A Simple Food Science Trick for Sunny-Side Up Eggs Without the Scrubbing
Eggs are a go-to breakfast at our house. They’re quick, protein-rich, full of healthy fats, and they _usually_ keep little bellies fuller a bit longer than cereal or toast alone. As a busy mom, I love meals that are simple, filling, and don’t leave me with a disaster in the kitchen afterward.
I love my tri-ply stainless steel cookware because it heats evenly, lasts forever, and works as a great nonstick alternative for families trying to reduce heavily scratched nonstick coatings in the kitchen. But every time I tried making sunny-side up eggs, I ended up spending the next 10 minutes scrubbing stuck-on egg bits off the pan.
After a lot of trial and error, I think I’ve finally cracked the code (no pun intended).

How I Make Sunny-Side Up Eggs in Stainless Steel Without Sticking
Short Instructions. Here’s exactly what I do:
- Light avocado oil spray
- Preheat pan
- Add butter
- Let it melt and heat briefly
- Add eggs
- Leave them alone for a minute
- Lower heat and cover (usually with whatever pot lid that’s sitting around- it doesn’t always fit exactly!)
The Super Simple Mom-Brain Science Version
Light Avocado Oil Spray
I lightly spray the pan with avocado oil using my Misto sprayer.
Stainless steel may _look_ perfectly smooth, but under a microscope it has tiny surface irregularities. When the pan preheats, the cooking surface becomes more evenly heated, helping the oil spread into those tiny imperfections and create a thin barrier between the eggs and the metal.
Egg proteins naturally want to bond to metal surfaces, especially if the pan is too cold or dry.
Avocado oil also works well because it tolerates moderately high heat without burning as quickly as some other oils.
Preheat the Pan
This step is huge.
If you add eggs to cold stainless steel, they’re much more likely to stick.
As stainless steel heats, the cooking surface becomes more evenly heated across the pan. This helps the oil spread more evenly and improves how the eggs release later.
You don’t need extremely high heat. Medium heat is usually enough.
Add Butter
Once the pan is warm, I add a pat of butter.
Butter contains fat, water, and milk solids. As it melts, the fat adds another layer between the eggs and the stainless steel while also improving flavor and browning.
The butter is not doing most of the nonstick work scientifically — the properly preheated pan and oil are doing most of that — but butter adds flavor and helps create a softer texture around the edges of the eggs.
Let the Butter Heat Briefly
I let the butter melt fully and heat for a few extra seconds before adding the eggs.
This gives some of the water in the butter time to evaporate and helps the fat coat the pan more evenly.
If the butter immediately turns dark brown, the pan is probably too hot.
Add the Eggs
I crack the eggs directly into the pan and then do something very difficult as a mom…I leave them alone.
Leave Them Alone for a Minute
This is where I used to mess up.
Egg proteins naturally stick a little at first while they cook. But once the proteins coagulate and set, they usually release more easily from the pan.
Trying to move them too early can make sticking worse.
Lower Heat + Cover
After the eggs start setting, I lower the heat and place a lid on the pan.
The trapped steam gently cooks the tops of the eggs without needing excessive bottom heat. Lower heat also reduces scorching and burnt residue on the pan.
Translation: less scrubbing later.
What Happens If You Use Only Oil or Only Butter?
After getting this method to work consistently, I started wondering whether I actually needed both the avocado oil and the butter. The answer is no, but they behave very differently in stainless steel because they’re chemically different fats.
If you use only oil, it’s usually the more reliable option for preventing sticking. I like avocado oil because it handles heat well and creates a stable cooking surface once the pan is properly preheated. Since oil is almost entirely fat, it helps coat the tiny surface irregularities in the stainless steel without burning as quickly.
Oil is also a little more forgiving if the pan gets slightly too hot. Cleanup tends to be easier too.
The downside, at least for me, is that eggs cooked in only oil sometimes feel like they’re missing the rich breakfast flavor that butter gives.
Butter tastes amazing with eggs, but it can be trickier in stainless steel. That’s because butter also contains water and milk solids. As it heats, the water evaporates and the milk solids begin to brown. If the pan gets too hot, those milk solids can burn and stick to the pan fairly quickly.
I think that’s one reason so many people get frustrated with stainless steel cookware. It’s often not the pan itself causing the issue — it’s overheated butter or moving the eggs too early before they naturally release.
From a cooking science perspective, if your only goal is the best possible nonstick performance, properly preheated stainless steel plus oil is usually the most reliable method. The oil is doing most of the heavy lifting when it comes to preventing sticking.
Using both avocado oil and butter creates a nice balance. The oil helps stabilize the cooking surface, while the butter adds flavor, richness, and softer browning without burning quite as quickly.
