Great question. Yes, you can make this apple crisp in a slow cooker! Simply combine all the apple filling ingredients directly in your slow cooker, top with the oat mixture, and cook on LOW for 3-4 hours (removing the lid for the last 30 minutes to help the topping crisp up).

Yes, you can use apple pie filling instead of fresh apples, but the texture will be softer and much sweeter. Since pie filling is already cooked and sugary, skip the brown sugar and cinnamon in the apple layer and go lighter on the topping if you don’t want it overly sweet. It’s a shortcut that works, but the fresh apple version will have more texture and balance.
