cheesy, crispy feta potato rösti with caramelized onions (gluten-free, vegetarian)

Faster and more forgiving than fries and less fussy when it comes to nailing a crispy, deep golden brown, pan-fried, golden potato rösti are one of my favorite potato dishes. Although not traditional, this recipe adds briny feta and oregano into the shredded potato mixture, and is topped with a scattering of sweet caramelized onions and garlicky sour cream. If you're feeling fancy, try it topped with a poached egg!
