This recipe is a loving homage to the iconic In-N-Out Burger's Double-Double, capturing its signature flavors and fresh simplicity for your home kitchen.
**1. Prepare the Secret Spread:** In a small bowl, whisk together the mayonnaise, ketchup, sweet pickle relish, white vinegar, garlic powder, onion powder, sugar, and paprika (if using). Cover and refrigerate for at least 15 minutes to allow flavors to meld. This can be made ahead of time.
**2. Prepare the Grilled Onions:** Heat 1/2 tablespoon of oil in a small skillet over medium heat. Add the finely diced onions and cook, stirring occasionally, until softened and lightly caramelized, about 5-7 minutes. If they start to dry out, add a splash of water or broth to help them steam and soften. Remove from heat and set aside.
**3. Prepare Burger Patties:** Divide the ground chuck into 4 equal portions (about 4 oz each). On a piece of parchment paper, gently form each portion into very thin, wide patties, slightly larger than your buns, as they will shrink when cooked. Season generously with salt and freshly ground black pepper on both sides.
**4. Prepare Toppings:** Slice the tomato and thinly slice the remaining raw onion (if using). Shred or tear the iceberg lettuce.
**5. Toast Buns:** Heat a large cast-iron skillet or griddle over medium-low heat. If desired, lightly butter the cut sides of the buns. Place the buns cut-side down on the skillet and toast until golden brown, about 1-2 minutes. Remove and set aside.
**6. Cook Burgers:** Increase the heat of the skillet to medium-high. Add the remaining 1/2 tablespoon of oil. Once shimmering, add the burger patties, being careful not to overcrowd the pan (cook in batches if necessary). Cook for 2-3 minutes per side for a medium-rare to medium doneness, pressing down lightly with a spatula to ensure a good sear.
**7. Melt the Cheese:** During the last minute of cooking, place one slice of American cheese on top of each patty. If cooking a double cheeseburger, place two patties side-by-side and then top with two slices of cheese. Cover the skillet with a lid or a metal bowl for 30-60 seconds to help the cheese melt perfectly.
**8. Assemble the Burgers:** To assemble each Double-Double, spread a generous amount of secret spread on both the top and bottom toasted bun halves. On the bottom bun, layer shredded lettuce, tomato slices, and then place one cheeseburger patty. Top with some grilled onions and raw onion slices (if using), then add the second cheeseburger patty. Finish with another dollop of spread on the top patty, then cover with the top bun.
**9. Serve Immediately:** Enjoy your homemade In-N-Out style Double-Double right away!
