Preparing Your Ingredients for the Perfect Summer Sides
Start by gathering fresh, seasonal vegetables like zucchini, bell peppers, and cherry tomatoes for roasting or grilling-inspired sides. For crispy snacks, prepare sliced pickles or potato wedges. Use the smart thermometer to ensure ingredients reach the ideal doneness, especially for baked dishes like mac and cheese.
Pre-cut and season your ingredients ahead of time to streamline the cooking process. The Ninja DoubleStack XL’s two baskets let you cook different items simultaneously, like veggies in one and snacks in the other, saving time during your busy summer cookout.

- Place seasoned zucchini, bell peppers, and cherry tomatoes in one basket, and arrange sliced pickles in the other basket.
- Set the timer for 12-15 minutes, using the smart doneness control to monitor crispiness.
- Halfway through, shake the baskets gently to ensure even cooking.
- Once done, remove the vegetables and pickles, and serve immediately for a crispy, flavorful summer snack or side.
Tip: Use the included crisper plates for extra crispiness, and utilize the meal racks to keep cooked items warm while finishing others.
