Ingredients

  • Red skinned potatoes
  • Salt
  • Avocado oil (or olive oil) spray

How to make vegan roasted potatoes in the oven

  1. Cut the potatoes into 1/2 inch cubes (about the size of dice) so they will cook quickly and uniformly. You can leave the skin on or take it off. 
  2. Rinse the potatoes in water after cutting to help remove some of the starch before cooking. Drain off water with a mesh strainer.
  3. Use parchment paper or silicone liner down on a rimmed baking tray. Add potatoes to a baking tray, and spray them with avocado oil or add 1 tablespoon of avocado oil to the potatoes. Sprinkle with salt and stir with your hands or two large spoons. Press the potatoes down so they are in one even layer.
  4. Roast the potatoes at 450F for 35-40 minutes total. After 25 minutes of cooking, take the potatoes out of the oven and move them around with a spatula so they are sure to brown on all sides.

Top tips

Don’t overcrowd the sheet pan: To make sure you have super crispy potatoes, it’s important that you use a baking sheet that is large enough that the potatoes have room around them. You don’t want a mountain of potatoes in the oven, or they will not cook uniformly. I always recommend an extra large baking sheet so food can roast instead of steam!

Cook roasted potatoes faster

If you want to cook vegan roasted potatoes faster, skip step 2 above and instead add the potatoes to a large bowl and microwaving them for 5 minutes. Carefully remove from the microwave, add to the baking sheet with avocado oil and salt.

Bake at 450F for 20-25 minutes, taking the potatoes out after 15 minutes and stirring up the pan to ensure all sides get browned.

Tips to cut potatoes for roasting

To cut potatoes for roasting, you will want to cut the potatoes into even size cubes. 

  • To do this I like to first cut the potato in half so there is a flat surface to work with. 
  • Lay the potatoes down flat and cut them into long logs. Once they are in logs, turn them on the side and cut them into 1/2 inch matchsticks.
  • Cut the matchsticks down into 1/2 inch cubes. 

The best potatoes for roasting

  • I almost always use red-skinned potatoes. Other great options include Yukon gold or round white potatoes. 
  • You can also use fingerling potatoes in this recipe. Fingerlings are great because they require less chopping (because they are smaller) but may require an extra few minutes of roasting to achieve the same level of crunchy coating. 

How to serve roasted potatoes

Here are some of my favorite ways:

How to store vegan roasted potatoes

Fridge: Roasted potatoes can be stored in the fridge for up to 5 days in an airtight container.

Freezer: Once the potatoes are cooked and completely cooled down, you can store them in a freezer safe bag for up to 6 weeks. Defrost in the fridge or use from frozen. 

Tip: When reheating from frozen using the oven or air fryer, add 3-4 minutes to oven time or 1-2 minutes to air fryer if frozen. 

How to reheat potatoes

Roasted potatoes tend to get a little soggy in the fridge! Don’t worry though, you can have equally crispy potatoes the next day! To get the potatoes crispy, you can use the oven or air fryer! 

  • Oven: preheat the oven (or toaster oven) to 400F and bake for 10 minutes until crispy and reheated.
  • Air fryer: Turn the air fryer to 350F and bake for 6-7 minutes, making sure not to overcrowd the air fryer.
