Baked Sweet Potato Fries

Baked Sweet Potato Fries have crispy, crunchy outsides and tasty tender insides. They’re healthier than the deep-fried version, and they’re easier than you think to make.

Who doesn’t love a good side of fries with lunch or dinner? Sign me up.

And if you love things on the sweeter side, you’re in luck.

Sweet Potatoes are just that, sweeter than an ordinary potato, such as a Russet or Yukon potato.

Plus, after making these several times, I have a tip I want to share with you.

A homemade fry dipped in homemade ketchup.

Making Baked Sweet Potato Fries

First off, do not preheat the oven.

I know, I know…it goes against everything you’ve ever been told about baking anything.

However, for this recipe, you won’t be turning the oven on until the fries are in there.

While this is important, it’s not the tip I mentioned.

So, before we go any further, I need to tell you what the TIP is before I forget.

Do not use a dark cookie sheet for this. No, no, no. They will burn every time.

I couldn’t figure out what I was doing wrong…why did the bottoms keep burning?

I forgot I usually bake them on the silver cookie sheet, and that made all the difference.

So, get out a SILVER cookie sheet and line it with foil. Spray it with non-stick spray. You’ll also need a piece of foil to cover with.

Do I have to peel the sweet potatoes?

I peel the sweet potatoes, but you don’t have to. It’s a preference thing.

The peel actually has vitamins in it, so that’s your call.

If you like the peel on, make sure you wash the potatoes first.

Next, cut 3/4″ thick rounds, which you can cut into smaller pieces if you want.

Bite-sized pieces would be my preference, so I cut larger rounds into halves or quarters.

Place the potato pieces in a bowl and add the olive oil. Stir to coat so everything looks shiny.

Sweet Potatoes and Spices

Add the remaining spices and stir so that everything looks evenly coated.

For this recipe, I spice with salt, black pepper, garlic powder, and dried thyme.

If you love other spices, such as sage or paprika, then you should use those.

Or, run an experiment: spice half with thyme, the other half with your usual favorite spice.

Let me know in the comments if you tried another spice and how you liked it.

Put the pieces on the sprayed foil in a single layer, and cover them with the second piece of foil.

Covering them with the foil cooks the sweet potatoes in their own steam making the insides tender.

Place the cookie sheet in the oven and turn the oven on to 425°.

Set your timer for 30 minutes.

When the timer goes off, take the potatoes out of the oven and remove the foil cover.

Next, flip the potatoes carefully. Even though you sprayed the foil, they still might stick.

Bake for another 25 minutes.

Now, in my oven, they’re done, but check them first.

Check by flipping a few over and if they’re brown and crispy enough for you, they’re done.

If not, flip the rest over and set the timer for another 10 – 15 minutes.

I’d rather give you a specific time, but every oven is different.

For crispier fries:

You can either cut into smaller pieces, or bake them longer.

Dinner ideas:

Here’s one of my comfort food dinners I make in my home:

Comfort food: meatloaf, fries, and homemade ketchup.First, I make the Asian Ground Beef Meatloaf topped with Homemade Asian Ketchup.

Then, I make the Baked Sweet Potato Fries and then dip both the meatloaf and the fries in the ketchup.

It’s a homemade happy meal.
