Slow Cooker Bangers & Onions with Just 4 Ingredients
This slow cooker 4-ingredient Bangers and Onions is the kind of simple, hearty dish my Irish grandfather would have made in March—just a few ingredients, slow cooking, and big, satisfying flavor. Sweet onions form a soft bed for classic Irish sausages, slowly turning into a rich, savory gravy. With minimal effort, you get sausages so tender they practically fall apart under your fork, coated in a glossy sauce that tastes like you spent hours fussing.
It’s pure comfort food—perfect for St. Patrick’s Day but easy enough for any weeknight dinner.
Serve over buttery mashed potatoes so the gravy can soak in, and pair with steamed cabbage or sautéed greens for a balanced plate. Crusty bread is a must for mopping up the last drops. For drinks, a malty Irish red ale or stout is ideal, though a dry cider or crisp salad works just as well.
