Baked Apple Slices with Cinnamon

The smell of toasted cinnamon and melted brown sugar hitting a hot oven is the best part of autumn. I used to try making whole baked apples, but they always turned out like baby food or stayed raw in the center. It was a frustrating cycle of guessing games with the timer.

Then I tried slicing them. By changing the shape, everything changed. You get more surface area for the sugar to cling to, and the heat penetrates the fruit evenly. These Baked Apple Slices give you that cozy, nostalgic vibe but actually finish cooking before you lose your patience.

You can expect a treat that's tender but still has a bit of a bite. It's a simple win for anyone who wants something warm and comforting without spending three hours in the kitchen.

Easy Baked Apple Slices Tips

The trick here is all about the geometry of the fruit. When you use 1/4 inch rounds, the butter and sugar wrap around every edge, creating a glaze that thickens as the water evaporates.

Thin Cuts: Slicing the apples thin means they cook in 20 minutes instead of an hour. It prevents the outside from burning while the inside stays hard.

Acid Balance: The lemon juice isn't just for color. It cuts through the heavy brown sugar, making the fruit taste brighter and less like a syrup bomb.

Recipe Specs

I've found that a 9x13 inch pan is the sweet spot. If you crowd the apples too much, they steam instead of roast, which leads to a soggy mess. Keep them in a single layer, slightly overlapping, to get those caramelized edges.

Trust me on the temperature. 375°F (190°C) is high enough to bubble the sugar but low enough that it won't scorch the butter before the apples soften.

The Building Blocks

Choosing the right apple is the only part that really matters. I stick to Granny Smith for the tartness or Honeycrisp if I want them to hold their shape better. Avoid Red Delicious, as they tend to fall apart into a grainy texture.

For the full list, you'll need: - 4 large Granny Smith or Honeycrisp apples (approx. 2 lbs / 900g), peeled, cored, and sliced into 1/4 inch rounds Why this? Keeps the texture consistent across the pan - 2 tbsp lemon juice Why this? Prevents oxidation and balances sugar - 4 tbsp unsalted butter, melted Why this? Creates a rich, velvety base for the glaze - 1/4 cup light brown sugar, packed Why this? Molasses notes deepen the flavor - 1 tsp ground cinnamon Why this? The classic warming spice - 1/4 tsp ground ginger Why this? Adds a subtle, spicy kick - 1/4 tsp salt Why this? Makes the sugar pop

The Tool Kit

No fancy tools are necessary. You'll just need a 9x13 inch baking dish and a large bowl for the lemon soak. I find a silicone brush works best for the glaze, though a spoon is just as effective.

Try to keep your slices uniform in thickness. If they vary, the thinner pieces will turn jammy while the thicker ones stay crunchy.

From Prep to Plate

Now, let's get the process moving. Work quickly to ensure the apples don't sit out and brown.

1. Combine the apple slices and lemon juice in a large bowl. Note: Make sure every slice is coated to keep the color bright
2. Arrange the slices in a single layer within a 9x13 inch baking dish. Note: Overlap them like shingles for better coverage
3. In a small bowl, whisk together the melted butter, brown sugar, cinnamon, ginger, and salt. Note: Stir until the sugar is mostly dissolved
4. Pour the cinnamon glaze evenly over the arranged slices.
5. Brush the glaze into the edges of the slices. Note: This prevents the edges from drying out
6. Set the dish in the center of the oven.
7. Bake at 375°F (190°C) for 20-25 minutes.
8. Remove from the oven until the apples are tender and the glaze is bubbling and mahogany colored.

Chef's Note: If you have an air fryer, you can prepare these in a basket at 350°F for about 12-15 minutes. Just avoid shaking the basket too much so you don't break the slices.

Fixing Common Problems

Preventing Mushiness

If your Baked Apple Slices are too soft, you likely used a high moisture variety like a Gala. Stick with firm, tart apples instead. Also, double check your oven temperature, as too low a heat can result in steaming rather than roasting.

Keeping the Glaze from Scorching

Brown sugar can shift from caramelized to burnt very rapidly. If the edges start turning black before 20 minutes are up, place a sheet of foil over the dish. This preserves the heat while shielding the sugar from the oven's heating element.

Avoiding Soggy Slices

Certain apples release a significant amount of juice. If the pan appears too liquid, blot the moisture from the slices after the lemon soak but before adding the butter mixture. This helps the glaze adhere better.

Adjusting the Recipe

Feel free to customize this based on what you have on hand. For a healthier alternative, replace the brown sugar with a bit of maple syrup and a touch more cinnamon. It will be slightly thinner, but still delicious.

To add extra crunch, try a crumble topping. Combine 2 tbsp flour, 2 tbsp oats, and 1 tbsp cold butter, then sprinkle the mixture on top before baking. Since this adds more bulk, you may need to increase the cooking time by 5 minutes.

These pair beautifully with other fruit based desserts. For a more decadent option, try my Apple Doughnuts recipe for a weekend brunch.

Keeping Them Fresh

Keep remaining portions in a sealed container in the fridge, where they'll stay fresh for about 4 days. Note that the glaze will thicken as it cools, potentially resembling a jam more than a syrup.

These can be frozen for up to 2 months. To prevent them from fusing into one solid apple mass, freeze them individually on a parchment lined tray before moving them into a bag.

Don't throw away the apple peels. I typically simmer mine in a pot of water with a cinnamon stick; it's a quick way to fill your home with a cozy bakery aroma.

Ways to Serve

These are quite versatile. I enjoy them warm over a dollop of vanilla bean ice cream, where the chilled cream meets the hot mahogany glaze. For a breakfast treat, try them piled on Greek yogurt with a sprinkle of granola.

If you're serving these as a side dish, they pair wonderfully with roasted pork loin or a grilled cheese sandwich. The bright tartness of the fruit balances out the richness of the cheese.

For a more indulgent experience, you can drizzle some Caramel Apple Sauce over the top. This added layer of sweetness transforms a simple snack into a proper dessert.

There you have it. Just remember to keep the slices thin, the oven hot, and the apples tart. You'll have these Baked Apple Slices on the table in 30 minutes, though they'll taste like you spent all afternoon on them. Enjoy!
