Step-by-Step Instructions

1. Prepare the Sweet Potatoes

  • Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray.
  • Place the diced sweet potatoes in a large pot of salted water. Boil them for 15–20 minutes, or until fork-tender.
  • Drain the sweet potatoes and mash them until smooth.

2. Combine the Sweet Potato Base

  • In a large mixing bowl, combine the mashed sweet potatoes, brown sugar, toasted pecans, eggs, milk, melted butter, vanilla extract, cinnamon, nutmeg, and salt.
  • Mix until the ingredients are fully incorporated and creamy.
  • Spread the sweet potato mixture evenly into the prepared baking dish to create the base layer.

3. Prepare the Cinnamon Swirl

  • In a medium bowl, mix together softened butter, cinnamon, flour, and brown sugar.
  • Use your hands or a fork to combine the ingredients until a crumbly texture forms.
  • Sprinkle the cinnamon swirl evenly over the sweet potato layer in the baking dish.

4. Create the Pecan Topping

  • In a small bowl, mix the toasted pecans, flour, brown sugar, and melted butter until fully combined.
  • Spread the pecan mixture over the cinnamon swirl layer.

5. Add the Marshmallows and Bake

  • Evenly scatter the mini marshmallows over the top of the casserole.
  • Bake the casserole in the preheated oven for 25–30 minutes, or until the marshmallows are golden and bubbly.

6. Serve and Enjoy

  • Allow the casserole to cool slightly before serving. Serve warm and enjoy the compliments as your family and friends savor every bite!

Tips for Making the Best Sweet Potato Bake

  1. Toast the Pecans: Toasting enhances the flavor and adds a rich, nutty crunch. Simply bake the pecans in a 350°F (175°C) oven for 8–10 minutes or toast them in a dry skillet over medium heat.
  2. Make It Ahead: Prepare the sweet potato mixture and toppings a day in advance. Assemble the casserole just before baking to save time on busy holiday mornings.
  3. Adjust Sweetness: For a less sweet version, reduce the brown sugar in the sweet potato base or omit the marshmallows.
  4. Customize the Toppings: Not a fan of marshmallows? Use a streusel topping or add more pecans for extra crunch.
  5. Use Fresh Sweet Potatoes: While canned sweet potatoes work in a pinch, fresh ones deliver better flavor and texture.
