We love a hearty dessert in our home. An air fryer is a great way to cook things quickly, and easily too. I love that my air fryer sits on the worktop and I don’t have to lift heavy dishes into the oven.
Air fryer rhubarb crumble has to be one of our favourite air fryer desserts. It’s so simple and tastes just a couple of minutes to prepare. Best of all we’ve got a huge rhubarb crown in our garden which produces lots of rhubarb throughout the warmer months.
I often serve a nice pudding after we have a roast dinner, or if it is a special dinner occasion. Knowing that I can make some individual desserts, in a matter of minutes, is fantastic!
We are BIG fans of sweet recipes here, with some of the current favourite in our home being banana bread, banana chocolate chip muffins, midnight cookies, air fryer apple crumble and rhubarb and pineapple crumble.

Do you cook rhubarb before making crumble?
Personally I don’t feel you need to. This crumble went down really well, it was lovely. This had a crispy top and was soft inside and that works really well with delicious hot custard.
What fruit pairs well with rhubarb?
I feel that apples, pears and strawberries all work really well with rhubarb based desserts. We’ve also used pineapple in the past and this was a lovely balance of bitterness and sweetness that you don’t often get with desserts.
Making a strawberry rhubarb version of this crumble is always a winner too!
We have a rhubarb plant in our garden and this year we’ve been fortunate that is has been prolific. We’ve had 10s of stalks of rhubarb in just a few weeks, which is fantastic.
I can’t believe that the tiny little rhubarb crown we were given by a relative less than two years ago is working so well in our garden! Maybe we ARE people who can grow things!
What to serve with rhubarb crumble?
It has to be custard doesn’t it! OR a nice dollop of vanilla ice cream if you like something a little different.
Make your own, buy it from the shop, whatever you fancy, just slather this in a delicious hot custard!
Can you reheat this crumble?
You can pop this in the microwave, for about 1 minute until piping hot, however, I’d suggest eating it fresh from the air fryer.
Make a few ramekins up, pop them in the fridge (they’ll keep for 2 days at least) and then cook from fresh when you want to enjoy a tasty dessert.
These are my favourite air fryer cookbooks and accessories:
Can you make this rhubarb crumble in the Ninja Foodi?
Yes, absolutely! I made my recipe in a Ninja Foodi, I have the 15-in-1 model and I use the air crisp mode for this, which is the same as air frying. This dish can be known as rhubarb crisp sometimes too.
It works with the same timings and temperatures, and I love that there is quite a lot of space to allow me to cook multiple crumbles at the same time which is very convenient.
Can you make a crumble with frozen rhubarb?
Yes, you can make it, however I’d add 2-3 minutes to the cooking time, just to ensure the rhubarb is cooked through.
Personally I like to make this crumble fresh, from scratch, as I feel it has the best taste.
Something to note about air fryer recipes is that all air fryers have different sizes, depths and as such the cooking times can vary. All air fryer recipes on this website are intended as a guide, and not a guarantee that the timings will be perfect. Enjoy!
