Sweet Potato Soufflé (Holiday Sweet Potato Casserole Recipe)

You’ve probably seen it called a sweet potato casserole, or maybe a soufflé with a crunchy pecan topping. Either way, this Sweet Potato Soufflé is one of those holiday side dishes that feels special but is totally doable. It’s been requested for years by friends and family, and now it’s a regular in many kitchens.

This recipe, shared with love by Ashley, has the perfect balance of creamy sweet potatoes, buttery topping, and just the right touch of sweetness. I want you to feel confident making it, whether it’s for a holiday feast or a Sunday dinner with loved ones.

Why This Sweet Potato Soufflé Works

• Familiar ingredients you likely already have: sweet potatoes, butter, sugar, eggs, vanilla, pecans, etc.
  
• No tricky techniques. If you can mash potatoes and mix a crumble topping, you’re golden.
  
• It hits that sweet-savory spot that keeps people coming back for seconds.
  
• It’s a standout side dish that elevates any meal without requiring meat or hours in the kitchen.

Ingredients You’ll Need

Here’s what goes into the soufflé itself and the topping:

For the Sweet Potato Base:

• 3–4 large sweet potatoes
  
• 2 eggs
  
• 1 cup granulated sugar
  
• 1 stick (½ cup) butter
  
• 1 teaspoon vanilla extract
  

For the Topping:

• 1 cup brown sugar
  
• ⅓ cup softened butter
  
• ⅓ cup all-purpose flour
  
• 1 cup chopped pecans
  

Depending on your crowd, you may want to scale up or down. This recipe fits nicely into an 8×8 baking dish.  If you need to use another size, just adjust the baking time slightly.

Instructions

1. Boil the Sweet Potatoes

Wash, cut into chunks, and boil them (with skin on) until fork-tender. Afterward, it’s easy to slip the skins off.

2. Preheat Oven to 350°F

3. Make the Base

In a large bowl, cream together the cooked sweet potatoes, eggs, sugar, butter, and vanilla until smooth and creamy.

4. Pour into the Baking Dish

Transfer that sweet potato mixture into your casserole dish (8×8 is a good size).

5. Make the Topping

In a separate bowl, mix brown sugar, softened butter, flour, and pecans until you get a crumbly consistency.

6. Top and Bake

Sprinkle the topping over the sweet potato base. Bake for about 30 minutes, or until the top is golden and the filling is set (but still moist).

7. Serve Warm

Let it cool just enough to slice portions cleanly, and serve warm for the best flavor and texture.

Frequently Asked Questions (FAQ)

Can I use canned sweet potatoes instead of fresh?
You can, but fresh gives you better texture and flavor. If using canned, drain well and maybe reduce added butter or sugar slightly because canned versions can be sweeter.

How many servings does this recipe make?
In an 8×8 dish, this recipe serves about 6 to 8, depending on portion size.

Why boil with the skins on?
Boiling with skins on helps prevent loss of moisture. After boiling, the skins slip off easily. It’s easier than peeling and less messy. 

Can I prepare this the night before?
Yes! Assemble everything (base + topping) and store covered in the fridge. Before baking, let it sit closer to room temperature, and bake it a little longer (about 5–10 extra minutes) so it heats through.

How do I reheat leftovers?
Reheat in the oven at 325°F for 10–15 minutes until warm, or microwave individual portions. The topping might soften a bit, but the flavors will still shine.Is this more of a soufflé or a casserole?
It blends elements of both. Because it’s baked with a crumble topping, many call it a casserole. But its creamy, airy nature gives it a soufflé-like quality. Either way, it’s delicious.

Serving Suggestions & Pairings

Here are a few ideas to pair with the sweet potato soufflé:

• Serve alongside turkey, ham, or roast meats at holiday meals
  
• Add it to a dinner where you want a sweet side instead of a plain one
  
• Use it at brunch with eggs and sausage
  
• Offer it as a dessert side. It’s sweet enough that some folks eat it in place of dessert.  Try serving it with whipped topping or vanilla ice cream.
