Step 1

First, add the buttermilk, bouillon powder, cornstarch, and black pepper to a sauce pan. Use a whisk to whisk the powdered ingredients into the buttermilk.

Step 2

Turn on the heat to medium-high. Whisking frequently, bring the mixture to a boil.

Step 3

Once boiling, reduce heat to medium and continue to whisk often until the sauce is as thick as you would like it. (Anywhere from 2-6 minutes after the mixture comes to a boil.)

Step 4

Taste and add salt if needed.

Step 5

Keep the sauce simmering as you prepare the pasta. Drain the pasta well, plate, and ladle on the sauce. Top with parmesan and torn basil leaves. Enjoy!
