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

Mash and Combine:

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

Storage Tips

Cover leftovers tightly with foil or store in an airtight container in the fridge It keeps well for three to four days When reheating bake covered in the oven at 160 degrees Celsius until hot or zap brief portions in the microwave The topping is crispiest when reheated in the oven

Ingredient Substitutions

For a nonalcoholic version use orange juice or extra milk instead of bourbon No pecans Swap in walnuts or use pumpkin seeds for a nut-free crunch Need gluten free Choose a one to one gluten free flour blend for the topping and nobody will know the difference

Serving Suggestions

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
