Our rhubarb crumble with oats is 417 calories per portion and uses just eight ingredients. 

This crumble topping is buttery and crunchy, which perfectly compliments and contrasts the tangy, soft rhubarb pieces. Our recipe is easy to make with only three steps in the method and a total cooking time of 45 minutes. 



  • 1kg rhubarb, trimmed and sliced into chunks
  • 100g soft brown sugar
  • 1 orange, zest and juice

For the crumble:

  • 100g plain flour
  • 100g butter
  • 100g oats
  • 100g sugar
  • 2 pieces of stem ginger, chopped




  1. Heat the oven to 200C (180C fan, Gas 6). Make the crumble filling by putting the rhubarb, brown sugar, orange zest and juice into a saucepan. Bring to the boil and simmer for 5 minutes, until the rhubarb has softened. Tip the rhubarb mixture into an ovenproof baking dish.
  2. To make the crumble topping, put the flour and butter into a large mixing bowl, and rub together with your hands, until it resembles breadcrumbs.Stir in the oats, sugar and stem ginger.
  3. Sprinkle the crumble mixture over the rhubarb and bake for 40 minutes until golden on top.

Top tips for making a rhubarb crumble with oats:

Rhubarb tends to shrink down when cooked, so don't be put off if it looks like too much in your pan initially. You could add a sprinkle of ground ginger or cinnamon to the topping if you want a hint of spice. You could also mix through some chopped nuts for added crunch.

Can you make rhubarb crumble with apples?

Yes you can make a crumble using a combination of apples and rhubarb if you don’t have the full quantity of rhubarb for the recipe. Given the tartness of the rhubarb you might like to use sweeter eating apples such as jazz or pink lady. 

When is rhubarb in season?

Forced rhubarb is available from January to April. It is tender and has a wonderful bright pink colour. Field grown rhubarb is available until late Summer but the stems can have a paler, green colour. 

How long does rhubarb last?

Fresh rhubarb will keep in the fridge for a couple of weeks. If you have lots of rhubarb and want to freeze it, it’s best to cook it first. You could roast or steam it before freezing or preserve it as a pickle instead. 

Give your crumble the presentation it deserves by using a gorgeous oven-proof dish that will look attractive when placed in the centre of your table. We love this one from Le Creuset and it’s available in lots of colours.
