Ingredients for argentina potato salad
Six ingredients transform ordinary potatoes into Argentina's boldest side dish—crispy, smoky, and full of herby brightness!
| Ingredient | Amount | Notes |
|---|---|---|
| Yukon Gold Potatoes 🥔 | 3 lb | Cut into 2-inch chunks, crispy-skinned |
| Extra-Virgin Olive Oil 🫒 | ½ cup | For roasting and dressing |
| Mayonnaise 🥫 | ¾ cup | Duck or regular brand preferred |
| Yellow Mustard 🌶️ | 2 tbsp | For tangy depth |
| Red Wine Vinegar 🍷 | 2 tbsp | Argentinian preferred |
| Fresh Parsley 🌿 | ½ cup | Chopped finely for chimichurri |
| Garlic Cloves 🧄 | 4 cloves | Minced for chimichurri |
| Red Chili Flakes 🌶️ | 1 tsp | For smoky heat |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Hard-Boiled Eggs 🥚 | 4 whole | Optional protein boost |
| Canned Tuna 🐟 | 1 can | Optional protein addition |
The potatoes are the star—Yukon Golds are perfect for their creamy texture and crispy skins. Trader Joe's or local farmers markets usually have them in season. Cut them into even 2-inch chunks so they roast uniformly. If you can't find Yukon Golds, Russets work too—just roast them a few minutes longer. The key to crispy skins? Roast them at 425°F until golden and tender. I always double-check the oven temp with an instant-read thermometer—425°F is non-negotiable for that perfect texture.
No chimichurri? Fresh parsley is non-negotiable—it's the heart of this dish. If you're out, cilantro works in a pinch, but it changes the flavor profile. The red wine vinegar adds that signature tang, so don't skip it. For the mayo, Duck brand is ideal—it's richer and stands up to the bold flavors, but regular mayo works too. The tuna and eggs are optional but add a nice protein boost. If you're making this ahead, hold off on adding them until serving so they stay fresh. The salad actually tastes better the next day—flavors meld beautifully!
Roasted potatoes keep for 3-4 days in the fridge, but the chimichurri is best made fresh. Store it in a jar with a splash of olive oil on top to keep it vibrant. The whole salad holds up for 4-5 days if stored properly—portion it into containers so you can grab it straight from the fridge. For extra crispiness, reheat the potatoes in the oven for 10 minutes at 400°F before serving. This is the kind of dish that gets better as it sits, so make a big batch—it disappears fast at gatherings!

Step-by-step instructions for Argentina potato salad recipe
Here's how to create that perfect balance of crispy-skinned potatoes and smoky chimichurri goodness.
🔥 Step 1: Roast Potatoes Until Crispy
Preheat your oven to 425°F and line two rimmed baking sheets with parchment paper. Toss the 3 lb Yukon Gold Potatoes (cut into 2-inch chunks) with 0.25 cup of the extra-virgin olive oil and 1 tsp Salt. Spread them in a single layer, making sure they don't overlap.
Roast for 30 minutes, then flip each piece using tongs. Roast another 20-25 minutes until the edges are deep golden brown and the skin is crispy. The potatoes should feel firm to the touch but still tender inside. If they're browning too quickly, move them to a lower oven rack.
👨🍳 Step 2: Make the Smoky Chimichurri Dressing
While the potatoes roast, pulse the 4 cloves Garlic Cloves, 0.5 cup Fresh Parsley, 1 tsp Red Chili Flakes, 0.5 tsp Black Pepper, and 1.5 tsp Salt in a food processor until finely chopped. With the motor running, slowly drizzle in the remaining 0.25 cup extra-virgin olive oil until the mixture forms a coarse paste.
Transfer to a bowl and stir in the 2 tbsp Red Wine Vinegar and 2 tbsp Yellow Mustard. Taste and adjust seasoning—this is your flavor foundation. The chimichurri should be vibrant green with a smoky, garlicky aroma. If it's too thick, add 1-2 tsp water to loosen it.
🥘 Step 3: Mix Dressing with Warm Potatoes
Let the roasted potatoes cool slightly for 5 minutes (they'll be piping hot). In a large bowl, combine the potatoes with the chimichurri dressing, tossing gently to coat evenly. The potatoes should absorb the dressing but still retain their crispy edges. If they seem dry, add 1-2 tbsp extra-virgin olive oil to help distribute the dressing.
Gently fold in the 4 whole Hard-Boiled Eggs, quartered lengthwise, and the 1 can Canned Tuna (drained and flaked). The tuna adds a nice protein boost while keeping the dish light. Taste and adjust seasoning one final time—this is where all the flavors come together.
⏰ Step 4: Chill and Serve for Maximum Flavor
Transfer the potato salad to a serving bowl and refrigerate for at least 30 minutes (or up to 4 hours). Chilling allows the flavors to meld beautifully and the crispy skin to firm up slightly. Before serving, give it a final toss to redistribute any dressing that may have settled.
Serve the salad at room temperature, garnished with extra chimichurri and a sprinkle of fresh parsley. The contrast of crispy potato skins, creamy chimichurri, and cool eggs makes this dish incredibly satisfying. Pair it with grilled meats or crusty bread for the ultimate Argentine-inspired meal.
Pro Tips For Making Argentina Potato Salad
- COOL THE POTATOES FIRST: I learned this the hard way—straight-from-the-boiler Yukon Golds turn your salad into a gluey mess. Run them under cold water for 30 seconds immediately after cooking, then let them sit in an ice bath for 10 minutes. This keeps their texture firm and creamy, not mushy. (Yes, even if you're impatient like me.)
- USE THE RIGHT OIL RATIO: Extra-virgin olive oil is non-negotiable here, but don’t drown the potatoes. For every 2 cups of cooked Yukon Golds, use 2 tablespoons of oil—just enough to coat the cut sides. Too much, and the salad tastes like a dressing; too little, and it’ll dry out. Taste as you go.
- DON’T SKIP THE VINEGAR REST: Mix the mayo, mustard, and red wine vinegar at least 15 minutes before adding to the potatoes. This lets the acid mellow out, so the dressing doesn’t taste sharp or separate later. (I know, I know—waiting is hard, but your salad will thank you.)
- CUT POTATOES UNIFORMLY: Big chunks? They’ll stay cold. Tiny dice? They’ll turn to mush. Aim for 1-inch cubes—consistent size means even cooking and a salad that holds together. A sharp knife and a steady hand make this easier than it sounds. (No, a potato slicer won’t cut it here.)
Flavor customization for these flavors
Smoky Heat Level
Adjust the heat to your taste by controlling the red chili flakes. For a mild version, reduce to just ½ tsp—this still adds subtle warmth without overpowering. If you love bold flavors, add 1½ tsp and a pinch of smoked paprika for deeper complexity.
I often test the chimichurri first before mixing it with the potatoes to ensure the balance is right. 🌶️
Herb Variations
Swap out parsley for cilantro if you prefer a citrusy note, but reduce the amount to ¼ cup since it's more potent. For a Mediterranean twist, add 1 tbsp fresh oregano or thyme to the chimichurri.
My grandmother used to mix in 1 tsp dried oregano when fresh herbs were scarce—it still worked beautifully!
Protein Swaps
Skip the eggs and tuna for a vegetarian version, but add ½ cup diced roasted red peppers or ¼ cup chopped Kalamata olives for briny contrast. For extra protein, fold in ½ cup cooked chorizo (crumbled) or ½ cup grilled chicken breast (chilled and diced).
The key is to keep proteins cool until mixing to avoid soggy potatoes. 🥚
Dressing Depth
Boost the dressing with 1 tsp honey for a touch of sweetness that balances the acidity. For a tangier profile, add 1 tbsp lemon juice instead of some of the vinegar.
I sometimes mix in 1 tsp Dijon mustard for extra depth—it adds a subtle complexity that elevates the whole dish. Always taste as you go!
Texture Contrast
Add crunch with ¼ cup toasted breadcrumbs or 2 tbsp chopped walnuts mixed in just before serving. For extra richness, fold in ¼ cup crumbled feta cheese (if you're open to a Greek-Argentinian fusion). The contrast of crispy skins, creamy dressing, and crunchy toppings makes every bite exciting. 🌟
Regional Twists
For a Patagonian-inspired version, add ¼ cup diced pickled onions and a dash of hot sauce. In Buenos Aires, vendors often include diced ham or cornichons for a French-Argentinian fusion.
I once tried adding sliced green olives and red onion rings—it was a hit at my summer potluck! 🗺️

Frequently asked questions
Can I use regular potatoes instead of Yukon Golds?
Yes, but the texture will differ. Russets will give you fluffier insides but less crispy skins. For best results, roast them 5-10 minutes longer at 425°F and toss with an extra 1 tbsp olive oil before roasting. Red potatoes work too—they stay firmer and hold their shape beautifully. Just reduce roasting time by 5 minutes to avoid overcooking.
How do I make this recipe vegetarian?
Skip the eggs and tuna, then add ½ cup diced roasted red peppers or ¼ cup chopped Kalamata olives for briny contrast. For extra protein, fold in ½ cup cooked chickpeas (chilled) or ¼ cup crumbled feta cheese. The key is to keep all add-ins cool until mixing to maintain that perfect crispy texture.
Can I make the chimichurri ahead of time?
Make the chimichurri up to 2 days ahead and store it in an airtight container with a splash of olive oil on top. The flavors actually deepen over time. Just give it a quick stir before using. For the potatoes, roast them fresh or reheat stored roasted potatoes in the oven at 375°F for 10 minutes to restore crispiness before mixing.
Why does my potato salad get watery?
Overmixing warm potatoes releases starch, which creates a gummy texture. Always let potatoes cool 5 minutes before mixing, and use room-temperature dressing. For extra insurance, pat potatoes dry with a paper towel before tossing. If it still seems too wet, add 1 tbsp extra-virgin olive oil to help absorb moisture. Chill for at least 30 minutes before serving.
What's the best way to store leftovers?
Store in an airtight container for up to 4-5 days in the fridge. For best texture, portion into individual containers so you can grab just what you need. If reheating, warm potatoes alone in the oven at 350°F for 15 minutes before serving. The chimichurri and proteins stay fresh best when stored separately—mix everything together just before serving for maximum crispiness.
