Step-by-Step Instructions for Sweet Potato Casserole with Pecans

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray.

Step 2: Cook and Mash Sweet Potatoes

Peel and cube the sweet potatoes. Boil them in a large pot of water until fork-tender, about 15–20 minutes. Drain, then mash until smooth. You should have about 4 cups of mashed sweet potato.

Step 3: Mix the Filling

In a large mixing bowl, combine the mashed sweet potatoes, brown sugar, eggs, melted butter, milk, vanilla, salt, and cinnamon. Stir until smooth and creamy.

Step 4: Spread Into Baking Dish

Transfer the sweet potato mixture into the prepared baking dish, spreading it evenly.

Step 5: Make the Pecan Topping

In a separate bowl, mix flour, brown sugar, melted butter, chopped pecans, and a pinch of salt until crumbly. Sprinkle evenly over the sweet potato mixture.

Step 6: Bake

Bake for 35–40 minutes, or until the top is golden and the casserole is set. Let it cool slightly before serving.

Choosing the Best Sweet Potatoes

Fresh vs. Canned

Fresh sweet potatoes offer superior flavor and texture. Canned can be used in a pinch, but make sure they’re drained and not packed in syrup.

Types of Sweet Potatoes

Look for orange-fleshed varieties like Beauregard or Jewel. These are naturally sweeter and creamier.

Pecans: Raw, Roasted, or Toasted?

Use raw pecans when mixing with sugar and butter—they’ll toast while baking. For extra crunch and flavor, you can lightly toast the pecans in a skillet before adding them to the topping mixture.

Optional Add-Ins for the Filling

Want to add a twist? These mix-ins complement sweet potatoes beautifully:

  • Crushed pineapple (for brightness and acidity)

  • Maple syrup (swap for part of the brown sugar)

  • Orange zest (adds freshness)

  • Nutmeg or allspice (for a spicier aroma)

  • Cream cheese (adds extra richness)

Marshmallow vs. Pecan Topping Debate

This dish often sparks debate: marshmallows or pecans?

  • Pecan Topping: Crunchy, nutty, and less sweet—adds contrast and texture.

  • Marshmallow Topping: Sweet, gooey, and nostalgic—perfect for dessert lovers.

Best of Both? Add marshmallows for the final 10 minutes of baking on top of the pecans for a layered effect!

How to Make It Ahead

You can easily prepare this dish ahead of time:

  • Unbaked Version: Assemble the casserole (without the pecan topping), cover, and refrigerate for up to 2 days. Add the topping right before baking.

  • Fully Baked Version: Bake, cool, then refrigerate. Reheat at 350°F for 20–25 minutes covered with foil.

How to Store and Reheat

Storage:

  • Cool completely before storing.

  • Keep in an airtight container in the fridge for up to 4–5 days.

Reheating:

  • Oven: Cover with foil and reheat at 350°F until warm (15–20 minutes).

  • Microwave: Heat individual portions for 1–2 minutes until heated through.

Can You Freeze Sweet Potato Casserole?

Yes! Here’s how:

  • Unbaked Freezing: Prepare the filling, freeze it in the baking dish (without the topping). When ready to serve, thaw overnight, add the topping, and bake fresh.

  • Baked Freezing: Let it cool completely. Wrap tightly and freeze for up to 2 months. Reheat from frozen, covered with foil, at 350°F until warmed through.
