This Instant Pot potato soup is perfect for a cold winter night, whether you're looking for the easiest hands-off dinner or the coziest meal to feed a crowd.
Set Instant Pot to "Sauté" setting. Cook bacon and oil, stirring occasionally, until crisp, about 8 minutes. Using a slotted spoon, transfer bacon to a paper towel-lined plate, leaving fat in pot.
Add onion and cook, stirring occasionally, until softened, about 7 minutes. Add garlic and thyme and cook, stirring occasionally, until fragrant, about 1 minute more. Add potatoes, broth, and salt. Cover pot, then set to "Pressure Cook" on high and set timer for 8 minutes. Slow release pressure.
In a small bowl, whisk flour and half-and-half to create a slurry. Uncover pot and add slurry, sour cream, and pepper. Using an immersion blender, blend until some chunky bits of potato remain. (Alternatively, you can use a standard blender to blend about half of soup and return to pot.)
Set Instant Pot to "Sauté" setting. Cook, stirring frequently, until slightly thickened, 3 to 4 minutes.
Divide soup among bowls. Top with bacon, sour cream, cheddar, and chives.
