Meatball Sub Grilled Cheese Sandwiches

I’ve included some videos below for those who prefer to watch rather than read.

Meatball sub grilled cheese sandwiches combine two comfort food favorites into one tasty meal. You take the classic meatball sub and turn it into a crispy, cheesy grilled sandwich. To make this sandwich, layer meatballs, marinara sauce, and Italian cheeses between buttered bread slices, then grill until golden brown.

This fun twist on a traditional sub is easy to make at home. You can use homemade or store-bought meatballs and sauce. The melty cheese and toasted bread add great texture. It’s a filling sandwich that’s perfect for lunch or dinner.

Exact Ingredients (+ Possible Substitutes)

Here’s what you’ll need to make meatball sub grilled cheese sandwiches:

• Ground beef (80/20 lean)
• Bread crumbs
• Grated Parmesan cheese
• Eggs
• Garlic powder
• Salt and pepper
• Hoagie rolls or thick sliced bread
• Tomato sauce
• Mozzarella cheese
• Butter

Don’t have some ingredients? Try these swaps:

• Ground turkey instead of beef for a lighter option
• Rolled oats in place of breadcrumbs
• Any melty cheese can replace mozzarella

For the sauce, use jarred marinara if you’re short on time. Fresh basil adds great flavor, but dried works too.

Want to spice things up? Add red pepper flakes to your meatballs or sauce. For extra indulgence, sprinkle some grated Parmesan on top of your sandwich before grilling.

Remember, the key to tasty meatballs is not overworking the meat. Mix just until combined for the best texture.

Instructions

Grab two slices of bread and butter one side of each. Place one slice butter-side down in a pan.

Add a layer of provolone cheese on the bread. Spread some marinara sauce over the cheese.

Place sliced meatballs on top of the sauce. Sprinkle fresh basil leaves over the meatballs.

Add a layer of mozzarella cheese on top of the basil and meatballs.

Put the second slice of bread on top, butter-side up.

Cook the sandwich over medium heat until golden brown on the bottom, about 3-4 minutes.

Carefully flip the sandwich and cook the other side until golden and the cheese is melted.

Remove from heat and let cool for a minute before slicing. Enjoy your meatball sub grilled cheese!
