Preparing Your Ingredients and Setting Up
Start by selecting your potatoes—russet or sweet potatoes work great. Wash and peel them if desired, then cut into even-sized fries for uniform cooking.
Preheat your Ninja Air Fryer to 400°F by setting the temperature and letting it warm up for about 3-5 minutes. This ensures your fries cook evenly and get crispy on the outside.
Cooking the Perfect Fries
- Place the cut potatoes into the nonstick basket and spread them in a single layer for even crisping.
- Spritz lightly with cooking spray or toss with a little oil for extra crunch.
- Set the Air Fryer to 400°F and cook for 15-20 minutes, shaking the basket halfway through to ensure even cooking.
- Check for doneness—fries should be golden brown and crispy.
Serving and Tips for Outdoor Enjoyment
Once cooked, serve your fries immediately with your favorite summer dips or toppings. They’re perfect as a side for grilled burgers or hot dogs in your garden.
For extra flavor, sprinkle with herbs or parmesan right after cooking. The Ninja Air Fryer’s dehydrating function also allows you to make dried fruit or jerky for outdoor snacking.
Keep the basket clean and dry after use for easy outdoor clean-up and prepping for your next summer recipe.
