Preheat the oven to 350 degrees F. Line a baking sheet with nonstick aluminum foil.
Break the frozen patties apart and place on the prepared baking sheet. Divide the brown sugar evenly over each patty. Sprinkle with nutmeg, cinnamon sugar, lemon zest, a pinch of salt and a grind or two of black pepper. Bake until golden around the edges, 20 to 25 minutes. Serve with a spritz of lemon juice.
