Ingredients
- For the Rhubarb Filling:
- 6 cups fresh rhubarb, cut into 1/2-inch pieces (about 1.5 lbs)
- 1/2 cup granulated sugar (adjust to taste based on rhubarb tartness)
- 1/4 cup light brown sugar, packed
- 1/4 cup all-purpose flour (or cornstarch for gluten-free option)
- 1 teaspoon vanilla extract
- 1/4 teaspoon ground cinnamon
- Pinch of salt
- For the Buttery Oat Topping:
- 1 cup all-purpose flour
- 1/2 cup old-fashioned rolled oats
- 1/2 cup light brown sugar, packed
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon salt
- 1/2 cup (1 stick) unsalted butter, cold and cut into small pieces
Instructions
- Preheat your oven to 375°F (190°C). Lightly grease an 8×8 inch or 9-inch round baking dish.
- In a large bowl, combine the cut rhubarb, granulated sugar, brown sugar, flour, vanilla extract, cinnamon, and a pinch of salt. Toss gently until the rhubarb is evenly coated. Pour the mixture into the prepared baking dish and spread it evenly.
- In a separate medium bowl, prepare the topping. Whisk together the flour, rolled oats, brown sugar, cinnamon, and salt.
- Add the cold, cut butter to the dry topping ingredients. Using your fingertips, a pastry blender, or a fork, cut the butter into the mixture until coarse crumbs form and some larger pea-sized clumps remain.
- Evenly sprinkle the buttery oat topping over the rhubarb filling in the baking dish.
- Bake for 40-45 minutes, or until the topping is golden brown and the rhubarb filling is bubbly and tender when pierced with a knife. If the topping starts to brown too quickly, you can loosely cover it with foil.
- Remove from oven and let the crisp cool for at least 15-20 minutes before serving. This allows the filling to set and become perfectly jammy.
Notes
Serving Suggestion: Enjoy warm with a scoop of vanilla bean ice cream, a dollop of whipped cream, or a drizzle of heavy cream for an extra luxurious treat. Make Ahead: You can assemble the crisp a few hours in advance and refrigerate before baking. Add an extra 5-10 minutes to the baking time if baking from cold. Storage: Leftovers can be stored covered in the refrigerator for up to 3-4 days. Reheat gently in the oven or microwave. Spice It Up: For an extra layer of flavor, consider adding a pinch of ground ginger or cardamom to the rhubarb filling. Gluten-Free Option: Substitute the all-purpose flour in the filling with cornstarch (use 2 tablespoons) and use a gluten-free all-purpose flour blend (with xanthan gum) for the topping. Ensure oats are certified gluten-free.
