Preparing Your Summer Side Dishes
Start by gathering your favorite vegetables and seasonings. For this recipe, we’ll make crispy zucchini fries and seasoned sweet potato wedges—both perfect summer favorites.
Pre-cut your vegetables into the desired shapes and season them with olive oil, salt, pepper, and your favorite herbs or spices. The Ninja DoubleStack XL’s large capacity makes it easy to prepare multiple dishes at once.
Step-by-Step Cooking Instructions
- Set up your Ninja DoubleStack XL Air Fryer on your kitchen counter and place the baskets inside. Preheat the air fryer to 400°F using the air fry function.
- Divide your seasoned vegetables evenly between the two baskets. You can cook the zucchini fries in one and sweet potato wedges in the other, thanks to the independent controls.
- Insert the crisper plates to ensure crispy results. Use the smart doneness control feature to monitor the cooking process and adjust if needed.
- Set the timer for 15-20 minutes, shaking the baskets halfway through for even crispiness.
- Once done, carefully remove the baskets and serve your crispy, flavorful sides hot off the fryer.
Tips for Perfect Summer Sides
- Use a light coating of olive oil for extra crispness without excess fat.
- Adjust cooking time based on your vegetable thickness and desired crispiness.
- Utilize the smart thermometer for precise doneness, especially when roasting or baking.
- Experiment with different seasonings like paprika, garlic powder, or herbs for added flavor.
- Arrange the vegetables in a single layer for even cooking and crisping.
Cleaning and Maintenance Tips
Allow the air fryer to cool before cleaning. Remove the baskets and crisper plates, then wash with warm, soapy water. The space-saving design makes storage easy, and keeping the components clean ensures optimal performance for your summer gatherings.
