There’s nothing quite like biting into a perfectly roasted potato: crunchy on the outside, tender on the inside, and loaded with flavor. Honestly, they're downright addicting. Around here, they don’t last long on the plate.
Whether we’re serving them up with a cozy plant-based dinner, piling them next to a hearty vegan side, or adding them to a weekend breakfast spread, crispy roasted potatoes are always a hit.
Sure, it takes a little extra effort to get that golden, crackly exterior, but it’s absolutely worth it. Tossing chopped spuds into a hot oven isn't enough. A few key tricks can transform simple potatoes into something seriously special.

1. Parboil Potatoes with Baking Soda and Salt
One of the most effective ways to achieve crispy roasted potatoes is by parboiling them first. This means partially boiling the potatoes before they hit the oven or air fryer. It’s an extra step, but a game-changer for texture.
For best results, add baking soda and salt to the boiling water. The baking soda raises the water’s alkalinity, helping break down the potato’s surface starch. This creates a rough, starchy exterior that crisps beautifully when roasted. Meanwhile, the salt seasons the potatoes all the way through, not just the outer layer.
This method is ideal whether you're roasting in the oven or making air fryer red potatoes. The starchy surface helps develop a crisp crust while keeping the inside tender and creamy. If you're after texture that delivers, don’t skip this prep step.
2. Use Parchment Paper (Not Wax Paper) for Roasting
To prevent sticking and promote even browning, line your baking sheet with parchment paper. Unlike foil, parchment offers a non-stick surface that won’t tear your crispy potatoes apart. It also promotes better airflow and cleaner release from the pan.
Make sure not to confuse parchment paper with wax paper. When it comes to parchment paper vs wax paper, parchment is designed for high-heat applications like roasting. Wax paper, coated with paraffin, can smoke or catch fire in the oven.
If you’re aiming for golden edges and mess-free cleanup, parchment paper is the clear winner.
3. Avoid Overcrowding the Baking Sheet
When potatoes are packed too closely together, they steam instead of roast. That’s a fast track to soft, pale potatoes with no crisp in sight. The key is to give each piece enough breathing room so heat can circulate evenly.
Arrange your potato chunks in a single layer with visible space between them. If you're cooking a large batch, use two trays rather than cramming everything onto one. This ensures consistent browning and that beautiful crisp you’re after.
4. Air Dry the Potatoes Before Roasting
After parboiling, let your potatoes air dry before roasting. Even minimal surface moisture can interfere with crisping.
Let them sit in a colander or spread out on a clean towel for 10–15 minutes. This allows steam to escape and gives the exterior time to dry naturally.
Dry potatoes allow oil to coat the surface more effectively, which enhances browning and prevents steaming. This step is especially important if you’re adding these to a plant-based breakfast plate.
No one wants soggy potatoes next to their tofu scramble or sautéed kale.
5. Roast at a High Temperature and Finish Under the Broiler
Roasting at high heat, at around 450°F, helps develop a golden-brown crust quickly, locking in flavor while keeping the inside soft. Once your potatoes are cooked through, a quick finish under the broiler (just 2–3 minutes) adds that final touch of blistered, crispy edges.
This method also works great in the air fryer. Set it to a high temp and keep an eye on them during the last few minutes.
A bit of broiler time can be the difference between good and restaurant-worthy.

Frequently Asked Questions About Crispy Roasted Potatoes
Potatoes often stick to foil when there isn’t enough oil or the oven isn’t hot enough to form a crust quickly. Use parchment paper or oil both the foil and potatoes generously.
Parboil the potatoes with baking soda, rough up the surface, and roast at high heat with enough oil to create a golden, crispy crust.
Baking soda is best. It breaks down the potato’s surface starch, creating a rough exterior that crisps well. Baking powder is better suited for baked goods.
The best seasonings for oven roasted potatoes?
Go with garlic powder, onion powder, paprika, rosemary, thyme, salt, and black pepper. Sprinkle nutritional yeast or fresh herbs after roasting for an extra layer of flavor.
A small amount of baking soda in the boiling water helps rough up the surface and creates a crispier finish in the oven.
Keep them warm in the oven at 200°F uncovered until serving. Avoid covering or stacking them, which traps steam and softens the crust.
Yukon Gold or Russet potatoes are ideal. Yukon Golds are creamy with a crispy skin; Russets are crispier but fluffier and more delicate inside.
Crispy Roasted Potatoes
Ingredients
- 3 golden potatoes washed and chopped into 1-inch pieces
- 4 cups water or 1 quart
- 2 teaspoons salt
- ½ teaspoon baking soda
- 1 tablespoon avocado oil
- Salt to taste
Instructions
- Preheat the oven to 450°F and line a baking sheet with parchment paper.
- In a large pot, bring 4 cups of water to a boil. Once boiling, stir in 1 teaspoon salt and ½ teaspoon baking soda.
- Carefully add the chopped potatoes to the boiling water. Boil uncovered for 8–10 minutes, or until the edges are just starting to soften.
- Drain the potatoes using a colander, then let them sit for about 10 minutes to steam off excess moisture. This helps achieve a crispier texture.
- Once mostly dry, transfer the potatoes to a large bowl. Add 1 tablespoon oil and a pinch of salt. And any herbs and spices you want to add. Gently toss to coat without breaking the potatoes.
- Arrange the potatoes in a single layer on the prepared baking sheet, leaving space between each piece.
- Roast for 40 minutes, flipping once or twice during cooking, until golden and crispy on all sides.
- For an extra-crispy finish, broil for 1–2 minutes, keeping a close eye to prevent burning.

Hi, thanks so much for the great advice! I was curious if you can get the same level of crispiness with sweet potatoes using the same technique. What do you think?

Hey Nick! I haven't tried this recipe with sweet potatoes, so I am not entirely sure how they will come out.
