The pressure cooker offers a highly efficient method for preparing lentils, dramatically reducing the time required compared to traditional stovetop boiling. This appliance uses steam pressure to raise the boiling point of water, resulting in faster cooking and a more consistent final texture. Achieving perfectly cooked lentils, whether for a firm salad or a soft puree, is easily accomplished by leveraging the speed and control of the modern pressure cooker. This method is a reliable solution for quickly integrating nutritious legumes into any meal plan.
Prepping Lentils and Liquid Ratios
Before pressure cooking, thoroughly rinse the lentils under cool running water to remove dust, debris, or small stones. While soaking is optional, it is not required for achieving proper tenderness under pressure. If you choose to soak, a brief 30-minute soak is sufficient.
Properly measuring the liquid ensures the lentils cook evenly and do not scorch. A standard liquid-to-lentil ratio for pressure cooking is 2 to 2.5 parts liquid for every 1 part dry lentils. For example, one cup of dry lentils requires two to two and a half cups of water or broth. This measurement accounts for the steam and the amount the lentils will absorb.
Add the liquid, rinsed lentils, and any desired aromatics or seasoning to the pot. Delay adding salt or acidic ingredients, such as vinegar or tomatoes, until after the pressure cooking is complete. Acidic ingredients can inhibit the softening of the lentil’s outer coat, potentially causing uneven texture.
Step-by-Step Pressure Cooking Method
Securely fasten the lid and set the steam release valve to the ‘Sealing’ position. The cooker will heat up, building pressure until it reaches the designated High Pressure setting. Once full pressure is reached, the appliance begins the programmed cook time countdown.
After the timer concludes, the method used to release the pressure significantly influences the final texture. There are two methods for releasing the built-up pressure: Natural Pressure Release (NPR) and Quick Pressure Release (QPR).
NPR involves turning off the heat and allowing the pressure to dissipate slowly. This method is preferred for softer textures, like soups or purees, as the lentils continue to gently cook during depressurization. QPR involves manually venting the steam immediately after cooking, rapidly halting the process. QPR yields a firmer, more intact lentil, suitable for salads or side dishes.
Detailed Timing Guide by Lentil Type
The duration of cooking under high pressure varies considerably based on the specific type of lentil and the desired level of tenderness. Varying the cook time by just one minute can be the difference between a perfectly firm lentil and one that begins to break down.
Red Lentils (Masoor)
Red lentils, often referred to as Masoor, require the shortest time because their outer seed coat is typically removed or very thin. These delicate lentils usually only need 1 to 2 minutes under high pressure. Use a Quick Pressure Release immediately, as they can easily turn into a puree if overcooked.
Brown and Green Lentils
These are the most common varieties and require moderate cooking time to become tender while retaining some shape. For a firm lentil suitable for salads, cook for 4 to 5 minutes at high pressure. For a softer texture suitable for stews or side dishes, increase the cooking time to 6 minutes. Use a Natural Pressure Release after the timer concludes to ensure complete softening.
Black Lentils (Beluga)
Black lentils have a slightly thicker skin and benefit from a longer cook time. To achieve a tender but still intact lentil, 7 to 8 minutes at high pressure is recommended. These lentils hold their shape well, making them a good option for grain bowls and cold preparations.
French Green (Puy) Lentils
French Green or Puy lentils have the longest recommended pressure cooking time. They are valued for maintaining their shape and firm texture, even when fully cooked. These lentils require 9 to 10 minutes under high pressure to fully soften. To preserve their distinct structure, use a Quick Pressure Release immediately after the designated time.
Troubleshooting Texture and Storage
If the cooked lentils are too firm or underdone after pressure release, add a small amount of extra liquid to the pot. Secure the lid and cook for an additional 1 to 2 minutes under high pressure. Follow this brief second cook with a short Natural Pressure Release.
If the lentils are too mushy, they can still be salvaged for other preparations. Overcooked lentils are excellent for blending into smooth soups, thickening sauces, or mashing into dips. Cooked lentils store well in an airtight container in the refrigerator for three to five days. For longer preservation, they can be frozen in small portions for up to six months.
