Ingredients
- 450g (3 cups) fresh strawberries, hulled and halved
- 375g (3 cups) rhubarb stalks, chopped into 1.25 cm (1/2-inch) pieces
- 150g (3/4 cup) granulated sugar
- 30g (1/4 cup) all-purpose flour
- 5ml (1 tsp) vanilla extract
- 15ml (1 tbsp) fresh lemon juice
- 90g (1 cup) old-fashioned rolled oats
- 90g (3/4 cup) all-purpose flour
- 100g (1/2 cup) packed brown sugar
- 2.5ml (1/2 tsp) ground cinnamon
- 1.25ml (1/4 tsp) salt
- 113g (1/2 cup / 1 stick) unsalted butter, cold and cubed
Instructions
- Preheat your oven to 175°C (350°F). Prepare a 20×20 cm (8×8 inch) or a 23×33 cm (9×13 inch) baking dish, lightly greasing it if desired, though usually not necessary for crisps.
- In a medium-sized mixing bowl, gently combine the sliced strawberries and chopped rhubarb. These fruits will soften beautifully, creating a luscious filling. Add the granulated sugar, flour, vanilla extract, and fresh lemon juice. Stir carefully with a spatula until all the fruit pieces are just coated. The flour acts as a thickener, preventing a watery filling, while the lemon juice brightens the flavors.
- Transfer the prepared fruit mixture into your chosen baking dish. Spread it out evenly across the bottom, ensuring a consistent layer for even baking.
- In a separate, larger bowl, whisk together the dry ingredients for the topping: the rolled oats, all-purpose flour, packed brown sugar, ground cinnamon, and salt. Whisking them ensures they are thoroughly combined before adding the butter.
- Add the cold, cubed unsalted butter to the oat mixture. Using a pastry cutter, two knives, or your fingertips, cut the butter into the dry ingredients. Continue until the mixture resembles coarse crumbs with some pea-sized clumps. The key is to keep the butter cold, which creates pockets of steam during baking, resulting in a wonderfully crisp and crumbly topping.
- Sprinkle the oat topping evenly over the fruit filling in the baking dish. Do not press the topping down; a light, airy application will ensure maximum crispness.
- Bake the crisp in the preheated oven for 40-45 minutes. The dish is ready when the fruit filling is visibly bubbling around the edges and the oat topping is golden brown and deliciously crispy. If you notice the topping browning too quickly before the fruit is cooked through, loosely cover the dish with aluminum foil for the remainder of the baking time.
- Once baked, remove the crisp from the oven and let it cool for at least 15 minutes before serving. This crucial resting period allows the hot fruit filling to thicken and set, preventing it from being too runny when scooped.

Tools You’ll Need
- Two large mixing bowls
- 20×20 cm (8×8 inch) or 23×33 cm (9×13 inch) baking dish (or similar 2-liter capacity)
- Pastry cutter (or two knives, or your fingertips)
- Whisk
- Measuring cups and spoons
- Cutting board
- Sharp knife
- Spatula
Essential Success Tips
- Ensure your butter is very cold and cut into small cubes for the topping. This creates a flakier, crispier crumble.
- Avoid overmixing the fruit filling; gently fold the ingredients to keep the fruit intact and prevent it from becoming mushy.
- Use fresh, ripe strawberries and firm rhubarb for the best flavor and texture contrast.
- Do not press the oat topping firmly onto the fruit. A light sprinkle allows for better air circulation and a crispier texture.
- Allow the crisp to cool sufficiently after baking. This step is essential for the fruit filling to thicken and set properly.
Professional Cooking Secrets
- For an extra layer of warmth, lightly toast the rolled oats in a dry pan for a few minutes before adding them to the topping mixture; this enhances their nutty flavor.
- Consider adding a tiny pinch of freshly grated nutmeg or a touch of cardamom to the topping alongside the cinnamon for a more complex spice profile.
- If you prefer a richer, deeper flavor in your topping, use browned butter instead of cold butter. Melt the butter until fragrant and golden brown, then chill it until solid again before cubing and incorporating into the topping mixture.

Notes
- Storage: Leftover crisp can be stored, covered tightly with plastic wrap or foil, in the refrigerator for up to 3 days. It may lose some crispness, but the flavors will still be delicious.
- Reheating: To reheat, place individual servings in the microwave or warm the entire dish in a 150°C (300°F) oven until heated through. For a crisper topping, a toaster oven works wonders for individual portions.
- Variations: For a citrusy twist, add 5ml (1 tsp) of orange zest to the fruit filling. A handful of chopped pecans or walnuts can also be added to the topping for extra crunch and nutty flavor.
Frequently Asked Questions
Can I use frozen strawberries or rhubarb?
Yes, you can use frozen fruit. There's no need to thaw completely; simply toss the frozen fruit directly with the other filling ingredients. Be aware that frozen fruit may release more liquid, so the baking time might be slightly longer, or you might add an extra tablespoon of flour to the fruit mixture.
How do I know when my crisp is perfectly baked?
A perfectly baked crisp will have a deeply golden-brown and crunchy topping, with the fruit filling visibly bubbling vigorously around the edges of the dish. The fruit should be tender when pierced with a fork.
Can I prepare this crisp ahead of time?
You can prepare the fruit filling and the oat topping separately and store them in airtight containers in the refrigerator for up to 24 hours. Assemble the crisp just before baking for the best texture and freshness of the topping.
