Ingredients You’ll Need

To make Crispy Smashed Sweet Potatoes with Vegan Garlic Aioli, you’ll need the following ingredients. Don’t worry—most of these are pantry staples!

For the Crispy Smashed Sweet Potatoes:

4 medium sweet potatoes (about 1.5 lbs or 700g)
2 tablespoons olive oil (or avocado oil for a higher smoke point)
1 teaspoon sea salt (plus more to taste)
½ teaspoon black pepper
1 teaspoon smoked paprika (optional, for extra flavor)
1 teaspoon garlic powder
½ teaspoon onion powder
Fresh parsley or chives (for garnish)

For the Vegan Garlic Aioli:

½ cup vegan mayonnaise (store-bought or homemade)
2 cloves garlic, minced (or 1 teaspoon garlic powder in a pinch)
1 tablespoon lemon juice (freshly squeezed for best flavor)
1 teaspoon Dijon mustard (optional, for a little tang)
½ teaspoon maple syrup or agave nectar (to balance the flavors)
¼ teaspoon sea salt (plus more to taste)
¼ teaspoon black pepper
1-2 tablespoons unsweetened almond milk or water (to thin if needed)

Step-by-Step Instructions

Step 1: Cook the Sweet Potatoes

Start by preheating your oven to 400°F (200°C). Line a baking sheet with parchment paper or a silicone baking mat for easy cleanup.

Wash and scrub the sweet potatoes thoroughly to remove any dirt. Pierce each potato a few times with a fork to allow steam to escape during cooking. Place the sweet potatoes on the prepared baking sheet and bake for 45-60 minutes, or until they are tender and easily pierced with a fork. The cooking time will depend on the size of your potatoes.

Alternatively, you can cook the sweet potatoes in the microwave to save time. Place them on a microwave-safe plate and cook on high for 8-12 minutes, turning halfway through. This method is faster but may result in slightly less caramelization.

Step 2: Smashed the Sweet Potatoes

Once the sweet potatoes are cooked and slightly cooled, it’s time to smash them! Using the bottom of a glass, a fork, or a potato masher, gently press down on each sweet potato until it flattens and cracks open. Be careful not to smash them too thin, or they may burn in the oven. Aim for a thickness of about ½ inch (1.25 cm).

Transfer the smashed sweet potatoes back to the baking sheet. Drizzle them with olive oil and sprinkle with salt, black pepper, smoked paprika, garlic powder, and onion powder. Use your hands or a brush to ensure the potatoes are evenly coated with the oil and spices.

Step 3: Roast Until Crispy

Return the baking sheet to the oven and roast the smashed sweet potatoes for 20-25 minutes, or until the edges are golden brown and crispy. For extra crispiness, you can broil them for 2-3 minutes at the end, but keep a close eye on them to prevent burning.

Once done, remove the sweet potatoes from the oven and let them cool slightly. Garnish with fresh parsley or chives for a pop of color and freshness.

Step 4: Make the Vegan Garlic Aioli

While the sweet potatoes are roasting, prepare the vegan garlic aioli. In a small bowl, combine the vegan mayonnaise, minced garlic, lemon juice, Dijon mustard, maple syrup, salt, and black pepper. Whisk everything together until smooth and well combined.

If the aioli is too thick, add 1-2 tablespoons of almond milk or water to thin it out to your desired consistency. Taste and adjust the seasoning as needed—add more salt, lemon juice, or garlic if desired.

Transfer the aioli to a serving bowl and garnish with a sprinkle of smoked paprika or fresh herbs for an extra touch of flavor.

Step 5: Serve and Enjoy!

Arrange the crispy smashed sweet potatoes on a platter and serve them with the vegan garlic aioli on the side. For an extra special presentation, drizzle some aioli over the top of the potatoes or serve it in a small bowl for dipping.

These smashed sweet potatoes are best enjoyed fresh out of the oven, but they can also be reheated in the oven or air fryer if you have leftovers. Simply warm them at 350°F (175°C) for 5-10 minutes until heated through.

Tips for the Best Crispy Smashed Sweet Potatoes

Want to take your smashed sweet potatoes to the next level? Here are some expert tips to ensure they turn out perfectly every time:

1. Choose the Right Sweet Potatoes

Not all sweet potatoes are created equal! For this recipe, opt for medium-sized sweet potatoes with smooth, firm skin. Avoid potatoes that are too large, as they may take longer to cook and could become mushy when smashed. Japanese or Hannah sweet potatoes are great choices because they have a slightly drier texture, which helps them crisp up better in the oven.

2. Don’t Skip the Parchment Paper

Using parchment paper or a silicone baking mat is key to preventing the sweet potatoes from sticking to the baking sheet. It also makes cleanup a breeze! If you don’t have parchment paper, lightly grease the baking sheet with oil, but be aware that the potatoes may stick slightly.

3. Smash Gently for the Best Texture

When smashing the sweet potatoes, aim for a rustic, uneven texture rather than a perfectly flat surface. This creates more edges and crevices, which crisp up beautifully in the oven. Press down just enough to flatten the potatoes, but leave some chunks for added texture.

4. Use High Heat for Maximum Crispiness

Roasting the sweet potatoes at a high temperature (400°F/200°C or higher) is essential for achieving that coveted crispy exterior. If your oven runs cool, consider increasing the temperature slightly or broiling for the last few minutes to get that golden-brown finish.

5. Don’t Overcrowd the Baking Sheet

Give the smashed sweet potatoes plenty of space on the baking sheet to ensure even cooking and crispiness. Overcrowding can cause steam to build up, resulting in soggy potatoes instead of crispy ones. If necessary, use two baking sheets or cook the potatoes in batches.

6. Experiment with Seasonings

While the basic seasoning of salt, pepper, and garlic powder is delicious, don’t be afraid to get creative! Try adding cumin, chili powder, or rosemary for a different flavor profile. You can also sprinkle the potatoes with nutritional yeast before roasting for a cheesy, umami boost.

7. Make the Aioli Ahead of Time

The vegan garlic aioli can be made up to 3 days in advance and stored in an airtight container in the refrigerator. This allows the flavors to meld together, resulting in an even tastier dip. Just give it a good stir before serving, as the ingredients may separate slightly.

The Health Benefits of Sweet Potatoes

Sweet potatoes aren’t just delicious—they’re also incredibly nutritious! Here are some of the top health benefits of incorporating sweet potatoes into your diet:

1. Rich in Vitamins and Minerals

Sweet potatoes are an excellent source of vitamin A (in the form of beta-carotene), which is essential for healthy vision, immune function, and skin health. They’re also high in vitamin C, which supports collagen production and immune health, and potassium, which helps regulate blood pressure and muscle function.

2. High in Fiber

A medium sweet potato contains about 4 grams of fiber, which aids in digestion, promotes feelings of fullness, and helps stabilize blood sugar levels. The fiber in sweet potatoes also supports a healthy gut microbiome.

3. Packed with Antioxidants

Sweet potatoes are loaded with antioxidants, including beta-carotene, anthocyanins (in purple sweet potatoes), and chlorogenic acid. These compounds help protect your cells from damage caused by free radicals, reducing the risk of chronic diseases like heart disease and cancer.

4. Supports Blood Sugar Regulation

Despite their sweet taste, sweet potatoes have a low glycemic index (GI), meaning they cause a slower, more gradual rise in blood sugar levels compared to high-GI foods. This makes them a great option for people with diabetes or those looking to manage their blood sugar levels.

5. Anti-Inflammatory Properties

The antioxidants and anti-inflammatory compounds in sweet potatoes can help reduce inflammation in the body, which is linked to a variety of chronic diseases, including arthritis, heart disease, and obesity.

Frequently Asked Questions (FAQs)

1. Can I make this recipe ahead of time?

Yes! You can boil or microwave the sweet potatoes ahead of time and store them in the refrigerator for up to 2 days. When you’re ready to serve, smash them, season, and roast as directed. The vegan garlic aioli can also be made ahead of time and stored in the refrigerator for up to 3 days.

2. How do I reheat leftover smashed sweet potatoes?

To reheat leftover smashed sweet potatoes, place them on a baking sheet and warm them in the oven at 350°F (175°C) for 5-10 minutes, or until heated through. You can also reheat them in the air fryer at 350°F (175°C) for 3-5 minutes for extra crispiness. Avoid microwaving, as this can make them soggy.

3. Can I use regular potatoes instead of sweet potatoes?

Absolutely! While sweet potatoes add a natural sweetness and unique flavor, you can use regular potatoes (such as Yukon Gold or russet potatoes) for a more savory version of this dish. The cooking time may vary slightly, so keep an eye on them to prevent burning.

4. How can I make this recipe oil-free?

If you prefer to avoid oil, you can omit the olive oil when roasting the sweet potatoes. Instead, mist them lightly with water or vegetable broth before seasoning. You can also use an air fryer to achieve crispiness without oil. For the aioli, use an oil-free vegan mayonnaise or make your own using soaked cashews or silken tofu.

5. What can I use instead of vegan mayonnaise for the aioli?

If you don’t have vegan mayonnaise on hand, you can make the aioli using one of the following substitutes:

Cashew cream: Blend soaked cashews with water, garlic, lemon juice, and salt until smooth.
Silken tofu: Blend silken tofu with garlic, lemon juice, Dijon mustard, and salt until creamy.
Vegan yogurt: Use unsweetened vegan yogurt (such as coconut or almond yogurt) as the base for the aioli.
Avocado: Mash ripe avocado with garlic, lemon juice, and salt for a creamy, oil-free dip.
