This cozy brown butter sweet potato casserole with candied pecan streusel was born from a distracted afternoon and a pan of butter I thought I’d ruined. Now, it’s the dish I’m most proud of, the one I bring to every fall gathering, and honestly, the one that makes me close my eyes after the first bite every single time.
For the best brown butter, use a light-colored pan and watch it closely—it goes from perfect to burnt in about 30 seconds. Let the sweet potatoes steam dry after draining to avoid a watery mash. The casserole can be assembled up to 2 days in advance and refrigerated; add 5-10 minutes to the baking time if baking from cold. Leftovers keep in the fridge for up to 4 days and freeze well for up to 3 months.
