My Passion for Potatoes: A Culinary Journey

My love affair with potatoes runs deep. They are one of those ingredients that I genuinely never tire of cooking or eating. I’ve explored countless preparations, always marveling at their ability to transform. I’ve enjoyed them roasted in duck fat until they achieve that irresistible crisp, smashed and infused with fragrant garlic confit butter, layered into a decadent creamy and cheesy gratin, or even stuffed to perfection with cream cheese. And, of course, there’s the beloved classic potato mash.

However, as much as I appreciate traditional methods, I recognized a need for a more inclusive approach. Most mashed potato recipes, while delicious, simply don’t cater to our vegan or dairy-free friends. This gap inspired the creation of this very special recipe. It’s entirely plant-based, yet its richness, fluffiness, and robust flavor genuinely mask its dairy-free nature. You honestly wouldn’t know the difference!

Beyond being plant-based, what truly elevates this dish is its incredible depth of flavor. The potatoes aren’t just boiled in water; they’re cooked in a savory vegetable or chicken broth. But the real game-changer is the olive oil itself – generously infused with aromatic garlic. This simple yet powerful technique transforms a humble side dish into something truly extraordinary, making these olive oil mashed potatoes a staple for any occasion.

Essential Ingredients for Our Olive Oil Mashed Potatoes

Crafting these silky, flavorful, and entirely dairy-free mashed potatoes requires only a few carefully selected ingredients. Each component plays a crucial role in achieving the perfect balance of taste and texture.

Potatoes: The foundation of any great mash. For a light and exceptionally fluffy result, opt for starchy varieties like Sebago or Russet potatoes. If you prefer a slightly creamier, denser mash, Yukon Gold potatoes are an excellent choice. Ensure they are peeled and quartered for even cooking.
Chicken or Vegetable Broth: This is a secret weapon for boosting flavor. Cooking your potatoes in broth instead of plain water imparts a savory depth that is unmatched. For a truly vegan dish, stick with high-quality vegetable broth. The starchy cooking liquid also becomes a vital binder for loosening and enriching the mash without dairy.
Extra Virgin Olive Oil: The undisputed star of this recipe! A good quality extra virgin olive oil is paramount. It provides the luscious richness and body that butter or cream typically would, along with its own distinct fruity and peppery notes. It’s not just a substitute; it’s an enhancement.
Garlic: Fresh garlic bulbs are essential for infusing the olive oil. The slow infusion process mellows the garlic’s pungency and imbues the oil with its sweet, aromatic essence.
Fresh Rosemary: A sprig of fresh rosemary adds an earthy, piney aroma that complements the garlic beautifully during the oil infusion, adding another layer of sophisticated flavor.
Salt and Pepper: Crucial for seasoning. Potatoes are notorious for absorbing salt, so generous seasoning throughout the process is key to a flavorful finished product.

Chef’s Secrets for Irresistible Olive Oil Mashed Potatoes

Achieving perfectly creamy and flavorful dairy-free mashed potatoes is an art, and these expert tips will guide you to culinary success:

Always Cook in Broth, Not Just Water: This is a game-changer! Boiling your potatoes in vegetable or chicken broth imbues them with incredible savory flavor from the start. More importantly, it creates a starchy, flavor-packed liquid that is essential for bringing the mash together to a creamy consistency without the need for cream or milk.
Don’t Discard That Cooking Water: After draining your cooked potatoes, make sure to reserve at least one cup of the starchy broth. This liquid is gold! Slowly add it back into the potatoes as you mash. It helps to loosen them, ensuring they are extra fluffy and never gluey, and further enhances the flavor.
Gently Warm Your Olive Oil: Before incorporating the garlic and rosemary-infused olive oil, ensure it’s slightly warm. This subtle warmth helps the oil more effectively coat every single potato particle, distributing its rich flavor and luxurious texture evenly throughout the mash.
Resist the Urge to Over-Mash: While we aim for creamy, over-mashing can lead to a sticky, gluey, and undesirable texture. Embrace a slightly rustic texture. A good old-fashioned potato masher or even a sturdy wooden spoon is often better than an electric mixer for these potatoes, as it prevents overworking the starch.
Season Generously and Taste as You Go: Potatoes are like sponges for salt. Add salt during the cooking process and be sure to taste and adjust seasoning throughout the mashing. Don’t be shy – proper seasoning truly makes the flavors sing. Freshly ground black pepper is also essential.
Serve Immediately for Best Results: Mashed potatoes are at their absolute peak when hot, fresh, and fluffy. While they can be reheated, they are undeniably best enjoyed straight from the pot. Plan your meal so the mash is the last component finished.
Choose Your Mashing Tool Wisely: While potato ricers or food mills can produce incredibly smooth results, for these olive oil mashed potatoes, a simple potato masher is often ideal. Its slightly less aggressive action helps prevent over-mashing and preserves that lovely rustic texture. The key is to boil the potatoes until they are extremely tender, almost falling apart, making mashing effortless.
Steam Dry After Draining: After draining the potatoes, return them to the empty hot pot and cover with a clean tea towel for 5-10 minutes. This allows any residual moisture to steam off, resulting in a drier, fluffier potato ready to absorb the flavorful olive oil without becoming watery.

By: Daen Lia

Prep Time: 10 mins

Cook Time: 30 mins

Servings: 4

Ingredients

2 lbs potatoes, peeled and quartered (starchy varieties like Russet or Sebago recommended)
3/4 cup extra virgin olive oil
2 garlic bulbs, tops cut off to expose cloves
1 sprig fresh rosemary
2 L vegetable or chicken broth
Salt, to taste
Freshly ground black pepper, to taste

Instructions

Prep Garlic: Cut the top off the garlic bulbs roughly 2cm down from the top so the cloves are exposed. This allows for maximum flavor infusion.
Infuse Olive Oil: In a small pot, combine the olive oil, the prepared garlic bulbs, and the fresh rosemary sprig. Cook over very low heat for 30 minutes, or until the olive oil is thoroughly infused with garlic and rosemary flavor. Carefully strain the oil through a fine mesh strainer into a glass jar, setting the softened garlic cloves aside for later optional use.
Prepare Potatoes: While the olive oil infuses, prepare the potatoes. Place the peeled and quartered potatoes in a large pot. Cover them with vegetable or chicken broth, adding a pinch of salt. Bring the pot to a boil over high heat, then reduce the heat to a simmer and cook the potatoes for 20 – 25 minutes. They should be very soft, allowing a skewer or knife to pass through them with no resistance.
Drain & Steam Potatoes: Reserve up to 1 cup of the flavorful cooking water. Drain the potatoes thoroughly in a colander. Immediately return the drained potatoes to the empty hot pot and cover with a clean tea towel. Let them sit for about 10 minutes; this allows any excess moisture to steam off, ensuring fluffier mashed potatoes that can better absorb the oil.
Mash to Perfection: Place the steamed potatoes back into the pot. Using a sturdy potato masher, begin mashing. Gradually incorporate up to 1 cup of the reserved cooking water and up to 1/2 – 3/4 cup of the infused olive oil, mashing until the potatoes reach your desired creamy and fluffy consistency. Add more liquid or oil a tablespoon at a time if needed.
Season & Serve: Season generously with salt and freshly ground black pepper to taste. Sprinkle over some fresh rosemary for garnish. If desired, gently squeeze the softened, cooked garlic cloves over the top of the mash for an extra layer of savory goodness. Serve immediately while hot and fluffy.

Notes

Potato Variety: For the best results, use starchy potatoes like Sebago or Russet for a light and fluffy mash. If you prefer a slightly denser, creamier texture, Yukon Gold potatoes work wonderfully.
Broth is Key: Cooking potatoes in broth instead of plain water significantly enhances their flavor, which is crucial for dairy-free mash.
Save the Starchy Water: This reserved cooking liquid helps achieve creaminess and lightens the mash without adding dairy.
Warm Olive Oil: Slightly warming the infused olive oil ensures it blends seamlessly and coats the potatoes thoroughly, distributing flavor and richness evenly.
Avoid Over-Mashing: Mashing too vigorously or for too long can break down potato starches, leading to a gluey texture. Aim for a rustic mash with a potato masher for best results.
Proper Seasoning: Potatoes require a good amount of seasoning. Taste and adjust salt and pepper throughout the process.
Serve Fresh: Mashed potatoes are always best served hot and fresh.

Frequently Asked Questions About Olive Oil Mashed Potatoes

Are olive oil mashed potatoes vegan?

Absolutely! This recipe for mashed potatoes is entirely vegan and dairy-free. Extra virgin olive oil replaces traditional butter and cream, providing all the richness and luscious flavor without any animal products. It’s a perfect plant-based alternative.

Can I use water instead of broth for mashed potatoes?

While you certainly can use water, we highly recommend cooking the potatoes in vegetable or chicken broth. The broth infuses the potatoes with a much deeper, more complex flavor, which is key to creating truly delicious and creamy dairy-free mashed potatoes. Using water will result in a less flavorful mash, requiring more seasoning later.

What kind of potatoes are best for mashed potatoes?

For the fluffiest and lightest mashed potatoes, starchy varieties like Russet (Idaho) or Sebago are ideal. Their high starch content breaks down easily, yielding a wonderfully airy texture. If you prefer a slightly creamier and more buttery texture, Yukon Gold potatoes are an excellent choice as they have a medium starch content.

How do I make mashed potatoes creamy without milk or butter?

The secret lies in two crucial elements: high-quality extra virgin olive oil and the starchy cooking water from the boiled potatoes. The olive oil provides richness and a smooth mouthfeel, while the reserved starchy broth helps to emulsify the mixture and create that desired silky, creamy consistency without any dairy products.

Can I add other flavors to olive oil mashed potatoes?

Absolutely! This recipe is a fantastic base for customization. Fresh herbs like thyme, chives, or sage would work beautifully alongside or in place of rosemary. You can also experiment with different infused oils – chili-infused olive oil for a spicy kick, or even lemon-infused olive oil for a brighter, fresher profile. Roasted garlic cloves (instead of infused) can also be mashed in for an intense garlic flavor.

Why did my mashed potatoes turn out gluey?

Mashed potatoes can become gluey if they are over-mashed, especially when using an electric mixer or food processor. Over-mashing causes the potato starches to break down excessively, releasing too much starch and resulting in a sticky, pasty texture. For best results, use a potato masher or ricer, and stop mashing as soon as the desired consistency is reached.

Creative Ways to Serve Your Olive Oil Mashed Potatoes

These luxurious Olive Oil Mashed Potatoes are more than just a side; they are a versatile accompaniment that elevates almost any meal. Their creamy texture and savory garlic notes make them particularly perfect for soaking up delicious sauces and gravies. Here are some fantastic pairing ideas:

With Roast Chicken: Serve alongside a succulent roast chicken with a vibrant salsa verde for a truly comforting and flavorful meal. The mash is perfect for balancing the rich chicken and bright sauce.
Alongside Creamy Mushroom Chicken: Pair with chicken breast in a rich creamy mushroom sauce. The olive oil mash will soak up every drop of that irresistible sauce.
With Honey Garlic Lamb: Complement tender honey garlic butter lamb cutlets for a hearty and flavorful dinner. The garlic in the mash will echo the flavors in the lamb beautifully.
Alongside Garlic Butter Shrimp: Enjoy with juicy garlic butter shrimp (prawns). The mild, yet flavorful mash provides a wonderful counterpoint to the seafood.
As a Base for Vegan Gravy: A classic pairing! A rich mushroom or vegetable gravy poured over a mound of these creamy potatoes is pure vegan comfort food heaven.
With Roasted Vegetables: For a simple, healthy, and satisfying vegan meal, serve a generous portion of the mash with a medley of your favorite roasted seasonal vegetables.

Storing and Reheating Your Olive Oil Mashed Potatoes

One of the great things about these dairy-free mashed potatoes is how well they store, making them perfect for meal prep or enjoying leftovers!

Fridge: Store any leftover olive oil mashed potatoes in an airtight container in the refrigerator for up to 3 days. When ready to enjoy again, reheat gently on the stovetop over low heat, or in the microwave. To help them regain their creamy texture, add a splash of extra vegetable broth or a drizzle of fresh olive oil while reheating, stirring until smooth and warmed through.

Freezer: These mashed potatoes are surprisingly freezer-friendly! To freeze, allow them to cool completely, then transfer them to a freezer-safe, airtight container or heavy-duty freezer bags. They can be stored for up to 1 month. When you’re ready to eat, thaw them overnight in the refrigerator. Reheat on the stovetop or in the microwave, adding a drizzle of olive oil or broth and stirring frequently until they are hot and creamy once more.
