Bangers & Mash with Guinness Gravy is pub fare fit for a St. Patrick's Day celebration or whenever the comfort food notion strikes!
To a large cast iron skillet over medium-high heat, add the olive oil. When the oil begins to shimmer, carefully add the sausages and slowly pour on the stout. Reduce the heat slightly and cover with lid. Crack the lid just to allow enough steam to escape. Cook the sausages and stout covered for about 10 minutes, turning halfway through.
In a separate deep skillet, heat butter over medium high heat. Add the sliced yellow onions and reduce the heat to medium low. Cook until lightly golden and very fragrant, about 20 minutes. Add the fresh thyme leaves and stir for a minute until the thyme becomes aromatic.
Fill a large pot with water and 1 tablespoon of Kosher salt. Add prepared potatoes and bring to a boil. Cook potatoes until they become somewhat soft.
