Step-by-Step Cooking Instructions
Pre-Cooking Prep
Preheat your oven to 350°F and lightly grease an 8×8-inch baking dish.
In a large bowl, combine sliced strawberries, chopped rhubarb, lemon juice, vanilla extract, and honey or maple syrup. Toss gently until evenly coated.
Transfer the fruit mixture to the prepared baking dish and spread into an even layer.
Cooking Method (Baking)
In another bowl, mix rolled oats, flour, cinnamon, and salt.
Add melted coconut oil or butter and stir until the mixture becomes crumbly but sticks together when pressed.
Sprinkle the oat topping evenly over the fruit, covering it completely.
Bake uncovered for 35–40 minutes, or until the fruit is bubbling around the edges and the topping is golden brown.
Doneness or Texture Check
The crisp is done when the topping is lightly browned and the fruit filling is thick and bubbly. If the topping browns too quickly, loosely cover with foil during the last 10 minutes.
Resting or Final Touches
Let the crisp cool for at least 10 minutes before serving. This allows the filling to thicken and makes serving easier.
