Italian Sausage Sandwich

Italian Sausage Sandwich – sausages simmered in tomato sauce with peppers and onion until they melt in your mouth, sandwiched between buns, then loaded with oozing, gooey mozzarella cheese!

Back in Chicago this Italian sausage sandwich is known as the bomber sandwich.

They’re surprisingly easy to make with just a few ingredients, but flavorful results. 

Plus, they’re a hit with everyone and great for parties!

We also love this Sausage and Peppers Pasta which is ready in just 30 minutes!

Italian Sausage Sub Ingredients:

  • Italian sausages – you can use mild or spicy. I prefer spicy!
  • Tomato puree – make sure to use a large can or two small ones
  • Peppers & onions – these melt into the tomato sauce and give it incredible flavor. Don’t skip out even if you don’t put them on the sandwich itself!
  • Mozzarella cheese – get a block and shred it yourself for maximum gooeyness!
  • Buns – hotdog buns won’t be sturdy enough for these substantial subs. If you’re in the Chicago area try to get Turano rolls or use French bread.
  • Hot peppers or giardiniera – if you want to spice things up these are great toppings!

Italian Sausage and Peppers Sandwich

This recipe is especially meaningful to me because it was passed down from my dad.

He makes his own sausage for these bombers, but I’ve simplified it by using Italian sausage links.

My dad simmers his on the stove for hours with peppers and onions, until the sausage takes on a buttery, melt-in-your-mouth quality.

With my version, you can pop everything in the slow cooker where it will cook and then stay warm until ready to eat.

If you prefer stovetop, I’ve included those instructions below as well.

These sandwiches aren’t called bombers for nothing! Serve with extra sauce if you like and enjoy the perfection that is meat, cheese and bread in one bite.
