Ingredients You’ll Need

- 2 slices of bread (sourdough or Italian work best)

- 1 tbsp grated Parmesan cheese
- 2 cloves garlic, minced
- ½ tsp fresh basil, chopped
- Butter for spreading
How to Make Spaghetti Grilled Cheese Sandwich
Creating this Ultimate Spaghetti Grilled Cheese Sandwich requires a bit of technique to ensure the pasta stays contained while achieving that perfect golden crust. The key is proper layering and temperature control to melt the cheese thoroughly while crisping the bread to perfection.
Step-by-Step Instructions
Step 1: Prepare Your Ingredients Start by ensuring your cooked spaghetti is at room temperature or slightly warm. If using leftover spaghetti, gently reheat it in the microwave for 30 seconds. Mix the minced garlic and fresh basil into the spaghetti, ensuring even distribution of flavors throughout.
Step 2: Butter the Bread Generously butter one side of each bread slice. This will become the exterior of your sandwich and is crucial for achieving that golden, crispy crust that makes the Ultimate Spaghetti Grilled Cheese Sandwich so special.
Step 3: Layer the Filling Place one slice of bread butter-side down in a cold pan. Sprinkle half of the mozzarella cheese evenly across the bread, creating a base layer that will help hold everything together. Carefully layer the seasoned spaghetti on top, keeping it slightly away from the edges to prevent spillage.
Step 4: Add Final Layers Sprinkle the remaining mozzarella and all of the Parmesan cheese over the spaghetti. The combination of these cheeses will create the perfect melty texture that defines the Ultimate Spaghetti Grilled Cheese Sandwich. Top with the second slice of bread, butter-side up.
Step 5: Cook the Sandwich Heat your pan over medium-low heat. This lower temperature is essential for giving the cheese time to melt completely before the bread burns. Cook for 4-5 minutes on the first side until golden brown, then carefully flip using a large spatula. Cook for another 3-4 minutes until the second side is golden and the cheese is fully melted.
Step 6: Rest and Serve Remove from heat and let the sandwich rest for 2-3 minutes before cutting. This allows the cheese to set slightly, making it easier to cut and preventing the filling from spilling out.
Helpful Tips
Use day-old bread for better structure and less sogginess. Fresh bread can become too soft when it absorbs moisture from the marinara sauce, while slightly stale bread maintains its integrity better.
Press down gently with your spatula while cooking to help the ingredients meld together, but avoid pressing too hard as this can cause the filling to squeeze out the sides.
Keep the heat at medium-low throughout the cooking process. Higher temperatures will burn the bread before the cheese has time to melt properly, resulting in an unevenly cooked Ultimate Spaghetti Grilled Cheese Sandwich.
If your pan is too small, consider making open-faced versions instead, cooking them under the broiler for 2-3 minutes until the cheese is bubbly and golden.

Notes

For the best results with your Ultimate Spaghetti Grilled Cheese Sandwich, use spaghetti that’s not overly saucy. Excess liquid can make the bread soggy and cause the sandwich to fall apart. If your leftover spaghetti seems too wet, drain it slightly before using.
Experiment with different cheese combinations such as adding sharp cheddar or provolone for more complex flavors. You can also incorporate other Italian herbs like oregano or thyme for additional depth.
This recipe works beautifully with other pasta shapes too. Penne, rigatoni, or even leftover mac and cheese can be substituted for equally delicious results.
Frequently Asked Questions
Can I make this sandwich ahead of time? While the Ultimate Spaghetti Grilled Cheese Sandwich is best served immediately, you can prepare the components ahead of time. Store the seasoned spaghetti in the refrigerator for up to 3 days and assemble the sandwich just before cooking.
What if I don’t have leftover spaghetti? You can easily cook fresh spaghetti specifically for this recipe. Use about 2-3 ounces of dried pasta, cook according to package directions, and toss with your favorite marinara sauce.
Can I bake this instead of pan-frying? Yes, you can bake the Ultimate Spaghetti Grilled Cheese Sandwich at 400°F for about 10-12 minutes, flipping halfway through. However, pan-frying gives better control over the browning process.
How do I prevent the filling from falling out? Keep the spaghetti away from the edges of the bread and don’t overfill. Press gently while cooking and allow the sandwich to rest before cutting.
Storage Instructions
The Ultimate Spaghetti Grilled Cheese Sandwich is best enjoyed fresh and hot. However, if you have leftovers, wrap them tightly in aluminum foil and store in the refrigerator for up to 2 days.
To reheat, place the wrapped sandwich in a 350°F oven for 10-12 minutes, or unwrap and reheat in a skillet over low heat for 2-3 minutes per side. Avoid microwaving as this will make the bread soggy and won’t restore the crispy texture that makes this sandwich special.
For longer storage, you can freeze the assembled but uncooked sandwich for up to 1 month. Wrap tightly in plastic wrap and aluminum foil. Cook directly from frozen, adding an extra 2-3 minutes to each side.
