Boil the Pasta: Bring 4 quarts of salted water to a rolling boil. Add 2 tablespoons of salt. Once boiling, add spaghetti, cooking for 8-10 minutes until al dente. Drain through a colander, reserving 1 cup of pasta water.

Prepare the Garlic Sauce: Heat 2 tablespoons of olive oil in a large skillet over medium heat. Add 4 minced garlic cloves and a pinch of red pepper flakes, sautéing for 1-2 minutes until fragrant.

Toss the Spaghetti: Add the drained spaghetti to the skillet. Gradually pour in the reserved pasta water, stirring gently. Allow to cook for additional 1-2 minutes, letting it absorb the garlic oil.

Add Fresh Ingredients: Stir in chopped parsley and ½ cup of grated Parmesan cheese. Season with salt and pepper to taste.

Make the Garlic Butter: Combine ½ cup of softened unsalted butter, 2 minced garlic cloves, 2 tablespoons of chopped parsley, ¼ cup of Parmesan, and a sprinkle of garlic powder in a bowl. Mix until well-blended.

Prepare the Bread: Slice a loaf of Italian bread in half lengthwise. Spread the garlic butter mixture generously over both halves.

Bake the Garlic Bread: Preheat oven to 375°F (190°C). Bake garlic bread on a baking sheet for 10-12 minutes, or until golden brown and crisp.

Serve & Enjoy: Plate spaghetti and sprinkle with extra Parmesan and parsley. Serve alongside warm garlic bread.
