Quick Takeaway
Potatoes are normally High in oxalates, and the skin contains the greatest concentration. For these home fries, I peel the potatoes completely, cut them into 1/2-inch cubes, and boil them in plenty of water for a full 8 minutes. Peeling removes the higher-oxalate skin, and boiling lets some soluble oxalates move into the water before you drain and discard it. After the cubes steam-dry, duck fat helps them develop extra-crisp, browned edges in the skillet.
Home fries sound simple, but two small details make the biggest difference: what you do before the skillet and how often you touch the potatoes once they are in it.
This version starts with the preparation I use when potatoes are on the menu. Peel them, boil the cubes in plenty of water, discard that water, and dry the potatoes well. Then let the duck fat and the hot skillet do the browning.
Why You’ll Love This Recipe
- The oxalate-conscious steps are built in. The potatoes are fully peeled and boiled for a full 8 minutes before frying.
- The edges get properly browned. Steam-drying removes surface moisture, and duck fat helps the cubes develop extra-crisp edges.
- The method is easy to follow. Even 1/2-inch cubes, one uncrowded layer, and the first 5 minutes undisturbed take out most of the guesswork.
- They work beyond breakfast. Serve these home fries with eggs in the morning or as a simple side dish later in the day.
Why This Method Works for Potatoes
Most of the oxalates are concentrated in and near the skin. Peeling removes the skin before cooking. Boiling the peeled cubes in plenty of water gives some soluble oxalates a way to move out of the potatoes. Draining and discarding that water removes more before the potatoes ever reach the duck fat.
The full 8-minute boil is deliberate. Start the timer after the water reaches a controlled, gentle boil. You want the outside of a cube to feel tender while the center still offers slight resistance. The cube should hold its shape when you lift it from the water.

Ingredient Notes
- White potatoes. Use evenly sized potatoes and peel every bit of skin. Cut the flesh into even 1/2-inch cubes so the pieces boil and brown at the same rate.
- Duck fat. This is the primary skillet fat and the ingredient that helps the home fries develop extra-crisp, browned edges. Duck fat is available in the Pantry.
- Sea salt, garlic powder, and white pepper. These are verified in the Low Oxalate Foods List or Food Look-Up. Add them during the last 2 to 3 minutes so the garlic powder does not scorch.

Ingredients
- 1 1/2 lbs. white potatoes, peeled and cubed
- 3 tbsp. duck fat
- 1 tsp. sea salt
- 1 tsp. garlic powder
- 1/4 tsp. white pepper
Instructions
- Peel the potatoes completely, then cut them into even 1/2-inch cubes.
- Put the potato cubes in a large pot and add enough water to cover them by at least 3 inches. Bring the water to a boil over high heat, then reduce the heat enough to maintain a controlled, gentle boil. Start the timer once the water is boiling and cook the potatoes for a full 8 minutes. At 8 minutes, the outside of a cube should be tender while the center still offers slight resistance and the cube holds its shape.
- Drain the potatoes completely and discard the cooking water. Let the cubes steam-dry in the colander for 5 to 10 minutes. Blot away any surface moisture if needed. The drier the potatoes are, the better the crispier they will turn out.
- Heat a 12-inch cast-iron or other heavy skillet over medium to medium-high heat. Add the duck fat and let it melt until it shimmers but does not smoke.
- Add the potatoes in a single layer. If they do not fit without crowding, cook them in two batches. Leave them undisturbed for about 5 minutes, then turn them in sections. Continue cooking for 8 to 10 minutes, turning only as needed, until the potatoes are browned and crisp. Reduce the heat to medium if the outside is browning before the centers finish.
- During the final 2 to 3 minutes, sprinkle the potatoes with the sea salt, garlic powder, and white pepper. Turn gently to coat without breaking the cubes. Taste and adjust the salt.
- Serve right away while the edges are crisp.
Step-by-Step Instructions
- Peel and cut. Peel the potatoes completely and cut them into even 1/2-inch cubes.
- Boil for a full 8 minutes. Place the potato cubes in a pot and cover them with 3 inches of water. Bring the water to a boil, reduce the heat to a controlled, gentle boil, and start the timer. At 8 minutes, the outside should be tender and the center should still offer slight resistance.
- Drain and dry thoroughly. Drain completely and discard the cooking water. Let the potatoes steam-dry for 5 to 10 minutes, then blot away any remaining moisture. The drier the potatoes are, the better they will brown and the crispier they will become.
- Heat the duck fat. Melt it in a 12-inch heavy skillet over medium to medium-high heat until it shimmers but does not smoke.
- Brown the first side. Add the potatoes in one uncrowded layer and leave them undisturbed for about 5 minutes.
- Finish the home fries. Turn the potatoes in sections and cook for another 8 to 10 minutes, turning only as needed. Add the sea salt, garlic powder, and white pepper during the final 2 to 3 minutes.
Pro Tips for Crisp Home Fries
- Keep the cubes even. A mix of tiny and large pieces will not finish at the same time.
- Count the 8 minutes after boiling begins. Use a controlled, gentle boil so the outside becomes tender without the cubes breaking apart.
- Dry the potatoes thoroughly. The drier the potatoes are before they enter the skillet, the better they will brown and the crispier they will become. Let them steam-dry for 5 to 10 minutes, then blot away any remaining moisture.
- Give the potatoes room. Use two batches if needed. Crowded potatoes steam instead of brown.
- Leave the first side alone. Five undisturbed minutes gives the skillet time to build a browned crust.
- Watch your skillet. Heavy skillets hold heat well. Reduce the heat to medium if the edges brown before the centers finish.
Storage and Reheating
- Refrigerator. Let leftovers cool, then store them in a covered container for up to 4 days.
- Skillet reheating. Warm a small amount of duck fat over medium heat and reheat the potatoes in one layer until hot and crisp.
- Air fryer reheating. Reheat in a single layer until hot, checking early so the edges do not become too dark.
Substitutions and Variations
- Add fresh chives after cooking. Chives are Low in the Food Look-Up and give the finished home fries a mild onion flavor.
- Add a little rosemary near the end. Rosemary is Low in the Food Look-Up. Mince it finely and use a small amount so it does not take over the potatoes.
- Use duck fat, or substitute ghee. Both fats tolerate the higher cooking temperatures needed for crisp, golden-brown potatoes without burning as quickly as regular butter. Duck fat adds a rich, savory flavor, while ghee gives the home fries a milder, buttery taste.
Frequently Asked Questions
Are these home fries low oxalate?
This method removes the skin and lets some soluble oxalates move into the boiling water before that water is discarded.
Why do you peel potatoes for this recipe?
The skin contains the highest concentration of oxalates. Peeling removes that outer portion before the potatoes go into the water.
Why do the potatoes boil for a full 8 minutes?
Allie chose the full 8 minutes so the peeled cubes spend enough time in plenty of water before frying. Start timing once the water reaches a controlled, gentle boil. At 8 minutes, the outside should be tender, the center should still offer slight resistance, and the cubes should hold their shape.
Why do the potatoes need to dry before frying?
Dry surfaces brown better and are safer around hot fat. Let the cubes steam-dry for 5 to 10 minutes, then blot away any remaining surface moisture before adding them to the duck fat.
Can I reuse the potato cooking water?
No. Some soluble oxalates move into the cooking water during boiling, so drain the potatoes and discard that water. Do not reuse it in soup, gravy, or another dish.
