Ingredients and Preparation

Strawberries – They bring natural sweetness and juiciness. Fresh is best for flavor and texture, but frozen strawberries also work if you’re short on time or cooking off-season.

Rhubarb – The star of the show. This vegetable (yes, vegetable!) offers a bold tartness that beautifully complements the berries. If using frozen rhubarb, chop before freezing and don’t worry about thawing.

Sugar (Granulated and Brown) – Granulated sugar balances the tartness in the filling, while brown sugar adds depth and a hint of molasses to the crumble topping.

Cornstarch – Acts as a thickener for the fruit filling. It ensures you get a gooey base instead of a watery mess. Don’t skip it unless you’re using another thickener like arrowroot powder.

All-Purpose Flour – Forms the base of the crumble. It helps create those perfect, buttery crumbles on top.

Unsalted Butter – Cold and cut into chunks, it gives the crumble its rich, melt-in-your-mouth texture. You can swap in vegan butter for a dairy-free version.

Cinnamon – Adds warmth and spice to the topping. You can try nutmeg or cardamom for a different twist.

Salt – Just a pinch boosts all the other flavors.

Optional Add-Ins – Try oats in the topping for texture, lemon zest in the fruit mix for brightness, or a splash of vanilla extract.

Step-by-Step Instructions

Step 1
Preheat your oven to 375°F (190°C) and place the rack in the middle. Lightly grease a 9×9-inch baking dish with cooking spray or butter. This will help prevent sticking and make cleanup easier.

Step 2
In a large mixing bowl, combine chopped strawberries and rhubarb. Add sugar, cornstarch, and a pinch of salt. Toss everything gently until the fruit is evenly coated. Pour this mixture into the prepared baking dish and spread it out evenly.

Step 3
In a separate medium bowl, stir together flour, brown sugar, granulated sugar, cinnamon, and salt. Add cold butter pieces and use your hands (or a pastry cutter) to work it into the dry ingredients until you form coarse, moist clumps. These buttery nuggets will crisp up beautifully.

Step 4
Sprinkle the crumble mixture evenly over the fruit layer. It’s okay if it’s rustic-looking—imperfections make it charming.

Step 5
Place your dish on a foil-lined baking sheet (to catch any bubbling fruit) and bake for 40–45 minutes. You’ll know it’s ready when the top is golden and the fruit is bubbling around the edges.

Step 6
Let the crumble cool for about 10–15 minutes before serving. This allows the filling to thicken up slightly and makes it easier to scoop.

Beginner Tips and Notes

If your topping starts browning too quickly, lightly cover it with foil during the last 10 minutes of baking.

Using frozen fruit? You can skip thawing, but do drain any excess juice if you decide to defrost it.

Don’t overwork the butter into the topping; keeping it chunky is key to getting that perfect crumble texture.

Out of cornstarch? A tablespoon of flour or arrowroot can also thicken the filling.

If you don’t have a pastry cutter, use two forks or even your fingertips—just work quickly to keep the butter from melting.

Serving Suggestions

Serve warm with a generous scoop of vanilla ice cream or a dollop of whipped cream for a comforting contrast of textures. If you’re feeling fancy, drizzle over some warm custard or a spoonful of yogurt for a lighter option.

Pair this easy sheet pan dessert with grilled chicken or a fresh salad for a beautifully balanced meal.

Leftovers? Store in an airtight container in the fridge for up to 4 days. Reheat in the microwave for a quick treat or warm it in the oven at 350°F for 15 minutes to restore the crisp topping.

Want to freeze it? Cool the crumble completely and freeze in a sealed container. It’s best consumed within 2 months. Thaw in the fridge overnight and reheat before serving.
