Sweet Potato Casserole with Marshmallows

Sweet potatoes are rich in vitamin A, dietary fiber, and many other substances. However, most people do not like the taste or texture and prefer to skip this source of vitamin A in favor of others. But, the only reason sweet potatoes are not tasty is that we don’t know how to prepare them.

Here’s one of many recipes for sweet potatoes that will make you consider buying them more often. And, if you already have some on your fridge, do not let them spoil, and try this recipe with us.

How to Make Sweet Potato Casserole with Marshmallows

This is a step-by-step recipe to make sweet potato casserole with marshmallows. You will see how easy it is, and the only time to prepare will be cooking time only because it has no complex preparation.

Once you have the ingredients listed at the bottom of this article, just follow the instructions, and you will have a sweet potato casserole ready in one hour tops:

Step 1: Peel the sweet potatoes

Peeling the sweet potatoes before boiling is the best idea, and you can do so with a knife. However, we recommend doing the task with a vegetable peeler. It won’t be time-consuming if you do it this way, and it is safer for your hands. Rinse your sweet potatoes after peeling and proceed to the next step.

Step 2: Cut them into large pieces

After peeling and rinsing, you can cut your sweet potatoes into large chunks. We want this step to reduce the boiling time by increasing the contact surface of the sweet potatoes to the boiling water. We don’t want tiny pieces because it could be difficult to drain the boiling water.

Step 3: Boil in water for 30 minutes

After that, boil the sweet potatoes using water in a pan. You can close the pan with a lid to make the boiling process faster, but I recommend taking off the cover after that to prevent any leaks.

Step 4: Cut the walnuts into pieces

As the sweet potatoes are boiling, you can use that time to cut the walnuts into smaller pieces. You can do it manually or with a mallet. Just ensure that the pieces are not very

Step 5: Mash the sweet potatoes

After 30 minutes, we recommend testing the softness of the sweet potatoes before taking them out. When they are soft, take a fork and mash them into a paste.

Step 6: Add butter and mix

In mashing the sweet potatoes, you may need some extra help, and butter can do the trick. Adding 3 tablespoons of butter makes it easier and softer to mash. You could also add some water if you didn’t achieve a paste-like texture.

Step 7: Add salt, cinnamon, brown sugar, and vanilla

When your mix looks like a paste, add 1 tablespoon of salt, 1 tablespoon of cinnamon, and ½ cup of brown sugar. Mix everything thoroughly and continue to the next step.

Step 8: Add the walnuts to the mix

After your mixture looks homogeneous, it is time to add the walnuts and mix once again. Remember, they are not small pieces, and you will no longer see a homogeneous mix, which is fine.

Step 9: Add the marshmallows on top

When you’re done mixing the ingredients above, it is time to put marshmallows above until they cover the mix. Were you mixing the ingredients in a separate bowl, take it to a baking tray before adding the marshmallows.

Step 10: Bake for 25 minutes

This preparation goes straight to the oven at a temperature of 375ºF. Leave it there for 25 minutes, and you will be ready to go.

Step 11: Enjoy

Serve your sweet potato casserole with marshmallows and share it with your guests.

Ingredients for Sweet Potato Casserole

As you can see, the main ingredients of a sweet potato casserole are:

• Sweet potatoes: They are the base of everything, and no change can be made here.
• Butter: It will give a softer texture to the mix and the casserole once finished. You can replace regular butter with vegan and non-dairy options if you like. It won’t have the same texture, but it will equally taste amazing.
• Sugar: We recommend brown sugar, but you can use any other type for this sweet potato casserole recipe. You could replace brown sugar with stevia or Splenda to make it healthier.
• Salt: The combination of salt and sugar will make other flavors stand out. If you consider the proportion, this recipe is mostly sweet with a pinch of salt.
• Vanilla and cinnamon: They are here to provide a particular flavor to your potato casserole. If you like to play with flavors and spices, you can add others to your mix.
• Walnuts: We also recommend walnuts because they give a crunchy feel to the recipe. They are also an excellent source of healthy fatty acids.
• Other ingredients: We recommended marshmallows as an additional ingredient to put on top. You can alternatively cover the casserole with red fruits and streusel, which is easy to prepare using flour, butter, cinnamon, and sugar. You could also find eggs and milk in other recipes, which will give a firm texture to the casserole after baking. But it all depends on your preferences and what works best for you.

One of the most common questions people ask is how to reduce the calorie count in this recipe. Sweet potatoes may have a high-calorie count, but their glycemic index is low. It has dietary fiber and won’t cause dramatic glucose spikes. To make your recipe healthier, you need to take out the marshmallows and replace sugar with other sweeteners.

Here’s a useful table to show you what proportion to use in each case:

Sugar measure	Sugar alternatives
½ cup of brown sugar	½ cup of white or refined sugar
½ cup of brown sugar	12 Stevia packets or 1 tablespoon of Stevia powder
½ cup of brown sugar	1 tablespoon of liquid Stevia (SweetLeaf)
½ cup of brown sugar	½ cup of honey
½ cup of brown sugar	3 ½ tablespoons of Truvia Spoonable

Can You Make Sweet Potato Casserole in Advance?

Of course! It is possible to prepare sweet potato casserole in advance. It is a good idea if you’re preparing for a special date such as Thanksgiving and want to take care of other dishes, decorations, and hundreds of extra details. Being a host can be demanding, but you can prepare this recipe ahead of time if you’re foreseeing stressful days ahead.

Saving your sweet potato casserole for later will not affect the taste. Many of us agree that the consistency and flavor improve if you keep it from later instead of serving it straight from the oven.

You can save this casserole for later today or take it out one or two days after preparing it. Either way, it will taste amazing. Just make sure that you’re refrigerating your sweet potato casserole with marshmallows.

The instructions are the same, but this time the marshmallows are a must. Another option would be creating a streusel with nuts and seeds, which will do the same on top and increase the shelf life.

The only extra instruction is this:

Do not place the sweet potato mixture right into the refrigerator after taking it out from the oven. Wait for the ingredients and the mix to cool down. This will allow the spices and flavors to settle in and combine. I would say 30 minutes to 1 hour at room temperature is enough before placing the baking tray into the fridge. Do not leave it for 2 hours or more because it grows bacteria after this time. We may also recommend taking the casserole to another dish if you prefer.

Another option to prepare sweet potato casserole in advance:

Prepare the mixture and reach step 8 of this recipe. Save the sweet potato casserole mix into the fridge for one day or two. When you’re ready to serve, place the marshmallows on top and bake for 25 minutes at 375ºF.

Storage and Reheating Instructions

You can store a tray of potato casserole with marshmallows in the fridge, and it will stay for several days without a problem. You just need to make sure that you’re covering your casserole well enough to prevent dehydration, which often happens in the fridge. After storing, you can reheat your casserole or the leftovers when you’re ready to eat it.

If you’re done eating or have decided to bake and store this sweet potato casserole recipe, the first thing you need to do is allow it to cool down, as noted above. After cooling down at room temperature for up to 1 hour, place it on a sealing container or cover the container with plastic wrap and aluminum foil on top. You can store the casserole in the baking tray or another oven-safe compartment. That way, reheating will be easier because you won’t need to move it elsewhere.

Reheating does not require thawing it out before, but you can do sp if you prefer. If you want a faster reheating time, you can take it straight to the oven for 20 minutes or until you feel it reaches the right temperature. Another option would be using the microwave, but make sure that it is properly done because microwaves are known to reheat parts of the dish while leaving others freezing cold.
