Step-by-Step Instructions

Step 1: Prepare the Sweet Potatoes

Begin by peeling and chopping your sweet potatoes into cubes. Boil them in salted water for about 15-20 minutes until tender. Drain and mash well until there are no lumps remaining.

Step 2: Mix the Base

In a spacious mixing bowl, combine the mashed sweet potatoes with granulated sugar, milk, vanilla extract, cinnamon, nutmeg, and melted butter. Add the eggs one at a time, mixing thoroughly until everything is well combined and smooth.

Step 3: Transfer and Top

Pour the sweet potato mixture into a greased baking dish. Top generously with mini marshmallows, allowing them to ooze over the edges for that perfect toasted look.

Step 4: Bake

Preheat your oven to 350°F (175°C) and bake your casserole for 30 minutes, or until the marshmallows are golden brown and puffed up. Keep a close eye on them to avoid burning!

Step 5: Serve and Enjoy

Healthier Alternatives for the Recipe

Serving Suggestions

Common Mistakes to Avoid

To ensure the best outcome, watch out for these pitfalls:

• Overcooking sweet potatoes: This makes them watery and grainy. Aim for tender but not mushy sweet potatoes.
• Under-mixing the batter: A lumpy mixture will yield uneven textures. Mix until just combined.
• Neglecting the oven temperature: Ensure your oven is preheated for even cooking.

Storing Tips for the Recipe

If you find yourself with leftovers (which is often the case!), here’s how to store them wisely:

• Refrigerate: Cover the dish with plastic wrap or transfer to an airtight container. It can last in the fridge for up to 3 days.
• Freeze: For longer storage, freeze the casserole before baking. It can be kept for up to 2 months. When ready to enjoy, thaw in the fridge overnight and bake as directed.
