Description
Crispy smashed fingerling potatoes served with garlic parmesan aioli, perfect as a side dish or appetizer.
Ingredients
- 24 oz (680 g) fingerling potatoes, small and thin-skinned, firm to touch
- 3 tablespoons (45 ml) extra virgin olive oil
- 3/4 teaspoon (4.5 ml) fine sea salt
- 3/4 teaspoon (4.5 ml) black pepper
- 2 teaspoons (10 ml) fresh thyme, finely minced
- Garlic, fresh cloves (amount per your aioli recipe)
- Parmesan cheese (amount per your aioli recipe)
- Mayonnaise (amount per your aioli recipe)
- Lemon juice, fresh (amount per your aioli recipe)
- Fresh herbs like parsley or chives, chopped (optional for garnish)
Instructions
- Step 1: Fill a large saucepan with cold water and add a generous pinch of salt. Place the fingerling potatoes in the water. Bring to a boil over medium-high heat and boil for 20 minutes until the potatoes are fork-tender but not mushy.

- Step 2: Drain the potatoes carefully and spread them out on a clean kitchen towel. Pat them dry thoroughly to remove excess moisture. This step is crucial to achieve a crispy finish during roasting.

- Step 3: Set your oven to 450°F (232°C). Line a rimmed baking sheet with parchment paper or a silicone baking mat for easy cleanup.

- Step 4: In a mixing bowl, toss the dried potatoes with 3 tablespoons olive oil, 3/4 teaspoon fine sea salt, 3/4 teaspoon black pepper, and 2 teaspoons fresh thyme. Toss thoroughly to coat every potato evenly.

- Step 5: Place the seasoned potatoes in a single layer on the prepared baking sheet. Leave some space between each potato to allow air circulation, which is essential for even crisping.

- Step 6: Spray or drizzle the bottom of a flat-bottomed glass, mason jar, or measuring cup with non-stick spray or olive oil. Place the glass over each potato and apply gentle pressure to smash them down to approximately 1/4 inch (0.6 cm) thickness. The wider the smash, the more crispy edges will form.

- Step 7: Roast the smashed potatoes at 450°F (232°C) for 20-25 minutes. Flip or rotate the pan halfway through cooking, around 15 minutes, to promote even browning. Potatoes are done when edges are golden brown and crispy.

- Step 8: Serve the smashed fingerling potatoes hot with garlic parmesan aioli or a yogurt-based dip of your choice. Garnish with fresh herbs such as parsley or chives if desired.

Notes
- Room Temperature: Store cooled potatoes in an airtight container at room temperature away from direct sunlight for up to 2 days.
- Refrigeration: Place potatoes in an airtight container and refrigerate for up to 4 days. Ensure potatoes are completely cooled before sealing and refrigerating.
- Freezing: Wrap potatoes tightly in plastic wrap and place them in a freezer bag. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
- Patting the potatoes completely dry after boiling prevents sogginess and helps achieve the crispy texture during roasting.
- Use a stable, flat-bottomed glass or jar to apply even pressure when smashing potatoes to avoid breaking them apart.
- Rotate the baking sheet halfway through roasting if potatoes are not browning evenly to ensure consistent crispiness.
- Taste potatoes immediately after smashing and sprinkle additional fine sea salt if needed; the heat helps seasoning adhere better.
- Check potatoes for fork tenderness after 15 minutes boiling to avoid overcooking and mushiness.

Ingredient Notes
- Fingerling potatoes: Look for small, thin-skinned ones that feel firm to the touch. Their unique shape gives you great texture when smashed.
- Garlic: Fresh garlic cloves work best. Avoid pre-minced varieties; the flavor is way better when you chop it yourself. It enhances the aioli beautifully.
- Olive oil: A good-quality extra virgin olive oil enriches the aioli and adds depth. Don’t skimp; it makes a huge difference in flavor.
- Mayonnaise: Use a flavorful, creamy mayonnaise as the base for the aioli. It creates a smooth texture and binds all the flavors together. You can swap it with Greek yogurt for a lighter version.
- Lemon juice: Opt for fresh lemon juice to brighten the aioli and balance the richness. Bottled juice doesn’t pack the same punch.
- Fresh herbs: Chopped parsley or chives are great additions. They add freshness and color, making the dish more vibrant and aromatic.

Recipe Tips
- If potatoes are sticking while drying, use a kitchen towel specifically for drying to absorb moisture effectively without leaving lint. This helps maximize crispiness.
- When the potatoes aren’t smashing well, apply pressure evenly with a flat-bottomed vessel, ensuring it’s stable and can handle the force without tipping.
- If the potatoes aren’t browning, carefully rotate the baking pan halfway through roasting, around 15 minutes, to promote even cooking and get that desired crispiness.
- For underseasoned potatoes, taste them right after smashing and sprinkle with additional fine sea salt. Doing this while hot helps the seasoning adhere better.
- If you find your potatoes softening too much while boiling, check after 15 minutes for fork-tenderness to prevent them from becoming mushy.
Serving Suggestions
Serve crispy smashed fingerling potatoes alongside grilled chicken or baked salmon for a well-rounded meal. A mixed green salad or roasted asparagus enhances the plate’s appeal.
Use to make potato hash or a savory breakfast bowl with eggs and greens. Add to a rustic vegetable salad or serve them with a spicy dipping sauce.
Top with garlic parmesan aioli or a zesty herb yogurt sauce for added flavor. A sprinkle of fresh herbs like parsley or chives also complements the dish nicely.
Recipe variations
- You can use fingerling potatoes for their creamy texture; substitute with small Yukon golds for a similar effect in this crispy smashed potato recipe.
- Add 3/4 teaspoon salt, 3/4 teaspoon black pepper, and 2 teaspoons finely minced fresh thyme to the potatoes before roasting for a balanced seasoning.
- Either extra virgin olive oil or avocado oil can be used to coat the potatoes with about 3 tablespoons, aiding in achieving a golden, crispy crust.
- If you are preparing for a larger group, double the 24-ounce potato amount and roast in batches on a parchment-lined sheet to maintain even crispiness, similar to my Southwest Sweet Potato Black Bean and Rice recipe approach.
