Turn your oven on to 450°F (230°C) and cover a baking tray with parchment.
02 -
Separate the whites from the yolks. Put the whites in a big bowl and the yolks into small bowls or ramekins for easier use later.
03 -
Grab an electric mixer and beat the whites on high. It should take about 2 minutes until they form stiff peaks that stand when you lift the whisk.
04 -
Gently toss in the parmesan, bacon pieces, and green onion slices. Use a spatula to carefully fold the mix-ins without deflating the whites.
05 -
Scoop the fluffy egg white mix into 4 heaps on the lined baking tray. Press the back of a spoon in the center of each to create a small indent for the yolks.
06 -
Pop the tray into your hot oven and bake for 3 minutes until the whites start firming up and get a little golden.
07 -
Take the tray out of the oven. Gently slide a yolk into the middle of each egg white nest.
08 -
Put the tray back in the oven for 3 to 5 minutes. Cook less for softer yolks and longer for firmer ones.
09 -
Take the tray out of the oven, sprinkle with a little more salt, pepper, or green onions if you want. Serve them warm and enjoy right away.
