Start by gathering everything needed for the sauce. Having all your ingredients measured out will streamline the process and help you feel like a culinary superstar. Lay out your butter, cream cheese, garlic powder, milk, Grated Parmesan cheese, black pepper, Italian seasoning, and nutmeg.

In a medium nonstick saucepan, melt the butter over medium heat. Make sure not to let it brown; we're looking for soft, melting goodness rather than crispy bits. You want that butter to be as silky as possible to serve as the base for your sauce.

Once the butter is melted, add the softened cream cheese and the garlic powder to the saucepan. Use a whisk to stir them together. You’re looking for a smooth consistency—this might take a little bit of elbow grease, but keep whisking! You want all the lumps of cream cheese gone and a lovely buttery mixture.

Now it’s time to add the milk. Pour it in slowly, whisking constantly to avoid lumps. Start by adding just a bit of milk, getting that base nice and smooth before gradually introducing the rest. The goal here is a silky sauce that’s coming together nicely.

Once your mixture is smooth, add the grated Parmesan cheese, black pepper, and any optional seasonings you wish to include. Continue to whisk until the cheese is fully melted and the sauce is creamy. This should take around 4-5 minutes. Taste before removing from heat; adjust seasonings to your preference.

Remove the sauce from the heat when it has reached your desired thickness. Remember, the sauce will thicken as it cools, so if it seems a little too thick, you can always whisk in a splash more milk until you get the consistency you love.

Your alfredo sauce is now ready! Toss it with freshly cooked pasta of your choice, and serve immediately. The sauce coats the noodles beautifully, becoming one with each bite. Trust me, everyone will be coming back for seconds!
