Easy apple crisp is a baked dessert made with tender cinnamon-spiced apples topped with a buttery, golden oat streusel — no pie crust required, ready in about 50 minutes, and even better served warm with a scoop of vanilla ice cream. Unlike apple pie, there’s no rolling, chilling, or crimping involved. You simply toss the apples, mix the topping, layer them in a baking dish, and let the oven do all the work. It’s the easiest way to turn a bag of apples into something that tastes like it came from a bakery.
What Is Apple Crisp?
Apple crisp (also called apple crumble in the UK and Australia) is a classic American comfort dessert consisting of two components: a softened, warmly-spiced apple filling and a crunchy, crumbly topping made from oats, flour, butter, and brown sugar. The topping bakes up golden and crisp while the apples beneath become tender and jammy, releasing their juices and mingling with the cinnamon and sugar into a caramelized sauce.
The key difference between apple crisp and apple crumble is the oats: a crisp always contains rolled oats in the topping, which create that signature crunch and chewy texture. A crumble typically uses just flour, butter, and sugar. Both are delicious; the crisp just has more textural interest.
According to Serious Eats, the technique of adding oats to fruit toppings became popular in North America in the early 20th century as a way to stretch pantry ingredients, and it’s been a beloved shortcut dessert ever since.

Ingredients
Apple Filling
- 6 medium apples (about 2½ lbs) — peeled, cored, and sliced ¼ inch thick
- 3 tablespoons granulated sugar
- 2 tablespoons brown sugar
- 1 tablespoon fresh lemon juice
- 1 teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg
- ⅛ teaspoon ground ginger (optional, but recommended)
- 1 tablespoon cornstarch
Oat Crisp Topping
- 1 cup old-fashioned rolled oats (not instant)
- ¾ cup all-purpose flour
- ¾ cup packed brown sugar
- ½ teaspoon ground cinnamon
- ¼ teaspoon salt
- ½ cup (1 stick / 113g) cold unsalted butter, cut into small cubes
Key note on oats: Always use old-fashioned rolled oats, not quick oats or instant oats. Quick oats absorb moisture too fast and turn mushy; old-fashioned oats hold their structure and give the topping its signature chew and crunch.
Best Apples for Apple Crisp
Not all apples are created equal for baking. The best apples for crisp are firm varieties that hold their shape under heat rather than turning to mush.
- Granny Smith — The gold standard. Tart, firm, and holds shape perfectly. The tartness balances the sweet topping beautifully.
- Honeycrisp — Slightly sweet with excellent texture. Holds up well and adds natural sweetness so you can reduce the sugar slightly.
- Braeburn — Sweet-tart balance, very firm. Excellent for baking.
- Pink Lady (Cripps Pink) — Firm, aromatic, and slightly tart. One of the best all-around baking apples.
- Golden Delicious — Sweeter and softer; fine for crisp but can go mushy. Best mixed with a firmer variety.
Avoid Red Delicious apples for baking — they turn mealy and flavorless when cooked. A mix of Granny Smith and Honeycrisp is the best combination for apple crisp: the tartness and sweetness balance each other, and both hold their shape through a full 40 minutes in the oven.
Step-by-Step Instructions
Step 1: Prepare the Apple Filling
Preheat your oven to 350°F (177°C). Grease a 9×13 baking dish (or an equivalent-volume deep 9×9 square dish for a thicker crisp) with butter or non-stick spray.
Peel, core, and slice your apples to a consistent ¼-inch thickness. Uniform slices are important — they cook evenly, so you don’t end up with some mushy slices and some underdone slices. A mandoline makes this very fast, but a sharp knife and a little patience work just as well.
In a large bowl, toss the apple slices with the granulated sugar, brown sugar, lemon juice, cinnamon, nutmeg, ginger, and cornstarch. Make sure every slice is coated. The lemon juice serves two purposes: it adds brightness that balances the sweetness, and it prevents the apples from browning while you prepare the topping. The cornstarch thickens the apple juices as they cook, creating a glossy sauce at the bottom of the dish.
Spread the apple mixture evenly in your prepared baking dish. Set aside.
Step 2: Make the Oat Crisp Topping
In a separate bowl, combine the oats, flour, brown sugar, cinnamon, and salt. Whisk briefly to combine.
Add the cold butter cubes. Using your fingertips, work the butter into the dry ingredients by pinching and pressing until the mixture looks like coarse, clumpy wet sand with some larger pea-sized pieces of butter still visible. Those butter chunks are key — as they melt in the oven, they create pockets of steam that make the topping crisp and flaky rather than dense and heavy.
Critical tip: keep the butter cold. Cold butter creates steam as it bakes, which is what makes the topping crunchy. If the butter warms up too much before baking, the topping will spread into a greasy, flat layer rather than staying crumbly. If your kitchen is warm, mix the topping and refrigerate it for 10 minutes before using.
Step 3: Assemble and Bake
Sprinkle the oat topping evenly over the apple filling, covering it completely. Don’t press the topping down — leave it loose and crumbly so air can circulate and it crisps up properly.
Bake at 350°F for 35–45 minutes, until the topping is deep golden brown and the apple filling is bubbling up around the edges. The bubbling is your visual cue that the apple juices have come to temperature and the cornstarch has activated to thicken the sauce.
If the topping starts to brown too quickly before the apples are done, loosely tent the dish with aluminum foil for the last 10 minutes of baking.
Step 4: Rest and Serve
Let the apple crisp rest for at least 10 minutes after coming out of the oven. This resting time is important: it allows the thickened apple juices to set slightly so the crisp isn’t soupy when you serve it. The topping also continues to crisp up slightly as it cools.
Serve warm, directly from the baking dish, with a generous scoop of vanilla ice cream or a dollop of lightly whipped cream. The contrast of warm, caramelized apples and cold, melting ice cream is half the reason everyone loves this dessert.
How to Store Apple Crisp
Apple crisp stores well and is arguably better the next day, once the flavors have had time to meld.
- Room temperature: Cover loosely with foil and store at room temperature for up to 2 days. The topping will soften slightly overnight.
- Refrigerator: Cover tightly and refrigerate for up to 5 days. Reheat in a 350°F oven for 15–20 minutes to re-crisp the topping, or microwave individual portions for 60–90 seconds (topping won’t be as crisp).
- Freezer: Freeze baked apple crisp, covered tightly, for up to 3 months. Thaw overnight in the refrigerator and reheat in a 350°F oven for 20–25 minutes until warmed through and the topping is crisp again. You can also freeze the unbaked assembled crisp and bake directly from frozen, adding 15–20 extra minutes to the bake time.
Variations
Gluten-Free Apple Crisp
Substitute the all-purpose flour in the topping with certified gluten-free oat flour or a 1:1 gluten-free baking flour blend. Make sure your rolled oats are certified gluten-free (regular oats are often cross-contaminated with wheat). The rest of the recipe is naturally gluten-free.
Apple Pear Crisp
Replace 2–3 of the apples with ripe Bosc or Anjou pears for a more complex, floral flavor. Pears are softer than apples, so they cook faster — reduce the bake time slightly and check at 30 minutes.
Nutty Crisp Topping
Add ½ cup of chopped pecans or walnuts to the streusel topping before baking. The nuts toast in the oven and add a wonderful crunch and richness. Pecans are the most classic pairing with apple and cinnamon.
Caramel Apple Crisp
Drizzle ¼ cup of store-bought or homemade caramel sauce over the apple filling before adding the topping. The caramel deepens as it bakes into an intensely rich sauce. Serve with extra caramel drizzled on top. For homemade caramel, check out our caramel churros recipe — the same caramel sauce works beautifully here.
Spiced Chai Apple Crisp
Add ½ teaspoon of cardamom and a pinch of cloves to the apple filling along with the cinnamon. This creates a warm chai-spiced depth that pairs beautifully with the brown sugar topping. Excellent for fall entertaining.
Apple Crisp vs. Apple Cobbler vs. Apple Crumble
These three desserts are often confused. Here’s how they differ:
- Apple Crisp: Fruit filling + oat-based streusel topping (oats, flour, butter, sugar). The oats make the topping crispy and chewy.
- Apple Crumble: Fruit filling + crumble topping made from just flour, butter, and sugar — no oats. Denser, softer topping.
- Apple Cobbler: Fruit filling + drop biscuit or cake batter topping that bakes up soft and doughy, like a biscuit or sponge cake layer. Our peach cobbler uses this exact technique — the batter is poured over the fruit and rises up around it as it bakes.
If you love the cobbler approach with its soft biscuit topping, see our easy peach cobbler recipe. For a totally different baked apple dessert, try our classic pound cake served alongside warm apple slices, or our cinnamon rolls from scratch for another cinnamon-apple flavor combination.
Serving Ideas for Apple Crisp
- Classic: Warm from the oven with a scoop of vanilla ice cream
- Elegant: With a quenelle of crème fraîche and a drizzle of honey
- Brunch: Served at room temperature with Greek yogurt and granola on the side
- Dessert bar: Alongside other bar desserts like our lemon bars and fudgy brownies for a spread
- Make ahead: Bake the night before and reheat in the oven the next day — always impressive for dinner parties

Frequently Asked Questions
Why is my apple crisp topping not crispy?
Three common culprits: (1) the butter was too warm when mixed, causing a greasy topping rather than a flaky one — always use cold butter straight from the fridge; (2) the topping layer was too thin — use all the topping and don’t spread it too sparse; (3) the dish was covered during baking, trapping steam — bake uncovered for the full time, only tenting with foil if the top is browning before the apples are done.
Can I make apple crisp ahead of time?
Yes. You can assemble the crisp (filling + topping) up to 24 hours ahead, cover tightly, and refrigerate. Bake directly from the refrigerator, adding 5–10 extra minutes to the bake time. Alternatively, bake it fully, store covered in the fridge, and reheat in a 350°F oven for 15–20 minutes before serving.
How do I know when apple crisp is done?
Two visual cues: (1) the topping is deep golden brown all over, not just around the edges; (2) the apple juices are actively bubbling up around the edges and through any gaps in the topping. The bubbling tells you the cornstarch has activated and the sauce is thickening. Don’t pull it from the oven at the first sign of browning — you want it to bake until everything is caramelized and bubbling vigorously.
Can I make apple crisp without oats?
Yes — that’s called an apple crumble. Simply omit the oats and use 1 full cup of flour in the topping with the same butter and sugar ratios. The topping will be denser and softer, more like a shortbread crumble than a crunchy crisp. Both are delicious; it’s a matter of texture preference.
How many apples do I need for a 9×13 pan?
Plan on 6 medium apples (about 2½ lbs) for a 9×13 baking dish. For a smaller 8×8 or 9×9 dish, use 4 medium apples (about 1¾ lbs). The apples shrink considerably as they cook and release their juices, so it’s better to overfill the dish slightly at the start — the filling will settle down to the right level as it bakes.
