In a large skillet, melt the butter over medium heat.

Add the minced garlic to the melted butter and sauté for about 1 minute until fragrant.

Slowly pour in the half and half, stirring constantly to combine.

Gradually whisk in the grated Parmesan cheese until fully melted and smooth.

Sprinkle in salt, pepper, and Italian seasoning if using.

Let the sauce simmer for 2-3 minutes, stirring occasionally.

If the sauce is too thick, add a splash of pasta water or more half and half.

Remove from heat and serve over your favorite pasta.
