Crispy on the outside and tender inside, they bring a rich, savory flavor with fresh herbs and a touch of heat. Whether it’s a weeknight dinner or a special gathering, these potatoes always hit the spot.

Ingredients

  • Mixed baby potatoes: These small potatoes cook evenly and their skin crisps up nicely Make sure to choose firm potatoes without bruises
  • Salted butter: Adds richness and helps create that golden crust Use good quality butter for the best taste
  • Extra virgin olive oil: Boosts flavor and helps with roasting Finish with a drizzle for that perfect texture
  • Whole garlic cloves: Roasting garlic mellows its sharpness and adds sweet depth Choose fresh, firm garlic
  • Oregano parsley and basil: Fresh herbs bring brightness and an herbal lift Pick firm, fragrant leaves for the best aroma
  • Cayenne pepper: Adds a subtle kick to balance the richness Adjust the amount to suit your spice preference
  • Kosher salt and black pepper: Essential for seasoning and bringing all the flavors together Use freshly ground pepper for more impact

Step-by-Step Instructions

Simmer the potatoes:
Start by placing the potatoes in a large pot and covering them with water by about an inch. Add a generous pinch of kosher salt. Bring to a boil then reduce the heat to a simmer. Let them cook for 15 minutes until a fork slides through easily. Drain the potatoes and transfer them to a rimmed baking sheet. Let them cool slightly so they are easier to handle
Next prepare the roasted garlic butter while the potatoes cool:
Combine the butter, peeled garlic cloves, and olive oil in a small baking dish or ovenproof pan. Place it in the preheated oven at 425 degrees Fahrenheit. Roast for 20 to 30 minutes, checking carefully so the garlic becomes a golden caramelized color but does not burn. This step intensifies the garlic flavor and browns the butter Use a fork to mash the roasted garlic into the browned butter. Stir in the chopped oregano, parsley, and basil. Add cayenne pepper to taste along with salt and freshly ground black pepper. This herbaceous mixture is the sauce that will bring the potatoes to life
Smash and prepare the potatoes:
Use the bottom of a flat cup or similar sturdy utensil to gently press down on each potato until it splits open and flattens slightly but remains whole. Drizzle the smashed potatoes with olive oil to help them crisp up in the oven Place the sheet back in the oven and bake the potatoes for 20 minutes Then take the potatoes out and spoon a generous amount of the roasted garlic butter mixture over each one. Return the potatoes to the oven and cook for an additional 10 to 15 minutes until the edges are crisp and deeply golden
Serve:
Serve the smashed potatoes warm and garnish with a sprinkle of extra fresh herbs and a pinch of flaky sea salt for a beautiful finish

Storage Tips

Allow leftovers to cool completely before storing in an airtight container. Keep in the refrigerator for up to three days. To reheat, spread the potatoes on a baking sheet and warm them in a 375-degree oven until heated through and crispy again This method is better than microwaving to maintain the texture

Ingredient Substitutions

If you can’t find mixed baby potatoes, small Yukon Gold or red potatoes work well. For a dairy-free version, swap butter with vegan butter or more olive oil. If fresh herbs aren’t available, you can use dried oregano parsley and basil but use sparingly as dried herbs are more concentrated

Serving Suggestions

These smashed potatoes pair beautifully with grilled meats roasted chicken or a fresh green salad They also make a delicious appetizer served with a sprinkle of Parmesan or a dollop of sour cream For holiday meals or casual dinners they add that special touch without extra effort

Cultural Context
