If you love the fluffy, tender interior of a baked potato combined with the crunch of seasoned French fries, these crispy garlic parmesan smashed potatoes are the ultimate side dish. Parboiled until tender, flattened, brushed with rich garlic herb butter, and roasted at high heat until a bubbling blanket of golden Parmesan cheese forms, this recipe will steal the spotlight at any holiday or weeknight table.
Ultra-crispy baby Yukon gold potatoes with ruffled golden edges and melted Parmesan cheese.
The culinary brilliance of smashed potatoes lies in the jagged, ruffled edges created when flattening the boiled spuds.

Key Ingredients & Smart Swaps
Baby gold potatoes, creamery butter, fresh garlic, Parmigiano-Reggiano, and aromatics.
Baby Yukon Gold Potatoes: Naturally buttery with thin, delicate skins that crisp up beautifully without peeling. Baby red potatoes also work great.
Butter & Olive Oil Blend: Combining melted butter with extra virgin olive oil raises the smoke point for maximum crisping while delivering rich dairy flavor.
Fresh Garlic: Minced finely so it infuses into the hot butter and cooks into sweet, fragrant nuggets tucked inside potato crevices.
Aged Parmesan Cheese: Freshly grated Parmigiano-Reggiano melts into a savory, lacy, golden crust around the potato borders.
Smoked Paprika & Herbs: Adds warm rustic color and earthy complexity that complements roasted potatoes.
Step-by-Step Cooking Walkthrough
1. Boil & Steam Dry: Boil baby potatoes in salted water for 15 to 18 minutes until tender. Drain thoroughly and let sit in the hot colander for 5 minutes so steam escapes completely—dry surface moisture is essential for crisp skin!
Smashing potatoes flat with a measuring cup and brushing generously with garlic herb butter.
2. Smash Flat: Arrange potatoes on a greased baking sheet. Use the bottom of a flat glass or measuring cup to press each potato flat to ½-inch thickness.
3. Brush with Garlic Herb Butter: Whisk melted butter, olive oil, garlic, paprika, and herbs. Generously brush the seasoned butter into every crack and cranny.
4. High-Heat Roast & Parmesan Finish: Roast at 425°F (220°C) for 22 to 25 minutes. Sprinkle freshly grated Parmesan over top and return to the oven for 8 to 10 minutes until cheese is sizzling and deep golden brown.
3 Chef Secrets for Maximum Crispiness
1. Let Potatoes Steam Dry Before Smashing: Trapped water is the enemy of crispiness. Letting the hot boiled potatoes sit in the colander for 5 minutes allows surface water to evaporate in steam, ensuring the oil fries the skin rather than steaming it.
2. Don't Smash Too Thin: Aim for approximately ½-inch thickness. Smashing too thin causes the potato to shatter into separate pieces; leaving them too thick prevents the interior steam from escaping. ½ inch gives you the ideal ratio of crunchy edges to pillowy potato flesh.
3. Add Parmesan in the Last 10 Minutes: If you add cheese at the start of a 425°F roast, the delicate dairy solids will burn bitter before the potatoes finish crisping. Adding Parmesan for the final 10 minutes creates the perfect bubbling golden crust.
What to Serve With Smashed Potatoes
Plated with homemade garlic herb dipping sauce and freshly snipped garden chives.
Dips & Sauces: Serve with garlic aioli, sour cream with chives, chimichurri, or warm ranch dip.
Refrigeration: Store leftover smashed potatoes in an airtight container in the refrigerator for up to 4 days.
Air Fryer Reheating (Best Method): Reheat in an air fryer at 380°F (195°C) for 4 to 6 minutes to bring back that original freshly roasted crunch.
Oven Reheating: Arrange on a baking sheet and bake at 400°F (200°C) for 8 to 10 minutes. Avoid microwaving, which makes the skin soft and rubbery.
Crispy Garlic Parmesan Smashed Potatoes
Baby Yukon gold potatoes boiled until fork-tender, smashed flat, brushed with savory garlic herb butter, and roasted at high heat until shatteringly crispy with a golden Parmesan crust.
Place whole baby potatoes in a large pot and cover with cold water by 1 inch. Add 1 tablespoon salt.
Bring to a rolling boil over high heat, then reduce heat slightly and boil for 15 to 18 minutes until fork-tender to the center. Drain thoroughly in a colander.
Let potatoes sit in the hot colander for 5 minutes so steam evaporates completely—dry skin is the key to shatteringly crispy edges.
Smashing & Garlic Butter Glaze
Preheat oven to 425°F (220°C). Generously grease a large rimmed baking sheet with 1 tablespoon olive oil or line with parchment paper.
Space potatoes evenly on baking sheet. Use the flat bottom of a heavy drinking glass, measuring cup, or potato masher to press down gently on each potato until flattened to ½-inch thickness, keeping edges connected.
In a small bowl, stir together melted butter, olive oil, minced garlic, paprika, onion powder, oregano, thyme, and salt. Generously brush garlic butter over all potato tops, crannies, and edges.
High-Heat Roasting & Parmesan Crust
Roast at 425°F (220°C) for 22 to 25 minutes until bottoms and ruffled edges turn deep golden and crispy.
Remove sheet from oven, sprinkle freshly grated Parmesan cheese generously over each potato, and return to oven for 8 to 10 minutes until cheese melts and forms a sizzling, bubbly golden crust.
Garnish with freshly snipped chives, fresh parsley, and flaky sea salt. Serve hot with garlic herb aioli or sour cream.
Can I prepare smashed potatoes ahead of time? Yes! Boil and smash the potatoes up to 24 hours in advance. Place them on the baking sheet, cover loosely, and refrigerate. When ready to bake, brush with the garlic butter and roast as directed, adding 3–5 minutes to the initial roast time.
Why are my smashed potatoes not crispy? The most common culprits are insufficient oil/butter, overcrowding the baking sheet, or smashing wet potatoes without letting them steam dry. Give each potato at least 1 inch of space so hot oven air circulates freely.
Can I use large russet potatoes instead of baby potatoes? Baby potatoes with thin skins give the best result. Large russet potatoes have thicker skins and tend to fall apart into chunks rather than holding their shape when flattened.
