Set up: Place a fine mesh-sieve over a bowl. Line a large plate with a paper towel and set aside.
Prep the garlic: Break 1 head garlic into individual cloves, and peel each clove. Trim off the root end of each clove, and thinly slice into 1/16-inch (or thinner) slices using a sharp knife or a mandolin.
Microwave: Place the garlic in a medium bowl with ⅔ cup neutral oil (or more if needed to fully submerge the cloves). Microwave in 1-minute increments, stirring in between, until the garlic is just beginning to take on color.Then, microwave in 15-second bursts, stirring as needed, until the garlic is evenly golden brown.Note: The garlic will continue to take on color even after removing it from the microwave, so make sure to take it out just before it's perfectly golden brown.
Strain: Immediately pour the mixture through the sieve to separate the garlic and oil. Transfer the garlic chips to the paper towel-lined plate to cool and crisp.
Storage: Once fully dry, use immediately or store garlic chips in an airtight container at room temperature for up to 2 weeks. For longer storage, add a food-safe silica gel packet to the container, and store for 3 - 4 weeks. Transfer garlic oil to a clean, airtight container or jar and store in the fridge for 3 - 5 days.
