Bangers and Mash is a super simple dish, yet one of the most satisfying and comforting meals you can have. Perfectly cooked pork bratwurst sausage over buttery mashed potatoes smothered in onion gravy totally hits the spot on a cool evening.
Bangers get their name because they would splatter in the skillet, sounding like mini explosions that sounded like a "bang."
There are a lot of variations in the ways to prepare the bangers and the onion gravy. I prefer to keep mine simple and cook the onions with the sausage, which adds extra flavor to the onions, along with saving on cooking time. After browning, covering the skillet will steam the sausage and cook them faster without drying them out.
Instead of adding a lot of extra ingredients to the gravy, I like to use a high-quality and flavorful beef bone broth, which is really where a ton of the flavor of the sauce comes from. This onion gravy isn't a thick gravy like that which is often served with turkey. It's pretty thin, but packs lots of wonderful onion flavor that mixes so great with the buttery mashed potatoes.
