# Expert Advice:

01 -
  • It comes together faster than you'd expect for something this filling and sophisticated.
  • The double lentils create layers of flavor and texture that keep each spoonful interesting.
  • You can make a huge batch and actually enjoy eating the leftovers even more the next day.
02 -
  • Don't skip the browning step for the mushrooms—it's the difference between a good soup and one that tastes restaurant-quality.
  • If your lentils or barley aren't tender after the suggested time, it's usually because your heat is too high or your broth wasn't hot enough when you added it; gentle simmering is key.
03 -
  • Rinse your lentils and barley before cooking—it removes surface starch and helps them cook more evenly.
  • If you're making this for someone with dietary restrictions, check your broth label carefully since not all vegetable broths are gluten-free, and use certified gluten-free grains if needed.
