How to Make Cheesy Mashed Sweet Potato Casserole
Boil the Potatoes: Fill a pot with water and bring it to a rolling boil. Add the chopped sweet potatoes and cook for 10 to 15 minutes until they are tender and easily pierced with a fork. Drain and return them to the pot.
Mash Until Creamy: Add the melted butter, Greek yogurt, garlic powder, and sea salt to the potatoes. Mash everything together until it s smooth and creamy. Give it a taste and adjust the salt if needed!
Preheat the Oven: While you re mashing, preheat your oven to 375 °F (190 °C). This will ensure your casserole bakes perfectly.
Prepare the Casserole Dish: Spoon the mashed sweet potatoes into a 13 x 9 casserole dish, spreading them out in an even layer to create a solid base for your cheesy topping.
Add the Cheese and Bake: Generously sprinkle the grated cheese over the mashed sweet potatoes. Place the casserole in the oven for 20 to 25 minutes, or until the cheese is bubbly and golden on top.
Cook the Bacon: As the casserole bakes, heat a skillet over medium-high heat. Cook the chopped bacon, stirring occasionally, until it s crispy and perfectly browned.
Garnish and Serve: Once the casserole is out of the oven, top it with the crispy bacon bits and chopped green onion for that extra flavor and crunch.
Enjoy Together: Serve the cheesy mashed sweet potato casserole alongside your favorite main dish, and watch everyone reach for seconds!
