Ingredients
You’ll need two simple components here: the fruit filling and the streusel topping. Everything is measured out below in both cups and grams for easy prep no matter what system you use.
For the fruit filling:
- 4 cups fresh peaches, peeled and sliced (about 5 medium peaches / 600g)
- 2 cups fresh blueberries (300g)
- 1/3 cup granulated sugar (65g)
- 1 tablespoon lemon juice, freshly squeezed
- 2 tablespoons cornstarch
- 1 teaspoon vanilla extract
- 1/4 teaspoon ground cinnamon
For the streusel topping:
- 1 cup old-fashioned rolled oats (90g)
- 3/4 cup all-purpose flour (95g)
- 2/3 cup packed brown sugar (145g)
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon salt
- 1/2 cup cold unsalted butter, cubed (115g)
Kitchen Equipment Needed
Nothing exotic here. A solid baking dish and a couple of mixing bowls will get you through this recipe from start to finish.
- 9×13 inch baking dish, or a 9-inch cast iron skillet
- Large mixing bowl for the fruit
- Medium mixing bowl for the streusel topping
- Pastry cutter or your fingers for cutting in the butter
- Measuring cups and spoons
- Cutting board and sharp knife for slicing peaches
Recommended Products for This Recipe
A few good tools genuinely make this crisp easier to pull off and give you better results. Here are the ones worth having in your kitchen.
1. Lodge Cast Iron Skillet
A cast iron skillet holds heat evenly and gives the topping a deep golden crust that’s hard to get in a regular glass dish. It also goes straight from oven to table, which makes serving warm crisp effortless.
2. Pyrex 9×13 Baking Dish
This classic glass baking dish is a reliable option if you don’t have cast iron, and it lets you see the fruit bubbling around the edges as it bakes. It’s also dishwasher safe, which makes cleanup simple after a baked-on fruit dessert.
3. OXO Good Grips Pastry Blender
Cutting cold butter into the streusel by hand can get messy fast. A pastry blender cuts through butter quickly and keeps the topping cool, which is what gives you those crisp, distinct crumbles instead of a paste.
4. Microplane Zester and Juicer
A good citrus juicer gets every last drop of lemon juice out with no seeds ending up in your filling. Fresh lemon juice makes a real difference here since it balances the sweetness of the fruit.
Step-by-Step Instructions
1. Preheat the Oven and Prep Your Dish
- Preheat your oven to 375°F (190°C).
- Lightly grease your 9×13 baking dish or cast iron skillet with butter or nonstick spray.
- Set the dish aside while you prepare the fruit and topping.
2. Prepare the Fruit Filling
- Peel and slice the peaches into 1/2 inch thick wedges, then place them in a large mixing bowl.
- Add the blueberries directly to the bowl with the peaches, rinsing them beforehand and patting them dry.
- Sprinkle the granulated sugar, cornstarch, and cinnamon over the fruit.
- Add the lemon juice and vanilla extract.
- Gently toss everything together with a large spoon until the fruit is evenly coated. Be careful not to mash the blueberries.
- Let the mixture sit for 5 minutes so the cornstarch starts to draw out some juice, which helps the filling thicken as it bakes.
3. Make the Streusel Topping
- In a medium mixing bowl, combine the rolled oats, flour, brown sugar, cinnamon, and salt.
- Whisk these dry ingredients together until evenly combined.
- Add the cold, cubed butter to the bowl.
- Using a pastry cutter, fork, or your fingertips, work the butter into the dry mixture until it forms coarse, pea-sized crumbles. Cold butter is key here, since it’s what creates those crisp little clusters on top rather than a flat, cakey layer.
4. Assemble the Crisp
- Pour the fruit filling into your prepared baking dish, spreading it into an even layer.
- Sprinkle the streusel topping evenly over the fruit, making sure to cover the surface completely so no fruit is exposed to direct heat, which helps prevent it from drying out.
- Gently press the topping down with the back of a spoon so it adheres slightly to the fruit underneath.
5. Bake the Crisp
- Place the dish in the preheated oven on the center rack.
- Bake for 35 to 40 minutes, until the topping is golden brown and the fruit filling is bubbling around the edges.
- If the topping starts browning too quickly, loosely tent the dish with foil for the last 10 minutes of baking.
- Remove from the oven once the filling looks thick and glossy rather than watery.
6. Cool and Serve
- Let the crisp rest for 10 to 15 minutes before serving. This resting time allows the cornstarch to finish thickening the filling, so your slices hold together instead of running.
- Serve warm, scooped into bowls, with a generous scoop of vanilla ice cream if you like.
Tips for Success
A few small details make a big difference between an average crisp and a great one. Keep these in mind as you bake.
- Use cold butter straight from the fridge for the streusel so it stays in distinct crumbles.
- Don’t skip the cornstarch. It’s what keeps your filling from turning into fruit soup.
- If your peaches aren’t very sweet, add an extra tablespoon of sugar to the filling.
- Let the crisp rest before serving so the filling has time to set.
- Use a rimmed baking dish, since the fruit filling can bubble over as it bakes.
Serving Suggestions
This crisp is delicious on its own, but a few simple additions turn it into a full dessert spread. Warm crisp against something cold and creamy is really where the magic happens.
- A scoop of vanilla ice cream
- A dollop of freshly whipped cream
- A drizzle of caramel sauce
- A sprinkle of toasted almonds or pecans on top
- A cup of coffee or a glass of iced tea alongside it
Variations to Try
Once you’ve made the basic version, this crisp is easy to riff on depending on what’s in season or in your pantry. Small swaps can completely change the flavor profile.
- Swap the peaches for nectarines or plums for a different stone fruit twist.
- Add chopped pecans or walnuts to the streusel for extra crunch.
- Use frozen peaches and blueberries when fresh fruit is out of season, no need to thaw first.
- Stir in a handful of raspberries or blackberries for a mixed berry version.
- Add a splash of almond extract to the topping for a nuttier flavor.
Storage and Reheating
Leftover crisp keeps well for a few days, which makes it a great make-ahead dessert for gatherings. Here’s how to store and reheat it properly.
- Store leftovers covered in the refrigerator for up to 4 days.
- Reheat individual portions in the microwave for 30 to 45 seconds.
- To re-crisp the topping, reheat in a 350°F oven for about 10 minutes.
- Freeze baked and cooled crisp in an airtight container for up to 3 months.
- Thaw frozen crisp overnight in the refrigerator before reheating in the oven.

Health Benefits of Key Ingredients
Beyond being delicious, several ingredients in this crisp bring real nutritional value to the table. It’s a dessert that at least offers a little more than empty sugar.
Peaches and blueberries are both packed with vitamins and antioxidants that support overall health. Oats add fiber and help make the topping more filling than a typical pastry crust.
- Peaches provide vitamin C and vitamin A
- Blueberries are rich in antioxidants, particularly anthocyanins
- Oats offer fiber that supports digestion
- Cinnamon has natural anti-inflammatory properties
- Lemon juice adds a boost of vitamin C
Frequently Asked Questions
1. Can I use frozen fruit instead of fresh?
Yes, frozen peaches and blueberries work well in this recipe. There’s no need to thaw them first, just add an extra 5 to 10 minutes to the baking time since frozen fruit releases more liquid as it cooks.
2. Why is my crisp filling too runny?
This usually means the fruit needed more time to bake or more cornstarch to properly thicken. Letting the crisp rest for at least 10 minutes after baking also helps the filling set up properly.
3. Can I make this crisp ahead of time?
You can assemble the unbaked crisp up to a day in advance and refrigerate it covered. Bake it fresh when you’re ready to serve, adding a few extra minutes to the bake time since it will start out cold.
4. Do I need to peel the peaches?
Peeling is optional and mostly a matter of texture preference. The skins soften significantly during baking, so many people skip peeling entirely to save time.
5. What’s the difference between a crisp and a cobbler?
A crisp has a streusel-style topping made with oats, flour, and butter, while a cobbler is topped with biscuit-like dough or dumplings. Both are baked fruit desserts, but the topping is what sets them apart.
