Method
Cook pancetta and sauté the aromatics
- Cook the pancetta in a large pot until crispy, then remove and set aside.
- Melt the butter in the same pot and sauté the onions for 8 minutes until soft and golden.
- Add the garlic and cook for 1 minute.
Thicken and build the creamy base
- Whisk in the flour and cook for 2 minutes.
- Gradually add the chicken broth and half-and-half while whisking constantly, then bring to a simmer.
Simmer, mash, and finish
- Add the potatoes and cook for 20 minutes until very tender.
- Mash about half the potatoes in the pot.
- Stir in the parmesan and sour cream until smooth.
- Season with the kosher salt and black pepper, then serve topped with crispy pancetta, fresh chives, and extra parmesan.
Notes
For the smoothest soup, whisk continuously when adding broth and half-and-half so the roux stays lump-free, and mash only about half the potatoes to keep chunky bites. Refrigerate leftovers up to 4 days; reheat gently over low heat to avoid splitting. Freezing is not recommended due to the dairy texture. For a dairy-light swap, replace half-and-half with evaporated milk and use low-fat sour cream (texture will be slightly less rich).
