  • ½ pound baby red potatoes 10-12 similar sized potatoes
  • 3 cloves garlic minced
  • 2 teaspoons garlic powder
  • 4 Tablespoons white to yellow miso paste
  • 2 teaspoons lemon juice
  • 1 Tablespoon fresh thyme chopped
  • 1 teaspoon fresh ground black pepper


Potato Preparation

  • Choose 10-12 similar sized red potatoes and place them in a pot, cover with water, and add 1 teaspoon of salt.
  • Bring to a boil, and parboil red potatoes for 15 minutes.
  • Remove from heat, place the potatoes in a colander in the sink, and rinse with cold water until the potatoes are cool enough to handle.
  • Place potatoes on a baking sheet lined with a silicone baking mat or parchment paper.
  • Using a small ball jar or a sturdy cup with a hard round bottom, smash each potato
  • Combine minced garlic, miso, lemon juice, garlic powder, and ground pepper in a small microwave-safe bowl.
  • Microwave for 30 seconds until ingredients are melted.
  • Using a basting brush, coat the smashed red potatoes with the miso mixture.
  • Now. sprinkle with fresh chopped thyme.


  • The smashed red potatoes can be baked immediately or covered and placed in the refrigerator until ready to bake.
  • Preheat oven to 425 degrees
  • Place smashed red potatoes in the oven, uncovered for 20 minutes.
  • Remove from oven and serve.

Air Frying

  • The smashed red potatoes can be baked immediately or covered and placed in the refrigerator until ready to bake.
  • Preheat the air fryer to 400 degrees.
  • Place in the air fryer in a single layer and cook for 10 minutes until crispy.



  • To make crispy roast potatoes, the oven temperature needs to be hot 220°C or 425°F - but if the oven is too hot, the potatoes will burn before they crisp up. If the oven temperature is too cold, your potatoes will not be crispy. The same applies to the air fryer. Preheat it before cooking the smashed potatoes.
  • Choose potatoes that are approximately the same size. Smaller potatoes take less time to cook, whereas larger potatoes take longer.
  • Store any leftover smashed potatoes in airtight containers in the fridge for up to 3-5 days. To reheat the potatoes right back in the oven at 400 degrees F for about 10 minutes. You can also reheat them in the microwave until warmed through, though they won't be as crispy. If using the air fryer, cook at 350 F for 5 minutes.
  • Other great sauces for this red smashed potato recipe are mustard sauce, lemon basil sauce, yum yum sauce, or ketchup.
  • I love these potatoes as a snack, side dish, or main meal if you're a potato lover.
