Bangers and Mash with Stout Onion Gravy is a traditional quick and easy dinner made from sausages, buttermilk mashed potatoes, and a savory gravy loaded with onions. This recipe originated from the British Isles and can be made with any kind of sausage. The Irish Stout adds intense flavor to the sausage and the gravy.
Heat oil in a skillet over medium high heat. Add sausages and stout. Cover with lid and crack just to allow enough steam to escape. Cook covered for about 10 minutes, turning half way through.
After they've cooked for 10 minutes, remove lid and allow the liquid to reduce a bit and coat the sausages. When the liquid is almost gone, lower heat to medium low and continue cooking with the lid on, rotating occasionally, until evenly browned and cooked through, about another 10 minutes.
gravy:
In a separate pot, heat butter over medium high heat. Add sliced onions and cook until slightly brown and fragrant, 5-10 minutes. Sprinkle with flour and allow to cook 2-3 minutes.
Add stout and scrape bottom of pan to deglaze. Add beef broth and allow to simmer until no longer foamy, 10-15 minutes.
potatoes:
In large pot cover potatoes with water and bring to a boil. Cook until soft. Drain and add butter and buttermilk. Mash to your preferred consistency.
To serve, top potatoes with sausage(s) and top with as much gravy as your heart desires.

Notes
Cooking tips:
Sometimes it's easier to find sausages that are pre-cooked. You can use these as well. Just ensure they get heated through.
You can use any kind of beer. Stout tastes great with the onions, but a nice wheat ale would also work.
The less frequently you stir the onions, the better they will brown.
