Begin by bringing a large pot of salted water to a rolling boil. Add the spaghetti and cook according to package instructions, usually around 8-10 minutes, until al dente. Stir occasionally to prevent sticking.
While the pasta is cooking, heat a skillet over medium heat. Add the extra virgin olive oil and melted butter. Once hot, add the minced garlic and sauté for 1-2 minutes until fragrant, being careful not to burn it.
Once the spaghetti is cooked, reserve about 1 cup of the pasta water, then drain the rest using a colander. Add the drained spaghetti directly to the skillet with the garlic oil. Toss to combine, adding reserved pasta water as needed to create a silky sauce.
Sprinkle in salt, ground black pepper, and red chili flakes. Toss everything together until well combined. Adjust seasoning according to your taste preferences.
Remove from heat and transfer the Easy Spaghetti to serving plates. Garnish with finely chopped parsley leaves for a fresh finish. Enjoy your meal hot!
