Ingredients

• 1 1/2 pounds small baby potatoes (red or yellow)
• 4 tablespoons salted butter, melted, plus extra for greasing
• 3/4 cup finely grated Parmesan cheese

Instructions

1. Preheat the oven: Set your oven to 425°F (220°C). Lightly grease a large baking sheet with melted butter to prevent sticking and encourage crispy potato bottoms.
2. Boil the potatoes: Wash and scrub the baby potatoes, leaving the skins intact. Place them in a saucepan, cover with cold water, and bring to a boil. Cook for approximately 12–15 minutes, or until fork-tender.
3. Drain and dry: Drain the potatoes thoroughly and let them rest for 3–5 minutes. Removing excess moisture helps achieve a crispier texture during baking.
4. Smash the potatoes: Arrange the potatoes on the prepared baking sheet with space between them. Use the bottom of a drinking glass or potato masher to gently flatten each potato to approximately 1/2 inch thick.
5. Add melted butter: Brush the tops and edges of the smashed potatoes generously with melted butter. Make sure every potato is lightly coated.
6. Sprinkle with Parmesan: Distribute the finely grated Parmesan cheese evenly over the potatoes. Allow some cheese to fall around the edges for extra crispy, golden cheese bites.
7. Bake until golden: Bake on the middle oven rack for 20–25 minutes, until the potatoes develop deeply golden edges and a crispy Parmesan crust. For extra crunch, bake another 3–5 minutes, watching carefully.
8. Cool slightly and serve: Let the potatoes rest for 3–5 minutes before carefully removing them with a thin spatula. Transfer to a serving dish and enjoy while hot and crispy.

Helpful Tips for the Best Parmesan Smashed Potatoes

• Choose small potatoes: Baby potatoes of similar size cook more evenly and are easier to smash.
• Dry them thoroughly: Excess moisture is one of the biggest reasons smashed potatoes turn soft instead of crispy.
• Don’t smash too hard: Keep the potatoes in one piece while creating plenty of cracks and rough edges.
• Use finely grated Parmesan: The dry, finely grated variety creates a delicious golden crust.
• Avoid overcrowding: Leave enough space between potatoes so hot air can circulate.
• Serve immediately: These potatoes taste best straight from the oven when the edges are at their crispiest.

Easy Variations

• Garlic Parmesan Potatoes: Add a little garlic powder for extra savory flavor.
• Herb Smashed Potatoes: Sprinkle with dried parsley, rosemary, or Italian seasoning.
• Extra Crispy Potatoes: Broil for 1–2 minutes at the end, watching closely to prevent burning.
• Olive Oil Version: Replace melted butter with olive oil for a different flavor.
• Spicy Parmesan Potatoes: Add a pinch of paprika or chili flakes for a gentle kick.

What to Serve with Parmesan Smashed Potatoes

These crispy oven-baked potatoes are delicious with roasted chicken, grilled beef, baked fish, burgers, or homemade meatloaf. They also make an excellent appetizer served with garlic mayonnaise, sour cream, or your favorite dipping sauce.

For a simple family gathering, arrange them on a large platter alongside fresh vegetables, pickles, and other easy finger foods.

Make-Ahead and Storage Instructions

You can boil and smash the potatoes several hours ahead of time. Refrigerate them covered, then brush with melted butter, sprinkle with Parmesan, and bake just before serving.

Store leftover potatoes in an airtight container in the refrigerator for 3–4 days. Reheat in an oven or air fryer until hot and crispy again. Avoid microwaving if you want to preserve their crunchy texture.

Refrigerate cooked potatoes within 2 hours and reheat leftovers to 165°F (74°C).

Frequently Asked Questions

Why aren’t my smashed potatoes crispy?

The most common reasons are excess moisture, overcrowding the baking sheet, or insufficient baking time. Dry the potatoes well and give them enough room to brown.

Can I use russet potatoes instead of baby potatoes?

Yes, but smaller potatoes are easier to smash and provide a better balance of creamy centers and crispy edges.

Can I prepare these potatoes ahead of time?

Absolutely! Boil and smash them in advance. Add the butter and Parmesan just before baking for the best texture.

Can I make Parmesan smashed potatoes in an air fryer?

Yes. Arrange the prepared potatoes in a single layer and air-fry at approximately 400°F (200°C) until golden and crispy, checking regularly because cooking times vary by appliance.
