I use this alfredo sauce alone or in baked ziti.
½ cup Butter
2-4 oz. Cream Cheese (depending how much of a cream cheese taste you want)
1 pint Heavy Whipping Cream
¾ tsp. Garlic Powder
1 cup Parmesan Cheese
In saucepan, melt butter. Add cream cheese, heavy whipping cream, garlic powder, salt, and pepper. Whisk constantly until it boils. Bring to a boil. Stir every few minutes. Simmer for 20 minutes. Take from heat and stir in cheese. Cover and let sit for 5 minutes.
Boil the ziti according to directions. Drain. Put the pasta in a 9x13 pan. Pour the alfredo sauce above over the ziti. Cook the meat of your choice (Hamburger, Sausage, etc...). Mix it with jarred or homemade spaghetti sauce (We prefer Tomato and Basil Classico). Pour the meat sauce over the alfredo sauce. Top with the mozzarella cheese and bake at 350 for 30 minutes.
