Step-by-Step Cooking Instructions
Start by preheating your oven to 350 degrees Fahrenheit. This gives you enough time to prepare everything else while your oven reaches the right temperature.
Begin by peeling the sweet potatoes and cutting them into medium-sized chunks. Place them in a large pot of water and bring to a boil. Let them cook for about 15 to 20 minutes until they are fork-tender. Once cooked, drain the water and transfer the potatoes to a mixing bowl.
Mash the sweet potatoes until they are smooth and creamy. You can use a potato masher, fork, or a hand mixer depending on your preferred texture. Add the butter, brown sugar, eggs, vanilla extract, milk, salt, and cinnamon if you are using it. Mix everything together until the mixture is well combined and fluffy.
Grease a 9 by 13 inch baking dish with a bit of butter or nonstick spray. Pour the sweet potato mixture into the dish and spread it out evenly using a spatula.
Now it is time to prepare the topping. In a separate bowl, combine the chopped pecans, flour, brown sugar, and melted butter. Mix until the ingredients form a crumbly topping. Sprinkle this evenly over the sweet potato layer. If you love marshmallows, you can either add them now or wait until halfway through baking for a gooey golden topping.
Place the dish in the oven and bake for 25 to 30 minutes. The topping should turn a light golden brown and the casserole should be hot and bubbling around the edges. If you added marshmallows, watch closely to prevent them from burning.
Remove from the oven and let it cool for a few minutes before serving. This allows the casserole to set and makes it easier to serve.

Tips for Customizing the Recipe

One of the great things about sweet potato casserole is how flexible it is. You can easily adjust the ingredients to fit your taste, dietary needs, or whatever you have in your pantry.
If you prefer a healthier version, reduce the amount of sugar in both the base and the topping. You can also swap out butter for coconut oil or olive oil. For a dairy-free option, use plant-based milk like almond or oat milk and choose vegan butter or coconut cream.
To make the recipe vegan, replace the eggs with flax eggs or applesauce. The flavor will remain delicious and you will still get that creamy texture.
If you are serving people with nut allergies, skip the pecans and use a topping made from oats and seeds instead. It will still provide a lovely crunch.
Add some spices like nutmeg or ginger if you want a more festive flavor. For an extra decadent twist, sprinkle in some mini chocolate chips.
