Ingredients:
- For the Sweet Potato Layer:
- 4 large sweet potatoes (about 3 pounds), peeled and cubed
- 1/2 cup unsweetened applesauce
- 1/4 cup maple syrup
- 1/4 cup coconut milk (full-fat, canned)
- 2 tablespoons coconut oil, melted
- 1 teaspoon vanilla extract
- 1/2 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/4 teaspoon salt
- For the Gluten-Free Crumble Topping:
- 1 cup gluten-free oat flour
- 1/2 cup almond flour
- 1/2 cup chopped pecans or walnuts
- 1/4 cup packed brown sugar
- 1/4 cup coconut oil, melted
- 1/4 teaspoon ground cinnamon
- 1/4 teaspoon salt
Preparing the Sweet Potato Layer:
- Cook the Sweet Potatoes: The first thing we need to do is get those sweet potatoes nice and soft. You have a couple of options here. You can either boil them or bake them. I prefer boiling because it’s quicker. Place the peeled and cubed sweet potatoes in a large pot and cover them with water. Bring to a boil over high heat, then reduce the heat to medium and simmer for about 15-20 minutes, or until the sweet potatoes are fork-tender. They should be easily pierced with a fork. If you prefer baking, preheat your oven to 400°F (200°C). Toss the cubed sweet potatoes with a tablespoon of coconut oil and spread them out on a baking sheet. Bake for 30-40 minutes, or until they are very soft.
- Drain and Mash: Once the sweet potatoes are cooked, drain them well if you boiled them. If you baked them, just transfer them to a large bowl. Now, it’s time to mash! You can use a potato masher, an electric mixer, or even a food processor for this. I like using an electric mixer because it makes the sweet potatoes super smooth and creamy. If you’re using a food processor, be careful not to over-process them, or they can become gummy.
- Add the Remaining Ingredients: To the mashed sweet potatoes, add the applesauce, maple syrup, coconut milk, melted coconut oil, vanilla extract, cinnamon, nutmeg, and salt. Mix everything together until it’s well combined and smooth. Taste and adjust the seasonings as needed. If you like it sweeter, add a little more maple syrup. If you want more spice, add a pinch more cinnamon or nutmeg.
Making the Gluten-Free Crumble Topping:
- Combine Dry Ingredients: In a medium bowl, whisk together the gluten-free oat flour, almond flour, chopped pecans or walnuts, brown sugar, cinnamon, and salt. Make sure everything is evenly distributed.
- Add the Coconut Oil: Pour the melted coconut oil over the dry ingredients. Use a fork or your fingers to mix everything together until it forms a crumbly mixture. The mixture should be moist enough to hold together slightly when you pinch it, but still crumbly. If it seems too dry, you can add a teaspoon or two more of melted coconut oil.
Assembling and Baking the Casserole:
- Preheat the Oven: Preheat your oven to 350°F (175°C).
- Prepare the Baking Dish: Lightly grease an 8×8 inch baking dish with coconut oil or cooking spray. You can also use a 9-inch pie plate if you prefer.
- Layer the Sweet Potato Mixture: Pour the sweet potato mixture into the prepared baking dish and spread it out evenly.
- Add the Crumble Topping: Sprinkle the gluten-free crumble topping evenly over the sweet potato layer. Make sure to cover the entire surface.
- Bake: Bake in the preheated oven for 30-35 minutes, or until the topping is golden brown and the sweet potato mixture is bubbly around the edges. Keep an eye on it towards the end of the baking time to make sure the topping doesn’t burn. If it starts to brown too quickly, you can loosely cover the casserole with aluminum foil.
- Cool and Serve: Once the casserole is done, remove it from the oven and let it cool for at least 15-20 minutes before serving. This will allow the sweet potato mixture to set up a bit and prevent it from being too runny. You can serve it warm or at room temperature. It’s delicious on its own, or you can top it with a dollop of coconut whipped cream or a sprinkle of extra pecans.
Tips and Variations:
- Sweetness Level: Adjust the amount of maple syrup to your liking. If you prefer a less sweet casserole, you can reduce the amount of maple syrup to 1/8 cup. If you like it sweeter, you can increase it to 1/3 cup.
- Nut Options: Feel free to use any nuts you like in the crumble topping. Walnuts, pecans, almonds, or even a combination of nuts would work well. You can also omit the nuts altogether if you have a nut allergy.
- Spice Variations: Experiment with different spices to customize the flavor of the casserole. You can add a pinch of ground ginger, allspice, or cloves to the sweet potato mixture or the crumble topping.
- Coconut Flavor: If you’re not a fan of coconut, you can substitute the coconut milk with regular milk or cream. You can also use butter instead of coconut oil in the crumble topping.
- Make-Ahead Option: You can prepare the sweet potato layer and the crumble topping ahead of time and store them separately in the refrigerator. When you’re ready to bake the casserole, simply assemble it and bake as directed.
- Freezing Instructions: This casserole can be frozen for up to 2 months. Let it cool completely before wrapping it tightly in plastic wrap and then in aluminum foil. To thaw, place it in the refrigerator overnight. You can reheat it in the oven at 350°F (175°C) until it’s warmed through.
- Vegan Option: This recipe is already naturally vegan if you ensure your brown sugar is vegan-friendly (some are processed with bone char).
- Adding a Marshmallow Topping (Not Gluten-Free): If you’re not concerned about keeping the recipe gluten-free, you can add a marshmallow topping during the last 5-10 minutes of baking. Simply sprinkle mini marshmallows over the crumble topping and bake until they are golden brown and slightly melted.
Serving Suggestions:
This Gluten-Free Sweet Potato Casserole is a perfect side dish for Thanksgiving, Christmas, or any special occasion. It also makes a delicious and comforting weeknight meal. Serve it alongside roasted turkey, ham, chicken, or a vegetarian main course. It pairs well with other holiday favorites like green bean casserole, cranberry sauce, and stuffing.
