Begin by slicing your chosen bread into thick, even slices, ensuring they're sturdy enough to soak up the milk mixture without becoming too soggy.
Preheat your air fryer to 375°F (190°C) to ensure even and quick cooking.
In a mixing bowl, combine your choice of non-dairy milk, cornstarch, maple syrup, vanilla extract, ground cinnamon, and a pinch of nutmeg and salt.
Whisk the ingredients together until the cornstarch is fully dissolved, and you have a smooth, homogenous mixture.
Dip each bread slice into the mixture, ensuring both sides are well-coated but not overly saturated. Allow excess liquid to drip off.
It's crucial to ensure that the bread is soaked just long enough to absorb the mixture but not so long that it becomes overly soggy and falls apart.
Lightly spray the air fryer basket with cooking spray or brush with melted coconut oil to prevent sticking.
Place the soaked bread slices into the basket, ensuring they're not overlapping.
Cook at 375°F (190°C) for about 6-8 minutes on one side until golden brown and slightly crispy.
Flip the slices and cook for another 6-8 minutes or until they've achieved a uniform golden hue and desired crispiness.
Once cooked, carefully remove the French toast slices from the air fryer.
Plate and serve immediately while hot. Top with your favorite fresh fruits, an extra drizzle of maple syrup, a dusting of powdered sugar, or any other preferred toppings.
