Arrange on a Microwave-Safe Plate: Place the burgers on a microwave-safe plate, ensuring they aren’t touching.

Cover with a Lid or Paper Towel: This helps trap moisture and ensures even heating.

Set Microwave Power: Adjust the microwave power based on wattage to avoid overcooking.

Microwave in Intervals: Heat the burgers in 30-second intervals, checking for doneness after each interval.

Check the Temperature: Use a food thermometer to confirm the burgers reach an internal temperature of at least 165°F (74°C).

Maintaining Burger Quality

Microwaving White Castle burgers can sometimes affect their quality, but here’s how to preserve their deliciousness:

Avoid Overheating: Overcooking can make the burgers dry and less flavorful. Keep a close eye on them.

Use a Lid: Using a microwave-safe lid or covering it with a paper towel helps maintain moisture.

Reheat in Batches: If you have several burgers, reheat them in smaller batches for better results.

Let Them Rest: Allow the burgers to rest for a minute before digging in to let the flavours settle.
