Tasty Sweet Potato Casserole with Brown Sugar Topping

Here is my favorite sweet potato casserole recipe, with creamy mashed sweet potatoes, warm spices, and a crunchy brown sugar topping that gets golden and caramelized in the oven.

This sweet potato casserole is always the first dish to disappear at our Thanksgiving table. I’ve been making it for years, and my kids always ask for seconds before they even finish their turkey. It’s the perfect balance of sweet and comfort that makes everyone happy.

What Kind of Sweet Potatoes Should I Use?

You can absolutely use canned sweet potatoes for this casserole, which is what makes this recipe so convenient and quick to prepare. If you prefer to use fresh sweet potatoes, go for the orange-fleshed varieties like Beauregard or Centennial since they’re naturally sweeter and have that classic creamy texture we all love in casseroles. When using fresh, you’ll want to bake or boil them until they’re fork-tender, then peel and mash them up. Whether you choose canned or fresh, make sure to drain any excess liquid well so your casserole doesn’t turn out watery.

Options for Substitutions

This classic sweet potato casserole is pretty forgiving when it comes to swaps:

• Canned sweet potatoes: Fresh sweet potatoes work great too! You’ll need about 2-3 pounds. Just bake them at 400°F until tender, then peel and mash. The texture will be slightly different but equally tasty.
• Butter: You can substitute with coconut oil (use the same amount) or vegetable oil, though you’ll lose some of that rich buttery flavor.
• Milk: Heavy cream makes it richer, while almond milk or oat milk work for dairy-free versions. You might need to adjust the amount slightly depending on your sweet potato consistency.
• Pecans: Walnuts or chopped almonds make good substitutes. If you’re dealing with nut allergies, try toasted pumpkin seeds or just skip the nuts altogether for a simple brown sugar crumble.
• Brown sugar: White sugar mixed with a tablespoon of molasses works in a pinch, or you can use coconut sugar for a slightly different flavor profile.
• Eggs: For each egg, you can substitute with 1/4 cup applesauce or 1 tablespoon ground flaxseed mixed with 3 tablespoons water (let it sit for 5 minutes first).

Watch Out for These Mistakes While Baking

The biggest mistake people make with sweet potato casserole is not draining the canned sweet potatoes well enough, which creates a watery base that won’t set properly – pat them dry with paper towels and let them sit for a few minutes before mashing.

Another common error is overmixing the sweet potato base, which can make it gluey instead of creamy, so mix just until the ingredients are combined and the texture is smooth.

For the brown sugar topping, make sure your butter is melted but not hot when you mix it with the flour and brown sugar – hot butter will create clumps instead of the crumbly texture you want.

Finally, don’t skip letting the casserole rest for 10 minutes after baking, as this helps the custard-like base firm up and makes serving much cleaner.

What to Serve With Sweet Potato Casserole?

Sweet potato casserole is a holiday table staple that pairs beautifully with classic Thanksgiving and Christmas dishes. I love serving it alongside roasted turkey or glazed ham, where the sweet and savory flavors really complement each other. Green bean casserole, stuffing, and cranberry sauce make perfect side dish companions, creating that traditional holiday spread everyone looks forward to. For a more casual meal, this casserole also works great with roasted chicken or pork tenderloin, and don’t forget some dinner rolls to round out the plate!

Storage Instructions

Refrigerate: Sweet potato casserole keeps really well in the fridge! Cover it tightly with foil or plastic wrap and it’ll stay fresh for up to 4 days. I actually think it tastes even better the next day when all those flavors have had time to meld together.

Freeze: This casserole is perfect for making ahead of the holidays. You can freeze it either before or after baking for up to 3 months. If freezing unbaked, just thaw it overnight in the fridge before popping it in the oven. Already baked? Thaw and reheat when you’re ready to serve.

Warm Up: To bring your casserole back to life, cover it with foil and bake at 350°F for about 15-20 minutes until heated through. If the topping needs a little crispiness back, remove the foil for the last 5 minutes. You can also microwave individual portions, though the topping won’t be as crunchy.

Ingredients

For the sweet potato filling:

• 1/2 cup butter, melted
• 2 eggs, beaten
• 1/3 cup milk (whole milk is recommended for a creamier texture)
• 1 tsp vanilla extract
• Salt, to taste
• 3/4 cup cane sugar
• 3 cups sweet potatoes (I use Libby’s pumpkin puree for this, it’s easier and tastes the same)

For the pecan topping:

• 2/3 cup light brown sugar (packed well for accurate measurement)
• 1 cup chopped pecans (finely chopped for better distribution)
• 2/3 cup all-purpose flour
• 5 tbsp butter, melted

Step 1: Prepare the Sweet Potato Filling

• 3 cups sweet potatoes, drained (from a 29 oz can)
• 1/2 cup butter, melted
• 1/3 cup milk
• 3/4 cup cane sugar
• 1 tsp vanilla extract
• 2 eggs, beaten
• salt, to taste

Preheat your oven to 350°F (175°C).

In a large mixing bowl, mash the drained sweet potatoes until smooth.

Add 1/2 cup melted butter, milk, cane sugar, vanilla extract, beaten eggs, and a pinch of salt to the mashed sweet potatoes.

Stir until everything is thoroughly incorporated.

Pour the sweet potato mixture into a shallow baking dish or a cast iron skillet, spreading it evenly.

Step 2: Make and Add the Pecan Crumble Topping

• 5 tbsp butter, melted
• 2/3 cup light brown sugar
• 2/3 cup all-purpose flour
• 1 cup chopped pecans

In a small bowl, combine the remaining 5 tablespoons melted butter with the light brown sugar, flour, and chopped pecans.

Use your fingers to mix everything together until a moist, crumbly texture forms.

Gently sprinkle this pecan crumble topping evenly over the sweet potato mixture in the baking dish.

I like to slightly press the topping into the filling so it sticks nicely while baking.

Step 3: Bake and Serve the Casserole

Place the baking dish in the preheated oven and bake for 25-35 minutes, or until the edges pull away from the sides of the pan and the top is golden brown.

Remove from the oven and let the casserole stand for a few minutes to cool slightly and allow it to firm up before serving.

This little rest makes it easier to scoop and keeps the topping crisp.
