Let’s Make It Together
Preheat your oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with nonstick spray to prevent sticking.
Boil those sweet potatoes: Peel and chop about four large sweet potatoes into chunks. Boil them in salted water until fork-tender, which takes around 15-20 minutes.
Mash like you mean it: Drain the sweet potatoes and return them to the pot. Add butter and brown sugar before mashing until smooth. A hand mixer works wonders here if you’re feeling fancy.
Spice things up: Mix in cinnamon, vanilla extract, and a pinch of salt. Taste-test for sweetness—add more brown sugar if you’re feeling adventurous!
Spread it out: Pour this glorious mash into your greased baking dish, spreading it evenly with a spatula. Believe me when I say you’ll want every last bit!
Top it off: Sprinkle mini marshmallows generously over the top (and nuts if using). Bake in your preheated oven for about 25-30 minutes until golden brown and bubbly.
Serve and enjoy: Once baked, let it cool slightly before serving—this helps maintain shape! Watch as everyone digs in with glee—it’s bound to become a favorite!
Now that you’ve made this delectable sweet potato casserole, get ready for compliments from family and friends!
