Why you'll love this recipe
➤ Easier to eat: Many meatball subs use sliced hot dog buns. Often these buns will fall apart under the weight of the cheesy sandwich. We use uncut hoagie rolls instead and hollow out a space for the meatballs right in the buns. Now you can eat your sandwich without fear of the meatballs falling out of the bun or the bun falling apart.
➤ No soggy sandwiches: We slather the rolls with a garlic butter, toast them in the oven and then add a layer of provolone cheese to ensure they hold up to the saucy meatball filling.
➤ Make them in minutes: When you use frozen cooked meatballs and your favorite jarred marinara sauce, you can have meal on the table in just about 30 minutes - perfect weeknight dinner recipe!
➤ Simple recipe to multiply for a crowd: Feeding a large group? This recipe can quickly be scaled for any number of people.
Ingredients
You only need a handful of ingredients for these crowd-pleasing sandwiches.
A few ingredient notes:
- Meatballs: These subs come together in just minutes when you use frozen cooked meatballs, but you can also make your own meatballs from a favorite recipe if you prefer.
- Marinara sauce: We're big fans of Rao's Marinara Sauce but any well-seasoned marinara or pizza sauce will work.
- Buns: Use uncut hoagie rolls or brat buns from the grocery store bakery as you need to hollow out the rolls to make space for the meatballs. Presliced rolls are softer because they are enhanced with preservatives to extend their shelf life. They will fall apart when you try to hollow them out.
Instructions
Start by simmering your meatballs in the marinara sauce until warmed through. While the meatballs are simmering, stir together the butter, garlic and parsley. Salt to taste. Use a serrated knife to cut long rectangle shapes out of the tops of the hoagie buns, being careful not to cut all the way through to the bottom of the buns. Remove the sections of bread you cut out (reserve for another use, if desired, or discard) and brush the cavities with the garlic butter. Toast in a 350°F oven for five minutes.
Line each toasted bun with a slice of provolone cheese. Add four meatballs and some sauce to each bun and top with mozzarella cheese. Bake for another 5 minutes or until cheese is melted. Remove from oven and garnish with grated Parmesan cheese and chopped parsley. Dip sandwiches in any extra sauce from the meatballs.
FAQs
The ingredient list for most meatball subs is pretty short: buns, meatballs, sauce and cheese. We amp up the flavor even more by layering three kinds of cheese on top of toasted garlic butter rolls.
Skip the presliced hot dog or brat buns in favor of uncut hoagie buns from the grocery store bakery. They are usually a bit firmer and will hold their shape better when toasted and filled with saucy meatballs.
We love a zesty marinara sauce but feel free to use your favorite pizza or spaghetti sauce as long as it is robustly flavored.
It may feel like an extra step, but taking a few minutes to toast your rolls before filling them makes a big difference in the sturdiness of your sandwich. Lining the buns with a slice of cheese also helps insulate the rolls from absorbing too much of sauce.
Not well. Once the sandwiches are assembled, they start to soak up the marinara sauce. Toasting the rolls extends the time it takes to absorb the sauce but it doesn't stop it from happening entirely. Our best advice is to assemble only the number of sandwiches you will eat in one sitting.
Expert tips for making the BEST Meatball Subs
✔︎ Use uncut hoagie rolls from the grocery store bakery. They are usually a bit firmer and will hold their shape better when cooked.
✔︎ You can either discard the hollowed out portions of the rolls or reserve them to make homemade breadcrumbs or croutons.
✔︎ Serve any leftover marinara sauce from the meatballs on the side for dipping.
✔︎ Feel free to swap in your favorite homemade meatball recipe for the frozen meatballs in these sandwiches.
✔︎ We use three different types of cheese in these subs (provolone, mozzarella and Parmesan), but feel free to use only one or two if that's what you have on hand.
✔︎ Short on time? Use the slow cooker to simmer the meatballs and sauce all day. All that's left to do when you get home is toast the buns and heat the sandwiches.
