Instructions
After reserving the 1 cup of juices from the canned green beans, mix the teaspoon of Mushroom Better Than Bouillon in with it until it dissolves.
Add the green beens and cup of green bean-shroom juice to the Instant Pot. Smooth out the beans with a spatula. If using, top with the mushrooms. Secure the lid, move the valve to the sealing position, hit Pressure Cook or Manual at High Pressure for 1 minute. Quick Release when done.
Hit Cancel followed by Sauté and Adjust so it's on the More or High setting. Add the cream, shredded mozzarella (see Jeff's Tips), and herb cheese. Stir until all is melded together and well combined. Hit Cancel to turn the pot off.
Stir in 1 1/2 cups of the fried onions. Then, top with the remaining fried onions and serve. Or...
For a crispy finish: Top with the remaining fried onions, add the air fryer lid, hit Broil (400°) for 5 minutes and serve. Or, you can transfer to a casserole dish, top with the remaining fried onions and broil until browned (just keep an eye on it as all ovens vary).
