Step 1

Cook bacon in a medium skillet over medium-high heat until crispy, stirring occasionally. Drain off grease and transfer to a large bowl (reserving some for garnish.)

Step 2

In the same skillet, melt the butter. Add the onion and celery; saute until vegetables are tender, about 5 minutes. Stir in the garlic until fragrant, 20 seconds. Transfer to the bowl with the bacon.

Step 3

Add to the bowl the mashed potatoes, cheese, flour, egg, mustard, pepper, and a few dashes of hot sauce; stir to combine.

Step 4

Form mixture into 8 (1/3-cup) patties, about 1/2 to 3/4-inch thick.Place them on a lightly greased plate, cover, and transfer to the refrigerator for 20 to 30 minutes.

Step 5

Heat oil in the skillet over medium heat. Fry patties until golden brown, 2-3 minutes per side.

Step 6

Serve immediately with a dollop of sour cream, chives, and reserved bacon.
