Method
Cook pancetta
- Add the diced pancetta to a large pot and cook until crispy, then remove and set aside.
- Keep the rendered fat in the pot for flavor; set the pancetta aside for topping later.
Build the creamy base
- Melt the butter in the same pot, then sauté the diced onions for 8 minutes until soft and golden.
- Add the minced garlic and cook for 1 minute, stirring to prevent browning.
- Whisk in the flour and cook for 2 minutes, scraping the bottom until it smells toasted but not burnt.
- Gradually add the chicken broth and half-and-half while whisking constantly, then bring the mixture to a simmer.
Cook and thicken
- Add the cubed Yukon gold potatoes and cook for 20 minutes, until very tender.
- Mash about half the potatoes in the pot, then stir in the grated parmesan and sour cream until smooth and creamy.
- Season with kosher salt and black pepper to taste, then serve topped with the crispy pancetta, fresh chives, and extra parmesan.
Notes
Pro tip: whisk steadily when adding broth and half-and-half so the roux stays smooth. Store leftovers in the fridge up to 4 days; freeze up to 2 months, though the texture may be slightly less silky after reheating. For a lighter version, use low-fat half-and-half and reduced-fat sour cream to cut calories while keeping the loaded flavor.
