First, peel the skin, wash then dice up the potatoes and throw them into the crockpot.
Then, dice the onion and add into the crockpot.
To the side, measure out the chicken broth in a measuring cup. Now, add the cornstarch into the measure cup and use a fork to whisk it into the chicken broth until dissolved. Next, pour it directly over the potatoes and onions into the crockpot.
Season the potato soup with salt and pepper. Go lightly if a beginner because you can always add more later, you can't take it out.
Cook on high for 2 hours then give the soup a stir. Comeback at 3 hours and turn the soup to warm. You can now mix in the heavy cream into the soup then taste for seasoning. Quick tip*, you can take out half the soup and blend it until smooth. This is optional because the cream is what makes the soup creamy and not blended potatoes.
Allow to sit on warm for 30 minutes before serving. Garnish with cheese, bacon bits and chives.
Notes
*Blending the soup is optional but you risk air bubbles which don't change the taste or texture. They tend to go away after the heavy cream is added.
