Essential Ingredients

Sweet Potatoes: Choose firm ones without blemishes for the best flavor. You can also use canned ones in a pinch.
Brown Sugar: Light or dark works wonderfully; it adds richness and enhances the natural sweetness.
Butter: Use unsalted butter to control the saltiness in your casserole; it makes everything richer.
Milk: Whole milk gives the best creaminess but feel free to swap with nut milk for dairy-free options.
Pecans: Preferably toasted; they add crunch and depth to balance the soft sweet potatoes.
Marshmallows: Miniature marshmallows are perfect for even melting; they create that dreamy topping we all love.

How to Make Sweet Potato Casserole with Marshmallows and Pecans
Prepare Your Sweet Potatoes: Start by preheating your oven to 400°F (200°C). Wash and peel about four medium-sized sweet potatoes, then chop them into cubes. Boil them in salted water until fork-tender, which takes about 15-20 minutes.
Mash Them Up!: Drain the sweet potatoes and return them to the pot. Add butter, brown sugar, milk, vanilla extract, a dash of salt, and cinnamon. Mash everything together until smooth and creamy—an arm workout you’ll thank me for later.
Add Some Crunch!: Fold in half of your chopped pecans gently into the mashed mixture. This adds texture while ensuring every bite has that nutty crunch you crave.
Transfer to Baking Dish: Pour your luscious mixture into a greased 9×13 inch baking dish. Spread it out evenly because no one likes an uneven casserole—it’s like wearing mismatched socks!
Topping Time!: Sprinkle mini marshmallows generously over the top along with the remaining pecans. The more marshmallows, the merrier! Trust me; this is where you want to go wild.
Bake Until Golden Brown: Place in your preheated oven for about 25-30 minutes or until those marshmallows are beautifully toasted and golden brown. Keep an eye on them; no one wants burnt marshmallow confetti!
And there you have it! A mouthwatering Sweet Potato Casserole with Marshmallows and Pecans that will have everyone asking for seconds…and maybe thirds!
