Almost White Castle Hamburgers

Ingredients

Original recipe (1X) yields 24 servings

• 1 ½ pounds ground chuck
• ⅓ cup plain bread crumbs
• 1 large egg
• 1 (1 ounce) package dry onion soup mix
• 2 tablespoons water
• ½ teaspoon ground black pepper
• 24 small square dinner rolls

Directions

1. Preheat the oven to 400 degrees F (200 degrees C).
2. Combine ground chuck, bread crumbs, egg, onion soup mix, water, and black pepper in a bowl; press into a 10×15-inch jelly roll pan. Prick holes through the chuck mixture for ventilation while cooking.
3. Bake in the preheated oven until browned and cooked through, about 10 minutes. An instant-read thermometer inserted into the center should read at least 160 degrees F (70 degrees C). Drain excess grease.
4. Cut chuck mixture into squares the size of the rolls. Place 1 chuck patty in each roll.
