Strawberry Rhubarb Crisp Oats (Printable)

Golden oat crumble with juicy strawberries and tangy rhubarb, baked warm and ready to enjoy.

# What You Need:

→ Fruit Filling

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

→ Oat Crumble Topping

08 - 3/4 cup old-fashioned rolled oats
09 - 3/4 cup all-purpose flour
10 - 1/2 cup light brown sugar, packed
11 - 1/4 cup granulated sugar
12 - 1/2 teaspoon ground cinnamon
13 - 1/4 teaspoon salt
14 - 1/2 cup unsalted butter, cold and diced

# Steps:

01 - Preheat oven to 350°F. Lightly grease a 9-inch square baking dish with butter or cooking spray.
02 - Combine rhubarb, strawberries, granulated sugar, cornstarch, vanilla extract, lemon juice, and salt in a large bowl. Toss thoroughly until fruit is evenly coated, then transfer to prepared baking dish and spread into an even layer.
03 - Whisk together oats, flour, brown sugar, granulated sugar, cinnamon, and salt in a medium bowl. Add cold butter cubes and work into dry ingredients using fingertips or pastry blender until mixture resembles coarse crumbs with some pea-sized pieces remaining.
04 - Sprinkle crumble topping evenly over fruit mixture. Bake for 40 minutes until topping is golden brown and fruit filling is bubbling vigorously around edges.
05 - Let crisp cool for at least 15 minutes to allow filling to set. Serve warm or at room temperature with vanilla ice cream or whipped cream.

# Expert Advice:

01 -
  • The tangy rhubarb meets sweet strawberries in perfect harmony, creating that old-fashioned flavor profile that's impossible to replicate with anything else.
  • Zero stress involved—no rolling dough, no lattice weaving, just tossing fruit and crumbling toppings together.
  • Your kitchen will smell like pure heaven, and the golden bubbling edges are nature's timer telling you it's ready.
02 -
  • Cold butter creates crisp; room temperature butter creates a texture that's more like wet sand. If you're making this last-minute, pop your butter in the freezer for 10 minutes before starting.
  • The bubbling you see around the edges is your signal that the cornstarch has activated and the filling has thickened properly. No bubbles equals runny fruit.
03 -
  • If your rhubarb seems especially thick or fibrous, cut it into smaller 1/4-inch pieces so it breaks down nicely during baking.
  • Place a baking sheet on the rack below your crisp to catch any fruit overflow—bubble-over is a sign of success but a pain to clean.
