Ingredients
- 1½ lbs (680 g) baby potatoes
- 4 tablespoons butter, melted
- ¾ cup finely grated Parmesan cheese
Optional Seasonings
- ½ teaspoon garlic powder
- ½ teaspoon Italian seasoning
- ¼ teaspoon black pepper
- Fresh parsley, for garnish
Instructions
Step 1: Prepare the Potatoes
Preheat your oven to 425°F (220°C).
Wash the baby potatoes thoroughly.
Place them in a large pot and cover with cold, salted water.
Bring to a boil and cook for approximately 15–20 minutes, or until the potatoes are tender when pierced with a fork.
Drain well and allow them to steam-dry for a few minutes.
Step 2: Prepare the Baking Sheet
Line a large baking sheet with parchment paper.
For extra-crispy potatoes, you can lightly grease the parchment with some of the melted butter.
Step 3: Smash the Potatoes
Arrange the cooked potatoes on the baking sheet, leaving space between them.
Using the bottom of a glass, measuring cup, or potato masher, gently press each potato until it’s flattened to approximately ½ inch thick.
Don’t smash them completely flat—the rough edges are what become beautifully crispy in the oven.
Step 4: Add the Butter
Brush the tops of the smashed potatoes generously with melted butter.
Turn them over and brush the other side as well if desired.
Step 5: Add the Parmesan
Sprinkle Parmesan generously over each potato.
For the crispiest Parmesan crust, place some cheese directly underneath each potato before setting it back down.
Sprinkle with garlic powder, Italian seasoning, or black pepper if using.
Step 6: Bake
Bake for approximately 25–30 minutes, or until the potatoes are deeply golden and crisp around the edges.
For an extra-crispy finish, switch the oven to broil for the final 1–2 minutes, watching carefully so the Parmesan doesn’t burn.
Step 7: Serve
Remove the potatoes from the oven and let them cool for a couple of minutes.
Garnish with fresh parsley if desired.
Serve immediately while the edges are crispy and the Parmesan is golden.
Tips for Extra-Crispy Smashed Potatoes
Choose small potatoes
Baby Yukon Gold, red potatoes, or other small waxy potatoes work particularly well.
Don’t skip the drying step
After boiling, let the potatoes steam-dry. Excess moisture can prevent them from becoming properly crisp.
Don’t overcrowd the pan
Leave space between the potatoes so hot air can circulate around them.
Smash them evenly
A thickness of around ½ inch gives you the ideal balance between a crispy exterior and fluffy center.
Use finely grated Parmesan
Finely grated Parmesan melts and browns beautifully, creating a delicious crispy cheese crust.
Delicious Variations
Garlic Parmesan Potatoes
Add garlic powder or a little minced fresh garlic to the melted butter.
Herb Parmesan Potatoes
Add rosemary, thyme, parsley, or Italian seasoning.
Spicy Parmesan Potatoes
Add crushed red pepper flakes or a pinch of cayenne.
Cheesy Smashed Potatoes
Sprinkle a little shredded mozzarella or cheddar over the potatoes during the final few minutes of baking.
Bacon Parmesan Potatoes
Top the finished potatoes with crispy crumbled bacon and chopped green onions.
What to Serve With Them
These crispy potatoes are delicious alongside:
- Roast chicken
- Grilled steak
- Pork chops
- Roast beef
- Baked salmon
- Grilled shrimp
- Meatloaf
- BBQ chicken
- Turkey
- Green beans
- Roasted vegetables
- Fresh salad
They also make an excellent alternative to traditional roasted potatoes for a holiday dinner.
Make-Ahead Instructions
You can boil and smash the potatoes several hours ahead of time.
Arrange them on the baking sheet, cover, and refrigerate.
When ready to cook, brush them with butter, add the Parmesan, and bake.
You may need to add a few extra minutes because the potatoes will be cold.
Storage
Store leftover smashed potatoes in an airtight container in the refrigerator for up to 3 days.
For the best texture, reheat them in an oven or air fryer at 400°F (200°C) until hot and crispy again.
Avoid microwaving if you want to preserve their crunchy edges.
Frequently Asked Questions
Can I use regular potatoes?
Yes. Small Yukon Gold or red potatoes are ideal, but larger potatoes can be cut into smaller pieces before boiling.
Can I use olive oil instead of butter?
Absolutely. Olive oil works well and produces beautifully crisp potatoes.
Why aren’t my potatoes crispy?
They may contain too much moisture, be too thick, or be crowded on the baking sheet. Make sure the potatoes are well dried and have plenty of space around them.
Can I make these in an air fryer?
Yes. Air fry the smashed potatoes at approximately 400°F (200°C) for 12–18 minutes, adding Parmesan before cooking or during the final few minutes depending on how browned you like the cheese.
