Mix half a 28-ounce bag frozen thick-cut hash browns with 2 beaten eggs, 1/2 grated onion, 1/3 cup chopped dill, 2 sliced scallions and 2 tablespoons flour; season with 1 teaspoon kosher salt and a few grinds of pepper. Heat 1/4 cup vegetable oil in a large nonstick skillet over medium-high heat. Scoop 1/3 cup mounds of the potato mixture into the skillet and gently flatten with a spatula. Cook until browned, 2 to 3 minutes per side, adjusting the heat as necessary. Sprinkle with salt. Repeat, adding more oil as needed.
