Potatoes are a dinner staple. They are cheap. They are filling. They go with almost everything. But not all potato recipes are created equal. Some take forever. Some require constant attention. Some produce soggy, disappointing results.
These 5-Ingredient Oven White Potato Halves are the opposite. Small to medium white potatoes. Olive oil. Salt. Pepper. Garlic powder. That is it. You toss the potato halves in seasoned oil. You arrange them cut-side down on a hot baking sheet. You roast. The result is potatoes with a deeply golden, crispy, almost crunchy exterior and a creamy, fluffy interior. The garlic powder adds savory depth. The salt and pepper do their essential work.
This is the side dish you will make on repeat. It is simple enough for a Tuesday. It is impressive enough for company. It is the kind of recipe that becomes second nature.
Let me show you how to make them.

Ingredients
Servings: 4
-

-
3 tablespoons olive oil
-
1 teaspoon kosher salt, plus more to taste
-
1/2 teaspoon freshly ground black pepper
-
1 teaspoon garlic powder
Ingredient Notes
White potatoes: Use small to medium white potatoes. They have thin skins and a creamy, waxy texture that holds up well during roasting. Look for potatoes about 1 to 2 inches in diameter. If your potatoes are larger, cut them into quarters instead of halves. Do not use russet potatoes, which are too starchy and can become mealy.
Olive oil: Olive oil adds richness and helps the potatoes brown and crisp. It also carries the seasonings. Avocado oil or vegetable oil can be substituted. Do not use butter, which can burn at 425°F.
Kosher salt: Kosher salt has larger crystals that dissolve more slowly and season more evenly. If using table salt, reduce to 3/4 teaspoon.
Freshly ground black pepper: Freshly ground pepper has more flavor than pre-ground. The pepper adds warmth and a little kick.
Garlic powder: Garlic powder distributes evenly and adds savory depth without the risk of burning that comes with fresh garlic. Do not use garlic salt, which would add unnecessary sodium.
Step-by-Step Instructions
Step 1: Preheat the Oven and Baking Sheet
Preheat your oven to 425°F (220°C). Place a metal baking sheet or roasting pan on the middle rack while the oven heats. The pan needs to be hot when the potatoes hit it. This jump-starts the browning process.
Step 2: Prepare the Potatoes
Scrub the white potatoes well under cool running water. Remove any dirt or blemishes. Pat them completely dry with a clean kitchen towel. Moisture is the enemy of crispiness. Leave the skins on for extra texture and flavor. Cut each potato in half lengthwise.
Step 3: Make the Seasoned Oil
In a large bowl, combine the olive oil, kosher salt, black pepper, and garlic powder. Stir to make a simple, well-seasoned oil mixture.
Step 4: Toss the Potatoes
Add the potato halves to the bowl. Toss thoroughly until every cut side and skin is lightly coated with the seasoned oil. This helps the potatoes brown and keeps them from sticking.
Step 5: Arrange on the Hot Pan
Carefully remove the hot baking sheet or roasting pan from the oven. Place it on a heat-safe surface. Quickly arrange the potato halves cut-side down in a single layer. Make sure they are not overlapping so they roast instead of steam.
Step 6: Roast
Return the pan to the oven. Roast for 25 to 30 minutes, without flipping, until the cut sides are deep golden brown and the potatoes are tender when pierced with a fork. A knife should slide into the center with no resistance.
Step 7: Serve
Remove the pan from the oven. Let the potatoes rest for 2 to 3 minutes. Transfer to a serving platter. Sprinkle with a little more salt if desired. Serve hot.

Pro Tips for Absolute Success
Preheat the baking sheet. A hot pan is essential for crispy bottoms. Do not skip this step.
Dry the potatoes thoroughly. Any moisture on the surface will create steam, which prevents browning. Pat them completely dry.
Do not overcrowd the pan. Overcrowding traps steam and makes the potatoes soggy. Use a large pan. Leave space between each potato half.
Arrange cut-side down. The cut side should be in direct contact with the hot pan. This creates the crispy, golden crust.
Do not flip the potatoes. Flipping is unnecessary. The cut side will crisp beautifully. The skin side will soften.
Use a metal baking sheet. Metal conducts heat better than glass. A metal pan produces crispier potatoes.
Cut potatoes to similar sizes. Uniform pieces cook evenly. If your potatoes vary in size, cut larger ones into quarters.
Frequently Asked Questions
Can I use red potatoes instead of white?
Yes. Red potatoes have a similar texture and work beautifully. Yukon Gold potatoes are also excellent.
Can I use russet potatoes?
Russet potatoes are not recommended for this recipe. They are starchier and can become mealy. They also have thicker skins that may not crisp as well.
Can I use melted butter instead of olive oil?
Yes. Butter will add richness but can burn at 425°F. Use clarified butter or ghee for a higher smoke point.
Why are my potatoes not crispy?
Your pan was not hot enough, the potatoes were not dry, or the pan was overcrowded. Preheat the pan thoroughly. Pat the potatoes dry. Use a larger pan.
Can I add other seasonings?
Yes. Rosemary, thyme, paprika, onion powder, and cayenne all work well. Add them to the oil mixture.
Can I roast other vegetables alongside the potatoes?
Yes. Carrots, parsnips, or Brussels sprouts can be added. Cut them to similar sizes. Arrange them in a single layer.
Can I make these ahead of time?
These potatoes are best fresh from the oven. The crispy exterior softens as they cool. If you need to make them ahead, reheat in a 425°F oven for 5 to 10 minutes to re-crisp.
How do I reheat leftovers?
Reheat in a 425°F oven for 5 to 7 minutes. The microwave will make them soft.
Can I freeze roasted potatoes?
Freezing is not recommended. The texture of roasted potatoes degrades upon thawing. They become mealy and watery.
Why do I need to preheat the pan?
A hot pan creates immediate browning when the potatoes make contact. This jump-starts the Maillard reaction, which creates flavor and crispiness. A cold pan will produce pale, soft potatoes.
The Beauty of Simple Roasted Potatoes
Roasted potatoes are one of the simplest dishes in the culinary canon. But simplicity does not mean easy. It means stripped down to essentials. It means every element matters.
The cut-side-down method is the secret. Most roasted potato recipes tell you to toss the potatoes in oil and spread them out cut-side up. The cut side dries out. The skin side browns unevenly. The result is fine but not great.
This recipe flips that. The cut side goes directly against the hot pan. The heat sears the exposed flesh, creating a deep golden crust. The skin side softens and blisters. The interior becomes fluffy and creamy. It is a small change that makes a huge difference.
These potatoes are not trying to be fancy. They are trying to be good. And they succeed.
Keep white potatoes in your pantry. Keep olive oil, salt, pepper, and garlic powder in your kitchen. This recipe is the reason why.
