I went off script with this. as I was making it, I realized that there were no seasonings listed lol so I followed the instructions up until adding the potatoes into the crock pot.
at this point I added carrots and celery, though instead of carrots I think broccoli would have been nice. the veggies are totally up to your discretion I just wanted a little more instead of just potatoes.
I also added salt, pepper, oregano, rosemary, a bay leaf, onion Powder, and garlic Powder.
when adding the sour cream mixture I also added cheddar cheese into the soup, though it's not really necessary.
when serving I added parmesan cheese because why not.
