This Cast Iron Skillet Apple Crisp caramelizes the apples on the stovetop before they ever hit the oven, which gives the filling a depth of flavor a regular baked crisp never gets close to. It's still a one-pan dessert topped with buttery brown sugar oats that comes together in about 45 minutes, but it tastes like you worked harder than you did.

Note from Erin

The first time I made a skillet apple crisp with oats, I couldn’t believe the difference. Same ingredients, same topping as the version I’d always baked in a dish.

But starting the apples on the stovetop with the butter and brown sugar gives them this caramelly flavor you just don't get when you dump everything in a baking dish and bake it. It's hard to explain exactly. It's just good.

The recipe card at the bottom of this post includes the complete list of ingredients, measurements, and instructions.

For the perfect apple crisp, use a combination of apples. One variety on its own tends to taste flat compared to a sweet-and-tart mix.

Honeycrisp and Granny Smith are my go-to pairings, but any of these work well:

Honeycrisp: Crisp, juicy, and sweet. One of my favorites for any baked apple dessert.
Gravenstein: Tart with firm flesh that holds its shape through baking.
Granny Smith: Tart and crisp. Best paired with something sweeter.
Jazz: Mildly sweet with a slight spiced note.
Jonagold: Honey-like flavor that leans sweet without being one-note.
Pink Lady: Balanced sweet and tart in a single apple, so you can use it solo in a pinch.
York: Mellow flavor and holds its shape in baking.

Apples to avoid: Macintosh and Golden Delicious break down too much during baking, turning your filling mushy. Save those for applesauce.

Step-by-Step Tips to Make the Best Apple Crisp

Make the Crisp Topping

Use cold butter straight from the fridge. Working the mixture until you have pea-sized pieces of cold butter mixed in will give clusters of crispy topping.

Slice the Apples

Leaving the peel or removing it is a personal preference. The peels soften during baking, but they don't fully break down, and I find the texture chewy in a way I don't love, so I always peel.
Tip: Place the apples in lemon-lime soda or in a solution of 1 tablespoon lemon juice and 1 cup water to keep them from turning brown as you work.

Caramelize the Filling

Once the apples are coated and on the stovetop, leave them mostly alone. Heavy stirring breaks down the apple slices before they have a chance to hold their shape through baking.

Top and Bake

The topping may brown before the apples are fully cooked, so don't go by color alone. Slide a table knife into an apple slice towards the center of the skillet. It should slide in with little resistance.
Let the crisp rest for at least 5 minutes before serving. This helps the filling set up and makes clean slicing much easier.

What to Serve with Apple Crisp

Honestly, most of the time when I make homemade oat apple crisp I just serve it with a simple scoop of vanilla ice cream and a drizzle of caramel sauce. The cold ice cream against the warm, jammy apples is the whole reason apple crisp exists.

If you want to make it feel a little more put-together for a dinner party, I'd swap the ice cream for a dollop of cinnamon whipped cream or caramel whipped cream. Both come together in about five minutes and taste extra delicious.

And if you’re filling out a whole holiday dessert table, I've got plenty more delicious desserts to try.

Recipe Variations

Turn it into a pie: This same filling works in my apple pie with graham cracker crust if you want a sliceable version instead.

Add nuts: Stir 1 cup of chopped walnuts or pecans into the topping before sprinkling over the apples. The toasted nuts in the oven add a great contrasting texture.

Mixed fruit crisp: Swap two of the cups of apples for fresh or frozen blueberries. The blueberries break down into the filling, turning it a deep purple-red color that's stunning on a plate.
