Preheat the oven to 400°F (200°C) and line a large rimmed half-sheet baking pan with parchment paper.
Place the thawed shredded hash browns in a large bowl.
In a small bowl, whisk the eggs until combined, then pour them over the potatoes.
Add the shredded cheddar, salt, ground cumin, dried thyme, and garlic powder to the bowl and toss until evenly coated.
Pour the melted butter over the potato mixture and toss again to distribute the butter evenly.
Spread the mixture evenly across the prepared baking sheet in a single layer and smooth the top.
Bake for about 40 minutes, until the top is golden and the edges are crisp.
Remove from the oven, cut into 12 pieces, and serve warm.
