🔹 Step 1: Make the Spaghetti
Boil pasta: Cook spaghetti according to package directions until al dente. Drain and set aside.

Cook sauce: In a large skillet, heat olive oil over medium heat. Add onion and garlic; sauté until fragrant.

Add meat: Brown the ground beef/sausage until fully cooked. Drain excess fat if needed.

Simmer: Stir in marinara sauce and Italian seasoning. Simmer for 10–15 minutes. Season with salt, pepper, and optional red pepper flakes.

Combine: Toss the cooked spaghetti into the sauce. Mix until fully coated.

🔹 Step 2: Make the Stuffed Garlic Bread
Preheat oven: 375°F (190°C).

Prepare bread: Slice the bread into sections (about 1 inch apart) without cutting all the way through the bottom.

Stuff: Place mozzarella inside each slit. You can also sprinkle in some extra garlic or herbs.

Garlic butter: Mix melted butter, garlic, and parsley. Brush generously over the top and inside the slits.

Bake: Wrap in foil and bake for 15–20 minutes. Uncover and bake 5 more minutes to brown and crisp the top.

Serve warm with a sprinkle of Parmesan on top if desired.

🍽 Serving Suggestion
Plate the spaghetti with a generous heap of sauce.

Slice and serve the gooey, golden mozzarella garlic bread on the side.

Add a fresh side salad or glass of red wine for a complete meal.
