Crispy hash browns made with cheese in a cast iron skillet
Combine the shredded potatoes, onion, shredded cheddar cheese, garlic powder, rosemary, salt, and pepper to a large bowl. Mix until thoroughly combined.
Heat the olive oil and butter in a large cast iron skillet over medium heat until the butter has fully melted. Carefully swirl the skillet to evenly coat the bottom.
Add the potatoes to the skillet in four separate “patties.” Cook until golden brown on the bottom, approximately 4-5 minutes before flipping. Cook for another 4-5 minutes, or until golden brown and crispy on both sides. Work in batches if you need to (depending on the size of your skillet.) Add more olive oil as needed.
Remove from heat and transfer the hash browns to individual plates. Serve with eggs, fruit, meat, etc. Enjoy!
