Strawberry Rhubarb Oat Crisp (Printable)

A spring dessert combining tart rhubarb and sweet strawberries with a golden oat topping.

# What You Need:

→ Fruit Filling

01 - 3 cups fresh rhubarb, sliced ½-inch thick
02 - 3 cups fresh strawberries, hulled and halved
03 - ¾ cup granulated sugar
04 - 2 tablespoons cornstarch
05 - 1 tablespoon lemon juice
06 - 1 teaspoon vanilla extract

→ Oat Crumble Topping

07 - 1 cup old-fashioned rolled oats
08 - ¾ cup all-purpose flour
09 - ⅔ cup light brown sugar, packed
10 - ½ teaspoon ground cinnamon
11 - ¼ teaspoon salt
12 - ½ cup unsalted butter, cold, cut into small cubes

# Steps:

01 - Set oven to 350°F to ensure proper baking temperature.
02 - In a large bowl, combine rhubarb, strawberries, granulated sugar, cornstarch, lemon juice, and vanilla extract. Toss gently until fruit pieces are evenly coated with the sugar mixture.
03 - Pour the coated fruit mixture into a lightly greased 8x8-inch baking dish, spreading it into an even layer.
04 - In a separate bowl, whisk together rolled oats, flour, brown sugar, cinnamon, and salt. Add cold butter cubes and blend using your fingers or a pastry cutter until the mixture resembles coarse crumbs with some pea-sized butter pieces remaining.
05 - Sprinkle the oat crumble mixture evenly over the fruit filling, covering completely.
06 - Bake for 35-40 minutes until the topping is golden brown and the fruit filling is bubbling vigorously around the edges of the dish.
07 - Allow the crisp to cool for at least 10 minutes before serving. Serve warm, optionally topped with vanilla ice cream.

# Expert Advice:

01 -
  • The contrast between tart rhubarb and sweet strawberries creates this incredible balance that never feels too sugary.
  • That oat crumble topping gets perfectly golden and crisp while staying tender underneath, like the best kind of breakfast granola met a fruit pie and fell in love.
02 -
  • I once made the mistake of using softened butter for the crumble and ended up with a dense, doughy topping instead of those crispy clusters we all love.
  • Letting the crisp cool for those 10 minutes seems impossible when it smells this good, but it makes a huge difference in the texture.
03 -
  • If you are using frozen rhubarb or strawberries, thaw them first and drain off any excess liquid before adding the cornstarch.
  • For extra crunch, try adding half a cup of chopped pecans or almonds to the crumble mixture.
