What is garlic confit?
Garlic confit is just garlic cooked slowly in oil until itโs soft and sweet. The strong flavor turns mellow and rich, perfect for mashed potatoes.
Mix it in, and the garlic melts right into the potatoes. Itโs not too strong, just super tasty and comforting. Check out more confit recipes: Duck Confit and Potato Confit.
You can use the roasted garlic for more than just mashed potatoes. Try spreading it on toasted bread for quick crostini. You can also mix it into dips, spreads, soups, or stews. Stir it into risotto, add it to grilled meats, or mix it with mayo.
Recipe ingredients
Starchy potatoes are often called floury potatoes or mealy potatoes. Common varieties of floury or starchy potatoes include Russet, Yukon Gold, Idaho, King Edward, Maris Piper, and Kennebec. Check out the Rosemary Garlic Mashed Potatoes and the Truffle Mashed Potatoes, too.
Garlic confit: You will need whole bulbs of fresh garlic.
Parmesan: I always recommend using freshly grated cheese from a wedge; it tastes and melts better.

How to make mashed potatoes with roasted garlic and Parmesan?
Step #1: Place the cloves in a small ovenproof dish and add olive oil. You want them to be nicely coated.
Step #2: Roast the garlic until it becomes very soft (to be able to mash it with a fork).
Be careful of the smallest cloves if you're using a whole bulb. They roast faster and can get too dark, so it's best to leave them out.
Step #3: Cook for 15-20 minutes or until tender. Drain well.
Step #4: Mash with the potato ricer or a regular potato masher.
Make the potato mash
Combine the potatoes with the heated milk, garlic, butter, grated Parmesan, and seasoning. Be generous with the salt, but adjust the quantity as required; you will need less salt if using salted butter for the mashed potatoes.

Good to know!
Starting with cold water helps the potatoes cook evenly. It keeps the outside from getting too soft before the inside is ready, so the texture stays just right, not mushy.
Use a potato masher or a ricer for a smooth mash. Avoid over-mashing to prevent a gluey texture.
Storage
Leftovers can be refrigerated for 3-4 days. Reheat gently on the stove or in the microwave. Add a splash of milk and stir before reheating.

Notes
- Vegan or dairy-free alternative: Use vegan/dairy-free options like almond milk and vegan butter or margarine.
- Use room-temperature butter and warm milk when mashing for better absorption and creaminess. Starting with cold water when cooking potatoes ensures even cooking and prevents the outer layers from overcooking before the insides are done.
- Mashing: Use a potato masher or a ricer for a smooth mash. Avoid over-mashing to prevent a gluey texture.
