Step-by-Step Instructions
1. Prepare the Potatoes
Wash the baby potatoes thoroughly and remove any dirt. You can leave the skins on because they become wonderfully crispy during roasting.
Place the potatoes in a large pot and cover them with cold water. Add a generous pinch of salt.
Bring the water to a boil, then reduce the heat slightly and cook for about 15–20 minutes, or until the potatoes are fork-tender.
Be careful not to overcook them. They should be soft enough to smash but still hold their shape.
2. Preheat the Oven
While the potatoes are cooking, preheat your oven to 425°F (220°C).
For especially crispy potatoes, place a large baking sheet in the oven while it preheats. A hot baking sheet helps the potatoes begin crisping immediately when they hit the surface.
3. Drain and Dry
Drain the potatoes thoroughly and let them sit for a few minutes so excess moisture can evaporate.
This step is important because dry potatoes roast much better than wet potatoes. Less moisture means more crispy, golden edges.
4. Smash the Potatoes
Transfer the potatoes to a large baking sheet lined with parchment paper or lightly greased.
Using the bottom of a glass, measuring cup, potato masher, or sturdy spatula, gently press each potato until it is flattened to about ½-inch thick.
Don’t smash them too aggressively. You want the potato to remain in one piece with plenty of uneven edges that can become crispy.
5. Prepare the Garlic Parmesan Mixture
In a small bowl, combine the olive oil, minced garlic, Parmesan cheese, salt, black pepper, garlic powder, and Italian seasoning if using.
Mix well until the ingredients are evenly combined.
If you prefer an especially crisp finish, you can reserve some of the Parmesan for sprinkling over the potatoes during the final few minutes of roasting.
6. Season the Potatoes
Brush or spoon the garlic Parmesan mixture generously over each smashed potato.
Make sure the oil reaches the edges and the garlic and Parmesan are distributed evenly.
For extra flavor, sprinkle a little additional Parmesan over the top.
7. Roast Until Crispy
Place the baking sheet in the preheated oven and roast for approximately 25–30 minutes.
The potatoes should become golden brown with crispy edges.
For an even darker and crunchier finish, switch the oven to broil for the final 1–2 minutes, watching carefully so the Parmesan and garlic do not burn.
8. Garnish and Serve
Remove the potatoes from the oven and let them cool for 2–3 minutes.
Sprinkle with freshly chopped parsley and additional Parmesan if desired.
For a fresh finishing touch, add a tiny amount of lemon zest or a squeeze of fresh lemon juice before serving.
Best Tips for Extra-Crispy Smashed Potatoes
The type of potato makes a difference. Small yellow, gold, or red potatoes work particularly well because they have creamy interiors and skins that become crisp when roasted.
Don’t skip the drying step after boiling. Excess water creates steam in the oven and can prevent the potatoes from developing crispy edges.
For maximum crispiness, make sure there is space between each potato. If the baking sheet is overcrowded, the potatoes will steam instead of roast.
Press the potatoes fairly thin, but don’t flatten them so much that they fall apart. Around ½ inch thick provides a good balance between a crispy exterior and fluffy center.
Use freshly grated Parmesan whenever possible. It melts and browns more effectively than many pre-shredded varieties.
Best Ingredient Options
Baby Yukon Gold potatoes are an excellent choice because they become creamy inside while developing crisp golden edges.
Baby red potatoes also work beautifully and provide a slightly firmer texture.
Extra-virgin olive oil gives the potatoes a rich, savory flavor, but melted butter can be used for an even richer finish. You can also use a combination of olive oil and melted butter.
Fresh garlic provides the strongest flavor, while garlic powder can be added for an extra layer of garlic seasoning.
Recipe Variations
For a spicy version, add a pinch of red pepper flakes or cayenne pepper to the seasoning mixture.
For a cheesy variation, add a little shredded mozzarella or sharp cheddar during the final few minutes of roasting.
For a herb version, add fresh rosemary, thyme, or chives along with the parsley.
For a lemon-herb version, finish the roasted potatoes with fresh lemon zest, parsley, and a small squeeze of lemon juice.
For an extra-garlicky version, add roasted garlic instead of some of the fresh minced garlic for a sweeter, deeper flavor.
What to Serve With Crispy Garlic Parmesan Smashed Potatoes
These potatoes pair wonderfully with grilled or roasted beef, chicken, turkey, or fish.
They are also an excellent side dish for roast beef, steak, burgers, meatballs, or a hearty casserole.
For a lighter meal, serve them alongside a fresh green salad and roasted vegetables.
Make-Ahead Instructions
You can boil and smash the potatoes several hours ahead of time.
Arrange the smashed potatoes on a baking sheet, cover them, and refrigerate until you’re ready to cook.
When you’re ready to serve, add the garlic Parmesan seasoning and roast them directly from the refrigerator. You may need to add a few extra minutes to the cooking time.
Storage
Allow leftover potatoes to cool completely before transferring them to an airtight container.
Refrigerate for up to 3–4 days.
For the best texture, avoid leaving them uncovered in the refrigerator because they can dry out.
Reheating
The oven or air fryer is the best way to bring back their crispy texture.
For the oven, heat them at 400°F (200°C) for about 8–12 minutes, or until hot and crisp.
In an air fryer, reheat at 375°F (190°C) for approximately 4–7 minutes.
Microwaving is convenient but will make the potatoes softer rather than crispy.
Freezing
These smashed potatoes can be frozen, although their texture may be slightly different after thawing.
Arrange completely cooled potatoes on a baking sheet and freeze them until solid. Transfer them to a freezer-safe container or bag.
They can be stored for up to 2 months.
Reheat them directly from frozen in a 400°F (200°C) oven or air fryer until hot and crispy.
Common Mistakes to Avoid
Overboiling the Potatoes
If the potatoes become too soft, they can fall apart when smashed. Cook them only until they are fork-tender.
Leaving the Potatoes Too Wet
Moisture is one of the biggest enemies of crispy roasted potatoes. Allow them to drain and steam-dry before smashing.
Crowding the Baking Sheet
Give each potato enough space for hot air to circulate around it. Use two baking sheets if necessary.
Using Too Little Oil
A light coating of oil helps the potatoes develop their signature golden crust. Make sure the exposed surfaces and edges are lightly coated.
Burning the Garlic
Garlic can brown quickly at high temperatures. If your garlic pieces are very small, consider mixing them into the oil carefully or adding some during the later part of roasting.

Frequently Asked Questions
Can I use regular potatoes?
Yes. Small or medium Yukon Gold or red potatoes work particularly well. If using larger potatoes, cut them into smaller pieces before boiling.
Why aren’t my smashed potatoes crispy?
The most common reasons are excess moisture, overcrowding, insufficient oil, or an oven that isn’t hot enough. Make sure the potatoes are well drained and dry, leave plenty of space between them, and roast at 425°F (220°C).
Can I make these potatoes without Parmesan?
Absolutely. You can leave out the Parmesan and increase the garlic, herbs, and seasoning. However, Parmesan adds a delicious savory and slightly crispy crust.
Can I use butter instead of olive oil?
Yes. Melted butter works very well and creates a rich flavor. For the best balance, you can also use half olive oil and half melted butter.
Can I make them in an air fryer?
Yes. Arrange the smashed potatoes in a single layer and air fry at approximately 400°F (200°C) for 15–20 minutes, depending on their thickness and your air fryer.
How do I make them even crispier?
Dry the potatoes thoroughly, smash them relatively thin, avoid overcrowding the pan, and roast them on a preheated baking sheet. You can also finish them under the broiler for 1–2 minutes.
