    I absolutely love these subs because they're a classic spaghetti dinner combined into one sandwich. They're literally everything we love about spaghetti dinners.

    Adults and kids love this easy dinner.

    Stuffed Spaghetti Subs

    This was inspired by my spaghetti alla bolognese recipe on this site and pairs well with this amazing pasta salad recipe.

    Ingredients

    It only takes a handful of ingredients to make these easy spaghetti subs.

    Overhead photo of all the ingredients.
    • 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.

    Instructions

    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 and 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 and serve immediately.

    Hint: Keep a close eye on your subs when toasting them so they don't burn.

    Substitutions

    Don't have the correct ingredients on hand or want to change something up? Here are some helpful tips for you to change this Stuffed Spaghetti Subs recipe.

    • Sub Buns - Use hoagie, hot dog, sausage, hamburger or your favorite hard or soft rolls instead
    • Toast or Not to Toast - I leave the decision up to you but I prefer to toast my buns and melt cheese on top of each side under the broiler. My husband and son prefer this sandwich exactly as shown
    • Spaghetti Noodles - Use linguini, fettuccini (tagliatelle), angel hair (capellini), vermacelli, bucatini, rotini, penne or your favorite pasta
    • Vegetarian - Use a plant-based meatball will make this dish this vegetarian.
    • Spaghetti Sauce - Use your favorite brand or variety, even alfredo sauces work beautifully too
    • Cheese - No mozzarella? No worries. Use provolone, burrata, scamorza, white cheddar, gouda, parmesan or your favorite cheese instead
    • Garlic Butter - Use regular butter instead if you're using butter at all

    Variations

    Want to personalize this Spaghetti Stuffed Subs recipe? Here are some of my tried and true tips for changing up this recipe.

    • Spicy - Add chili pepper flakes, use diced or chopped cayenne, poblano, tabasco, or your favorite hot peppers to add heat to this sandwich
    • Seasoning - Add some extra Italian seasoning, garlic powder or your favorites to your sauce to add more flavor
    • Loaded - Add sauteed onions, sweet peppers, shredded carrots, celery and mushrooms
    • Meat Lovers - Add chopped ham, cooked sausage, cooked bacon, cooked ground beef or any other meat you want to include
    • Canned Spaghetti and Meatballs - To make these the fastest sandwiches on earth to make simply heat a can of spaghetti and meatballs and add to bun
    • Mini Italian Bread or French Bread Loaf - make your own bread boat or spaghetti boat just the way you want it
    • Garlic Bread - Create a spaghetti stuffed garlic bread. With or without cheese you won't be disappointed.

    Equipment

    You'll only need a few basic pieces of kitchen equipment to make this recipe.

    • rimmed baking sheet
    • saucepan
    • large skillet
    • serrated bread knife
    • Cheese grater
    • Tongs

    Storage

    Store the spaghetti and meatballs in the refrigerator in an air-tight container for up to 3 days. Reheat and place on buns when ready to serve again.

    Tips

    This is an incredibly easy recipe. It's so easy, in fact, I only have 2 tips.

    • Shred your own cheese, as store-bought shredded cheese includes additives and your cheese won't melt as it should
    • Always keep an eye on your buns when toasting so they don't burn.
