Using the pressure cooker function reduces cooking time significantly, turning tiny legumes into a creamy, protein-rich base without pre-soaking. If you have been wondering how to cook lentils in instant pot, you are in the right place. This guide covers everything from water ratios to seasoning, making your lentil dishes perfect every time.
Why Cook Lentils In An Instant Pot
Lentils are a powerhouse of nutrition, packed with fiber, protein, and minerals. Cooking them on the stovetop can take 30 to 45 minutes, plus you often need to watch the pot to prevent boiling over. The Instant Pot cuts that time in half and eliminates the need for soaking. It also locks in flavor and prevents the lentils from turning mushy if you time it right.
Another benefit is hands-off cooking. You simply add lentils, liquid, and seasonings, set the timer, and walk away. No stirring, no checking. This makes meal prep a breeze, especially on busy weeknights.
How To Cook Lentils In Instant Pot
Now let’s get into the step-by-step process. The exact method varies slightly depending on the lentil type, but the basics remain the same.
Step 1: Rinse Your Lentils
Always rinse lentils under cold water in a fine-mesh strainer. This removes dust, debris, and any tiny stones. Pick through them quickly to discard any shriveled or discolored ones. Do not skip this step, as it affects the final texture.
Step 2: Choose Your Liquid
Water works fine, but broth adds depth. Vegetable broth is great for a neutral base, while chicken broth gives a savory kick. For every cup of dry lentils, you will need about 1.5 to 2 cups of liquid. The exact ratio depends on how firm or soft you want them.
- For firmer lentils (like in salads): use 1.5 cups liquid per cup of lentils.
- For softer lentils (like in soups or dals): use 2 cups liquid per cup of lentils.
- For creamy lentils: use 2.25 cups liquid per cup of lentils.
Step 3: Add Seasonings
Lentils absorb flavors well, so season generously. Add salt after cooking, as salt can toughen the skins if added early. Instead, use aromatics like garlic, onion, bay leaves, or cumin. A splash of olive oil or coconut oil helps prevent foaming.
Step 4: Set The Instant Pot
Place the rinsed lentils, liquid, and aromatics in the inner pot. Close the lid, set the valve to sealing, and select the pressure cook (manual) setting. The cooking time depends on the lentil variety:
- Green or brown lentils: 15–18 minutes.
- Red or yellow lentils: 8–10 minutes.
- Black beluga lentils: 18–20 minutes.
- French green lentils (Puy): 20–22 minutes.
After the timer beeps, allow a natural pressure release for 10 minutes, then quick release any remaining steam. This prevents the lentils from bursting open.
Step 5: Season And Serve
Once the pressure is released, open the lid carefully. Stir in salt, pepper, and any additional seasonings like lemon juice, fresh herbs, or vinegar. Taste and adjust. The lentils will continue to thicken slightly as they cool.
Common Lentil Varieties And Their Uses
Not all lentils cook the same way. Knowing the differences helps you choose the right one for your dish.
Green And Brown Lentils
These are the most common. They hold their shape well after cooking but become tender. Use them in salads, stews, or as a side dish. They have a mild, earthy flavor.
Red And Yellow Lentils
These split lentils cook very quickly and break down into a soft, almost mushy consistency. They are ideal for soups, dals, and purees. They have a slightly sweet, nutty taste.
Black Beluga Lentils
These small, black lentils look like caviar. They stay firm and have a rich, earthy flavor. Perfect for salads or as a garnish.
French Green Lentils (Puy)
These are similar to green lentils but smaller and firmer. They hold their shape exceptionally well and have a peppery flavor. Great for cold salads or side dishes.
Tips For Perfect Instant Pot Lentils
Even with a pressure cooker, small mistakes can ruin your lentils. Here are some pro tips:
- Do not overfill the pot. Lentils expand and foam, so keep the liquid level below the max fill line.
- Add a teaspoon of oil or butter to reduce foaming and prevent the vent from clogging.
- If you forget to rinse, the lentils may have a slightly gritty texture.
- For a thicker consistency, mash a few lentils against the side of the pot after cooking.
- If your lentils are too watery after cooking, use the sauté function to simmer off excess liquid.
Flavor Variations
Lentils are a blank canvas. Here are three easy ways to change them up:
Indian-Style Dal
Add 1 teaspoon each of cumin seeds, mustard seeds, and turmeric to the pot. After cooking, stir in a tadka (tempered oil) of garlic, ginger, and dried red chilies.
Mediterranean Lentils
Cook with a bay leaf, a cinnamon stick, and a splash of olive oil. After cooking, stir in lemon juice, fresh parsley, and crumbled feta cheese.
Smoky Lentils
Add 1 teaspoon of smoked paprika, 1/2 teaspoon of cumin, and a pinch of cayenne. Finish with a splash of apple cider vinegar.
How To Store And Reheat Cooked Lentils
Cooked lentils keep well in the fridge for up to 5 days. Store them in an airtight container with some of their cooking liquid to prevent drying out. To reheat, add a splash of water or broth and microwave or warm on the stovetop. You can also freeze lentils for up to 3 months. Thaw overnight in the fridge before using.
Frequently Asked Questions
Do I Need To Soak Lentils Before Using The Instant Pot?
No, that is one of the biggest advantages. Unlike dried beans, lentils do not require soaking. Just rinse and cook.
Can I Cook Lentils With Other Ingredients In The Instant Pot?
Yes, but be careful with timing. If you add vegetables like carrots or celery, chop them small so they cook at the same rate. Avoid adding acidic ingredients like tomatoes until after cooking, as they can slow down softening.
Why Are My Lentils Still Hard After Pressure Cooking?
This usually means they are undercooked. Check if your lentils are old, as older lentils take longer to soften. Also, ensure you used enough liquid. You can always add more liquid and pressure cook for an additional 2–3 minutes.
Can I Use The Instant Pot To Cook Lentils Without A Pressure Cooker Function?
Yes, you can use the sauté function to simmer lentils, but it will take longer and require monitoring. The pressure cooker function is faster and more consistent.
How Do I Prevent Lentils From Foaming Over In The Instant Pot?
Add a teaspoon of oil or butter to the pot. Also, do not fill the pot more than halfway with liquid and lentils combined. A natural pressure release also helps reduce foaming.
