How To Cook Red Lentils

Stovetop Method
1 Rinse lentils under cool water until water drains clear.
2 Place the lentils and water in a large saucepan. Cover with water, and sprinkle with salt. Bring to a boil uncovered.
3 Reduce heat, and bring to a simmer. Cover and cook for 15 to 20 minutes, or until lentils are soft. 
4 Drain any excess water before serving.
Instant Pot (Pressure Cooker)
7 Rinse lentils under cool water until water drains clear.  
8 Place lentils in the instant pot, add the water and salt. Stir to combine.
9  Secure the lid, set the valve to sealing. Set the pressure to high, and the time to 4 minutes. 
10 Allow to naturally release pressure for 15 minutes, then turn the valve to quick release to release the remaining pressure. Remove the lid once all the steam has escaped.
