Equipment

Pot
Saucepan
Cheese Grater

Ingredients

8 tbsp butter 1 stick
3 tbsp flour
2 tbsp minced garlic
2 cups heavy cream
1 cup milk
1 1/2 cups Parmesan cheese freshly grated
1/2 cup Romano cheese freshly grated
1 box fettucine
salt to taste
pepper to taste
parsley freshly chopped

Instructions

Begin by boiling a pot of water and cooking the fettuccine al-dente based on the package instructions. As the noodles cook, begin making the sauce.
In a large saucepan on the stovetop, melt butter over medium heat. Once melted, add minced garlic and cook for about one minute or until the garlic begins to sizzle and turns light golden brown.
Next, make a roux by sprinkling flour into the pan and whisking it together with the butter and garlic.
Once the roux is formed, slowly add the heavy cream and milk, continuously whisking as you pour.
Bring the Alfredo sauce to a lower simmer and allow it to thicken, then add the cheese ½ a cup at a time, slowly whisking and melting it down until it’s incorporated.
Salt and pepper the sauce to your taste, then add the drained fettuccine noodles to the Alfredo. Toss together to coat.
Top with freshly grated Parmesan and parsley, then serve warm.

Notes

I prefer using whole milk in this recipe to make it extra creamy.
If you want to add some vegetables to this recipe, add spinach to the sauce when you add the fettuccine. The heat will wilt the spinach.
I recommend using freshly ground pepper in this recipe for extra flavor.
