About the Ingredients
Sweet Potatoes
Mashed sweet potatoes create a naturally sweet, smooth base. Freshly baked or boiled sweet potatoes produce the best flavor, but canned sweet potato puree also works.
Granulated Sugar
Adds sweetness to balance the earthy flavor of the sweet potatoes.
Eggs
Provide structure and help the casserole set during baking.
Milk
Creates a creamy consistency that blends easily with the sweet potatoes.
Melted Butter
Adds richness to both the filling and the topping. Butter enhances the dish’s caramel-like flavor.
Vanilla Extract
Adds depth and warm aroma that complements the sweetness of the potatoes.
Salt
Balances the sweetness and enhances flavor.
Pecans
Provide crunch and nuttiness in the streusel topping. They toast beautifully as the casserole bakes.
Brown Sugar
Creates a caramelized, sweet crust on top.
Flour
Helps bind the streusel topping, giving it a classic crumb texture.
Tips & Tricks
Use Fresh Sweet Potatoes
Roasting sweet potatoes enhances their natural sweetness, making the casserole even more flavorful.
Mash While Warm
Mash the sweet potatoes while they’re warm to help create a smoother mixture that blends well with other ingredients.
Keep Streusel Crumbly
Avoid overmixing the streusel; keep it crumbly for the perfect texture that contrasts with the creamy filling.
Pro Tips
- Prepare the sweet potato layer a day ahead and refrigerate; add the streusel before baking.
- Let the casserole rest for 5–10 minutes after baking to help it set before serving.
- For extra creaminess, swap milk with half-and-half.
Step-by-Step Instructions
Preheat the Oven
Preheat your oven to 350°F (175°C) to ensure the casserole bakes evenly.
Mix the Sweet Potato Base
Combine mashed sweet potatoes, sugar, eggs, milk, 0.25 cup melted butter, vanilla, and salt in a bowl. Mix until smooth to create a creamy, flavorful base.
Prepare the Baking Dish
Spread the sweet potato mixture evenly into a greased 9×13-inch baking dish, ensuring an even layer for uniform baking.
Make the Streusel Topping
In a separate bowl, combine pecans, brown sugar, flour, and 0.25 cup melted butter until crumbly. This mixture creates a delightful crunchy topping.
Assemble and Bake
Sprinkle the streusel evenly over the sweet potato layer. Bake for 30 minutes or until the topping is golden brown and crisp, providing a beautiful contrast to the creamy filling.
Delicious Variations
Flavor Enhancements
Add a teaspoon of cinnamon or nutmeg to the sweet potato mixture for a warm, spicy note.
Topping Alternatives
