My sister in law brought this viral comfort food to the summer potluck and it is ridiculously good

My sister-in-law showed up to our small-town summer potluck with this big glass dish of oven baked 5-ingredient grinder sandwich pasta, and it disappeared before the potato salad even had a chance. It tastes like one of those old-fashioned Italian grinder subs from the corner deli—creamy, tangy, and packed with salty salami and melty provolone—but turned into an easy baked pasta you can scoop with a wooden spoon. It’s the kind of viral comfort food that makes its way through church basements and family reunions, because it’s simple, hearty, and feels like a hug in casserole form.

Serve this grinder sandwich pasta hot from the oven with a crisp green salad—something with romaine, cucumbers, and a sharp vinaigrette to cut through the richness. Garlic bread or buttered Texas toast fits right in, and a side of dill pickles or pepperoncini gives that deli-sandwich crunch and tang. It travels well, so it’s perfect for potlucks alongside baked beans, coleslaw, and a pan of brownies or a fruit salad for dessert.

Servings: 6

12 oz dry short pasta (ziti, penne, or rotini)

Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch glass casserole dish and set it aside.

Bring a large pot of salted water to a boil. Add the pasta and cook just to al dente according to the package directions; you want it with a little bite so it holds up in the oven. Drain well and return the pasta to the warm pot.

While the pasta cooks, chop the salami into thin strips or small bite-size pieces. Halve the cherry tomatoes (or dice the Roma tomatoes) so they mix easily into the pasta.

To the warm drained pasta in the pot, add the chopped salami, halved tomatoes, 2 cups of the shredded provolone, and the creamy Italian or sub/grinder dressing. Stir gently but thoroughly until everything is well coated and the cheese starts to get a little creamy from the warmth of the pasta.

Taste a noodle and a bit of salami; if it seems like it could use a pinch of salt or pepper, you can add it now, but remember the salami and dressing are already salty and seasoned.

Spoon the pasta mixture into the prepared glass casserole dish, spreading it into an even layer. Use the back of the spoon to tuck any big pieces of salami down into the pasta so they don’t scorch on top.

Sprinkle the remaining 1 cup shredded provolone evenly over the top of the pasta, covering as much of the surface as you can for a good cheesy crust.

Cover the casserole loosely with foil, tenting it slightly so it doesn’t stick to the cheese. Bake in the preheated oven for 20 minutes, until the pasta is heated through and the cheese underneath is starting to melt.

Remove the foil and continue baking for another 8–12 minutes, or until the top is bubbly and the provolone is melted and just starting to get golden in spots. If your oven runs hot, start checking around the 8-minute mark so the cheese doesn’t get too dark.

Carefully remove the dish from the oven and let it rest on a cooling rack or trivet for about 10 minutes. This helps the pasta set up a bit so it scoops nicely and doesn’t slide all over the place.

Serve straight from the glass casserole dish with a sturdy wooden spoon, making sure each scoop has some pasta, melted provolone, salami, and tomatoes. It should look creamy and a little messy, just like a good grinder sandwich turned into a bubbling, comforting bake.

You can easily tailor this grinder sandwich pasta to what you have on hand or what your family likes. Swap the hard salami for pepperoni, ham, or a mix of Italian cold cuts for a more classic deli flavor. If you prefer things a bit spicier, use hot capicola or spicy salami and add a spoonful of sliced pepperoncini or banana peppers into the mix before baking. For a slightly lighter version, choose turkey salami and a lighter creamy Italian dressing, and cut the cheese back to 2 cups total. If you don’t have provolone, mozzarella works nicely, or use a half-and-half mix of the two. You can also stir in a handful of thinly sliced red onion or shredded iceberg lettuce right after baking for a nod to the classic grinder toppings—just know the lettuce will soften quickly, so add it only to what you’ll eat right away. For make-ahead prep, assemble the casserole up to the point of baking, cover tightly, and refrigerate for up to 24 hours; add an extra 5–10 minutes to the covered baking time if it goes into the oven cold. Food safety tips: keep the salami refrigerated until you’re ready to use it, and don’t leave the baked casserole out at room temperature for more than 2 hours (or 1 hour if it’s very hot out at a picnic or potluck). Cool leftovers promptly, cover, and refrigerate; they’ll keep safely for about 3–4 days. Reheat portions in the oven or microwave until steaming hot in the center, and discard any leftovers that have sat out too long or show off smells, off colors, or slimy texture.
