How To Make Italian Meatball Sub Subway Copycat Recipe

MAKE THE ITALIAN MEATBALLS WITH MARINARA

If you have leftover meatballs you can skip the process of making meatballs, otherwise here it is!

STEP 1: Combine the Italian Meatball Ingredients

Place all of the meatball ingredients in a large sized mixing bowl, or in a stand mixer bowl if using.

instant pot italian meatballs and sauce subway copycat recipe step 3

Use the paddle to combine the ingredients thoroughly into a uniform mix. Once complete, safely unlock and lift the mixer head and remove the mixer bowl.

If you don’t have a stand mixer, you can combine all ingredients in a bowl with a spatula or large spoon.

STEP 2: Form Italian Meatball Mix into Balls

Use an eighth cup measuring cup to scoop up the mix for each ball. Roll each by hand. TIP: Wet hands with a little water to avoid stickiness when rolling.

STEP 3: Brown Italian Meatballs in Batches

In SAUTE mode, melt butter and carefully place half of the meatballs in the Instant Pot. Brown the Italian meatballs for a minute or two on each side.

Remove to a plate taking care to not break them and repeat the browning process with the remaining half. Remove second batch of browned meatballs from the Instant Pot.

STEP 4: Add Water and Deglaze the Pot

Add a half cup of water to the Instant Pot and use a spatula to scrape the bottom of the pot to ensure there are no stuck bits on the bottom. This is to ensure that there won’t be a burn notice during the cook cycle.

Position an Instant Pot trivet (metal or silicon) into the pot, over top of the water.

Add browned meatballs on top of the trivet.

Next, pour marinara sauce over top of the Italian meatballs while trying to keep as much of it on top of the meatballs as possible. It’s ok if some sauce goes to the bottom, but we try to keep it to a minimum to avoid a possible burn notification.

Secure the lid on the Instant Pot and move the pressure valve to SEALING. Pressure cook on HIGH at Normal temperature for seven minutes. Quick release the pressure when completed, by moving the pressure valve to VENTING.

When the pressure has been released and it is safe to do so, carefully remove the lid off of the Instant Pot.

Remove the trivet while gently angling it to one side so that the meatballs fall into the marinara sauce (take care to avoid any splashes – it’s hot!). Mix the meatballs and marinara sauce and allow to cool a bit.

Crockpot or Slow Cooker Method

If you have the time and you’d like to make these Italian meatballs in a slow cooker you can follow the recipe up to the point of forming the meatballs.

Once you have your meatballs shaped, instead of an Instant Pot, you’ll brown them in a large skillet on the stovetop. You’ll still need to brown the meatballs in two batches and remove them to a plate as you go. Omit the water in the recipe as that is for bringing the Instant Pot to pressure and you won’t need it for your slow cooker.

From there, add marinara sauce to the crockpot and then nestle the meatballs into the sauce. Set the slow cooker for 4 hours on HIGH or 8 hours on low.

ASSEMBLE THE ITALIAN MEATBALL MARINARA SUBS

STEP 1: Place Meatballs and Marinara on Sub

Preheat oven to 400℉. Cut an opening lengthwise along the sub without cutting all the way through the back.

Arrange meatballs along the open sub bread. Depending on the size of meatballs and length of bread, you may need more or fewer meatballs. Spoon some marinara sauce over top of the meatballs.

Place in preheated oven and bake until the cheese is melted and bubbling.

What To Serve With Italian Meatball Sub Subway Copycat Recipe

Italian meatball subs are fabulous with salad or soup. An Italian style house salad is perfect, as is a simple asparagus cucumber tomato salad.

You can add Italian style appetizers like spinach artichoke dip or a bowl of marinated olives.

If you’d like to reduce the carbs, you can make the Subway style meatballs into a meatball pita pizza. You still get all of the flavor!

Storage Tips for Italian Meatball Sub Subway Copycat Recipe

Although you can store the meatball sub leftovers in the fridge for up to three days, they are best enjoyed fresh. To ensure the bread doesn’t change too much in texture, try to consume them within a day or two.

You can reheat them in the oven in a similar manner. Just place the meatball subs on a parchment lined baking sheet and into the preheated oven until the cheese melts.

You’ll Also Love

At our house we rotate between Instant Pot Italian meatballs and Instant Pot Swedish meatballs. If we didn’t, we probably wouldn’t get along very well, given our heritages (Just kidding). Although, lucky for us, the recipes are both top notch!

You’ll love this hearty Swedish meatball sandwich (kottbullemacka) made with Instant Pot IKEA Swedish Meatballs and Swedish creamy pickled beet salad (rödbetssallad).

It’s a perfect sandwich for Swedish meatball leftovers on Swedish style rye bread. The pickled beet salad is super easy to make, with a can or jar of pickled beets, just dice them and add some quick ingredients!

  • Press Saute on the Instant Pot. When the display reads HOT, place half of the meatballs in the inner pot. Brown the meatballs for a few minutes before carefully flipping them over with a spatula.
