Begin by softening ½ cup of butter in a small bowl, then mix in 3 cloves of minced garlic and 1 tablespoon of finely chopped parsley. Stir well until fully combined. Set aside to allow the flavors to meld.

Take 4 sturdy garlic bread rolls, and carefully hollow them out using a sharp knife. Leave a bit of bread on the bottom and sides to hold the filling without leaking.

Preheat your oven to 375°F (190°C). Generously coat the insides of the hollowed rolls with the prepared garlic butter. Place them on a baking sheet and bake for about 10-12 minutes, or until they are golden and crispy.

While the rolls are toasting, bring a large pot of salted water to a boil. Add 8 ounces of spaghetti and cook according to package instructions, until al dente. Drain the pasta and return to the pot. Pour in 1 cup of marinara sauce and stir well.

Spoon the cheesy spaghetti mix generously into each roll, making sure they are well-filled but not overflowing. Top each filled roll with a sprinkle of freshly grated Parmesan cheese.

Return the assembled garlic bread bowls to the oven and bake for an additional 5-7 minutes, until the cheese is melted and bubbly.

Carefully remove your Cheesy Spaghetti in Garlic Bread Bowls from the oven and serve immediately while the rolls are crispy and the filling is gooey.
