Easy Apple Crisp Recipe (Old-Fashioned, Made with Oats)

by Profile photo of BityBity

If there’s one dessert that makes my whole kitchen smell like fall, it’s this apple crisp recipe. Soft cinnamon apples on the bottom, a buttery oat crumble on top, and those slightly caramelized bits around the edge of the pan that I will happily fight someone for.

I’ve been making some version of apple crisp since I was barely tall enough to see over the counter, and honestly, it’s still the dessert I reach for when I want something cozy without much effort. There’s no crust to roll, no dough to chill, and no fussy technique to worry about. You slice a few apples, stir a crumble together in one bowl, and then let the oven do the real work. About forty-five minutes later you’ve got bubbling fruit and a golden, crackly top. Serve it warm with a scoop of vanilla ice cream so it starts melting into all the little gaps, and I promise everyone will circle back for seconds before you’ve even sat down.

Why You’ll Love This Easy Apple Crisp

Some desserts are a whole production. This one, though, is basically a weeknight. Here’s why this easy apple crisp recipe has earned a permanent spot in my rotation.

  • It’s genuinely simple. One bowl for the apples, one for the topping, and no mixer anywhere in sight. If you can stir, you’re most of the way there.
  • You probably have everything already. Apples, sugar, oats, flour, butter, and cinnamon. Nothing fancy, and nothing you’ll need to hunt down at three different stores.
  • That topping, though. Because the oats bake into buttery golden clusters, you get real crunch on top of the soft, jammy apples underneath.
  • It bends to whatever you need. It naturally works with oats or without them, and it’s easy to make gluten free, which I’ll walk you through a little further down.

Ingredient Notes

A good apple crisp really does come down to a few small choices, so here’s what I’d keep in mind before you start.

  • Apples. You’ll want about six medium apples, or roughly two pounds. Firm, slightly tart apples are ideal because they hold their shape instead of collapsing into mush. I usually reach for Granny Smith, Honeycrisp, or Braeburn, and a mix of tart and sweet is even better.
  • Rolled oats. Old-fashioned rolled oats give you that classic hearty topping. Quick oats will work in a pinch, but they turn out finer and a little less craggy.
  • Brown sugar. Packed brown sugar in the topping adds a soft caramel note and helps everything crisp up, while plain granulated sugar goes in with the apples.
  • Butter. Melted unsalted butter is the glue here. It’s what turns loose oats and flour into those craveable crumbly clusters.
  • Cinnamon. Non-negotiable in my book. A full teaspoon warms up the apples, and a pinch of nutmeg is lovely too if you’re in the mood.

The Best Apples for Apple Crisp

People ask me about this one more than anything else, so it’s worth its own little rundown. The best apples for apple crisp are firm and a bit tart, because they soften as they bake without dissolving into applesauce, and their tartness balances all that sugar on top. Honestly, the apple you choose makes a bigger difference than any other single decision here.

These are the ones I reach for again and again:

  • Granny Smith is my top pick. It’s tart, firm, and holds its shape beautifully.
  • Honeycrisp brings natural sweetness and a great texture, so it’s lovely on its own or in a mix.
  • Braeburn and Jonagold both stay firm and land in that nice sweet and tart middle ground.
  • Fuji or Gala lean sweeter, so reach for them when you want a mellower, less tangy crisp.

My honest advice is to use a mix. A couple of Granny Smith for structure and tang, plus a sweeter variety like Honeycrisp, gives you the most interesting flavor. As for what to skip, I’d steer clear of Red Delicious and McIntosh, since they tend to turn soft and watery once they bake.

How To Make This Apple Crisp Recipe

The whole thing really comes down to three easy moves: toss the apples, mix the topping, and bake. Here’s how it goes, and you’ll find the full measurements in the recipe card at the bottom of this post.

1. Prep the apples. First, preheat your oven to 350 degrees F (175 degrees C) and lightly grease a nine-inch baking dish. Then peel and slice your apples, and toss them in a big bowl with the granulated sugar and cinnamon until every slice is coated.

2. Mix the oat crumble. Next, in a separate bowl, stir together the oats, flour, and brown sugar. Pour in the melted butter and mix until the whole thing looks like clumpy wet sand. Those clumps are exactly what you want, because they are what bake into the crispy bits later.

3. Assemble and bake. After that, spread the apples into an even layer and scatter the topping over them so the fruit is fully covered. Bake for 40 to 45 minutes, until the edges are bubbling and the topping is a deep golden brown.

Finally, let it cool for about ten minutes before you dig in. I know that’s the hardest part, but the filling thickens as it rests, so you’ll get cleaner scoops and save yourself a molten-apple moment.

How To Get a Crispy Apple Crisp Topping

The topping is really the whole point, right? If yours has ever come out soft or a little pale, a few small things usually turn it around.

  • Use old-fashioned rolled oats, not quick oats. Rolled oats hold their shape and give you that craggy crunch, while quick oats tend to bake up soft.
  • Don’t overmix. Stir the melted butter in just until you get clumps. Those clumps bake into crisp little clusters, so if you work it into a smooth paste, you’ll lose the texture.
  • Give it some room. Scatter the topping in an even layer instead of packing it down, because a bit of air is what keeps it crisp.
  • Bake until it’s truly golden. Pale topping means soft topping. If the apples are done but the top still needs color, slide it under the broiler for a minute or two and keep a close eye on it.
  • Let it cool before covering. Trapping steam under a lid is the quickest way to soften a crisp topping, so always let leftovers cool fully first.

Tips for the Best Apple Crisp

A few more things I’ve picked up after making this more times than I can count:

  • Slice the apples evenly. Similar-sized pieces cook at the same rate, so you won’t end up with some mushy and some crunchy.
  • Taste your apples first. If they’re very sweet, ease back on the sugar in the filling. If they’re mouth-puckering tart, add a touch more.
  • Use the right dish. A nine-inch square pan or a similar baking dish gives you a good ratio of fruit to topping. Go too big and it bakes thin and dries out.
  • Slide a tray underneath. The filling loves to bubble over, so set a baking sheet under the dish to save yourself an oven cleanup.
  • Always rest it. I know I keep repeating this, but ten minutes out of the oven lets the juices thicken so every scoop holds together.

Storage Options

If you somehow end up with leftovers, here’s how to keep them.

  • Refrigerator. Cover and store in the fridge for up to four days.
  • Reheat. Warm it in a 325 degree F oven so the topping crisps back up, or microwave a single portion for 30 to 45 seconds when you’re impatient (no judgment here).
  • Freezer. Freeze the baked and cooled crisp for up to two months, then thaw it overnight in the fridge before reheating.
  • Make ahead. You can also assemble it unbaked, cover it well, and keep it in the fridge for up to 24 hours before baking.

Variations and Substitutions

This apple crisp recipe is an easy one to make your own, so here are a few ways I like to switch it up.

  • Gluten free. Swap the flour for a one-to-one gluten-free blend and use certified gluten-free oats. It comes out just as crisp. For more sweet ideas, take a look at our gluten-free dessert recipes.
  • Without oats. Skip the oats, bump up the flour a little, and stir in a handful of chopped pecans for a more classic streusel.
  • Warmer spice. A pinch of nutmeg, a little ginger, or a splash of vanilla in the apples adds real depth.
  • Berry twist. Toss a cup of cranberries or blackberries in with the apples for a tart, jammy contrast.
  • Make it a party. If you love this, you’ll probably love our apple crisp pizza too.

What To Serve With Apple Crisp

Apple crisp plays well with almost anything sweet and creamy. A few of my favorites, since someone always asks:

  • A scoop of vanilla ice cream melting into the warm topping, which is the classic for a good reason
  • A generous drizzle of salted caramel sauce
  • Freshly whipped cream, or a pour of custard if you want to go properly British about it
  • A hot cup of coffee or spiced cider on the side

And if you’re building out a whole fall dessert table, our sweet potato pie makes a lovely partner. For more cozy desserts to bake next, our matcha chocolate chip cookies and a batch of caramel pecan turtle fudge never last long around here.

Frequently Asked Questions

Ingredients, Swaps, and Make-Ahead

What are the best apples for apple crisp?

Firm, slightly tart apples that hold their shape when baked are ideal. Granny Smith is my go-to, but Honeycrisp, Braeburn, and Fuji all work beautifully. For the best flavor, use a mix of tart and sweet apples so the filling doesn’t turn one-note or mushy.

What’s the difference between apple crisp and apple crumble?

They’re very close cousins. An apple crisp has oats in the topping, which gives it that signature crunchy, craggy texture. An apple crumble traditionally skips the oats for a finer, more streusel-like topping made from just flour, sugar, and butter. Thanks to the rolled oats, this recipe is a true crisp.

Can I make apple crisp gluten free?

Yes, and it’s easy. Just replace the all-purpose flour with a one-to-one gluten-free baking blend, and make sure your oats are certified gluten free, since oats are often cross-contaminated. The result is every bit as crisp and buttery.

Can I make this apple crisp recipe ahead of time?

Absolutely. You can assemble the whole thing unbaked, cover it, and refrigerate for up to 24 hours before baking. Or bake it fully, then reheat it in a 325 degree F oven so the topping crisps back up. It also freezes well for up to two months.

Baking Tips and Troubleshooting

Why did my apple crisp turn out soggy?

Usually it comes down to the apples. Softer varieties break down and release too much liquid, so stick with firm ones. Don’t skip the flour and sugar that thicken the juices either, and let the crisp rest for ten minutes after baking so the filling has time to set.

Do you have to peel the apples for apple crisp?

I like to peel them, since the skins can turn a little chewy once baked and the filling feels smoother without them. That said, it’s not the end of the world if you leave them on, especially with thin-skinned apples. It really comes down to how you like the texture.

Can I use quick oats instead of old-fashioned oats?

You can, but the topping won’t be quite as crisp. Old-fashioned rolled oats hold their shape and give you those craggy clusters, while quick oats break down and bake up softer. If quick oats are all you have, the crisp will still taste great, just a little less crunchy.

What size dish should I use?

A nine-inch square baking dish is my go-to for this amount, and an eight-inch works too if you want a slightly thicker crisp. If you double the recipe, step up to a nine-by-thirteen. Just avoid going too large, or the crisp bakes thin and can dry out.
