Preheat the oven to 375°F. In a small bowl, combine the flour, baking powder, lemon zest, sugar, and a pinch of salt. Stir in the melted butter until the mixture forms a crumbly topping, then set aside.

Clean and hull the strawberries and cut the rhubarb into ½-inch pieces. Add the fruit to a mixing bowl and toss with the sugar, lemon juice, cornstarch, and a pinch of salt until evenly coated.

Transfer the fruit mixture to a casserole dish and spread it into an even layer. Sprinkle the crumble topping evenly over the fruit.


Bake for about 50 minutes, until the topping is golden brown and the fruit is bubbling in the center. Remove from the oven and let the dessert cool for at least 15 minutes before serving so the filling can set slightly.
How To Serve Strawberry and Rhubarb Crumble
It’s the perfect dessert to a meal of Smoked Chicken, delish pork chops, or this vegetarian stew, and it makes a great dish for a potluck or picnic.

Chef Jenn’s Tips
- Use fresh fruit. Frozen and thawed fruit can be used but you’ll have to completely thaw the fruit first, then drain it. Otherwise your rhubarb strawberry crumble will be a soupy mess!
- Don’t forget the lemon juice! You can skip the zest, but the fruit really does need a good two tablespoons of lemon juice to give them some acidity and to balance out the sweetness.
- I’ve already cut back on the sugar in this dish, but you could trim a bit more sugar from the fruit filling if you like it on the tart side
- If your crumble starts getting too brown in the oven before the fruit is bubbling in the middle, cover the top loosely with foil.

Rhubarb and Strawberry Crumble
Ingredients
- 1 1/2 cups all purpose flour
- 1 tsp baking powder
- 5 tbsp white granulated sugar
- 1 tsp lemon zest
- 1 pinch salt
- 1/2 cup butter melted
- 2 cups chopped rhubarb
- 1 lb strawberries hulled and quartered
- 2 tbsp lemon juice
- 1/2 cup white granulated sugar
- 4 tbsp cornstarch
- 1 pinch salt
Instructions
For the crumble:
- Combine the flour, baking powder, sugar, lemon zest and a good pinch of salt in a small bowl.
- Melt the butter then add it to the flour mixture, blending well to combine. Set aside.
For the fruit filling:
- Combine the cut rhubarb with the quartered (or sliced) strawberries along with the lemon juice, sugar, cornstarch, and another pinch of salt. Mix well.
Assemble
- Layer the fruit on the bottom of an 8 x 8 oven-safe casserole dish. Using a spoon or your fingers, drop teaspoon sized clumps of the crumble on the top of the fruit. Try to get a fairly even layer.
- Bake the dish in a pre-heated 375-F oven for about 45-50 minutes or until the top is golden brown and the fruit is bubbly and transparent in the middle.
- Let cool and enjoy!

Love summer crumbles, and strawberry rhubarb combination is perfect! Will be great with some vanilla ice cream.
It’s so rare to get fresh rhubarb in my neck of the woods, so when I saw it I immediately grabbed some and went in search of a new recipe to try. This was the perfect recipe – I am only sorry I can’t get rhubarb more often.
