Step 1

Boil a large pot of water over high heat.

Step 2

While waiting for the water to bowl, peel the garlic and gather all other ingredients.

Step 3

When the water is boiling, salt the water and add the pasta. Cook according to manufacturers instructions.

Step 4

Heat a large skillet over low heat. As it is heating up, add in 3 tablespoons of butter, then grate the garlic on the butter as it is melting. As soon as you’ve grated the garlic, turn the heat up to medium high heat, and stir for 1 minute until the butter is melted and the garlic is fragrant.

Step 5

Pour in the heavy cream and milk, stir and cook for 1 minute. Add in the pesto, stir to combine. Turn heat back to low, then add in the parmesan cheese. Stir until it is melted.

Step 6

Grab the cooked pasta with tongs out of the boiling water and add it directly to the sauce. Toss to combine. Add pasta water if the sauce needs to be thinned out. Serve immediately.
