Skillet Apple Crisp

Being from the North, I am an apple addict. The number of apples I have consumed in my life- oh my gosh. I grew up near Apple Orchards, apple picked often and made just about any type of apple dish you could think of.

However, as a lazy vegan, I do not have any desire to make a vegan crisp that will take me hours or make me hunt down weird ingredients.

I also want to add some pizazz to it, because why limit this crisp just to apples.

So, I decided to take traditional vegan apple crisp, add some lemons and blueberries to it, then bake it up in a cast-iron skillet. The results were phenomenal.

The sweet apple flavors harmonize with the fresh blueberries and zesty lemon. All topped with a maple brown sugar crisp.

So, let’s make it!

Why Make This Apple Crisp In a Cast Iron Skillet

Easy & Quick - this recipe is simple to make, taking 30 minutes to bake and approximately 15 minutes to make. There are minimum steps, which are mainly mixing ingredients.

Full of Flavor - Unlike normal apple or blueberry crisp, this crisp combines three delicious flavors - blueberry, apples, and lemon. The delicious blueberries burst with flavor and pairs well with the zesty lemon and warm apple taste.

Crowd Pleaser- Everyone loves a cast iron dish. Okay, maybe not everyone, but most people. I do not know if I ever heard someone say they did not enjoy their cast iron fajitas or cookie skillet.

Sturdy - A cast iron dish is so sturdy, making it an easy way to transport your crisp to picnics, parties, or holiday gatherings.

Why Make It A Mini Skillet Apple Crisp

How many times have you baked something and half of it ends up going bad before you are able to enjoy it?

This cast iron apple crisp is perfect for two people to enjoy, or just one very hungry person.

Skilled Apple Crisp

If you are planning to make this recipe for more than two people, you can easily double it.


To make this vegan cast iron recipe, you will need the following: 1 Gala Apple; fresh blueberries; lemon juice & zest; maple syrup; cornstarch; allspice; cinnamon; nutmeg; rolled oats; flour; melted vegan butter; walnuts; and brown sugar.

Ingredients for Topping
Substitutions and Alternatives

Sugar Free- If you want to make this apple crisp sugar free, sub liquid stevia for the maple syrup and regular stevia for the brown sugar.

Less Spices - If you only have cinnamon and not nutmeg and allspice, sub cinnamon for all three.

Gluten Free - What about the flour? You may sub 1-1 gluten-free flour to make this a gluten-free blueberry crisp. I have not tried this.

Butter- If you need to sub vegan butter, use another high-fat alternative, such as coconut oil.

If you swap for something that does not have a higher fat content, the crisp topping will not crisp up as well.

Nut Free- Walnuts are used in this recipe. If you want it to be nut free, use sunflower seeds or omit nuts entirely.

You will also need a cast iron. I used this cast iron from amazon.

Making The Crisp

This mini skillet apple crisp recipe is so simple to make. The most laborious part is peeling and removing the core.

If you want to cut down about 3-5 minutes from this recipe, buy pre-peeled apple slices. Then, you will just need to cut them into tiny bit size pieces.

Steps to Make Skillet Apple Crisp
Prepping the Apples

Once you are done peeling the apples you will then need to cut them into bite-size pieces. Think the size of a blueberry. I have placed an example above for your reference.

It is okay if they are not all the same uniform size. If you cut them too large, however, you will have issues with bitting them.

One thing to note is not to cut them too thin. This will result in them cooking quickly and breaking down a little too much.

Making the Fruit Filling

Next, place the cut apples into a medium-size mixing bowl. Gently mix in the blueberries, lemon juice, and zest, maple syrup, corn starch and spices.

The mix will be well coated.

Spread a layer of the apple blueberry filling into your cast iron skillet. I used a 5 inch cast iron skillet because this is a mini skillet apple crisp.

Note, the size of your cast iron will affect the baking time. If you have a normal size cast iron for this recipe, you may need to cook it for longer.

Making the Brown Sugar Oat Topping

Next, you will make your topping, which is so simple. In a small bowl, you will mix all your topping ingredients in a medium-sized bowl.

Simply sprinkle the topping on top of the filling.

Pop in the oven and bake!

How To Store This Vegan Apple Crisp

Like most things, this crisp is best served immediately.

If for any reason you want to pre-make it for an event, I would suggest making the raw topping and the raw filling and keeping them in containers in the fridge until you are ready to bake the skillet apple crisp.

If you do this, be sure to remove the topping from the fridge for 30 minutes before using it to allow the butter to become room temperature.

If you do need to store the made skillet crisp, simply place it in an air-tight container in the fridge for up to 3 days.

When reheating the crisp, place it back into the cast iron and heat for 15 minutes at 350 F degrees.

Expert Tips

What are the best apples to use for Apple Crisp ?

I used Gala Apples to make this recipe. Gala apples will turn soft from baking quickly and also break down nicely so they are easy and soft to eat. You may use another soft apple as well, such as fuji.

Well, you may be thinking, I love Granny Smith apples, why can't I use those?

Trust me, I love them too. Granny smiths can take a very, very long time to bake. That is not saying you cannot use a granny smith apple, but if you do, I suggest you pre-cook the apples to break them down more in the skillet beforehand.

Should I use Fresh or Frozen Blueberries?

I used fresh blueberries, and I have not tested this recipe with frozen blueberries.

If you do use frozen blueberries, I would recommend that you bring them to room temperature then remove any excess water. Too much water will cause this crisp to be soggy.


Can I make this mini skillet apple crisp GF?

Yes, you can swap out gluten-free flour at a 1-1 basis.

How can I adjust this recipe for a 12 inch cast iron skillet?

Simply times the recipe by 2. There is an option to do this on my recipe card below (see the 2x below the picture above the recipe).

If you have a 10 inch cast iron skillet, you can also double the recipe, but cook times may vary.

What specific apple should I use for this skillet apple crisp?

I suggest you use gala apples for this recipe, as they are soft and cook easier. You may also use another soft apple, such as fuji.
