Preparing the Veggies and Skewers
Choose a variety of summer vegetables like bell peppers, zucchini, cherry tomatoes, and red onion. Cut them into uniform pieces for even cooking. Soak wooden skewers in water for at least 30 minutes to prevent burning.
Assemble the skewers by alternating vegetables, creating a colorful pattern. Season with olive oil, salt, pepper, and your favorite herbs or spices for extra flavor.
Cooking with the Ninja DoubleStack XL Air Fryer
Preheat your Ninja DoubleStack XL Air Fryer to 400°F using the air fry function. Place the skewers in one of the baskets, ensuring they are not overcrowded for proper air circulation. Use the second basket for additional vegetables or sides, if desired.
Set the smart doneness control and use the built-in thermometer to monitor progress. Cook for about 10-12 minutes, turning the skewers halfway through, until vegetables are tender and slightly charred.
Finishing Touches and Serving Tips
Once cooked, carefully remove the skewers and garnish with fresh herbs like parsley or basil. Serve immediately with a side of hummus, tzatziki, or a light vinaigrette for a refreshing summer meal.
For extra flavor, brush the skewers with a balsamic glaze or sprinkle with crumbled feta cheese before serving. Enjoy your healthy, smoky veggie skewers without the hassle of outdoor grilling!
Additional Tips for Perfect Summer Dishes
- Use the double-stack feature to cook multiple dishes simultaneously—perfect for summer cookouts.
- Adjust the cooking time based on vegetable size and your preferred doneness.
- Experiment with different marinades and herbs for variety.
