Ingredients:
- 3 pounds sweet potatoes
- 3 tablespoons butter
- 1/2 teaspoon salt
- 1/2 cup orange juice
- 9 ounces crushed pineapple, drained
- 2.5 cups mini marshmallows
Preparing the Sweet Potatoes
The foundation of our delicious Sweet Potato Marshmallow Casserole starts with perfectly cooked sweet potatoes. To begin extract, wash your sweet potatoes thoroughly under cool running water. You can peel them if you prefer a smoother texture, but I often find leaving the skin on imparts a lovely rustic charm and extra nutrients. The key is to cut them into roughly equal-sized pieces, about 1-inch cubes. This ensures they cook evenly. You have a couple of options for cooking: boiling or roasting. For a quicker approach, place the cubed sweet potatoes in a large pot and cover them with cold water. Add a pinch of salt to the water to help season the potatoes as they cook. Bring the water to a boil over medium-high heat, then reduce the heat to a simmer and cook for about 15-20 minutes, or until the potatoes are fork-tender. You should be able to easily pierce them with a fork with little resistance. Drain them very well in a colander to remove as much excess water as possible, as this is crucial for achieving the right casserole consistency. Alternatively, you can roast the sweet potatoes. Toss the cubed sweet potatoes with a little bit of oil, salt, and pepper, spread them on a baking sheet, and roast at 400°F (200°C) for 25-30 minutes, or until tender and slightly caramelized. This roasting method adds a wonderful depth of flavor.
Mashing and Mixing the Base
Once your sweet potatoes are cooked and drained (whether boiled or roasted), it’s time to mash them. Transfer the hot sweet potatoes to a large mixing bowl. Add the 3 tablespoons of butter, which will melt into the warm potatoes, adding richness and helping to create a creamy texture. Add the 1/2 teaspoon of salt to enhance the overall flavor profile. Now, using a potato masher or a sturdy fork, mash the sweet potatoes until they are smooth and creamy. It’s important not to over-mash them into a paste; a little bit of texture is lovely. Next, we incorporate the liquid and fruit components. Pour in the 1/2 cup of orange juice. The citrusy brightness of the orange juice cuts through the sweetness of the potatoes and adds a subtle tang that complements the other flavors beautifully. Then, gently fold in the 9 ounces of drained crushed pineapple. Ensure the pineapple is well-drained to prevent the casserole from becoming too watery. The crushed pineapple adds little bursts of tropical sweetness and a pleasant texture contrast to the smooth sweet potato. Stir everything together until it is just combined. Be careful not to overmix at this stage, as we want to maintain some of the texture from the pineapple.
Assembling the Casserole
Now that our sweet potato mixture is ready, it’s time to assemble the casserole. Preheat your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish or a similar-sized casserole dish with butter or cooking spray. This step is important to prevent the casserole from sticking to the dish. Pour the prepared sweet potato mixture into the greased baking dish and spread it out evenly. Use the back of a spoon or a spatula to create a smooth, level surface. This ensures even cooking and a beautiful presentation. The casserole base should be about 1-1.5 inches thick.
The Marshmallow Topping
This is where the magic happens and our Sweet Potato Marshmallow Casserole truly earns its name. Evenly sprinkle the 2.5 cups of mini marshmallows over the entire surface of the sweet potato mixture. You want to ensure there are marshmallows distributed across the entire dish, edge to edge, for that delightful gooey topping. Don’t be shy with the marshmallows; they’re the star of this part!
Baking to Golden Perfection
Place the assembled casserole dish into the preheated oven. Bake for approximately 20-25 minutes, or until the sweet potato casserole is heated through and the marshmallows on top are puffed up, golden brown, and gloriously melted. Keep a close eye on the casserole during the last few minutes of baking, as marshmallows can go from perfectly toasted to burnt very quickly. If you notice the marshmallows browning too fast but the casserole isn’t quite heated through, you can loosely tent the dish with aluminum foil for the remaining baking time. The goal is a warm, bubbly casserole with a luscious, melted marshmallow topping.
Resting and Serving
Once the Sweet Potato Marshmallow Casserole is out of the oven, it’s tempting to dig in immediately, but a short resting period is highly recommended. Let the casserole sit for about 5-10 minutes before serving. This allows the flavors to meld further and the marshmallows to set slightly, making it easier to scoop and serve. Serve warm as a delightful side dish alongside your favorite holiday meals, roasted meats, or any occasion that calls for a touch of comforting sweetness.

Frequently Asked Questions:
Q: Can I make the Sweet Potato Marshmallow Casserole ahead of time?
A: Absolutely! You can prepare the sweet potato mixture and assemble the casserole up to a day in advance. Cover it tightly and refrigerate. When you’re ready to bake, allow it to sit at room temperature for about 30 minutes before baking, and you may need to add a few extra minutes to the cooking time. Add the marshmallows just before baking to prevent them from getting too hard.
Q: My marshmallows are browning too quickly. What can I do?
A: If your marshmallows are browning too fast, you can loosely tent the casserole with aluminum foil during the last 10-15 minutes of baking. This will shield them from direct heat while allowing the casserole to heat through properly. Keep an eye on it, and remove the foil once the marshmallows are golden and the casserole is bubbly.
