How to make roasted garlic mashed potatoes
Follow this step by step photo tutorial, then scroll down to the recipe card for the full ingredients list and method.
Preheat the oven to 350 F (175 C). Rub the oil onto the whole, unpeeled heads of garlic, then wrap them in foil and place on a baking tray. Bake for 1 hour.
Meanwhile, cook the potatoes in a pan of boiling water until soft, then drain, cool slightly and chop.
When the garlic has cooled enough to handle, cut in half, then squeeze the roasted garlic cloves into a small pot. Add the butter and heat until melted.
Remove from the heat and allow the butter to infuse with the garlic for at least 5 minutes. If you have time, leave it longer for a more intense garlic flavor.
Mash the cooked potatoes with the melted garlic butter (including the cooked cloves, or you can strain them out), milk and sour cream and season with a little salt and pepper.
Tips
Garlic can be roasted in the oven up to 2 days ahead of time. Just wrap and store in the fridge until ready to infuse the butter.
If you don’t want chunks of garlic, then remove them from the garlic butter before mashing. Strain them out with a mesh strainer or use a slotted spoon.
You can make the garlic butter ahead of time and leave it to infuse longer for a more intense flavor.
Make it lighter with skimmed (1%) milk and low fat sour cream for a lower fat option.

My kids don’t like the chunks of garlic, so we love my recipe with infused garlic butter. You can strain out the garlic and still get lots of great flavor. That’s what makes these the BEST!

To Make It Vegan: To make this recipe vegan, use a vegan butter substitute and non-dairy milk like soy. You can use unsweetened almond or coconut yogurt in place of the sour cream but it may change the flavor slightly so add slowly and test as you go. Often you can find vegan dairy free sour cream at the grocery store.

FAQs
What are the benefits of eating roasted garlic? Roasted garlic is nutritionally beneficial in many ways. It’s been shown to reduce cholesterol, blood pressure and contains vital nutrients and minerals.
Can you freeze roasted garlic? You can freeze your roasted garlic mashed potato when it is cooled and mashed. Just add the mash to an ice cube tray and remove once it’s frozen. Then add the frozen cubes to a freezer-safe bag.
Should you bake or boil potatoes for mashed potatoes? Either option will work, however, baking or roasting them will result in a drier potato which may need additional liquid to mash properly.
How do I keep my mashed potatoes from becoming gluey? Be sure to mash your potatoes, and don’t blend them or whiz them up in a food processor. This is to keep the starches from developing and taking on a gummy texture. Try not to over-work your mashed potatoes. Also, choosing a variety of potato that works well for mashing is best. Try Russett, Maris Piper or King Edward for light and fluffy mash, or Yukon gold for slightly denser mash.
