Mix Ingredients: In a separate bowl, mix the water (or broth), soy sauce, and olive oil. Pour the wet ingredients into the dry mix, stirring until a dough forms. Knead the dough for about 2-3 minutes until it becomes elastic.
Shape and Wrap: Shape the dough into a loaf and allow it to rest for 5 minutes. Then wrap the seitan dough in parchment paper and then aluminum foil.
Set Up the Instant Pot: Place a trivet in the Instant Pot and add the simmering broth ingredients—vegetable broth, soy sauce, garlic cloves, and bay leaf. Arrange the seitan loaf on the trivet.Pressure Cook: Seal the Instant Pot lid and set to Manual/Pressure Cook on high pressure for 20 minutes. Once done, allow a natural pressure release for 10 minutes, then quick release any remaining pressure.
Serve: Let the seitan cool completely before slicing or shredding. Use in your favorite recipes as a substitute for meat.
