Ingredients for roasted sweet potatoes

For this recipe, I used:

  • sweet potatoes: here I used red sweet potatoes, but feel free to try other varieties like purple sweet potatoes. The purple version is tasty, really healthy for you and looks incredible.
  • oil: I usually use olive oil for this recipe, but have used coconut oil as well. You can also use avocado, grapeseed or any other mild vegetable oil.
  • salt
  • pepper: black pepper, pepper flakes, paprika, or whatever you prefer can be used here – even fresh minced pepper. Here I tried pepper flakes and the potatoes had a nice spicy kick.
  • seasonings: although I kept this recipe very simple, you can always add more seasonings from fresh chives, thyme and rosemary to oregano, sage and more.

How to make this roasted sweet potatoes recipe

Step 1: Preheat the oven at 425°F. You’ll want that oven nice and hot for roasting.

Step 2: Wash the sweet potatoes to remove any dirt on the skin. You can leave the skin on or peel it off. I usually peel under running water to prevent the sap from overly sticking to my hands.

Step 3: Cut the sweet potatoes into half-inch to 1-inch pieces and add them to a large bowl filled with water. This prevents the pieces from oxidizing and discoloring.

Step 4: Rinse the pieces a couple times.

Step 5: Add the olive oil, salt, pepper and any optional seasonings to the sweet potato pieces. Toss to coat fully.

Step 7: Bake in the oven for 15 minutes. Remove and turn the pieces over. Add the tray back to the oven and bake for another 15 minutes before removing again and turning again. Pop back into the oven one last time and bake for 10 to 15 more minutes or until the pieces have cooked all the way through.
