Ingredient Notes

Ingredients for lentil mushroom soup.
  • Vegetables - onions, carrots, celery, garlic and mushrooms are the star veggies!
  • Spices - salt, black pepper and thyme.
  • Wine - used to deglaze the pan. It adds a bit of flavor but all of the alcohol will cook out!
  • Lentils - use regular lentils (brown lentils) for this recipe.
  • Vegetable broth - you'll need a combination of vegetable broth and water for this recipe. You can buy broth of try making your own veggie scrap broth!

Emily's Top Tip

"Don't add the salt or spices until after the mushrooms have cooked for 8-10 minutes. This will help prevent the mushrooms from becoming rubbery or difficult to eat."
