This peach crumble recipe is my go-to dessert throughout the summer. Sweet, jammy peaches bubble beneath a thick oat crumb topping that browns beautifully. It works with fresh, frozen, or canned peaches—few easy techniques keep the filling glossy instead of runny and prevent the topping from getting soggy.
Peach Crumble Recipe Ingredients
The ingredients are separated into two short lists: the peach filling and the oat crumble topping.
Peach Filling Ingredients
- Fresh peaches: sliced; peel if you prefer a smoother filling.
- Granulated sugar
- Cornstarch: essential to thicken the fruit juices as the crumble cools so the topping stays crisp.
- Lemon juice: brightens the fruit flavor.
- Vanilla extract
- Salt
Oat Crumb Topping Ingredients
- All-purpose flour
- Old-fashioned rolled oats: use old-fashioned, not quick or instant, so the oats stay chewy and textural.
- Brown sugar: adds caramel notes that complement the peaches.
- Ground cinnamon
- Kosher salt
- Unsalted butter: cut into small pieces and worked in until damp, pea-sized clumps form.
Exact quantities are listed in the recipe card further down.
Variations and Substitutions
This crumble accepts substitutions easily—use what you have on hand.
- Blueberry-peach crumble: stir a cup of fresh or frozen blueberries into the filling.
- Canned peaches: drain well and reduce the granulated sugar slightly to account for added syrup.
- Frozen peaches: add them frozen to the dish and increase baking time by about 10 minutes.
- Gluten-free: substitute a 1:1 gluten-free flour blend and certified gluten-free oats.
- Nutty topping: fold in 1/2 cup chopped pecans or sliced almonds for crunch.
- Other fruit: pears, plums, or mixed stone fruit can be used with the same method.
Recommended Tools
Simple tools are all you need—part of what makes this dessert so easy.
- 2-quart baking dish: an 8×8 square or a 9-inch round works well.
- Large mixing bowl: for tossing the peaches with the thickener and sugar.
- Medium bowl: for combining the topping ingredients.
- Paring knife or chef’s knife: for slicing peaches.
- Aluminum foil: to tent the crumble if the top is browning too quickly during baking.
How to Make My Peach Crumble Recipe: An Easy Guide
The method has three straightforward stages: toss the fruit, make the topping, and bake until golden and bubbling. Total time is about an hour from start to finish.
Toss the Peaches
Preheat the oven to 375°F (190°C) and lightly butter a 2-quart baking dish. Slice the peaches into a large bowl, then add the granulated sugar, cornstarch, lemon juice, vanilla, and a pinch of salt. Toss gently until every slice is lightly coated and there’s no visible dry cornstarch.
Make the Oat Crumb Topping
In a medium bowl, whisk together the flour, old-fashioned oats, brown sugar, cinnamon, and salt. Add the cold, cubed unsalted butter and work it in with your fingers until the mixture forms damp, pea-sized clumps. The topping should be evenly moistened with no dry flour remaining.
Assemble and Bake Until Golden Brown
Spread the peach mixture evenly in the prepared dish and scatter the oat topping over the fruit, breaking up any very large clumps. Bake for 40 to 45 minutes, until the filling bubbles around the edges and the topping is deeply golden. If the topping is browning too quickly, loosely tent with foil after about 25 minutes. Let the crumble rest for 10 minutes after baking so the filling thickens and sets before serving.
5 Common Mistakes to Avoid
Prevent these common errors for the best result:
- Skipping the cornstarch: without it the juices remain thin and the topping can become soggy.
- Using underripe fruit: overly firm peaches won’t soften or develop flavor even after a long bake.
- Overworking the topping: keep the clumps pea-sized—don’t press it into a dough.
- Removing too early: wait for the filling to bubble at the edges, not just for a golden top.
- Serving immediately: let the crumble rest 10 minutes so the filling sets and slices cleanly.
Make Ahead and Storage
This crumble stores well and the topping crisps up again when reheated in the oven.
Storing Leftovers
- Room temperature: loosely covered for up to 1 day.
- Refrigerator: covered for up to 4 days; leave the cover loose to avoid trapping steam.
Freezing
- Baked: cool completely, wrap tightly, and freeze for up to 3 months.
- Unbaked: assemble in the baking dish, wrap, and freeze; bake from frozen, adding 15–20 minutes to the bake time.
Reheating Leftovers
- Oven: 350°F (175°C) for about 15 minutes restores the crisp topping.
- Microwave: 30 seconds for a single portion, though the topping will soften.
- Cold: tasty straight from the fridge with a dollop of yogurt.
What to Serve with This Peach Crumble
- Vanilla ice cream: the classic choice—melts into the warm fruit.
- Cold heavy cream: simply poured over the top for a rich contrast.
- Greek yogurt: a tangy option that turns leftovers into an easy breakfast.
- Complementary fruit: serve with additional fresh stone fruit for a summer spread.
Tips for the Best Easy Peach Crumble
Small adjustments make a big difference:
- Choose ripe but firm peaches: peaches that yield slightly at the seam hold their shape during baking. If fruit is very juicy, add an extra teaspoon or two of cornstarch.
- Keep the skins on: they soften and add color to the filling; peeling is optional.
- Use old-fashioned oats: quick oats become pasty and lose texture.
- Tent, don’t seal: loosely tent foil to slow browning without steaming the topping.
- Allow a short rest: cornstarch thickens as it cools—wait 10 minutes before serving.
Frequently Asked Questions
Quick answers to common questions about this recipe.
A crisp includes oats in the topping while a traditional crumble is made with flour, sugar, and butter. This recipe uses oats, so it fits both descriptions depending on terminology.
No. A cobbler uses a soft biscuit or cake-like topping, while a crumble has a dry, sandy crumb topping that bakes crisp and golden.
No. Peach skins soften completely during baking and add color to the filling. Peel only if you prefer a smoother texture.
Yes. Drain canned peaches thoroughly and reduce the added sugar slightly since canned fruit can be sweetened. Keep the cornstarch amount the same.
More Baking and Storage FAQ
Yes. Use them frozen (don’t thaw), add about 10 minutes to the bake time, and watch for bubbling at the edges to know it’s done.
Runny filling usually means it was served too soon or the cornstarch was missed. Cornstarch thickens as the filling cools—allow a 10-minute rest. Very juicy fruit may need a little extra cornstarch.
Yes. Assemble in the baking dish, cover, and refrigerate up to one day before baking. You can also freeze it unbaked and bake from frozen, adding extra time.
A 2-quart baking dish—an 8×8 inch square, an 11×7 inch rectangle, or a 9-inch round about 2 inches deep—is ideal so the filling has room to bubble without overflowing.
