Ingredients You’ll Need
For the Fruit Filling:
- 3 cups rhubarb, chopped into 1-inch pieces
- 3 cups apples, peeled and diced (Granny Smith or Honeycrisp work wonderfully)
- ¾ cup granulated sugar
- 2 tablespoons cornstarch
- 1 teaspoon vanilla extract
- 1 tablespoon lemon juice
- ¼ teaspoon salt
For the Crisp Topping:
- 1 cup old-fashioned rolled oats
- ¾ cup all-purpose flour
- ⅔ cup brown sugar, packed
- ½ cup cold butter, cubed
- 1 teaspoon cinnamon
- ¼ teaspoon nutmeg
- Pinch of salt
Step-by-Step Instructions
Preparing the Filling
- First, preheat your oven to 350°F (175°C) and lightly grease a 9×9 inch baking dish.
- Next, combine the chopped rhubarb and diced apples in a large bowl.
- In a separate small bowl, mix together the sugar and cornstarch, then sprinkle this mixture over the fruit.
- After that, add the vanilla extract, lemon juice, and salt to the fruit mixture and toss until everything is well coated.
- Finally, transfer the fruit mixture to your prepared baking dish and spread it out evenly.

Creating the Perfect Crisp Topping
- In a medium bowl, combine the oats, flour, brown sugar, cinnamon, nutmeg, and salt.
- Then, add the cold cubed butter and use a pastry cutter or your fingers to work it into the dry ingredients until the mixture resembles coarse crumbs.
- Subsequently, sprinkle this crumbly topping evenly over the fruit mixture in the baking dish.

Baking Your Apple-Rhubarb Crisp
- Bake in your preheated oven for 40-45 minutes, or until the fruit is bubbling around the edges and the topping is golden brown.
- Afterward, remove from the oven and let it cool for at least 15 minutes before serving.
- Consequently, this cooling period allows the filling to set slightly, making it easier to serve.

Tips for the Perfect Apple-Rhubarb Crisp
- Fruit Preparation: If using frozen rhubarb, there’s no need to thaw it beforehand. However, you may need to increase the baking time slightly.
- Sweetness Level: The amount of sugar can be adjusted based on your preference and the tartness of your rhubarb. Therefore, feel free to add more or less sugar to suit your taste.
- Topping Variations: For additional texture, you can also add chopped nuts like pecans or walnuts to the crisp topping.
- Serving Suggestions: This homemade Apple-Rhubarb Crisp is delicious on its own, but it’s absolutely divine when served warm with a scoop of vanilla ice cream or a dollop of whipped cream.

Instructions
Prepare the Apple-Rhubarb Filling
-
Combine the Fruit
Preheat your oven to 350°F (175°C) and lightly grease a 9×9-inch baking dish. Add the chopped rhubarb and diced apples to a large mixing bowl.
Tart apples like Granny Smith create the best balance with rhubarb’s natural tanginess.
-
Mix the Sweetener and Thickener
In a small bowl, whisk together the granulated sugar and cornstarch. Sprinkle the mixture over the fruit.
Cornstarch helps create a thick, glossy filling as the fruit releases its juices during baking.
-
Flavor the Filling
Add the vanilla extract, lemon juice, and salt. Toss everything together until the fruit is evenly coated.
The lemon juice brightens the flavor and enhances the fruit’s natural sweetness.
-
Transfer to the Baking Dish
Spread the fruit mixture evenly in the prepared baking dish.
An even layer ensures the filling cooks uniformly.
Create the Crisp Topping
-
Mix the Dry Ingredients
In a medium bowl, combine the rolled oats, flour, brown sugar, cinnamon, nutmeg, and a pinch of salt.
Old-fashioned oats provide the classic crisp texture and hearty crunch.
-
Cut in the Butter
Add the cold cubed butter and work it into the dry ingredients using a pastry cutter, fork, or your fingertips until coarse crumbs form.
Cold butter is essential for creating a crumbly, golden topping.
-
Cover the Fruit
Sprinkle the crisp topping evenly over the apple-rhubarb mixture.
Make sure the fruit is fully covered for the best texture and presentation.
Bake Until Golden Brown
-
Bake the Crisp
Place the baking dish in the preheated oven and bake for 40–45 minutes, or until the topping is golden brown and the filling bubbles around the edges.
Bubbling juices indicate the filling has thickened and the fruit is tender.
-
Check for Doneness
The topping should appear crisp and lightly toasted while the fruit underneath is soft.
If the topping browns too quickly, loosely tent the dish with foil during the final minutes of baking.
Cool and Serve
-
Let the Crisp Rest
Remove the apple-rhubarb crisp from the oven and allow it to cool for at least 15 minutes.
Cooling helps the filling set, making it easier to scoop and serve.
-
Enjoy Warm
Serve warm on its own or with a scoop of vanilla ice cream, whipped cream, or a drizzle of caramel sauce.
The combination of sweet apples, tart rhubarb, and crunchy oat topping makes every bite perfectly balanced.
