Chimichurri Lentil Stuffed Sweet Potatoes: An Argentinian-Inspired Plant-Based Dinner
As I keep expanding the recipes on my site and trying out new flavors from different countries, I realized I had not yet shared anything inspired by South America. I spent about a year traveling there, and Argentina quickly became one of my favorite places—especially because I fell in love with their food. For this recipe, I wanted to highlight chimichurri, which is such an important part of Argentine cooking, and that’s how these Chimichurri Lentil Stuffed Sweet Potatoes were born. Pairing the vibrant sauce with hearty lentils and sweet roasted potatoes just felt right. The result is flavorful, satisfying, and easy to prep ahead so everything comes together smoothly once the sweet potatoes are out of the oven.

What Is Chimichurri?
Chimichurri is a traditional Argentine sauce made with parsley, garlic, olive oil, vinegar, and chili flakes. It’s fresh, tangy, and a little spicy, and it’s often served with grilled meats as the ultimate condiment. Unlike cooked sauces, chimichurri is always prepared raw, which keeps the flavors bright and vibrant. While it’s most commonly paired with steak in Argentina, it’s just as delicious on vegetables, grains, or even bread—making it an easy way to bring bold flavor to plant-based dishes.
Ingredient Highlight: Sweet Potatoes
Sweet potatoes are the foundation here, bringing natural sweetness and a soft, creamy texture that balances the smoky lentils and zesty chimichurri. They’re not only delicious but also loaded with fiber, beta-carotene, and vitamin C, making them as nourishing as they are versatile. Roasting them cut-side down concentrates their flavor and gives you that perfect, caramelized surface.
Madly Delicious Must-Know Tips & Questions
Prep ahead. You can make the chimichurri, lentil filling, and pickled onions a day or two in advance. When ready to serve, all you need to do is roast the sweet potatoes and assemble.
Choose your lentils wisely. French green lentils (or brown lentils) hold their shape best here. Red lentils will turn mushy and don’t work as well for this dish.
Make it a meal. While this works as a main course on its own, you can also serve it with a side salad, roasted veggies, or even warm flatbread to round out the meal.
What kind of sweet potato should I use?
Any variety works, but the flavor will vary. Orange-fleshed sweet potatoes are sweeter and softer, while white varieties (like Japanese or Cilembu) are drier and more chestnut-like. Choose whichever suits your taste!
Can I make this ahead?
Yes. Roast the sweet potatoes and prepare the lentils and chimichurri in advance. Assemble when ready to serve, and reheat the potatoes if needed.
Let’s Dish About Chimichurri: Did You Know?
Argentine cuisine is shaped by waves of immigration, and chimichurri is a great example of that fusion. Its roots are believed to trace back to Basque settlers, who brought herb-and-vinegar sauces that blended with local ingredients and Spanish cooking traditions. Today, chimichurri varies by region—some versions use oregano heavily, others add chili for heat, and coastal areas sometimes lighten it with more vinegar. No matter the variation, it’s become one of Argentina’s most iconic sauces.

- Optional garnish: pickled red onions
Lentil Filling
- ½ cup dry green (French lentils preferred; ~1¼ cups cooked)
- 2 tbsp olive oil
- ½ red onion, diced
- ½ red bell pepper, diced
- 2 cloves garlic, minced
- 1 tsp smoked paprika
- Salt, to taste
- Black pepper, to taste

Chimichurri
- ½ cup parsley, finely chopped
- 2 garlic cloves, grated or finely minced
- 1½ tbsp red wine vinegar
- ½ tsp dried oregano
- ¼-½ tsp red chili flakes
- ¼ tsp salt
- ⅓ cup olive oil
Instructions
- Preheat the oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or lightly grease.
- Cook the lentils: Rinse ½ cup dry green lentils under cold water. Place in a saucepan with 1½ cups water and a pinch of salt. Bring to a boil, then reduce heat and simmer until tender but not mushy, 20–25 minutes. Drain and set aside.
- Prepare the sweet potatoes: Cut the sweet potatoes in half lengthwise. Rub each half with olive oil, salt, and pepper. Place cut-side down on the baking sheet and bake for 30–40 minutes, until fork tender. Cook time varies based on type of sweet potato.
- Make the chimichurri: In a small bowl, combine ½ cup finely chopped parsley, 2 grated garlic cloves, 1½ tbsp red wine vinegar, ½ tsp oregano, ¼–½ tsp red chili flakes, and ¼ tsp salt. Drizzle in ⅓ cup olive oil until well mixed. Taste and adjust seasoning if needed.
- Cook the lentil filling: Heat 2 tbsp olive oil in a skillet over medium heat. Add ½ diced red onion and ½ diced red bell pepper. Sauté 4–5 minutes until softened. Stir in 2 minced garlic cloves and 1 tsp smoked paprika; cook 1 minute more. Add the cooked lentils and season with salt and pepper to taste. Stir well, adjust seasoning as needed, and finish with a splash of red wine vinegar for brightness.
- Assemble and serve: Once done cooking, flip the roasted sweet potato halves cut-side up and gently mash the flesh with a fork to open them slightly. Spoon the lentil mixture evenly into each half. Drizzle generously with chimichurri and garnish with pickled onions, if desired.
