About the Italian Sausage at Costco

The Italian Sausage is made by Tarantino from San Diego, CA.  These are MILD Italian sausages that will appeal to most palates.

The sausages come in four individual packs with each pack holding five sausages.  This gives you a total of 20 sausages per package.

The general cooking instructions on the packaging are:

  • Place the sausages in a pan with 1/4 inch water.
  • Bring the pan to a simmer.
  • Cover the pan and simmer the sausages for 15 minutes.
  • Uncover the pan and cook until browned.
  • The sausages are done when they reach an internal temperature of 170F.

These instructions are fine but we think grilling them is so much better!

How to Grill

Start by firing up your grill to High heat and preheating the grates for 15 minutes.  I was cooking on a Weber Traveler but the choice of grill isn’t critical.

Reduce the heat to Medium and place the Italian sausages on the grill.

  • Close the lid and grill for two minutes.
  • Open the lid, flip the sausages and repeat.
  • Keep turning the sausages every two minutes and rearranging them on the grill to compensate for any hot spots on the grate.

After the sausages have grilled for 10-12 minutes they will be close to done.

At this point take a sweet bell pepper, slice off the top and bottom then remove the seeds.  Slice the pepper in half and place on the grill with the sausages.

Keep grilling the sausages for 2-4 more minutes until they reach an internal temperature of 170F.

When the sausages are done grilling remove them from the grill and turn the heat back up to High.

Sear the peppers for a few more minutes and add some buns to the grate, face side down, to get them nice and toasty.

When the peppers are seared and tender take them off and slice them lengthwise into matchsticks.

Now it is time to assemble the World’s Greatest Grilled Italian Sausage Sandwich!

  • Place a layer of shredded cheese on the bottom bun.
  • Slice a grilled Italian sausage into medallions and place on top of the cheese.
  • Top the grilled sausage with a handful of the seared pepper matchsticks.
  • Add a dollop of Rao’s marina sauce to the top bun and then stick everything together!

How could that sandwich be anything other than amazing? It’s like lasagna on a bun!
