Don't skip the garlic sear – it builds depth. Pat chicken dry to avoid watery texture. Add cream and cheese at the end to prevent curdling. Use Yukon Gold potatoes for best texture. Don't crowd the slow cooker; a 6-quart is ideal. Leftovers keep 4 days in the fridge. To freeze, remove potatoes first. Reheat gently in a covered skillet or microwave in bursts.
