These olive oil mashed potatoes, from that doyenne of everything Italian Lidia Bastianich, swaps in olive oil for the traditional butter and the result is an indulgent, smooth, dairy-free mash. You might just never go back to old-school spuds.
Who doesn’t like mashed potatoes? Of course we love them, but everyone wants to be careful about adding too much butter. So try making them the way my nonna used to make them in Italy—with olive oil, or with garlic and olive oil. They’re healthier, and still a favorite at our table.–Lidia Matticchio Bastianich
Why Our Testers Loved This
Our testers can’t say enough good things about these easy, 4-ingredient mashed potatoes. They’re calling them light, delicate, and luscious. Alexander C describes them as “some of the best mashed potatoes” he’s ever tried.
Notes on Ingredients
- Potatoes–Yukon Gold or russet potatoes are best here. Avoid red or other waxy varieties as they don’t mash well.
- Olive oil–Depending on your personal preference, you may need a little more or less than the 1/4 called for here. Choose an olive oil that is light in flavor so that the grassy flavor of the oil doesn’t overwhelm the potatoes.
How to Make This Recipe
- Cook the potatoes. Cover the potatoes with cold salted water and bring to a boil. Cook until tender, then drain.
- Mash the potatoes. Use a food mill, ricer, or handheld masher to mash the potatoes, then stir in the olive oil and season with salt and pepper.
Why are potatoes cooked with their skins on?
Cooking the potatoes with their skins on prevents the spuds from becoming waterlogged and gummy. It’s also a great time-saver as the skins of the cooked potatoes should just slip right off.
Can I add garlic?
Definitely. To make garlic olive oil mashed potatoes pour the olive oil in a large skillet, add 3 whole peeled garlic cloves, and heat over medium-low heat until the garlic is softened and toasty at the edges. Gently stir the garlic cloves into the mashed potatoes along with the olive oil, warning guests as to the presence of whole cloves of garlic.
How do olive oil mashed potatoes differ from traditional creamy mashed potatoes?
Mashed potatoes are usually made with plenty of cream and butter, making them heavy and rich. Using olive oil results in lighter, fluffier mashed potatoes. Using olive oil also makes them suitable for dairy-free and vegan diets.
What should I serve with these potatoes?
Mashed potatoes are welcome alongside any type of roasted meat, but we especially love them at Thanksgiving dinner.
If you’re trying to keep your meal dairy-free, serve these potatoes with simple roast turkey, bread stuffing with bacon and apples, green beans with bacon and shallots, and basic pan gravy.
If you’re keeping your meal vegan, try some of these vegan Thanksgiving recipes.
- For even easier peeling, score your potato skins with an ‘x’ before boiling.
- Be sure to choose a good quality light olive oil so that the flavor doesn’t overpower the mashed potatoes.
- Mashed potatoes with olive oil can be stored in a sealed container in the fridge for up to 4 days. Reheat in a saucepan over medium-low heat, stirring frequently.

Recipe Testers’ Reviews
Perfect, light, and delicate mashed potatoes. Such a nice change from the heavy cream and butter version. I couldn’t imagine olive oil in place of butter and my family was hesitant to try them, but it was a hit with everyone!

One word that sums up this recipe: luscious. Leave it to master Italian chef Lidia Bastianich to share what comes out to be some of the best mashed potatoes I’ve ever tried. Seriously, I don’t just say that.
The recipe comes together simply and is very easy to double or triple, depending on how many people you’re serving. I used 2 standard Idaho potatoes, which boiled for around the 30-minute mark. Peeling was a snap but I’d recommend scoring the potato skin with an “x” on each tip before boiling for even easier removal.
I’m thinking that this recipe might even replace my famous twice-cooked mashed potatoes for Thanksgiving. Yes, these are that good.
