Alfredo Sauce

We did a massive Costco shopping trip yesterday and I was coerced into buying one of their amazing, ready to bake meals.  Tonight when I put it in the oven, I realized I had time on my hands!  My husband was home and playing with the toddler and our infant was asleep in the swing.  I decided to make something quick and freeze it for the future.  I had all of the ingredients for Alfredo Sauce, which I've always been afraid to make (it sounds like so much work!) so I went for it.  I found the key to making this successfully is patience!  It's cooked at a low heat so it takes awhile, but from the little taste I did, it's worth it! 
I found the recipe at Once a Month Mom, my current bible on how to make-ahead meals!  I did double the recipe.  It calls for 4 oz of cream cheese which is half of a brick.  I didn't know what I'd do with the other half so I just doubled the recipe.  The single recipe makes 1 bag, enough for 4 servings (or 1 pound of pasta).

Alfredo Sauce
3 Tbsp butter
2 Tbsp flour
2 cups milk (I used whole)
4 oz cream cheese
1/4 cup parmesan cheese (I used shredded, and a tad more than it calls for)
1 tsp garlic powder
1/2 tsp salt
1/2 tsp pepper

Melt butter in a saucepan on medium low heat.  Once melted, whisk in flour.  Gradually add milk, whisking as you go.  The original recipe didn't tell you when to add the salt, pepper and garlic powder, so I did it at this point and it worked well.  Once all the milk is added and it's hot (but not boiling!), add the cream cheese.  Whisk to combine. (This took awhile!).  Heat the sauce back up and add parmesan cheese.  Simmer until melted and mix well. 

I wanted to freeze it, so this is what I did:
Cooled the sauce in a container on the counter.  Our freezer is relatively full so I opted to pour the sauce into a 1 quart freezer bag.  Label and lay flat in your freezer so it freezes that way and takes up less room.  To serve, just thaw and reheat!
