The Bomb Italian Sausage Sandwich Recipe

The Bomb Italian Sausage Sandwich! And yes—it’s the Bomb. Roasted Italian sausage links are baked, smothered in red sauce and spicy, melty pepper jack cheese, then toasted inside crusty French-style Italian bread until everything is gooey and golden.

This cheesy, spicy, saucy—and delightfully messy—Italian sausage sandwich is a family favorite that brings back memories every time. It’s a comforting, crowd-pleasing meal that works for a simple weeknight dinner or as a hearty offering for game day and gatherings.

My dad first discovered this sandwich after he and my mom moved to St. Louis in 1977. St. Louis still has a strong Italian neighborhood known as The Hill, and nearby there was a small Italian delicatessen called Grassi’s. One of their signature items was known as The Bomb: a poor-boy style sandwich filled with lengthwise-sliced Italian sausage, pepper jack cheese and red sauce, wrapped in foil and toasted. Our home version stays true to that original idea while being easy to prepare at home.

How to make The Bomb Italian Sausage Sandwich

For a family-style version I typically use two large loaves of crusty Italian bread, sliced lengthwise. Authentic, bakery-style Italian loaves give the best texture, but any sturdy crusty bread will work.

Using a homemade red sauce will elevate the sandwich—thick, well-seasoned tomato sauce melds perfectly with the sausage and cheese. If you prefer convenience, a high-quality store-bought marinara will do; just choose one with good flavor and texture.

While the sauce simmers, arrange ten Italian sausage links on a cookie sheet and bake at 350°F (175°C) for about 30 minutes, turning once, until cooked through and browned on both sides. Remove and let the sausages cool slightly before handling.

Can I use premade marinara or red sauce instead of homemade?

Yes. Choose the best-quality jarred sauce you can find. A rich, well-seasoned marinara will still deliver great results if you don’t have time to make your own.

When the sauce and sausages are done, let them rest for about 10 minutes. Slice a pound of pepper jack cheese into thick slices. Slice each sausage lengthwise, then crosswise so each link yields four pieces—this helps the sausage lay flat in the sandwich.

Place the halved loaves on a large cookie sheet, spread sauce on both cut sides, then arrange the cheese on the top halves and the sausage pieces on the bottom halves. Carefully bring the two halves together to form the loaves, then wrap the loaves tightly with foil.

Bake the wrapped loaves at 350°F (175°C) for 15–20 minutes, or until the cheese is fully melted and the sandwich is heated through. Remove foil, slice into sandwich-sized portions with a serrated bread knife, and serve. For a main course, pair the sandwiches with a crisp Italian salad; for parties, cut into narrower strips for easy finger food.

Ingredients (serves about 10)

2. Prepare your red sauce (homemade or jarred) and keep warm.
3. Arrange sausage links on a baking sheet and bake for 30 minutes, turning once, until browned and cooked through. Let cool slightly.
4. Slice each sausage link lengthwise then crosswise to make four pieces per link.
5. Slice the pepper jack cheese into thick slices.
6. Slice Italian loaves lengthwise and place both halves on a large cookie sheet.
7. Spread sauce across the cut sides of both halves. Arrange cheese on the top halves and sausage pieces on the bottom halves.
8. Carefully close the loaves, pressing top and bottom together, then wrap tightly in foil.
9. Bake wrapped loaves for 15–20 minutes, until the cheese melts and the sandwich is heated through.

Notes

This sandwich is versatile: swap pepper jack for provolone or mozzarella for a milder option, or add sliced roasted peppers or sautéed onions for extra flavor. For a bit of crisp, uncover the foil for the last few minutes of baking to lightly toast the crust.
