Preheat oven to 400 degrees F. Line a baking sheet with parchment paper, set aside.

Lay out puff pastry sheet on a clean surface. If needed, give it a gentle roll with a rolling pin if puff pastry is uneven. Cut in half, horizontally and vertically, to create 4 squares. To score the pastry dough, use a knife to cut a shallow ½-inch border along the edges of each square, making sure to not cut all the way through. This will help the edges rise when baking. Transfer to parchment lined baking sheet.

Lay bacon strips onto puff pastry squares to resemble an X. Using the back of a spoon, push down onto the center of the squares to make a deep indentation. This will help the eggs stay in the center.

Carefully crack one egg into the center of each square. It's okay if some of the egg white oozes to the side. Sprinkle with salt. Place into oven and bake for 18-20 minutes, or until edges of puff pastry are golden and crisp. Garnish with chives.
