Preheat oven to 400 degrees.

Cook bacon until crispy, then remove from pan and let cool. Finely chop.

Line a baking sheet with parchment paper.

Next, separate egg yolks and whites.

Place whites in a stand mixer with whisk attachment. Beat eggs whites on high speed until stiff peaks form, about 2 minutes or so.

Fold cheese, half of the bacon, and half of the chives into eggs whites.

Scoop eggs whites onto parchment lined baking sheet, making four mounds. Make an indentation in the eggs white for the yolk.

Bake egg whites for 3 minutes at 400 degrees and then remove from oven. Next place the egg yolks in the indentation in the egg whites. Bake for an additional 3-4 minutes. Remove from oven.

Finally, top with remaining chopped bacon, chives, salt, and pepper.
