Why You’ll Love this Smashed Potatoes Recipe

  • CRISPY POTATOES. Drying the boiled potatoes well, oiling and salting the outsides promotes crispier skin with extra flavor.
  • BUTTERY SEASONED BLISS. Melted butter is combined with seasonings then poured over the smashed potatoes to drink up flavor while they roast.
  • NO BLACK BITS. This recipe smartly uses dried herbs and seasonings because fresh can burn at the high roasting temperature and become bitter.
  • PARMESAN. The salty, nutty Parmesan is the crowning glory on our crispy buttery – now cheesy, morsels. 
  • PANTRY FRIENDLY. These garlic Smashed Potatoes are super easy to make with just a few pantry ingredients so you can whip up a showstopper at a moment’s notice.
  • VERSATILE. Once you get the technique, you can adapt the flavor profile to ANYTHING!  Swap the Parmesan for cheddar, add bacon, chorizo, etc. Lots of variations included!
  • PREP AHEAD FRIENDLY. Make the recipe up to smashing, then just add the butter and pop in the oven when ready!

How to Season Smashed Potatoes

Potatoes and salt are one of the most beautiful combinations on the planet.  Add in some butter and herbs and you might have THE most beautiful flavor combination on the planet.

To season the potatoes, we want plenty of salt along with a generous amount of dried garlic and herbs.  I don’t suggest fresh garlic or fresh herbs as they can burn at high temperatures and leave you with unsightly bitter, black bits.

Instead, we infuse our melted butter with salt, garlic powder, dried parsley, dried oregano, dried basil, dried thyme and pepper.  The garlic herb butter seeps into the fleshy potatoes and drizzles down the skin to create buttery bliss.

But it gets better…

Once the garlic smashed potatoes are golden, we add about ¼ cup freshly, finely grated Parmesan Cheese. The salty, nutty Parmesan is the crowning glory on our crispy buttery – now cheesy, morsels.

For the Parmesan, make sure you use FRESHLY, finely grated Parmesan, otherwise the chees won’t melt successfully or taste as irresistible. I find ¼ cup Parmesan to be the ideal amount, but feel free to use as little as 2 tablespoons or as much as ¾ cup – it is totally up to you how cheesy you like your Smashed Potatoes. 

Seasoning Before Roasting Smash Potatoes

  • Salt: Potatoes and salt are one of the most beautiful combinations on the planet! This recipe calls for regular table salt.
  • Butter: Use unsalted butter or the potatoes will be too salty, or reduce the salt in the recipe. The garlic herb butter seeps into the fleshy potatoes and drizzles down the skin to create buttery bliss.
  • Garlic: Use garlic powder for this recipe. I don’t suggest fresh garlic because it can burn and become bitter.
  • Herbs: Again, dried herbs are best otherwise the high roasting temperature will leave you with unsightly bitter, black bits. Instead, the melted butter is infused with dried parsley, dried oregano, dried basil, dried thyme and pepper.
  • Parmesan: Once the garlic smashed potatoes are golden, we add about ¼ cup freshly, finely grated Parmesan Cheese. Take care to use FRESHLY, finely grated Parmesan, otherwise the cheese won’t melt successfully or taste as irresistible

Toppings After Baking Smash Potatoes

Garnish the smashed potatoes simply with fresh green onions or chives, or get elaborate with any toppings you would add to baked potatoes or make it a meal by adding meat! Here are some ideas:

HOW TO MAKE SMASHED POTATOES

You are going to LOVE how easy Smashed Potatoes are to make!  Essentially, you:

  1. Boil
  2. Smash
  3. Butter
  4. Roast! 

It really is that easy, but here is a breakdown of all the steps so you will be a crispy Smashed Potatoes master (full recipe in the printable recipe card at the bottom of the post):

STEP 1:  WASH POTATOES

Even though we are going to be boiling the potatoes, we don’t want them boiling in dirty water! 

STEP 2:  BOIL POTATOES

Next, you want to add your potatoes to a large pot and fill with cold water.  We don’t want to add the potatoes to boiling water because they will not cook evenly – you’ll likely end up with overcooked mushy outsides and under cooked insides.  By bringing the water to a boil with the potatoes, we get evenly cooked potatoes every time. 

Cook your potatoes until fork tender – you might want to poke a few potatoes to ensure they are all cooked.  It is okay if the potatoes split while testing for doneness or even while cooking because we are going to smash them anyway.

STEP 3:  DRY POTATOES

Add your potatoes to a colander to drain. Pat dry with paper towels or a clean kitchen towel.  It is imperative that the skins be dry in order to achieve crispy potatoes.  The dryer the potatoes – the crispier the smashed potatoes!

STEP 4:  OIL AND SALT POTATOES

I am the only smashed potato recipe I’ve seen that oils and salts the outside of the smashed potatoes – and it makes a WORLD of difference! Just like you oil and salt the outside of Twice Baked Potatoes, we want to envelop the entire potato in deliciousness – not just the tops. The oil and salt also promote crispy skins that butter alone cannot.

STEP 5:  SMASH POTATOES

You can use whatever is handy to smash the potatoes – a potato masher, fork or back of a glass, etc.  When you smash the potatoes, be gentle – you want to push slowly so the skin splits but the rest of the potato stays intact.

I have found ½” seems to be the right thickness.  Keep in mind, thinner potatoes will be crispier because more of the potato skin is in contact with the hot baking sheet, whereas, thicker potatoes will be fluffier and not as crispy all over – your call!

STEP 6:  BUTTER POTATOES

Drizzle potatoes evenly with herb butter mixture. If your potatoes are raised in the middle, it helps to push in the center with your finger, so the butter pools into the potatoes instead of off of them. 

If you have extra butter after you’ve spooned it over all of the potatoes, wait a few minutes for the potatoes to absorb the butter then coat again.

STEP 7:  BAKE POTATOES

Bake potatoes for 30-40 minutes depending on size.  You want the skin to be deeply golden which means crispier skins. Once the potatoes look done, add Parmesan and continue to bake until melted, about 2 minutes.

STEP 8:   EAT SMASHD POTATOES!

Let the Smashed potatoes cool for 5 minutes or so, garnish with chives and dig in!

To make ahead:  Follow the recipe through flattening the potatoes.  Let the potatoes cool completely, then cover the pan tightly with foil, or better yet, wrap the entire tray in plastic wrap a couple times.  Refrigerate for up to 8 hours.

You can also grate the Parmesan cheese and make the herb butter ahead of time and refrigerate.  The herb butter will harden in the refrigerator, so simply microwave it when ready to use.

Now all that’s left to complete your crispy Smashed Red Potatoes is to drizzle on the butter and bake!

Smash Potatoes Recipe Variations

The Smashed Potatoes are intoxicating as is, OR:

  • add a dollop of sour cream or Greek yogurt, because creamy + crunchy is always a good idea. 
  • And bacon is always a good idea.
  • You can also swap the Parmesan for cheddar, mozzarella or even brie.
  • Get creative with the toppings such as broccoli, sun-dried tomatoes, mushrooms or even chicken or ground beef.
  • Swap out the flavor profile and add some lemon and kick up the oregano.
  • Swap the seasonings for ranch seasoning and use cheddar instead of Parmesan.
  • Use Mexican seasonings, pepper jack or cheddar, tomatoes, avocados and/or dollops of sour cream, guacamole and green onions.
  • Dip in ranch, ketchup or barbecue sauce (although they don’t need it!)
  • And anything else you can dream up!

Cooking tips for roasted smashed potatoes

  • Use waxy potatoes: this Smashed Potatoes recipe will not work with starchy potatoes, like Russet potatoes, because the skin won’t crisp up.  Instead, only use small waxy potatoes such as red potatoes or Yukon gold potatoes.
  • Use freshly grated Parmesan:  it melts much better and tastes far superior! 
  • Select uniform potatoes:  the size is up to you based on the crispy skin to fluffy inside you prefer, but keep it uniform so the potatoes cook evenly.
  • Don’t use fresh garlic:  it is likely to burn leaving you with bitter, black bits.
  • Add potatoes to cold water and then bring to a boil:  this helps the potatoes cook evenly
  • Cook your potatoes until fork tender:  the more tender the potatoes, the easier they will be to smash.
  • Dry the potatoes well after cooking: the dryer the potatoes, the crispier the Smashed Potatoes!
  • Don’t ignore the outside of the potatoes:  oiling and salting the outside of the potatoes promotes crispier skin and adds flavor.
  • Don’t break the potatoes in half:  press gently and slowly to split the top of the potato but not the bottom!
  • Bake the potatoes long enough:  look for deeply golden potato skins which means crispy skins!

How to serve Roasted Smash Potatoes

Roasted Smashed Potatoes can be served as an appetizer, snack or main dish side.  They are the perfect size for finger food, and can easily be scooped up on a napkin and devoured or with two slices of a knife.

How to Make Smashed Roasted FAQs

ARE SMASHED POTATOES GLUTEN FREE?

Yes!  If you need a gluten free side for your family or entertaining, then this easy Smashed Potato Recipe is for you!  Or if you just want to impress EVERYONE!

Why are smashed potatoes falling apart?

Smashed potatoes may fall apart for the following reasons:
You use the wrong potato such as Russets. Take care to use only baby red or baby Yukon gold potatoes which don’t fall apart as easily.
The potatoes are initially overboiled. They should be fork tender but not falling apart.
The potatoes aren’t dried before roasting. If the potato skins are wet, the won’t crisp up and the potatoes are more likely to fall apart.
The potatoes are smashed too thin. Keep to about ½-inch” thickness, otherwise the potatoes are too fragile.
The potatoes are roasted long enough. The smashed potatoes should be roasted until the bottoms are golden and crisp, which creates a firmer, more stable potato.

Why can’t I get my roast potatoes crispy?

Roast potatoes may not get crispy if they are not properly dried before roasting, if the oven temperature is too low, or if there’s not enough fat/oil for roasting. To achieve crispy roast potatoes, ensure the potatoes are thoroughly dried after boiling, use a sufficiently high oven temperature, and coat them generously in oil before roasting.

Is 425 too hot for potatoes?

No 425°F is not too hot for potatoes, but rather the perfect temperature to ensure a crispy exterior and a tender interior. At this temperature, the high heat helps create a golden and crisp outer layer while allowing the potatoes to cook through in a reasonable amount of time. It also encourages the Maillard reaction, a chemical reaction between amino acids and reducing sugars that contributes to the browning and development of rich flavors.

Ingredients

  • 1.5 lbs. baby red or baby Yukon gold potatoes
  • 1 tablespoon olive oil
  • 4 tablespoons unsalted butter
  • 1/2 teaspoon salt divided
  • 1/2 tsp garlic powder
  • 1/4 tsp EACH dried parsley, dried oregano, dried basil, dried thyme, pepper
  • 1/4 cup freshly finely grated Parmesan cheese

Garnish

  • 2-3 tablespoons chopped chives
  • sour cream optional

Instructions

  • Boil potatoes: Add potatoes to a large pot and fill with water to about 2-inches above potatoes. Cover and bring to a boil, then reduce heat to medium, and continue to cook (covered) for 25 minutes or until potatoes are fork tender.
  • Prep: Meanwhile, preheat oven to 425 degrees F. Line a large baking sheet (half sheet) with foil and lightly spray with cooking spray.
  • Dry and oil potatoes: Drain and rinse potatoes in cool water. Pat dry (for crispy skins) and add potatoes to a large microwave-safe bowl. Drizzle potatoes with 1 tablespoons olive oil and ¼ teaspoon salt. Stir to evenly coat.
  • Smash potatoes. Transfer potatoes to baking sheet, evenly spaced apart. Using a potato masher, fork or back of a glass, gently smash the potatoes to about 1/2-inch thickness. *MAKE AHEAD: If making ahead, stop at this point, let potatoes cool completely and wrap tightly in plastic wrap; refrigerate.
  • Add butter: To the same bowl you tossed the potatoes in oil (don’t wipe out) add butter and melt in the microwave. Stir in ¼ teaspoon salt and all remaining seasonings. Drizzle potatoes evenly with butter mixture. If you have extra, wait a few minutes for the potatoes to absorb the butter then coat again.
  • Roast: Bake potatoes at 425 degrees F for 30-40 minutes (depending on size) or until deeply golden. Add Parmesan and continue to bake until melted, about 2 minutes. Garnish with chives and serve immediately.

Notes

POTATO SIZE

I stick with potatoes about the size of a golf ball.  You can use smaller or larger potatoes and adjust the cooking time accordingly – and your expectations.  Small potatoes will emerge crispier all over because there is a greater ratio of crispy skin to fluffy inside.  Larger potatoes will still get crispy, but have a larger ratio of fluffy inside to crispy skin.  Both are delicious – just different!

Make Ahead

  1. Follow the recipe through flattening the potatoes.
  2. Let the potatoes cool completely, then cover the pan tightly with foil, or better yet, wrap the entire tray in plastic wrap a couple times.
  3. Refrigerate for up to 8 hours.
  4. You can also grate the Parmesan cheese and make the herb butter ahead of time and refrigerate. The herb butter will harden in the refrigerator, so simply microwave it when ready to use.
  5. Now all that’s left to complete your crispy Smashed Red Potatoes is to drizzle on the butter and bake!

    We call these Crack’d Potatoes, as they are that addicting. I don’t know if this helps with getting these more crispy, but I line the sheet pan with foil and spray with cooking spray. More for easier clean up than anything. Thanks for the great recipe.

    • Jen says

      Definitely an appropriate name! Great tip with the foil – everyone loved easy cleanup!
