Why you’ll love this recipe

A great idea if you want a quick and healthy weekend breakfast is to make a frittata. Frittata is a type of crustless quiche that is usually made with some combination of vegetables, cheese, or leftover meat. It can be eaten warm or cold and if you use an air fryer, can be cooked in just minutes.

Frittata is a great way to use up any leftover bits and pieces in your fridge, whether they’re vegetables, bacon, or ham. It’s a nutritious main meal, packed full of protein and nutrients, and is a great way to add variety to your diet because you can really throw just about anything in and it’ll turn out great.  

Air frying is a great way to cook baked egg dishes, you should also check out my air fryer quiche, which is a version of this recipe with a flaky puff pastry crust and a ham and mushroom filling. Delicious!

Ingredients

Eggs

Use one egg per serving. Use the freshest eggs you can, as they really help with the texture of the frittata. Also when baking it is best to work with room-temperature eggs, so if you can, remember to get them out of the refrigerator around a half hour before you want to cook. 

Salt and pepper

A pinch of fine sea salt and a little freshly ground black pepper really bring out the flavors in this dish. 

Dijon mustard or mustard powder (Optional)

Mustard gives a slight kick to a baked cheese dish, and really improves the flavor (IMO). You can also use Dijon mustard or wholegrain mustard. I add about ¼ teaspoon per serving. You can skip this entirely if you are not a fan of mustard.

Cheese

You will need around ¼ cup of shredded cheese per serving. Shredded cheddar cheese, jack, or Swiss cheese are all great options. 

You can also add some cubes of feta cheese to make a cheese frittata.

Filling

For this recipe I used leftover potato, diced onion and fresh baby spinach. Feel free to use your choice of veggies, or whatever leftovers you have in the refrigerator. Think leftover roasted vegetables, leftover sausage or roast chicken.

You can use fresh vegetables to make it too, but I normally avoid anything you need to precook to cut down on prep time, so I usually stick to cherry tomatoes, bell peppers, spinach, zucchini, green onions, diced onions. 

Baking dish

You will also need some individual pie pans, approximately 4-4½ inches/ 10-12cm in diameter, or a single pie pan with a diameter of 8 inches/ 20cm, which serves 4.  

How to make frittata in an air fryer

This recipe is very straight-forward to make, there are just a few key steps to getting it just right:

1. Prep. Lightly grease your pie pans, and slice or dice the filling ingredients, and cook any that need to be pre-cooked (you should be able to quickly pre-cook any ingredients in the air fryer while you are preparing the egg if you need to).
2. Mix the filling. Whisk the eggs, mustard powder and salt in a bowl or large mixing jug (note: use a mixing jug if you have one large enough as it makes it much easier to pour the egg mixture into the pan when it is ready). Add the shredded cheese and the other filling ingredients and mix until combined. 
3. Preheat the air fryer to 320°F/160°C.  
4. Air fry the frittata. Carefully pour the egg mixture into the prepared pan(s), Do not over-fill it, be sure to leave at least ½ inch of space at the top as it will expand during cooking and could spill out of the pan. Place frittata in the air fryer basket, and air fry at 320°F/ 160°C for around 20-25 minutes until golden brown and 160°F/ 72°C in the center. 
5. Let the frittata set. The final step is to leave the frittata to set for at leave 10 minutes (longer if you want to cut nice clean slices). 

Serving ideas

I usually serve frittata for lunch or brunch. If it is a lunch a side salad makes a great addition, but for brunch I usually cook up a side of air fryer tomatoes while the frittata is setting. 

It is also great served with air fryer roast vegetables, which you can whip up while the quiche is resting (prep them while it is cooking, then air fry while you let the frittata set). 

Serve with a sauce such as fresh tomato salsa or Hollandaise sauce. Yum!

Storing and reheating

Store any leftover frittata in an air tight container in the refrigerator, and use within 3 days. Leftover frittata can be eaten cold, but you can also reheat it using one of the methods below. 

Reheating frittata in the air fryer

To reheat the frittata in the air fryer, place it in the air fryer basket (no pan necessary), and air fry at 360°F/180°C for 2-3 minutes until warmed through. 

Reheating frittata in the microwave

To reheat frittata in the microwave, place on a microwave-safe plate and microwave on high for 40-90 seconds (time will depend on how big the bit of frittata is and how powerful your microwave is).
