How to Make Classic Rhubarb Crisp
Preheat the oven and prepare your baking dish

In another bowl, mix oats, flour, brown sugar, salt, and cinnamon. Then work in the butter until you get coarse crumbs.
Assemble the crisp layers

Bake until golden and bubbling

Tips for the Best Rhubarb Crisp
How to prevent a watery filling
Frozen rhubarb releases extra moisture. So, add a little more flour if needed. Also, bake a bit longer until bubbling thickens.
Getting the perfect crumbly topping texture
Use cold butter and mix until crumbs form. Do not overmix, or the topping may turn dense.
Adjusting sweetness to taste
Rhubarb tastes quite tart. Therefore, adjust sugar based on your preference. You can start with less and taste the mixture.
Baking tips when using frozen rhubarb
Do not thaw the rhubarb first. Instead, bake slightly longer so the filling cooks through properly.
