How to Make Sweet Potato Casserole
Preheat the oven to 400 °F. Start by piercing the sweet potatoes all over with a fork, then place them on a foil or parchment-lined baking sheet. Bake them until tender, around 45 minutes.
Cool and scoop the cooled potatoes. Once the potatoes are cool enough to handle, slice them open and scoop the flesh into a large mixing bowl, discarding the skins. Mash them with a potato masher, being careful not to over-mash for a smooth texture.
Combine the base ingredients. Add the milk, pure maple syrup, eggs, vanilla extract, fine sea salt, and ground nutmeg into the mashed sweet potatoes. Stir until just combined, creating a creamy mixture.
Mix the topping ingredients. In a small bowl, combine the all-purpose flour and butter, cutting the butter into the flour with the back of a fork. Stir in the brown sugar and chopped pecans until fully combined to create a crumbly topping.
Spread the sweet potato mixture into a 13 by 9-inch baking dish. Smooth the surface gently with a spatula, ensuring an even layer for a perfect bake.
Sprinkle the pecan topping. Lay the pecan mixture over the sweet potatoes in diagonal rows, leaving a 1 1/2-inch gap between each row for that delightful texture.
Bake the casserole. Pop it into the oven at 350 °F and bake until the top becomes golden brown, which should take about 30 minutes.
Add the marshmallows. Remove the casserole from the oven and gently place miniature marshmallows between the rows of pecan topping for that sweet, gooey finish.
Final Bake. Bake it again for an additional 10 minutes, or until the marshmallows turn just golden brown. Finally, it s time to serve your delicious Sweet Potato Casserole!
Optional: Top with a sprinkle of cinnamon for an extra warm flavor.

Expert Tips for Sweet Potato Casserole

Egg Temperature Matters: Use room temperature eggs for a smoother mix. Cold eggs can result in clumps in your batter.
Topping Technique: Sprinkle the pecan topping with space for even distribution. This prevents overly sweet sections and enhances texture.
Watch the Marshmallows: Keep an eye on the marshmallows in the final bake they can go from fluffy to burnt quickly!
Customize Your Nuts: Feel free to substitute pecans with other nuts like walnuts for a unique twist in your sweet potato casserole.
