- Do not thaw the rhubarb fully before mixing; it helps keep the filling from getting too watery.
- Press the oat topping lightly so it holds shape while baking.
- Use cold butter for a flakier topping if you prefer.

- For crunchy topping, bake a few extra minutes at the end.
variation (if any)
- Add 1/2 cup chopped strawberries or raspberries with the rhubarb for a mixed fruit crisp.
- Stir in a pinch of nutmeg or ginger to the topping for warm spice.
- Use chopped nuts (walnuts or pecans) in the topping for more crunch.
FAQs
Q: Can I use fresh rhubarb instead of frozen?
A: Yes. Chop fresh rhubarb and use the same amount. You may need a little less sugar if the rhubarb is sweeter.
Q: Can I make this gluten free?
A: Yes. Use gluten-free oats and a gluten-free flour blend for the topping.
Q: How do I know when it is done?
A: The top should be golden brown and the rhubarb should bubble at the edges. That shows the filling is hot and cooked.
Q: Can I make this ahead?
A: Yes. Assemble it and keep in the fridge for a few hours before baking. Or bake and reheat before serving.
