Gathering Your Ingredients
Making delicious sweet potato fries at home requires just a handful of basic ingredients and a few optional additions for customizing flavor. Below is a master list you can adapt to suit your taste.
Essential Ingredients
- 6 whole sweet potatoes, peeled and cut into thin sticks
- 1 stick salted butter (substitute with olive oil for a lighter version)
- 2 cloves garlic, pressed
- 1 tsp seasoned salt (or plain salt; try Lawry’s or your favorite blend)
- 1 tsp chili powder
- 1/2 tsp black pepper
- Extra salt (for sprinkling after baking)
Upgrade Your Seasonings
- Swap or add paprika, onion powder, steak seasoning, cumin, smoked paprika, or cayenne for variety.
- Sprinkle on herbs like thyme or rosemary after baking for an earthy flavor boost.
Dipping Sauces

Mix ketchup with mayonnaise for a tangy “fry sauce,” or blend Sriracha for a spicy mayo kick! These sauces are quick to whip up while the fries bake.
How to Make Sweet Potato Fries: Step-By-Step Directions
Homemade sweet potato fries are all about preparation, seasoning, and proper baking or air frying technique. Below is an expert step-by-step approach for oven-baked fries, with air fryer instructions in a later section.
- Preheat your oven to 450°F (232°C). An extra-hot oven is key for that crave-worthy sizzle and browning.
- Melt the butter in a small saucepan. Skim off any foam for best flavor.
- Mix the seasonings. Stir pressed garlic, seasoned salt, chili powder, and black pepper into the melted butter using a fork until combined.
- Toss the sweet potatoes. Place your cut sweet potato sticks in a large bowl. Pour the butter and seasoning mixture over them, making sure each fry is coated. Use your hands for maximum coverage—get every piece glistening!
- Arrange for even baking. Spread the fries onto two baking sheets, ensuring they aren’t crowded. Space is critical for browning and crispness.
- Bake and shake. Put the trays in the hot oven. Bake for 15 to 17 minutes, shaking the pans once or twice during cooking so the fries brown evenly. They should be sizzling and lightly browned, but watch the edges closely to prevent burning.
- Let them rest. Remove the trays and let the fries sit for 3–5 minutes. This helps the fries firm up and makes them easier to lift off the pan.
- Season while hot. Generously sprinkle the fries with extra salt while they’re still warm for best absorption and flavor.
- Prepare your dipping sauce. While the fries cool, stir together mayonnaise and ketchup (or Sriracha) in a 3:1 ratio—three parts mayo to one part sauce. Mix with a fork to a creamy consistency and a beautiful, salmon-pink color.
- Serve and enjoy! Transfer the fries to a platter and serve alongside your homemade dip.
Pro Tips for Extraordinary Sweet Potato Fries
- Don’t crowd the pan: Overlapping fries steam instead of crisp. Give each stick room to breathe.
- Shake the pans: Move the fries around at least once midway to ensure even browning and prevent sticking.
- Don’t expect extreme crispiness: Oven-baked sweet potato fries will be firm and slightly crispy at the edges, but not shatteringly crunchy like deep-fried versions. Their natural moisture and sugars mean they’re softer inside—but still scrumptious.
- Peeling optional: You can leave some skin on for extra fiber and texture, or peel them fully—it’s up to your taste!
- Customize your spice blend: Use your favorite pantry spices, such as cumin, smoked paprika, garlic powder, or even dried herbs, to make your fries unique.

Air Fryer Sweet Potato Fries: Crispy Results with Less Oil
If you’re looking for extra crispiness and want to skip the oven, the air fryer is your best friend. Here’s how to make air fryer sweet potato fries that come out golden and delicious every time:
- Cut the sweet potatoes into 1/2-inch-thick sticks, about 4–5 inches long. Pat dry with a paper towel.
- Toss with oil and seasoning: Coat the sticks evenly with 2 tsp olive oil, 1 tsp kosher salt, 1/4 tsp cumin, 1/4 tsp cayenne, and 1/4 tsp black pepper.
- Cook in batches: Lay half the fries in a single layer in the air fryer basket with space between. Cook at 380°F (193°C) for 7 minutes. Toss them, space out again, and cook another 7 minutes.
- Repeat: Cook the remaining half the same way.
- Crisp and rewarm: Combine all cooked fries and air fry at 400°F (204°C) for 3–5 minutes more for maximum crunch right before serving.
FAQ: Common Air Fryer Questions
- Do I need to soak sweet potato fries before air frying?
No soaking is needed—sweet potatoes aren’t as starchy as russets, and soaking can actually make them soggy in the air fryer. - Should I peel sweet potatoes for fries?
It’s your choice. The skin adds texture and nutrients, but you can peel for a smoother bite. - How long does each batch take?
About 15 minutes for the first fry (7 + 7 minutes), plus a final 3–5 minutes to crisp all the fries before serving.
Perfect Dipping Sauce Pairings
No sweet potato fry experience is complete without the perfect dip. Here are classic and creative dipping sauce ideas:
- Spicy Mayo: 3 parts mayo, 1 part Sriracha, whisked together until smooth.
- Classic Fry Sauce: 3 parts mayo, 1 part ketchup, mixed until pink and creamy.
- Creamy Honey Mustard: 1/4 cup mayo, 2 tbsp Dijon mustard, 2 tsp honey, whisked to combine.
- Greek Yogurt Garlic Dip: Plain Greek yogurt, minced garlic, lemon juice, and salt.
- Chipotle Ranch: Ranch dressing blended with chipotle in adobo for smoky heat.
Serving Suggestions and Tips
Sweet potato fries can elevate any meal, but they shine as:
- A side dish: Pair with burgers, grilled chicken, sandwich wraps, or steak.
- Appetizer platter: Serve alongside hummus, veggie sticks, and wings for crowd-pleasing finger food.
- Healthy snack: Enjoy solo with your favorite dip for a satisfying, nutrient-rich bite.
- Breakfast treat: Serve under a poached egg with hot sauce for a savory twist on brunch.
How to Store and Reheat Sweet Potato Fries
- Storing: Cool leftovers completely, then store in an airtight container in the fridge for up to 3 days.
- Reheating oven-baked fries: Spread on a baking sheet and bake at 425°F for 5–7 minutes until sizzling.
- Reheating air fryer fries: Return to the air fryer for 3–5 minutes at 400°F for maximum crispness and heat.
- Avoid microwaving—they can become soft and soggy.
Frequently Asked Questions (FAQs)
Q: Why aren’t my sweet potato fries crispy like restaurant fries?
A: Oven-baked sweet potato fries are naturally more tender due to their high sugar and moisture content. Spreading them out and using a hot oven helps maximize crisp edges, but they’ll still be softer than deep-fried versions. For more crunch, use an air fryer or lightly coat with cornstarch before baking.
Q: Can I prep sweet potato fries ahead of time?
A: Yes! Peel and cut your sweet potato sticks up to a day in advance. Store them submerged in cold water in the fridge, then drain and dry thoroughly before tossing with oil and seasonings. This helps them stay fresh and prevents browning.
Q: What’s the best oil to use for fries?
A: Olive oil brings flavor and heart-healthy fats. For a more neutral taste, try canola or avocado oil. Butter adds rich flavor in the oven version, but stick to oils if using an air fryer.
Q: Are sweet potato fries healthier than regular fries?
A: Sweet potatoes offer more vitamin A and fiber compared to russet potatoes, but the overall nutrition depends on portion size and preparation. Baking or air frying is healthier than deep frying.
Q: Can I use frozen sweet potato fries instead?
A: Absolutely! Frozen fries are quick and convenient—just follow the package instructions for baking or air frying, and serve with homemade dipping sauces for a flavor upgrade.
