What are Smashed Potatoes/ How to Make Smashed Potatoes

Step aside mashed potatoes there is a new friend in town…

Have you ever made smashed potatoes? You start by boiling the potatoes then placing them onto a greased baking sheet.

Using the back of a spoon or a small cup- carefully smash the potatoes until flattened but still in one piece. Drizzle them with olive oil and the bake until crispy! That’s it. This recipe takes it to a new level by adding tomatoes and pesto. So fresh and delicious!

The distinct result of smashed potatoes is achieving a soft and buttery texture on the inside from boiling the potatoes and then crisping them in the oven at the end.

The smashing process allows more surface area for the potato to get crispy. Oh yeah! Maximize the crisp factor by creating crevices for the oil to coat and create a nice browned look and delicious taste.

What’s the difference between smashed potatoes and mashed potatoes?

Mashed Potatoes are creamed potatoes with milk and butter – smashed potatoes are boiled until soft and simply pressed or “smashed” with a fork. Then baked until crispy with cheese and desired toppings.

Tips for Roasted Smashed Potatoes and Tomatoes with Pesto

  • Make your own pesto – I’ve made this recipe with both store-bought and homemade pesto. In the recipe card I share my homemade pesto recipe –  you can use store-bought but I would recommend homemade just because of it’s fresh, vibrant flavor.
  • Use baby potatoes – I know potatoes are potatoes, but this recipe only works with small baby potatoes – either red or golden potatoes work.
  • Make sure potatoes are tender – to perfectly smash potatoes, they need to be tender enough to press with the back of a fork, spoon, or glass cup. Test the potatoes with a fork before you drain boiling water to check that they are done.

This is the most delicious roasted smashed potatoes recipe – tender on the inside, crispy & with roasted tomatoes, topped with fresh basil pesto. A healthy & easy side dish for any dinner! 

What to serve with Roasted Smashed Potatoes and Tomatoes with Pesto

Storage and Reheating

If you have any leftovers, store the potatoes and the pesto separately in the refrigerator, both covered in an airtight container.

The pesto will stay good for about a week, but you’ll want to eat the potatoes within 3 or 4 days. Reheat them in the oven at 350°F until they’re hot.

There’s no need to reheat the pesto sauce, because you don’t want the oil to separate. It will heat up on its own when you add it to the potatoes or any other warm dish!

Roasted Smashed Potatoes and Tomatoes with Pestoyes, please! These smashed potatoes, tomatoes and pesto are golden brown and crispy; these spuds will change how you think about small potatoes. They are soft on the inside with crispy edges- an all-around potato-perfect combo!


  • Total Time: 35 minutes
  • Yield: 6 servings 1x


Units Scale
  • 1 Recipe for Fresh Arugula Walnut Pesto or Homemade Basil Pesto
  • 1.5 lb (680 grams) small Yukon gold or honey gold potatoes, washed
  • 1 lb (454 grams) grape tomatoes or tomato medley variety, cut in half
  • 3 tablespoons olive oil, more for topping
  • 1 cup arugula salad
  • 1/4 cup chopped walnuts for topping
  • Salt and Pepper to taste


  1. Preheat oven to 450 degrees F
  2. Bring a large pot of water to a boil. Once the water starts to boil, add 2 Tablespoons of Kosher salt and plunge the potatoes into hot water. If the water boils too much, lower the heat to medium-high. Let cook for about 10 minutes or until fork tender (not falling apart). 
  3. Grease a large baking sheet with olive oil. Drain potatoes and place in rows on a baking sheet. Use the back of a spoon or a small cup to smash each potato. Apply gentle pressure and push down with more force to create the smashed look. 
  4. Add cut tomatoes to a baking sheet spreading evenly, in a single layer, with potatoes. Drizzle potatoes and tomatoes with olive oil. 
  5. Bake for 20 minutes until the edges of the potatoes are crispy—season with salt and pepper. Transfer to a serving dish and top with pesto, a generous drizzle of olive oil, fresh arugula, and chopped walnuts. Serve warm or cold. 


Top tip:

  • Don’t overcrowd your baking pan with the potatoes and tomatoes, or they will steam and not crisp. If making a double batch, cook on two separate baking trays.  


  • Add fresh mozzarella or burrata cheese to the final dish for a cheesy twist.

  1. I had some trouble smashing cleanly, and I ended up over-roasting the tomatoes, but I would totally make this again! I served over fresh arugula and added some garbanzos for a little protein. It made for a very delicious vegan meal!

    1. I love your addition of garbanzo beans! You can also try a meat mallet on a cutting board for easier smashing- if you have one. Happy you enjoyed it.
