Baked Meatball Subs

Ever find yourself with a craving for something homemade but just don’t have the time to start from scratch? I hear you! That’s why I’m thrilled to share an easy dinner idea that’s about to become one of your favorite recipes:  homemade meatball subs. These subs are not your run-of-the-mill sandwiches—they’re warm, they’re delicious, and they’re on the dinner table in under 30 minutes! 

What’s the secret? Premade frozen meatballs. Don’t knock it until you’ve tried it. They take almost 45 minutes off the cooking time, and can be stored in your freezer to be pulled out when you need something for busy weeknights. They’re my favorite recipe for a busy day!

​Why you want this recipe:

  • quick ‘n easy
  • tastes better than Subway
  • uses basic pantry foods
  • versatile
  • perfect comfort dinner! 

Why frozen meatballs? 

In a word, convenience. 

To be more specific, they save time in multiple ways. These delicious little meatballs can sit in your freezer for months, waiting for their moment to shine. They won’t go bad, and they’ll be there when you need dinner. 

They also take a very short time to cook. Typically, it takes me about 10 minutes to fully cook meatballs from frozen. My own homemade meatballs take me 45 minutes to an hour to mix, form, and bake. Using frozen meatballs is such a timesaver for me!

Another things I love is that the flavor and quality of the meatballs is consistent. I have one extremely picky child, and having foods that are safe and always the same is important here. 

What do I need for meatball sub sandwiches? 

Ingredient for Meatball Subs

​Hoagie Rolls

Hoagie rolls are the shell that holds this together! You can also use hot dog buns for smaller sandwiches. Sandwich rolls and sub rolls also work, and are delicious!

Tomato Sauce

If you’ve never made your own spaghetti sauce, you’re missing out. It takes me just 1 minute more than popping open a can of Ragu, and it tastes delicious! 

That said, if you love your Ragu, or other store-bought marinara you can sub that in here. Just omit the seasonings, since your jar of spaghetti sauce will already have that in abundance!

Italian Seasoning, Garlic Powder, and Pepper

This adds flavor to your tomato sauce, making a fantastic homemade spaghetti sauce. I use shelf-stable herbs and spices in this recipe since I want it to be something I can throw together at a moment’s notice. I like that I can grab seasonings from my pantry to create my own delicious sauce!

Shredded Cheese

Traditionally, shredded mozzarella is the cheese of choice for meatball subs. This recipe is versatile enough that you can get away with using different shredded cheese. You could even use slices of provolone cheese. My kids love a combination of cheddar and mozzarella cheese, which you can see in the pictures. 

Frozen Meatballs

We’ve already talked about the convenience of using frozen meatballs. I prefer to use the Italian meatballs from Great Value. I love the additional Italian taste they lend to my meatball sandwiches. 

You can, of course, sub them with your favorite meatball recipe if you have more time. I love these turkey meatballs from The Recipe Critic. 

How do I make easy meatball subs? 

How to make baked meatball subs

Step 1 | Cook the meatballs

You’ll want a medium-sized saucepan for this. Into the saucepan go your meatballs, tomato sauce, and seasonings. Give them a good stir to mix everything together, then put the lid on. Heat the sauce and meatballs over a medium heat for 5-10 minutes, or until your meatballs have unfrozen. 

Step 2 | Toast the bread

While your meatballs are simmering, lay your hoagie rolls cut side up on a baking sheet. Broil them for 3 minutes on high to toast them. This step is optional, but I highly recommend it since it keeps your subs from getting too soggy. 

Step 3 | Assemble the subs

You can fit 4 subs in a 9×9 pan. Place the bread in the pan, then place the hot meatballs inside each of the hoagie buns. I can fit 5 in each sandwich with the brand of meatballs I use. Spoon extra sauce over the meatballs, then sprinkle the whole thing with cheese. 

Step 4 | Bake

Bake your meatball subs at 400° for 8-10 minutes, or until the cheese melts and is golden and bubbly. Let your sandwiches cool for a a few minutes, then serve warm. You can top them with fresh basil if you’re feeling fancy!

What to serve with meatball subs

If you’re looking for some quick sides to make this a complete meal for busy nights , here’s a few ideas!

Bagged salad 

Your favorite salad recipe will work here, but if you’re short on time, you can grab a bag of salad and open it up for a quick and delicious side. The veggies in the salad are a nutritious addition to this comforting meal!

Veggies

Steamed veggies are super simple, and go great with your subs. Broccoli or green beans would go particularly well!

Fries

Frozen french fries are easy to toss in the oven and have ready when your subs are. Choose from curly, crinkly, seasoned, or steak! If you want to make your own, this recipe is simple and delicious!

Pasta

Boil some pasta and toss it with olive oil and red pepper flakes for a delicious side that leans into the “italianess” of this meal!

Garlic Bread

Storebought garlic bread bakes in just a few minutes. You can also make your own by toasting bread and spreading this simple garlic butter (make it with jarred minced garlic) on top!

How to store leftovers

Bold of you to assume there would even be leftovers! In case you’ve got more than you can enjoy, you can store your leftover sandwiches in an airtight container for up to 2 days. They will get soggier the longer they are in the fridge, so while they might be fine for leftovers tomorrow, this is a dish I recommend you eat as soon as possible. 

Do NOT freeze the finished subs. They don’t hold up well to the thawing process. 

FAQs

What does “sub” stand for in a meatball sub? 

“Sub” is short for “submarine.” This is based on the fact that sub sandwiches look like submarines. You can pull that one out at the next trivia night!

How can I spice up my subs? 

Veggies are a great way to go if you’d like to change up your subs. Bell peppers, red onion, and mushrooms all taste great. You can also try adding red pepper flakes to your sauce if you’d really like to kick the heat up a notch!

What is the best cheese for a meatball sub? 

Provolone is actually the classic choice for a sub. Some folks don’t like the sharper flavor of provolone, and shredded mozzarella is a good choice for them!
