Equipment

  • Large mixing bowl
  • Potato masher or hand mixer
  • Measuring cups and spoons
  • Mixing spoon or spatula
  • Small bowl

Ingredients
  

Sweet Potato Base

  • 4 cups mashed sweet potatoes about 4–5 medium sweet potatoes
  • ½ cup granulated sugar
  • ½ cup brown sugar
  • ½ cup unsalted butter melted
  • ¼ cup milk
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • ½ teaspoon salt

Topping

  • ½ cup all-purpose flour
  • ½ cup brown sugar
  • ¼ cup unsalted butter melted
  • ½ cup chopped pecans optional, but so good!

Instructions
 

Prepare the Sweet Potatoes

  • Peel and chop 4–5 medium sweet potatoes into roughly 1-inch cubes.
  • Place them in a large pot and cover with water. Bring to a boil over medium-high heat.
  • Cook until tender, about 15–20 minutes. Test by piercing with a fork—if it slides in easily, they’re ready.
  • Drain the sweet potatoes well and return them to the pot.
  • Pro Tip: Let them sit in the pot for a minute after draining to let excess moisture evaporate—this keeps your casserole from getting watery.

Mash the Sweet Potatoes

  • Using a potato masher or hand mixer, mash the sweet potatoes until smooth.
  • Add ½ cup melted butter, ¼ cup milk, 2 large eggs, ½ cup granulated sugar, ½ cup brown sugar, 1 teaspoon vanilla extract, and ½ teaspoon salt.
  • Mix until fully combined and creamy. Taste and adjust sweetness if needed.
  • Pro Tip: Use a hand mixer on low speed to get a silky texture without overmixing, which can make the potatoes gummy.

Make the Topping

  • In a small bowl, combine ½ cup all-purpose flour, ½ cup brown sugar, and ¼ cup melted butter.
  • Stir until the mixture is crumbly and well blended.
  • If using pecans, fold in ½ cup chopped pecans for extra crunch and flavor.
  • Pro Tip: Toasting pecans lightly in a dry skillet before adding them to the topping enhances their nutty flavor.

Assemble the Casserole

  • Preheat your oven to 350°F (175°C).
  • Spread the mashed sweet potato mixture evenly in a 9x13-inch baking dish.
  • Sprinkle the topping evenly over the sweet potatoes.
  • Pro Tip: Pat the topping lightly so it sticks but still keeps its crumbly texture—this helps it bake evenly and get golden brown.

Bake Until Golden

  • Bake in the preheated oven for 25–30 minutes, or until the topping is golden and slightly crisp.
  • Remove from the oven and let it cool for a few minutes before serving.
  • Pro Tip: For extra crispiness, broil for 1–2 minutes at the end, keeping a close eye so it doesn’t burn.
