Small Potato Questions
What counts as a small potato?
Think baby potatoes, new potatoes, or any potato around 1 to 2 inches wide. Fingerlings work too, just smash gently so they do not fall apart.
Do I have to boil them first?
For smashed potatoes, yes, it is the easiest way to guarantee a fluffy center. Roasting from raw works for wedges and cubes, but smashed potatoes need that tender interior before you flatten them.
How do I know they are done boiling?
Time is a guideline. They are ready when a knife slides in with very little resistance and the potato wants to break apart if you push it.
How do I keep them from sticking to the pan?
Use parchment paper or a well-oiled sheet pan. Also, let them roast undisturbed for the first 15 minutes after smashing so a crust can form.
My masher or glass keeps sticking. Help?
Totally normal. If they are grabbing, lightly oil the bottom of your glass or masher, or let the potatoes steam-dry for another minute so the surface is less tacky.
Why are my potatoes not getting crispy?
The usual culprits are too much water or not enough heat. Drain well, let the steam escape for a couple minutes, use enough oil, and roast at 450°F. Also make sure your pan is not crowded. If needed, use two sheet pans so the edges can actually crisp instead of steaming.
Can I make them ahead?
Yes. Boil and smash up to 1 day ahead. Refrigerate on a parchment-lined tray covered so they do not dry out or pick up fridge smells, then roast right before serving. Add the garlic butter at the end.
What should I serve with smashed small potatoes?
Anything that loves a crispy side: roast chicken, burgers, salmon, steak, or a big salad with a sharp vinaigrette. They are also a sneakily great brunch side with eggs.
