This Apple Rhubarb Crisp is my favorite easy dessert recipe. It's packed with sweet apples and tart rhubarb, topped with a crunchy oat and cinnamon streusel and always gets raves reviews!
Is it Apple Rhubarb Crisp or Apple Rhubarb crumble? Whatever you want you want to call it, it is delicious!
Traditionally a crisp has oats and a crumble doesn't but many people use the terms interchangeably. This recipe is a traditional crisp, topped with an oat cinnamon streusel, but I won't get mad if you call it a crumble.
After all, apples and rhubarb are always a good idea, especially when they are baked into this delicious dessert. Sweet apples are the perfect balance with a tart rhubarb making this easy ,make-ahead dessert a winner.

FAQ
Use your favorite apple but make sure it is a firm apple that will hold its shape after baking and not turn mushy. Granny Smith, Honeycrisp, and McIntosh are some of our favorites.
Fresh is always easy to get when it's in season but this recipe can be made with frozen rhubarb, too. Frozen rhubarb will have a lot more water, so be sure to defrost it and drain off the extra liquid before tossing it with the sugar and cornstarch. If there is excess liquid, you can add additional corn starch.
Crisps and crumbles are easy to make gluten-free! Just be sure to use gluten-free oats and flour in the streusel mixture.
Expert Tips for making Apple Rhubarb Crisp
- Adjust the sugar according to your apples and your preferences. If you want it more tart, add a little less sugar. If you prefer sweeter desserts, add an additional ¼ cup sugar.
- If you use frozen rhubarb, make sure you thaw it first and drain off the extra liquid otherwise your crisp filling may be runny.
- Like a lot of streusel topping? Double the topping recipe for an extra thick layer.
- If you are serving the crisp directly from the oven, let it sit for 15-20 minutes before serving to let the juices thicken.
- Don't have any rhubarb on hand? You can easily make this recipe with all apples and it will be just as delicious!
