Ingredients:
- 3 pounds sweet potatoes
- 3 tablespoons unsalted butter
- 1/2 teaspoon salt
- 1/2 cup fresh orange juice
- 9 ounces crushed pineapple, drained
- 2.5 cups mini marshmallows
Preparation and Baking
Step 1: Prepare the Sweet Potatoes
First, we need to get our sweet potatoes ready for mashing. Begin extract by thoroughly washing your 3 pounds of sweet potatoes. You can either peel them before or after cooking, depending on your preference. If you choose to peel them beforehand, a sharp vegetable peeler will work wonders. Once peeled (or unpeeled, if you prefer a slightly more rustic texture), cut the sweet potatoes into roughly uniform chunks, about 1 to 1.5 inches in size. This ensures they cook evenly.
There are a couple of ways to cook the sweet potatoes until they are fork-tender. The most common and efficient method is boiling. Place the sweet potato chunks in a large pot and cover them generously with cold water. Add a pinch of salt to the water, which helps to season the potatoes as they cook. Bring the water to a rolling boil over medium-high heat, then reduce the heat to a simmer. Cook for about 15-20 minutes, or until a fork can be easily inserted into a piece with no resistance. Another option is to roast them. Toss the potato chunks with a little oil and spread them on a baking sheet, roasting at 400°F (200°C) for about 25-30 minutes, until tender. Whichever method you choose, drain the sweet potatoes very well if you boiled them. Excess water can make the casserole watery, so it’s worth taking a moment to ensure they are as dry as possible.
Step 2: Mash and Combine the Sweet Potato Base
Once the sweet potatoes are cooked and drained, it’s time to mash them. Transfer the hot sweet potato chunks into a large mixing bowl. Add the 3 tablespoons of unsalted butter, which should be softened slightly so it melts easily. Also, add the 1/2 teaspoon of salt to enhance the natural sweetness of the potatoes and balance the flavors. Using a potato masher or a sturdy fork, mash the sweet potatoes and butter until smooth and creamy. Don’t worry if there are a few small lumps; some texture is nice, but aim for a relatively smooth consistency.
Next, it’s time to incorporate the liquid and fruit elements that give this casserole its signature flavor. Pour in the 1/2 cup of fresh orange juice. The citrus brightens up the earthiness of the sweet potatoes beautifully. Then, add the 9 ounces of drained crushed pineapple. Make sure to drain the pineapple very well, as we don’t want any excess liquid from it either. The pineapple brings a delightful tropical sweetness and a bit of tangy texture. Stir everything together until all the ingredients are well combined and you have a cohesive, fragrant mixture. Taste the mixture at this point and adjust the salt if needed. The goal is a balanced sweet and savory flavor profile.
Step 3: Assemble the Casserole
Now that our sweet potato base is ready, we can assemble the casserole. Lightly grease a baking dish, approximately 9×13 inches, to prevent sticking. Spoon the sweet potato mixture into the prepared baking dish, spreading it evenly with the back of a spoon or a spatula. Ensure the surface is relatively smooth, creating an even layer for the marshmallows to melt over.
Step 4: Top with Marshmallows
This is the part where the magic happens and our Sweet Potato Marshmallow Casserole truly earns its name. Evenly scatter the 2.5 cups of mini marshmallows over the entire surface of the sweet potato mixture. Try to distribute them as uniformly as possible so you get that beautiful, gooey, golden-brown marshmallow topping in every bite. Don’t be shy; a generous layer of marshmallows is key to achieving that classic dessert-like quality.
Step 5: Bake and Brown
Preheat your oven to 350°F (175°C). Place the assembled casserole dish in the preheated oven. Bake for 20-25 minutes, or until the sweet potato mixture is heated through and the marshmallows are puffed ugin extractnd beginning to turn a lovely golden brown. Keep an eye on the marshmallows towards the end of the baking time, as they can go from perfectly golden to burnt very quickly. If the marshmallows start browning too fast but the casserole isn’t quite heated through, you can loosely tent the dish with aluminum foil. Once it’s out of the oven, let it stand for a few minutes before serving. This allows the casserole to set slightly, making it easier to scoop. The aroma filling your kitchen will be divine, promising a comforting and sweet treat.

Frequently Asked Questions about Sweet Potato Marshmallow Casserole:
Q1: Can I make Sweet Potato Marshmallow Casserole ahead of time?
Absolutely! You can prepare the sweet potato mixture and assemble the casserole (without the marshmallows) up to 24 hours in advance. Cover it tightly and refrigerate. When you’re ready to bake, add the marshmallows and bake as directed, allowing a little extra time for it to heat through.
Q2: What kind of marshmallows work best for this Sweet Potato Marshmallow Casserole?
For the classic gooey topping, regular large marshmallows are ideal. They melt beautifully and create that signature golden-brown crust. Mini marshmallows can also be used, but they tend to toast up more quickly and might require closer monitoring to prevent burning.
