Ingredients for Sweet Potato Casserole with Marshmallows
To whip up this delightful Sweet Potato Casserole with Marshmallows, you’ll need the following ingredients:
- 4 cups sweet potatoes, mashed (you can use fresh or canned, but fresh adds a lovely flavor)
- 1/2 cup brown sugar (feel free to adjust this based on your sweetness preference)
- 1/4 cup milk (I like to use whole milk for extra creaminess, but any milk will do)
- 1/4 cup butter, melted (make sure it’s melted, as this helps everything blend together nicely)
- 1 teaspoon vanilla extract (this adds a lovely depth of flavor)
- 1/2 teaspoon cinnamon (oh, the warm spice that makes it feel like home!)
- 2 cups mini marshmallows (these are the crowning glory of your casserole, so don’t skimp!)
Gather these ingredients together, and you’re on your way to creating a dish that’ll make your taste buds dance! The combination of sweet potatoes with that gooey, toasted marshmallow topping is just divine. Trust me, it’s worth every step!
How to Prepare Sweet Potato Casserole with Marshmallows
Now, let’s dive into the steps for making this delicious Sweet Potato Casserole with Marshmallows! It’s easier than you think, and I promise you’ll be so proud of the result. Just follow along!
Step 1: Preheat the Oven
First things first: preheat your oven to 350°F (175°C). Preheating is super important because it ensures that your casserole cooks evenly from the moment it goes in. You don’t want to start baking it in a cold oven, as that can lead to uneven cooking and texture. So, set that temperature and let your oven do its magic while you prepare the rest of the ingredients!
Step 2: Mix the Ingredients
In a large mixing bowl, combine your 4 cups of mashed sweet potatoes, 1/2 cup of brown sugar, 1/4 cup of milk, 1/4 cup of melted butter, 1 teaspoon of vanilla extract, and 1/2 teaspoon of cinnamon. I like to use a hand mixer for this, but you can definitely use a spatula or a whisk if you prefer. Just mix it until everything is well blended and creamy. You want that gorgeous, sweet, spiced mixture that smells heavenly!
Step 3: Prepare the Baking Dish
Next, grab a greased baking dish—about 9×13 inches works perfectly. I usually just use a bit of butter or cooking spray to coat the bottom and sides. This helps ensure that your casserole doesn’t stick and makes for easy serving later. Pour that sweet potato mixture into the dish and spread it out evenly with a spatula. You want it nice and smooth!
Step 4: Add the Marshmallows
Now comes the fun part—topping it off! Sprinkle 2 cups of mini marshmallows evenly over the sweet potato layer. You want those little guys to be spread out so every bite gets that delightful marshmallow goodness. Go ahead and be generous; we all know it’s the marshmallows that make this dish so irresistible!
Step 5: Bake the Casserole
Finally, pop your casserole into the preheated oven and bake for about 25-30 minutes. Keep an eye on it! You’re looking for the marshmallows to puff up and turn that gorgeous golden brown color. Once they do, it’s time to take it out and let it cool for a few minutes before serving. The aroma that fills your kitchen during baking is simply magical, and trust me, your family will come running!

Tips for Success
To ensure your Sweet Potato Casserole with Marshmallows turns out perfectly every time, here are some pro tips that I swear by:
- Adjust Sweetness: Don’t hesitate to tweak the brown sugar based on your taste or the sweetness of your sweet potatoes. Sometimes, I use a little less sugar if my sweet potatoes are particularly sweet.
- Even Baking: Make sure to spread the sweet potato mixture evenly in the baking dish to ensure uniform cooking. This helps every bite be just as delicious as the last!
- Golden Marshmallows: Keep an eye on those marshmallows! If they start browning too quickly, you can cover the casserole with foil to prevent burning while the sweet potatoes finish heating through.
- Let It Rest: Allow the casserole to cool for a few minutes after baking. This helps the flavors settle and makes serving easier.
With these tips, you’ll be on your way to a truly delightful dish that will impress everyone at the table!
Storage & Reheating Instructions
After enjoying your Sweet Potato Casserole with Marshmallows, you might have some delicious leftovers (if you’re lucky!). To store it properly, let the casserole cool completely, then cover it tightly with aluminum foil or transfer it to an airtight container. It can stay in the refrigerator for up to 3-4 days.
When you’re ready to enjoy it again, reheating is a breeze! Preheat your oven to 350°F (175°C) and place the casserole in a baking dish, covered with foil to prevent the marshmallows from burning. Heat it for about 20-25 minutes, or until warmed through. If you want those marshmallows to be extra gooey and toasted, uncover it for the last 5-10 minutes of reheating. Trust me, the comforting aroma will remind you why this dish is such a beloved favorite!
