Fill a large pot with 7 cups water and add 1 pinch salt; bring to a rolling boil over high heat.
Once boiling, add 8 ounces wide egg noodles and stir gently to prevent sticking; cook 6–8 minutes until al dente.
While noodles cook, heat a large skillet over medium heat and melt 4 tablespoons unsalted butter.
Add 4 garlic cloves (minced) to the melted butter and cook 1–2 minutes, stirring constantly, until fragrant and lightly golden.
Drain the noodles in a colander without rinsing and immediately transfer them to the skillet with garlic butter.
Toss noodles gently to coat evenly in the garlic butter.
Sprinkle in 0.25 cup grated Parmesan cheese, 2 tablespoons fresh chopped parsley, 0.5 teaspoon salt, and 0.25 teaspoon black pepper; toss until the cheese melts and noodles are well coated.
Taste and adjust seasoning if needed.
Serve immediately while warm and glossy.
