Strawberry Peach Crisp

April 21, 2026

The best kind of summer dessert is the one that makes your kitchen smell like caramelized fruit and warm brown sugar before you’ve even set the table. This strawberry peach crisp does exactly that—juicy peaches and strawberries underneath, with a buttery oat crumble that bakes up crisp on top and a little tender where it meets the fruit.

What makes this one stand out is the simple two-step topping: you press half into the pan like a quick crust, then scatter the rest over the fruit. It slices more neatly than most crisps, but still eats like a spoonable, syrupy, golden-edged crumble. If you love fruity bakes, you might also like my brown butter strawberry peach pie—different vibe, same “fruit-first” payoff.

Why You’ll Love This Recipe

The topping does double duty: half becomes a buttery base, so the fruit isn’t sitting directly on the pan.
Peaches and strawberries bake into a bright, jammy layer—sweet, but not one-note.
The cornstarch-thickened syrup sets the fruit juices so you don’t end up with a watery puddle.
Old-fashioned oats give the crumble real texture (you’ll hear a soft crunch when you cut in).
It’s a 9×9 pan dessert that’s easy to portion—clean squares while warm, softer spoonfuls once it sits.
The ingredient list is short and familiar; it’s the kind of bake you can pull off without a special trip.

The Story Behind This Recipe

I started making this when I wanted a crisp that didn’t feel loose and messy in the pan—something that could still be scooped, but also cut into tidy pieces for sharing. Pressing part of the oat mixture into the bottom was the small change that did it, and the simple brown sugar–cornstarch syrup keeps the peaches and strawberries glossy instead of soupy (similar to what I aim for in my apple crisp with oats).

What It Tastes Like

It’s warmly sweet with that unmistakable brown sugar aroma, and the fruit tastes “baked” in the best way—peaches get mellow and floral, strawberries turn deeper and jammy. The topping is buttery and toasty, crisp at the edges and more cookie-like where it meets the syrupy fruit. Overall it’s rich enough to feel like dessert, but still bright from the strawberries.

Ingredients You’ll Need

Peaches and strawberries are the whole point here, so slice them evenly so they bake at the same pace. Old-fashioned oats (not quick oats) give the topping a hearty crunch, while flour helps it clump into real crumbles instead of melting into a thin layer. Cornstarch is what thickens the fruit juices into a spoon-coating syrup that sets up as the crisp cools.

2 ½ cups peeled and sliced peaches (about 3 peaches)
1 cup sliced strawberries
½ cup old-fashioned oats
½ cup brown sugar
⅓ cup salted butter (melted)
⅔ cup flour
3 teaspoons cornstarch
⅓ cup water

How to Make Strawberry Peach Crisp

Heat the oven. Preheat your oven to 350°F (175°C). Grease a 9×9-inch baking pan so the bottom “crust” lifts cleanly.
Make the crumble mixture. In a mixing bowl, combine the old-fashioned oats, brown sugar, flour, and cinnamon. Pour in the melted salted butter and mix until you have moist, sandy clumps. You’re looking for a mixture that holds together when you squeeze it, but still breaks into crumbs.
Press in the base. Sprinkle half of the crumb mixture into the prepared pan and press it into an even layer. It doesn’t have to be rock-hard—just lightly packed so it bakes into a soft, structured base.
Add the fruit. Layer the sliced peaches and sliced strawberries evenly over the base. Try to spread them to the corners so every piece gets fruit and crumble.
Cook the thickening syrup. In a small saucepan, combine brown sugar, cornstarch, salt, and water. Cook over medium heat, stirring constantly, until it thickens from cloudy to glossy and coats the spoon. This happens fairly quickly once it starts—don’t walk away.
Finish the syrup and pour. Stir in the vanilla extract, then pour the syrup evenly over the fruit. Aim for a light, even drizzle across the surface rather than dumping it in one spot.
Top and bake. Scatter the remaining crumb mixture over the fruit. Bake for about 35 minutes, until the top is golden brown and you can see some bubbling around the edges.
Cool before cutting. Let it sit for at least 15–20 minutes. Right out of the oven the filling will be looser; as it cools, it thickens and slices more cleanly.

Tips for Best Results

Slice the peaches consistently. Thin, even slices bake tender at the same time as the strawberries; thick chunks can stay firm while the topping browns.
Mix the crumble just until clumpy. Once the butter is evenly absorbed and you have pea-size to walnut-size crumbs, stop—overmixing can make it pasty.
Cook the syrup until truly thick. If it still looks watery in the pan, the crisp is more likely to bake up runny. You want a spoon-coating consistency before you pour it on.
Watch the edges at the 30-minute mark. When the corners are deep golden and you see gentle bubbling, you’re close; baking far past that can dry out the fruit.
Cool for cleaner portions. Warm is delicious, but letting it rest helps the cornstarch do its job so you get neat squares instead of a puddle (a trick that also helps with my more classic apple crisp).

Variations and Substitutions

Swap the fruit ratio. Keep the total fruit amount similar, but lean more peach-forward or strawberry-forward depending on what you have.
Make it more “bar-like.” Press the bottom layer a little more firmly so it bakes into a sturdier base before adding fruit and topping.
Skip peeling if you like. Peach skins soften as they bake; the texture will be slightly more rustic.

How to Serve It

Serve it warm so the peaches are extra soft and the strawberry layer tastes almost like jam. I love it in shallow bowls where you can catch the syrup, but it also cuts into satisfying squares once it cools a bit. If you’re putting together a fruit-dessert spread, it pairs nicely alongside something flaky like my strawberry danish pastry for contrast.

How to Store It

Cover the pan and refrigerate leftovers. The topping will soften in the fridge (that’s normal for a fruit crisp), but the flavors deepen nicely overnight. Rewarm portions so the fruit loosens and the crumble perks back up. For make-ahead, you can bake it earlier in the day and let it sit at cool room temperature for a few hours before serving—just know it slices cleanest once it’s had a little time to set.

Final Thoughts

This is the kind of bake that feels effortless but looks intentional: a golden oat top, a glossy fruit layer, and a soft, buttery base that holds everything together. If you’ve got ripe peaches and a carton of strawberries, it’s a very good way to use them.
