🛒 Ingredients You’ll Need for Classic Rhubarb Crisp

  • 4 cups fresh or frozen rhubarb, chopped into 1-inch pieces
  • 1 cup granulated sugar
  • ½ teaspoon ground cinnamon (for the filling)
  • ½ cup brown sugar, packed

  • 1 cup rolled oats (old-fashioned)

🍳 Step-by-Step Instructions for This Rhubarb Crisp Recipe

Let’s walk through how to make this delicious homemade rhubarb crisp recipe step by step. You’ll have a bubbling, golden dessert ready in no time!

  1. Prep Your Oven & Dish: Preheat your oven to 375°F (190°C). Lightly grease an 8×8 or 9×9 inch baking dish.
  2. Prepare the Rhubarb Filling: In a large bowl, combine the chopped rhubarb, granulated sugar, and ½ teaspoon ground cinnamon. Stir gently to coat. Let this mixture sit for 10-15 minutes while you prepare the topping; this helps the rhubarb soften and release some juices, essential for a great rhubarb crisp.
  3. Make the Oat Topping: In a separate medium bowl, mix the brown sugar, all-purpose flour, rolled oats, the remaining 1 teaspoon ground cinnamon, and a pinch of salt.
  4. Add the Butter: Pour the melted butter over the dry ingredients. Stir with a fork or your fingers until the mixture is crumbly and resembles coarse wet sand – the perfect texture for a rhubarb crisp topping.
  5. Assemble the Crisp: Pour the rhubarb mixture into the prepared baking dish, spreading it evenly. Spoon the oat crumble topping over the rhubarb, making sure it covers the fruit completely.
  6. Bake to Golden Perfection: Place the dish in the preheated oven. Bake for 35-40 minutes, or until the topping is golden brown and the fruit filling is bubbling visibly around the edges. This is how you know your rhubarb crisp is ready!
  7. Cool Slightly & Serve: Remove the crisp from the oven and let it cool on a wire rack for 10-15 minutes before serving. This allows the filling to thicken slightly. Serve your warm rhubarb crisp!

💡 Expert Tips for Making the Best Rhubarb Crisp

Making a perfect rhubarb crisp is simple, but these little tips can make it even better:

  • Choose Good Rhubarb: Look for firm, crisp stalks. While color can vary, brighter red stalks are often sweeter and more visually appealing for your rhubarb crisp.
  • Using Frozen Rhubarb: If using frozen, thaw it completely and drain off any excess liquid. This prevents the rhubarb crisp from becoming watery.
  • Don’t Overwork the Topping: Mix the topping ingredients just until combined and crumbly. Overmixing can develop the gluten in the flour, resulting in a less tender crumble for your crisp.
  • How to Tell It’s Done: You’ll see the rhubarb filling bubbling around the edges, and the topping will be a deep golden brown. If the top browns too quickly, you can loosely tent your rhubarb crisp with foil.
  • Balance the Sweetness: Rhubarb is very tart! The sugar amount here is balanced for average tartness, but you can slightly adjust to your preference or the tartness of your rhubarb when making the crisp.

🍽️ Serving Suggestions for Your Rhubarb Crisp

While this Rhubarb Crisp is utterly delicious straight from the dish with just a spoon, here are a few ways to make it extra special:

  • Vanilla Ice Cream: This is the absolute classic pairing for rhubarb crisp. The cold, melting ice cream against the warm crisp is pure bliss.
  • Whipped Cream: A dollop of fresh, lightly sweetened whipped cream is always a welcome addition to a slice of rhubarb crisp.
  • Custard Sauce: For an extra decadent treat, serve it with a warm vanilla custard sauce alongside your rhubarb crisp.

🥡 Storage and Freezing Instructions for Rhubarb Crisp

Need to store leftovers or make ahead? Here’s how to handle your homemade rhubarb crisp:

Storage: Cover any leftover crisp tightly with plastic wrap or transfer it to an airtight container. Refrigerate for up to 4-5 days. Reheat individual servings in the microwave or a larger portion of your rhubarb crisp in a 300°F (150°C) oven until warmed through.

Freezing: To freeze baked rhubarb crisp, let it cool completely. Wrap the dish tightly in plastic wrap, then in foil. Freeze for up to 3 months. Thaw overnight in the refrigerator. Reheat covered in a 325°F (160°C) oven until hot and bubbling, about 20-30 minutes.

❓ Frequently Asked Questions (FAQs) about This Rhubarb Crisp Recipe
