- Maple Syrup: ⅓ cup (adjust to taste).

How to Make It (Step-by-Step)
Follow these simple steps to get the perfect creamy-crunchy balance.
Step 1: Cook the Potatoes
Preheat your oven to 375°F (190°C). Place the peeled and cubed sweet potatoes in a large pot of water. Bring to a boil and cook for about 15-20 minutes until they are fork-tender. Drain well.
Step 2: Mash and Mix
Add the cooked potatoes to a large mixing bowl. Add the melted butter (or oil), milk, maple syrup, spices, and vanilla. Mash until smooth and creamy. Taste and adjust sweetness if needed. If using the egg, whisk it in last (make sure the potatoes aren’t piping hot so the egg doesn’t scramble!).

Step 3: Make the Topping
In a small bowl, mix the chopped pecans, almond flour (or oats), maple syrup, melted butter, and cinnamon. Stir until the nuts are well coated.
Step 4: Assemble and Bake
Transfer the mashed potato mixture into a 9×13 inch baking dish. Spread it out evenly. Sprinkle the pecan topping generously over the top.
Bake for 25-30 minutes, or until the topping is golden brown and the filling is bubbly. Let it cool for 10 minutes before serving.
Pro Tips for Thanksgiving Prep
We know Thanksgiving Day can be chaotic in the kitchen. Here is how to manage your time:
Make Ahead: You can boil and mash the potatoes up to 2 days in advance. Store the mash in the fridge. On Thanksgiving day, just add the topping and bake (you might need to add 10 extra minutes to the baking time if the mash is cold).
Leftovers: Store leftovers in an airtight container in the fridge for up to 4 days.
Reheating: Reheat individual portions in the microwave, or put the whole dish back in the oven at 350°F to crisp up the topping again.
You Asked, We Answered—Top FAQs
Can I make this vegan?
Absolutely! Simply swap the butter for coconut oil or vegan butter, use plant-based milk (like almond or oat), and skip the egg. It tastes just as delicious.
Can I use canned yams instead of fresh potatoes?
Fresh is always best for texture and nutrition. Canned yams often come in heavy syrup, which adds unnecessary sugar. If you must use canned, buy the “unsweetened” variety and drain them well.
Is sweet potato casserole a side dish or dessert?
Technically, it is served as a side dish with the turkey. However, because it is naturally sweet, it satisfies that dessert craving!
