  • Cast Iron Skillet: I used a 12″ cast-iron skillet for this recipe, but a 10″ medium-sized skillet will also work. No cast iron skillet? That is okay; use a baking dish.
  • Medium Bowl: my favorite mixing bowls are the kind grandma would have used, and these stoneware bowls come in various sizes.
  • Vegetable Peeler: use a vegetable peeler to peel the apples. If you have an apple peeler, it would be the best way to peel, slice, and core in one simple motion.
  • Pastry Cutter: an essential kitchen tool, a pastry cutter is used for cutting butter into the flour mixture.

Apple Crisp Ingredients

There are two parts to making a homemade crisp, the apple layer and the oat topping. I use the same crisp oat topping recipe that I use for my peach crisp recipe.

Apple Crisp Filling

  • Honeycrisp Apples: for this recipe, you will need enough apples to fill the cast iron skillet 3/4 full, peeled, and cut into small pieces. Please see the notes below of what kind of apples to use.
  • Flour: all-purpose flour is used to thicken the filling.
  • Maple Syrup: instead of using brown sugar to sweeten the filling, this recipe uses maple syrup to add sweetness and an irresistible flavor! Maple syrup is used in both the apple mixture and crisp oat topping.
  • Spices: delicious fall spices of cinnamon and allspice are added to the apple layer, while just cinnamon is added to the oat topping.
  • Vanilla: complement all the warm flavors of this skillet apple with a little bit of vanilla.

Apple Crisp Topping

  • Butter: to make the oat mixture, you will need to use very cold butter cut into thin slices.
  • Flour: all-purpose flour is used to make the oat crisp.
  • Oats: old-fashioned oats form the base of the topping. Avoid using quick oats because they will break down while baking. 
  • Cinnamon: add this warm spice to the oat topping for a more delicious flavor.
  • Maple Syrup: instead of sugar, I use maple syrup as a healthier option for the crisp topping.

How to Make Cast Iron Skillet Apple Crisp

I love that this crisp is much simpler to make than a homemade apple pie. My skillet apple crisp is packed with fresh, juicy Honeycrisp apples that are perfectly sweetened with warm spices and maple syrup, then baked until tender.

The hardest part about this recipe is peeling and slicing the apples. If you want to make the process faster, peel, core, and slice the apples all at once, here’s an apple peeler and corer in one!

Here is how to make the best apple crisp recipe!

Step 1: Preheat Oven

Preheat the oven to 350 degrees F. Lightly butter a 12-inch well-seasoned cast iron skillet. Set aside.

Step 2: Peel, Slice, and Dice Apples

Use a vegetable peeler or a small knife to peel apples. While some apple crisp recipes use apple slices, I prefer to cut the apples into thinly sliced chunks as they are easier to eat with a fork or spoon.

Cut the apple chunks into a uniform 1/2-inch thickness to ensure even cooking and faster softening. Place sliced apple chunks into the bottom of the cast iron skillet and fill the skillet until it is 3/4 full.

Step 3: Add Maple Syrup Mixture

Add maple syrup and flour to the top of the apples in the skillet. Add cinnamon, allspice, and vanilla and stir well. Toss the apples in the sauce mixture until fully coated.

Step 4: Bake the Apple Filling

Place the skillet with the apple filling into the oven and bake for 20 minutes.

Step 5: Make the Oat Topping

While the apple filling is baking, prepare the oat topping. In a medium mixing bowl, stir together the flour and cinnamon.

Add the cold slices of butter to the dry ingredients, and using a pastry cutter, cut the butter into the flour mixture until the mixture becomes super crumbly.

Stir the oats into the butter mixture. Then mix in the maple syrup. Stir until the ingredients are incorporated. The final texture of the oat topping will be a little sticky and resemble cookie dough.

Step 6: Add Crisp Oat Topping

Once the apples have been baked for 20 minutes, remove them from the oven, and stir to re-coat them in the hot maple syrup mixture.

Sprinkle the crisp oat topping mixture evenly over the top of the apple filling.

Step 7: Bake

Return the cast iron skillet to the oven and bake for 30 to 40 more minutes until the filling bubbles around the edges and the top is nice and golden brown. Baking time may vary by oven.

Step 8: Cool and Serve

Remove the crisp from the oven, allow the baked crisp to rest at room temperature, and cool for at least 15-20 minutes before serving. Allowing the crisp to cool gives the sauce a chance to thicken as it cools.

Serve warm with a scoop of vanilla ice cream or whipped cream to make it extra delicious!

How to Store Leftovers

To store leftover apple crisp, cool completely, then transfer to an airtight container or dish. Refrigerate for up to 5 days.

To reheat, set the oven to 350 degrees. Remove the cover from the dessert to allow for the best reheating. Bake in an oven-safe dish or cast iron skillet for about 20 minutes to reheat apple crisp, so the crisp does not burn.

  1. My oven went out so I thought I’d make this and put it on the traeger. It was amazing even after I ran out of pellets half way through. It was 9:30 at night by the time it was done and I had to have it. I’m not even an experienced cook. I recommend
