Gather Your Ingredients and Prepare the Fruit
Start by selecting your favorite frozen fruit such as berries, peaches, or a mix. You’ll need about 4 cups of fruit, a tablespoon of sugar or honey, a teaspoon of lemon juice, and a handful of oats and nuts for the topping.
Mix the fruit with sugar and lemon juice in a bowl, then set aside while you prepare the topping.
Assemble and Preheat the Ninja Foodi XL Oven
Place the oven in preheat mode, setting it to bake at 375°F. The Ninja Foodi’s rapid preheat (about 90 seconds) ensures you won’t wait long. Use the Smart Thermometer to monitor internal temperature if you want precise control.
While preheating, assemble your dessert in a suitable baking dish, layering the fruit with a topping made from oats, nuts, and a touch of butter or oil.
Bake the Fruit Crisp to Perfection
Insert the assembled dish into the oven, setting it to bake for 20-25 minutes. Use the bake function for even heat distribution, allowing the fruit to soften and the topping to turn golden brown.
The True Surround Convection ensures your crisp is cooked evenly, with no hot spots.
Serve and Enjoy Your Summer Dessert
Remove the crisp from the oven and let it cool slightly. Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream for the perfect summer treat.
Enjoy the combination of warm, fruity filling and crunchy topping as a delightful end to your summer meal.
Tips for Perfect Results
- Use frozen fruit directly from the freezer—no need to thaw.
- Adjust the baking time if your fruit is particularly juicy or dry.
- Experiment with different nuts or spices in the topping for variety.
- Utilize the oven’s dehydrating function for making fruit chips to serve alongside.
