Step-by-Step Instructions
Here’s how to make the perfect Sweet Potato Casserole from scratch:
Step 1: Prepare the Sweet Potatoes
1️⃣ Peel and cube the sweet potatoes into bite-sized pieces. Place them in a large pot of water.
2️⃣ Boil the sweet potatoes over medium heat until they are soft (about 15-20 minutes). You can easily test by piercing a piece with a fork.
💡 Pro Tip: Drain the sweet potatoes well to avoid excess water, which can make the casserole too runny.
Step 2: Mash the Sweet Potatoes
3️⃣ Once the sweet potatoes are soft, mash them with a potato masher or a hand mixer until smooth.
4️⃣ Add the butter, brown sugar, salt, cinnamon, and vanilla extract to the mashed sweet potatoes. Stir everything together until it’s creamy and well combined.
5️⃣ Beat the eggs in a separate bowl and then fold them into the mashed sweet potatoes mixture. Add milk and continue to mix until the casserole base is smooth and creamy.
💡 Pro Tip: Adjust the sweetness to your preference by adding more brown sugar if you like it sweeter!
Step 3: Prepare the Topping
6️⃣ In a separate bowl, combine the pecans, mini marshmallows, melted butter, brown sugar, cinnamon, and crushed graham crackers.
7️⃣ Mix until everything is evenly coated.
💡 Pro Tip: If you prefer less sweetness, use fewer marshmallows or pecans, and keep the topping more minimal.
Step 4: Assemble & Bake
8️⃣ Preheat the oven to 350°F (175°C).
9️⃣ Transfer the sweet potato mixture into a greased 9×13-inch baking dish, spreading it evenly.
🔟 Top the casserole with the pecan and marshmallow mixture, making sure to cover the entire top.
💡 Pro Tip: If you want a more caramelized topping, sprinkle a little extra brown sugar on top before baking.
11️⃣ Bake the casserole for 25-30 minutes, until the topping is golden brown and the casserole is bubbling.
