, and set the timer. The high pressure breaks down the lentils’ cell walls quickly, resulting in a creamy texture without constant stirring.
Another benefit is energy efficiency. The Instant Pot uses less electricity than a stovetop burner. Plus, it seals in flavors, so your lentils taste richer.
How To Cook Lentils Instant Pot
This is the core section. Follow these steps for foolproof lentils every time. The process is the same for most varieties, but cooking times vary slightly.
Step 1: Rinse And Sort Your Lentils
Start by measuring the amount of lentils you need. One cup of dry lentils yields about 2.5 to 3 cups cooked. Place them in a fine-mesh strainer and rinse under cold water.
Pick through the lentils quickly to remove any small stones or debris. This is rare but worth doing. No need to soak—just rinse until the water runs clear.
Step 2: Add Lentils And Liquid To The Pot
Transfer the rinsed lentils to the Instant Pot insert. Add water or broth. The general ratio is 3 cups of liquid for every 1 cup of dry lentils. This works for brown, green, and French lentils.
For red and yellow lentils, use 2.5 cups of liquid per cup of lentils. They break down more and absorb less water. You can also add a pinch of salt, but wait until after cooking to add more—salt can toughen the skins.
Step 3: Set The Cooking Time
Close the lid and set the valve to “Sealing.” Select the “Manual” or “Pressure Cook” setting. Adjust the time based on the lentil type:
- Brown lentils: 16–18 minutes
- Green lentils: 18–20 minutes
- French lentils (Puy): 20–22 minutes
- Red lentils: 8–10 minutes
- Yellow lentils: 10–12 minutes
If you like firmer lentils, use the shorter time. For softer, creamier lentils, use the longer end. Natural release is best for most lentils—let the pressure come down on its own for 10–15 minutes, then quick release any remaining steam.
Step 4: Release Pressure And Check
After the timer beeps, let the pot sit for 10 minutes (natural release). Then carefully turn the valve to “Venting” to release any leftover steam. Open the lid away from your face.
Stir the lentils. They should be tender but not mushy. If they are still too firm, add a little more liquid and cook for 2–3 more minutes under pressure. Drain any excess liquid if needed.
Step 5: Season And Serve
Now is the time to add salt, pepper, herbs, or spices. Stir in a tablespoon of olive oil or butter for richness. Lentils pair well with garlic, cumin, thyme, or bay leaves.
Use them in salads, soups, stews, or as a side dish. They store well in the fridge for up to 5 days or in the freezer for 3 months.
Lentil Varieties And Their Best Uses
Not all lentils cook the same. Knowing the differences helps you choose the right one for your recipe. Here is a quick breakdown.
Brown Lentils
These are the most common. They hold their shape well but become creamy when cooked longer. Perfect for soups, stews, and side dishes. Cooking time: 16–18 minutes in Instant Pot.
Green Lentils
Green lentils are slightly peppery and firm. They stay intact even after pressure cooking. Great for salads and cold dishes. Cooking time: 18–20 minutes.
French Lentils (Puy)
These are small, dark green, and have a nutty flavor. They keep their shape beautifully. Ideal for warm salads and side dishes. Cooking time: 20–22 minutes.
Red Lentils
Red lentils are split and cook very quickly. They turn soft and almost mushy, making them perfect for dals, purees, and thickening soups. Cooking time: 8–10 minutes.
Yellow Lentils
Similar to red lentils but slightly milder. They also break down easily. Use them in Indian dishes or creamy soups. Cooking time: 10–12 minutes.
Tips For Perfect Instant Pot Lentils
These small adjustments can make a big difference in texture and flavor.
- Do not overfill the pot. Lentils expand, so keep the total volume below the max fill line.
- Use broth instead of water for more flavor. Vegetable or chicken broth works well.
- Add aromatics like garlic cloves, onion halves, or a bay leaf before cooking.
- Acidic ingredients like tomatoes or vinegar should be added after cooking. Acid can prevent lentils from softening.
- Natural release is key for firmer lentils. Quick release can cause them to burst.
- Rinse thoroughly to remove dust and reduce gas-causing compounds.
Common Mistakes To Avoid
Even with an Instant Pot, a few errors can ruin your lentils. Here is what to watch for.
Using Too Much Liquid
Lentils absorb a lot of water, but too much can make them soupy. Stick to the ratios above. You can always add more liquid after cooking if needed.
Not Releasing Pressure Properly
If you quick release all the steam immediately, lentils can splatter and become mushy. Let them rest for 10 minutes first.
Adding Salt Too Early
Salt can toughen lentil skins, especially for brown and green varieties. Add salt at the end of cooking for best texture.
Overcooking Red Lentils
Red lentils cook fast. Even 2 extra minutes can turn them into paste. Set a timer and use quick release if you want them slightly firmer.
How To Store And Reheat Cooked Lentils
Cooked lentils are meal prep gold. Here is how to keep them fresh.
Let the lentils cool completely before storing. Transfer them to an airtight container. They will keep in the refrigerator for 4–5 days.
For longer storage, freeze them in portion-sized bags or containers. They last up to 3 months. Thaw overnight in the fridge or reheat directly from frozen in the microwave or on the stovetop.
To reheat, add a splash of water or broth to restore moisture. Microwave for 1–2 minutes or simmer on the stove for 5 minutes.
