Instructions
- Preheat the Oven:
- Set your oven to 180 degrees Celsius or 350 degrees Fahrenheit Make sure your oven rack is in the center position and grease a 23 by 33 cm baking dish with butter or nonstick spray so nothing sticks
- Cook the Sweet Potatoes:
- Place peeled and chunked sweet potatoes in a large heavy pot Cover with cool water by at least two inches Bring to a rolling boil over medium-high heat then lower to a gentle simmer Boil uncovered for fifteen to twenty minutes until a fork slides in easily Drain thoroughly in a colander so the base stays fluffy not watery
- Mash and Combine:
- Turn sweet potatoes into a large mixing bowl Mash them very well with a masher for a rustic texture or use a hand mixer for a smoother result Add in bourbon milk melted butter brown sugar eggs vanilla cinnamon and salt Mix until the base is completely creamy and homogenous Taste and adjust sweetness or spice if you wish
- Fill the Baking Dish:
- Scrape the sweet potato mixture into your greased baking dish Use a spatula to smooth the top evenly from edge to edge This makes the topping bake up uniformly crisp
- Make the Pecan Streusel:
- In a medium bowl stir together flour brown sugar cold diced butter cinnamon and salt Use a pastry cutter or your fingertips to work the butter into the mix until it looks like small coarse pebbles Fold in the chopped pecans for crunch and rich flavor
- Add the Streusel Topping:
- Sprinkle the prepared pecan streusel over the sweet potato base covering every part as evenly as possible This ensures every serving gets crispy bits
- Bake to Perfection:
- Place the dish in your preheated oven and bake for twenty five to thirty minutes Watch for the topping to turn a lovely golden brown and the filling to be bubbling at the edges This usually signals doneness
- Rest and Serve:
- Remove the casserole from the oven and let it cool for at least fifteen minutes before serving This allows the filling to set makes cutting cleaner and saves you from a molten mouthful

My favorite ingredient here is always the bourbon The first year I doubled the amount by accident and it turned out even better The aroma alone takes me right back to bustling holiday kitchens with generations gathered around

Serve alongside roasted turkey ham or even as part of a holiday brunch A small scoop pairs perfectly with cranberry sauce or a fresh green salad I often top with a few extra toasted pecans for texture or a scoop of whipped cream for those with an extra sweet tooth
Cultural and Historical Context
Sweet potato casseroles are beloved throughout the Southern United States especially at holiday gatherings The historic combo of sweet root veg and nuts was shaped by local crops and available sweeteners Adding bourbon is a regional twist that nods to Kentucky’s rich distilling heritage and lends adult depth to a beloved classic
Seasonal Adaptations
If sweet potatoes are unavailable try garnet yams which bake equally creamy Add a pinch of ground nutmeg or ginger for extra holiday flavor Use maple syrup instead of all the brown sugar for a New England inspired spin
