Preheat your oven to 350°F and line a baking sheet with parchment paper for easy cleanup (in case any cheese spread falls off the bread).
Slice bread loaf in half lengthwise.
1 loaf French bread
Place the bacon in a cold frying pan and turn the heat on to medium. Cook for about 8 to 12 minutes for thick cut bacon (if using thin cut, it’ll take less time), flipping over every couple of minutes. Remove the bacon from the frying pan and place onto a paper towel lined plate. Once cooled, roughly chop it.
4 strips bacon
Combine the cream cheese, sour cream, cheddar cheese, chopped bacon, and chives in a bowl.
4 strips bacon, 8 oz cream cheese, ½ cup sour cream, 1 ½ cup shredded medium cheddar cheese, 2 tbsp diced chives
Spread a thick layer of the cheese mixture onto each bread half. (It may be easiest to do this with a rigid rubber spatula or the back of a large spoon.)
Bake for 15-20 minutes until the cheese mixture is melted through. For extra toasty cheesiness, broil for 1-2 minutes, then remove from the oven.
While the bread is still hot, sprinkle crushed potato chips over the top.
½ cup crushed potato chips
Slice the bread into thick slices and garnish with extra chives, if desired.
