Melt butter in Instant Pot on saute mode. Then, stir in the flour until a roux forms. Add the onions, carrots, and garlic; saute until the onions become translucent and soften for about 10 minutes.
Deglaze the pot with chicken broth and bring the mixture to a boil on saute mode.
Stir in the white pepper, kosher salt, parsley, chipotle powder, and potatoes. Secure the lid and set the Instant Pot to manual high pressure for 7 minutes. Then, allow the pot to release naturally for 10 minutes.
Remove the lid, and stir in the milk and heavy cream. Then, use an immersion blender to break up the potatoes.
Taste and season with salt and pepper. Garnish with more cheddar cheese, and enjoy.
Notes
Expert Tips:
Cut the potatoes the same size (about 1-inch thick) to ensure they cook at the same rate.
Avoid a burn notice by deglazing the pot with chicken broth, and be careful to scrape up any stuck-on bits from the bottom.
If you prefer chunky potato soup, skip the immersion blender step. Instead, serve the soup as is, or you can process half the mixture. You can also use a potato masher, resulting in thick and creamy potato soup.
