- Pecan Streusel: A more nutty, crunchy variation that adds a deeper texture.

Step-by-Step Instructions for Sweet Potato Casserole
1. Prepare the Sweet Potatoes
The first step to creating the perfect Sweet Potato Casserole is cooking the sweet potatoes until they’re soft and mashable. You can either:
- Boil: Peel and chop the sweet potatoes into chunks, then boil them in water for 10-15 minutes or until soft.
- Bake: Pierce the sweet potatoes with a fork and bake them in the oven at 400°F (200°C) for about 45-60 minutes until tender.
Once the sweet potatoes are ready, let them cool slightly before peeling away the skin.
2. Mash the Sweet Potatoes
Once the sweet potatoes are cooked, mash them using a potato masher or a hand mixer until smooth. You can add a pinch of salt and a dash of cinnamon for flavor at this stage.
3. Make the Casserole Mixture
To your mashed sweet potatoes, add the melted butter, brown sugar, eggs, vanilla extract, milk, cinnamon, and nutmeg. Mix everything together until it’s well combined. The result should be a creamy, slightly thick mixture.
4. Assemble the Casserole
Transfer the sweet potato mixture into a greased 9×13-inch baking dish. Smooth the top with a spatula to make sure it’s evenly spread out.
5. Add the Topping
Now it’s time to add your topping. Whether you’re using marshmallows, a pecan streusel, or something else, spread it generously on top of the casserole. If you’re using marshmallows, make sure they cover the top completely.
6. Bake
Place the casserole in the oven at 350°F (175°C) and bake for 25-30 minutes, or until the topping is golden and bubbly. For marshmallows, bake until they turn golden brown. For a pecan topping, bake until the nuts are toasted and the casserole is set.
Tips for the Best Sweet Potato Casserole
Achieving the Perfect Texture
- Smoothness: Ensure the sweet potatoes are cooked long enough to be soft and easy to mash. The smoother the mixture, the creamier the casserole.
- Avoid Overmixing: When incorporating the eggs, be sure not to overmix the mixture to prevent it from becoming too dense.
Flavor Enhancements
- More Spice: If you love the warm flavor of spices, feel free to add a little extra cinnamon, ginger, or even a hint of allspice for a more aromatic dish.
- Adding Citrus: A teaspoon of orange zest can add a fresh, tangy flavor that complements the sweetness of the potatoes.
Make-Ahead Instructions
- Prep in Advance: You can prepare the casserole a day or two ahead. Simply make the casserole mixture, cover it with plastic wrap, and refrigerate. When you’re ready to bake, just add the topping and bake as usual.
- Freezing: If you need to make it ahead of time, freeze the unbaked casserole. Before baking, let it thaw overnight in the refrigerator.
