These air fryer garlic parmesan smashed potatoes are the perfect side dish to any of your favourite main dishes. Fluffy baby potatoes are seasoned with a garlicky, herby butter, and crisped to perfection in the air fryer. These potatoes are perfect on their own, or dipped in zesty homemade ranch, or avocado goddess dressing!
What Are Smashed Potatoes?
Smashed potatoes are not to be confused with their cousin, the forever delicious, mashed potato. Like the name suggests, smashed potatoes are potatoes that have been parboiled, and then smashed down. By smashing down the potatoes, you get lots of crevices that hold onto seasoning, and of course, get perfectly crispy!
👩🏽🍳 Why This Recipe Works
The texture is perfect! They are super crunchy on the outside, and light and fluffy on the inside - the best of all worlds! My air fryer hasselback potatoes are another version of air fryer potatoes, with the perfect crisp exterior and soft interior!
Low maintenance! All you need is to boil your potatoes, and pop these potatoes in an air fryer basket. No oven preheating, and no deep frying! If you love low maintenance potato dishes, my Classic Potatoes au Gratin, or jazzed up Southwest Potatoes au Gratin are super easy, too!
No peeling required! For weeknight dinners, peeling vegetables can be a pain. You do not need to peel these potatoes, which can be a major time saver. My roasted hot honey carrots are another great no-peel option!
- Baby potatoes: Baby potatoes are perfect for this recipe for two reasons. First, they are the perfect size to cook quickly, and smash easily. Second, the baby potatoes tend to have a lighter, fluffier texture than larger potatoes. This makes them ideal for smashing.
- Salted butter: I recommend using salted butter for these potatoes, as it adds another layer of flavour. Potatoes can be bland on their own, so salted butter definitely helps!
- Fresh garlic: Garlic is one of the main flavours of these potatoes. Because of that, I recommend using fresh garlic and mincing it at home. Pre-minced, jarred garlic sometimes has a metallic or muted taste to it. With that being said, always use what you are comfortable with or what you enjoy!
- Parmesan cheese: I highly suggest using fresh parmesan cheese, and grating it at home. You can also use pre-grated parmesan cheese that you would find in the deli section of the grocery store. I do not suggest using the infamous canned parmesan cheese for this recipe.
- Spices and seasoning: You will need old bay seasoning, and garlic and onion power.
A full list of ingredients with measurements is located on the recipe card, below.
- Baby potatoes: You can also use fingerling potatoes for these smashed potatoes. You will a different shaped smashed potato, but the texture and flavour will be the same.
- Salted butter: If you prefer to control the salt content and levels in your cooking, feel free to use unsalted butter and season to your taste. Alternatively, you can use olive oil.
- Fresh garlic: You can also substitute by using all garlic powder, or roasted garlic if you have it on hand. If you have roasted garlic butter on hand, even better!
- Truffle: Drizzle with truffle oil to finish, for a fancy twist on these smashed potatoes.
- Greek: Add lemon and oregano to the butter mixture, and finish with crumbled feta cheese instead of parmesan, for a Greek twist!

💭 Expert Tip
For the crispiest potatoes, you may need to air fry the potatoes in two batches to avoid overcrowding, depending on the size of your air fryer. An even layer of potatoes will let the air circulate all around, resulting in super crispy smashed potatoes.
