Start by slicing the sausages and chopping the bacon, onions, and potatoes. Use a large pot or Dutch oven for this hearty Dublin Coddle. Once everything is prepped, layer the sliced sausages, chopped bacon, and onions at the bottom, followed by the potatoes for a structured base.

If you’re including optional vegetables like carrots or leeks, sprinkle them on top of the layered ingredients. This creates an inviting look and ensures even cooking.

Carefully pour the chicken or vegetable broth over the layered ingredients until they’re just covered. If you're using mustard, stir it in at this point for added flavor complexity.

Bring the pot to a gentle simmer over medium heat. You’ll see small bubbles forming, signaling the stew is starting to come together. Once it begins to simmer, reduce the heat to low to maintain a slow cook.

Cover the pot and let it cook for about 1 hour, stirring occasionally. Keep an eye on the stew; you want the potatoes to be tender and the broth to thicken slightly.

After an hour, test the potatoes with a fork for tenderness. Once they’re soft, check the seasoning, adjusting with salt and pepper as needed.

Ladle the Dublin Coddle into bowls and serve hot. Pair it with crusty bread to soak up the savory broth.
