Hearty Baked Potato Soup

Why This Hearty Baked Potato Soup Works

In the oven, the potatoes cook slowly all the way through, so the insides get fluffy and dry instead of watery. That baked potato center has a lot of starch, and once it’s scooped out and mashed into the pot, it thickens the soup in a natural way. The soup doesn’t need a ton of extra thickeners because the potato flesh soaks up the liquid and swells, so the soup ends up hearty and not gluey.

In the pot, the butter and flour cook together first, so the flour doesn’t taste raw and can grab onto the milk and broth. As the pot warms, that mixture starts to thicken, and then the mashed potatoes go in and push it even further toward a chowder-like texture. Cheese and sour cream melt in and smooth everything out, so it feels rich and creamy. Bacon goes in at the end and on top, so it stays a bit crisp instead of going soggy inside the soup.

Mistakes To Avoid

Pulling the potatoes from the oven too early leaves them hard in the center, so when the flesh is scooped and mashed, it stays lumpy and slightly raw. In the soup, those pieces never really soften and the whole pot ends up with chewy chunks instead of a smooth, creamy texture.

Letting the roux sit too long without whisking in the milk and broth can make it dark and pasty. Once the liquid goes in, it doesn’t blend smoothly and the soup base turns grainy and can even taste a bit scorched, instead of thick and velvety.

Pouring the milk and broth in all at once instead of gradually often leads to stubborn lumps. The flour mixture clumps up, and even with more whisking, the soup keeps tiny flour balls that stay gummy in the finished bowl.

Boiling the soup hard after adding the sour cream and cheese can cause the dairy to split. The fat separates, the soup looks curdled, and the texture turns slightly oily instead of evenly creamy.
