How to Make Sunny Side Up Eggs (Perfect Runny Yolk Every Time)
Cooking sunny side up eggs seems easy, but many people get it wrong. The bottom burns while the whites stay raw. Or the yolk gets a thin white film on top. These small problems can ruin the egg.
Sunny side up eggs are different because you do not flip them. This makes cooking the top part harder. However, once you understand how heat and steam work together, it becomes much easier to control the result. In this guide, you will learn what sunny side up eggs are, how to cook them the right way, and how to fix common mistakes.
Quick Answer: What Are Sunny Side Up Eggs?
Sunny side up eggs are fried eggs cooked on one side only. The whites are set, and the yolk stays fully runny on top.
This means the yolk is soft and flows easily when cut. This also means the egg is not flipped at any stage.
What Does “Sunny Side Up Eggs” Mean?
The name comes from how the egg looks.
The bright yellow yolk sits on top like the sun, while the whites spread around it.
The egg is not flipped during cooking. This keeps the yolk soft and runny. This is why the yolk stays visible and exposed on top.
What Do Sunny Side Up Eggs Look Like? (Perfect Yolk Guide)
Sunny side up eggs have fully set whites and a soft yolk.
The yolk should look bright, glossy, and smooth. It should not have a white layer on top.
The whites should be cooked but not burnt. The edges may be slightly crisp, but the center should be soft.

Visual Doneness Guide

Perfect Sunny Side Up Egg Checklist
A perfect sunny side up egg should have:
- fully set whites with no clear parts
- no raw egg white near the yolk
- a bright, glossy yolk
- a soft center that moves slightly
- no white film covering the yolk

Types of Fried Eggs (Sunny Side Up, Over Easy, Over Medium, Over Hard)
There are four main types of fried eggs:
- Sunny side up – cooked on one side, yolk fully runny
- Over easy – flipped, yolk runny
- Over medium – flipped, yolk soft and slightly thick
- Over hard – flipped, yolk fully cooked
Each type depends on how long you cook the egg and whether you flip it.
Sunny Side Up Eggs vs Over Easy (Key Differences)
| Style | Flip | Egg White | Yolk |
|---|---|---|---|
| Sunny side up | No | Fully set | Fully runny |
| Over easy | Yes | Fully set | Runny |
Sunny side up eggs are not flipped. Over easy eggs are flipped once. This small step changes how the top of the egg cooks. This is why sunny side up eggs rely more on heat and steam instead of flipping.
How to Make Sunny Side Up Eggs (Step-by-Step)
Follow these steps to cook sunny side up eggs correctly.
Heat the pan
Place a non-stick pan on low to medium-low heat. Let it warm for 1–2 minutes. Lower heat helps cook the egg evenly and prevents burning.
Add butter or oil
Add a small amount of butter or oil. Let it melt and spread.
Crack the egg
Crack the egg gently into the pan. Keep the yolk whole.
Cook the whites
Let the egg cook slowly. The whites should turn solid from the outside toward the center.
Control the top without flipping
Do not flip the egg. Instead, use heat and steam to cook the top lightly. If the whites near the yolk are still clear, cover the pan briefly. If the edges start cooking too fast, reduce the heat slightly.
Quick Cooking Cheat Sheet
| Step | What to Do | Time |
|---|---|---|
| Heat pan | Low to medium-low heat | 1–2 min |
| Cook whites | Let whites set slowly | 2–3 min |
| Cover (optional) | Use lid if whites near yolk stay raw | 30–60 sec |
| Finish | Remove when whites are fully set | — |
Perfect Sunny Side Up Eggs: What Makes Them Perfect?
A perfect sunny side up egg has:
- fully set whites
- no raw or clear parts
- a bright, glossy yolk
- a soft center that flows when cut
The goal is to cook the egg gently without overcooking the yolk. If the yolk turns dull or gets covered, the heat is too high or the egg cooked too long.
Once you control the heat and timing, this method becomes easy to repeat and gives consistent results.
Do You Flip Sunny Side Up Eggs?
No, you do not flip sunny side up eggs.
If you flip the egg, it becomes over easy or another style.
Sunny side up eggs must stay on one side to keep the yolk fully exposed. This is what makes them different from other fried egg styles.
How to Cook the Top Without Flipping (Lid Method Explained)
To cook the top without flipping, you can cover the pan with a lid.
The lid traps heat and steam. This helps cook the top of the egg gently, especially the whites near the yolk.
If the whites are not cooking evenly, covering the pan helps heat reach the top. This method prevents raw spots and keeps the yolk soft.

Lid vs No Lid Method (Best Way to Make Sunny Side Up Eggs)
There are two main ways to cook sunny side up eggs:
With lid
- cooks the top faster
- helps whites cook evenly
- keeps texture soft
Without lid
- gives crispy edges
- takes longer
- may leave top slightly undercooked
If your whites are not cooking fully, use a lid. If you want crispy edges, cook without a lid on low heat.
How Long to Cook Sunny Side Up Eggs (Time and Heat Guide)
- Cook for about 2–4 minutes
- Use low to medium-low heat
If the heat is too high, the bottom burns because the edges cook faster than the center.
If the heat is too low, the whites may stay raw.
Adjust heat slightly based on how the egg is cooking.

Why Your Egg Whites Don’t Cook Properly (And How to Fix It Without Burning the Bottom)
This is a common problem.
Whites stay raw
- heat is too low
- pan is not covered
- heat is not reaching the top
Bottom burns
- heat is too high
- edges cook faster than the center
How to fix it
- use medium-low heat
- cover the pan briefly
- cook slowly and evenly
If the whites near the yolk stay clear, covering the pan for a short time will fix the problem.
How to Know When Sunny Side Up Eggs Are Done
Look for these signs:
- whites are fully set
- no clear liquid remains
- yolk is soft and shiny
The yolk should still move slightly if you shake the pan. This confirms the egg is cooked correctly.
Common Problems When Cooking Sunny Side Up Eggs (And Fixes)
Whites are still raw
Cover the pan for a short time to cook the top.
Edges burn
Lower the heat and cook slowly.
Yolk gets a white film
Heat is too high or cooking time is too long.
Quick Fix Guide
- Whites still raw → cover pan for 30–60 seconds
- Bottom burning → reduce heat
- Yolk gets film → cook on lower heat
- Edges too crispy → use less heat and more control
