Preheat the oven and prep the pan: Heat your oven to 425°F (220°C). Line a baking sheet with parchment and lightly oil or spray it to prevent sticking.
Separate the eggs: Carefully separate whites and yolks.
Place yolks in individual small bowls or a muffin tin cavity so they stay intact. Put the whites in a clean, dry mixing bowl.
Add stabilizer and season: Add cream of tartar and a pinch of salt to the whites. This helps them whip tall and stay fluffy.
Whip the whites: Using a hand mixer or stand mixer, beat on medium-high until stiff peaks form, about 2–4 minutes.
The peaks should stand straight up when you lift the beaters.
Fold in extras (optional): Gently fold in cheese and herbs with a spatula. Keep a light hand so you don’t deflate the whites.
Form the clouds: Spoon the whipped whites into four mounds on the baking sheet. Use the back of the spoon to make a small well in the center of each mound.
Bake the whites: Bake for 3–4 minutes, just until the edges start to barely color.
This sets the structure before adding the yolks.
Add the yolks: Remove the sheet from the oven and gently nestle one yolk into each well. Season with salt and pepper.
Finish baking: Return to the oven for 3–4 minutes more for runny yolks, or 5–6 minutes for jammy yolks. Watch closely—yolks set quickly.
Serve right away: Slide a spatula under each cloud and plate.
Add a drizzle of olive oil, extra herbs, or a pinch of chili flakes if you like.
