Step 1

Set your instant pot to saute. Once hot, add a few drops of water and cook the onions until translucent, then add the garlic and cook for one minute longer. Press the KEEP WARM/CANCEL button.(This sautéing step adds a little more flavour but you can skip it if you are short on time.)

Step 2

Add everything else to the Instant Pot except the green beans and arrowroot/cornstarch.

Step 3

Set the Instant Pot to 20 minutes on MANUAL high pressure and allow the pressure to release naturally after this time.

Step 4

Press KEEP WARM/CANCEL, remove the lid and press SAUTE. Put the arrowroot/cornstarch into a small bowl or cup and mix into it a few tablespoons of water to make a thickish but pourable slurry. Pour it into the Instant Pot stirring as you go.

Step 5

Add salt and pepper to taste then add the green beans and cook for about 5 minutes until they are tender and the gravy has thickened.

Step 6

Serve immediately.
