Ingredients List
Here’s everything you’ll need to make this delicious Peach and Blueberry Crisp with Oat Topping:
- 4 cups fresh peaches, peeled and sliced (about 4-5 medium peaches)
- 2 cups fresh blueberries (or frozen, if out of season)
- 1/2 cup granulated sugar (or coconut sugar for a healthier option)
- 1 tbsp lemon juice (to enhance the fruit’s natural flavors)
- 1 tsp vanilla extract
- 1 tbsp cornstarch (or arrowroot powder for thickening)
- 1 cup old-fashioned rolled oats (not instant)
- 1/2 cup all-purpose flour (or almond flour for gluten-free)
- 1/2 cup brown sugar, packed
- 1/2 tsp ground cinnamon
- 1/4 tsp salt
- 1/2 cup unsalted butter, cold and cubed (or coconut oil for vegan)
Timing
This Peach and Blueberry Crisp with Oat Topping comes together in just 55 minutes—that’s 15 minutes of prep and 40 minutes of baking. Compared to traditional pies, which can take up to 90 minutes, this crisp is a time-saving dessert that doesn’t skimp on flavor.
Step-by-Step Instructions
Step 1: Prepare the Fruit Filling
In a large bowl, toss the sliced peaches and blueberries with granulated sugar, lemon juice, vanilla extract, and cornstarch. Mix gently until the fruit is evenly coated. Let it sit for 10 minutes to allow the flavors to meld.
Step 2: Make the Oat Topping
In a separate bowl, combine the oats, flour, brown sugar, cinnamon, and salt. Add the cold cubed butter and use your fingers or a pastry cutter to work it into the dry ingredients until the mixture resembles coarse crumbs.
Step 3: Assemble and Bake
Preheat your oven to 375°F (190°C). Transfer the fruit mixture to a greased 9×9-inch baking dish. Sprinkle the oat topping evenly over the fruit. Bake for 35-40 minutes, or until the topping is golden brown and the fruit filling is bubbling.
Step 4: Cool and Serve
Let the crisp cool for 10 minutes before serving. This allows the juices to thicken slightly. Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream.

Common Mistakes to Avoid
To ensure your Peach and Blueberry Crisp with Oat Topping turns out perfectly, avoid these pitfalls:
- Overmixing the topping: This can make it dense instead of crumbly. Mix just until combined.
- Using overly ripe fruit: Too-soft peaches can turn mushy. Opt for slightly firm fruit.
- Skipping the cornstarch: Without it, the filling may be too runny.
- Baking at the wrong temperature: Too high, and the topping burns; too low, and it won’t crisp up.
Storing Tips for the Recipe
Here’s how to keep your crisp fresh:
- Refrigerate: Store leftovers in an airtight container for up to 3 days.
- Freeze: Wrap tightly and freeze for up to 2 months. Reheat in the oven at 350°F until warm.
- Reheat: Warm individual servings in the microwave or oven for best texture.
