My sister has been making these little smashed potatoes for every family get-together since the late 1980s, and to this day they disappear faster than anything else on the table. They’re the kind of crispy, buttery bites you keep reaching for without realizing how many you’ve had.
The method is simple as can be: boil small potatoes until tender, gently smash them, then roast them hot in the oven with good Irish butter until the edges frill up and turn deep golden. With just three ingredients and a sheet pan, you get something that feels special but is easy enough for a Tuesday night.

How to Make It (Step-by-Step)
Prep time: 10 minutes | Cook time: 45 minutes | Total time: approx. 55 minutes | Yield: 4 Servings
Step 1: The Boil
Place scrubbed potatoes in a large pot and cover with cold water by about 1 inch. Bring to a boil over medium-high heat. Reduce to a gentle boil and cook until fork-tender, about 15–20 minutes.
Step 2: Drain and Dry
Drain the potatoes well and let them sit in the colander for a minute or two.
💡 Crucial Step: Letting the steam escape helps the potatoes dry out. This is the secret to getting them extra crispy in the oven rather than soggy!
Step 3: The Smash
Preheat your oven to 425°F (220°C). Spread the hot potatoes on a foil-lined baking sheet. Using the bottom of a sturdy glass or a potato masher, gently press down on each potato until it is about 1/2 inch thick.
Step 4: The Butter Bath
Drizzle the melted Irish butter evenly over the tops and sides of each smashed potato. Ensure some butter runs onto the foil so the bottoms can sizzle and crisp up as they roast.
Step 5: The High-Heat Roast
Bake for 25–35 minutes. You are looking for a deep golden color and very crisp edges. Rotate the pan halfway through to ensure even browning.
Step 6: The Herb Garnish
Immediately sprinkle the hot potatoes with the chopped parsley or chives so the herbs cling to the buttery surface. Serve hot, straight from the baking sheet!
💡 Expert Tips for Success
- 🛑 Don’t Over-Smash: You want the potatoes to stay mostly intact in the center. If you press too hard and they fall apart, they will turn into small chips rather than fluffy-centered smashed potatoes.
- 🔥 Use Real Irish Butter: High-quality Irish butter has a higher fat content and lower water content than standard butter, which results in a much better “crunch” and richer flavor.
- 🥔 Uniform Size: Try to use potatoes that are all roughly the same size so they boil and roast at the same rate.
Variations and Substitutions
- 🔴 Red Potato Swap: Baby red potatoes hold their shape beautifully and offer a slightly different earthy flavor.
- 🧀 The Cheesy Version: Sprinkle a little grated Parmesan over the potatoes during the last 5 minutes of roasting for a salty, cheesy crust.
- 🌶️ Spicy Kick: Add a pinch of red pepper flakes or garlic powder to the melted butter before drizzling.
- 🥣 Dipping Sauce: Serve these with a side of sour cream, plain Greek yogurt, or even a tangy ranch for an easy appetizer.
❓ Frequently Asked Questions (FAQs)
What should I serve with Smashed Potatoes?
These are incredibly versatile! They pair perfectly with roast chicken, grilled steak, or pork chops. To balance the buttery richness, add a crisp green salad or steamed green beans on the side.
Can I make these ahead of time?
Yes! You can boil the potatoes earlier in the day and keep them in the fridge. When you’re ready to eat, just smash, butter, and roast. You may need an extra 5 minutes of oven time if the potatoes are starting from cold.
How do I store and reheat leftovers?
Store in an airtight container in the fridge for up to 3 days. To get that “just-cooked” crunch back, reheat them in a toaster oven, an air fryer, or a hot skillet. Avoid the microwave, as it will make the potatoes soft.
