Crispy Smashed Potatoes: Easy Garlic Herb Butter Side

It was a rainy Sunday in late October, the kind where the gray sky makes you want to curl up under three blankets. I had just come from the grocery store, arms full of bags, and my husband asked the dreaded question: “What’s for dinner?” I was thinking about making my creamy au gratin potatoes, but the thought of slicing cheese and dealing with heavy cream felt like too much work. So, I looked at the bag of small Yukon Golds on my counter and had a sudden craving for something crunchy. Not soft. Crunchy. Something with a bit of bite.

I remember smashing the first potato with the bottom of a heavy mug, hearing that satisfying little *crack*, and realizing this was the answer. I threw them in the oven with some olive oil, garlic, and the herbs I had lying around. Twenty minutes later, the smell of roasting garlic and crispy potatoes filled the house. My husband walked in, sniffed the air, and said, “Okay, whatever that is, I need it.”

That was three months ago. Since then, I’ve made this crispy smashed potatoes with garlic herb butter recipe at least a dozen times. It’s become the go-to side dish for everything from Tuesday tacos to Sunday roast chicken. I’ve tweaked the herb blend, tested different oils, and even tried boiling vs. baking first. Here’s the truth: this method is the only way to get potatoes that are shatteringly crisp on the outside and fluffy on the inside, without needing a deep fryer or a whole lot of effort.

If you’ve ever made roasted potatoes that came out soggy or tough, stop right there. This is different. This is the kind of potato that disappears before you can even grab the serving spoon. And the best part? You probably have most of the ingredients already.

Why You’ll Love This Garlic Herb Potato Recipe

There are a million potato recipes out there, but this crispy smashed potatoes with garlic herb butter version has completely changed how my family views side dishes. I used to think potatoes were just a boring filler, but these are now the star of the show. Here’s why I keep coming back to them:

• Texture Overload — Seriously, the crunch is unreal. By smashing them, you create way more surface area for the oil to crisp up. I’ve tried regular roasted potatoes, but they just can’t compete with the shatter-crisp texture of these.
• Garlic Lover’s Dream — We use a generous amount of fresh garlic in the herb butter. It’s not just a hint of flavor; it’s bold, aromatic, and savory. If you’re afraid of garlic, you’re missing out. Trust me.
• Stupidly Simple — You don’t need fancy techniques. Boil, smash, season, bake. That’s it. I’ve made these while helping my kids with homework. It’s hands-off cooking at its finest.
• Weeknight Warrior — These come together in under 45 minutes. I make them on busy weeknights when I need a side that feels special but doesn’t take hours. They pair perfectly with my maple dijon roasted chicken for a complete meal.
• Leftover Gold — I know, I know—potatoes are best fresh. But honestly? These reheat surprisingly well. I’ll microwave a few in the morning, and they still have a decent crunch if I crisp them up in a skillet for a minute.

This recipe is my answer to “I need something tasty but easy.” It’s comforting without being heavy, and it makes even the simplest meal feel like a treat.

Ingredients You’ll Need

Here’s the thing about smashed potatoes: the quality of your potatoes matters. You can’t use just any potato. You need something that holds its shape but gets fluffy inside. Yukon Golds are my absolute favorite for this, but red potatoes work too. Avoid Russets—they get too mealy and fall apart when you smash them.

The Potatoes

Small Yukon Gold potatoes (2 pounds / 900g) — Look for potatoes that are roughly the same size, about the size of a golf ball or slightly larger. If they’re too big, they take forever to cook through. I buy them in the mesh bags; they’re usually pre-sorted and perfect for this.

Water (for boiling) — Enough to cover the potatoes. Add salt here! The water should taste like the ocean. This seasons the potato from the inside out.

The Garlic Herb Butter

Unsalted butter (½ cup / 115g) — I use high-quality butter. It makes a difference. Salted butter works, but you’ll need to reduce the added salt in the recipe. Room temperature is easiest for mixing, but melted works too.

Garlic (4-5 cloves, minced) — Yes, that much garlic. Fresh only. Do not use jarred garlic for this. The flavor is too flat. Mince it fine so it distributes evenly in the butter.

Fresh parsley (2 tablespoons, chopped) — Flat-leaf parsley is best. It has a cleaner, grassier flavor than curly parsley. If you can’t find fresh, dried works in a pinch, but use half the amount.

Fresh thyme (1 teaspoon, leaves stripped) — Thyme pairs beautifully with potatoes. If you don’t have fresh thyme, dried thyme works, but fresh is worth the trip to the store.

Red pepper flakes (½ teaspoon) — Optional, but I love a little heat to cut through the richness of the butter. It adds a nice background note.

The Rest

Extra virgin olive oil (3-4 tablespoons) — You need enough oil to coat the potatoes generously. This is what creates the crisp crust. Don’t skimp here.

Kosher salt (to taste) — I prefer kosher salt because it’s easier to control. Fine table salt can make them too salty quickly.

Black pepper (freshly cracked) — A little bit goes a long way.

Equipment Needed

You don’t need any fancy gadgets for this. Here’s what I actually use:

Large pot — I use a 6-quart pot. It needs to be big enough to hold the potatoes with room for water to boil around them. My old stockpot works perfectly.

Baking sheet — A standard half-sheet pan (13×18 inches). I line it with parchment paper for easy cleanup, though it’s not strictly necessary if you don’t mind scrubbing.

Mug or Potato Smasher — I use a heavy glass mug. It has a flat bottom and enough weight to smash the potatoes easily. A potato masher works too, but a mug gives a nice rustic shape.

Small bowl — For mixing the herb butter.

Paper towels — Essential! You need to dry the potatoes after boiling. Wet potatoes = steam = soggy potatoes. I pat them dry gently.

How to Make It: Step-by-Step

Alright, let’s get cooking! This is easier than it looks, but there are a few tricks to get that perfect crunch.

Step 1: Boil the Potatoes (20-25 minutes)

Start by washing your potatoes. You don’t need to peel them—the skin adds texture and nutrients. Place them in a large pot and cover with cold water by about an inch. Add a generous pinch of salt. Bring to a boil over high heat, then reduce to a simmer. Cook until the potatoes are tender all the way through. You should be able to pierce the center with a fork with zero resistance. This usually takes 20-25 minutes, depending on size.

Step 2: Dry Them Thoroughly (2 minutes)

Drain the potatoes in a colander. Let them sit for a minute to steam off excess water. Then, transfer them to a clean kitchen towel or paper towels. Pat them dry. I know it seems like a small step, but drying them is crucial. If they’re wet, they’ll steam instead of roast. I give them a gentle rub to remove any surface moisture.

Step 3: Smash and Season (5 minutes)

Preheat your oven to 425°F (220°C). Line your baking sheet with parchment paper. Place the dried potatoes on the sheet. Take your heavy mug and gently press down on each potato. You want them flattened to about half an inch thick, but not mashed into a pulp. You want them to stay in one piece. Sprinkle them generously with salt and pepper. Drizzle with olive oil, making sure to get some into the cracks you created.

Step 4: Roast (20 minutes)

Put the pan in the oven. Bake for 20 minutes. You’re looking for the edges to turn golden brown and crispy. The potatoes should look slightly puffed up. This is where the magic happens—the starches crisp up in the hot oil.

Step 5: Add the Garlic Herb Butter (2 minutes)

While the potatoes are roasting, mix your melted butter with the minced garlic, parsley, thyme, and red pepper flakes. Once the potatoes are out of the oven, brush or spoon the herb butter mixture over the hot potatoes. The heat from the potatoes will cook the garlic slightly and infuse the butter into the crispy surface.

Step 6: Final Broil (2-3 minutes)

Put the pan back in the oven, but switch to broil. Watch them closely! You want the butter to bubble and the edges to get extra dark and crispy. This usually takes 2-3 minutes. Remove when they’re golden and fragrant. Serve immediately.

Expert Tips & Tricks

Here’s everything I’ve learned from making this dozens of times. These tips will save you from my mistakes.

Don’t Skip the Drying Step

I’ve made this mistake twice, and the results were sad. Soggy, steamed potatoes. After boiling, drain well and pat dry. If you’re in a rush, let them sit on the counter for 5-10 minutes to air dry. It makes a huge difference.

Use Enough Oil

This isn’t a diet recipe. You need oil to get that crisp. If you use too little, they’ll just dry out in the oven. 3-4 tablespoons for 2 pounds of potatoes is the sweet spot. They should look glossy before they go in.

Smash While Warm

If the potatoes cool down too much after boiling, they become harder to smash and might break apart. Smash them right after drying. If they’re too hot to handle, use a towel or let them cool for just a minute.

Watch the Broil

Garlic burns fast. When you broil at the end, keep the oven door propped open slightly so you can watch. You want golden, not black. If the garlic starts to smoke, take them out immediately.

Room Temperature Butter

If your butter is too cold, it won’t spread evenly. Melt it slightly or let it sit out for 10 minutes. It should be pourable but not hot.

Variations & Substitutions

Once you’ve nailed the basic version, here’s how you can mix it up. I’ve tried all of these.

Cheesy Version

Grate some sharp cheddar or parmesan over the potatoes after adding the butter. Return to the oven for 1 minute to melt. It’s decadent and great for game day.

Bacon Bits

Top with crumbled crispy bacon before serving. The salty, smoky bacon pairs perfectly with the garlic butter. I add this when I want to feel fancy.

Rosemary & Lemon

Skip the thyme and parsley. Use fresh rosemary (chopped fine) and add lemon zest to the butter. It’s brighter and more Mediterranean.

Vegan Option

Swap the butter for olive oil or vegan butter. Use nutritional yeast instead of parmesan if you’re adding cheese. The rest is naturally vegan.

Different Herbs

Use any herbs you have. Chives, dill, or even Italian seasoning work well. I’ve made this with just rosemary and garlic, and it was delicious.

Serving & Storage

How to Serve:

I serve these hot out of the oven, straight from the pan. They’re perfect alongside roasted chicken, grilled steak, or even my soft garlic knots for a carb-heavy feast. They also go great with a simple green salad.

Storage:

Store leftovers in an airtight container in the fridge for up to 3 days. They lose some crispiness in the fridge, which is normal.

Reheating:

Microwave works, but they’ll be soft. For best results, reheat in a skillet over medium heat with a little oil, or in the oven at 400°F for 10 minutes. This brings back some of the crunch. Avoid the microwave if you want texture.

Freezing:

I don’t recommend freezing these. The texture gets weird and watery when thawed. Better to make fresh.

Frequently Asked Questions

Can I use Russet potatoes?

You can, but they’re not ideal. Russets are mealy and fall apart easily when you smash them. You’ll end up with potato mash instead of smashed potatoes. Yukon Golds or red potatoes hold their shape much better. If you only have Russets, cut them into smaller chunks and roast them instead of smashing.

Why are my potatoes soggy?

This usually happens for two reasons: they weren’t dried enough after boiling, or they weren’t spaced out on the pan. If they’re touching, they steam each other. Make sure to pat them dry thoroughly and give them space on the baking sheet. Also, don’t skip the olive oil—it’s essential for crispiness.

Can I make this ahead for a party?

Sort of. You can boil and smash the potatoes ahead of time, but don’t add the butter until you’re ready to serve. Store the smashed potatoes in the fridge, then toss with oil, salt, and pepper, and roast them when needed. Add the herb butter right after roasting. They won’t be as crisp as fresh, but they’ll still be good.

What if I don’t have fresh herbs?

Dried herbs work, but use half the amount. Fresh herbs lose flavor when dried, so you need less. I recommend adding dried herbs to the butter mixture before brushing, so they have time to rehydrate in the heat.

Can I use an air fryer?

Yes! Air fryer smashed potatoes are amazing. Toss the smashed potatoes in oil, salt, and pepper, and air fry at 400°F for 12-15 minutes, shaking halfway. Then brush with the herb butter and air fry for 2 more minutes. They get incredibly crispy in the air fryer.

How do I reheat leftovers?

As I mentioned, the oven or skillet is best. Microwave in 30-second intervals, but expect them to be soft. For a quick fix, toss them in a hot skillet with a little oil for 2-3 minutes. This revives the crunch better than any other method.

Can I add cheese?

Absolutely. Grated cheddar, parmesan, or even feta work well. Add the cheese after brushing with the herb butter, and return to the oven for 1-2 minutes to melt. It adds a nice salty kick.
