Omelette Fry-Up: Can Extreme Heat Actually Cook Food?
30 Jun
Summary
- Temperatures must reach 60-75°C to coagulate egg proteins.
- Sun-exposed pans can exceed air temperature for cooking.
- Dark metal cookware efficiently absorbs solar radiation for heat.

A viral video from the Netherlands captures a man appearing to cook an omelette in a pan placed directly in the sun amid soaring European temperatures. Experts clarify that while ambient air temperatures of 40-45°C are too low to cook an egg, the surface temperature of a sun-exposed pan can become significantly hotter.
Egg proteins require temperatures between 60-75°C to coagulate and cook properly. Dark-colored metal pans, in particular, can absorb and retain solar radiation efficiently, reaching temperatures well above the surrounding air. This phenomenon explains how surfaces like metal, roads, and car interiors can become intensely hot during peak summer.
The video highlights the impactful solar heating effect on exposed materials. Factors such as direct sunlight exposure duration, pan material, color, and surrounding conditions influence the pan's final temperature. This effect is most pronounced in calm, sunny weather with dark metal cookware.
