How to Make Air Fryer Rhubarb Crisp
For detailed measurements and instructions, jump to the recipe card below.
Step 1
Prepare the Filling: In a large bowl, combine sliced rhubarb, sugar, cornstarch, and ground cinnamon.
Step 2
Prepare the Topping: In another bowl, combine rolled oats, flour, brown sugar, and ground cinnamon. Add the melted butter and mix until the mixture is crumbly.
Step 3
Assemble: Lightly grease a cake pan or baking dish that will fit inside the basket of your air fryer. Spread the rhubarb mixture evenly in the bottom of the dish. Sprinkle the oat topping evenly over the rhubarb.
Step 4
Air Fry: Preheat your air fryer to 350℉. Air fry at 350℉ for 20 minutes, or until the topping is golden brown and the rhubarb is tender and can be pierced with a fork.
Step 5
Serve: Serve the rhubarb crisp with a scoop of vanilla ice cream or a dollop of whipped cream.
Substitutions and Variations
- Fruit: Swap out some of the rhubarb for strawberries or apples to make it sweeter with less tang.
- Nutty: Add chopped pecans or almonds to the topping.
- Gluten-Free: Use gluten-free oats and flour.
How to Store Air Fryer Rhubarb Crisp
Store: Keep leftovers in an airtight container in the refrigerator for up to 3 days.
Reheat: I like it cold the next day, but you can reheat individual portions in the microwave air fryer for a few minutes until warm.
Top Tips
Even Layers: Spread each layer evenly so it cooks properly.
Adjust Sweetness: If your rhubarb is quite tart, add an extra tablespoon or two of sugar. (I always take a bite when I pick it to check). 😉
Cover: If the top is browning too much, cover with aluminum foil.
Common Mistakes to Avoid
- Using Unripe Rhubarb: Use ripe rhubarb as unripe rhubarb can be too tough and tart.
- Skipping the Cornstarch: Cornstarch helps thicken the filling. Without it, the filling will be too watery.
- Not Mixing the Topping Well: Mix the topping so that it is crumbly. You can even use your fingers to mix it.
Air Fryer Rhubarb Crisp FAQs
