Crack the eggs into a mixing bowl. Add milk, heavy cream, sugar, vanilla, cinnamon, nutmeg, and salt. Whisk well until everything becomes smooth and fully combined.

Preheat your air fryer to 375°F (190°C) for about three minutes. A preheated basket helps the bread cook evenly and become crisp on every side.

Place one bread slice into the egg mixture. Coat both sides evenly without soaking too long. The bread should absorb flavor but still keep its shape.

Lightly spray the air fryer basket with cooking spray. Arrange the coated bread slices in a single layer without overlapping. Cook in batches if necessary.

Air fry for about five minutes. The bread should become lightly golden with crisp edges while the inside stays soft and fluffy.

Use tongs to carefully turn each slice. Air fry for another four to five minutes until both sides become evenly browned and crispy.

Remove the French toast when both sides are golden brown and the center feels fully cooked. Avoid overcooking because the bread may become dry.

Place the French toast on serving plates. Dust with powdered sugar. Add maple syrup, fresh berries, butter, or whipped cream before serving warm.
