Melt butter in Instant Pot using the sauté function. Then, stir in the all-purpose flour until a blonde roux forms, for 10-15 minutes.
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, dried parsley, chipotle powder, and potatoes. Secure the lid and set the Instant Pot to manual high pressure for 7 minutes. Then, let the pot naturally release for 10 minutes, followed by a quick release.
Remove the lid, and stir in the milk and heavy cream. Use an immersion blender to process the soup until smooth or chunky, depending on your preference.
Taste and season with salt and pepper. Garnish with shredded cheddar cheese, and enjoy.
Notes
Expert Tips:
Cut the potatoes into 1-2 inch pieces to ensure they cook at the same rate.
Avoid a burn notice by deglazing the Instant Pot with chicken broth, and be careful to scrape up any stuck-on bits from the bottom before securing the dish and pressure cooking.
If you prefer chunky potato soup, skip the immersion blender step or only process half of the mixture. You can also use a potato masher instead, resulting in thicker potato soup.
