Its warm, fruity filling topped with a buttery crumble creates a comforting treat that’s easy to prepare and always a crowd-pleaser.

Ingredients

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

Instructions

Preheat your oven to 375°F (190°C). Grease or butter a 9×13-inch baking dish to prevent sticking.
In a large mixing bowl, combine sliced strawberries, chopped rhubarb, granulated sugar, cornstarch, vanilla extract, and lemon juice. Stir gently until well mixed and set aside to macerate while preparing the topping.

In a separate bowl, prepare the crumble topping by combining rolled oats, flour, brown sugar, cinnamon, and salt. Mix thoroughly.
Add the cold, cubed butter to the dry ingredients. Using a pastry cutter, two forks, or your fingertips, cut the butter into the mixture until it resembles coarse crumbs with some pea-sized pieces.
Pour the fruit mixture into the prepared baking dish, spreading it out evenly. Then, sprinkle the crumble topping evenly over the fruit, covering all the surface.

Bake in the preheated oven for 40-45 minutes, or until the topping is golden brown and the filling is bubbling at the edges.
Remove from the oven and allow to cool for at least 15 minutes before serving. This helps the filling set slightly and makes serving easier.

Tips

Use fresh or frozen strawberries and rhubarb. If using frozen, do not thaw before baking to prevent excess moisture.

For a gluten-free version, substitute the all-purpose flour with almond flour or gluten-free flour blends, but adjust the topping accordingly.
To make the dessert more tart, increase the rhubarb slightly or reduce the sugar in the filling.
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave before serving for best texture.

Serving Suggestions

Serve warm with a scoop of vanilla ice cream, a dollop of whipped cream, or a drizzle of heavy cream for an indulgent dessert. It also pairs beautifully with a cup of tea or coffee for a cozy afternoon treat.

Variations

For a different twist, try adding a handful of chopped almonds or walnuts to the crumble topping for extra crunch. You can also swap out the strawberries for blueberries or raspberries, or add a splash of bourbon to the fruit mixture for a deeper flavor. If you prefer a less sweet dessert, reduce the sugar in the filling and topping accordingly.

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 it in a 350°F (175°C) oven for about 15 minutes or until warmed through. Alternatively, microwave individual portions for 30-60 seconds, but be aware that the topping may lose some of its crispness. For longer storage, the dessert can also be frozen for up to 2 months; thaw overnight in the fridge and reheat as described.

Frequently Asked Questions

Can I use frozen strawberries and rhubarb?

Yes, you can use frozen strawberries and rhubarb. Do not thaw them before baking, as excess moisture can make the filling watery. Simply add them directly to the bowl and proceed with the recipe.

Can I make this ahead of time?

Absolutely. You can prepare the filling and crumble separately, assemble the dish, and refrigerate it for up to 24 hours before baking. Baking may take a few extra minutes if chilled, so keep an eye on it.

What if I don’t have fresh rhubarb?

Frozen rhubarb works well as a substitute. If you only have dried rhubarb, it’s not recommended as it won’t have the same texture and moisture content. Fresh or frozen is best for this recipe.

Can I reduce the sugar in this recipe?

Yes, you can reduce the sugar by up to half for a less sweet dessert, but keep in mind that the natural tartness of the rhubarb and strawberries will be more prominent. Adjust to your taste preference.

Is this recipe suitable for gluten-free diets?

It can be adapted by using gluten-free flour and oats. Just ensure all ingredients are certified gluten-free if necessary. The texture may vary slightly, but it still makes a delicious dessert.

How do I prevent the topping from burning?

To prevent over-browning, you can tent the dish with aluminum foil halfway through baking if the topping looks too dark. Baking at the recommended temperature and keeping an eye on it also helps.
