WHY MAKE IT
A little comfort, a lot of flavor.
Crispy smashed potatoes have emerged as a premier modern appetizer, combining the fluffy, pillowy interior of a baked potato with the satisfying crunch of a kettle-cooked chip. In this Middle Eastern-inspired interpretation, baby Yukon Gold potatoes are parboiled until tender, crushed to maximize surface area, and coated in rich extra-virgin olive oil and fragrant za'atar. As the edges roast at high temperature, the sesame seeds toast and the wild thyme perfumes the blistered potato skins. To cut through the savory starch, an accompanying garlic and lemon aioli made with safe, pasteurized egg mayonnaise adds bright citrus acidity, resulting in an irresistible, crowd-pleasing finger food.
The Parboil and Steam-Dry Method
A two-stage cooking method is essential for achieving tender centers alongside brittle, crackling edges. Boiling parcooks the interior starches into a creamy consistency that cannot be achieved through dry roasting alone. However, introducing wet potatoes directly into hot oil causes sogginess and spattering. Allowing the drained potatoes to steam-dry on a wire rack for ten minutes allows trapped water vapor to escape into the air. This essential step dries the outer epidermis completely, priming the skin to absorb hot olive oil and crisp dramatically in the oven.
Maximizing Edges and Za'atar Adhesion
Smashing creates uneven topography across the potato flesh, generating craggy peaks, rough ridges, and thin ruffled borders that fry against the hot metal pan. Applying oil before seasoning ensures the za'atar spice blend adheres directly to the exposed starch. The roasted sesame seeds in authentic za'atar bloom in the oven's high ambient heat, releasing nutty oils, while dried sumac imparts a subtle berry-like tang. Ensure the crushed disks are spaced generously on the sheet to prevent trapped steam from softening neighboring edges.
Creating the Bright Citrus Aioli
The rich, starchy crunch of roasted potatoes requires a sharp, creamy dip to balance the palate. Using halal-certified mayonnaise made with pasteurized eggs ensures both safety and convenience while maintaining a stable emulsion. Whisking fresh lemon juice, grated lemon zest, and finely microplaned raw garlic directly into the cold mayonnaise creates a pungent, glossy condiment. The sharp citric acid cuts cleanly through olive oil richness, while fresh parsley adds an herbaceous lift that mirrors the dried herbs on the potatoes.
Before you start
Allowing the boiled potatoes to steam-dry completely before smashing is critical for superior crispness. If water droplets remain on the skin when crushed, moisture becomes trapped against the baking sheet and steams the potatoes rather than roasting them. When smashing, apply even, downward pressure with a flat-bottomed jar or glass wrapped in parchment paper to prevent sticking, keeping the potato intact as a single textured disk.
THE RECIPE
Crispy Smashed Za'atar Potatoes with Lemon Aioli
4 servings · 20 minutes preparation · 45 minutes cooking · 10 minutes cooling, chilling or resting
Ingredients
Step-by-step instructions
- Place 2 pounds (900 g) of scrubbed baby Yukon Gold potatoes into a 4-quart saucepan, cover with cold tap water by at least 1 inch, and stir in 1 tablespoon of fine sea salt.
- Bring the water to a rolling boil over high heat, then reduce to medium and simmer uncovered for 15 to 20 minutes until a fork pierces the center of the largest potato with ease.
- Drain the potatoes thoroughly into a colander and allow them to steam-dry on a wire rack for 10 minutes to eliminate surface moisture.
- Preheat the oven to 425°F (218°C) and brush a large rimmed baking sheet with 1 tablespoon of extra-virgin olive oil.
- Transfer the dry potatoes to the baking sheet with ample space between them, and use the flat bottom of a sturdy drinking glass to crush each potato gently until flattened to a 1/2-inch thickness without breaking apart completely.
- Drizzle the smashed potatoes with the remaining 3 tablespoons of extra-virgin olive oil, then season evenly with 2 tablespoons of za'atar, 1/2 teaspoon of garlic powder, 1/2 teaspoon of kosher salt, and 1/4 teaspoon of black pepper.
- Roast in the preheated oven for 25 to 30 minutes until the edges are deep golden, blistered, and audibly crisp.
- While potatoes roast, whisk together 1/2 cup (115 g) of halal mayonnaise, 1 grated garlic clove, 1 1/2 tablespoons of lemon juice, 1/2 teaspoon of lemon zest, and 1 tablespoon of minced parsley in a small ceramic bowl.
- Transfer the sizzling potatoes to a serving platter, allow to cool for 2 minutes, and serve immediately alongside the chilled lemon garlic aioli.
Kitchen notes

Storage & make-ahead
Cool leftover potatoes and aioli separately, then transfer to individual airtight containers and refrigerate within 2 hours. Keep refrigerated for up to 3 days. To restore the shatteringly crisp exterior of the potatoes, reheat them on a rimmed baking sheet at 400°F (204°C) for 8 to 10 minutes until hot throughout. Do not heat the mayonnaise-based aioli.

Frequently asked questions
What type of potato works best for smashing?
Baby Yukon Gold or small yellow potatoes are ideal because their thin skins crisp effortlessly and their yellow flesh remains moist and buttery. Avoid russet varieties, which tend to crumble into pieces rather than flattening into a cohesive, crackling disk when pressed.
Can I prepare the potatoes ahead of time?
Yes, boil and drain the potatoes up to 24 hours in advance. Store them whole in an airtight container in the refrigerator. When ready to serve, smash the cold potatoes onto the oiled baking sheet, season with za'atar, and roast, adding 5 extra minutes to achieve maximum crispness.
How can I prevent the za'atar from burning?
The sesame seeds and dried herbs in za'atar can scorch if exposed to dry heat without enough fat. Be generous with the olive oil coating over the smashed potato tops, ensuring the spices are well-saturated before sliding the sheet into the 425°F (218°C) oven.
