What To Serve With Meatball Sandwich?

The sandwich will pair so nicely with a warm bowl of vegetable based soup. Serve it with Tomato Basil Soup (One Pot), Roasted Red Pepper Soup (One Pot), or Carrot Ginger Soup (One Pot).

Salads are also a light pairing to compliment this hearty sandwich. This Easy Pear Salad (One Bowl), Easy Kale Salad (One Pot), or Christmas Salad (One Bowl).

Roasted Vegetables are a great addition to this meal such as Oven Roasted Vegetables (One Pan), Oven Roasted Carrots (One Pan), or Oven Roasted Broccoli (One Pan).

What Do You Put On A Meatball Sub (Toppings)?

  • Onions– Finely chopped, or grilled.
  • Cheese– Add 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– Add fresh basil leaves whole or shredded.
  • Bacon– Crumble bacon top for some texture and saltiness.
  • Pepperoncini– For a spicy kick.

Variations For Homemade Meatball Subs

Use red sauce– In place of brown gravy, use a marinara or tomato sauce.

Use non-beef meatballs– Use 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.

Use leftovers as a pasta topping– Serve the meatballs and veggies atop your favorite pasta.

Ranch meatball subs– Add a dry ranch packet to add 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– They won’t fall apart when filled.

How to release pressure in Instant Pot?– When the timer is finished, turn the knob to quick release.

How to thicken gravy?– Once meatballs and vegetables are mixed back in with the gravy, continue cooking uncovered (while gently mixing often) until gravy thickens 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– This ensures that the recipe 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 you can use homemade fresh meatballs if you prefer.

Storage

Refrigerate– In a sealed container for up to 3 days.

Freeze– I recommend freezing the meatballs and bread separately in a freezer safe bag or container for best results.

Reheat– From thawed in the microwave or in the oven.
