Stuffed Spaghetti Subs
This was inspired by my spaghetti alla bolognese recipe on this site and pairs well with this amazing pasta salad recipe.
It only takes a handful of ingredients to make these easy spaghetti subs.
- sub buns
- spaghetti noodles
- frozen meatballs
- spaghetti sauce
- mozzarella cheese
- parmesan cheese for serving, if desired
- garlic butter, if desired
See the recipe card below for exact quantities.
Making this recipe is an incredibly easy affair. It only takes a few steps and a few minutes.
Step 1: Cook the Noodles and Make the Meatballs
Cook the noodles according to the package directions for al dente, then drain them and dump them into a large bowl. Prepare the meatballs according to the package directions and set them aside.
Step 2: Add the Sauce
Add the spaghetti sauce to the cooked spaghetti and meatballs. Toss with tongs until fully coated.
Step 3: Toast the Buns, If Desired
Split the buns in half and cover with garlic butter.
Add ¼ cup of mozzarella cheese to each side or more. Place them on a rimmed baking sheet.
Place them under a preheated broiler until the cheese is melted with a few golden spots. Remove them from the oven and place them on a plate.
Step 4: Make the Subs
Using tongs, transfer ¼ of the spaghetti onto each sub and add 4 meatballs. Sprinkle with mozzarella or parmesan cheese.
Broil until cheese is melted. Serve immediately.
Hint: Keep a close eye on your subs when toasting them so they don't burn.
