Homemade Meatball Subs (with Cheese Stuffed Meatballs)

These Subs are made with an Easy Marinara Sauce and Juicy Homemade Meatballs that are stuffed with mozzarella cheese!

My go-to order at Subway is the Meatball Marinara, without fail. This recipe simply came about because I was spending so much at Subway and thought it could surely be replicated. Well my friends, it certainly can. Follow me…

Homemade Meatballs

I’ve written a more in-depth post called how to get soft and juicy meatballs, so do check that out if you fancy. But throughout this post, I’ll give you the basic run down, so not to worry.

Cheese Stuffed Meatballs

For this recipe, I’ve decided to take things to the cheese extreme and stuff the meatballs with cheese. Because why the heck not? Just make the meatball mixture as you usually would, grab a cherry mozzarella ball and roll it in the centre. Then cook as you usually would and reap the reward of each meatball having an oozy cheesy centre!

Easy Marinara Sauce

This is a fairly easy recipe all round, but just like the meatballs, it’s too easy not to make your own marinara sauce. Also just like meatballs, the difference between store-bought and homemade marinara sauce is crazy!

How to make cheese stuffed meatballs in sauce (quick summary)

1. Create your meatball mixture, split into 20 even pieces and place a mozzarella ball in each one.
2. Roll into a ball, ensuring the mozzarella is completely covered. Cook under the grill.
3. Meanwhile fry off onion and garlic.
4. Pour in tomato passata and add seasoning.
5. Add in meatballs and simmer until thickened.

Homemade Meatball Subs

When it comes to the subs themselves, I prefer to do single portions, rather than one big giant one and cut it into pieces.

You’re looking to get 5x approximately 6″ sized baguettes, preferably white bread and not too crusty. The firmer the bread you start off with, the more likely it’s going to come out hard and chewy on the other side. If you can get your hands on a nice soft baguette then that’s perfect.

From this you’ll get 4 meatballs per sub.

How to make Meatball Subs (quick summary)

1. Slice your baguette open (not all the way through), drizzle with olive oil and lightly toast under the grill.
2. Spread a few tbsp of sauce on one side.
3. Add 4 meatballs.
4. Top with cheese and grill until gooey.

It really is that easy!

What cheese is best on meatball sub?

These subs actually have 3 cheeses in them. One in the meat itself (parmesan), one in the centre (mozzarella) and one on top. For the third one, I usually go for a nice sharp cheddar.

What are good toppings for a meatball sub?

I usually keep it classic and stick with just the cheese. However jalapeños, red onion, shredded lettuce and olive all go great on top after they’re grilled. Completely work to preference though!

Do I have to toast the bun?

Nope! Just like in subway, it’s completely optional. BUT grilled cheese > slightly melted cheese (IMO). Up to you though 🙂

Can I just use half a baguette?

You sure can! I just love extra carbs so creating a sandwich is more my jam. But you can just use one slice and have an open-style sub kinda thing.

Can I make the meatballs ahead of time?

Sure! I recommend making them and cooking in the sauce, then allowing to cool and store in the fridge (3-4days) or freezer (1month). Thaw in fridge overnight and then reheat on the stove until piping hot.

Can I use store bought meatballs?

I mean, I HIGHLY recommend homemade (come on, cheese stuffed homemade meatballs?!?!), but, you can use store bought if you wish 🙂

What to serve with meatball subs?

I usually serve as they are, but if you want to make it more of a meal consider adding a side salad or oven baked wedges or crispy french fries!

Instructions 

Meatballs

• Soak bread in milk, onion, garlic and Worcestershire sauce & mush with fork. Stir in parsley, parmesan, oregano, egg & seasoning. Gently work in your pork & beef (don’t over mix or they will end up tough), then form 20 meatballs with mozzarella in the centre. Lightly spray with oil then pop under the grill for 10mins or until golden on the outside. Flip once half way and shake about to evenly cook. Timings will vary based on power of grill/how close they are to it, so just be vigilant.

Sauce

• Fry onion/garlic until soft then pour in Passata. Stir in seasoning and leave to simmer for 10-15mins. Add meatballs (with some pan juices) and simmer for another 5-10mins, or until the sauce thickens.

Subs

• Spread a couple tbsp of sauce on one side of your baguette, top with 4 meatballs each, then cheese & finish with a few small basil leaves. Grill/Broil for a few mins until gooey. Serve as they are, or with a side salad or wedges/fries

Notes

a) Perfect meatballs - For a more in depth post about how to get awesome homemade meatballs, check out my soft and juicy meatballs!

b) Cherry Mozzarella Balls - You'll get these at most grocery stores. They could also be called mini bocconcini balls. If you can't get your hands on either then just buy a ball of mozzarella and cut into pieces about the same size as a small cherry tomato.

c) Tomato Passata - In the US I believe this is called Tomato Puree (i.e just pureed tomatoes). NOT Tomato paste, which is much more concentrated, so make sure you don't use that.

d) What Baguette to use? - I usually use white baguettes around 6" in size. Also make sure you use one that's on the softer side. If you start with a baguette that's firm and crusty, it's going to come out hard and chewy once they're cooked.

e) Toasted Baguettes - To lightly toast them just drizzle with olive oil and pop under the grill for a few mins. Make sure they're only lightly toasted though, otherwise they'll come out burnt when you've grilled the cheese.

f) Make Ahead Meatballs - I recommend making the meatballs completely (in the sauce) then cooling, tightly covering and storing in the fridge (3-4days, reheat on stove) or in the freezer (1month, thaw in fridge then reheat on stove). 

g) Calories - per sub, using 1 tsp olive oil for frying and using white 6" baguettes.
