How to Make It

Start your journey to an easy dessert with these simple steps.

Preheat the Oven

Preheat your oven to 350°F (175°C) and lightly grease your baking dish with butter or non-stick spray.

Combine the Fruit

In a medium bowl, combine the strawberries, rhubarb, granulated sugar, lemon juice, and vanilla extract if using. Toss gently to coat all the fruit evenly and let it sit while you prepare the topping.

Prepare the Topping

In another bowl, mix the rolled oats, all-purpose flour, brown sugar, cinnamon, and salt.

Cut in the Butter

Add the cold, cubed butter to the dry ingredients. Use a pastry cutter, two forks, or your fingertips to cut the butter into the mixture until it resembles coarse crumbs with some pea-sized pieces.

Layer the Dish

Pour the fruit mixture into the prepared baking dish, spreading it evenly.

Add the Topping

Sprinkle the oat topping evenly over the fruit, covering all the berries and rhubarb.

Bake the Crisp

Bake for 40 to 45 minutes until the topping is golden brown and the fruit filling is bubbling around the edges.

Cool Before Serving

Let the crisp cool for 10-15 minutes before serving to allow the filling to thicken.

How to Store It

Fridge: Store in an airtight container for up to 3 days.
Freezer: Yes, can be frozen for up to 3 months.
Reheat: Microwave for 30-60 seconds or bake at 350°F for 10 minutes.

Tips for Best Results

  • Use fresh, ripe strawberries for the best flavor.
  • Ensure your butter is cold for a crispier topping.
  • Let the dessert cool slightly before serving for better consistency.
  • Add a scoop of vanilla ice cream for an extra treat.

Serving Suggestions

  • Enjoy it warm with a dollop of whipped cream.
  • Pair it with vanilla ice cream for an indulgent dessert.
  • Serve at summer gatherings alongside grilled meats.
