How do you know when a frittata is cooked?

The frittata is cooked when it's golden brown on top and the eggs are set in the middle.

Why did my frittata deflate?

It's normal for a frittata or quiche to puff up while it cooks and then deflate a little when it's removed from the heat. This air fried frittata will deflate a little and pull away from the sides of the pan as it cools. It shouldn't sink in the middle though. That's a sign that it may not be fully cooked in the middle.

Can you use milk instead of cream in a frittata?

You can substitute with dairy milk or plant-based milk but heavy cream is best for the creamy and fluffy texture.

Creamy and Fluffy Air Fryer Frittata with Spinach, Bacon and Cheese

Description

Air Fryer Frittata is creamy and fluffy with spinach, bacon and Swiss cheese. It’s quick to assemble and hands off as it cooks in the air fryer!

Ingredients

6 large eggs
3 tablespoons heavy cream
1/2 teaspoon fine sea salt
1/4 teaspoon ground black pepper
1/2 cup cooked crumbled bacon (about 4 slices)
1/2 cup chopped baby spinach
1/2 cup chopped red bell pepper
1/2 cup grated Swiss cheese
1 green onion, sliced

Instructions

Grease a 7-inch round pan with non-stick cooking spray.
In a medium-sized bowl, whisk together the eggs, cream, salt and pepper.
Place the bacon, spinach, red pepper, cheese and green onion in the bottom of the prepared pan.
Pour the egg mixture over top. Use a fork, if necessary, to move the fillings around to make sure they’re spread out evenly.
Carefully place the pan in the air fryer basket and air fry at 280F for 21-24 minutes, or until the frittata is golden brown on top and the egg mixture is set in the middle.
Use oven mitts to carefully remove the pan from the basket. Let cool for a few minutes. The frittata will set up more and pull away from the sides of the pan, making it easier to slice and remove pieces.

Notes

Use a pan that fits your air fryer. I used a 7-inch round cake pan that fits perfectly in a 5.8 quart air fryer. If you use a smaller pan, your frittata will be thicker and will take longer to cook.
I don’t recommend covering the frittata with foil as this will block the flow of air that helps the frittata cook and brown on top.
As air fryers can differ, you may need to adjust the temperature and air frying time slightly for your brand or model.
