Grilled Bangers and Mash - Happy St. Patrick's Day!

Nothing says St. Patrick's Day like the rich, hearty flavors of a traditional Irish meal. Grilled bangers and mash bring that pub-style comfort to your backyard, combining smoky, juicy sausages with buttery mashed potatoes and savory onion gravy. This dish is rustic, satisfying, and made for gathering around the table with friends and family.

While the classic version calls for pan-fried sausages, grilling takes them to another level. A kiss of flame intensifies their natural richness, crisping the casing while keeping the inside tender and juicy. Instead of relying on a stovetop, fire up the grill and let the heat work its magic. The high temperatures create a perfect char, locking in flavor and adding a smoky depth that balances the creamy, indulgent potatoes.

No bangers and mash would be complete without a rich, velvety gravy. This one is slow-simmered with caramelized onions, beef stock, and a splash of stout, giving it a deep, malty complexity. Drizzled over the grilled sausages and buttery potatoes, every bite delivers warmth and satisfaction, perfect for a cool evening or a festive gathering.

This recipe keeps things simple but bold—quality ingredients, time-honored flavors, and the unmistakable touch of live-fire cooking. Fire up the grill, pour a pint, and serve a plate of comfort that honors the flavors of Ireland while embracing the joy of cooking outdoors.

Grilled Bangers and Mash Directions

Grilled Bangers

  1. Heat the grill to high (400 degrees F). Place the sausages on the grill, reduce the heat to medium-high (around 325 degrees F), and cook, turning frequently, until the sausages are cooked through. 
  2. Refer to the package cooking temperature directions: about 15 minutes. The time will vary according to the cooking temperature, grill type, and sausage variety.

Country Mashed Potatoes

  1. Place washed, peeled, and cubed potatoes in a large pot. Use large chunks of potatoes if you like chunky mashed potatoes and smaller if you like smooth potatoes. Cover with cold water, and bring to a boil over high heat.
  2. Bring to a boil and cook for approximately 10 - 15 minutes until you can easily poke through a potato with a knife. Drain well, and return to the hot pan. The secret to great fluffy mashed potatoes is getting the liquid out. Returning them to the pan helps dry them out.
  3. Add butter, salt, pepper, and half of the milk. With a fork or potato masher, mash the potatoes to the desired consistency. Add more milk, salt, and pepper, and continue to mash. Taste and season as needed. Keep in mind that the bangers will be salty, so don't overdo it.

Grilled Onions

  1. In a skillet, melt butter over medium-high heat. Add onions and let cook. Don't touch them; just watch your heat. When they get brown, stir them and leave them alone. Again, you really want to get a nice brown color on the onions.
  2. When they are brown, add salt and pepper to taste. (Use sparingly; you can always add more.) Reduce heat to medium-low and cook until caramelized and tender, about 10 minutes.

Gravy

  1. Remove the onions from the skillet. Melt butter in the same skillet over medium heat. Add flour and stir to combine. Cook and stir for 5 minutes, slowly browning the flour mixture. Do not let it burn.
  2. Slowly add water, a little at a time, continuously stirring until all lumps are gone.
  3. Add more water and stir until desired consistency. Add salt and pepper to taste.
  4. Serve potatoes with gravy, topped with sausage and onions, and a side of green peas.
