Method
Crisp the pancetta
- Cook pancetta in a large pot until crispy. Remove and set aside.
Build the roux and base
- Melt butter in the same pot, then sauté onions for 8 minutes until soft and golden. Keep the heat steady for even browning.
- Add garlic and cook for 1 minute. Stir constantly to prevent burning.
- Whisk in flour and cook for 2 minutes. The mixture should turn slightly pale and smell nutty.
- Gradually add chicken broth and half-and-half, whisking constantly, then bring to a simmer. Visual cue: the soup base should look smooth and slightly thickened.
Cook potatoes and finish
- Add potatoes and cook for 20 minutes until very tender. You should be able to easily mash a cube against the pot.
- Mash about half the potatoes, then stir in parmesan and sour cream until smooth. Visual cue: the soup becomes creamy with still-visible potato chunks.
- Season with kosher salt and black pepper. Serve immediately with crispy pancetta, fresh chives, and extra parmesan.
Notes
Pro tip: whisk the broth and half-and-half in gradually so the roux stays silky and smooth. Refrigerate leftovers in an airtight container for up to 4 days; reheat gently on the stove, adding a splash of broth if needed. Freezing is not recommended for best texture. For a lighter option, use low-fat half-and-half and reduce the sour cream slightly (texture will be a bit less rich).
