This Air Fryer Spring Vegetable Frittata with Asparagus and Leeks is a fast, fresh way to get breakfast or brunch on the table without turning on the oven. Tender asparagus, sweet leeks, and a little cheese bake into a fluffy center with lightly set, golden edges.
Why This Air Fryer Recipe Works
The air fryer acts like a mini convection oven, so the frittata cooks evenly without the long preheat time of a full-size oven. Circulating heat also helps set the top quickly, which keeps the eggs from turning rubbery.
Sautéing the leeks first is the small step that makes a big difference. It softens them, tames any sharp bite, and prevents watery veggies from weeping into the eggs.
- Quick cook time with consistent heat
- Spring vegetables stay bright and tender
- Easy to slice for meal prep or brunch boards
Ingredients You’ll Need
This recipe is written for a 7-inch round cake pan or air fryer-safe baking dish that fits your basket. If you use a different pan size, check doneness early and often.
- 6 large eggs
- 2 tablespoons milk or half-and-half
- 1/2 teaspoon kosher salt
- 1/4 teaspoon black pepper
- 1 small leek (white and light green parts only), halved and thinly sliced, rinsed well
- 1 tablespoon olive oil or butter
- 1 cup asparagus, trimmed and cut into 1-inch pieces (tips reserved for the top if you want a pretty finish)
- 1/3 cup shredded cheese (Gruyère, cheddar, or feta)
- 1 tablespoon chopped chives or parsley (optional)
Optional but helpful: nonstick spray for the pan, and a pinch of red pepper flakes if you like a little heat.
How to Make Air Fryer Spring Vegetable Frittata with Asparagus and Leeks in the Air Fryer
1) Prep the pan.
Lightly grease a 7-inch round cake pan (or similar air fryer-safe dish). Set aside.
2) Soften the leeks and asparagus.
Heat olive oil or butter in a skillet over medium heat. Add sliced leeks with a pinch of salt and cook 4–5 minutes, stirring, until soft. Add asparagus pieces and cook 2–3 minutes just to take the raw edge off (they’ll finish cooking in the air fryer). Let the vegetables cool for a minute so they don’t scramble the eggs.
3) Mix the eggs.
In a bowl, whisk eggs, milk, salt, and pepper until well combined and slightly frothy. Stir in the cheese and herbs (if using).
4) Assemble.
Spread the leek-asparagus mixture evenly in the prepared pan. Pour the egg mixture over the vegetables. If you reserved asparagus tips, place them on top for a clean, springy look.
5) Air fry.
Preheat the air fryer if your model requires it. Place the pan in the basket and cook until the center is just set and the edges are lightly golden.
6) Rest and slice.
Let the frittata rest 5 minutes before slicing. It will finish setting as it cools and slice more cleanly.
Air Fryer Time and Temperature
Use this as a baseline and adjust for your air fryer and pan depth.
- Temperature: 320°F
- Time: 14–18 minutes
Start checking at 12 minutes if your pan is shallow. The frittata is done when the edges look set and the center jiggles only slightly; a knife inserted near the center should come out mostly clean.
Tips for the Best Results
Keep the vegetables from watering out the eggs by cooking them briefly first and avoiding overloading the pan. If your leeks seem wet after rinsing, pat them dry before sautéing.
For a more tender texture, stick with 320°F instead of blasting it at higher heat. Higher temps brown faster but can tighten the eggs before the middle sets.
- Grease the pan well so slices release easily.
- Don’t over-whisk; just combine until uniform and a bit foamy.
- If the top is browning too quickly, loosely cover the pan with foil for the last few minutes.
- Rest 5 minutes before slicing for cleaner wedges.
Variations and Substitutions
Swap what you have while keeping the same egg-to-filling balance. Aim for about 1 to 1 1/2 cups total cooked vegetables.
- Cheese: feta for tang, goat cheese for creaminess, or Swiss for a mild melt.
- Vegetables: add peas, baby spinach (wilt first), or sautéed mushrooms.
- Protein: a small handful of chopped ham or cooked bacon is great, but keep it light so the frittata still feels springy.
- Dairy-free: use unsweetened oat milk and skip the cheese, or use a dairy-free shredded cheese that melts well.
If you want a slightly crisper edge, use a metal cake pan (not glass) and preheat the air fryer for 3 minutes.
What to Serve With It
This frittata is hearty enough to stand alone, but it’s even better with something fresh and something crunchy.
- Simple arugula salad with lemon and olive oil
- Fresh fruit or berries
- Toast, English muffins, or roasted potatoes
- Salsa or a spoon of pesto on the side

Storage and Reheating
Cool leftovers fully, then store slices in an airtight container in the refrigerator for up to 4 days. Place parchment between slices if you’re stacking them.
To reheat, warm slices in the air fryer at 300°F for 3–5 minutes until heated through. If the top starts to darken, drop the temp to 280°F and extend by a minute.

FAQ
-
Can I make this air fryer frittata without a cake pan?
Yes, as long as you use an air fryer-safe baking dish that fits your basket and is at least 1 1/2 inches deep. Avoid paper liners alone for a pourable egg mixture. -
How do I know when a frittata is done in the air fryer?
The edges should be set and lightly golden, and the center should only wobble a little. A thin knife or toothpick near the center should come out mostly clean with no wet egg. -
Why did my frittata come out watery?
Usually it’s excess moisture from vegetables. Make sure the leeks are well-drained after rinsing and sauté the vegetables briefly to cook off some water before adding eggs. -
Can I use frozen asparagus?
You can, but thaw and pat it dry first. Frozen asparagus can release extra water, so a quick sauté or a couple minutes in the skillet helps prevent a soggy texture. -
Can I double the recipe?
It’s better to cook in two batches unless you have a larger air fryer and a bigger pan. A thicker frittata takes longer to set and may brown on top before the center finishes.
