Step-by-Step Instructions for Thanksgiving Sweet Potato Soufflé
Step 1: Prepare the Sweet Potatoes
Preheat your oven to 400°F (205°C). Wash sweet potatoes thoroughly and pierce several times with a fork. Place directly on the oven rack and bake for 45-55 minutes until completely tender when pierced with a knife. The caramelization that happens during this process develops deeper flavor than boiling or steaming.
Step 2: Reduce Heat and Prepare Baking Dish
Once the sweet potatoes are done, reduce oven temperature to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray. For extra flavor, rub the inside of your baking dish with a cut garlic clove before greasing.
Step 3: Create the Sweet Potato Base
When cool enough to handle, peel sweet potatoes and place the flesh in a large mixing bowl. Add softened butter and sugar, then beat with an electric mixer until smooth and fluffy. For the silkiest texture, use a stand mixer with the paddle attachment at medium speed for 2-3 minutes.
Step 4: Incorporate Remaining Base Ingredients
Beat in eggs one at a time, then add vanilla extract, milk, cinnamon, nutmeg, and salt. Continue mixing until completely incorporated and no streaks remain. The mixture should have a smooth, pourable consistency that coats the back of a spoon.
Step 5: Prepare the Pecan Topping
In a separate bowl, combine brown sugar, flour, chopped pecans, melted butter, and cinnamon. Mix until the ingredients are evenly moistened and form a crumbly texture. For extra richness, toast the pecans at 350°F for 8 minutes before adding them to the topping mixture.
Step 6: Assemble and Bake
Pour the sweet potato mixture into the prepared baking dish, smoothing the top with a spatula. Sprinkle the pecan topping evenly over the surface. Bake at 350°F for 30-35 minutes until the center is just set and the topping is golden brown and fragrant.

Common Mistakes to Avoid for Thanksgiving Sweet Potato Soufflé
- Using cold ingredients: Room temperature eggs and butter incorporate more air, creating a lighter texture
- Overbeating after adding eggs: This causes density—mix just until combined
- Under-baking: The center should be just set; according to culinary institute testing, internal temperature should reach 165°F
- Using old spices: Cinnamon loses 80% of its flavor after 6 months, so fresh spices make a noticeable difference
- Skipping the rest period: Letting the soufflé rest for 5-10 minutes after baking allows it to set properly for easier serving

- Refrigerate leftovers within two hours of serving in an airtight container for up to 4 days

- When ready to serve, allow to come to room temperature for 30 minutes before baking as directed

FAQs for Thanksgiving Sweet Potato Soufflé
Can I make this soufflé without eggs?
Yes! Substitute each egg with ¼ cup of mashed silken tofu or a commercial egg replacer. The texture will be slightly different but still delicious.
What’s the difference between sweet potato soufflé and sweet potato casserole?
While often used interchangeably, a proper soufflé incorporates whipped eggs for a lighter, more aerated texture, whereas casseroles tend to be denser and often contain less dairy.
Can this dish be made in a slow cooker?
Absolutely! Cook on low for 3-4 hours. The topping won’t get quite as crisp, but you’ll free up valuable oven space during holiday cooking.
Why are my sweet potatoes stringy?
Stringiness usually indicates underripe potatoes. Select medium-sized sweet potatoes with smooth, unblemished skin for the best texture.
Can this be adapted to a vegan diet?
Yes! Use plant-based butter, plant milk, and replace eggs with a mixture of 2 tablespoons ground flaxseed mixed with 6 tablespoons water (let sit for 10 minutes before using).
