Peach Crisp with Frozen Peaches

This peach crisp with frozen peaches recipe turns a bag from the freezer into a warm, bubbling dessert with a buttery oat topping. It skips the peeling and pitting that fresh peaches demand, so you can have it in the oven in about fifteen minutes.

The filling stays juicy and lightly spiced, and the topping bakes up golden and crisp, which is exactly what separates a true crisp from a cobbler.

Frozen peaches work so well here because they are picked and frozen at peak ripeness, which means you get consistent sweetness no matter the season. Once thawed and drained, they behave almost exactly like fresh peaches in the oven.

That makes this a reliable dessert for a random Tuesday in January just as much as for a summer cookout.

This recipe sticks close to the traditional version of peach crisp, with an oat and brown sugar topping over a lightly spiced fruit filling. It is the version most home cooks expect when they think of peach crisp, and it holds up well served plain or topped with a scoop of ice cream.

Why You’ll Love This Peach Crisp with Frozen Peaches

This is the kind of dessert you can pull together on a weeknight without any special planning. The peaches do the heavy lifting on flavor, and the topping needs only a handful of pantry staples.

It also happens to be one of the most forgiving desserts you can make. A little extra fruit or a slightly thicker topping will not throw off the final result.

Here is what makes it worth adding to your regular rotation:

• Uses frozen peaches year round. No need to wait for peach season or track down perfectly ripe fruit at the store.
• Comes together fast. Fifteen minutes of prep gets it in the oven, and the rest is hands off baking time.
• Buttery, crunchy topping. The oat and brown sugar streusel gets deeply golden and stays crisp even after it cools.
• Naturally sweet filling. Peaches bring most of the sweetness on their own, so the added sugar stays modest.
• Easy to scale. Double it for a crowd or halve it for a smaller pan without changing the method.
• Freezer friendly leftovers. The baked crisp reheats beautifully, so it is just as good the next day.
• Simple ingredient list. Everything needed is likely already in your pantry and freezer.
• Kid approved. The soft fruit and sweet topping make this an easy sell at the dinner table.

I often compare notes between this recipe and my apple crisp when friends ask which fruit dessert to start with.

Ingredients

Gather everything below before you start so the filling and topping come together quickly. Measurements are given in both cups and grams for convenience.

For the Peach Filling:

• 6 cups (about 900g) frozen sliced peaches, thawed and drained
• ⅓ cup (67g) granulated sugar
• 1 tablespoon (8g) cornstarch
• 1 tablespoon (15ml) fresh lemon juice
• 1 teaspoon ground cinnamon
• ¼ teaspoon ground nutmeg
• Pinch of fine salt
• 1 teaspoon pure vanilla extract

For the Oat Crumble Topping:

• 1 cup (90g) old-fashioned rolled oats
• ¾ cup (94g) all-purpose flour
• ⅔ cup (145g) packed brown sugar
• ½ teaspoon ground cinnamon
• ¼ teaspoon fine salt
• ½ cup (113g) cold unsalted butter, cubed
• ½ cup (60g) chopped pecans

I always drain the peaches well after thawing them. Skipping that step is the number one reason a peach crisp turns out watery instead of set.

Kitchen Equipment Needed

None of this requires anything fancy, but a few tools make the process smoother and help the crisp bake evenly.

• 9×13 inch baking dish
• Glass mixing bowl set
• Medium mixing bowl
• Fine mesh colander or strainer
• Measuring cups and spoons
• Pastry cutter
• Citrus juicer
• Whisk
• Digital kitchen scale
• Wire cooling rack

I splurged on a decent glass mixing bowl set a couple of years ago, and it turned out to be one of those small kitchen upgrades that gets used constantly, not just for this crisp but for nearly everything I bake.

A pastry cutter genuinely speeds things up. I used to cut the butter into the topping with two forks, and it took forever compared to a proper cutter.

This pairs beautifully with my fruit tart if you want two desserts on the table for a gathering.

Recommended Products for This Recipe

These are products I reach for myself when I make this crisp, based on what has actually made the biggest difference in the kitchen over the years.

1. USA Pan 9×13 Nonstick Baking Dish

This dish heats evenly and releases the crisp cleanly, even with all the bubbling fruit juice around the edges. The nonstick coating means less scrubbing afterward, which matters a lot on a weeknight. It has held up well through years of regular use in my kitchen.

2. OXO Good Grips Pastry Cutter

This tool cuts cold butter into the oat topping in seconds instead of minutes. The thick wires stay sharp and do not bend the way cheaper versions do. It is a small purchase that pays off every time you bake a crumble or crisp.

Get it on Amazon

3. Nielsen-Massey Pure Vanilla Extract

The difference between real vanilla extract and imitation is noticeable in a simple dessert like this one, where the fruit and topping are the whole show. I switched to this brand years ago and never looked back. A little goes a long way, so a bottle lasts a while.

Get it on Amazon

4. Fresh Whole Pecans

Pre-chopped pecans can taste stale sitting on a store shelf, so I prefer buying whole pecans and chopping them myself right before baking. The flavor and crunch are noticeably better. They also work well in plenty of other baked goods once you have a bag on hand.

Get it on Amazon

5. Ceylon Ground Cinnamon

Regular grocery store cinnamon works fine, but true Ceylon cinnamon has a softer, slightly citrusy flavor that I noticed right away once I switched. It makes a real difference in a dessert where cinnamon is one of the main flavors carrying the whole filling. A small tin lasts a long time since you only need a teaspoon or two per batch.

I like offering this alongside my poached pear when I want a lighter fruit option on the dessert table too.

Step-by-Step Instructions: How to Make Peach Crisp with Frozen Peaches

Follow these simple steps and you will have a warm, golden peach crisp ready to serve in under an hour.

1. Thaw and Drain the Peaches

• Move the frozen peaches to a colander set over a bowl and let them thaw at room temperature for about an hour, or thaw them overnight in the refrigerator.
• Once thawed, press gently on the peaches with a spoon to release excess liquid.
• Discard most of the collected juice, or save a splash to stir into a smoothie later.
• Pat the peaches lightly with a paper towel if they still feel very wet.

2. Preheat the Oven and Prep the Pan

• Preheat your oven to 350°F (175°C).
• Lightly grease the 9×13 inch baking dish with butter or nonstick spray.
• Set the dish aside while you finish the filling.

3. Make the Peach Filling

• In a large mixing bowl, combine the drained peaches, granulated sugar, cornstarch, lemon juice, cinnamon, nutmeg, and salt.
• Add the vanilla extract and toss everything gently until the peaches are evenly coated.
• Let the mixture sit for five minutes so the cornstarch starts to draw out a bit more juice, which helps thicken the filling as it bakes.
• Pour the peach mixture into the prepared baking dish and spread it into an even layer.

4. Mix the Oat Crumble Topping

• In a medium mixing bowl, whisk together the oats, flour, brown sugar, cinnamon, and salt.
• Add the cold cubed butter to the dry ingredients.
• Use a pastry cutter, or your fingers, to work the butter into the mixture until it resembles coarse, pea-sized crumbs.
• Stir in the chopped pecans until they are evenly distributed through the topping.

5. Assemble the Crisp

• Sprinkle the oat topping evenly over the peach filling, covering the fruit as completely as you can.
• Avoid pressing the topping down, since a looser texture bakes up crispier.
• Check that no large gaps of exposed fruit remain, especially near the edges of the dish.

6. Bake Until Golden and Bubbling

• Place the dish in the preheated oven and bake for 35 to 40 minutes.
• Look for a deep golden topping and thick, bubbling juices around the edges as your cue that it is done.
• If the topping browns too quickly, loosely tent the dish with foil for the last ten minutes of baking.

7. Cool and Serve

• Remove the crisp from the oven and set it on a cooling rack.
• Let it rest for at least 15 minutes before serving so the filling has time to set slightly.
• Serve warm, on its own or with a scoop of vanilla ice cream.

The toasted pecans in the topping remind me a lot of the ones I use in my pecan pie, so if you love that flavor, you will love it here too.

Tips for The Best Peach Crisp with Frozen Peaches

A few small details make a real difference between an average crisp and one that turns out perfectly every time.

• Drain the peaches thoroughly. Extra liquid is the most common cause of a soggy, soupy crisp.
• Keep the butter cold. Cold butter creates distinct, crisp crumbs instead of melting into a paste.
• Do not skip the cornstarch. It thickens the fruit juices into a glossy sauce rather than a thin liquid.
• Use a light hand with the topping. Sprinkling it loosely instead of pressing it down helps it crisp up properly.
• Let it rest before slicing. Cutting in too soon means the filling will run instead of hold its shape.
• Watch the browning. Every oven runs a little differently, so start checking at the 30 minute mark.
• Add a splash of bourbon or almond extract. A small amount deepens the flavor of the fruit without overpowering it.
• Toast the pecans first. A quick five minute toast in a dry pan brings out more of their natural flavor before mixing them into the topping.

I learned the toasted pecan trick from a batch where I rushed and skipped it, and the difference in flavor the next time I toasted them first was obvious.

If you want a fruit dessert with a bit less sugar, my healthy apple pie is worth a try too.

What to Serve with Peach Crisp

Peach crisp is rich enough to stand on its own, but a few additions turn it into more of an occasion. Cold and creamy pairings work especially well against the warm, spiced fruit.

• Vanilla bean ice cream
• Softly whipped cream
• A drizzle of caramel sauce
• Chopped toasted pecans on top for extra crunch
• A cup of coffee or espresso alongside
• A scoop of vanilla Greek yogurt for a lighter option
• A glass of dessert wine, like a late harvest Riesling
• Fresh mint leaves for a bit of brightness

This pairs beautifully with my Peach Smoothie the next morning if you have leftover peaches on hand.

Variations of Peach Crisp with Frozen Peaches

Once you have the base recipe down, it is easy to change things up depending on what you have or what you are craving.

• Peach and berry crisp. Swap one cup of peaches for frozen blueberries or raspberries.
• Gluten-free version. Use a 1:1 gluten-free flour blend and certified gluten-free oats.
• Nut-free crisp. Leave out the pecans entirely, or replace them with extra oats for crunch.
• Ginger peach crisp. Add a half teaspoon of ground ginger to the filling for a warmer, spicier flavor.
• Bourbon peach crisp. Stir one tablespoon of bourbon into the peach filling before baking.
• Coconut crisp topping. Mix a quarter cup of shredded coconut into the oat topping.
• Individual crisps. Divide the filling and topping among small ramekins and reduce the bake time to about 20 minutes.
• Dairy-free version. Use a plant-based butter substitute in place of the cold butter.
• Streusel with almond flour. Replace half the all-purpose flour with almond flour for a nuttier, slightly denser topping.
• Maple peach crisp. Swap the brown sugar in the filling for pure maple syrup for a deeper, less refined sweetness.

Storage and Reheating

Leftover peach crisp holds up well, which makes it a great make-ahead dessert for busy weeks.

• Refrigerator: Store covered in the baking dish or an airtight container for up to 4 days.
• Freezer: Freeze baked and cooled crisp in an airtight container for up to 3 months.
• Reheating in the oven: Warm at 350°F (175°C) for about 15 minutes, uncovered, until heated through and the topping re-crisps.
• Reheating in the microwave: Heat individual portions in 30 second bursts, though the topping will soften slightly.
• Freezing unbaked: Assemble the crisp in a freezer-safe dish, wrap tightly, and freeze unbaked for up to 2 months. Bake straight from frozen, adding 15 to 20 extra minutes to the bake time.
• Avoid sealing while warm. Let the crisp cool completely before covering it, or condensation will make the topping soggy.
• Portion before freezing. Freezing the crisp in individual portions makes it easier to reheat only what you need instead of thawing the whole dish.

This pairs beautifully with my Fruit Cocktail Cake if you are planning a dessert table with make-ahead options.

FAQs About Peach Crisp with Frozen Peaches

1. Do I need to thaw frozen peaches before making crisp?

Yes, thawing and draining the peaches first is important. Baking them straight from frozen adds too much extra liquid and can leave the filling watery.

2. Can I use frozen peaches straight from frozen in a pinch?

You can, but expect a longer bake time and a thinner sauce. It is best to add an extra tablespoon of cornstarch and bake 10 to 15 minutes longer if you skip thawing.

3. Why is my peach crisp topping soggy instead of crisp?

This usually happens when the peaches were not drained well enough before assembling. It can also happen if the crisp is covered while still warm, which traps steam against the topping.

4. Can I make peach crisp ahead of time?

Yes, you can assemble it a day ahead and refrigerate it unbaked, then bake it fresh when you are ready to serve. You can also bake it fully in advance and reheat it before serving.

5. What is the difference between a peach crisp and a peach cobbler?

A crisp has a crumbly, streusel-style topping made with oats, while a cobbler is topped with biscuit-like dough or dropped batter. Both use a similar spiced peach filling underneath.
