If you love potatoes with crispy golden edges, buttery garlic flavor, and a cheesy Parmesan crust, these Crispy Garlic-Butter Smashed Potatoes are going to become a regular at your dinner table.
The secret is simple: baby potatoes are boiled until tender, gently smashed, coated in a flavorful garlic-butter mixture, showered with Parmesan, and roasted at high heat until the edges become irresistibly crisp and golden.
The centers stay soft and fluffy while the smashed edges turn wonderfully crunchy. A little fresh chive or green onion at the end adds a fresh bite that balances the rich butter and Parmesan.
They make an easy side dish for chicken, steak, pork, seafood, or roasted vegetables, but honestly, they’re delicious enough to eat straight from the baking dish.
Why You’ll Love These Crispy Smashed Potatoes

- Easy ingredients: You probably already have most of them in your kitchen.
- Perfect side dish: They pair with almost any main course.
- Great for entertaining: They look impressive without requiring complicated preparation.
- Customizable: Add chili flakes, breadcrumbs, extra Parmesan, or your favorite herbs.
Ingredients You’ll Need
Baby Potatoes
Use small baby potatoes, preferably potatoes that are similar in size so they cook evenly. Yellow, red, or small Yukon Gold potatoes all work well.
You’ll need about 1½–2 pounds (700–900 g).
Butter
Melted butter gives the potatoes their rich, irresistible flavor and helps the Parmesan topping brown beautifully.
Olive Oil
A little olive oil helps with roasting and contributes to crispy edges without making the potatoes feel overly heavy.
Fresh Garlic
For the best garlic flavor, finely mince fresh garlic cloves rather than relying entirely on garlic powder.
Parmesan
Freshly grated Parmesan gives the potatoes a savory, salty crust. For the crispiest finish, grate it fairly finely.
Paprika
Paprika adds subtle warmth and beautiful color to the potatoes.
Italian Herbs or Oregano
Dried Italian seasoning or oregano works perfectly here. You can also experiment with rosemary or thyme.
Chives or Green Onions
Freshly chopped chives or green onions provide a bright finishing touch.
Optional Breadcrumbs
A couple of tablespoons of breadcrumbs can make the crust even crunchier.
Optional Chili Flakes
If you like a little heat, add a pinch of red pepper flakes to the garlic-butter mixture.

Keyword: crispy smashed potatoes
Ingredients
- 1½–2 lb (700–900 g) baby potatoes
- 4 tablespoons butter, melted
- 3 tablespoons olive oil
- 4–5 cloves garlic, finely minced
- ½ cup grated Parmesan
- 1 teaspoon paprika
- ½ teaspoon garlic powder
- ½ teaspoon dried Italian herbs or oregano
- ¾ teaspoon salt, plus more for boiling
- ½ teaspoon black pepper
- 2–3 tablespoons chopped fresh chives or green onions
- 2 tablespoons breadcrumbs, optional
- Pinch of chili flakes, optional
How to Make Crispy Garlic-Butter Smashed Potatoes
1. Boil the Potatoes
Place the baby potatoes in a large pot and cover them with cold water.
Add a generous amount of salt to the water. Bring it to a boil and cook the potatoes for about 15–20 minutes, or until they are fork-tender.
You want the potatoes soft enough to smash easily but still firm enough to hold their shape.
Drain them well and let them sit for about 5 minutes so excess moisture can evaporate.
Don’t skip the steam-drying step. Drier potatoes generally roast more effectively and develop better crispy edges.
2. Make the Garlic-Butter Mixture
While the potatoes are cooking, combine the melted butter and olive oil in a small bowl.
Add:
- minced garlic
- paprika
- garlic powder
- dried Italian herbs or oregano
- salt
- black pepper
- chili flakes, if using
Stir everything together until well combined.
The combination of melted butter, olive oil, garlic, and seasonings creates the flavorful coating that makes these potatoes so good.
3. Smash the Potatoes
Preheat your oven to 425°F (220°C).
Lightly grease a baking sheet or baking dish.
Arrange the boiled potatoes in a single layer, leaving a little space between them whenever possible.
Using the bottom of a drinking glass, a potato masher, or the flat side of a measuring cup, gently press each potato down.
Don’t completely flatten them.
The goal is to create potatoes that are flattened with plenty of rough, craggy edges while keeping the center intact.
Those rough edges are exactly where the crispy magic happens.
4. Add the Garlic Butter
Generously brush or spoon the garlic-butter mixture over each smashed potato.
Make sure the butter and garlic mixture gets into the cracks and crevices.
Sprinkle the grated Parmesan evenly over the tops.
If you’re using breadcrumbs, scatter them over the potatoes now.
5. Roast Until Golden and Crispy
Place the potatoes in the preheated oven and roast for approximately 25–30 minutes.
They’re ready when the edges are deeply golden and crisp and the Parmesan has browned.
For the beautifully browned tops shown in the photo, switch the oven to broil/grill for 2–4 minutes at the end.
Keep a close eye on them during broiling because the Parmesan can go from beautifully golden to burnt very quickly.
6. Add the Finishing Touches
Remove the potatoes from the oven and, if desired, drizzle them with a small amount of melted butter.
Scatter freshly chopped chives or green onions over the top.
Serve immediately while the potatoes are hot and crispy.
Tips for Making the Crispiest Smashed Potatoes
Don’t Overboil the Potatoes
The potatoes should be tender enough to smash but not falling apart.
If they’re overcooked, they can become difficult to transfer and may turn mushy rather than developing distinct crispy edges.
Let Them Steam-Dry
After draining, allow the potatoes to sit for several minutes.
Excess moisture is one of the enemies of crispy roasted potatoes.
Don’t Smash Them Too Thin
You want a combination of crispy outside and fluffy inside.
If you flatten the potatoes too aggressively, they may become crisp throughout instead of retaining that soft potato center.
Use Plenty of Surface Area
Spread the potatoes out rather than crowding them together.
If the potatoes are touching too much, they can steam instead of roast.
Use two baking sheets if necessary.
Don’t Be Shy With the Seasoning
Potatoes can absorb quite a bit of seasoning, especially after boiling.
Salt the cooking water generously and season the garlic-butter mixture properly.
Parmesan Matters
For the best texture, freshly grated Parmesan is ideal.
It melts into the potato surface and develops delicious browned, savory bits as it roasts.
Broil at the End
If you want that deeply golden restaurant-style appearance, a short blast under the broiler can make a big difference.
Just stay nearby and watch carefully.
Should You Peel the Potatoes?
No.
One of the best things about this recipe is that baby potatoes don’t need to be peeled.
The skins become wonderfully crisp during roasting and add texture and flavor.
Simply wash and scrub the potatoes well before boiling.
What Are the Best Potatoes for Smashed Potatoes?
Small potatoes with a creamy interior work particularly well.
Good options include:
- Baby Yukon Gold potatoes
- Small red potatoes
- Baby yellow potatoes
- Mixed baby potatoes
The most important thing is to choose potatoes that are relatively similar in size so they finish cooking at roughly the same time.
Can I Make These Smashed Potatoes Ahead of Time?
Yes.
You can boil the potatoes ahead of time and allow them to cool completely.
Store them covered in the refrigerator until you’re ready to prepare the dish.
When ready to cook, smash the potatoes, season them, and roast them at high heat.
For the best texture, I recommend roasting them shortly before serving rather than fully cooking them hours ahead.
Can I Make Smashed Potatoes in an Air Fryer?
Yes.
An air fryer is an excellent way to make crispy smashed potatoes.
Prepare and smash the potatoes as directed, coat them with the garlic-butter mixture and Parmesan, then arrange them in the air fryer basket in a single layer.
Air-fry at approximately 400°F (200°C) until deeply golden and crisp, checking them periodically because cooking times vary between air fryers.
You may need to work in batches to prevent overcrowding.
Can I Add Other Toppings?
Absolutely.
This recipe is easy to customize.
Try adding:
- Extra Parmesan
- Shredded mozzarella
- Cheddar cheese
- Crispy bacon
- Fresh parsley
- Fresh rosemary
- Fresh thyme
- Green onions
- Chives
- Red pepper flakes
- Smoked paprika
- A drizzle of ranch dressing
- Sour cream
- A little lemon zest
For a spicy version, add extra chili flakes or a pinch of cayenne pepper to the garlic-butter mixture.
What to Serve With Crispy Smashed Potatoes
These potatoes are incredibly versatile.
Serve them alongside:
Chicken
They pair beautifully with roasted chicken, grilled chicken, baked chicken thighs, or garlic chicken.
Steak
The crispy Parmesan potatoes make a fantastic side dish for steak, especially with a simple salad or roasted vegetables.
Pork
Try them with pork chops, pork tenderloin, or roasted pork.
Seafood
They’re also delicious alongside salmon, shrimp, cod, or other baked seafood dishes.
Holiday Dinners
Because they’re easy to prepare in a large batch, they’re a great addition to Thanksgiving, Christmas, Easter, or other family gatherings.
How to Store Leftover Smashed Potatoes
Allow leftover potatoes to cool before transferring them to an airtight container.
Refrigerate for up to 3–4 days.
For the best texture, reheat them in an oven, toaster oven, or air fryer rather than the microwave.
Reheating at a higher temperature helps bring back some of their crispiness.
How to Reheat Smashed Potatoes
Oven
Place the potatoes on a baking sheet and reheat at 400°F (200°C) until hot and crisp.
Air Fryer
Air-fry at around 375–400°F (190–200°C) until heated through and crispy again.
Microwave
The microwave is the quickest option, but the potatoes will generally be softer rather than crispy.
Frequently Asked Questions
Why aren’t my smashed potatoes crispy?
The most common reasons are excess moisture, overcrowding, insufficient oil, or an oven temperature that isn’t high enough.
Make sure the boiled potatoes steam-dry before smashing, leave space between them, and roast them at high heat.
How do you get smashed potatoes really crispy?
Boil the potatoes until tender, allow them to steam-dry, smash them relatively thin without completely flattening them, coat them generously with oil and butter, and roast them at 425°F (220°C).
A short broil at the end can create an especially golden crust.
Do you have to boil potatoes before smashing them?
For this recipe, yes.
Boiling first makes the potatoes tender enough to smash while roasting afterward creates the crispy exterior.
Can I use large potatoes?
You can, but baby potatoes are much easier to prepare because they naturally create individual portions.
If using larger potatoes, cut them into smaller pieces before boiling.
Can I use garlic powder instead of fresh garlic?
Yes, but fresh garlic gives the potatoes a more pronounced garlic flavor.
For the best result, use both fresh minced garlic and garlic powder as written in the recipe.
Can I make these without Parmesan?
Absolutely.
Parmesan adds a delicious savory crust, but you can leave it out or substitute another hard cheese.
The potatoes will still be crispy and flavorful.
Why do my smashed potatoes fall apart?
They may have been boiled too long or smashed too aggressively.
Cook them only until fork-tender and press down gently enough that each potato remains mostly intact.
Recipe Variations
Loaded Smashed Potatoes
Top the finished potatoes with crispy bacon, cheddar cheese, sour cream, and green onions.
Spicy Garlic Smashed Potatoes
Add red pepper flakes and a small pinch of cayenne to the garlic-butter mixture.
Rosemary Parmesan Smashed Potatoes
Replace the Italian herbs with finely chopped fresh rosemary.
Lemon Garlic Smashed Potatoes
Add a little fresh lemon zest after roasting and finish with a squeeze of lemon juice.
Extra-Cheesy Smashed Potatoes
Add additional Parmesan during the final few minutes of roasting and broil briefly until bubbling and golden.
Why This Recipe Works
There are several simple techniques working together in this recipe.
Boiling makes the potato interior soft and creamy.
Smashing increases the surface area, creating more opportunities for crispy edges.
Butter and olive oil help with browning while adding rich flavor.
Parmesan creates a savory, golden crust.
High-temperature roasting removes moisture from the exterior and encourages browning.
Finally, broiling gives the tops an extra burst of intense heat for those deeply browned, crunchy spots.
The result is exactly what you want from a smashed potato: crispy, golden edges with a soft, fluffy center.
