Start by slicing the sausage and dicing the onion. Frozen green beans can go straight from the bag into the pot, which saves time. I like to have all ingredients ready before turning on the Instant Pot.
Add all ingredients into the Instant Pot, including chicken broth and seasonings. Seal the lid, set to manual for 6 minutes, and let the magic happen. Quick-release the steam once cooking is done to avoid overcooking.
Remove the lid carefully, give everything a gentle stir, and the dish is ready. The beans are tender, the sausage is perfectly cooked, and the flavors have melded beautifully. I usually taste and adjust seasoning at this stage.
