A good apple crisp needs three things: firm apples that keep their shape, a topping with enough cold butter to turn crunchy, and a hot oven that bubbles the fruit before the crumble burns. Get those right and the rest is forgiving. This easy apple crisp recipe uses about 2½ pounds of apples in an 8-inch square dish and bakes at 350°F for 45 to 55 minutes.
Below you will find which apples hold up, the topping ratio worth memorising, a full ingredient list, numbered steps, and how to make it ahead and store the leftovers safely. It is the kind of dessert you can put together while the oven preheats.
Key takeaways
- Use firm baking apples such as Granny Smith, Honeycrisp, Braeburn or Pink Lady, ideally a mix of tart and sweet.
- Topping ratio: roughly equal volumes of flour and oats, a little less brown sugar, and cold butter cut in until it clumps.
- Bake until the fruit bubbles thickly at the edges, not just until the top browns.
- Baked fruit crisps can sit covered on the counter for 1 to 2 days, but they keep longer in the fridge.
- Make the topping ahead and freeze it, then bake straight from cold for a near-instant dessert.

Pick apples that hold their shape
The single biggest difference between a crisp with distinct, tender slices and one that turns to applesauce is the variety. Soft, very juicy apples collapse in the heat. Firm ones soften but stay in pieces, which gives you texture against the crunchy lid.
The University of Illinois Extension apple guide lists Braeburn, Cameo, Cortland, Golden Delicious, Granny Smith, Gravenstein, Honeycrisp, Jazz, Jonagold and Pink Lady as suitable for pies, while McIntosh appears as a sauce apple rather than a pie apple. That is a useful shopping list for a crisp too, since the filling behaves much like pie filling without the crust.
Mix tart and sweet
One variety works, but two is better. A tart apple brings acidity and structure, a sweeter one brings aroma and body. A mix also covers you if one bag turns out softer than expected.
- All-rounder mix: half Granny Smith, half Honeycrisp.
- Sweeter mix: Pink Lady with Golden Delicious, plus an extra squeeze of lemon.
- Softer, saucier crisp: add one McIntosh to a firm base if you like some of the filling to melt into the juices.
Slice evenly
Cut apples into slices about ¼ inch thick, or into ½-inch chunks. Even pieces cook at the same rate. Peeling is optional; skins add colour and a little chew, and they save you ten minutes.
The topping ratio worth memorising
Most crisp toppings are built on the same frame: flour for structure, oats for crunch, brown sugar for caramel, butter to bind it all, and a pinch of salt so it does not taste flat. Once you know the ratio, you can scale it to any dish without a recipe.
| Topping part | 8-inch square dish | 9×13-inch dish | What it does |
|---|---|---|---|
| All-purpose flour | ¾ cup (about 95 g) | 1½ cups | Binds the crumble into clusters |
| Old-fashioned rolled oats | ¾ cup (about 70 g) | 1½ cups | Adds crunch and a toasty flavour |
| Packed brown sugar | ⅔ cup (about 140 g) | 1⅓ cups | Caramelises and browns |
| Cold unsalted butter | ½ cup / 1 stick (113 g) | 1 cup / 2 sticks | Creates crisp, craggy pieces |
| Cinnamon | ½ tsp | 1 tsp | Warm spice in the lid |
| Fine salt | ¼ tsp | ½ tsp | Balances the sugar |
The quick version: equal parts flour and oats, a bit less brown sugar, and about two-thirds as much butter as flour by volume. If you want a thicker, more generous lid, scale the whole topping up by half rather than just adding more butter.
Cold butter and a hot oven do more for a crisp topping than any secret ingredient.
Easy apple crisp: ingredients and steps
This makes one 8-inch square crisp, enough for six generous servings. Double everything for a 9×13-inch dish and add about 10 minutes to the bake.
Filling
- 6 medium firm apples (about 2½ lb / 1.1 kg), peeled or not, sliced ¼ inch thick
- ¼ cup granulated sugar (use 2 tbsp if your apples are sweet)
- 1 tbsp lemon juice
- 1 tbsp all-purpose flour or 2 tsp cornstarch
- 1 tsp ground cinnamon
- ¼ tsp ground nutmeg or allspice
- Pinch of salt
Topping
- ¾ cup all-purpose flour
- ¾ cup old-fashioned rolled oats (not instant)
- ⅔ cup packed light or dark brown sugar
- ½ tsp ground cinnamon
- ¼ tsp fine salt
- ½ cup (1 stick) cold unsalted butter, cut into small cubes
Method
- Heat the oven to 350°F (175°C) with a rack in the middle. Butter an 8-inch square baking dish or a 2-quart casserole.
- Toss the sliced apples with the sugar, lemon juice, flour or cornstarch, cinnamon, nutmeg and salt in a large bowl. Tip into the dish and level the top.
- In a second bowl, stir together the flour, oats, brown sugar, cinnamon and salt for the topping.
- Add the cold butter. Rub it in with your fingertips, or cut it in with a pastry blender or two forks, until no dry flour remains and the mixture forms pea-sized to marble-sized clumps.
- Scatter the topping evenly over the apples. Do not press it down; loose clumps bake crisper.
- Set the dish on a rimmed baking sheet to catch drips and bake for 45 to 55 minutes, until the topping is deep golden and the juices bubble thickly around the edges.
- If the top browns before the fruit is bubbling, lay a sheet of foil loosely over it for the last 10 to 15 minutes.
- Cool for at least 20 minutes so the juices thicken, then serve warm with vanilla ice cream, whipped cream or plain yogurt.

Make ahead, store and reheat
Apple crisp is a generous make-ahead dessert, and the topping is the part to prep. Rub the butter into the dry ingredients, then bag it and chill or freeze it. It goes straight from the freezer onto the fruit, no thawing needed, and frozen clumps often bake up crunchier than fresh.
Slice and mix the apples on the day you bake. Cut apples brown and weep juice as they sit, which softens the topping once it goes on.
How long leftovers keep
An extension expert answering on Ask Extension says baked fruit pies or crisps are safe covered on the counter for 1 to 2 days, as long as they contain no meringue, cream or dairy filling, and that they keep much longer in the refrigerator. For fruit pies made with sugar, Iowa State University’s AnswerLine gives up to two days at room temperature, then about two more days loosely wrapped in the fridge.
- Counter: cover and eat within 1 to 2 days.
- Fridge: move it in after that; a few more days is fine.
- Freezer: Iowa State suggests freezing a baked fruit pie uncovered until solid, then wrapping it, for up to four months. The same approach works for a crisp baked in a freezer-safe dish.
Bring back the crunch
The microwave warms crisp but softens the lid. For a crunchy top, reheat portions in a 350°F oven or toaster oven for 10 to 15 minutes. A whole frozen crisp can thaw on the counter for about an hour before going back in the oven until warm through.
Fixes and easy variations
When it goes wrong
- Soupy filling: the apples were juicy or it was served too hot. Add another teaspoon of cornstarch next time and let it rest a full 20 to 30 minutes.
- Pale, soft topping: the butter was too warm or the topping was packed down. Keep butter cold and scatter loosely.
- Burnt top, firm apples: slices were too thick. Cut thinner and tent with foil earlier.
- Too sweet: cut the filling sugar to 2 tbsp and add more lemon.
Swaps that work
- Replace a quarter of the apples with pears or a cup of cranberries.
- Add ½ cup chopped pecans or walnuts to the topping.
- Use maple syrup instead of the granulated sugar in the filling.
- Swap the flour in the topping for almond flour or a certified gluten-free blend, and use certified gluten-free oats if that matters to you.

Apple crisp FAQ
Can I use quick oats instead of rolled oats?
You can, but the topping will be finer and less crunchy. Old-fashioned rolled oats give bigger, craggier clusters. Avoid steel-cut oats, which stay hard.
Do I need to peel the apples?
No. Peeled apples give a smoother, softer filling, while skins add colour and a bit of chew. Both work; it is purely preference.
What is the difference between a crisp and a crumble?
In everyday use the terms overlap. Many cooks use crisp for a topping with oats or nuts and crumble for a topping made from flour, sugar and butter alone.
Can I assemble it the night before?
It is better to prep the topping ahead and cut the apples on the day. Assembled crisps get soggy overnight as the fruit releases juice into the crumble.
Bake one this week
Buy two varieties of firm apples, mix a double batch of topping, and freeze half. Next time you want dessert, you only need to slice fruit and scatter. For more ideas once the dish is empty, see our fall baking recipes.
