EACH White Castle slider is steam-grilled over savory onions to create the hot, tasty flavor you crave. Our burgers are made from 100% beef, with zero additives or fillers. After just a few seconds in the microwave or a few minutes on the stove top, America's favorite slider is ready to eat.

Keep frozen. Heating Instructions: For best results - fully thaw in refrigerator and use promptly. Do not refreeze. Microwave (1200-Watt): 1. Open one end of package. 2. Separate sandwiches inside package. 3. Microwave on high 60 seconds if frozen/35 seconds if thawed. Microwave wattages may vary requiring slight adjustments to heating times. For food safety and quality, heat to a minimum internal temperature of 165 degrees F (74 degrees C). Stove Top (For Steaming of Burgers): 1. Cover bottom of a medium saucepan with water. Keep water below bottom of steamer insert. Cover and bring to a boil. 2. Cover insert with foil just large enough to hold sandwiches so bun heels don't come in contact with insert. 3. Place individual sandwiches on top of foil, insert into the pan. Cover/reduce heat to low. 4. Steam 10-12 minutes if frozen, 8-10 minutes if thawed, or until center of sandwiches reach 165 degrees F (74 degrees C). 5. Remove burgers from pan using a spatula. Note: Bun tops may be wrinkled, but very soft like fresh from our restaurants. For additional heating instructions, please refer to our website. Serving Suggestion: Add pickles and your favorite condiments.
