Ingredients:

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

Oven Instructions:

  • Step 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. 
  • Step 2: Rinse the potatoes in water after cutting to help remove some of the starch before cooking. Drain off water with a mesh strainer.
  • Step 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.
  • Step 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.
Steps to making roasted potatoes.

Air fryer instructions:

  • Cut the potatoes into 1/2 inch cubes (about the size of dice) so they will not cook quickly and uniformly. You can leave the skin on or peel it off. 
  • In a large bowl, toss the diced potatoes in 1 tablespoon of avocado oil and salt (and seasoning, if added).
  • Place potatoes into the air fryer basket. Make sure to not overcrowd basket. You will likely have to do this in 2 batches for the amount of potatoes in this recipe listed. 
  • Set the air fryer to 375 degrees for 20 minutes. Be sure to shake the air fryer basket 2-3 times throughout the cooking process. Add an additional 5 minutes if you want them extra crispy!

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!

To cook roasted potatoes faster:

If you want to cook 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. 

get my 10 greatest recipes ebook by signing up for my newsletterGET 10 OF MY ALL TIME GREATEST RECIPES
IN THIS FREE EBOOK

  • 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. 

Which potatoes are best 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

These Whole30 roasted potatoes are so versatile! Serve for breakfast, lunch, brunch or dinner. Here are some of my favorite ways:

  • With oven poached eggs for a breakfast hash!
  • On the side of everything bagel smoked salmon and asparagus for a simple healthy meal.
  • Topped with chimichurri sauce on a burrito bowl
  • With curry salmon cakes and 5 minute creamy kale!

Storage:

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.

Substitutions:

  • Potatoes– Any potato will work in this recipe. You could even try this with sweet potatoes, rutabagas or turnips! 
  • Spices – This recipe is simple so that it can be very versatile. However, you can easily take this recipe to the next level by adding your favorite spices (about 1 tablespoon)! Here are some great ideas: 
    • Cajun seasoning
    • Taco seasoning
    • Ranch seasoning
    • Italian seasoning
    • Adding additional salt and vinegar at the end of roasting. 
  • Oil – Avocado oil or olive oil are great options. You can also use coconut oil or melted ghee.

      Kate mashed potatoes are their own beast! When you cook those, just be sure to start with cold water, add all the potatoes then turn on the pot. Cut all your potatoes to the same size and they should cook the same. Drain and mash quickly or they will get gummy! MMMMM all the good stuff sounds amazing!!

    These look so yummy! We like to grill potatoes mixed with peas, carrots and onions then a little butter. Wrap it al in tin foil and then they get grilled nice and crispy on the outdoor grill. So good!
