Trim the crusts off the bread slices to make them easier to roll.
Use a rolling pin to flatten the bread slices. This makes them more pliable for rolling.
Spread a thin layer of strawberry jam on each flattened bread slice. Be careful not to overfill to avoid leaking during cooking.
Roll up the bread slices tightly from one end to the other. Press gently to seal the roll if necessary.
In a shallow dish, whisk together the eggs, milk, vanilla extract, and ground cinnamon until well combined.
Dip each bread roll-up into the egg mixture, allowing the excess to drip off. Optionally, you can sprinkle the roll-ups with granulated sugar for added sweetness and texture.
Preheat your air fryer to 375°F (190°C) if your air fryer requires preheating.
Grease the air fryer basket with butter or non-stick cooking spray to prevent sticking.
Place the roll-ups in the air fryer basket in a single layer, making sure they do not touch to ensure even cooking.
Cook for about 8-10 minutes, or until golden brown and crispy. You might need to flip them halfway through the cooking time for even browning.
Carefully remove the French toast roll-ups from the air fryer.
Dust with powdered sugar before serving, if desired.
