Wash and dry potatoes. Cut into 1 inch pieces and place in a large bowl.
Add olive oil, sumac, and salt to the bowl. Toss until combined.
Spread out potatoes on a baking sheet. Bake for 20 minutes, then toss and cook for another 15-20 minutes until potatoes are roasted and tender when pierced with a fork.
Notes
Potatoes may take a little longer or shorter to cook based on your oven and how large you cut the potatoes. Make sure to pierce them with a fork to test for doneness before serving.
If you want to add more seasonings, add some harissa powder, paprika, or garlic powder to increase the flavor.
