Recipes for Sonic food include CopyKat's Sonic onion ring recipe and Top Secret Recipes' Sonic drive-in signature burger recipes. Top Secret Recipes' offers recipes for the all-American Sonic Burger, the smoky Hickory Burger and the spicy Jalapeño Burger.
To make CopyKat's Sonic onion rings, dip some sliced and separated Spanish onions in a bowl of water, then place them in a bowl of all-purpose flour. Shake off the excess flour and dip the onions in melted vanilla ice milk. Then, place the onions in a bowl of corn meal. Place the onions on a cookie sheet and wait for them to air dry, typically at least 20 minutes. Fry the dried onions until they turn brown.
To make Top Secret Recipe's all-American Sonic Burger, shape 1/4 pound of ground beef into a patty about the size of the bun. Preheat a skillet over medium heat. Spray the two halves of the bun with butter spray. Heat the buns on the skillet until they turn light brown. Fry the patty in a hot pan and season it with salt and ground black pepper. Each side of the patty takes three to four minutes to cook. While the patty cooks, spread 2 teaspoons of mayonnaise over the bottom bun. Place some pickle slices on the mayonnaise and sprinkle with chopped onion. Place some lettuce, tomato slices and the cooked patty on the onion. Cover the sandwich with the top piece of the bun.
