Preheat the oven to 425F.
Line a large rimmed baking sheet with parchment paper
Place the coconut oil in a large bowl and nuke for about 20 seconds to melt.
Peel the sweet potato and slice into equal width sticks. My cutting board has inch-marks on it, so I can make sure they're even. But I'm weird like that. Ideal stick size would be 3" long and 1/4 thick.
Dump all the sticks in the bowl with the melted coconut oil. If you're like me, you'll dirty a wooden spoon to mix it all together. Make sure all the sweet potatoes are evenly coated with the oil. You can also sprinkle in some salt now, making sure it's mixed evenly.
Dump the sweet potatoes on your prepared baking pan. Spread them out in an single layer. Don't overcrowd the pan, they won't get crispy. I like to get all OCD and line my fries up in even little rows. Don't be weird like me.
Put the baking pan in the middle rack of your oven. Bake for 20-30 minutes, flipping once if you want. After the 20-minute mark, keep an eye on them to make sure they don't burn. A few will, but I always say it's fine to lose a few for the greater good. You want the rest to be nice a crispy.
Remove from oven when they're nice and brown on the edges (not too dark).
