Step-by-Step Instructions

1. Prep the Sweet Potatoes: Scrub the sweet potatoes clean (you can peel them if desired, but leaving the skin on adds extra fiber and texture). Cut them into 1/4-inch to 1/2-inch thick fries, making sure they are as uniform in size as possible for even cooking.
2. Soak and Dry: Place the cut fries in a large bowl of cold water and soak for 10-15 minutes (no longer, as sweet potatoes absorb water quickly). This removes excess starch and helps them get crispy. Drain and pat completely dry with paper towels—this is crucial for crispiness.
3. Season the Fries: In a large bowl, combine the dried sweet potato fries with olive oil, garlic powder, smoked paprika, salt, pepper, and cayenne (if using). Toss well to coat evenly.
4. Air Fry the Fries: Preheat your RV air fryer to 380°F (190°C). Place the seasoned fries in a single layer in the air fryer basket (cook in batches if needed). Air fry for 12-14 minutes, shaking the basket every 4-5 minutes, until golden brown and crispy.
5. Fire Up the Grill: While the fries are air frying, preheat your grill or grill pan to medium-high heat (around 400°F). For a charcoal grill, create a hot zone by arranging coals to one side. For a gas grill, preheat all burners to medium-high.
6. Grill for Smoky Char: Carefully transfer the air-fried fries to a grill basket or directly onto clean, oiled grill grates (place them perpendicular to the grates to prevent them from falling through). Grill for 2 minutes per side, just until they get light char marks and a smoky aroma.
7. Serve Immediately: Remove the fries from the grill and transfer to a serving plate. Garnish with fresh parsley and serve hot with your favorite dipping sauce.

Grilling Tips for Perfect Healthy Sweet Potato Fries

• Avoid Soggy Fries: Patting the sweet potatoes very dry after soaking is essential. The air fryer creates a super crispy exterior, and the quick grill finish adds smoky flavor without making them soft. Don’t overcrowd the air fryer basket.
• Perfect Char Marks: Use a grill basket to prevent the fries from falling through the grates. If grilling directly, place them perpendicular to the grates for better support. A grill mat also works well.
• Controlling Heat Zones: If using a charcoal or gas grill, set up a two-zone fire. Use the direct heat zone for the quick sear, but move the fries to indirect heat if they start to burn.
• Prevent Sticking: Make sure your grill grates are clean and lightly oiled before adding the fries. A quick wipe with an oil-soaked paper towel (using tongs) right before grilling will do the trick.

Delicious Variations to Try

• Spicy Chili-Lime Fries: Add 1/2 tsp chili powder and the zest of 1 lime to the seasoning mix. Squeeze fresh lime juice over the fries after grilling.
• Garlic-Parmesan Sweet Potato Fries: After grilling, toss the fries with 2 tbsp of melted garlic butter and 1/4 cup of grated Parmesan cheese. Garnish with fresh parsley.
• Maple-Cinnamon Fries: Toss the fries with 1 tbsp of maple syrup, 1/2 tsp of cinnamon, and a pinch of salt before air frying. The sweet and savory combo is delicious.
• Curry-Spiced Fries: Add 1 tsp of curry powder and 1/4 tsp of turmeric to the seasoning mix. The warm, aromatic spices pair perfectly with the sweetness of the potatoes.
• Loaded Sweet Potato Fries: Top the grilled fries with shredded cheddar cheese, crumbled bacon, green onions, and a drizzle of ranch dressing. Return to the grill for 1-2 minutes to melt the cheese.

Storing and Reheating Leftovers

To store: Place leftover fries in an airtight container and refrigerate within 2 hours. They will keep for up to 3 days. For longer storage, freeze them in a single layer on a baking sheet, then transfer to a freezer bag for up to 2 months.

To reheat without losing crispiness: The air fryer is the absolute best way to reheat sweet potato fries. Reheat at 375°F for 4-5 minutes until hot and crispy again. You can also reheat on a grill over medium heat for 2-3 minutes. Avoid microwaving—it makes them soft and soggy.

Frequently Asked Questions (FAQ)

• How long do I air fry sweet potato fries for?
  At 380°F, air fry the sweet potato fries for 12-14 minutes, shaking every 4-5 minutes. The exact time depends on the thickness of the fries and your air fryer model. They should be golden brown and crispy.
• What is the best grill temperature for sweet potato fries?
  For the final grilling step, aim for medium-high heat (around 400°F). This is hot enough to create light char marks and a smoky flavor without burning. Since the fries are already cooked, the grill is just for that finishing touch.
• Can I cook these fries entirely on a charcoal or gas grill?
  Absolutely! You can skip the air fryer and cook the fries directly on the grill using a cast-iron skillet or a grill basket. Grill over medium heat for 15-20 minutes, turning occasionally, until crispy and cooked through. The air fryer method is just quicker and gives a more consistent crunch.
• Why are my sweet potato fries not crispy?
  This is often caused by too much moisture. Make sure to pat the fries very dry after soaking. Also, don’t overcrowd the air fryer basket—give them space for hot air to circulate. Sweet potatoes have more sugar than regular potatoes, which can cause them to brown faster but not get as crispy—this is normal!
• Do I need to peel the sweet potatoes?
  No! Leaving the skin on adds extra fiber, nutrients, and a nice texture. Just make sure to scrub them clean before cutting. Skin-on sweet potato fries are also less likely to stick together.
