Mashed Potatoes Recipe Without Butter: Silky Smooth With Olive Oil

Creamy mashed potatoes without butter are not only possible but can be even more flavorful with the right approach. This recipe uses olive oil as a rich, heart-healthy alternative that delivers a velvety texture.

The key is using starchy potatoes and warming the olive oil before mixing it in. This ensures the oil incorporates smoothly, creating that signature silky consistency you expect from classic mashed potatoes.

You’ll end up with a dish that’s every bit as satisfying as traditional versions, but lighter and dairy-free. The olive oil adds a subtle fruitiness that complements the natural sweetness of the potatoes.

Perfect for weeknight dinners or holiday tables, this method proves you don’t need butter for restaurant-quality results.

Ingredients for Mashed Potatoes Recipe Without Butter

Simple, flavorful ingredients for silky dairy-free mashed potatoes everyone will love.

The potatoes are everything here. Yukon Golds have the perfect starchy-sweet balance for that velvety texture. I grab mine from Whole Foods or the local farmers market—look for firm, unblemished spuds. Extra-virgin olive oil is non-negotiable; the good stuff (like California Olive Ranch) adds that fruity depth. Warm it gently before mixing—cold oil won’t emulsify right.

No Yukon Golds? Russets work too (just add a splash more almond milk). Out of fresh rosemary? Dried at one-third the amount or swap in thyme. Almond milk can be any unsweetened plant milk—oat milk adds extra creaminess. Skip the nutritional yeast if you’re not into that cheesy vibe (but I always keep Bragg’s on hand for this).

Mashed potatoes reheat like a dream. Store in an airtight container for up to 5 days in the fridge, or freeze for 3 months. To revive, warm on the stove with a splash of milk (don’t microwave—they’ll turn gluey).

Step-by-Step Instructions for Mashed Potatoes Without Butter

Here’s my method for achieving that perfect creamy texture using a simple olive oil trick.

Step 1: Boil Yukon Gold Potatoes Until Fork-Tender

Place the 2 lb Yukon Gold Potatoes in a large pot and cover with cold water by about 1 inch. Add 1 tsp Sea Salt to the water—this seasons the potatoes from within as they cook.

Bring to a boil over high heat, then reduce to medium and cook for 15-20 minutes until the potatoes are fork-tender. You’ll know they’re ready when a fork slides in with no resistance. Drain immediately and return the potatoes to the hot pot to remove any excess moisture.

Step 2: Infuse Warm Extra-Virgin Olive Oil with Aromatics

While the potatoes cook, warm the 0.5 cup Extra-Virgin Olive Oil in a small saucepan over low heat for 2 minutes. Add the 4 cloves Garlic Cloves and 1 tbsp Fresh Rosemary, then continue warming for another 2-3 minutes.

You want the garlic to become fragrant but not brown. The oil should take on a subtle golden hue and smell incredible. Remove from heat and let it steep while you finish the potatoes. This infusion adds layers of flavor that butter simply can’t match.

Step 3: Mash Potatoes with Infused Oil and Seasonings

Mash the drained potatoes in the pot using a potato masher or ricer. I prefer a ricer for ultra-smooth results, but a masher works too. Gradually drizzle in the warm Extra-Virgin Olive Oil mixture while continuing to mash.

Add the 0.25 cup Unsweetened Almond Milk, 1.5 tsp Sea Salt, and 0.5 tsp Freshly Ground Black Pepper. The almond milk should be warm—cold liquid can make the mashed potatoes gummy. Mash until just smooth with a few rustic lumps remaining for texture.

Step 4: Finish with Nutritional Yeast, Dijon, and Lemon

Stir in the 2 tbsp Nutritional Yeast, 1 tsp Dijon Mustard, and 1 tbsp Lemon Juice. The nutritional yeast adds a subtle cheesy depth that complements the olive oil beautifully.

The Dijon mustard balances the richness with a touch of tang, while the lemon juice brightens all the flavors. Taste and adjust the Sea Salt if needed. The texture should be creamy and luxurious, with the olive oil creating a silky finish that coats your spoon.

Step 5: Rest Briefly Before Serving

Let the mashed potatoes sit for 2-3 minutes before serving. This brief rest allows the flavors to meld together fully. Give them one final stir, check the consistency, and add a splash more warm Unsweetened Almond Milk if they seem too thick.

Serve immediately while warm. The result should be rich and satisfying, with the olive oil providing a velvety mouthfeel that makes you forget all about butter. The garlic and rosemary notes will be subtle but present in every bite.

Perfect Pairings for This Recipe

Protein Pairings

These mashed potatoes pair beautifully with herb-roasted chicken or garlic-marinated tofu. The olive oil base complements the natural flavors without overpowering them. I love serving them with a lemon-herb crust on baked chicken thighs. 🍗

Vegetable Sides

Balance the meal with steamed green beans or roasted Brussels sprouts. Their crisp texture contrasts nicely with the creamy potatoes. Toss the Brussels with 1 tbsp olive oil and 1 tsp sea salt before roasting at 400°F for 20 minutes.

Gravy Options

A mushroom gravy made with vegetable broth adds heartiness to this dish. Sauté 8 oz cremini mushrooms with 2 minced garlic cloves, then thicken with a cornstarch slurry. The earthy flavors complement the rosemary in the potatoes perfectly.

Bread Accompaniments

Serve with warm crusty bread or dinner rolls to soak up any extra olive oil. I recommend sourdough for its tangy contrast. Brush rolls with 1 tbsp olive oil and warm for 5 minutes in the oven.

Fresh Garnishes

Brighten the dish with chopped fresh parsley or chives. A sprinkle of smoked paprika adds color and a subtle smoky note. These garnishes add visual appeal and fresh flavors without dairy. ✨

Wine Pairing

A crisp Sauvignon Blanc or light Pinot Noir works well. The acidity cuts through the richness while complementing the garlic and rosemary. I prefer a New Zealand Sauvignon Blanc for its citrus notes. 🍷
