This rhubarb and ginger crumble is a simple but delicious treat. The filling is full of the delicious flavour of rhubarb, tart but sweet with a hint of stem ginger. The topping is crumbly and buttery with just a little crunch from added almonds.
The humble crumble is a simple but always welcome treat. I am a huge fan of crumbles, whether it’s a classic apple crumble or pear crumble, we love them! They’re really easy to make with minimum fuss. Perfect for pudding after Sunday lunch or as a summer treat, especially on those cooler summer days!
I have been making this rhubarb crumble for years now, it’s a firm family favourite and always goes down a treat. It’s so easy to make with just 4 simple steps. I add some chopped almonds to the topping for added texture along with some oats. I also add some stem ginger to the rhubarb which adds a little zing to the filling!

Recipe And Ingredient Notes
- Rhubarb – main crop rhubarb is available during the Spring months but you can also make this earlier in the year using forced rhubarb. Rhubarb is quite tart so if you want you can add more sugar to the filling I like the balance of tart and sweet so if you’re like me then just follow the recipe as is. When buying rhubarb look for firm, crisp plump stalks with fresh-looking leaves and bright colour.
- Stem ginger – I use stem ginger in syrup for this recipe. You will find this in the baking aisle in mall larger supermarkets. Stem ginger is the preserved fresh young roots of the ginger plant cooked slowly. In the US stem ginger is called candied ginger or crystallized ginger.
- Oats – I use jumbo oats for this crumble you can use any oats except instant.
- Butter – salted butter is my choice of butter for this recipe. If you use unsalted butter I would add a small pinch of salt to the topping. If you want to make this vegan then you can easily make the topping using vegan butter and make sure your sugar is vegan too.
- Pro-tip #1 – make sure the butter is really cold before you use it. I cut the butter into cubes then place it in the freezer for about 20 minutes before I make this.
- Pro-tip #2 – using a food processor saves so much time but if you don’t have one don’t worry. Just follow the instructions here to make the filling then stir in the chopped nuts.
- Variations – fresh strawberries are also great with rhubarb, I would ditch the ginger if I add strawberries. If you can’t find stem ginger you can substitute ground or fresh ginger. I would use 1/4 a teaspoon of ground ginger or 1/2 a teaspoon of freshly grated ginger.
How To Serve Rhubarb and Ginger Crumble
During the summer we love this with a good vanilla ice cream. This is also really good with whipped cream, pouring cream or with some creamy hot custard.
FAQs About This Recipe
Do I need to peel rhubarb for this crumble? If you are using forced rhubarb it should be tender enough that it doesn’t need to be peeled. Maincrop rhubarb can sometimes have tough, stringy ribs, so after washing it, strip these off with a small, sharp knife and slice as instructed.
Can I freeze rhubarb crumble? Yes, you can. I prefer to freeze this before cooking it. Put the filling in a buttered pie dish then sprinkle the topping over it. Press the topping down firmly cover the dish really well then freeze. I defrost this in the fridge overnight before baking.
How do you store rhubarb crumble? If you have any crumble leftover simply keep it on the countertop until cooled them move to the fridge and eat within 3-4 days. You can reheat it if you want but it’s really good cold too.
