Preheat Your Air Fryer: Preheat your air fryer to 350°F (175°C) for about 5 minutes.

Prepare the Bread Pudding: Take your leftover bread pudding slices or portions out of the refrigerator and place them on a plate. If the bread pudding has any toppings (like nuts or caramel), make sure they are evenly distributed on top.

Lightly Grease the Air Fryer Basket: You can use a bit of cooking spray or a brush with a small amount of oil to lightly grease the air fryer basket. This will help prevent sticking and enhance the crispy texture.

Place Bread Pudding in the Air Fryer: Carefully place the bread pudding slices or portions into the preheated air fryer basket, ensuring they are not overcrowded. If necessary, reheat in batches.

Reheat: Set the air fryer to 350°F (175°C) and reheat the bread pudding for 3-5 minutes. Keep a close eye on it as the exact time may vary depending on the thickness and size of the slices. You want the pudding to be heated through and slightly crispy on the outside.

Check for Doneness: After a few minutes, open the air fryer and check the bread pudding. If it's heated through and has a crispy exterior, it's ready to be served. If not, you can continue to air fry for an additional 1-2 minutes.

Serve Warm: Carefully remove the bread pudding from the air fryer basket, as it will be hot. Allow it to cool for a minute or two before serving. Optionally, drizzle with extra sauce or toppings if desired.
