Oven Roasted Potatoes O’Brien

If you like fried potatoes but not the constant stirring at the stove, Oven Roasted Potatoes O’Brien are the answer! Everything cooks in a hot skillet in the oven, so the potatoes roast instead of fry while you get on with the rest of the meal. It’s an easy way to get that classic diner-style potato side without standing over a pan.

Potatoes O’Brien have a simple, classic flavor built from potatoes, onions, and sweet peppers. As they roast, the potatoes become crisp on the outside with a fluffy center. The result is classic potatoes O’brien flavor that pairs well with almost anything.

This is one of those sides that works any time of day too. It’s great next to eggs or breakfast sandwiches in the morning, but it also fits right in beside chicken, steak, or pork at dinner. Because everything roasts together, it’s an easy dish to start and let the oven handle.

What You Need To Make Oven Roasted Potatoes
The ingredients are simple and easy to keep on hand. Waxy potatoes work especially well because they hold their shape when stirred and roasted.
- cooking oil
- waxy yellow potatoes
- onion
- bell pepper
- salt
- garlic powder
- onion powder
- black pepper
If russet potatoes are what you have, they’ll still work in this recipe. Waxy potatoes like yellow or red varieties hold together better when stirred and roasted, so they tend to keep their neat diced shape. Russets tend to be softer and may break apart a little more, but they will still roast nicely and taste great.
Add more or less chopped peppers or onions to this recipe, make it yours! Same with the salt, pepper, onion powder and garlic powder, you can add more or less of all those. Taste them at the halfway point of roasting and adjust the seasonings then.

Got Leftovers?
If you happen to have leftovers, store them well covered in the refrigerator. They will keep for up to three days.
Reheat them in the air fryer for best results, they’ll come out nice and crispy! But a skillet on the stove top or in the oven works fine too. The microwave works, but the potatoes will be softer.
