Ingredients

Ingredients
For the Fruity Base
3 cups strawberries trimmed and sliced
3 cups rhubarb cut into small chunks
⅔ cup white sugar
1 tablespoon cornstarch
1 teaspoon vanilla extract
1 tablespoon fresh lemon juice
For the Crunchy Topping
1 cup rolled oats
½ cup all-purpose flour
½ cup brown sugar
½ teaspoon ground cinnamon
¼ teaspoon salt
½ cup melted butter

Method

1. Prep the Oven and Dish

Preheat your oven to 375°F (190°C). Lightly coat an 8×8-inch baking dish with butter or nonstick spray to prevent sticking.

2. Mix the Fruit Filling

In a large mixing bowl, combine the strawberries and rhubarb. Add sugar, cornstarch, vanilla, and lemon juice. Toss everything together until the fruit looks glossy and evenly coated. Transfer the mixture into your prepared baking dish and spread it out evenly.

3. Create the Crisp Topping

In a separate bowl, stir together oats, flour, brown sugar, cinnamon, and salt. Pour in the melted butter and mix until the texture becomes crumbly and slightly clumpy.

4. Assemble and Bake

Scatter the topping evenly over the fruit layer. Bake for 35–40 minutes, or until the top turns golden and the filling bubbles up around the edges.

5. Let It Rest & Serve

Allow the crisp to sit for about 10–15 minutes before serving. This helps the filling set slightly. Serve warm for the best texture and flavor.

Notes

Pro Tips for the Perfect Crisp

Balance sweetness naturally: If your strawberries are very sweet, slightly reduce the sugar.
Don’t skip cornstarch: This keeps the filling thick—not watery.
Cold butter works too: For chunkier topping, use cold butter instead of melted.
Even topping = even crunch: Spread it gently without pressing down.

How to Store & Reheat

Fridge: Cover and store for up to 4 days
Reheat (best method): Warm in oven at 300°F for about 10 minutes to keep topping crisp

From frozen: Bake at 350°F until heated through

Bonus tip: It tastes surprisingly good cold—especially with yogurt the next morning 👀

FAQs

Can I use frozen fruit?

Yes, but thaw and drain well to avoid excess moisture.

What if I don’t have oats?

You can replace them with extra flour, but the texture will be less hearty.

Can I make this gluten-free?

Absolutely—just swap the flour with a gluten-free blend.

Why is my crisp runny?

It likely needs more thickener or more cooling time before serving.
