Homemade fries from raw potatoes get crispy in the oven with a few key preparation steps. If you want to know how to make fries from potatoes in the oven, the secret is simple: cut them evenly, soak them, dry them well, and use a hot oven with a little oil. This guide walks you through every stage so your fries come out golden, not soggy.
Why Oven Fries Beat Store-Bought Ones
Oven fries use way less oil than deep frying. You control the salt, the seasoning, and the thickness. They also cost less per serving, since a bag of potatoes goes a long way.
The main challenge is getting them crisp. A wet potato steams instead of roasts. Fix that and you get fries that rival any restaurant.
What You Need Before You Start
Ingredients
- 2 pounds of russet or Yukon Gold potatoes
- 2 to 3 tablespoons of olive oil or avocado oil
- 1 teaspoon of salt, plus more for finishing
- Half a teaspoon of black pepper
- Optional: garlic powder, paprika, or rosemary
Tools
- A sharp chef’s knife or a mandoline
- A large bowl for soaking
- Clean kitchen towels or paper towels
- A rimmed baking sheet
- Parchment paper or a wire rack
How To Make Fries From Potatoes In The Oven
Follow these steps in order. Rushing any stage usually leads to pale, limp fries.
Step 1: Pick The Right Potato
Russets are the best choice. They have a high starch content, which means a fluffy inside and a crisp outside. Yukon Golds work too, but they come out a bit creamier. Waxy potatoes like reds tend to stay firm and never get that classic fry texture.
Step 2: Wash, Peel, And Cut
Scrub the potatoes under cold water. You can leave the skin on for extra texture, or peel them if you prefer. Cut each potato into sticks about a quarter inch thick. Try to keep every stick the same size, because uneven pieces cook at different speeds.
A mandoline makes this fast, but a sharp knife works fine. Just watch your fingers.
Step 3: Soak The Cut Fries
Put the cut fries in a big bowl of cold water. Let them sit for at least 30 minutes. An hour is even better.
Soaking pulls starch out of the surface. Less surface starch means the fries don’t stick together and they brown more evenly. If you skip this step, expect clumps and soft spots.
Step 4: Dry Them Completely
Drain the fries in a colander. Then spread them on a clean towel and pat them dry. Really dry. Any water left on the surface will turn into steam in the oven, and steam is the enemy of crispiness.
Let them air dry for 10 more minutes if you have the time.
Step 5: Season And Oil
Move the dry fries to a dry bowl. Drizzle with oil and toss until every piece is lightly coated. Add the salt, pepper, and any spices you like.
Don’t drown them. Too much oil makes them greasy instead of crisp. Two tablespoons is usually enough for two pounds of potatoes.
Step 6: Heat The Oven And Pan
Preheat your oven to 425 degrees Fahrenheit. Place the baking sheet inside while it heats. A hot pan gives the bottom of each fry a head start on browning.
Line the hot sheet with parchment paper, or use a wire rack set on the sheet for airflow.
Step 7: Arrange In A Single Layer
Spread the fries on the pan in one layer. Leave space between them. If they touch, they steam each other and turn soft. Use two pans if you need to.
Step 8: Bake And Flip
Bake for 20 minutes. Pull the pan out and flip each fry with a spatula or tongs. Return the pan and bake for another 15 to 20 minutes, until the edges are golden brown.
Ovens vary, so start checking at the 30 minute mark.
Step 9: Salt Right Away
Move the hot fries to a bowl or plate. Sprinkle a little more salt while they’re still hot. Salt sticks better to hot food, and it soaks in instead of falling to the bottom.
Tips For Extra Crispy Oven Fries
- Parboil the cut fries for 3 minutes, then dry and roast. This softens the inside so the outside can crisp faster.
- Add a tablespoon of cornstarch to the oil toss. It creates a thin coating that browns beautifully.
- Use a wire rack. Air circulates under the fries and you don’t have to flip them.
- Keep the oven door closed. Every time you open it, heat escapes and cooking slows down.
- Cut thinner fries for more crunch. Thick wedges stay softer in the middle.
Common Mistakes To Avoid
- Not soaking the potatoes. This is the number one reason oven fries turn out soggy.
- Crowding the pan. Overlap equals steam, and steam equals mush.
- Using too much oil. A light coat is all you need.
- Skipping the preheat. A cold oven gives you pale, tough fries.
- Cutting uneven sizes. Small pieces burn before large ones cook through.
Serving And Storage
Serve your fries right away. They taste best within 15 minutes of leaving the oven. Pair them with ketchup, aioli, or a simple garlic yogurt dip.
If you have leftovers, store them in the fridge for up to three days. Reheat them in the oven or an air fryer at 400 degrees for about 5 minutes. The microwave will make them soft, so avoid it if you can.
Final Thoughts
Making fries from raw potatoes in the oven comes down to a few habits: soak, dry, oil lightly, and give them room to breathe. Once you nail these steps, you can season them any way you like and still get a crisp result every time. Start with russets, keep your cuts even, and let the hot oven do the rest.
