This mouth-watering grilled sausage sandwich is guaranteed to quickly become a crowd favorite.

It’s packed with juicy grilled pork sausage, featuring our favorite grill marks, and topped with beautifully sautéed onion, peppers, and a sliver of mustard.

All housed in a toasted baguette. These are dangerously addictive and will go down a storm on game day as part of your tailgate.

Let the obsession begin.

What’s great is that these sandwiches are made with just a few core ingredients:

  • Italian sausage
  • Red pepper
  • Red onion
  • Fresh baguette

You simply sauté the onion and pepper for about ten minutes, before grilling the star of the show: The Italian sausage.

Different people have their own choice of sausage for this kind of recipe, but I just find that Italian just strikes the right balance between traditional meat flavors, as well as herbs and added seasoning.

For more topping ideas, try adding homemade sauerkraut or smoked pastrami to the fold. It’ll be a mouthful, but boy will it be packed full of flavor!

How to Grill Sausage

One of the best things about sausages is how easy they are to cook. Just like other BBQ classics like burger patties and chicken breasts, they only need a few minutes on either side.

Heat up your grill to about 450-500°F (230-260°C). Once your grill has reached temperature, place your sausages on the grill close to the heat. Cook for about 5-6 minutes, until that side has started to turn brown. Turn the sausages over and cook for another 5-6 minutes. Continue to grill until cooked through (this might require a further 2-3 minutes). Aim for an internal temperature of 160°F.

Remove meat from grill and serve immediately!

Time & Temperature

Grill over high heat, about 450°F-500°F on your gas grill. It takes about 6 minutes per side, taking 12 minutes in total to grill sausages until they are cooked through.
