• Granulated Sugar – Sweetens the filling; feel free to adjust the quantity for a less sweet pie.
• Brown Sugar – Adds moisture and depth; coconut sugar can be used for a richer flavor.
• Evaporated Milk – Ensures creaminess; substitute with heavy cream for richness or coconut cream for a dairy-free option.
• Eggs – Provide structure; using room temperature eggs helps with better mixing.
• Vanilla Extract – Elevates flavor depth; pure vanilla extract is recommended for an aromatic quality.
• Ground Cinnamon – Infuses warmth and spice; it’s a key flavor in Grandma’s Secret Sweet Potato Pie.
• Ground Nutmeg – Complements the cinnamon; consider fresh nutmeg for enhanced flavor.
• Salt – Balances out the sweetness; a small pinch enhances the overall taste.

Step‑by‑Step Instructions for Grandma’s Secret Sweet Potato Pie
Step 1: Prepare Sweet Potatoes
Start by bringing a large pot of water to a boil. Add 2 large sweet potatoes and cook them for about 30 minutes until they’re tender when pierced with a fork. Once cooked, carefully drain the water, peel the sweet potatoes, and mash them until smooth with a potato masher or fork for a creamy base in Grandma’s Secret Sweet Potato Pie.
Step 2: Mix Filling
In a large mixing bowl, combine the mashed sweet potatoes with granulated sugar, brown sugar, evaporated milk, eggs, vanilla extract, ground cinnamon, ground nutmeg, salt, and melted unsalted butter. Using an electric mixer, blend the mixture on medium speed for about 2-3 minutes until smooth and well combined. The sweet potato filling should be velvety and slightly fluffy.
Step 3: Prepare Crust
If you’re using a pre-made pie crust, place it into a 9-inch pie dish, gently pressing it into the edges. If you prefer a homemade crust, prepare it according to your favorite recipe, ensuring it’s chilled and rolled out to fit the dish well. The crust should feel firm yet soft, providing a perfect base for your Grandma’s Secret Sweet Potato Pie.
Step 4: Assemble
Pour the creamy sweet potato filling into the prepared crust, using a spatula to smooth the top evenly. Make sure the filling is distributed well to avoid any bubbles which can cause cracking as it bakes. The vibrant orange filling should look inviting and luscious in the crust.
Step 5: Bake
Preheat your oven to 350°F (175°C). Once hot, place the assembled pie in the center of the oven and bake for approximately 50 minutes. You’ll know it’s ready when the filling is set and a toothpick inserted into the center comes out clean. The edges should be lightly golden and firm to the touch.
Step 6: Cool
After baking, carefully remove the pie from the oven and let it cool on a wire rack for at least 1 hour. This cooling time allows the filling to set properly, which is essential for slicing. The enticing aroma of your Grandma’s Secret Sweet Potato Pie will fill your kitchen as it cools.

Make Ahead Options
These Grandma’s Secret Sweet Potato Pie is perfect for busy home cooks looking to save time! You can prepare the sweet potato filling and store it in an airtight container in the refrigerator for up to 3 days. To maintain the pie’s delightful texture, refrigerate the filling separately from the crust, as this prevents sogginess. On the day you wish to serve, simply pour the chilled filling into the pre-made or baked crust, smooth the top, and bake it as directed. This makes it easy to have warm, comforting pie ready in no time, and it’ll taste just as delicious as if you had made it fresh that day!
Helpful Tricks for Grandma’s Secret Sweet Potato Pie
• Sweet Potato Quality: Choose ripe, fresh sweet potatoes for best flavor; avoid overcooking to maintain the creamy texture of your filling.
• Mixing Technique: Be gentle when mixing the filling; overmixing can lead to cracks in your pie. Just blend until smooth and combined.
• Pre-bake the Crust: Prevent a soggy bottom by pre-baking your pie crust for 5-10 minutes before adding the filling; this keeps it flaky.
• Check Doneness: Use a toothpick to test if the filling is set; it should come out clean without wet batter sticking for a perfect Grandma’s Secret Sweet Potato Pie.
• Cooling Time: Allow the pie to cool for at least 1 hour before slicing; this helps the filling firm up for cleaner slices and enhanced flavors.
