Tips & Substitutions
For a juicier texture, consider adding a tablespoon of Worcestershire sauce to the meat mixture. You can substitute ground turkey or chicken for a lighter option. If you don't have onion soup mix, finely chopped onions and garlic powder can be used instead. This recipe can also be adapted to make sliders by using smaller squares.
Serving Suggestions
Serve these White Castles as a fun appetizer or party snack. They pair beautifully with classic American recipes like Quick Homemade Chili or a fresh side salad. Consider adding toppings like pickles, mustard, or cheese for extra flavor. For a complete meal, serve alongside potato wedges or coleslaw.

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the squares in a microwave-safe dish and cover with a damp paper towel to retain moisture. Heat in 30-second intervals until warmed through, or reheat in a 350°F oven for about 10 minutes to maintain texture.
