Spaghetti Grilled Cheese might sound wild but it is pure comfort food at my house Spaghetti noodles are tossed in a homemade meat sauce spread between buttered bread slices loaded with mozzarella then griddled until everything is gooey and golden If you love carbs on carbs this twist is made for you
I started making these sandwiches on Friday movie nights when there was leftover spaghetti now my family asks for them even when there are no leftovers to use
Ingredients
- Olive oil: for sautéing the onion and garlic choose extra virgin for best flavor
- Onion: peeled and diced sweet yellow onions work especially well here
- Garlic: peeled and crushed fresh garlic gives a pungent aroma avoid pre-minced jars
- Ground beef: lean is best to keep the sauce from being greasy
- Crushed tomatoes: look for no salt added so you can control seasoning
- Salt: enhances all the flavors use sea salt if possible
- Water: for adjusting sauce thickness filtered is best for pure flavor
- Fresh basil leaves: brightens everything use just-picked if you have it
- Freshly grated Parmesan: nutty depth always grate just before using
- Dried spaghetti: classic pasta shape that holds sauce well check the package for a firm al dente time
- Unsalted butter: for the garlic spread use high quality for a rich flavor
- Italian seasoning: a mix of herbs that creates an instant flavor shortcut
- Garlic powder: for extra savory punch choose one without added fillers
- Mozzarella: thin slices melt best and give that signature stretch

My favorite part of this recipe is seeing the look on my child’s face when they bite in and realize there is pasta inside the sandwich It reminds me of making late night grilled cheese as a kid but with a playful Italian twist
Storage Tips
Let sandwiches cool completely before wrapping them in foil or wax paper and placing them in a freezer bag They stay fresh in the fridge for up to two days or in the freezer for up to a month To reheat crisp them in the oven at 350 degrees until piping hot and the bread is toasty again

Ingredient Substitutions
Try ground turkey or Italian sausage instead of beef for a lighter or zestier filling If you do not have fresh basil use a small pinch of dried basil in the sauce Dairy free mozzarella works if you need this to be lactose free Any sturdy sandwich bread works as long as it does not get soggy

Recipe FAQs
- → How do I keep the spaghetti from falling out?
Chill the sauced spaghetti in a flat layer, then cut into slabs. This helps the noodles hold together inside the sandwich.
- → What's the best bread to use?
Choose sturdy bread like sourdough or thick sandwich slices, which can handle moist fillings and grill to crispy perfection.
- → Can I substitute the meat sauce?
Absolutely! Try marinara for a vegetarian version, or use your favorite prepared tomato sauce for convenience.
- → How do I prevent sogginess?
Melt butter with seasonings and brush on the outside; avoid overfilling with sauce, and grill over medium-low heat for even browning.
- → What cheese works best here?
Thin slices of mozzarella melt beautifully, but provolone or fontina make tasty alternatives for a twist on flavor.
- → Is this sandwich freezer-friendly?
It's best enjoyed fresh off the griddle. Assembled sandwiches can be refrigerated briefly before grilling but don't freeze well once cooked.
