Ingredients

Gathering your ingredients is half the fun! Here’s what you’ll need:

• 1 pound ground beef: You can also use a mix of beef and pork if you like a little extra richness!
• ¼ cup breadcrumbs: Panko breadcrumbs give a nice texture, but regular breadcrumbs work great too.
• 1 egg: This is our binder to keep those meatballs nice and round.
• 2 tablespoons grated Parmesan cheese: For that salty, nutty flavor. Don’t skip this!
• 1 teaspoon garlic powder: Because what’s a savory dish without garlic?
• 1 teaspoon onion powder: Adds a subtle sweetness and depth.
• Salt and pepper, to taste: Season generously!
• 3 cups marinara sauce: Your favorite jarred sauce is perfect here. Feel free to use a homemade one if you have it!
• 6 sub rolls: Look for soft, fresh rolls that will soak up all that delicious sauce.
• 1½ cups shredded mozzarella cheese: The melty, gooey topping dreams are made of!
• Extra Parmesan cheese, for topping: A little extra sprinkle before serving adds a lovely finish.

How to Make It

Let’s get cooking! This is where the magic happens with minimal effort.

1. Meatball Time: Grab a medium-sized bowl. Toss in your ground beef, breadcrumbs, egg, 2 tablespoons of grated Parmesan cheese, garlic powder, onion powder, salt, and pepper. Now, get your hands in there and mix everything together until it’s just combined. Don’t overmix, or your meatballs can get tough!
2. Roll ‘Em Up: Once everything is nicely mixed, roll the beef mixture into about 1-inch meatballs. You should get around 18-24 meatballs, depending on how big you make them.
3. Into the Crockpot: Gently place your freshly rolled meatballs into your crockpot.
4. Sauce Bath: Pour that lovely marinara sauce right over the top of the meatballs. Make sure they’re mostly submerged for even cooking.
5. Low and Slow (or Fast!): Now, cover your crockpot and let it do its thing. Cook on the low setting for 3-4 hours, or on the high setting for 2-3 hours. You’ll know they’re ready when the meatballs are cooked through and tender.
6. Prep the Buns: While those meatballs are getting perfectly cooked, slice your sub rolls lengthwise. You can leave them hinged or separate them completely – whatever you prefer!
7. Assemble Your Masterpiece: Once the meatballs are done, carefully spoon the meatballs and plenty of that delicious marinara sauce into each sub roll. Don’t be shy with the sauce!
8. Cheesy Goodness: Sprinkle a generous amount of shredded mozzarella cheese over the top of the meatballs in each roll.
9. Melt Away: Now, here’s a little trick for super melty cheese. You can either carefully place the filled subs back into the empty crockpot (if there’s room and you don’t mind a little mess!) or transfer them to a separate oven-safe dish. Cover them up.
10. Get Your Melt On: Heat until the cheese is beautifully melted and bubbly. If you put them back in the crockpot, just a few minutes on high should do the trick. If you used an oven-safe dish, pop it under the broiler for a minute or two, or bake at around 350°F (175°C) for about 5-10 minutes, watching carefully so they don’t burn!
11. Finishing Touch: Before serving, sprinkle a little extra Parmesan cheese over the top. It adds that perfect salty finish!

Substitutions & Additions

The beauty of this recipe is how adaptable it is! Feel free to make it your own.

• Meat: If you’re not a fan of ground beef, try ground turkey, chicken, or even Italian sausage for a bolder flavor.
• Sauce: Feel free to experiment with different sauces! A vodka sauce or a spicy arrabbiata would be delicious.
• Cheese: Provolone is a fantastic alternative or addition to mozzarella. A sprinkle of grated Pecorino Romano would also be lovely.
• Spice: Add a pinch of red pepper flakes to the meatball mixture or the marinara sauce for a little kick.
• Veggies: Sautéed onions and bell peppers can be added to the crockpot with the sauce for extra flavor and texture.

Tips for Success

A few little pointers to make your Crockpot Meatball Subs absolutely perfect:

• Don’t Overmix: I mentioned this before, but it’s worth repeating! Overmixing the ground beef will result in tougher meatballs. Mix until just combined.
• Even Sizing: Try to make your meatballs as close to the same size as possible so they cook evenly.
• Prepping Ahead: You can make the meatballs and store them in the refrigerator for up to 24 hours before cooking. You can also cook the meatballs and sauce in the crockpot the day before and gently reheat before assembling the subs.
• Melting the Cheese: If you’re worried about the rolls getting soggy from the sauce when you melt the cheese, you can lightly toast the inside of the rolls before filling them.

How to Store It

Leftovers are a good thing! If, by some miracle, you have any:

• Refrigeration: Store any leftover meatball subs (or just the meatballs and sauce) in an airtight container in the refrigerator for up to 3 days.
• Reheating: For best results, reheat the meatballs and sauce gently on the stovetop or in the microwave. If reheating the assembled subs, you can warm them in a covered oven-safe dish at 350°F (175°C) until heated through.

FAQs

Got questions? I’ve got answers!

Q: Can I make the meatballs ahead of time and freeze them?
A: Absolutely! You can freeze uncooked meatballs on a baking sheet until firm, then transfer them to a freezer-safe bag for up to 3 months. Cook them directly from frozen in the crockpot, adding a little extra cooking time.

Q: My crockpot tends to cook hot, can I adjust the cooking time?
A: Yes! If your crockpot runs hot, you might want to check your meatballs at the lower end of the time range (2 hours on high, 3 hours on low) to ensure they don’t overcook.

Q: What kind of sub rolls are best?
A: Soft, fresh sub rolls are ideal. Hoagie rolls or even good quality French bread rolls would also work wonderfully!

Q: Can I make these vegetarian?
A: While this recipe is specifically for meatball subs, you could adapt it by using vegetarian “meatballs” and your favorite marinara sauce for a meat-free option!
