📖 Instructions

1. Prep Your Spuds: Begin by preheating your oven to 375°F (190°C). Grab those beautiful sweet potatoes—peel them thoroughly, then chop them into roughly 1-inch cubes. This uniform size helps them cook evenly.
2. Boil 'Em Up: Place your chopped sweet potatoes into a large saucepan. Cover them with cold water, adding about an inch of water above the potatoes. Throw in a pinch of salt to the water; it really helps bring out their natural sweetness. Bring the water to a boil over medium-high heat, then reduce the heat to a simmer, cover the pot, and let them cook for about 15-20 minutes. You'll know they’re ready when they're fork-tender—meaning a fork slides into them with almost no resistance.
3. Drain and Mash: Carefully drain the cooked sweet potatoes in a colander. Return the hot potatoes to the saucepan or transfer them to a large mixing bowl. Now for the fun part! Using a potato masher, or an electric hand mixer for an extra smooth consistency, mash those sweet potatoes until they’re lump-free and wonderfully creamy.
4. Whip Up the Filling: To your mashed sweet potatoes, add the softened butter, brown sugar, milk or cream, vanilla extract, and salt. Give it all a good mix until everything is well combined and the mixture is smooth. Taste it here! This is your chance to adjust the sweetness or add a little more vanilla if you feel it needs it. Next, crack in the two large eggs and mix them thoroughly until they are fully incorporated into the sweet potato mixture. The mixture should be a lovely, uniform orange color.
5. Into the Dish: Spoon your creamy sweet potato filling into a 9x13 inch baking dish that you've lightly greased. Spread it out evenly with a spatula. Don't worry about making it perfectly flat; a little texture is fine.
6. Craft the Caramelized Pecan Topping: In a separate small mixing bowl, combine the chopped pecans, remaining brown sugar, all-purpose flour, and melted butter. Use a fork or your fingers to mix these ingredients together until crumbly. It should resemble coarse wet sand. This is where the magic happens for that golden crunch!
7. Top it Off: Sprinkle the pecan streusel topping evenly over the sweet potato filling in the baking dish. Make sure it covers most of the surface.
8. Bake to Perfection: Pop the baking dish into your preheated oven. Bake for 30-35 minutes, or until the sweet potato filling is heated through and slightly puffed, and the pecan topping is beautifully golden brown and caramelized. Keep an eye on the topping in the last 10 minutes; if it's getting too dark, loosely tent the casserole with aluminum foil.
9. Rest and Serve: Once baked, carefully remove the casserole from the oven. Let it rest for about 10-15 minutes before serving. This brief rest allows the casserole to set slightly and makes for cleaner serving. Then, scoop out generous portions and enjoy the incredible flavors of this comforting classic!
