Best Peach Crisp Recipe for Cast Iron Skillet

Here is what you’ll need to make this cast iron skillet peach crisp:

Peach Filling Ingredients

  • Fresh Peaches: 10 ripe peeled and sliced peaches that filled a 10″ cast iron skillet or baking dish.
  • Maple Syrup: A delicious unrefined sweetener.
  • Pure Vanilla Extract: adding vanilla complements the cinnamon, nutmeg, and maple syrup.
  • Nutmeg and Cinnamon: These warm spices bring out the flavor of the crisp oat topping and the peach fruit filling.
  • Flour: Instead of cornstarch, I use old-fashioned all-purpose flour to help thicken the peach filling. If you are gluten-free, you can substitute gluten-free all-purpose flour.

Crisp Oat Topping Ingredients

  • Butter: cold butter must be used to get the right texture for a crisp topping. 
  • Oats: I used old-fashioned organic oats.
  • Cinnamon: creates a delicious flavor in the oat topping.
  • Maple Syrup: this is a healthy option for making the crisp oat topping instead of brown sugar.

How to Make Peach Crisp in a Cast Iron Skillet

Here are step-by-step instructions for making the best peach crisp in a skillet: 

1. Preheat the Oven: Turn on your oven to 350°F (175°C) so it has time to heat up. Spread a thin layer of butter on the bottom and sides of your 10-inch cast iron skillet.

2. Make the Peach Filling: In a large bowl, combine the sliced peaches, maple syrup, flour, nutmeg, ground cinnamon, and vanilla. Toss gently to coat the peaches evenly and then pour into the cast iron skillet.

3. Create the Crisp Topping: In a separate bowl, combine the flour and cinnamon. Slice butter into thin slices and add to the flour mixture. Using a pastry cutter, your fingertips, or two forks, work the cold butter into the dry ingredients until a crumbly mixture forms. Add maple syrup and gently stir until a dough forms. Mix in oats and stir until thoroughly mixed into the dough.

4. Assemble: Sprinkle the crumbly topping evenly over the peaches in the skillet. The topping may clump together, so use your hands to gently break it up and spread it out in an even layer over the fruit.

5. Bake: Bake the crisp in the oven for 40-45 minutes, or until the topping is golden brown and the peaches are bubbling around the edges.

7. Serve: Let the freshly baked peach crisp rest for at least 15 minutes before serving to help the juice thicken.

Serving and Storing

  • Enjoy this peach crisp warm from the oven! Top it with vanilla ice cream or maple cinnamon whipped cream.
  • Leftovers? Let the crisp cool completely, then store it in an airtight container in the fridge for 4-5 days.
  • For the best texture, reheat the entire crisp in the oven at 350°F for 10-15 minutes, or until warm. You can also use the microwave, but the oven will keep the topping crispier.
