Almost White Castle Hamburgers

Ingredients

• 1.5 pounds ground chuck
• 0.33 cups plain bread crumbs
• 1 large egg
• 1 package dry onion soup mix , 1 ounce
• 2 tablespoons water
• 0.5 teaspoons ground black pepper
• 24 small square dinner rolls

Instructions

1. 1

   Preheat the oven to 400 degrees F (200 degrees C).

2. 2

   Combine ground chuck, bread crumbs, egg, onion soup mix, water, and black pepper in a bowl; press into a 10x15-inch jelly roll pan. Prick holes through the chuck mixture for ventilation while cooking.

   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.
