Ingredients

Scale

Hash Brown Base

  • 8 frozen hash brown patties

Special Sauce

  • 1 onion (grated and diced), use 2 tablespoons finely grated for sauce
  • 1 cup mayonnaise
  • 2 teaspoons kosher salt, divided
  • 2 tablespoons sweet pickle relish
  • 2 teaspoons white vinegar
  • 2 teaspoons sugar
  • 2 teaspoons mustard
  • 1 1/2 teaspoons paprika
  • 1 teaspoon onion powder

Beef Mixture

  • 1 tablespoon olive oil
  • 1 1/4 lb ground beef sirloin
  • 1 teaspoon freshly ground black pepper
  • 2 teaspoons Worcestershire sauce
  • 1 onion (diced, remainder after 2 tablespoons grated)
  • 8 ounces Cheddar cheese, grated (divided into 1 1/3 cups and remainder)
  • 2 teaspoons sesame seeds

Toppings

  • 3 cups shredded iceberg lettuce
  • ½ cup hamburger dill pickle slices, roughly chopped

Instructions

  1. Preheat and Prep: Preheat your oven to 400°F (200°C). Arrange the frozen hash brown patties in a single layer on the bottom of a 9×13 baking dish. Bake until the bottoms are golden and crispy, approximately 25 minutes.
  2. Make the Special Sauce: While the hash browns bake, finely grate 2 tablespoons of onion and mix it with mayonnaise, ½ teaspoon kosher salt, sweet pickle relish, white vinegar, sugar, mustard, paprika, and onion powder. This creates the creamy and tangy Big Mac-style sauce. Set aside.
  3. Cook the Beef: Heat olive oil in a large skillet over medium-high heat. Add ground beef and cook undisturbed for 3 minutes, then crumble with a spoon and continue cooking for about 5 minutes until fully browned. Stir in remaining 1 ½ teaspoons kosher salt, black pepper, Worcestershire sauce, and the diced onion. Cook for an additional minute to combine flavors.
  4. Assemble the Casserole: Remove skillet from heat. Stir 2/3 cup of the special sauce and 1 1/3 cups of shredded Cheddar cheese into the beef mixture until well combined. Flip the baked hash browns so the crispy side is facing up. Spoon the beef mixture evenly over the hash browns, then sprinkle with the remaining cheese and sesame seeds.
  5. Bake Again: Return casserole to the oven and bake for 10–12 minutes, or until the cheese melts fully and becomes bubbly. Once done, remove and let it stand for 5 minutes to set.
  6. Final Touches: Top the baked casserole with shredded iceberg lettuce, drizzle with the remaining special sauce, and scatter the chopped dill pickle slices over the top. Serve immediately to enjoy the freshest texture and maximum flavor impact.

Notes

  • For extra crispiness, ensure hash browns are baked until golden before assembling.
  • The special sauce can be made ahead and refrigerated to deepen the flavors.
  • Ground sirloin is preferred for the beef mixture due to its balance of flavor and leanness.
  • Adjust seasoning to taste, especially salt and pepper, to suit preferences.
  • Leftovers can be refrigerated and reheated in the oven for best texture retention.
