- 2 tbsp dried oregano
- 1 tbsp garlic powder
- 1 1/2 tsp onion powder
- 1 1/2 tsp dried parsley
- 1 1/2 tsp dried basil
- 1 tsp kosher salt

- 1/2 tsp celery seed
- 1/2 tsp cayenne
- 1/2 tsp sugar
- 1 tbsp beef bouillon base
- 1 x 6-oz can tomato paste
- 1 x 28-oz can crushed tomatoes

- 32 oz frozen meatballs
For Subs:

- 12 French rolls

How to Make The Best Meatball Sub Recipe for a Crowd
Step 1. Begin by heating the olive oil in a large pot over medium heat. Add the chopped onion and sauté until it becomes very soft, about 5-7 minutes. This will help develop the flavor base for your sauce.
Step 2. Once the onion is soft, add the minced garlic along with the dried oregano, garlic powder, onion powder, dried parsley, dried basil, kosher salt, ground thyme, celery seed, cayenne, and sugar. Cook for another 1–2 minutes, allowing the spices to release their aromas.
Step 3. Stir in the beef bouillon base and tomato paste, mixing well. Then, add the crushed tomatoes, diced tomatoes, and tomato sauce. This combination will create a rich and flavorful sauce to coat the meatballs.
Step 4. Next, add the frozen meatballs to the simmering sauce. Stir gently to ensure they are well-coated. You can either cover and simmer on the stovetop for about 1 hour or transfer to a slow cooker and cook on Low for approximately 4 hours. Both methods will thoroughly heat the meatballs and allow the flavors to meld.
Step 5. When the meatballs are almost done, preheat your broiler. Slice the French rolls open and place them on a baking sheet. Toast the rolls under the broiler until lightly browned, then top with sliced mozzarella or Provolone cheese. Broil until the cheese is melted and bubbly.
Step 6. Fill each toasted roll with meatballs and sauce. If desired, add more cheese on top and briefly broil again to melt it. Your delicious meatball subs are now ready to serve!

Serving Suggestions
These meatball subs are perfect as a main dish for a casual gathering, birthday party, or game day. Consider serving them with a simple side salad for contrast or some crispy potato chips for added crunch. They’re also great with a side of pickles or coleslaw to balance the rich flavors of the meatballs and cheese. For a fun twist, you can set up a toppings bar with various cheeses or fresh herbs, allowing guests to customize their sandwiches to their liking.
Pro Tips for Best Results
- Sautéing onions properly ensures a depth of flavor. Don’t rush this step; allowing them to become soft will make a difference.
- Don’t skip toasting the rolls. This adds a delightful crunch that contrasts beautifully with the softness of the meatballs and sauce.
- Choose quality cheese. Fresh mozzarella or Provolone can make a substantial impact on flavor—opt for a brand that you enjoy.
- Adjust seasoning to your taste. Feel free to taste and tweak the sauce as it simmers; each palate is different.
- For a richer sauce, add a splash of red wine or balsamic vinegar while it simmers.
Common Mistakes to Avoid
Not sautéing the onions long enough: If the onions are still crunchy, the flavor won’t be as rich. Make sure to cook them until they are very soft.
Overcooking or undercooking the meatballs: If you don’t heat them through thoroughly, they won’t absorb the sauce’s flavors; however, overcooking can dry them out. Stick to the recommended cooking times.
Skipping the toasting step: Toasting the rolls is essential for a great texture. If you skip it, they may become soggy once filled.
Adding too many spices at once: If you throw everything in without giving each spice time to bloom in the oil, the flavor won’t develop fully. Add spices gradually after the onions.
Not letting the sauce simmer properly: Skipping the simmering step means the flavors won’t meld, leading to a bland sauce.
Filling rolls too generously: It can be tempting to overstuff your subs, but too much filling can lead to a messy eating experience. Aim for a balanced amount.
Variations & Substitutions
This recipe can be easily customized based on your preferences. For instance, if you’re looking for a different flavor profile, you can swap out the mozzarella for spicy pepper jack cheese to add some heat. Alternatively, you can use different herbs, such as fresh basil or rosemary, instead of dried versions for a fresher taste. However, no additional substitutions are specifically provided in this recipe.
Storage & Reheating
Leftover meatball subs can be stored in the refrigerator for up to 3 days. It’s best to keep the meatballs and sauce separate from the rolls to maintain their texture. When reheating, place the meatballs and sauce in a saucepan over low heat until warmed through, and toast the rolls separately. For longer storage, you may freeze the meatballs and sauce for up to 3 months. Just thaw in the refrigerator before reheating.
