Preparing Your Ingredients
Start by gathering fresh summer vegetables like zucchinis and sweet potatoes. Wash and dry them thoroughly. Slice the zucchinis into thin fries, about 1/4 inch thick, and cut the sweet potatoes into wedges.
For a crispy coating, mix a tablespoon of olive oil with your favorite seasonings—paprika, garlic powder, salt, and pepper work well. Toss the sliced vegetables in the mixture until evenly coated.
Prepare your crisper plates and meal racks from the Ninja DoubleStack XL, setting the stage for efficient cooking.
Cooking with the Ninja DoubleStack XL
Set the Ninja DoubleStack XL to the ‘Air Fry’ function. Place the coated zucchini fries on one crisper plate, and the sweet potato wedges on the other, utilizing the two baskets independently for simultaneous cooking.
Adjust the smart doneness control with the built-in thermometer to ensure perfect crispiness without overcooking. Typically, cook the zucchini for about 12-15 minutes and the sweet potatoes for 15-20 minutes, shaking or flipping halfway through.
Use the meal racks to stack or expand capacity if preparing larger quantities—this feature makes it easy to serve a crowd.
Finishing Touches and Serving
Once the vegetables are golden and crispy, carefully remove them from the air fryer. Taste and adjust seasoning if needed—perhaps a sprinkle of fresh herbs or a squeeze of lemon for added flavor.
Serve your crispy summer sides alongside grilled meats, burgers, or salads for a complete meal. The Ninja DoubleStack XL ensures everything stays warm and crispy until served, making your summer feast effortless and delicious.
Remember, cleaning is simple with removable baskets and accessories—just wash and dry for next time.
