As much as I like to cook dishes from scratch, I discovered that the key ingredient here is frozen shredded hash brown potatoes. Frozen hash browns are par-cooked before they’re frozen, and the freezing process helps release some moisture in the potatoes and allows them to crisp up nicely. Par-cooking also cuts down on cooking time — always a plus when I’m bleary-eyed in the morning. Freshly grated potatoes would have to go through a rigorous process of squeezing out moisture and pre-cooking to get the same results, so frozen is the name of the game here.
