Sweet Potato Casserole Ingredients
For the Casserole
- Sweet Potatoes – The star of the dish, lending a creamy and naturally sweet flavor; canned sweet potatoes can be used, but make sure they are well-drained.
- Brown Sugar – Adds a rich caramel sweetness; if you prefer, white sugar works, but it won’t add the same depth of flavor.
- Pecans – Provides a delightful crunch and nutty flavor; walnuts can be substituted, or leave out for nut-free options.
- Eggs – Essential for binding the mixture and contributing to its fluffy texture; an egg replacement can be used for a vegan version.
- Milk – Adds creaminess to the filling; feel free to use non-dairy milk for a lactose-free option.
- Unsalted Butter – Enhances the rich flavor; for a dairy-free alternative, margarine works well.
- Vanilla Extract – Infuses a sweet warmth into the dish, enhancing its overall flavor.
- Cinnamon & Nutmeg – These spices provide the warm notes that are essential for creating that classic holiday taste.
For the Topping
- Mini Marshmallows – Adds a gooey sweetness to the dish’s finish; can be swapped with crushed graham crackers for a crunchy twist.
- Flour – Used in the cinnamon filling to create a crumbly topping; whole wheat flour can be a hearty alternative.
- Additional Brown Sugar – Enhances the topping’s sweetness and caramelization; consider using less if you’d like a lighter topping.
This Sweet Potato Casserole is a wonderful blend of flavors and textures that will delight your holiday guests!
How to Make Sweet Potato Casserole
-
Preheat Oven: Start by preheating your oven to 350°F. While it’s warming up, prepare your casserole dish by greasing it with butter or non-stick spray for easy release.
-
Roast Pecans: Spread the pecans on a baking sheet and roast them for about 5-7 minutes, until they become fragrant and slightly golden. Chop them roughly once cooled.
-
Cook Sweet Potatoes: Boil the peeled and cubed sweet potatoes in salted water for about 15 minutes, or until they are fork-tender. Drain them well and mash until smooth.
-
Prepare Filling: In a mixing bowl, combine the mashed sweet potatoes with brown sugar, melted butter, beaten eggs, milk, vanilla extract, cinnamon, and nutmeg. Stir until everything is nicely blended and smooth.
-
Make Cinnamon Filling: In a separate bowl, mix together flour, brown sugar, and a pinch of cinnamon until crumbly. This will be sprinkled on top for that delicious crunch.
-
Assemble Casserole: Layer half of the sweet potato mixture in your greased dish, sprinkle half of the cinnamon filling, add the remaining sweet potato mix, and finish by topping it with the pecans and mini marshmallows.
-
Bake: Place the casserole in the preheated oven and bake for about 30 minutes, or until heated through and the topping is golden brown. If the marshmallows start to brown too quickly, cover the dish with foil.
-
Serve: Once baked, let the casserole rest for a few minutes to set before serving warm to your eager guests.
Optional: Drizzle with warm caramel sauce for an extra indulgent touch!
