The first time someone asked me for their eggs “over medium,” I nodded like I knew what that meant and served them something closer to a rubber disc. Sunny side up, over easy, over medium: for years they sounded like a secret code. They are not. Once you understand what is actually happening in the pan, the whole menu comes down to two questions: are the whites set, and how much does the yolk still wobble.
That second question is the whole game. Egg whites and yolks firm up at different temperatures, so the whites can be fully cooked while the yolk is still loose. The longer you cook, the more the yolk moves from runny to jellied to solid. Every style below is just a different stopping point on that path.
| Style | After the whites set | Yolk | Tell |
|---|---|---|---|
| Sunny side up | Don’t flip; cover to steam the top | Runny | Bright dome, never turned over |
| Over easy | Flip for just a few seconds | Runny | Light browning, cooked both sides |
| Over medium | Flip until the top barely wobbles | Jellied, not flowing | Set through, custardy center |
Over hard, fully cooked yolk, is the one style worth skipping here. As Nathaniel puts it in the video, you do not really need a guide for that one.
We’re not going to do an over hard because, well, you don’t really need any help over cooking an egg.

Get the whites and yolk right
A few small moves make all three styles easier.
The setup
- Crack each egg into a ramekin first. It keeps the yolk centered and catches any stray shell, so you place the egg instead of dropping it.
- Let the pan come up to a steady medium heat before the egg goes in, so the white sets on contact instead of spreading thin. In the video the pan reads about 160°F when the egg goes down.
- Egg whites set around 150°F, before the yolk does (about 158°F), which is exactly why you can get firm whites and a runny yolk. A whole egg is fully set near 165°F. To finish the top of a sunny side up without flipping, cover the pan to trap steam, and a few drops of water helps.
- Judge doneness by the yolk’s wobble, not the clock.
Why the wobble test works
Because whites and yolk set at different temperatures, the surface of the egg tells you what the inside is doing. A gentle shake of the pan is the only doneness check you need. A loose, jiggly yolk means runny. A yolk that quivers like a firm custard, not loose jelly and not solid, means over medium. Once the whites are set, the only decision left is how you finish: leave it and steam the top for sunny side up, flip it for a few seconds for over easy, or flip it until the wobble nearly stops for over medium.
We want fully set whites and a nice wobbly egg.

So the next time someone orders eggs a specific way, you do not need a code book. Set the whites, then read the yolk. The wobble tells you everything, and where you stop is the only difference between one style and the next.
