If you are looking for a side dish that gives you the best of both worlds—fluffy baked potatoes on the inside and ultra-crispy, golden edges on the outside—these garlic herb smashed potatoes are for you. By boiling the potatoes until tender first and then gently flattening them before a high-heat bake, you create maximum surface area for the butter and Parmesan to crisp up. It is a wonderfully tactile cooking process that yields impressive results with very little fuss.
Why You'll Love This Recipe
- Creates incredible textural contrast with crispy, golden edges and a tender, fluffy center.
- Browning in butter and garlic infuses rich flavor into every single bite.
- Finishing with grated Parmesan cheese adds a savory, umami crust as it melts.
- Uses simple whole ingredients that you likely already have in your kitchen.
Ingredients You'll Need (and Why)
small baby yellow or Yukon Gold potatoes: Their naturally creamy texture and thin skins make them ideal for smashing and crisping up without needing to peel them.
unsalted butter: Carries the garlic and herb flavors evenly across the potatoes while helping the edges turn a deep golden brown in the hot oven.
garlic: Mincing it finely ensures it infuses the melted butter, though keeping an eye on the bake time prevents it from burning and turning bitter.
grated Parmesan cheese: Added right as the potatoes come out of the oven so it melts into the hot crevices and creates a nutty, savory crust.
How to Make It
Boiling for Maximum Tenderness
The secret to a great smashed potato starts on the stovetop. Boiling the potatoes whole in salted water ensures they cook evenly all the way to the center. You want them completely fork-tender so they yield easily when you press down on them later, without breaking apart entirely.
The Gentle Smash and Seasoning
Once dry and arranged on your parchment-lined sheet, use a heavy flat-bottomed glass to press down firmly but carefully. You want to flatten them enough to create rough, jagged edges that will catch the heat of the oven, keeping the potato in one cohesive piece. Spooning the garlic herb butter over the top allows the fats to soak right into those nooks and crannies.
High-Heat Roasting and the Parmesan Finish
A hot oven (425°F) is non-negotiable here; it is what transforms the edges from soft to shatteringly crisp. Sprinkling the Parmesan cheese immediately after they exit the oven lets the residual heat melt the cheese perfectly without scorching it during the bake.
Success Tips
- Boil the potatoes just until fork-tender; if they are overcooked and waterlogged, they will turn to mush when you try to smash them.
- Use parchment paper on your baking sheet to prevent the potatoes from sticking and to help them develop a clean, crispy crust.
- Don't skip the high oven temperature (425°F)—it is essential for getting those deeply golden, crunchy edges.
- Add the Parmesan cheese immediately while the potatoes are piping hot so it melts properly into the crevices.
Variations
- Swap the dried oregano or thyme for Italian seasoning or smoked paprika for a slightly different flavor profile.
- Use extra virgin olive oil instead of butter if you prefer a dairy-free roasting fat.
Storage & Make-Ahead
Fridge: Store leftover smashed potatoes in an airtight container in the refrigerator for up to 3 days. Reheat in a 400°F oven or air fryer to bring back their crispiness.
FAQ
Can I make these ahead of time?
You can boil and smash the potatoes a few hours in advance, keeping them on the baking sheet at room temperature. Just wait to apply the butter and bake them until you are ready to serve.
What kind of potatoes work best?
Small baby yellow potatoes or Yukon Golds are best because of their naturally buttery flavor and thin skins, which crisp up wonderfully in the oven.
Why did my potatoes fall apart when I smashed them?
They may have been slightly overcooked and waterlogged, or pressed down too hard. Next time, cook them just until a fork slides in easily, and press down firmly but gently.
