Dice the 1 lb ham, 2 sticks celery, 1½ lbs potatoes, and ½ lb carrots.
Add to the Instant Pot your diced items, 4 cups bone broth, 2 cups water, 1 tsp salt, and ½ tsp pepper.
Turn the vent to sealing and set on manual for 10 minutes on high pressure.
After the timer goes off, you can quick release the pressure but be very careful since the steam will burn you if your hand or arm touches it.
Then add the ½ cup heavy cream, ½ cup sour cream, and 6 oz sharp cheddar cheese.
Stir until fully combined, and the cheese has melted.
Your soup is ready to eat now or you can add desired toppings. We add chopped bacon and more shredded cheese.
