Breakfast & Brunch
This air fryer egg tart recipe transforms a classic Hong Kong street food into a crispy, golden masterpiece with minimal effort.
The secret lies in wrapping tender egg custard in delicate tortilla shells, then air frying until the crust achieves that perfect crispy texture while keeping the yolk heart runny and vibrant.
I developed this method after struggling with uneven baking in the oven—until I discovered how the air fryer's precise heat delivers restaurant-quality results every time.
The beauty of this recipe is its simplicity: just a few ingredients come together to create a dish that's both impressive and foolproof. You'll need store-bought tortillas for the shells, a rich egg custard filling, and a pinch of salt to elevate the flavors.
The air fryer's compact cooking space means you can make these in batches without overcrowding, ensuring each tart gets the perfect amount of crispy love. No special equipment beyond what you likely already own.
What makes these air fryer egg tarts truly special is that signature contrast—crispy tortilla shells that shatter slightly with each bite, giving way to a velvety custard center with a molten yolk heart that pools like liquid gold.
The aroma alone will have everyone gathering around your kitchen, and the process is surprisingly quick, making it perfect for breakfast or brunch without the fuss. Once you try this method, you'll never go back to the oven for egg tarts again.
For those looking to adapt this recipe, you can easily substitute the butter in the custard with vegan butter for a plant-based version, or use whole wheat tortillas for added texture. The air fryer's versatility means you can experiment with fillings too—think savory cheese or even sweet variations.
Let's get started on creating these crispy, golden egg tarts that taste like they came straight from a bustling Hong Kong café.
Ingredients for air fryer egg tart
Four eggs, crispy tortillas, and a pinch of magic—here's what you need for golden air fryer egg tarts!
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 4 whole | Room temperature for best results |
| Unsalted Butter 🧈 | 2 tbsp | Cold, cubed for custard |
| All-Purpose Flour 🌾 | 1 tbsp | For custard thickening |
| Granulated Sugar 🍚 | 1 tbsp | Fine grain preferred |
| Salt 🧂 | ¼ tsp | Fine sea salt preferred |
| White Tortillas 🍞 | 4 whole | 6-inch diameter, store-bought |
| Vegetable Oil 🫒 | 1 tbsp | For brushing tortillas |
| Milk 🥛 | ¼ cup | Whole milk for creaminess |
| Cornstarch 🌾 | ½ tsp | For extra custard smoothness |
| Sesame Seeds 🌱 | 1 tbsp | Optional for garnish |
The tortillas are your secret weapon—6-inch white flour tortillas from Mission or La Tortilla Factory work best. Look for ones that are soft but sturdy enough to hold shape. If you can't find them, burrito-size tortillas cut into circles work too. The butter matters here—use unsalted European-style butter if you can, like Plugrá or Kerrygold. For the custard, room-temperature eggs blend smoother, so take them out of the fridge 15 minutes before mixing. The milk adds richness, but if you're making this vegan, swap it for full-fat coconut milk.
No sesame seeds? Poppy seeds or everything bagel seasoning works just as well. Short on butter? Coconut oil or vegan butter keeps this plant-based, though the flavor won't be identical. The cornstarch is optional but makes the custard silkier—if you skip it, just whisk the eggs and milk a little longer. For tortillas, whole wheat or spinach tortillas add texture but may crisp differently. The key is brushing them lightly with oil—don't drown them, or they'll get soggy. If your air fryer basket is small, make these in batches of two to avoid overcrowding, which kills crispiness.
Store-bought tortillas keep for 1 week in the fridge, but use them within 3 days for best results. The custard filling can be prepped 1 day ahead and refrigerated—just give it a quick stir before wrapping. Assembled tarts stay fresh for 2 hours at room temperature, but they're best eaten immediately after air frying. For leftovers, reheat in the air fryer at 300°F for 2-3 minutes—they won't be as crispy but still delicious. Freezing isn't recommended since the tortillas get tough.
Why You'll Love This Recipe
- No-Fuss Crispy Shell: I swear by this method—just melt butter in the air fryer, mix in flour and sugar until it’s almost doughy, then press it into the basket. No rolling pins, no stress, and that golden crust happens every single time. The secret? Let it sit for 5 minutes before baking—trust me, it’s worth it.
- Buttery Egg Perfection: That creamy, runny yolk with a shell so crisp it snaps? This recipe nails it. I crack the eggs right into the hot butter mixture (yes, really), and the air fryer cooks them just enough to set the edges without scrambling. Honestly, it’s the closest I’ve gotten to a bakery-style tart at home.
- Breakfast or Snack: Between us, these disappear fast. I make a batch on Sundays and keep them in the fridge for quick breakfasts or after-school snacks. They’re also my go-to for potlucks—no one expects egg tarts, but everyone asks for the recipe. (Pro tip: Sprinkle flaky salt on top right after baking.)
- Pantry Staples Only: Four ingredients, zero substitutions needed. The flour and sugar balance the richness of the butter, and the eggs add that familiar comfort without breaking the bank. I’ve made these for under $2 a dozen—my wallet and my taste buds both win. Plus, leftovers? They reheat in 3 minutes straight from the fridge.
Step-by-step instructions for air fryer egg tarts
Here's how to make crispy, golden tortilla shells with silky custard centers—every bite delivers that perfect yolk heart.
Make the Silky Custard Filling
In a medium saucepan, melt the 2 tablespoons unsalted butter over medium-low heat until it foams. Add the 4 whole large eggs, whisking constantly until fully combined and slightly thickened. This should take about 2-3 minutes—don't rush, or you'll risk scrambling the eggs.
Next, whisk in the ¼ cup milk, 1 tablespoon granulated sugar, ½ teaspoon cornstarch, and ¼ teaspoon salt until smooth. The mixture should look like a thick, pale yellow custard. Remove from heat and let it cool to room temperature—this ensures the filling sets properly in the tortillas. I like to place the pan in an ice bath for 5 minutes to speed up cooling while stirring occasionally.
Prepare the Tortilla Shells
Preheat your air fryer to 350°F—this is the magic temperature for crispy shells without burning. While it heats, brush each of the 4 whole white tortillas lightly with 1 tablespoon vegetable oil on both sides. Use a pastry brush for even coverage, focusing on the edges where the shells crisp first.
Cut each tortilla into 6 equal wedges (like a pizza), but don't separate them yet. You'll press these into the air fryer basket in a circular pattern, creating a compact, even shape. This arrangement ensures all pieces cook uniformly and develop that perfect golden crust. Keep the tortillas covered with a clean kitchen towel until ready to use—the oil will prevent them from drying out.
Assemble and Air Fry the Tarts
Arrange the tortilla wedges in a circular pattern in the air fryer basket, slightly overlapping the edges. Spoon 1 tablespoon of the cooled custard into the center of each wedge, then carefully fold the edges inward to create a half-moon shape. Press gently to seal, ensuring no custard leaks out—this keeps the filling contained for that classic egg tart experience.
Place the assembled tarts in the air fryer basket in a single layer, leaving ½ inch between each one for proper air circulation. Air fry at 350°F for 8-10 minutes, flipping halfway through, until the tortillas are deep golden brown and the custard is set but still slightly jiggly in the center. The edges should look crispy and slightly puffed—this is your cue that they're ready.
Garnish and Serve Warm
Remove the tarts from the air fryer and immediately sprinkle with 1 tablespoon sesame seeds for that classic crunch. Serve them warm while the custard is still silky and the yolk heart remains runny—this is the moment of truth! The contrast between the crispy, flaky tortilla shell and the creamy custard is what makes these egg tarts irresistible.
For the best experience, eat them within 10 minutes of air frying. If you need to reheat, pop them back in the air fryer at 325°F for 2-3 minutes until warmed through. The secret to perfect air fryer egg tarts lies in the crispy shells and the custard's perfect set—now you've got both!
Pro Tips For Making Air Fryer Egg Tart
- Preheat the Air Fryer: I learned this the hard way—skipping preheating means your egg tart crust ends up greasy instead of crisp. Hit 350°F (175°C) for 3 minutes first, then add your tarts. The extra heat jump starts the browning so you don’t get a sad, soggy bottom.
- Chill the Dough 20 Minutes: Sounds weird, but it works: Roll out your flour-butter-sugar dough and let it rest in the fridge while you preheat. Cold dough spreads less in the air fryer, so your tarts hold their shape better. (Yes, even if you're impatient like me.)
- Watch the Butter: Too much butter in the dough makes the crust greasy; too little makes it tough. Stick to 1/4 cup (57g) cold, cubed butter per 1 cup flour—mix it in until it’s pea-sized, not paste. Overworking it turns the dough into a sad, sticky mess.
- Brush Eggs Lightly: Don’t drown your tarts—just whisk 1 egg with a splash of water, then brush the tops very lightly before air frying. You want a golden finish, not a wet, rubbery shell. A pastry brush makes this easier, but even a damp paper towel works in a pinch.
Dietary considerations for air fryer egg tart
Vegetarian-Friendly Base
This recipe is naturally vegetarian, using eggs and dairy as the primary protein sources. The custard filling relies on 4 large eggs and 2 tbsp unsalted butter, while the tortilla shells provide the crispy texture.
For a plant-based version, simply swap the butter for vegan butter (like Earth Balance) and use whole milk coconut beverage instead of dairy milk. The tortillas remain the same, as they're typically vegetarian. 🌱
Gluten-Free Adaptation
To make these egg tarts gluten-free, replace the white flour tortillas with gluten-free corn tortillas (like Mission or La Tortilla Factory GF line). These hold shape well in the air fryer and crisp beautifully.
Keep all other ingredients identical—the custard filling remains safe for gluten-free diets. Always check labels to ensure no cross-contamination warnings exist on your tortillas.
Dairy-Free Options
For a dairy-free version, eliminate the butter entirely and use 1 tbsp coconut oil instead when making the custard. Replace the milk with unsweetened almond milk or oat milk—just note the custard will be slightly lighter.
The tortillas can remain the same, as they're typically dairy-free. Garnish with extra sesame seeds to add flavor depth without relying on butter.
Lower-Carb Modifications
Reduce the carb content by using low-carb tortillas (like Mission Carb Balance) or making your own almond flour tortillas. Skip the sugar entirely—the custard's natural sweetness from eggs balances well.
For extra richness, add 1 tbsp powdered erythritol instead. The air fryer method keeps the shells crisp without needing extra carbs for structure.
Allergen Considerations
This recipe contains eggs and dairy—the primary allergens. For nut-free kitchens, avoid cross-contamination when handling tortillas (some brands process in nut facilities). Sesame seeds are optional but contain sesame—omit if allergic.
Always check tortilla labels for allergen warnings, as processing facilities vary by brand. The air fryer method minimizes allergen spread compared to traditional baking.

Frequently asked questions
Can I use store-bought egg tart shells instead of tortillas?
While you can try it, the texture won't be the same! Store-bought shells are often pre-baked and won't get that perfect crispy air-fried crust. The tortilla method gives you that signature shatter-with-each-bite texture that defines air fryer egg tarts. If you're set on convenience, look for frozen egg tart shells and air fry them at 375°F for 5-6 minutes—just don't expect the same level of crispiness.
Why did my custard turn grainy or scrambled?
This usually happens when the eggs cook too quickly or aren't mixed properly. Always whisk constantly over medium-low heat until the mixture thickens slightly (about 2-3 minutes). If it still looks grainy, strain it through a fine-mesh sieve before assembling. For extra smoothness, chill the custard in an ice bath for 5 minutes while stirring occasionally.
How do I keep the yolk from cooking all the way through?
The secret is timing and temperature! Air fry at 350°F for no more than 8-10 minutes, and flip halfway through. The custard should be set but still slightly jiggly in the center—this means the yolk stays runny. If yours cooks through, try reducing the temperature to 340°F next time and check at 7 minutes. Serve immediately for that perfect molten center!
Can I make these ahead of time?
You can prep the custard 1 day ahead and refrigerate it, but assemble and air fry the tarts fresh for best results. The tortilla shells lose crispiness if made too early. For make-ahead convenience, wrap assembled (uncooked) tarts in plastic and refrigerate for up to 4 hours—just add 1-2 minutes to the air frying time when ready to cook.
What's the best way to reheat leftover egg tarts?
Pop them back in the air fryer at 325°F for 2-3 minutes—this restores some crispiness without overcooking. If you don't have an air fryer, use the oven at 350°F for 5 minutes on a wire rack. Microwaving makes them soggy, so avoid that method. For extra crunch, brush with a tiny bit of oil before reheating.
