Peel and dice your sweet potatoes into ½ inch cubes. Try to make them as uniform as possible so that they cook evenly. Add them to a large bowl, then dice the onion and add it into the bowl with the sweet potatoes.

Drizzle your olive oil over the sweet potatoes, and sprinkle in all of the seasonings, including the cajun seasoning, ground cumin, garlic powder, and onion powder. Use a wooden spoon or tongs to mix the oil and seasonings to fully coat the potatoes.

Heat up a large skillet over medium heat for 2-3 minutes. Once it is warm add the sweet potatoes and spread them out into one even layer. Place a lid on the skillet and allow the potatoes to cook for 5-7 minutes untouched.

Remove the lid and gently stir the sweet potatoes around, lifting them from the bottom of the skillet. Try not to mush them up too much- as you want them to get some color and crisp to them.

Leave the lid off now and cook them for another 7-10 minutes, or until they are fork tender. Add salt and pepper to your taste, garnish with chopped parsley or green onions, and enjoy!
