How to Cook Frozen Potatoes O’Brien in the Oven

Potatoes O’Brien is a classic American dish that combines diced potatoes, onions, and peppers, creating a flavorful and versatile side dish. While it’s commonly prepared using fresh ingredients, frozen Potatoes O’Brien offer a convenient alternative that saves time without compromising on taste. In this article, we will guide you through the steps to cook frozen Potatoes O’Brien in the oven, ensuring a crispy and delicious outcome.

– 1 bag of frozen Potatoes O’Brien
– 2 tablespoons of olive oil

1. Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper or aluminum foil.
2. Spread the frozen Potatoes O’Brien evenly on the prepared baking sheet. Make sure they are not overcrowded to allow for proper browning.
3. Drizzle the olive oil over the potatoes, ensuring each piece is coated. This will help them crisp up in the oven.

5. Place the baking sheet in the preheated oven and bake for 20-25 minutes, or until the potatoes are golden brown and crispy. Flip them halfway through the cooking time to ensure even browning.
