About This Recipe
When the holidays roll around, there's no better dessert to make than this sweet potato casserole. It's a recipe I make every year, not only because it's delicious, but because everyone always requests it! This recipe and my stuffing are always the biggest hits.
There is always a debate about whether marshmallows belong on a sweet potato casserole. My answer is yes! The marshmallows taste so delicious on top. They get melty on the inside, but they also get crispy and golden. It adds such a cozy element, like you're eating at the campfire.
P.S. I love making a bit extra of the pecan streusel and serving it on the side. I cook it in the air-fryer for about 5 minutes, and it gets perfectly toasted.
Key Ingredients
Marshmallows: This is my favorite part! I can never resist sneaking a few marshmallows right after they're done baking. This is called the chef's tax.
Sweet Potatoes: You'll need about 3 pounds of sweet potatoes; about 4 large sweet potatoes.
Brown Sugar: I love brown sugar in this recipe. The molasses flavor complements the sweet potatoes very well.
Butter: Make sure the butter is melted so that it mixes easily into the mashed sweet potatoes without needing to overmix.
Vanilla Extract: One teaspoon of vanilla extract really makes the flavors pop.
Cinnamon & nutmeg: For the cozy fall flavor.
Flour: For the streusel.
Pecans: You can also use walnuts. Make sure they are raw and not already roasted.
Instructions
STEP 1: In a large pot, add the sweet potatoes and cover with water. Bring to a boil and simmer for 15 minutes until fork-tender. Drain.
STEP 2: In a large bowl, mash the sweet potatoes with brown sugar, butter, vanilla, cinnamon, and nutmeg.
STEP 3: Spread into the baking dish.
STEP 4: In a separate bowl, combine all the pecan topping ingredients and mix until combined. Sprinkle on top of the sweet potatoes, followed by the marshmallows
STEP 5: Bake for 25-30 minutes until the marshmallows are golden brown on top.
