How to Make Spanish Garlic Sweet Potatoes | Boniatos al Ajillo Recipe
Step 1: Prep and Rinse the Sweet Potatoes
Begin by peeling and slicing your sweet potatoes into 1/4 inch thick rounds. This thickness helps them cook evenly, ensuring a tender inside and slightly crisp edges. Once sliced, rinse the potatoes under cold water until the water runs clear. This step removes excess starch, which helps achieve that perfect sauté without sticking. Then, pat the slices completely dry on a dishcloth to prepare them for frying.
Step 2: Heat the Olive Oil and Fry the Sweet Potatoes
Warm a large frying pan over medium heat and pour in the full cup of extra virgin olive oil. As the oil heats, carefully add the sweet potato slices, making sure each piece is well coated. Sauté the potatoes for 20 to 25 minutes, stirring every 2 to 3 minutes so they brown evenly without burning. The goal is to get them lightly golden and cooked through—check by piercing with a toothpick for that perfect tenderness.
Step 3: Prepare the Garlic Parsley Sauce
While the potatoes are frying, take 2 cloves of garlic and roughly chop them. Place these into a mortar with the chopped parsley and a pinch of salt, then use a pestle to mash everything into a fragrant, well-combined paste. Slowly add 2 tablespoons of extra virgin olive oil to this mixture and stir thoroughly. This garlicky sauce will be your finishing touch, bringing a vibrant note to the dish.
Step 4: Strain and Refresh the Olive Oil
Once the potatoes are cooked, gently remove them from the pan and set aside. Pour the olive oil through a fine sieve into a heatproof bowl; this filters out bits and makes the oil cleaner for the next steps and future use. Return the pan to medium heat, adding 2 tablespoons of the strained olive oil back into it to prepare for sautéing the remaining garlic.
Step 5: Sauté the Garlic and Combine
Add the remaining 6 cloves of roughly chopped garlic to the hot oil and stir continuously for 1 to 2 minutes until fragrant and lightly golden. Immediately add the cooked sweet potatoes back to the pan. Season generously with sea salt and black pepper, then gently toss to ensure every piece is coated in that vibrant garlic-infused oil.
Step 6: Serve with Garlic Parsley Sauce
Transfer the beautiful golden sweet potatoes to a large serving dish. Pour over the garlic and parsley sauce you prepared earlier, letting it drizzle lovingly across the potatoes. This is the moment when all the bold, fresh flavors come together to create the irresistible dish that is Spanish Garlic Sweet Potatoes | Boniatos al Ajillo Recipe. Dig in and enjoy!
How to Serve Spanish Garlic Sweet Potatoes | Boniatos al Ajillo Recipe
Garnishes
Freshness is key for balancing the richness of this dish. Sprinkle a little extra chopped parsley or even some finely diced green onions on top just before serving to add a pop of color and freshness. A light squeeze of lemon juice can also brighten the flavors if you want a zesty uplift.
Side Dishes
Spanish Garlic Sweet Potatoes are incredibly versatile and pair beautifully alongside many main courses. Think grilled seafood, roasted chicken, or even a simple green salad for lighter fare. Their hearty yet bright profile also complements rustic stews and tapas-style spreads perfectly.
Creative Ways to Present
Want to impress your guests? Try layering the sweet potatoes in a shallow terracotta dish, just like a traditional Spanish cazuela, and drizzle the garlic parsley sauce in an artistic zigzag pattern. You can also serve the potatoes on warm toasted bread as a tapas-style snack topped with a sprinkle of smoked paprika for an extra kick.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, store them in an airtight container in the refrigerator. The sweet potatoes keep well for up to 3 days and retain their lovely texture and flavor when properly cooled.
Freezing
For longer storage, you can freeze the cooked sweet potatoes. Flash freeze them on a baking sheet first so they don’t stick together, then transfer to freezer-safe bags. They’ll stay good for up to 2 months. Just note that the texture might soften slightly upon thawing.
Reheating
To reheat, place the sweet potatoes in a warm oven or skillet to regain some crispness, avoiding the microwave if possible, which can make them mushy. Gently warm and add a fresh drizzle of olive oil or the garlic parsley sauce to revive that fresh flavor.
FAQs
Can I use regular sweet potatoes instead of boniatos?
Yes, regular orange-fleshed sweet potatoes work well, but boniatos have a slightly different texture and a sweeter, drier flavor that is traditional in this recipe.
Is there a substitute for the extra virgin olive oil?
Extra virgin olive oil is key for its flavor and health benefits, but if you need a substitute, a good quality mild-flavored oil like avocado oil can work in a pinch.
Can this dish be made vegan?
Absolutely! This recipe is naturally vegan since it uses plant-based ingredients. It’s a perfect dish for vegan and vegetarian diets.
How do I know when the sweet potatoes are done cooking?
The sweet potatoes should be lightly golden and tender enough to pierce easily with a toothpick or fork. This usually takes about 20 to 25 minutes on medium heat.
Can I add other herbs or spices?
Definitely! While parsley is classic, feel free to add rosemary, thyme, or even a pinch of smoked paprika to experiment with flavor variations.

Golden and lightly crispy, these sweet potatoes are infused with rich garlic flavors, making them a perfect appetizer or side dish to complement any meal.
Ingredients
Sweet Potatoes
- 3 sweet potatoes (peeled), 1.5 lbs. / 700 grams
Cooking Oil and Garlic
- 1 cup extra virgin olive oil, 240 ml
- 8 cloves garlic (roughly chopped)
Garlic Parsley Sauce
- 2 tbsp chopped parsley, 5 grams
- 2 tbsp extra virgin olive oil, 30 ml
- Sea salt & black pepper, to taste
Instructions
- Prepare the Oil: Heat a large frying pan over medium heat and add 1 cup (240 ml) of extra virgin olive oil. Allow the oil to warm up until hot but not smoking.
- Slice and Rinse Sweet Potatoes: Cut the peeled sweet potatoes into rounds about 1/4 inch (0.625 cm) thick. Place the sliced sweet potatoes in a large bowl, rinse under cold water for approximately 1 minute or until the water runs clear to remove excess starch. Drain and pat dry thoroughly with a clean dishcloth.
- Sauté Sweet Potatoes: Carefully add the sliced sweet potatoes into the hot olive oil in the pan. Gently toss to coat each slice evenly with oil. Cook them, stirring every 2 to 3 minutes to ensure even frying and prevent sticking, for about 20 to 25 minutes until lightly golden and cooked through. Test doneness by piercing with a toothpick.
- Prepare the Garlic Parsley Sauce: Meanwhile, place 2 cloves of roughly chopped garlic, 2 tbsp chopped parsley, and a pinch of sea salt into a mortar. Use a pestle to mash and combine the ingredients thoroughly. Stir in 2 tbsp (30 ml) extra virgin olive oil until well mixed to form a fragrant garlic and parsley sauce.
- Drain the Oil: Once the sweet potatoes are cooked, carefully remove them with a slotted spoon and set aside on a plate. Pour the used olive oil from the pan through a fine sieve into a heatproof bowl to strain out garlic bits and impurities. This filtered oil can be reused for future cooking.
- Sauté Remaining Garlic: Return the frying pan to medium heat and add 2 tbsp (30 ml) of the strained olive oil. Immediately add the remaining 6 cloves of roughly chopped garlic and sauté continuously for 1 to 2 minutes until fragrant and lightly golden, taking care not to burn the garlic.
- Combine Sweet Potatoes and Season: Return the cooked sweet potatoes to the pan with the garlic. Season with sea salt and black pepper to taste, and gently toss everything together to evenly coat the potatoes with the garlic and oil mixture.
- Serve: Transfer the garlic-infused sweet potatoes to a large serving dish. Spoon over the previously prepared garlic parsley sauce. Serve immediately and enjoy this flavorful Spanish appetizer or side dish.
Notes
