This recipe is very easy and fairly low fat, compared with regular Alfredo Sauce.
2 TBS butter
3-6 cloves garlic, minced
4 oz cream cheese, softened
1 cup milk
3 oz Parmesan cheese, grated (about 1 cup)
1/2 tsp black pepper
1/2 tsp salt, or more to taste, if needed
In medium skillet, melt butter over medium heat. Add garlic and cook for about 2 minutes, stirring constantly. Add cream cheese and stir with whisk until smooth. Add milk gradually, whisking with each addition. Stir in Parmesan cheese, pepper, and salt. Cook for 2-3 minutes for a thicker sauce or remove right after cheese is melted for a thinner sauce. Serve immediately over hot, cooked noodles.
