What You’ll Need
This rhubarb crisp recipe requires simple, readily available ingredients. Here’s a quick rundown:
- Fresh rhubarb: The star of the show! Look for stalks that are firm and vibrant red. About 4 cups chopped will be perfect.
- Granulated sugar: Provides the necessary sweetness to balance the rhubarb’s tartness. Half a cup will do the trick.
- Cornstarch: This thickens the rhubarb filling beautifully, preventing it from becoming watery. One tablespoon is all you need.
- Vanilla extract: A touch of vanilla enhances the overall flavor profile, adding a hint of warmth and complexity. One teaspoon will add that perfect aromatic touch.
- Rolled oats: The foundation of our irresistible crispy topping. Half a cup gives a nice hearty texture.
- All-purpose flour: Helps bind the topping together, creating that perfect crunchy texture. Use half a cup for optimal results.
- Brown sugar: Adds a rich caramel flavor and enhances the topping’s overall sweetness. One-third of a cup is just right.
- Ground cinnamon: A warm, aromatic spice that complements the rhubarb perfectly. Half a teaspoon is all you need for a subtle spice note.
- Cold butter, cut into cubes: Essential for creating that flaky, buttery topping. Use a quarter cup of cold butter for the best texture.
Step-by-Step Instructions
Let’s get baking! This rhubarb crisp recipe is wonderfully straightforward:
- Prepare the rhubarb filling: Preheat your oven to 375°F (190°C). Wash and chop the rhubarb into ½-inch pieces. In a large bowl, gently combine the chopped rhubarb, granulated sugar, cornstarch, and vanilla extract. Mix until everything is evenly coated. Tip: Don’t overmix the filling; a gentle toss is all you need.
- Make the crumble topping: In a separate bowl, combine the rolled oats, flour, brown sugar, and cinnamon. Cut in the cold, cubed butter using a pastry blender or your fingers until the mixture resembles coarse crumbs. Tip: Work quickly to prevent the butter from melting. Cold butter is key to a flaky topping!
- Assemble the crisp: Pour the rhubarb filling into a greased 8×8 inch baking dish or a similar-sized oven-safe dish. Sprinkle the crumble topping evenly over the filling. Tip: For an extra-crispy topping, you can lightly press down on the crumble mixture.
- Bake: Bake for 35-40 minutes, or until the topping is golden brown and the filling is bubbly. Tip: Keep an eye on your crisp during the last 10-15 minutes of baking. If the topping is browning too quickly, loosely cover it with aluminum foil.
- Cool and serve: Let the rhubarb crisp cool slightly before serving. This allows the filling to set up a bit. Serve warm, perhaps with a scoop of vanilla ice cream or a dollop of whipped cream. Tip: A little extra vanilla ice cream is never a bad idea!
Tips for Success
To ensure your rhubarb crisp turns out perfectly every time, here are a few extra tips:
Use ripe but firm rhubarb. Overly soft rhubarb will result in a watery filling. If your rhubarb is particularly tart, you might want to increase the sugar slightly. Make sure your butter is cold – this is crucial for a flaky and crispy topping. Don’t overmix the crumble topping, or it will become dense. And finally, let your crisp cool slightly before serving to allow the filling to set.
Variations to Try
Feel free to experiment with this recipe! Here are a few ideas:
Berry Bliss: Add a cup of your favorite berries (blueberries, raspberries, strawberries) to the rhubarb filling for an extra burst of fruity flavor. Spiced Up: Add a pinch of ginger or nutmeg to the crumble topping for a warm, spiced twist. Gluten-Free: Substitute gluten-free all-purpose flour for the regular flour in the topping. Nutty Delight: Stir in ½ cup chopped nuts (pecans, walnuts, almonds) to the crumble topping for added crunch and flavor.
Storing and Reheating
Leftover rhubarb crisp can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, simply microwave individual portions for 30-60 seconds, or bake in a preheated oven at 350°F (175°C) for 10-15 minutes until heated through. You can also freeze your crisp for longer storage. Allow it to cool completely, wrap it tightly in plastic wrap, and then place it in a freezer-safe bag or container. It can last for up to 2 months in the freezer. To thaw, simply let it sit at room temperature or in the refrigerator until it reaches your desired consistency, then reheat according to the methods mentioned above.
