This recipe goes beyond the delightful mix of sweet and savory flavors; it embodies tradition and celebrates the magic of simple ingredients.

As we chatted in her warm, inviting kitchen, she shared childhood stories and recipes passed down through generations. That night, she decided to teach me one of her favorites: Sweet Potato Casserole with Marshmallows.

While we peeled sweet potatoes and measured brown sugar, she fondly recalled old times. “This dish,” she explained, stirring the pot with a wooden spoon, “represents more than a recipe. It’s a piece of our family history, a staple at our Thanksgiving table for generations.” Her words resonated with me, highlighting the recipe’s special place in our family.

Why do Americans put marshmallows on sweet potato casserole?

The tradition of adding marshmallows to sweet potato casserole originated from a marketing campaign by marshmallow companies in the early 20th century. Initially, sweet potatoes were often sweetened and served as a dessert. A recipe booklet published in 1917 included a recipe for mashed sweet potatoes with a marshmallow topping, which popularized this combination in American households. Over the years, it has become a beloved tradition, particularly for Thanksgiving meals.

How to Store Sweet Potato Casserole With Marshmallows

Storing Sweet Potato Casserole with Marshmallows correctly is essential to maintain its taste and texture, ensuring it remains just as delightful when you’re ready to enjoy it again. Here’s how you can store it effectively:

Cooling Down: Firstly, allow the casserole to cool to room temperature after baking. This prevents condensation inside the storage container, which could make the top layer soggy.

Choosing the Right Container: Transfer the casserole to an airtight container. If your baking dish comes with a lid, you can simply use that. Otherwise, transfer the casserole to a container that is large enough to hold it without squishing the marshmallow topping. Make sure the container seals tightly to keep out air and moisture.

Refrigeration: Once in the container, place the casserole in the refrigerator. It’s best consumed within 3-4 days. The cold environment helps to preserve the flavors and textures, although the marshmallows may soften slightly.

Freezing for Longer Storage: If you need to store the casserole for a more extended period, freezing is an option. Wrap the casserole dish tightly with aluminum foil or freezer wrap, or transfer it into a freezer-safe container. Sweet potato casserole can be frozen for up to 3 months. Note that while freezing can slightly alter the texture of the marshmallows, it still preserves the overall flavor of the dish.

Thawing and Reheating: When you’re ready to enjoy the casserole again, thaw it in the refrigerator if it was frozen. To reheat, place it in a 350°F oven until it’s heated through. If the marshmallows aren’t as crispy as you’d like, you can broil the casserole for a minute or two, but keep a close eye on it to prevent burning.

Microwaving Individual Portions: For a quick reheating of individual servings, the microwave works well. Heat in 30-second increments until the desired temperature is reached. The marshmallows might not be as crispy as when freshly baked, but the casserole will still be delicious.

How to Prepare Sweet Potato Casserole with Marshmallows


  • Sweet Potatoes: 5 medium-sized, peeled and cubed
  • Brown Sugar: 3/4 cup, light or dark based on preference
  • Margarine or Butter: 1/4 cup, softened
  • Orange Juice: 3 tablespoons, for a hint of citrus
  • Cinnamon: 1/2 teaspoon, for warmth
  • Miniature Marshmallows: 2 cups, for topping

Step by Step Directions

Preparing Sweet Potatoes: Peel and cube the sweet potatoes, then place them in a large pot. Cover them with water and bring to a boil over medium-high heat. After reaching a boil, reduce the heat to maintain a gentle boil. Cook the potatoes until they are tender, which should take about 15-20 minutes. Once tender, drain and return the sweet potatoes to the pot.

Mashing and Mixing: Mash the sweet potatoes until smooth, using a potato masher or an electric mixer. Then, add brown sugar, margarine, cinnamon, and orange juice to the mashed potatoes. Mix everything well to combine all the ingredients thoroughly.

Assembling the Casserole: First, preheat your oven to 350°F (175°C). Next, spread the sweet potato mixture evenly in a baking dish. Cover the top completely with miniature marshmallows.

Baking: Bake the casserole in the preheated oven for 25-30 minutes. The marshmallows should puff up and turn golden brown. Watch closely in the last few minutes to avoid burning the marshmallows.

Serving: After baking, remove the casserole from the oven. Let it cool slightly before serving. Enjoy this dish warm for the best experience, with the marshmallows soft and gooey

Frequently Asked Questions

Is sweet potato casserole runny before baking?

A runny sweet potato casserole before baking can be due to several factors, such as overcooked sweet potatoes, excess moisture, or insufficient baking time. To avoid this, ensure sweet potatoes are properly drained and not overcooked. The right balance of ingredients and adequate baking time are crucial for achieving the perfect consistency.

How do you thicken a sweet potato casserole?

If your sweet potato casserole is too runny, you can thicken it by adding more mashed sweet potatoes, using a thickening agent like cornstarch or flour, or baking it longer to allow excess liquid to evaporate. These methods can help achieve a creamier, more cohesive texture.

Can I use canned sweet potatoes?

Yes, you can use canned sweet potatoes in a pinch. Drain the canned yams thoroughly and proceed with the recipe as usual, keeping in mind that the flavor and texture may differ slightly from using fresh sweet potatoes.

Mini or large marshmallows in sweet potato casserole?

Mini marshmallows are recommended for sweet potato casserole. They provide a better ratio of gooey to crispy texture and are easier to eat. If only large marshmallows are available, they can be cut into smaller pieces for use.

Storage and reheating instructions?

Store leftover sweet potato casserole in the refrigerator for up to 4 days. Reheat in the microwave or oven until warmed through. Microwaving works well for small portions, while the oven is better for reheating larger quantities.

Is sweet potato casserole a dessert or a side dish?

Sweet potato casserole blurs the lines between dessert and side dish. Traditionally, especially in the Southern United States, it’s served as a side dish. However, given its sweet profile, topped with marshmallows, many also enjoy it as a dessert. The versatility of this dish allows it to fit seamlessly into either category, making it a unique addition to any meal.

What if I don’t like marshmallows?

If marshmallows aren’t to your liking or don’t fit your dietary needs, there are alternatives. You can top the casserole with a crumble made of nuts and spices, a coconut streusel, or simply enjoy it without any topping. These options provide a delightful crunch and an additional layer of flavor to the dish.

Is this recipe OK for my dairy-free diet?

Yes, this sweet potato casserole can be adapted for a dairy-free diet. Substitute the butter with a vegan alternative or olive oil. Also, if using marshmallows, ensure they are vegan-friendly, as some marshmallows contain gelatin, which is an animal-derived product.

Can I personalize this recipe with a twist?

Absolutely! Sweet potato casserole is a versatile recipe that welcomes personalization. Feel free to experiment by adding spices like nutmeg or allspice, substituting maple syrup for brown sugar, or even adding a splash of bourbon for an adult twist. If marshmallows aren’t your preference, try using crushed pineapple or a coconut streusel topping. These personal touches can make the dish uniquely yours while maintaining its classic charm.
