Step 1

Bring a large pot of generously salted water to a boil and cook the pasta according to the package directions to al dente, about 12-14 minutes.

Step 2

Reserve 1 cup pasta water then drain the pasta. Set aside.

Step 3

Place the now empty pot on the stove. Add the butter and melt over medium heat.

Step 4

Whisk in the garlic and cook for 1 minute or until translucent. Lower the heat, if needed, to avoid browning.

Step 5

While still on low heat, add in the Greek yogurt and parmesan cheese. Cook, stirring constantly, for a minute or two just until the yogurt is warmed through and the cheese is melted. Add the reserved pasta water as needed, 1 tablespoon at a time, to thin and smooth out the sauce.

Step 6

Season the sauce with salt and pepper. Taste and adjust seasoning.

Step 7

Add the drained pasta to the pot and gently toss to ensure all the pasta is coated with the sauce.

Step 8

Transfer to a serving bowl and top with parsley, parmesan cheese and red pepper flakes, if preferred. Serve!
