Sweet Potato and Apple Casserole with Cinnamon Crumb Topping

Hi, I’m Chef Emma! In my family, the debate between sweet and savory side dishes is always a lively one, especially around the holidays. This Sweet Potato and Apple Casserole is the delicious compromise that makes everyone happy.

It brings together the earthy richness of sweet potatoes with the tart, crisp sweetness of seasonal apples.​

I love this dish because it feels like a warm hug on a cold day. The pillowy soft potatoes and tender apples are baked under a golden, buttery cinnamon-oat crumb topping that adds the perfect crunch. It’s sweet enough to feel like a treat but wholesome enough to serve alongside your roast turkey or glazed ham. Plus, the aroma of cinnamon baking in the oven instantly makes the whole house feel festive!​

Equipment

Method

 

1. Boil Potatoes: Place the sweet potato chunks in a large pot of water. Bring to a boil and cook for 15-20 minutes until fork-tender. Drain well.
2. Mash Base: Return potatoes to the pot. Add 1/4 cup butter, 1/4 cup brown sugar, maple syrup, vanilla, and salt. Mash until smooth and creamy.
3. Assemble Layers: Spread the mashed sweet potatoes evenly into a greased 9×13 inch baking dish. Arrange the sliced apples in an even layer on top of the potatoes.
4. Make Crumble: In a medium bowl, whisk together the flour, oats, remaining 1/4 cup brown sugar, cinnamon, and nutmeg. Melt the remaining 1/4 cup butter and pour it over the dry ingredients. Mix with a fork until crumbly.
5. Top & Bake: Sprinkle the crumble mixture generously over the apples. Bake at 375°F (190°C) for 35-40 minutes, or until the apples are tender and the topping is golden brown.
6. Serve: Let cool for 10 minutes before serving to allow the filling to set slightly.

Notes

If the topping browns too quickly, cover loosely with foil for the last 10 minutes of baking.

Tips and Variations for Sweet Potato Apple Casserole

• Apple Choice Matters: Use a firm, slightly tart apple like Granny Smith or Honeycrisp. They hold their shape well during baking and provide a nice contrast to the soft sweet potatoes.marleysmenu​
• Make it Nutty: If your family loves crunch, mix ½ cup of chopped pecans or walnuts into the crumb topping for extra texture and flavor.sallysbakingaddiction+1​
• Prep Ahead: You can boil the potatoes and assemble the base layer a day in advance. Keep the crumb topping in a separate container and sprinkle it on just before baking so it stays crisp.
• Vegan Option: Swap the butter for melted coconut oil or a plant-based butter alternative. The coconut oil adds a subtle, tropical sweetness that pairs beautifully with the cinnamon.averiecooks​
