Silas ate four servings of this in one sitting. Four.
I watched him go back for seconds, then thirds, then finally just brought the whole dish to the couch with a spoon and gave up on pretending he was going to stop. He didn’t even deny it. He just said “this is a problem” and kept eating.
That’s the kind of peach crisp we’re talking about here.
This is the old fashioned version. No fancy add-ins, no weird shortcuts, no ingredients you’ve never heard of. Just ripe peaches, a buttery oat topping, and a little cinnamon doing exactly what cinnamon does best.
It’s the recipe my grandma made every August when the peaches finally got soft and sweet enough to bruise if you looked at them wrong. I’ve made a few small tweaks over the years, but honestly, not many. Some things don’t need fixing.
Let’s get into it.
Why This Recipe Works
A good peach crisp comes down to two things. Juicy filling, crunchy topping. That’s it. That’s the whole equation.
The trick is making sure neither one ruins the other.
Cornstarch thickens the peach juices just enough so you get syrup, not soup. Old fashioned rolled oats (not quick oats, we’ll talk about why) give you that thick, craggy topping that holds its crunch even after a scoop of vanilla ice cream melts all over it.
And brown sugar in the topping instead of white sugar adds this deep, almost caramel flavor that makes people ask what your secret is. Your secret is brown sugar. That’s it. You can tell them if you want.
What You’ll Need
For the Peach Filling
| Ingredient | Amount |
|---|---|
| Fresh peaches, peeled and sliced | 6 cups (about 8 medium peaches) |
| Granulated sugar | 1/3 cup |

| Lemon juice | 1 tablespoon |
| Ground cinnamon | 1/2 teaspoon |
| Ground nutmeg | 1/4 teaspoon |
| Vanilla extract | 1 teaspoon |
| Salt | 1/8 teaspoon |
For the Crisp Topping
| Ingredient | Amount |
|---|---|
| Old fashioned rolled oats | 1 cup |
| All-purpose flour | 3/4 cup |
| Brown sugar, packed | 3/4 cup |
| Ground cinnamon | 1/2 teaspoon |
| Salt | 1/4 teaspoon |
| Unsalted butter, cold and cubed | 1/2 cup (1 stick) |
| Chopped pecans (optional) | 1/2 cup |
Tools You’ll Need
- 9×13 inch baking dish
- Large mixing bowl
- Medium mixing bowl
- Pastry cutter or two forks
- Sharp knife and cutting board
- Measuring cups and spoons
- Peeler
Pro Tips
- Don’t skip peeling the peaches. I know it’s tempting to leave the skins on and call it rustic. But the skins get chewy and slightly bitter once baked, and it’s just not worth the shortcut here.
- Toss your peaches in lemon juice first. It stops them from browning while you prep everything else, and it brightens up the whole filling so it doesn’t taste one-note sweet.
- Keep your butter cold. Cold butter is the whole reason the topping turns out clumpy and crisp instead of flat and greasy. If your kitchen is warm, pop the cubed butter in the freezer for 5 minutes before you start mixing.
- Use your fingers for the topping, not just a fork. Rub the butter into the dry mix with your fingertips until it looks like wet sand with some pea-sized chunks. That texture is what gives you those crispy little clusters on top.
- Let it rest before serving. I know, I know. But 10 minutes out of the oven lets the filling set up so it doesn’t run all over the plate. Your patience will be rewarded.
How to Make Old Fashioned Peach Crisp
Step 1: Prep the Oven and Dish
Preheat your oven to 350°F. Lightly butter your 9×13 baking dish or spray it with nonstick spray.
Step 2: Make the Peach Filling
In your large mixing bowl, combine the sliced peaches, granulated sugar, cornstarch, lemon juice, cinnamon, nutmeg, vanilla, and salt.
Toss gently until every peach slice is coated. Pour the mixture into your prepared baking dish and spread it into an even layer.
Step 3: Make the Crisp Topping
In your medium bowl, whisk together the oats, flour, brown sugar, cinnamon, and salt.
Add the cold, cubed butter. Using a pastry cutter (or your fingers, see Pro Tip #4), work the butter into the dry ingredients until it forms coarse, clumpy crumbs.
Stir in the pecans if you’re using them.
Step 4: Assemble
Sprinkle the topping evenly over the peaches. Don’t press it down. You want it loose and craggy so it bakes up crunchy in every direction.
Step 5: Bake
Bake for 40 to 45 minutes, until the topping is deep golden brown and the peach filling is bubbling up around the edges.
If the topping starts browning too fast, loosely tent it with foil for the last 10 minutes.
Step 6: Cool and Serve
Let the crisp rest for at least 10 minutes before serving. It’ll still be warm, just not lava hot.
Serve as is, or with a scoop of vanilla ice cream on top, because obviously.
Substitutions and Variations
| Original | Swap | Notes |
|---|---|---|
| Fresh peaches | Frozen peaches | Thaw and drain well first, or the filling turns watery |
| Rolled oats | Quick oats | Works in a pinch, but topping will be less chunky |
| Pecans | Walnuts or sliced almonds | Any nut you like works here |
| All-purpose flour | Gluten-free 1:1 flour blend | Keep everything else the same |
| Brown sugar | Coconut sugar | Slightly less sweet, still delicious |
| Butter | Vegan butter stick | Use a solid stick, not the tub kind |
Want a little extra warmth? Add a pinch of ground ginger or cardamom to the filling. It’s not traditional, but it’s really good.
Make Ahead Tips
You can prep this in stages if you’re feeding a crowd or just want to get ahead of it.
- The topping can be mixed and stored in the fridge for up to 3 days, or frozen for up to a month.
- The peach filling can be sliced and tossed with the sugar mixture up to a day ahead. Keep it covered in the fridge.
- Assembled but unbaked, the whole thing can sit in the fridge for a few hours before baking. Just add 5 extra minutes to the bake time since it’ll be starting cold.
I don’t recommend baking it fully ahead of time and reheating. The topping loses some of its crunch that way.

Pairing Suggestions
This crisp is rich enough to stand on its own, but a few things take it up a level:
- A scoop of good vanilla bean ice cream, obviously
- A dollop of lightly sweetened whipped cream
- A drizzle of caramel sauce if you’re feeling extra
- A cup of coffee or chai if you’re serving this for brunch instead of dessert
Storage and Reheating
Room temperature: Fine for a few hours if you’re serving it the same day.
Refrigerator: Store covered for up to 5 days. The topping softens a bit, but it still tastes great.
Freezer: Freeze in an airtight container for up to 3 months. Thaw in the fridge overnight before reheating.
To reheat: Pop individual portions in the microwave for 30 to 45 seconds, or warm the whole dish in a 300°F oven for about 15 minutes to bring back some of that crunch.
FAQ
Can I use canned peaches instead of fresh?
You can, but drain them really well first and cut back the sugar in the filling by half, since canned peaches are usually packed in syrup.
Why is my crisp soggy on top?
Usually it means the butter was too warm when you mixed the topping, or the dish sat too long before serving and the steam softened everything. Cold butter and a short cooling rest fix both problems.
Can I double this recipe?
Yes. Use a 9×13 dish for a single batch, or split a double batch between two dishes. Don’t try to cram it all into one pan or the middle won’t cook through properly.
Do I have to peel the peaches?
Technically no, but I really recommend it. See Pro Tip #1 for why.
Can I make this in a smaller dish?
An 8×8 dish works if you’re making a half batch. Bake time will be closer to 30 to 35 minutes.
Wrapping Up
This is the kind of dessert that doesn’t need to be dressed up or explained. You make it, it fills the kitchen with cinnamon and butter, and everyone finds a reason to hover near the oven while it bakes.
If you make this one, I’d love to know how it turned out. Drop a comment below and tell me if you added your own twist, or if Silas would approve of your topping-to-filling ratio. He has opinions.
