Ingredients You Need
Making Potato O’Brien doesn’t require complicated ingredients. Most versions rely on pantry staples that you may already have in your kitchen.
Here’s a classic ingredient list:
- 4 medium potatoes, diced into cubes
- 1 red bell pepper, chopped
- 1 green bell pepper, chopped
- 1 small onion, diced
- 2 tablespoons olive oil

Choosing fresh vegetables makes a noticeable difference. Bright peppers and firm potatoes help give the dish its signature color and texture.
Step-by-Step Guide to Making Potato O’Brien
Preparing Potato O’Brien is straightforward, but following the right steps helps you achieve the perfect balance between softness and crispiness.
Step 1: Prepare the Potatoes
Wash and dice the potatoes into small cubes. Try to keep the pieces uniform so they cook evenly.
Some cooks prefer to parboil the potatoes briefly before cooking. This helps the inside become tender while allowing the outside to crisp beautifully.
Step 2: Chop the Vegetables
Dice the onion and bell peppers into small pieces. The goal is to distribute them evenly throughout the dish so every bite includes a mix of flavors.
Step 3: Heat the Oil
Place a large skillet over medium heat and add olive oil. Allow the oil to warm before adding the potatoes.
Step 4: Cook the Potatoes
Add the diced potatoes and let them cook undisturbed for a few minutes. This helps create a golden crust that gives Potato O’Brien its classic texture.

Step 5: Add Peppers and Onions
Once the potatoes begin to soften, stir in the peppers and onions. Continue cooking until the vegetables become tender and slightly caramelized.
Step 6: Season and Finish
Season with salt, pepper, and paprika if desired. Stir gently and cook for another minute before serving.

Oven Method for Potato O’Brien
If you prefer a more hands-off approach, you can bake Potato O’Brien instead of frying it.
Preheat your oven to 375°F (190°C). Spread the diced potatoes, peppers, and onions on a baking sheet. Drizzle with oil and season well. Roast for about 30–35 minutes, stirring halfway through to ensure even cooking.
This method produces a slightly softer texture while still delivering delicious flavor.
Tips for Perfect Texture and Flavor
Cooking Potato O’Brien successfully comes down to a few simple techniques.
Use the Right Heat
Medium heat allows the potatoes to cook through without burning the vegetables.
Avoid Overcrowding
Too many ingredients in one pan can trap moisture and prevent crispiness.
Dry the Potatoes
If you rinse them, pat them dry before cooking to help achieve a golden surface.
Season Gradually
Adding seasoning at different stages helps build flavor without overwhelming the dish.
Creative Variations to Try
One of the best things about Potato O’Brien is how easily you can customize it.
Cheesy Version
Sprinkle shredded cheese over the potatoes just before serving for a creamy finish.
Spicy Style
Add chili flakes or smoked paprika for extra warmth.
Herb-Infused
Fresh parsley, thyme, or rosemary can add brightness and aroma.
Protein Addition
Diced chicken or turkey sausage can transform Potato O’Brien into a complete meal.
These variations allow you to enjoy the classic recipe while adding your personal touch.
Serving Ideas
Potato O’Brien pairs beautifully with many dishes. Here are some serving suggestions:
- Scrambled or fried eggs
- Toast or breakfast wraps
- Grilled chicken or steak
- Fresh salads
- Roasted vegetables
Because the flavors are mild yet savory, this dish complements both hearty and light meals.
Is Potato O’Brien Healthy?
While potatoes are often seen as comfort food, they also provide important nutrients like potassium and fiber. The addition of peppers and onions brings vitamins and antioxidants, making Potato O’Brien more balanced than plain fried potatoes.
To create a lighter version, consider baking the ingredients instead of frying them. Using olive oil and adding extra vegetables can also make the dish feel more nutritious while still maintaining its classic flavor.
Storage and Reheating Tips
If you have leftovers, Potato O’Brien stores well and can be enjoyed later.
- Refrigerate in an airtight container for up to three days.
- Freeze portions for longer storage.
- Reheat in a skillet to bring back the crispy texture.
Avoid reheating for too long in the microwave, as it may soften the potatoes.
