Cooking Steps
Preheat your oven to 350°F.
Then, peel and dice those sweet potatoes before boiling them until they're nice and tender.
Step 1. Preheat Oven to 350°F

To get started, you'll want to preheat your oven to 350°F. This is an important first step in making your delicious sweet potato casserole.
As the oven heats up, you can start preparing the other ingredients.
Once that oven is nice and toasty, you'll be ready to pop your casserole dish right in. The even heat will help your sweet potatoes get soft and creamy, while also giving the marshmallows a lovely golden-brown color on top. Mmm, can't you just imagine the aroma wafting through your kitchen?
Be sure to set a timer, so you don't forget about it. You'll want to bake the casserole for about 25-30 minutes, until everything is heated through and the marshmallows are perfectly puffed up.
Then, you can call your family to the table for a tasty and comforting side dish that's sure to satisfy everyone's sweet tooth.
Step 2. Peel and Dice Sweet Potatoes

Grab a sharp knife and peel the sweet potatoes. Slice off both ends, then run the knife along the sides to remove the skin.
Once they're peeled, place the sweet potatoes on a cutting board. Carefully slice them into 1-inch cubes, making sure to keep your fingers tucked safely away from the blade. The sweet potato's vibrant orange flesh is going to look so appetizing once it's all diced up!
Now, gather up those bite-sized pieces and transfer them to a large baking dish. You want to make sure the sweet potatoes are in a single layer, not piled on top of each other. This will help them cook evenly.
Can you already smell that sweet, cinnamon-y aroma filling the kitchen? It's going to be heavenly!
With the sweet potatoes prepped, you're one step closer to enjoying a cozy, comforting casserole. Keep up the great work – the best is yet to come!
Step 3. Boil Sweet Potatoes Until Tender

With the sweet potatoes neatly diced and ready to go, it's time to get them cooking.
You'll want to grab a large pot and fill it up with water, making sure there's enough to cover the potatoes. Once that's done, pop that pot on the stove and crank up the heat to high.
As the water starts to bubble and boil, carefully add the diced sweet potatoes. Let them cook for about 15-20 minutes, or until they're nice and tender when you poke them with a fork.
Don't be afraid to give them a stir every now and then to make sure they're cooking evenly. Once they're at that perfect soft and tender stage, it's time to drain the water and get ready for the next step.
The sweet potatoes are looking amazing and ready to be transformed into an irresistible casserole. Get excited, because the fun is just beginning!
Step 4. Mash Boiled Sweet Potatoes

Once the sweet potatoes have finished cooking, it's time to mash them up! Grab a large bowl and a potato masher.
Carefully scoop the soft, tender sweet potatoes out of the pot and into the bowl. Now, start mashing them up with the potato masher. Press down and twist the masher, smashing the sweet potatoes into a smooth, creamy texture.
As you mash, you'll notice the sweet aroma of the potatoes filling the air. Keep going until there are no more lumps or chunks – just a lovely, velvety mash. Once you’ve achieved that perfect consistency, add in some butter, a splash of cream, and a generous sprinkle of salt and pepper. These additions will elevate your mashed potatoes into a creamy potato recipe that will have everyone coming back for seconds. Serve it alongside your favorite protein and some steamed veggies for a comforting and satisfying meal.
Once they're all mashed up, give them a quick stir to ensure everything is evenly combined. Now your sweet potatoes are ready for the next step in making that delicious sweet potato casserole!
Get ready to mix in the rest of the ingredients and bake this tasty dish to perfection.
Step 5. Add Marshmallows on Top

After mashing the sweet potatoes, it's time to add the crowning touch – a layer of fluffy marshmallows. These pillowy soft puffs will create a delightful contrast to the rich, creamy sweet potato base.
Simply spread a generous layer of marshmallows evenly over the top of the mashed sweet potatoes. You'll want to make sure every inch is covered, so the sweet potatoes are completely hidden beneath the pillowy white topping.
Now, pop the casserole dish into the oven and let the magic happen. As it bakes, the marshmallows will start to puff up and turn a beautiful golden brown. The heat will melt them just enough to create a gooey, sticky topping that'll have everyone's mouth watering.
When it's done, the marshmallows should be lightly charred on top, adding a hint of caramelized sweetness. Get ready for oohs and aahs when you bring this irresistible dish to the table!
