Add the liner to your Instant Pot, add the butter, and press the 'saute' button. Once the butter's melted stir in the onion, carrot, and celery. Cook, stirring often, just until the veggies have begun to soften- roughly 5 minutes.
1 tbsp butter, 1 small yellow onion, 1 large carrot, 1 stalk celery
Add the garlic, broccoli, broth, and nutmeg to the pot- stirring them to evenly incorporate.
4 tsp garlic paste, 4 cups fresh broccoli, 6 1/2 cups chicken broth, pinch ground nutmeg
Close the lid, set the vent valve to the 'sealed' position, and pressure cook on 'HIGH' for 2 minutes. When done perform a 'quick release' by carefully opening the vent valve to release the trapped hot steam.
In a small mixing bowl mix the cheese, flour, and cornstarch together until evenly combined.
3 1/2 cups shredded cheddar cheese, 2 tbsp flour, 2 tsp cornstarch
Open the lid, press the 'saute' button, and add the cheese stirring it into the soup until evenly combined and completely melted.
Stir in the heavy cream and continue cooking the soup, stirring occasionally, just until the soup's thickened some.
1 cup heavy whipping cream
Salt and pepper to taste, then serve warm & enjoy!
