Set Instant Pot to saute mode and add butter. Let it melt, then add in onion and celery. Cook 2-3 minutes until soft.
2 cups Onion, 8 tablespoons Butter, 2 cups Celery
Add sausage to the pot. Cook until it browns, breaking it up as it cooks, for about 4 minutes.
1 pound Sage sausage
Season with garlic powder, poultry seasoning, salt, and pepper. Stir, then add in chicken broth and stir again.
1 ¼ cups Chicken broth, 1 tablespoon Poultry seasoning, 1 tablespoon Garlic powder, Salt, Pepper
dd chunks of Hawaiian rolls and gently stir to mix through.
12 Hawaiian rolls 1 package
Spoon everything from the Instant Pot into a greased dish small enough to fit into your Instant Pot.
Cover the dish tightly with foil. Create an aluminum foil sling by folding one long piece of foil into a strip and wrapping it around the dish so you can easily lift it out of the pot when needed.
Add water, then the trivet. Place the foil-wrapped dish on top of the trivet and close the lid. Cook on high pressure for 15 minutes. Quick release, then remove the dish from the pot and unwrap.
Top with sliced green onions, parsley, and gravy if desired. Serve, and enjoy!
