# Expert Tips:

01 -
  • The lentils become perfectly tender without turning mushy, creating a satisfying texture that makes you forget this is entirely plant based
  • Leftovers taste even better the next day, making it the ultimate meal prep friend for busy weeks
02 -
  • The lentils continue cooking in the oven, so remove them from the stove when they are slightly firmer than you would want for soup
  • Do not skip the resting period because this allows the casserole to set and makes serving much neater
03 -
  • Add a splash of balsamic vinegar during the last 5 minutes of stovetop cooking for a subtle brightness that elevates the entire dish
  • Toast the dried spices in the hot oil for 30 seconds before adding the vegetables to wake up their essential oils
