Cook pasta while making alfredo sauce.

Melt butter on medium heat in a large saucepan. Add salt, pepper, and flour. whisk until smooth.

Slowly pour in milk and whisk until combined.

Add 1/2 cup Parmesan cheese.(I like to use 3/4 because I love the Parmesan flavor) Whisk until cheese melts into mixture and becomes smooth. Add Italian herb blend. Whisk.

Taste with a spoon and adjust cheese and seasoning if necessary. Continue whisking until sauce thickens to desired consistency. Sauce will also thicken as it cools.

If you're sauce thickens to much you can always add more milk or pasta water to thin it out. Enjoy!
