Spicy Sweet Potato Fries

Spicy Sweet Potato Fries
Sweet potatoes are one of my favorite veggies, but I never paid much attention the variety until they became my go-to baby food puree. I was in full-on first time mother research mode.

Now I even know the difference between sweet potatoes and yams.

Usually I play it safe and stick to the plump, copper-skinned, orange-fleshed standard tubers, but then I discovered Japanese sweet potatoes.

With their slender shape, purple skin and white flesh, Japanese sweet potatoes are much starchier than their cousins and more dense. I used think that sweet potatoes are always orange. I was so wrong.

It should be pretty obvious that different varieties of sweet potatoes are better for certain cooking methods than other. Just like regular potatoes! Hello!?

Japanese sweet potatoes have more starch, which makes the ideal for oven fries. The challenge with baking fries instead of frying them is getting the crisp outside and fluffy inside without cooking them in a vat of oil.

I like french fries, but I don’t love the guilt that comes with eating real fries. They are such a saturated fat, high calorie belly buster. 

The first step is soaking the sliced potatoes in cold water for an hour before toweling them off and baking them. This helps the fries turn out crispier. 

To give the potatoes some heat, I tossed them in a blend of seasonings including paprika and cayenne pepper, adding a dose of heat. These spicy sweet potato fries were far more flavorful than the usual fried version.

On multiple occasions, I have eaten a plate of these fries for dinner…with a salad, of course! 

It’s better than just baking whole potato because the surfaces of each fry are coated in that spicy  seasoning mix. They don’t need to be dipped into anything, but you can do ketchup if you want or pesto
