Ingredients
  

  • 5 cups sliced fresh peaches (peeled or unpeeled) about 1.75 lb / 800g, preferably California peaches
  • 1/4 cup all-purpose flour, spooned and leveled 31g
  • 1/2 cup granulated sugar 100g
  • 1/8 teaspoon fine salt
  • 1 tablespoon fresh Meyer lemon juice
  • 1/2 teaspoon pure vanilla extract
  • 1/2 cup packed light or dark brown sugar 100g
  • 2/3 cup all-purpose flour 84g
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon fine salt
  • 1/2 cup unsalted butter, very cold, cut into cubes 1 stick / 113g
  • 2/3 cup old-fashioned rolled oats or quick oats 57g
  • 2/3 cup chopped or halved unsalted pecans 95g; optional

Method
 

  1. Preheat the oven to 350°F (177°C). Lightly grease a deep 9-inch pie dish, 9-inch square pan, 10-inch cast iron skillet, or another 2 to 2.5 quart baking dish; set aside.
  2. In a large bowl, combine the sliced peaches, 1/4 cup flour, granulated sugar, 1/8 teaspoon salt, lemon juice, and vanilla. Toss gently until the fruit is evenly coated, then transfer to the prepared dish.
  3. In a separate bowl, whisk the brown sugar, remaining 2/3 cup flour, cinnamon, and 1/4 teaspoon salt. Cut in the cold butter with a pastry cutter or two forks until the mixture forms coarse crumbs. Fold in the oats and pecans, then sprinkle the streusel evenly over the peach filling.
  4. Bake for 45 to 50 minutes, until the topping is golden brown and the juices bubble around the edges. Remove from the oven and cool on a wire rack for a few minutes before serving warm. The crisp can also be served at room temperature or chilled.
  5. Cover any leftovers and refrigerate for up to 5 days.

Notes

Use ripe but slightly firm peaches so they hold their shape during baking.
Omit the pecans or swap them for extra oats if you want a nut-free crisp.
Assemble the dish a day ahead and keep it covered in the fridge; add 5 to 10 minutes to the bake time if baking cold.
Let the crisp rest for 10 minutes after baking so the juices can settle.
For a gluten-free version, use a 1-to-1 gluten-free flour blend and certified gluten-free oats.
Serve warm with vanilla ice cream, whipped cream, or a dollop of creme fraiche.
Store leftovers covered in the fridge for up to 5 days.

Why You’ll Love This Peach Crisp

It starts with a bag of peaches on the counter. Maybe you grabbed them at the farmers market, or maybe they came home from Vons in a paper sack. Either way, they’re ripening fast, and you can smell them from across the kitchen, that sweet, floral, almost-honey scent that means it’s August in California.

This easy peach crisp is what I make with those peaches. It’s the summer dessert I turn to again and again because it’s forgiving, it’s fast, and it makes the whole house smell incredible. You don’t need pastry skills. You don’t need fancy equipment. Just a bowl, a baking dish, and about 15 minutes of hands-on time. What makes this easy peach crisp so special? Honestly, the butter. Cold butter creates that shaggy, sandy streusel that bakes up golden and crackly.

Here’s what you get for your effort:

  • Juicy, jammy peach filling that’s thick enough to cling to a spoon, never watery
  • A buttery brown sugar oat topping with toasted pecans, crunchy on top and slightly chewy underneath
  • One-bowl simplicity that works for weeknights and cookouts alike
  • Make-ahead flexibility so you can pull it together when you have a minute, then bake it right before serving

And if you’re worried about wasting expensive farmers market peaches on a recipe that flops, don’t be. This one forgives. The first time I made this easy peach crisp, I skipped the thickener and my filling was basically peach soup. Still delicious, spoon it over ice cream and call it a compote, but trust me, add the flour to the filling. It makes all the difference.

This easy peach crisp is proof you don’t need a complicated recipe to impress people. It might just become your signature summer dessert, the one everyone asks for by name at the Fourth of July cookout.

Peach Crisp Ingredients

peach crisp - main ingredients

This easy peach crisp has a short, honest ingredient list. Nothing exotic, nothing hard to find. Let me walk you through what matters and why.

  • Fresh peaches (5 cups sliced). About 1.75 pounds. Ripe but slightly firm is the sweet spot. More on that below.
  • All-purpose flour. Does double duty here. It thickens the peachy juices in the filling, and it gives the streusel structure.
  • Granulated sugar. Draws out the peach juices and balances the tartness.
  • Meyer lemon juice. Just a tablespoon. It wakes up the peach flavor and keeps things bright.
  • Vanilla extract. A little warmth in the background.
  • Brown sugar. For the topping. Light or dark both work, dark gives more molasses depth.
  • Cinnamon and salt. The flavor backbone of the streusel. That tiny pinch of salt in the filling makes the sweetness pop.
  • Unsalted butter, very cold. The most important ingredient in the topping. Cold butter creates steam pockets, which is what makes a streusel crisp instead of dense.
  • Old-fashioned rolled oats. They hold their shape and stay crunchy. Quick oats work but turn softer, so I always reach for the old-fashioned ones.
  • Pecans. Optional, but they toast up beautifully and add such a nice crunch.

See what I mean? Nothing weird. You probably have most of this already, which is exactly why this easy peach crisp works so well on a whim.

Fresh or Canned Peaches?

This is the question I get most, so let’s settle it. The honest answer: fresh peaches are best. But frozen and canned both work in a pinch. Here’s the tradeoff.

Fresh peaches are at their peak right now. August brings perfect fruit, and a ripe, juicy peach barely needs any help. The best easy peach crisp starts with fruit that smells like a peach should, floral and sweet. If you’re at the farmers market and they’re practically begging to come home with you, grab 5 cups worth and go.

Frozen peaches are a solid year-round option. Thaw them first, drain off the liquid, and pat them dry. This step matters. Frozen fruit releases a lot of water as it thaws, and you don’t want that pooling in your crisp. Add about 5 minutes to the bake time since the fruit starts colder.

Canned peaches work too. Use about 2 (15-ounce) cans, drained very well. Canned peaches are softer and sweeter, so you can cut the sugar in the filling by a tablespoon or two. Pat them dry before adding to the dish.

Whichever route you take, this easy peach crisp will still come together. You might just need to adjust the bake time slightly, and that’s fine. Bubbling edges and a golden topping tell you when it’s done, not the clock.

How to Make This Easy Peach Crisp

Let’s walk through making an easy peach crisp from start to finish. The full recipe is in the card above, but here’s the reasoning behind each step so you know what to expect.

Prepare the Peach Filling

Peeling is optional, and I honestly don’t bother most of the time. Peach skins are thin, and they soften right up during baking. If you do want to peel them, drop the peaches in boiling water for 30 seconds, then into an ice bath. The skins basically slip right off.

Slice your peaches into even pieces, about 1/4 to 1/2 inch thick, and toss them with the flour, sugar, salt, lemon juice, and vanilla. The flour is the key here. It coats the peaches and thickens the juices as they bake, giving you that jammy, spoonable filling instead of a watery one.

Step 1: Slicing ripe peaches and tossing them with flour, sugar, lemon juice, and vanilla until evenly coated, glistening fruit in a large bowl

Taste a slice as you go. If your peaches are bursting sweet, you can cut the sugar a bit. If they’re a little tart, add an extra spoonful. The recipe is a starting point, not a rule.

Make the Oat Streusel

This is where the magic happens. Whisk together the brown sugar, flour, cinnamon, and salt, then cut in the cold butter using a pastry cutter or two forks. You want coarse crumbs, some pebbly pieces about the size of peas, some smaller sand-like bits. Don’t overdo it.

Fold in the oats and pecans last. This matters. If you add them before cutting in the butter, they get broken down and lose their texture. Fold them gently at the end so they stay whole and crunchy.

Step 2: Cutting cold butter cubes into the brown sugar, flour, and cinnamon mixture with a pastry cutter until coarse shaggy crumbs form

Yes, it looks like a lot of topping. That’s intentional. A generous layer of streusel means every spoonful gets some crunch, and part of it bakes down into the peachy juices, which is honestly the best part.

Assemble and Bake the Crisp

Spoon the peach filling into a deep 9-inch pie dish, a square pan, or a 10-inch cast iron skillet. Then sprinkle the streusel evenly over the top. Don’t press it down. Just let it fall naturally and cover as much fruit as you can.

Step 3: Sprinkling the golden oat-pecan streusel clumps evenly over the peach filling in a cream ceramic pie dish before baking

A cast iron skillet is great here because it holds heat well and the edges develop that nice caramelized crust. But honestly, any 2 to 2.5 quart baking dish works. Use what you have.

Pop it in a 350°F oven for 45 to 50 minutes. You’re looking for two things: a deep golden brown topping, and thick juice bubbling up around the edges. That bubbling tells you the filling has thickened.

Step 4: Pulling the fully baked crisp from the oven, deep golden brown crackly topping with thick jammy peach juice bubbling at the edges

Here’s where patience pays off. Let the crisp rest for about 10 minutes after it comes out. The juices need time to settle. If you dig in right away, the filling will run everywhere. Ten minutes, and it’ll hold its shape, warm and jammy. The hardest part of this recipe is honestly the waiting. Your kitchen will smell like brown sugar and cinnamon, and the crisp will be bubbling and crackling on the counter. Set a timer. Resist the urge to peek.

Tips for the Best Peach Crisp

After making this easy peach crisp more times than I can count, here are the things that actually matter:

  • Choose ripe but slightly firm peaches. You want fruit that gives a little when pressed but holds its shape. If your peaches are still hard, let them sit in a paper bag for a day or two.
  • Don’t skip the lemon juice. It doesn’t make the crisp lemony. It just brightens the peach flavor. Without it, the filling can taste flat.
  • Keep the butter cold. Non-negotiable. Cold butter makes a shaggy, sandy topping. Warm butter makes a paste. If your kitchen is hot, pop the butter cubes in the freezer for 10 minutes before you start.
  • Use old-fashioned oats. There’s a reason the recipe mentions them first. Old-fashioned rolled oats stay intact and crisp. Quick oats turn mushy.
  • Let it rest. Give the crisp at least 10 minutes after baking. The filling thickens as it settles, so you get neat portions instead of a puddle.

And a few mistakes to avoid, because I’ve made them all:

Using under-ripe peaches. They won’t soften enough, and your crisp will be crunchy in a bad way.
✅ Let them ripen on the counter for a day or two first.

Overmixing the topping. It turns into dough and bakes up dense.
✅ Stop when you see coarse crumbs. It’s supposed to look shaggy.

Not resting the crisp before serving. Trust me, I’ve burned my tongue more than once.
✅ Ten minutes. Set a timer. It’s worth it.

If your topping starts browning too fast in the oven, it’s not your fault. Just tent the dish loosely with foil for the last 10 minutes. Every oven runs a little different, and this recipe is forgiving.

Peach Crisp Variations & Substitutions

This easy peach crisp recipe is flexible, and that’s one of the reasons I love it. Here are some ways to make it your own:

  • Gluten-free: Use a 1-to-1 gluten-free flour blend in both the filling and the topping, plus certified gluten-free oats. You genuinely won’t miss the regular flour.
  • Vegan: Swap the butter for melted coconut oil and serve with dairy-free ice cream or coconut whipped cream. The texture will be slightly different, softer and more crumbly, but still delicious.
  • Nut-free: Just skip the pecans and add extra oats instead. The topping will still get plenty crisp, and nobody will miss the nuts.
  • Other fruit: Nectarines work perfectly, no changes needed. You can also swap in pears or apples, or do a mix of peaches and summer berries like blueberries or blackberries. The lemon juice and cinnamon play well with all of them.
  • Dark brown sugar: Use it instead of light for more molasses depth. Both work fine, so go with what you have.
  • Individual crisps: Spoon the filling into ramekins or a muffin tin, top with streusel, and bake. They cook faster, so check at 30 minutes. These freeze really well too, a great option for meal prep.

And about the cobbler question: a cobbler uses a biscuit-style topping, while a crisp uses that buttery oat streusel. This recipe is firmly in the crisp camp, and that’s exactly where I think it shines.

How to Store & Reheat Peach Crisp

If you somehow have leftovers, here’s how to handle them. This easy peach crisp keeps beautifully.

Fridge: Cover the dish tightly and refrigerate for up to 5 days. The topping will soften a bit, but that’s normal and it still tastes great.

Reheating: Warm individual portions in the microwave for about 30 seconds. Or reheat the whole dish in a 350°F oven for about 15 minutes. The oven brings back some of the crunch, which is nice.

Freezer: You can freeze the baked crisp for up to 3 months. Wrap it tightly in plastic wrap and foil, then thaw overnight in the fridge and reheat at 350°F until warmed through.

peach crisp - final presentation

Serve it warm with vanilla ice cream melting over the top. That’s the classic move. Whipped cream works too, or a dollop of crème fraîche if you want to be fancy. Honestly, even cold out of the fridge with a spoon, it’s dangerous.

And if you’re planning ahead, you can assemble the whole unbaked crisp a day early, keep it covered in the fridge, and bake it the next day. Just add 5 to 10 minutes to the bake time since it starts cold. That makes this easy peach crisp perfect for holiday dinners or a stress-free cookout.

What’s the difference between peach crisp and peach cobbler?

A cobbler gets a biscuit-style topping spooned over the fruit in dollops. A crisp has a streusel topping made with butter, flour, brown sugar, and oats. If you’re after that crunchy, crackly topping, a crisp is your answer. This easy peach crisp delivers exactly that, every single time.

Can I use frozen peaches in peach crisp?

Yes. Thaw them first, drain off the excess liquid, and pat them dry before tossing with the other filling ingredients. This prevents a watery filling. You may need to add about 5 minutes to the bake time since the fruit starts colder, so keep an eye on those bubbling edges.

Can I use canned peaches in peach crisp?

You can, and it’s a great year-round option. Use about 2 (15-ounce) cans, drained very well. Canned peaches are softer and sweeter, so reduce the sugar in the filling slightly. Pat them dry, then follow the recipe as written. The topping will still bake up perfectly golden.

Can I make peach crisp without oats?

Yes. The oats add that classic crumble texture, but you can swap them for an equal amount of extra flour and a few more chopped pecans if you’re out of oats. The topping will be a bit more like a shortbread crumble, which is honestly delicious too. Nobody will complain.

Can you make this easy peach crisp ahead of time?

Absolutely. Assemble the unbaked crisp, cover it, and refrigerate for up to a day. If baking from cold, add 5 to 10 minutes to the oven time. You can also bake it fully and reheat it later. Leftovers keep well in the fridge for up to 5 days, if they last that long.

Can I double this peach crisp recipe?

Definitely. Double everything and use a 9×13-inch baking dish. Plan for a slightly longer bake time, closer to 55 to 60 minutes. Watch the topping; if it browns too quickly, tent it loosely with foil. This easy peach crisp scales beautifully for a crowd.

Can I use other fruit instead of peaches?

This recipe is very flexible. Nectarines work beautifully with zero changes. You can also swap in pears, apples, or a mix of peaches and summer berries like blueberries or blackberries. The lemon juice and cinnamon play nicely with all of them, so feel free to experiment.
