How to Make Oven Baked White Sweet Potato Fries Recipe

Step 1: Prep Your Sweet Potatoes

Start by washing and peeling the Japanese sweet potatoes. Cut them into fry-shaped sticks about ¼ to ½ inch thick. This ensures they cook evenly and achieve that perfect balance of crispy edges and tender centers.

Step 2: Soak to Remove Starches

Place the cut fries into a large bowl and cover with 4 cups of cold water. Let them soak for at least 30 minutes, or up to an hour. This soaking step is a game-changer – it pulls out excess starch so your fries turn out crispier rather than soggy.

Step 3: Preheat and Season

While the fries soak, preheat your oven to 425°F (220°C). Drain the fries and pat them thoroughly dry with a clean kitchen towel to remove moisture. In a bowl, toss the fries with olive oil, salt, and if you like, cornstarch for extra crispiness, followed by garlic powder, paprika, and black pepper. Make sure each fry is coated evenly.

Step 4: Arrange and Bake

Spread the fries in a single layer on a baking sheet lined with parchment paper. Avoid overcrowding to keep them crisp. Bake in the preheated oven for 20-25 minutes, flipping halfway through to ensure even cooking and browning on all sides.

Step 5: Garnish and Enjoy

Once baked to a golden crisp, remove from the oven and sprinkle with fresh cilantro or parsley. Serve immediately to appreciate the full texture and flavor of your homemade Oven Baked White Sweet Potato Fries Recipe.

Garnishes

Fresh herbs like cilantro or parsley add a burst of color and a fresh herbal note that balances the fries’ natural sweetness and spice seasonings beautifully. For a little extra fun, a squeeze of lemon juice or a sprinkle of grated Parmesan can also elevate the experience.

Side Dishes

These fries make an excellent accompaniment to grilled chicken, burgers, or fish tacos. Their subtly sweet and savory flavor complements many protein dishes, making them a versatile side that’s both delicious and nutritious.

Creative Ways to Present

Try serving your fries in a casual cone made from parchment paper for parties or snack time, or pile them high on a vibrant plate with dipping sauces on the side such as garlic aioli, spicy ketchup, or creamy ranch for extra indulgence and flair.

Make Ahead and Storage

Storing Leftovers

If you have leftovers, store them in an airtight container in the refrigerator for up to 3 days. Keep in mind that they will lose some crispiness over time, but careful reheating can bring some of that texture back.

Freezing

You can freeze the uncooked fries after soaking and drying them. Spread them on a baking sheet in a single layer and freeze until solid, then transfer to a freezer bag. Bake them directly from frozen, increasing the cooking time by a few minutes for a crispy finish anytime you desire.

Reheating

To reheat your Oven Baked White Sweet Potato Fries Recipe, place them on a baking sheet and warm them in a 400°F (200°C) oven for about 10 minutes. This refreshes their crispy texture without drying them out.

FAQs

Can I use regular orange sweet potatoes instead of Japanese sweet potatoes?

Yes! Regular orange sweet potatoes will work, but they tend to be moister and less starchy, so soaking and drying well is especially important for crispiness.

Is cornstarch necessary for this recipe?

Cornstarch is optional, but it makes a big difference in creating an extra crispy crust on the fries. If you prefer a lighter texture, you can leave it out.

How long can I soak the fries?

Ideally, soak for at least 30 minutes up to an hour. Soaking longer than an hour won’t improve crispiness and may cause the fries to become waterlogged.

Are these fries healthy?

Absolutely! Baking instead of frying cuts down on oil and calories. Japanese sweet potatoes are packed with vitamins, fiber, and antioxidants, making this a tasty and nutritious snack.

What dipping sauces pair best with these fries?

They’re fantastic with garlic aioli, spicy ketchup, honey mustard, or even a cooling tzatziki. The natural sweetness of the fries complements both creamy and tangy sauces.

Final Thoughts

You really can’t go wrong with this Oven Baked White Sweet Potato Fries Recipe. It’s a simple, satisfying way to enjoy a healthier take on fries while embracing the unique flavor of Japanese sweet potatoes. Whether for a cozy night in or a party treat, these fries will become your new favorite. Give them a try — your taste buds will thank you!
