How to Make Classic Sweet Potato Casserole
Making this classic sweet potato casserole is a delightful journey that fills your kitchen with warmth and delicious aromas. Follow these simple steps, and you’ll have a dish that’s sure to impress!
Step 1: Preheat the Oven
First things first, preheat your oven to 350°F (175°C). Preheating is crucial because it ensures even cooking. You want that casserole to bake perfectly, not just warm up. So, let your oven do its thing while you prepare the rest!

Step 2: Prepare the Sweet Potato Mixture
In a large bowl, combine your mashed sweet potatoes, brown sugar, milk, melted butter, eggs, vanilla extract, cinnamon, and nutmeg. Mix everything until it’s smooth and creamy. This is where the magic begins! The sweet potatoes should be velvety, and the spices will create a comforting aroma that makes your mouth water.

Step 3: Transfer to Baking Dish
Next, grab a greased baking dish. Greasing is essential to prevent sticking and make serving easier. Pour the sweet potato mixture into the dish, spreading it evenly. This ensures that every bite is just as delicious as the last. Trust me, no one wants a lopsided casserole!

Step 4: Create the Topping
In a separate bowl, mix the chopped pecans with brown sugar. This crunchy topping is what makes this classic sweet potato casserole stand out! Sprinkle it generously over the sweet potato mixture. The combination of the sweet, nutty pecans with the creamy base is simply irresistible.

Step 5: Add Optional Marshmallows
If you’re feeling adventurous, add mini marshmallows on top. This step is optional, but it adds a fun, gooey sweetness that many love. It’s like a little surprise in every bite! Just sprinkle them on before baking, and they’ll melt into a delightful topping.

Step 6: Bake to Perfection
Now, it’s time to bake! Place your casserole in the preheated oven and let it bake for 30-35 minutes. Keep an eye on it; you want the topping to be golden brown and the casserole heated through. A toothpick inserted in the center should come out clean. Once it’s done, let it cool slightly before serving. Your guests will be lining up for seconds!
