I’ll be honest—when my neighbor first mentioned making a “cake” with spring onions, I thought she’d lost her mind. But one bite of this savory beauty and I was completely hooked. Now it’s my go-to party appetizer, and people always ask for the recipe (which used to be embarrassing because I had no idea what I was doing).
Why This Recipe Works
Here’s the thing about this spring onions roll cake—it’s basically the lovechild of a fluffy omelet and a savory crepe, rolled up with the most amazing green onion filling. What makes this work is that the batter stays light and airy while still being sturdy enough to roll without cracking. I learned the hard way that getting the right consistency is everything, but once you nail it, this becomes ridiculously easy to make.
Essential Ingredients
Good eggs are worth the splurge here—I use about 4 large ones, and trust me, farm-fresh makes a difference in both flavor and that gorgeous yellow color. Don’t cheap out on these if you can help it.
All-purpose flour (just 3 tablespoons) keeps things light. I used to add way too much flour thinking it would make the cake sturdier, but that just made it dense and sad.
Fresh spring onions are the star of the show—you’ll need about 6-8 stalks, and I always grab a few extra because someone inevitably snacks on them while I’m cooking (guilty as charged). The green parts get chopped fine for the filling, and honestly, this is where the magic happens.
A splash of milk (maybe 2 tablespoons) makes the batter silky, and a pinch of salt brings out all the flavors. I also keep some butter or oil handy for the pan—nothing fancy needed, just something to prevent sticking.
The Technique Section
Start by cranking your oven to 350°F and lining a jelly roll pan with parchment paper. Here’s where I used to mess up every time—make sure that parchment goes up the sides a bit, or you’ll be peeling cake off your pan later.
Separate those eggs like your life depends on it. Egg whites go in one bowl (make sure it’s squeaky clean), yolks in another. Beat the yolks with the flour, milk, and salt until smooth—takes maybe two minutes but makes all the difference.
Now for the fun part: whip those egg whites until they form soft peaks. This is your secret weapon for keeping the cake light and fluffy. I learned this trick from my neighbor—don’t overbeat them or they’ll get grainy and refuse to fold in nicely.
Gently fold the whites into the yolk mixture. I mean gently—think of it like folding laundry, not mixing cookie dough. Pour this gorgeous batter onto your prepared pan and spread it evenly. It should look smooth and pale yellow, like the world’s most delicious blank canvas.
Bake for about 10-12 minutes until it springs back when you touch it lightly. While that’s baking, chop your spring onions super fine and mix them with a tiny bit of salt. This takes maybe two minutes but adds so much flavor.
Here’s my secret: the second that cake comes out of the oven, flip it onto a clean kitchen towel and carefully peel off the parchment. Spread your spring onion mixture over the warm cake, then roll it up using the towel to help guide you. The cake goes from perfect to impossible-to-roll in about five minutes, so work quickly but don’t panic.
Troubleshooting Guide
Cake cracked when you rolled it? You probably let it cool too much—this needs to be rolled while still warm and flexible. If this happens (and it will), just call it “rustic” and move on with your life.
Filling fell out everywhere? That’s too much filling, and I’ve been there. In reality, I’ve learned to use less spring onion mixture than I think I need. Better to have a subtle flavor than a messy disaster.
Cake turned out dense? You likely overmixed those egg whites or didn’t fold gently enough. Don’t stress about this part—even a dense version still tastes amazing, just different.
Variations
When I’m feeling fancy, I’ll add some cream cheese to the spring onion mixture—makes it richer than a weeknight dinner probably needs, but it’s incredible for special occasions.
My summer twist includes finely chopped chives mixed with the spring onions, and around the holidays, I’ll sometimes add a tiny bit of garlic powder (though that’s totally optional and changes the whole vibe).
FAQ
Can I make this ahead of time? Absolutely, just wrap it tightly and store in the fridge. I usually move it to the counter about 30 minutes before serving to take the chill off.
What if I don’t have a jelly roll pan? Most cookie sheets work fine—just make sure it has sides. I’ve used a 9×13 baking dish in a pinch, though the cake ends up a bit thicker.
Does this freeze well? Don’t freeze this one—the texture gets weird and rubbery. Trust me, I learned this the hard way.
Closing Thought
I couldn’t resist sharing this because it’s one of those recipes that looks way more complicated than it actually is. The best spring onions roll cake nights are when everyone’s gathered around the kitchen, and this disappears before I can even get it properly sliced. It’s honestly become my signature dish, and that still surprises me.

Spring Onions Roll Cake
Description
A light, fluffy savory cake that’s easier to make than it looks and disappears faster than you’d expect
Prep Time: 15 minutes | Cook Time: 12 minutes | Total Time: 27 minutes | Servings: 6-8
Ingredients
- 4 large eggs, separated (room temperature works best)
- 3 tablespoons all-purpose flour
- 2 tablespoons milk
- Pinch of salt
- 6–8 fresh spring onions, green parts finely chopped (about 1/2 cup)
- Extra pinch of salt for the onions
- Butter or oil for greasing
Instructions
- Heat your oven to 350°F and line a jelly roll pan with parchment paper, letting it come up the sides a bit.
- In a clean bowl, beat egg yolks with flour, milk, and salt until smooth—about 2 minutes of whisking does it.
- In another squeaky-clean bowl, whip egg whites until soft peaks form (if you can wait that long—they look so pretty at this stage).
- Gently fold the whites into the yolk mixture, being as gentle as you can manage. Pour onto your prepared pan and spread evenly.
- Bake for 10-12 minutes until the top springs back when lightly touched. While it bakes, mix your chopped spring onions with a pinch of salt.
- The second it comes out, flip the cake onto a clean kitchen towel and carefully peel off parchment. Spread the spring onion mixture over the warm cake, then roll it up using the towel to guide you.
- Let it cool seam-side down for about 10 minutes before slicing.
Notes:
- Seriously, work quickly when rolling—warm cake is your friend here
- Every oven runs differently, so trust your eyes more than the timer
- Room temperature eggs whip better, but if you forgot to take them out early, just put them in warm water for a few minutes
Storage Tips:
- Wrap tightly and keep in the fridge for up to 3 days
- Don’t microwave leftovers—they turn rubbery
- Best served at room temperature or just slightly chilled
