Place the peeled garlic cloves in an oven-safe container and pour in enough extra virgin olive oil to fully submerge the cloves. If using a small container, be sure to fill only 3/4 of the way to prevent the oil from boiling over.
Layer the thyme and rosemary stems, then season with a generous pinch of salt.
Bake for 30-40 minutes, preferably with a lid, until the cloves are light golden brown and fragrant. Remove from the oven and let it sit for 5-10 minutes before using.
Garlic and Herb Mashed Potatoes
Peel and cut the potatoes into large, equal-sized pieces, about 1 inch thick. Cook the potatoes in a pot of salted boiling water until they are fork-tender, which should take about 15-20 minutes depending on their size. Remove from the heat and drain.
Add 3/4 of the garlic (without the oil) to a bowl or stand mixer. Using a fork, crush the garlic to create a paste.
Add the drained hot potatoes to the bowl. Add in the butter, half-and-half, and chopped herbs. Generously sprinkle with salt, then mash using your preferred method—whether a masher, hand mixer, or stand mixer. For extra flavor, add 1-2 tablespoons of the confit olive oil.
Serve with a drizzle of the confit oil and additional garlic cloves on top.
