Tips to cook flavorful stews in the Instant Pot.

  • You want to use less liquid when pressure cooking as the moisture doesnt evaporate out like in a saucepan. You can add more broth later while simmering after pressure cooking
  • It is ok if some of the liquid from the stew comes into the steamer. More flavor in the mash1!
  • Change up the fresh herbs for variation
  • This recipe is easily doubled, with or without the pip, with or without sweet potato. Just add 2 more mins of cooking time when doubling.

    I am always trying g to find recipes that combine vegetable protein while uping the veggies. I made this tonight for the family. It was delicious! Everyone cleaned their plates and hubby wanted seconds. He is not a huge fan of sweet potatoes but the flavor combo was perfect together. I will be adding this into my go to recipes list for sure. Thank you. 🙂

    We loved this! Used a mix of sweet potato and regular potato. So easy. I was amazed by how toothsome the mushrooms were after hanging out in the instant pot all that time.

    I’m also really loving your Everyday Kitchen cookbook. You’re a genius!

    I made this last night, along with your soft whole wheat dinner rolls and Mary McDougall’s corn butter. It was fabulous. My husband ate 5 rolls and 2 bowls of stew and sweet potatoes, lol.

    1. Richa says:

      wow awesome!

  8. Cassie Autumn Tran says:

    Sweet potatoes with stir-fried lentils and mushrooms–sounds like a wondrous combination to me! I definitely have to create a recipe like this sometime. Do you know if this recipe would also work on the stovetop?
