Why You'll Love Baked Sweet Potato Fries:
Crispy Without Frying: High-heat baking and proper spacing help the fries brown nicely without deep frying.
Bold, Balanced Flavor: Paprika and cayenne add warmth while still letting the sweet potatoes shine.
Creamy Dipping Sauce: The Sriracha lime aioli adds a tangy, slightly spicy contrast that pairs perfectly with the fries.
Easy Oven Method: Simple prep and one pan make this a low-effort side or snack.
Versatile Side Dish: Works well with burgers, sandwiches, or as a stand-alone appetizer.
Key Ingredients:
- sweet potatoes. Choose firm, orange-fleshed sweet potatoes for the best flavor and texture. Cut into evenly sized matchsticks or wedges for even cooking.
- paprika. Adds smoky depth without overpowering. Smoked paprika can be used if you want a bolder flavor.
- cayenne pepper. Brings a little heat. Adjust to taste or omit for a milder version.
- sriracha lime aioli (optional). A bold, creamy dip made with mayo, fresh garlic, lime juice, and Sriracha. Adjust the Sriracha to your heat preference.

Easy Substitutions & Variations:
- Make Them Milder: Skip the cayenne or reduce the Sriracha for a less spicy version.
- Dairy-Free Option: Use a dairy-free mayonnaise for the Sriracha lime aioli.
- Change the Seasoning: Swap paprika for smoked paprika or chili powder for a different flavor profile.
- Air Fryer Method: Cook the fries in the air fryer at 380°F for 12-15 minutes, shaking halfway through.

How to Make Sweet Potato Fries:
- Preheat the oven to 425°F and line a large baking sheet with parchment paper.
- Peel the sweet potatoes if desired, then slice into thin, even matchsticks or wedges.
- In a large bowl, toss the sweet potato fries with olive oil, paprika, cayenne pepper, and a pinch of salt until evenly coated.
- Spread fries in a single layer on the prepared baking sheet, do not overcrowd. Bake for 25-30 minutes, flipping halfway through, until browned and crisp at the edges.
- In a small bowl, stir together mayonnaise, Sriracha, minced garlic, lime juice, and a pinch of salt. Taste and adjust heat or acidity as needed.
- Sprinkle fries with more salt to taste. Serve hot with aioli on the side for dipping.
Recipe Notes & Tips:
- Cut Evenly: Slice the sweet potatoes into uniform pieces so they cook at the same rate.
- Don't Overcrowd the Pan: Space the fries out to allow air to circulate and encourage browning.
- Flip Halfway Through: Turning the fries helps them brown evenly on all sides.
- Bake on High Heat: A hot oven helps the fries develop crisp edges without frying.
- Serve Immediately: Sweet potato fries are best enjoyed hot, as they soften as they cool.

I tried this last night as a side to braaied lamb chops and salad. It was AMAZING! We did not make the sauce because we've cut out dairy for a while, but if it's so good alone, I'm sure the sauce just adds something amazing to it too! #drool
