12 or 16ounce boxpasta of choice (I used about 16 ounces of macaroni noodles here)
Instructions
Boil/cook noodles according to instructions on package, and drain.
On a separate burner, melt butter in a medium saucepan over medium heat.
Whisk together cold milk, cornstarch, salt, garlic powder, onion powder, paprika, and white pepper in a small bowl or measuring cup. Add this mix to the butter in the sauce pan.
Cook over medium heat, whisking frequently to prevent clumping. After several minutes, or once thickened, remove pan from heat.
Immediately add cheddar, mozzarella, and parmesan to hot saucepan and stir briefly until cheese is melted.
Pour sauce over prepared noodles, and stir to combine. Serve hot.
