How to Make Sonic Double Smasher Burger: A Delicious Review and Guide
Step 1: Combine the Burger Ingredients
In a large bowl, gently combine the ground beef with Worcestershire sauce, garlic powder, onion powder, smoked paprika, black pepper, and salt. Be careful not to overmix as it can lead to tough patties.
Step 2: Form the Patties
Divide the mixture into 8 equal portions. Gently form each portion into a ball.
Step 3: Chill the Patties (Optional)
Place the formed patties on a plate or baking sheet lined with parchment paper. Cover and refrigerate for at least 30 minutes. This helps them hold their shape during cooking.
Step 4: Make the Sonic Signature Sauce
In a medium bowl, whisk together mayonnaise, ketchup, yellow mustard, sweet pickle relish, white vinegar, garlic powder, paprika, and cayenne pepper if using.
Step 5: Taste and Adjust Sauce
Taste the sauce and adjust any seasonings according to your preference.
Step 6: Chill the Sauce
Cover the bowl with plastic wrap and refrigerate for at least 30 minutes to allow flavors to meld.
Step 7: Prepare Cooking Surface
Heat your cast iron skillet or griddle over medium-high heat. Add olive oil once hot until it shimmers.
Step 8: Smash the Patties
Place four beef balls onto the hot skillet with some space between them. Immediately use a sturdy metal spatula to smash each ball down into thin patties about 1/4 inch thick.
Step 9: Sear the Patties
Cook undisturbed for 2-3 minutes until a dark brown crust forms on one side.
Step 10: Flip and Cook
Carefully flip each patty using your spatula. Cook for another minute or two until they are fully cooked through with an internal temperature of 160°F (71°C).
Step 11: Add Cheese
During the last minute of cooking time on each patty, place a slice of American cheese on top. Let it melt slightly before removing from heat.
Step 12: Repeat
Remove cooked patties from skillet and set aside. Repeat cooking process with remaining beef balls and cheese.
Step 13: Toast the Buns (Optional)
Lightly toast brioche buns either in a toaster or on your skillet until golden brown.
Step 14: Sauce the Buns
Spread a generous layer of Sonic Signature Sauce on both top and bottom buns.
Step 15: Layer the Bottom Bun
On each bottom bun layer shredded lettuce, sliced tomato, and diced onions for added crunch.
Step 16: Stack the Patties
Place two cheeseburger patties atop your vegetable layer on each bun.
Step 17: Add Pickles (Optional)
If desired, add pickle slices on top of those delicious patties for extra flavor.
Step 18: Top it Off
