This comforting dish pairs juicy strawberries and tart rhubarb beneath a golden, buttery oat crumble. With a simple preparation of mixing fresh fruit with sugar and cornstarch, it bakes into a bubbling filling topped by a crunchy, cinnamon-spiced crumble. Served warm, it’s perfect with vanilla ice cream for added creaminess. Adaptable with frozen fruit or nuts, it offers a classic American dessert experience suitable for vegetarians.
The first time I saw rhubarb at the farmers market, I thought someone was selling weird pink celery by mistake. Then the vendor caught me staring and offered me a raw stalk to try. My mouth puckered so hard she laughed, but she promised that with sugar and strawberries, it transforms into something magical. That evening, I made my first crisp and watched my skeptical family go back for third helpings.
My neighbor grows rhubarb like its going out of style and started leaving bags of it on my porch every spring. At first I panicked, not knowing what to do with all that pink bounty. Now I spot those bags on my doorstep and immediately preheat the oven, knowing exactly what kind of comfort is coming.
Ingredients
- Fresh strawberries: Quarter them so they cook down evenly with the rhubarb into that perfect jam consistency
- Rhubarb: Slice it about half an inch thick so it holds some texture while becoming tender
- Granulated sugar: This sweetens the tart rhubarb without overpowering the strawberries natural flavor
- Cornstarch: The secret to getting that thickened fruit juices instead of a soupy mess
- Vanilla extract: Pure vanilla makes everything taste better and bridges the gap between the two fruits
- Lemon juice: Brightens everything up and enhances the strawberry flavor
- All purpose flour: Provides structure for the crumble topping so it holds together
- Old fashioned rolled oats: Use these not quick oats for better texture and nutty flavor
- Light brown sugar: Adds caramel notes and helps the topping get wonderfully crisp
- Ground cinnamon: Just a hint to warm up all those bright fruit flavors
- Unsalted butter: Keep it cold and cut it into small cubes before mixing

Last summer I made this for a potluck and watched it disappear in ten minutes flat. Three different people asked for the recipe while they were still scraping their bowls clean.
Making It Year Round
Frozen fruit works perfectly here so you dont have to wait for strawberry season. Just toss them in frozen and add about five extra minutes to the baking time. Nobody will be able to tell the difference.
Getting The Texture Right
The key is cutting butter into the flour mixture until it looks like coarse sand with some pea sized pieces remaining. Those larger butter pockets create those delicious crispy bites that make a crisp so addictive.
Serving Suggestions
Vanilla ice cream is classic but a dollop of Greek yogurt adds a nice tangy contrast. For extra decadence, serve with whipped cream flavored with a little orange zest.
- Warm it up slightly the next day in the microwave
- The topping stays surprisingly crisp overnight
- Breakfast the next morning is totally acceptable
There is something deeply satisfying about a dessert that looks impressive but comes together with such ease.
