Our vegan cheesy potatoes are the perfect casserole for any occasion. Creamy, comforting, and packed with flavor, they're sure to be a hit with vegans and non-vegans alike.
Preheat your oven to 350°F/175°C. Grease a 9x13 pan.
Set out frozen potatoes to thaw.
In a large mixing bowl, combine the vegan cheddar cheese, vegan sour cream, vegan cream cheese, salt, pepper, onion powder, and garlic powder. Mix well to combine. If the mixture is too thick, stir in 1 to 3 tablespoons plant-based milk.
Pour in the thawed potatoes.
Stir this mixture then transfer the mixture to the prepared baking dish.
For the Potatoes Topping:
Combine cornflakes with melted vegan butter. Stir until coated.
Sprinkle cornflakes over the casserole. Bake uncovered in the preheated oven for 50 to 55 minutes, or until the top is golden brown and the potatoes are heated through.
Serve the potatoes hot. Garnish them with additional grated vegan cheese and/or chopped herbs.
Notes
Make Ahead
Assemble the casserole except for the topping. Cover it and refrigerate for 1 to 2 days. When you're ready to bake, prepare the topping, and distribute it on top of the casserole. Increase the baking time for an additional 5-10 minutes if it's coming straight from the fridge.
Thawing Potatoes
Place the frozen hash browns in the fridge the night before so they can thaw overnight.
