How to Make Classic Rhubarb Crisp

Step 1: Prep the Oven and Dish

Preheat the oven to 350°F.

Step 2: Make the Rhubarb Filling

Chop the rhubarb and mix it with granulated sugar, cornstarch, orange zest, and vanilla extract. Pour into a 9-inch pie pan, 9×9 inch baking dish or 7×11 baking dish.

Step 3: Make the Oat Topping

In a bowl, mix oats, flour, brown sugar, cinnamon, and salt. Cut in the cold butter (or coconut oil/vegan butter) until crumbly.

Step 4: Assemble and Bake

Pour the oat topping over the rhubarb filling. Bake for 45-50 minutes, until golden brown and bubbly.

Step 5: Cool and Serve

Cool for 30 minutes to 1 hour, then serve warm.

Pro Tips for Making the Recipe

Use Cold Butter: Cold butter helps create a crumbly topping.
Cut Rhubarb Evenly: This ensures even cooking.
Don’t Overfill: Leave some room at the top of the dish to prevent bubbling over.
If you do not have orange zest, lemon zest is a good substitute.
