Ingredients

1 bulb Garlic
½ stick unsalted butter (¼ cup)
1 tablespoon all-purpose flour
2 cups Half and Half
½ cup Parmesan cheese freshly grated
salt and pepper to taste
1 tablespoon chopped fresh parsley optional

Instructions

ROAST: Preheat the oven to 425°F. Cut the top ¼th off the bulb of garlic, exposing the cloves. Make a foil pouch and cover bulb in olive oil and sprinkle with salt. Seal packet and roast for 45-75 minutes until cloves are golden brown and softened. Allow roasted garlic to cool enough to handle, then squeeze out the roasted cloves. A glove is handy for this as the roasted garlic cloves will be sticky. Mash up the cloves and set aside.
SAUCE: Heat a skillet over medium heat. Melt butter in the skillet, then slowly whisk in the flour. Stir out all the lumps and cook for about 2 minutes. Slowly whisk in the half and half and stir out all the lumps. Add in mashed garlic, reduce heat to low and simmer for about 10 minutes, stirring occasionally. Once sauce has reached desired consistency, remove from heat and stir in parmesan cheese. Season with salt and freshly ground black pepper to taste.
SERVE: Boil pasta according to package directions. Make sure to heavily salt the pasta water. Reserve about ½ cup of pasta water. Drain pasta and mix into sauce with a splash of pasta water. Use more pasta water if needed to loosen up the sauce.

Notes

Serve with chicken or shrimp.

Troubleshooting:

Sauce is too thick - If your sauce comes out too thick, you can add a little more half and half or milk to loosen it up. You can also do this by adding pasta water.
Sauce is too thin - If your pasta sauce is too thin, simmer on low while stirring until it reduces to your desired consistency.

Store leftovers in an airtight container in the refrigerator for 3 days.

Store pasta separate from the sauce.

It is not recommended to freeze Alfredo sauce since it is mostly dairy.

Reheat leftover sauce in a skillet slowly over low heat to prevent the sauce from breaking.
