Simple Ingredients List
People need these items to make sweet potato casserole:
Main Part:
- 3 pounds sweet potatoes
- 1/2 cup butter (melted)
- 2 eggs
- 1/2 cup brown sugar
- 1/4 cup milk
- 1 teaspoon vanilla
- 1 teaspoon cinnamon
- 1/4 teaspoon nutmeg
- 1/2 teaspoon salt
Topping Choice 1 – Marshmallows:
- 3 cups mini marshmallows
Topping Choice 2 – Nuts:
- 1/2 cup flour
- 1/2 cup brown sugar
- 1/4 cup cold butter (cut into pieces)
- 1 cup chopped pecans
Easy Steps to Make It
Step 1: Cook the Sweet Potatoes
Turn oven to 400 degrees. Wash sweet potatoes with water.

Dry them with paper towels.
Take a fork and poke holes all over each potato. This keeps them from breaking open in the oven. Put potatoes on a baking sheet.

Bake for 45 to 60 minutes. Press them gently to check if they’re soft. Big potatoes take longer to cook. Let them cool down before touching them.
Step 2: Make the Mix
Turn oven down to 350 degrees. Cut open the sweet potatoes. Take out all the orange part and put it in a big bowl. Throw away the skins.
Mash the sweet potatoes until smooth. People can use a potato masher or electric mixer. Keep mashing until there are no bumps left.

Add melted butter and mix well. Then add eggs, brown sugar, milk, vanilla, cinnamon, nutmeg, and salt. Stir everything until it looks smooth and creamy.

Step 3: Pick a Topping
For marshmallow topping: Just measure the mini marshmallows and keep them ready.
For nut topping: Mix flour and brown sugar in a bowl. Add cold butter pieces. Use a fork to mix until it looks like crumbs. Add chopped pecans and stir.

Step 4: Put Everything Together
Spray a 9×13 inch pan with cooking spray. Put the sweet potato mix in the pan. Spread it out evenly. Make the top flat with a spoon.
Add the topping. Sprinkle marshmallows all over the top. Or spread the nut mixture across the whole surface.

Step 5: Bake Until Done
Put the pan in the oven for 20 to 25 minutes. It should be hot all through and golden brown on top.

Watch marshmallows carefully at the end. They can burn quickly. If the top gets too brown, cover with foil.
Let it sit for 5 minutes before serving. This helps it stay together when people cut pieces.

Good Tips to Remember
Choose Good Sweet Potatoes: Look for ones that feel heavy and firm. Don’t buy any with soft spots or cuts.
Don’t Make It Watery: Always bake sweet potatoes whole. Don’t boil them in water because that makes the dish watery.
Make It Smooth: For the smoothest texture, push mashed sweet potatoes through a strainer. This takes out any strings.
Make It Early: People can make this dish the day before. Just don’t put the topping on until ready to bake. Keep it in the fridge covered.
Check Temperature: If baking cold casserole, add 10 more minutes to cooking time.
Problems People Have and How to Fix Them
Too Much Water in Casserole This happens when sweet potatoes have too much water. Always bake them instead of boiling them.
Lumps in the Mix Not mashing enough causes this problem. Use an electric mixer or push everything through a strainer.
Burned Top Marshmallows brown very fast. Watch them closely and cover with foil if needed.
Too Sweet or Not Sweet Enough Sweet potatoes are different. Some are sweeter than others. Taste the mix before baking and add more salt or sugar if needed.
Takes Too Long to Cook Make sure oven is hot enough. Check that the middle gets hot before taking it out.
Different Ways to Make It
Healthier Version: Use Greek yogurt instead of some butter. Try honey instead of brown sugar. Add walnuts for good fats.
Spicy Version: Add a tiny bit of hot pepper powder. This makes the sweet taste even better.
Coconut Style: Mix in coconut flakes. Use toasted coconut on top instead of marshmallows.
Adult Version: Add one spoon of bourbon or rum to the mix. This is popular in the South.
