Instructions

1. 1

   Gather all ingredients. Preheat the oven to 400 degrees F (200 degrees F).

2. 2

   Place hash brown patties in a single layer along the bottom of a 9x13 baking dish. Bake in the preheated oven until golden and crisp on the bottom, about 25 minutes.

3. 3

   Meanwhile, grate or very finely mince 2 tablespoons of onion and set aside, along with any accumulated juices. Cut the remaining onion into asmall dice and set aside.

4. 4

   While hash browns bake, combine grated onion with mayonnaise, 1/2 teaspoon salt, sweet pickle relish, white vinegar, sugar, mustard, paprika, and onion powder in a bowl and mix well. Set aside.

5. 5

   Heat oil in a large skillet over medium-high heat. Add beef and cook, undisturbed for 3 minutes. Continue to cook, while crumbling the meat with the back of a spoon and stirring occasionally, until browned and mostly cooked through, about 5 minutes. Season with remaining salt, pepper, Worcestershire and remaining chopped onions and cook for 1 minute.

6. 6

   Remove from the heat and stir in 2/3 cup of the sauce mixture and 1 1/3 cup cheese.

7. 7

   Flip hashbrown patties over so the crispy side is on top. Pour meat mixture over hash browns and top with remaining shredded cheese.

8. 8

   Sprinkle with sesame seeds and bake until bubbly and cheese is melted, 10 to 12 minutes. Remove from oven and let stand for 5 minutes.

9. 9

   Top with shredded lettuce and drizzle with remaining sauce. Top with chopped pickles and serve immediately.
