RECIPE TIPS

  • If desired, make your own marinara sauce using crushed tomatoes, onions, garlic, and your favorite Italian herbs.¬†
  • Roast the minced garlic in a bit of olive oil before adding it to the slow cooker. This will mellow out the sharpness and infuse the sauce with a rich, aromatic taste.
  • Opt for high-quality frozen Italian-style meatballs with natural ingredients and no preservatives for the best taste and texture. Alternatively, you can make your own meatballs using a mix of ground beef, pork, breadcrumbs, eggs, and seasonings.
  • Stir the meatballs occasionally during the cooking process to ensure even coating with the marinara sauce and to prevent sticking to the bottom of the slow cooker.
  • Before assembling the subs, lightly toast the hoagie rolls in the oven to add a satisfying crunch to each bite and prevent them from becoming soggy.
  • Don't forget the final touch of grated Parmesan cheese as a garnish. It's a small addition that makes a big difference, adding a burst of umami flavor and a lovely visual appeal to the finished meatball subs.

STORING & FREEZING

Storing: Allow the dish to cool completely and then transfer to an airtight container. Store the container in the refrigerator for up to 3-4 days. To keep the subs fresh, it's best to store the meatballs and sauce separately from the hoagie rolls and cheese.

Freezing: Only the meatballs and sauce mixture is best for freezing. Allow it to cool before transferring to an airtight container or freezer-safe bag to freeze for up to 3 months. Thaw overnight in the fridge before reheating in the crock pot, stovetop, or the microwave. Assemble sandwiches when the mixture is warmed through. 

FAQ

Why do my meatballs fall apart in the slow cooker?

Meatballs can sometimes fall apart in the slow cooker if they are too lean or if they are not properly bound together. While you can use homemade meatballs, frozen meatballs stay together better. 


Can you leave meatballs in the crockpot all day?

While slow cooking is generally safe, it's best to avoid leaving meatballs in the crockpot for extended periods as they could break down too much and lose their shape. 

What kind of sauce is on meatball subs at Subway?

At Subway, their meatball subs are typically served with a marinara sauce that has a tangy tomato base and is seasoned with Italian herbs, garlic, and spices along with sweetness. To achieve this at home, purchase a marinara sauce that has herbs and spices along with a higher sugar content.
