Old Fashioned apple slices recipe with oat crumble on top. With cinnamon and sugar baked on a sheet pan. This is like our Instant Pot Apple Crisp, a fun fruit dessert that is a family favorite sweet treat, but low and slow to become tender with every bite.
If you love a good sheet pan dessert this is the one for you!! Using fresh fruit and oats to create a sweet crunch on top, it is a bit like the inside of an apple pie without the crust! With Granny Smith or Fuji sliced and baked until tender your family will love this treat. (post may contain affiliate links present)
Sliced Apples in the Oven with Oats
Yes we are obsessed with our Crockpot Apple Crisp but it isn’t really crispy at all on top. Steamed, the texture is like apple pie filling but the crumble remains soft. This way you can get that same wonderfulness but with a bit of crunch as well. All made on one tray, line with parchment for an easier cleanup too.
Cinnamon baked Apples with Brown Sugar can have other things added to it too though. Think raisins and/or a handful of dried cranberries in there too. Have leftover cranberries after the holidays? Another great idea as they will soften and burst releasing all those juices on the tray with everything else too.
I have made this in individual servings in mugs before too. This is best if you are serving a larger crowd, and could be cut in half for less of them, but for an individual method you’d need to use our air fryer Ninja Foodi Apple Crisp instructions instead. For this one you will use;
Ingredients
- 12 Granny Smith apples are best, peeled, cored and sliced
- Brown sugar is the sweetness
- 2 tsp cinnamon is a must
- 1 c all purpose flour creates the crumble
- Butter cut into small pieces or dairy free alternative works
- 1.5 c old fashioned oats, not instant
- Walnuts chopped are great, but optional
- Maple syrup or agave nectar could be used too
- 1 tsp vanilla
- 1/2 tsp salt
- And if you want vanilla icing or scoop of vanilla ice cream on top you might want those
To make these on the stove you would want to take a peek at our Cast Iron Apple Crisp with Oats version. All are great fresh served warm and save well too in the fridge. Make sure it is in an airtight container and reheat within 3-4 days.
To make Scalloped Apples you have to start with the slicing. It is a simple process, but there are a few different methods you can use. Whether you want to remove the skin or not needs to be decided first. It is easier to peel the apples while they are whole using a vegetable peeler or a paring knife.
Rinse under cool running water to remove any dirt. Place a cutting board on a stable surface, and make sure it doesn’t wobble or move while you’re slicing. Do this to make our Apple Kugel too which is also delish.
How to Slice an Apple
- Hold firmly with one hand and use a sharp knife to slice off both ends (top and bottom). This creates a stable base for slicing.
- To remove the core, you can use one of the following methods:
- If you have an apple corer, align it with the center of one of the apple halves and press down to remove the core.
- Don’t have an apple corer? You can use a knife. Hold one of the apple halves with the cut side facing down, then angle the knife slightly to cut around the core. Repeat on the other half.
- While standing upright on one of the flat ends you created earlier, use the knife to cut it vertically down the center. This will give you two equal halves.
Once the core is removed, you can slice into your desired thickness. For this you would want medium thick slices where as for Baked Apple Fritters I would prefer diced.
If you wanted to use similar ingredients but in more of a cake consistency, we love that too. Apple Cobbler with Cake Mix would be the directions to follow for something like that.
How to Bake Old Fashioned Apple Slices with Oat Crumble in the Oven
- Preheat your oven to 350 degrees F (175 degrees C) and grease baking sheet. In a large bowl, combine the apple wedges.
- Sprinkle 1 teaspoon of cinnamon and the brown sugar over the apples, then toss to coat.
- Add ½ cup of flour to the apples and mix thoroughly.
- Spread this apple mixture onto the prepared baking sheet. In another bowl, place the remaining ½ cup of flour. Using 2 knives or a pastry blender, cut in the cold butter until the mixture resembles small peas.
- Add the other teaspoon of cinnamon, rolled oats, chopped walnuts, maple syrup, vanilla extract, and salt. Stir the mixture until it is well combined.
- Carefully spoon the oat and walnut mixture over the apples on the baking sheet, evenly distributing it.
Bake the apple dessert in your baking dish in the preheated oven for approximately 45 to 50 minutes, or until the fruit mixture is bubbling, top is lightly browned and fruit is as tender as you’d like it to be.
