• Prep Time: 20 minutes
• Cook Time: 35 minutes
• Total Time: 55 minutes
• Servings: 8
• Yield: 1 (9×13-inch) casserole
• Dietary Type: Vegetarian

Ingredients

For the Sweet Potato Base:

• 6 cups mashed sweet potatoes, cooked and mashed (see note on cooking the sweet potatoes below)
• 1 cup sugar
• 1/2 teaspoon salt
• 1/4 cup melted butter or margarine
• 1 (14 ounce) can sweetened condensed milk
• 1/2 teaspoon vanilla
• 2 eggs, beaten

For the Topping:

• 1 cup brown sugar
• 1/4 cup flour
• 1 cup walnuts, chopped coarsely
• 1/4 cup melted butter or margarine

Equipment Needed

• Large pot
• Potato masher or electric mixer
• 9×13-inch baking pan
• Mixing bowls
• Measuring cups and spoons

Instructions

1. Preheat your oven to 350°F (175°C). Ensure your oven rack is positioned in the center for even baking.
2. Prepare the sweet potato mixture: In a large mixing bowl, combine the mashed sweet potatoes, sugar, salt, melted butter or margarine, sweetened condensed milk, vanilla, and beaten eggs. Mix until all ingredients are thoroughly combined and the mixture is smooth. An electric mixer can be used, but be careful not to overmix.
3. Pour the mixture into the prepared 9×13-inch baking pan, spreading it evenly across the bottom.
4. Make the topping: In a separate bowl, combine the brown sugar, flour, and chopped walnuts. Stir to combine.
5. Add the melted butter or margarine to the dry ingredients and mix well. Use a fork or your fingers to create a crumbly mixture. The mixture should be evenly moistened but not wet.
6. Sprinkle the topping evenly over the sweet potato mixture in the baking pan, ensuring it covers the entire surface.
7. Bake in the preheated oven for 35 minutes. The topping should be set, slightly melted into the sweet potatoes, and have a crispy, but flat top. To test for doneness, insert a toothpick into the center of the casserole. It should come out clean.
8. Remove from oven and let cool slightly before serving.

NOTE on cooking the sweet potatoes: To cook the sweet potatoes, fill a large pot with water and add the sweet potatoes. Bring the water to a boil over high heat. Once boiling, reduce the heat to medium-low, cover the pot with a lid, and let simmer for 30-35 minutes, or until the sweet potatoes are tender when pierced with a fork. Once cool enough to handle, peel the sweet potatoes and mash them thoroughly. You can also roast the sweet potatoes for a deeper flavor.

Expert Tips & Tricks

• Roast your sweet potatoes: Roasting the sweet potatoes instead of boiling them brings out a richer, caramelized flavor. Simply toss peeled and cubed sweet potatoes with olive oil, salt, and pepper, and roast at 400°F (200°C) until tender and slightly browned.
• Toast the walnuts: Toasting the walnuts before adding them to the topping enhances their nutty flavor and adds a delightful crunch. Spread the chopped walnuts on a baking sheet and bake at 350°F (175°C) for 5-7 minutes, or until fragrant. Watch them carefully to prevent burning.
• Make-Ahead Option: Prepare the casserole up to 24 hours in advance and store it, covered, in the refrigerator. Add the topping just before baking for the best texture.
• Prevent a Soggy Topping: If you’re concerned about a soggy topping, you can pre-bake the topping for a few minutes before adding it to the casserole. This will help it crisp up nicely in the oven.
• Spice it Up: Add a pinch of ground cinnamon, nutmeg, or ginger to the sweet potato mixture for a warmer, more aromatic flavor.

Serving & Storage Suggestions

Serve the sweet potato casserole warm as a side dish with your favorite holiday meals or as a decadent dessert. It pairs perfectly with roasted turkey, ham, or pork. For a more elegant presentation, garnish with a sprinkle of chopped pecans or a dollop of whipped cream.

Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. To reheat, bake in a preheated oven at 350°F (175°C) for 15-20 minutes, or until heated through. You can also reheat individual portions in the microwave.

For longer storage, the casserole can be frozen for up to 2-3 months. Thaw completely in the refrigerator before reheating.
