  • Brown Sugar: This adds a rich sweetness. You can use light or dark brown sugar, depending on your preference.
  • Butter: A must for that luscious texture. I prefer unsalted, but feel free to use salted if that’s what you have on hand.
  • Shamrock Farms Heavy Whipping Cream: This gives the casserole its creamy consistency. You can substitute with half-and-half or even coconut cream for a dairy-free option.
  • Salt: Just a pinch enhances all the flavors. Don’t skip it!
  • Vanilla Extract: This adds a warm, inviting aroma. Pure vanilla is best, but imitation works in a pinch.
  • Cinnamon: A classic spice that brings warmth and depth to the dish.
  • Pumpkin Pie Spice: This is optional but adds a lovely fall flavor. Ground nutmeg can be a great substitute.
  • All-Purpose Flour: This helps create a crumbly topping. If you’re gluten-free, almond flour or a gluten-free blend can work.
  • Rolled Oats: They add texture to the topping. Quick oats can be used if that’s what you have.
  • Mini Marshmallows: The star of the show! They melt beautifully and create that gooey topping we all crave.

How to Make Sweet Potato Casserole With Marshmallows

Now that we have our ingredients ready, let’s dive into the fun part: making this Sweet Potato Casserole With Marshmallows! Follow these simple steps, and you’ll have a delicious dish that will wow your family and friends.

Preparing the Sweet Potatoes

First, we need to get those sweet potatoes ready. You can choose to boil or bake them, depending on your preference.

If boiling, wash, peel, and cube the sweet potatoes into pieces about 1 inch or smaller. Place them in a large pot and cover with water. Bring it to a rolling boil. Once they’re easily pierced with a fork, drain and return them to the pot.

If you prefer baking, preheat your oven to 425°F. Wash and dry the sweet potatoes, then pierce each one with a knife 3-4 times. Bake for 50-70 minutes until they’re soft. Once done, remove the skins and place the sweet potatoes in a large bowl.

Mixing the Ingredients

Next, let’s create that creamy filling! Preheat your oven to 375°F if you haven’t already.

Add the brown sugar, butter, Shamrock Farms Heavy Whipping Cream, salt, vanilla extract, cinnamon, and pumpkin pie spice to the cooked sweet potatoes. Mash everything together until it’s smooth and creamy. The aroma will be heavenly!

Spoon the mixture into a lightly sprayed 9×13 baking pan, smoothing it out evenly. This is where the magic begins!

Baking the Casserole

Now, let’s prepare the topping. In a separate bowl, combine the flour, brown sugar, rolled oats, and cinnamon. Stir until well mixed.

Pour in the melted butter and mix until you achieve a crumb-like texture. Sprinkle this mixture over the sweet potato layer in the baking pan.

Bake the casserole for about 20 minutes. You want it to be warm and slightly set before we add the marshmallows.

Adding the Marshmallows

Here comes the best part! Carefully sprinkle the mini marshmallows over the topping. Return the casserole to the oven for another 10-15 minutes. Keep an eye on it until the marshmallows start to brown and get that gooey, toasted look.

Once done, remove it from the oven and let it cool for a few minutes. Then, serve it warm and watch everyone’s faces light up with joy!

Tips for Success

  • Choose sweet potatoes that are firm and free of blemishes for the best flavor.
  • For a smoother texture, use a potato masher or electric mixer when mashing.
  • Don’t skip the resting time after baking; it helps the flavors meld together.
  • Feel free to adjust the sweetness by reducing the brown sugar if desired.
  • Experiment with toppings like pecans or coconut for a unique twist!

Equipment Needed

  • Large Pot: For boiling sweet potatoes. A Dutch oven works well too.
  • Baking Pan: A 9×13 inch pan is ideal. You can use any similar-sized dish.
  • Mixing Bowls: A couple of medium-sized bowls for mixing ingredients.
  • Potato Masher: For mashing sweet potatoes. An electric mixer can save time.
  • Measuring Cups and Spoons: Essential for accurate ingredient measurements.

Variations of Sweet Potato Casserole With Marshmallows

  • Nutty Delight: Add chopped pecans or walnuts to the topping for a crunchy texture and nutty flavor.
  • Maple Twist: Substitute brown sugar with pure maple syrup for a unique sweetness that pairs beautifully with sweet potatoes.
  • Dairy-Free Option: Use coconut cream instead of heavy whipping cream and dairy-free butter for a delicious vegan version.
  • Spiced Up: Incorporate a pinch of cayenne pepper or chili powder for a surprising kick that balances the sweetness.
  • Fruit Fusion: Mix in some diced apples or pears for added sweetness and a fruity twist that complements the dish.
