Step-By-Step Guide: Baked Sweet Potato Fries with Aioli
A hot oven and even slices are the only real hurdles here, and both are easier than they sound. Once things get going, the recipe almost runs itself.
Step 1: Preheat the Oven
Preheat your oven to 425°F (220°C). A hot oven is key for achieving that crispy texture. — The heat hits the pan fast, which always feels like a good sign.
Step 2: Prepare the Sweet Potatoes
Wash, peel, and cut the sweet potatoes into thin, even sticks. This ensures they cook evenly.
Tip: Aim for about 1/4 inch thickness for the perfect fry.
Step 3: Season the Fries
In a large mixing bowl, toss the sweet potato sticks with olive oil, garlic powder, paprika, salt, and pepper until well-coated. — The spices cling quickly; a little shake helps them settle in.
Step 4: Bake the Fries
Spread the seasoned fries evenly on a baking sheet lined with parchment paper. Ensure they are in a single layer to promote crispiness.
Bake for 20-25 minutes, flipping halfway through, until they’re golden and crispy. — The flip is where you can feel which fries are crisping first.
Step 5: Make the Aioli
While the fries are baking, mix mayonnaise, minced garlic, lemon juice, and salt in a small bowl until smooth.
Tip: Adjust the garlic level to your preference for a milder or stronger flavor.
Option note: If using a different mayonnaise, taste test to find the right balance of flavors.
Step 6: Serve and Enjoy
Once the fries are done, remove them from the oven and let them cool slightly. Serve alongside the creamy aioli for dipping. — That first fry is always hotter than expected, but worth it.

Pro Tips for Baked Sweet Potato Fries With Aioli
A few small adjustments can make the fries come out exactly the way you want them.
- For extra crispiness, soak the cut sweet potatoes in cold water for 30 minutes before baking, then drain and dry thoroughly.
- Play with spices like cayenne pepper or cinnamon for a unique twist.
- Use fresh herbs, like rosemary or thyme, tossed with your fries for added fragrance.
- If you prefer a lighter aioli, substitute Greek yogurt for half of the mayonnaise.
- Always keep an eye on the fries in the oven, as they can go from perfect to burnt quickly.

Dietary Variations & Substitutions
Gluten-Free Version
- The recipe is naturally gluten-free as sweet potatoes are gluten-free; ensure all seasonings and mayonnaise are gluten-free certified.
- For extra crispiness, soak the sweet potatoes in cold water before baking.
Tip: Watch for doneness as gluten-free items can sometimes cook faster.

Tip: A splash of apple cider vinegar can enhance the tanginess in dairy-free aioli.

Low-Sugar

- To keep it that way, avoid sweetening the aioli; use fresh herbs for flavor instead.

Common Mistakes to Avoid

Too much oil can result in greasy fries.
Tip: Just enough to coat is perfect for desired crispness.
