Rumbledethumps is a Scottish side dish that is a bit like mashed potatoes if they were made into a casserole with cabbage, turnips, and cheese. I love all of those, so this is like comfort food from my ancestors. I love learning about the traditional foods from my heritage and since the Scottish aren’t necessarily known for their cooking, I was happy to discover this gem.


After trying this dish, you may never go back to regular mashed potatoes! I love the extra flavor texture from the cabbage and cheese. This also makes amazing leftovers, so you may want to make an extra batch to freeze.
