Side Dishes
This Argentinian sweet potato recipe transforms humble tubers into a smoky, chimichurri-kissed side dish with crispy edges that steal every plate. The secret lies in roasting sweet potatoes at high heat until caramelized, then finishing with a vibrant chimichurri that balances their natural sweetness with herby brightness.
I developed this after realizing how underrated sweet potatoes are in Argentinian cuisine—until now.
What sets this recipe apart is the chimichurri twist, a technique inspired by Argentina's love of bold, fresh herbs. While traditional puré de camote relies on simple mashed textures, this method elevates the dish with a restaurant-quality finish.
The sweet potatoes develop a deep caramelized crust while staying tender inside, and the chimichurri adds layers of flavor that cut through the richness.
The result is a side dish that's equally impressive as a main or accompaniment—think crispy, smoky sweet potatoes with herby chimichurri drizzled over the top. The combination of textures and flavors makes it perfect for family dinners or gatherings, especially when paired with grilled meats or a fresh salad.
Ready in just 45 minutes, this recipe delivers foolproof results with minimal effort. The chimichurri can be made ahead, and the roasting process is hands-off, making it ideal for busy weeknights. Let's get started!
Ingredients for argentinian sweet potato
Twelve ingredients transform ordinary sweet potatoes into a restaurant-quality Argentinian masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 1 ½ lb | Medium-sized, skin-on for crispiness |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | High-quality, fruity variety preferred |
| Smoked Paprika 🌶️ | 1 tbsp | For authentic smoky depth |
| Ground Cumin 🌿 | ½ tsp | Toasted for enhanced aroma |
| Fresh Parsley 🌿 | ½ cup | Finely chopped for chimichurri |
| Fresh Oregano 🌿 | ¼ cup | Dried oregano at 1/3 amount |
| Garlic Cloves 🧄 | 4 cloves | Peeled, minced for chimichurri |
| Red Wine Vinegar 🍷 | ¼ cup | Bold, dry variety preferred |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground for best flavor |
| Cayenne Pepper 🔥 | ¼ tsp | Adjust for desired heat level |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed for brightness |
The sweet potatoes are the foundation—look for vibrant orange flesh and firm, unblemished skins. Trader Joe's and Whole Foods carry excellent varieties like 'Beauregard' or 'Garnet,' which hold their shape beautifully during roasting. For the chimichurri, fresh herbs are non-negotiable—they deliver that signature bright, herby punch. Local farmers markets often have better quality than grocery stores, but if you're buying from a conventional supermarket, check the parsley and oregano stems for freshness. The garlic should be plump and firm, with no green shoots sprouting. Smoked paprika is essential for that authentic Argentinian smokiness—Penzeys or La Boîte brands offer excellent quality.
No smoked paprika? Substitute with 1/2 tsp liquid smoke plus 1 tsp regular paprika for depth. Fresh herbs unavailable? Dried oregano at one-third the amount works, but the texture will differ. For the vinegar, any bold, dry red wine vinegar works—Bragg or Balsamic Vinegar Co. are reliable options. The cayenne can be omitted entirely if you prefer a milder chimichurri. For the sweet potatoes, if you can't find medium-sized ones, cut larger potatoes into even 1.5-inch chunks. The chimichurri can be made 24 hours ahead—its flavors actually improve with time as the herbs mellow.
Roasted sweet potatoes keep well in the fridge for 4-5 days if stored in an airtight container, though they're best enjoyed within 2 days for maximum crispiness. The chimichurri will last 5-7 days refrigerated, but add a thin layer of olive oil before sealing to preserve freshness. For longer storage, freeze the chimichurri in ice cube trays—thaw and shake to re-emulsify before using. The roasted potatoes reheat beautifully in a 375°F oven for 10-15 minutes until crispy again. Portion the chimichurri into small jars for easy drizzling—it's perfect over grilled meats or salads too.

Step-by-step instructions for Argentinian sweet potato roast
Transform ordinary sweet potatoes into a restaurant-worthy dish with this smoky chimichurri technique.
Prep and Season the Sweet Potatoes
Preheat your oven to 425°F and line a large baking sheet with parchment paper. Peel the 1.5 lb sweet potatoes and cut them into 1-inch thick rounds, leaving the skin on for crispy edges. Arrange them in a single layer on the baking sheet, spacing them about ½ inch apart for even cooking.
In a small bowl, whisk together 1 tbsp smoked paprika, 0.5 tsp ground cumin, 1.5 tsp kosher salt, 0.5 tsp ground black pepper, and 0.25 tsp cayenne pepper. This spice blend is the soul of the dish—don't skip the cayenne, as it adds depth that complements the sweetness of the potatoes. Generously coat each sweet potato round with the spice mixture, pressing it into the flesh so it adheres well.
Roast Until Caramelized and Crispy
Drizzle the sweet potatoes evenly with 0.25 cup extra-virgin olive oil, using about 1 teaspoon per potato. This oil creates a protective layer that promotes browning and crispiness. Roast for 25-30 minutes, flipping them halfway through, until the edges are deep golden brown and the flesh is tender when pierced with a fork.
Here's the thing—you want the potatoes to caramelize, not burn. If they start browning too quickly, tent the baking sheet with foil for the last 5 minutes of cooking. The key is patience; crispy edges develop gradually, not instantly. Remove from the oven and let them rest for 5 minutes before serving—this ensures they stay crispy when sliced.
Prepare the Chimichurri Sauce
While the potatoes roast, finely chop 0.5 cup fresh parsley and 0.25 cup fresh oregano in a food processor or by hand with a sharp knife. Add the 4 minced garlic cloves and pulse until combined but still slightly textured. Transfer to a bowl and mix in 0.25 cup red wine vinegar and 2 tbsp lemon juice.
Slowly drizzle in 0.1 cup extra-virgin olive oil (reserving the rest for later) while whisking vigorously. The sauce should emulsify into a vibrant green paste with a bright, tangy flavor. Taste and adjust seasoning with additional salt or vinegar if needed. This chimichurri is the perfect foil to the smoky, crispy potatoes—its acidity cuts through the richness.
Finish and Serve with Crispy Perfection
Drizzle the remaining 0.15 cup extra-virgin olive oil over the roasted sweet potatoes and toss gently to coat. Spoon the chimichurri sauce over the top, allowing it to pool around the edges. The contrast of the bright green sauce against the caramelized potatoes is visually stunning and flavorfully balanced.
Serve immediately while the potatoes are still crispy. Each bite should deliver a satisfying crunch from the edges, a tender sweetness from the flesh, and a vibrant, herby finish from the chimichurri. For extra drama, garnish with additional fresh parsley and a sprinkle of flaky sea salt. This dish pairs beautifully with grilled meats or as a standalone vegetarian centerpiece.
Pro Tips For Making Argentinian Sweet Potato
- CUT THEM SMALL: Sweet potatoes take longer to cook than you’d think—especially when roasted. Dice them into 1-inch cubes, not chunks. I learned this the hard way when my first batch came out undercooked in the middle while the edges burned. Uniform size = even cooking.
- TOAST THE SPICES: Bloom your smoked paprika and cumin in the olive oil for 30 seconds before adding the potatoes. This wakes up their flavors and prevents a dull, one-note taste. (Yes, even if you’re impatient like me—just set a timer.)
- SALT THE POTATOES: Toss the diced sweet potatoes with a pinch of salt before roasting. It draws out moisture, helping them crisp up instead of steaming. Skip this, and you’ll end up with soft, sad edges—trust me.
- FINISH WITH ACID: Stir in a splash of lemon juice or vinegar at the end—just a teaspoon—while the potatoes are still hot. It brightens the earthy sweetness and cuts through the richness of the olive oil. (Sounds weird, but it works.)

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
While you can substitute regular potatoes, the flavor and texture will differ significantly. Sweet potatoes have a naturally sweeter, creamier texture that pairs beautifully with the smoky chimichurri. Regular potatoes will be starchier and less flavorful. If you must substitute, try yams for a closer texture, but expect a slightly different taste profile.
How do I make this recipe spicier?
For extra heat, increase the cayenne pepper to 1 teaspoon or add ½ teaspoon of red pepper flakes to the spice blend. You can also drizzle finished potatoes with a hot sauce or sprinkle with crushed chili flakes before serving. The chimichurri's acidity will help balance the spice beautifully.
Can I make this ahead of time?
Roast the sweet potatoes up to 2 days ahead and store them at room temperature in an airtight container. The chimichurri can be made 1 day ahead and stored in the fridge. Reheat the potatoes in a 375°F oven for 10-15 minutes until crispy again, then drizzle with fresh chimichurri before serving.
What's the best way to serve these?
These crispy sweet potatoes shine as a side dish with grilled meats like flank steak or chorizo, but they're also perfect as a vegetarian main. Serve with a simple green salad and a glass of Argentinian Malbec or ice-cold yerba mate for the full experience. The chimichurri also makes an excellent marinade for grilled chicken!
Why did my sweet potatoes turn mushy?
Mushy sweet potatoes usually happen from overcooking or cutting them too thin. For perfect texture, cut them into 1-inch thick rounds and roast at 425°F for 25-30 minutes. If they're still soft, they likely need more time in the oven. The key is high heat and patience—don't rush the cooking process!
