These crash hot potatoes turn simple small potatoes into a crispy, golden side dish that is perfect for any meal. The tender potatoes develop a crunchy exterior with a flavorful smash and a sprinkle of herbs and parmesan that makes them irresistible.

I first made this on a lazy weekend and was amazed at how easily it transformed plain potatoes into something so special. Now it’s a go-to side for whenever I want comfort without fuss.

Ingredients

  • New potatoes or other small round potatoes: which hold their shape and get nice and tender when boiled
  • Olive oil: for crisping the outsides and adding richness to the potatoes
  • Kosher salt: to season and bring out the natural flavor of the potatoes
  • Fresh ground black pepper: for a gentle hint of heat
  • Rosemary or other herbs like thyme or chives: to add an aromatic touch fresh is best for brightness
  • Finely grated Parmesan cheese: that melts with a salty, nutty flavor enhancing every bite

Choose potatoes that are firm and blemish-free for the best texture and even cooking.

Step-by-Step Instructions

Preheat the Oven:
Set your oven to 450 degrees Fahrenheit to get it nice and hot for baking the potatoes crisp.
Boil the Potatoes:
Fill a pot with water and add enough kosher salt to make it taste like the sea. Bring it to a boil, then add the potatoes and cook them until you can easily pierce them with a fork. This step ensures the potatoes are soft inside.
Prepare the Sheet Pan and Arrange Potatoes:
Drizzle olive oil on a sheet pan to prevent sticking and spread the potatoes evenly, leaving plenty of space around each one so the heat can circulate.
Smash the Potatoes:
Using a potato masher, gently press down on each potato until it flattens slightly. Then, rotate the masher ninety degrees and press again to get a rough flattened shape with some edges sticking out. This creates lots of crispy bits when baked. Drizzle more olive oil on top to help with browning.
Season and Add Cheese:
Sprinkle kosher salt, freshly ground black pepper, and chopped rosemary (or your herb of choice) onto the potatoes. Finish with a generous dusting of finely grated Parmesan cheese to add a delicious savory crust.
Bake Until Golden:
Place the sheet pan in your preheated oven and bake for 20 to 25 minutes. The potatoes should be golden brown and sizzling when they are done.

My favorite part is the herb and cheese topping that melts perfectly on the hot potatoes. It reminds me of family dinners where everyone fought for the last crispy potato.

Storage Tips

Keep leftover crash potatoes in an airtight container in the fridge for up to three days. Reheat them in a hot oven or toaster oven to bring back the crispiness instead of the microwave.

Ingredient Substitutions

If you don’t have new potatoes try baby Yukon Gold or red potatoes both roast beautifully and hold their shape well. You can swap rosemary with thyme, chives, or even a pinch of smoked paprika for a flavor twist.

Serving Suggestions

These potatoes pair amazingly with grilled meats, roasted chicken, or as a hearty side for a simple salad. Try topping with sour cream and chives for a loaded potato vibe.

Frequently Asked Questions

What is the purpose of crushing the potatoes?

Gently crushing increases the surface area, allowing more edges to crisp up during baking while keeping the inside tender.

Can I use different herbs besides rosemary?

Absolutely! Thyme, chives, or sage all complement the potatoes well and can be used based on preference.

How do I know when the potatoes are fork-tender?

When a fork easily pierces through the potatoes without resistance, they are tender and ready for the next step.

Is parmesan necessary for this dish?

Parmesan adds a savory, slightly nutty crunch but can be omitted or substituted with other hard cheeses if preferred.

Can I prepare these potatoes ahead of time?

Yes, boil and crush them in advance, then refrigerate. Reheat in the oven for best crispness before serving.
