Bubble and Squeak is a traditional English dish, served as a hash of leftover roasted vegetables. It can be made from a variety of vegetables, but potatoes and cabbage are almost always included; it can be served at any meal, and is a common accompaniment to a full English breakfast. This dish was first mentioned in the 1800s, but really fell into its own as a way of elongating meals during World War II, when food rationing was common.
The name “bubble and squeak” refers to the name that the vegetables make as they fry in the pan. There are some similarly fun names for other dishes that share the same technique, like Panackelty (NE England) and Rumbledethumps (Scotland).
Prepared traditionally, Bubble and Squeak is kind of tragic, because that means you could only enjoy it on those rare occasions when you have leftover roasted vegetables in the fridge. As a solution, the recipe below is written using fresh vegetables – you roast the vegetables while you boil the potatoes, then toss them all together for the final, beautiful creation. Of course, if you have leftover vegetables, this recipe will work, too; just skip directly to step #3.
