Step 1

Preheat the oven to 400 degrees F.

Step 2

Scatter the hash browns in a 9-by-13-inch baking dish. Pinch off pieces of ground beef and scatter on top of the potatoes. Top with the diced tomatoes and green chiles, taco seasoning and scallion whites. Scatter the processed cheese cubes over top. Bake until the ground beef is cooked through, about 45 minutes.

Step 3

Remove from the oven and stir until well combined. Top with the Cheddar and bake until the cheese is melted and bubbling in some places, about 15 minutes.

Step 4

Let cool for 10 minutes, then top with the scallion greens, sour cream, guacamole, pickled jalapeños and cilantro leaves.
