Ingredients You’ll Need
For the Cinnamon Apple Slices
- 3 medium apples
- 1 tablespoon melted unsalted butter or coconut oil
- 1 tablespoon pure maple syrup
- 1 teaspoon ground cinnamon
- ¼ teaspoon ground nutmeg, optional
- ½ teaspoon vanilla extract
- 1 teaspoon fresh lemon juice
- A small pinch of salt
Firm apples work best because they hold their shape during air frying. Honeycrisp, Fuji, Gala, and Pink Lady apples are good options. Granny Smith apples also work if you prefer a tart flavor.
For the Walnut Topping
- ⅓ cup chopped walnuts
- 1 teaspoon maple syrup, optional
- ⅛ teaspoon ground cinnamon
- 1 tablespoon raisins, optional
Walnuts add a rich, nutty flavor that pairs well with warm cinnamon apples. Chop them into small pieces so they are easy to sprinkle over the finished dish.
If you prefer a softer walnut texture, add them during the final few minutes of cooking. If you want a stronger toasted flavor, add them near the beginning and watch closely to prevent burning.
How to Make Air Fryer Roasted Cinnamon Apple Slices with Walnuts
Step 1: Wash and Slice the Apples
Rinse the apples under cool running water and pat them dry.
Remove the cores and seeds, then cut the apples into wedges or slices about ¼ to ½ inch thick.
Try to keep the slices close to the same thickness so they cook evenly. Thicker pieces stay firmer, while thinner slices soften more quickly.
You can leave the apple skins on for extra texture and color. Peel them first if you prefer a softer finish.
Step 2: Prepare the Cinnamon Mixture
Place the melted butter or coconut oil in a medium mixing bowl.
Add the maple syrup, ground cinnamon, nutmeg, vanilla extract, lemon juice, and a small pinch of salt.
Whisk until the mixture is evenly combined.
The lemon juice adds brightness and balances the sweetness, while the butter helps the cinnamon mixture coat the apple slices.
Step 3: Coat the Apple Slices
Add the sliced apples to the bowl.
Toss gently until each piece is coated with the cinnamon mixture.
Use a spatula or clean hands to spread the seasoning evenly without breaking the slices.
If the apples release a little juice, that is normal. Avoid adding extra liquid because too much moisture can make the apples soft instead of lightly caramelized.
Step 4: Preheat the Air Fryer
Preheat your air fryer to 350°F for about 3 minutes, if recommended by your appliance’s instructions.
Lightly grease the basket with an air-fryer-safe cooking spray if needed.
A preheated basket helps the apples begin cooking evenly as soon as they are added.
Step 5: Arrange the Apples in the Basket
Place the coated apple slices in the air fryer basket in a mostly single layer.
A little overlap is fine, but avoid piling the slices too high. Crowding can trap moisture and prevent the edges from browning.
If you have a small air fryer, cook the apples in batches for more even results.
Step 6: Air Fry Until Tender
Air fry the apples at 350°F for 8–12 minutes.
Shake the basket or turn the slices gently halfway through cooking.
Start checking after 8 minutes. The apples should be tender when pierced with a fork, with lightly golden edges and a warm cinnamon coating.
Cooking time depends on the apple variety, slice thickness, and air fryer model. Add another 2–3 minutes if you prefer softer apples.
Step 7: Add the Walnuts
While the apples cook, mix the chopped walnuts with the optional maple syrup and a pinch of cinnamon.
Sprinkle the walnut mixture over the apples during the final 2–3 minutes of cooking.
This timing helps the walnuts warm and toast lightly without burning.
If you prefer a stronger crunch, toast the walnuts separately in a dry skillet over medium-low heat for a few minutes, then sprinkle them over the cooked apples.
Step 8: Serve Warm
Carefully transfer the apples to a serving bowl.
Sprinkle with the optional raisins and any remaining walnuts.
Taste a slice and add a little extra cinnamon if desired.
Serve the apples warm on their own or with Greek yogurt, oatmeal, pancakes, or vanilla ice cream.
Tips for Perfect Cinnamon Apples
A few simple steps help the apples cook evenly and develop the best texture.
- Choose firm apples: Honeycrisp, Fuji, and Pink Lady hold their shape well.
- Cut evenly: Similar-sized slices cook at the same rate.
- Avoid excess liquid: Too much syrup or butter can make the apples soggy.
- Do not overcrowd the basket: Air circulation helps the edges brown.
- Add walnuts near the end: This reduces the risk of burnt nuts.
- Check early: Thin slices can soften faster than thick wedges.
- Adjust the sweetness: Taste the apples before adding extra maple syrup.
- Serve soon after cooking: The apples taste best while warm and the walnuts retain their crunch.
Easy Recipe Variations
Honey Cinnamon Apples
Replace the maple syrup with honey for a different sweet flavor. Use a small amount because honey can brown quickly.
Brown Sugar Cinnamon Apples
Replace the maple syrup with 1 tablespoon of light brown sugar. Toss well so the sugar coats the apple slices evenly.
Cinnamon Apple Slices with Pecans
Swap the walnuts for chopped pecans. Pecans offer a buttery flavor that works well with cinnamon and maple syrup.
Apple Pie Spice Version
Replace the ground cinnamon and nutmeg with about 1 teaspoon of apple pie spice. Check the blend first because some versions already contain nutmeg and ginger.
Vanilla Cinnamon Apples
Add an extra ¼ teaspoon of vanilla extract for a warmer dessert-style flavor.
Cinnamon Apples with Oats
Sprinkle a small amount of toasted rolled oats over the finished apples for added texture. Toast the oats separately because they may not cook evenly with the moist fruit.
What to Serve With Cinnamon Apple Slices
These air fryer apples work with both sweet breakfasts and simple desserts.
Try serving them with:
- Plain Greek yogurt
- Warm oatmeal
- Overnight oats
- Pancakes or waffles
- French toast
- Vanilla ice cream
- Cottage cheese
- Whole-grain toast with nut butter
- Chia pudding
For breakfast, spoon the warm apples over oatmeal and finish with chopped walnuts. For dessert, serve them with a small scoop of vanilla ice cream and a light drizzle of maple syrup.
Storage and Reheating
Let the apples cool before placing them in an airtight container.
Refrigerate leftovers for up to 3–4 days.
To reheat, place the apples in the air fryer at 325°F for about 2–4 minutes, checking to make sure they do not become too soft.
You can also warm them in the microwave in short intervals, although the walnuts may lose some of their crunch.
For the best texture, store extra walnuts separately and add them after reheating.
Meal Prep Tips
These apples can be prepared ahead for easy breakfasts and snacks.
- Wash and core the apples in advance.
- Mix the cinnamon seasoning shortly before cooking.
- Cook a batch and divide it into individual containers.
- Refrigerate the cooked apples promptly.
- Store walnuts separately to keep them crunchy.
- Reheat a portion when you are ready to serve.
If cutting the apples ahead of time, toss them with a little lemon juice and refrigerate them in a sealed container to help slow browning.
Common Mistakes to Avoid
Cutting the Apples Too Thin
Very thin slices can become mushy before the edges brown. Cut the apples into evenly sized wedges or slices.
Using Too Much Syrup
Excess syrup creates more liquid in the basket and can prevent the apples from caramelizing. Start with the recommended amount and add more only after cooking if needed.
Overcrowding the Air Fryer
A packed basket traps steam and produces softer apples. Cook in batches if necessary.
Adding Walnuts Too Early
Walnuts can burn before the apples finish cooking. Add them during the last few minutes or toast them separately.
Cooking at Too High a Temperature
High heat can darken the outside before the center becomes tender. A moderate temperature of 350°F gives the apples time to soften.
Forgetting to Check the Apples
Different apple varieties soften at different rates. Check the slices early and adjust the cooking time to match your preferred texture.
Frequently Asked Questions
Which apples work best for air frying?
