Slow-cooker apple crumble

Slow-cooker apple crumble

Make the most of your slow-cooker and whip up an apple crumble recipe that’s sure to be an instant family favourite. To get a perfectly crisp top, all you have to do is cook for the last 10 minutes with the lid slightly ajar. Now, where’s the cream?

  1. Put the slices of apple in a slow-cooker. Sprinkle over the ground cinnamon, orange zest and 1 tbsp juice and mix together.
  2. Put the oats and walnuts into a food processor and pulse a few times to give the texture of very course breadcrumbs. Pour into a bowl.
  3. Stir the ginger, flour and sugar into the oat and walnut mixture then add the butter and mix well.
  4. Spoon the crumble mix over the apples, covering them all. Lay two sheets of kitchen paper or kitchen roll on top of the crumble. Cover with the slow-cooker lid and cook on a low heat for 3½ hrs.
  5. Remove the kitchen paper and cook for the last 10 mins with the lid just slightly ajar.

Tip: Laying kitchen roll on top of the crumble helps prevent condensation dripping back onto the crumble, so you get a more crisp crust.
