These mashed purple sweet potatoes are a simple side dish with serious wow factor, thanks to their deep violet color and rich, buttery flavor. Finished with nutty browned butter and a splash of cream, they’re silky, cozy, and always a conversation starter at the table.
These mashed purple sweet potatoes are one of my favorite ways to dress up a simple side dish. Their deep violet color always turns heads at the table, but it’s the flavor that really seals the deal. Rich, earthy sweet potatoes mashed smooth and finished with browned butter feel special without being fussy.
Browning the butter is what makes these unforgettable. As it cooks, it takes on a toasty, caramel-like aroma that pairs beautifully with the naturally sweet, dense purple potatoes. A splash of cream (or milk) softens the texture just enough, creating mash that’s silky and spoonable without losing its body.
I love serving these when I want something familiar with a twist—especially for holiday meals or dinner parties where they spark a little curiosity. They’re simple, striking, and packed with cozy, buttery flavor that keeps people coming back for another scoop.
