What Do You Put On A Meatball Sub (Toppings)?
Onions- Finely chopped, or or sauted or grilled.
Cheese- Add freshly shredded mozzarella, parmesan, provolone, or even Swiss.
Sun-dried tomatoes- These will add a nice flavor and texture.
Gardinera- Hot or mild, whichever you prefer.
Spinach- Fresh baby or regular spinach.
Basil- Use fresh basil leaves, whole or shredded.
Bacon- Crumbled bacon adds a lovely texture and saltiness.
Pepperoncini peppers- For a slightly spicy kick.
Variations For Homemade Meatball Subs
Use red sauce- In place of brown gravy, use Homemade Marinara Sauce or your favorite tomato sauce.
Use non-beef meatballs- Try ground pork, turkey, or chicken meatballs instead.
Open-faced subs- Serve the sub open-faced for an alternate presentation.
Add other vegetables- Such as artichokes, eggplant, or zucchini. The possibilities are endless!
Use leftovers as a pasta topping- Serve the meatballs and veggies atop your favorite pasta.
Ranch meatball subs- Add some dry ranch powder for even more flavor.
Make it spicy- Add red chili flakes for a little heat, or add jalapenos for more spice.
Use other mushrooms- Such as shitake, portobello, white button, or crimini.
Tips And Techniques
Use hoagie rolls or other thick bread/buns- Because they won't fall apart when filled and they also won't become soggy with the gravy.
How to release pressure in Instant Pot? When the cooking time is finished, turn the knob to do a quick release.
How to thicken gravy? Continue cooking uncovered on the "Saute" mode, while mixing, until excess liquid is released to your desired consistency.
Do I need to add water to the Instant Pot? Yes, initially the recipe calls for 1 cup of water so that enough pressure can be created in order to cook the meatballs and vegetables properly.
Use low-sodium gravy packet- Because this ensures that the meal is not too salty.
Can I use fresh homemade meatballs instead of frozen? I use frozen meatballs in order to save time and for convenience purposes, but yes, you can use homemade fresh meatballs too.
Serve immediately- To prevent the subs from becoming too soggy.
Storage
Refrigerate- In a sealed container for up to 3 days.
Freeze- I recommend freezing the meatballs and bread separately in sealed containers and assembling when you are ready to serve.
Reheat- From thawed in the microwave or in the oven.
