Step 2: Build the Garlic Butter Base - Set a
large skillet or Dutch oven over medium heat and melt the butter. Add the minced garlic and stir for about 30 seconds, just until it smells fragrant. Keep an eye on it because garlic can go from golden to bitter quickly. Sprinkle in the flour and whisk constantly for one full minute. This brief cooking time gets rid of the raw flour taste and creates the thickening base that will help the sauce wrap around the pasta instead of sliding to the bottom of the bowl.
