Ingredients

4 cups fresh strawberries, hulled and sliced
3 cups rhubarb stalks, sliced into 1-inch pieces
1 cup granulated sugar
2 tablespoons cornstarch
1 teaspoon vanilla extract
1 1/2 cups old-fashioned rolled oats
1 cup all-purpose flour
1/2 cup packed light brown sugar
1/2 teaspoon ground cinnamon
1/4 teaspoon salt
1/2 cup unsalted butter, cold and cubed

Instructions

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray to prevent sticking.
In a large mixing bowl, combine the sliced strawberries, rhubarb, granulated sugar, cornstarch, and vanilla extract. Toss gently until the fruit is evenly coated. Pour this mixture into the prepared baking dish, spreading it out into an even layer.

To make the topping, in a separate bowl, mix the rolled oats, flour, brown sugar, cinnamon, and salt. Add the cold, cubed butter and use a pastry cutter or your fingers to work the butter into the dry ingredients until the mixture resembles coarse crumbs.
Sprinkle the crumble topping evenly over the fruit filling, covering it completely.
Bake in the preheated oven for 40-45 minutes, or until the topping is golden brown and the filling is bubbling around the edges.

Remove from the oven and allow to cool slightly for 10-15 minutes before serving. This helps the filling set and makes serving easier.

Tips

Use fresh, ripe strawberries and rhubarb for the best flavor. If fresh rhubarb isn’t available, frozen rhubarb can be used—just thaw and drain excess liquid before using.
For a sweeter topping, sprinkle additional brown sugar or add chopped nuts like walnuts or pecans for extra crunch.

If you prefer a gluten-free version, substitute the all-purpose flour with almond flour or gluten-free baking mix, and ensure the oats are certified gluten-free.
To store leftovers, keep the crisp in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving to restore some of the crispiness.

Serving Suggestions

This strawberry rhubarb crisp is delightful served warm with a scoop of vanilla ice cream or a dollop of whipped cream. It also pairs well with a drizzle of fresh cream or Greek yogurt for added richness. For a more decadent treat, sprinkle some chopped nuts or a splash of bourbon into the fruit filling before baking.

Variations

Looking to mix things up? Consider adding a handful of raspberries or blueberries to the fruit mixture for extra color and flavor. You can also swap the crumb topping for a streusel made with chopped nuts, oats, and butter for a more textured topping. For a vegan version, replace the butter with coconut oil or vegan margarine and ensure the oats are certified vegan.

Storage and Reheating

Leftover strawberry rhubarb crisp can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place individual servings in the microwave for 30-45 seconds or reheat the entire dish in a 350°F (175°C) oven for about 15 minutes until warmed through. For best results, reheat just before serving to maintain the crispiness of the topping.

Frequently Asked Questions

Can I use frozen strawberries and rhubarb?

Yes, frozen strawberries and rhubarb can be used in this recipe. Thaw and drain any excess liquid before mixing with the sugar and cornstarch to prevent a soggy filling. Adjust the baking time if needed, as frozen fruit may release more moisture.

Can I make this ahead of time?

Absolutely. You can prepare the fruit filling and topping separately the day before. Assemble the crisp in the baking dish, cover with plastic wrap, and refrigerate. When ready to bake, remove from the fridge and bake as directed, adding an extra 5-10 minutes if necessary.

Is this recipe suitable for gluten-free diets?

Yes, with substitutions. Use certified gluten-free oats and a gluten-free flour alternative like almond flour or gluten-free baking mix. Ensure all other ingredients are gluten-free to keep it safe for those with gluten sensitivities.

How do I know when the crisp is done?

The crisp is ready when the topping turns golden brown and the fruit filling is bubbling around the edges. The baking time is approximately 40-45 minutes at 350°F, but keep an eye on it to prevent over-browning.

Can I freeze leftovers?

Yes, you can freeze individual portions or the entire baked crisp. Allow it to cool completely, then wrap tightly in plastic wrap and foil. Freeze for up to 2 months. To reheat, thaw in the refrigerator overnight and warm in the oven or microwave before serving.

What makes this crisp different from a crumble?

The main difference is the topping. A crisp typically has a crumbly, oat-based topping, while a crumble might include more flour and butter, sometimes with a streusel topping. Both are delicious, but this recipe’s oat topping gives it a distinctive texture and flavor.
