Heat Instant Pot to Sauté and add oil. When oil is shimmering, add sausage and onion and cook, breaking up sausage as it browns.
When sausage is browned, add farro, sweet potato, apple, cranberries, sage, parsley, bay leaf, salt and pepper. Pour water in and stir to combine all ingredients.
Place cover on Instant Pot and turn valve to seal. Select Pressure Cook (or manual setting, high pressure) for 10 minutes. When timer goes off, let the pressure naturally release (aka leave it alone) for 10 minutes. When 10 minutes has elapsed, quick release remaining pressure.
Stir gently to fluff and serve immediately garnished with fresh parsley
Notes
For added crunch and flavor, try adding a handful of toasted pecans or walnuts after it has cooked!
Choose a firm, tart apple such as Granny Smith. Peel, if desired.
If you use pork sausage which isn't as lean as turkey sausage, you may want to drain the excess fat before adding the rest of the ingredients to the Instant Pot.
