Potato Casserole Ingredients

For the Casserole

Sweet Potatoes – Fresh sweet potatoes work best for a creamy texture; canned sweet potatoes can be used with proper draining.
Brown Sugar – Adds a deep sweetness; white sugar can substitute, but may alter the flavor slightly.
Eggs – Essential for achieving that rich, custard-like filling; consider using an egg substitute for allergies.
Milk – Use warm milk for optimal blending; non-dairy milk can work just as well.

Vanilla Extract – Adds a lovely layer of warmth and depth to the casserole.
Cinnamon and Nutmeg – These comforting spices bring an inviting aroma to the dish.

For the Topping

Pecans – Toasted pecans enhance the crunch and depth of flavor; walnuts are a good alternative, or omit for a nut-free dish.

Mini Marshmallows – For that sweet, gooey topping—feel free to adjust to your preference or use graham cracker crumbs for a different twist!

Step‑by‑Step Instructions for Grandma’s Comforting Sweet Potato Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). As it warms up, prepare a 9×13 inch baking dish by greasing it with unsalted butter or baking spray. This step ensures your delicious potato casserole won’t stick and will bake evenly, making for a perfect holiday dish.

Step 2: Toast the Pecans
Next, spread your pecans evenly on a baking sheet. Toast them in the preheated oven for about 5-7 minutes, or until they become fragrant and slightly golden. Keep an eye on them to prevent burning, then remove from the oven, chop, and set aside to cool. The toasted pecans will add a delightful crunch and depth to your casserole.

Step 3: Cook the Sweet Potatoes
In a large pot, bring water to a boil. Carefully add your peeled and diced sweet potatoes, allowing them to cook for about 15 minutes, or until they’re fork-tender. Once ready, drain the sweet potatoes and let them cool slightly. This simple step is key to achieving the creamy texture in your potato casserole.

Step 4: Mash the Sweet Potatoes
Transfer the drained sweet potatoes into a mixing bowl and mash them until smooth. Allow them to cool for a few moments, as this will help incorporate the other ingredients better. The sweet potatoes serve as the comforting base of your casserole, bringing a natural sweetness that balances perfectly with the toppings.

Step 5: Prepare the Filling
In a separate bowl, combine softened unsalted butter, brown sugar, all-purpose flour, and warm milk. Mix well until a crumbly texture forms, then fold in a pinch of cinnamon and nutmeg for that familiar holiday aroma. This mixture will add a delicious layer to your sweet potato casserole.

Step 6: Combine the Ingredients
Now, add brown sugar, eggs, milk, vanilla extract, and spices to the mashed sweet potatoes. Mix everything until smooth and well combined. This step ensures that the rich sweetness and spiced flavors are evenly distributed throughout your casserole, enhancing its comforting nature.

Step 7: Layer the Casserole
Pour half of the sweet potato mixture into your greased baking dish and spread it evenly. Next, sprinkle half of the crumbly filling mixture on top, followed by the remaining sweet potato mixture. Repeat the layering with any leftover topping and finish with the toasted pecans and mini marshmallows for that irresistible, gooey finish.

Step 8: Bake the Casserole
Carefully place the assembled sweet potato casserole in the preheated oven and bake for approximately 30 minutes. You’ll know it’s done when the top is golden and bubbly, with marshmallows slightly toasted. If the marshmallows brown too quickly, cover the casserole with foil to prevent burning while the inside cooks through.

Step 9: Serve and Enjoy
Once baked, let the casserole rest for a few minutes to cool slightly and set. Then, serve warm, allowing everyone to enjoy a generous helping of this delightful potato casserole. With its inviting flavors and creamy texture, it’s sure to be a highlight at your holiday gatherings!

Helpful Tricks for Potato Casserole

Choose Quality Potatoes: Fresh, sweet potatoes are essential for achieving the creamy texture and natural sweetness. Avoid canned if possible; if using, drain thoroughly.
Avoid Overcooking: Keep a close watch on the sweet potatoes while boiling. Overcooked potatoes can result in a watery filling for your potato casserole.
Warm Ingredients Matter: Using warm milk and slightly cooled sweet potatoes when mixing contributes to a smooth, well-blended casserole.
Layer Wisely: When assembling, ensure an even distribution of the sweet potato and filling layers for consistent flavor and texture.
Adjust Sweetness: Taste the mixture before baking. Depending on your preference, you might want to adjust the brown sugar.
Make Ahead: Prepare your potato casserole a day in advance and store it in the fridge. Just pop it in the oven before serving for an easy, stress-free holiday dish.

Make Ahead Options

These delightful Sweet Potato Casserole can be prepared ahead of time, making it perfect for busy holiday planners! You can peel and dice the sweet potatoes up to 24 hours in advance; just store them submerged in cold water in the refrigerator to prevent browning. Additionally, the filling mixture can be made and stored in an airtight container for up to 3 days. Assemble the casserole and cover with foil before refrigerating if you prefer this method. When you’re ready to serve, simply bake it straight from the fridge for an additional 5-10 minutes, ensuring it’s heated through and the marshmallows are perfectly toasted, resulting in a comforting dish just as delicious as when made fresh!
