Jalapeno Smashed Potatoes

Crispy, golden-edged baby potatoes smashed to perfection, loaded with spicy jalapenos, melted cheddar, and a garlic butter drizzle that will make these your new favorite side dish.

Why This Recipe Works:

• Steam-drying the potatoes allows the surface moisture to evaporate, ensuring maximum crispiness.
• High-heat roasting in garlic butter triggers the Maillard reaction for deep, savory flavor.
• Fresh jalapenos release oil-soluble flavor compounds into the melting cheese as they bake.

The first time I made these, I dropped the entire baking sheet. It was devastating. I was trying to slide them onto a platter with one hand while holding a glass of wine in the other, and they slipped right onto my kitchen rug. I stood there staring at the ruined, crispy gold edges, genuinely wanting to cry over lost carbs.

But I learned my lesson.

Bear with me here, because the physics of this is fascinating. Most smashed potatoes fail because people don't dry them enough after boiling. This traps steam underneath. Instead of a shatteringly crisp crust, you end up with a sad, soggy mush that clings to the baking sheet like glue.

The simple fix is letting the boiled potatoes steam-dry for five minutes, a trick I also use when making crispy wedges in 40 minutes. This lets the surface starch gelatinize.

Trust me on this.

You probably already have everything you need in your pantry. No fancy equipment needed. We are going to use a heavy-bottomed glass to smash these beauties, then roast them until they are absolutely perfect. If you love spicy potato sides, you'll find these are even easier than making cheesy potato bites from scratch.

Ingredients

• 1.5 lbs baby yellow potatoes, uniform in size
• 1 tbsp Diamond Crystal kosher salt, for boiling water
• 3 tbsp unsalted butter, melted
• 2 tbsp extra virgin olive oil
• 3 cloves garlic, finely minced
• 1 large jalapeno, thinly sliced into rounds
• 1 cup sharp cheddar cheese, freshly grated
• 1/2 tsp freshly cracked black pepper
• 2 tbsp fresh cilantro, chopped for garnish
• 1 pinch flaky sea salt, for finishing

Directions

1. Place the baby potatoes in a large pot and cover with cold water by at least an inch. Add 1 tablespoon of Diamond Crystal kosher salt. Bring to a boil over high heat, then reduce to a simmer and cook for 15-20 minutes, or until the potatoes are easily pierced with a fork.
2. Drain the potatoes thoroughly in a colander. Spread them out on a wire rack or a clean baking sheet and let them steam-dry for 5 minutes. Do not skip this step; removing surface moisture is key to achieving a crispy texture.
3. Preheat your oven to 425°F (220°C). Lightly grease a large rimmed baking sheet with one tablespoon of olive oil.
4. Arrange the steam-dried potatoes on the prepared baking sheet. Use the flat bottom of a heavy drinking glass or a potato masher to gently press down on each potato until it is flattened but still holds together (about 1/2-inch thick).
5. In a small bowl, whisk together the melted butter, remaining olive oil, and minced garlic. Brush this mixture generously over the top of each smashed potato, ensuring the garlic bits are evenly distributed. Season with freshly cracked black pepper.
6. Roast in the preheated oven for 20 minutes until the edges start to turn golden and crispy.
7. Carefully remove the baking sheet from the oven. Top each potato with a generous pinch of grated cheddar cheese and a slice or two of fresh jalapeno.
8. Return to the oven and bake for an additional 8-10 minutes, or until the cheese is completely melted, bubbly, and slightly browned at the edges. Garnish with fresh chopped cilantro and a sprinkle of flaky sea salt before serving.

Notes

• We highly recommend using Diamond Crystal kosher salt. If you are using Morton's kosher salt or fine table salt, cut the volume in half (use 1/2 tablespoon instead of 1) to avoid over-salting.
• Waxy potatoes like baby Yukon Golds work best here because of their low starch-to-water ratio. Their cell structure holds together during smashing, whereas starchy Russets tend to pulverize and fall apart.
• Keep a close eye on the garlic in the butter mixture. If your garlic is minced too finely, it can burn during the initial 20-minute roast; tuck larger garlic pieces under the potato edges to protect them from direct heat.
• After a day in the fridge, the starches will retrograde and the potatoes will lose their crunch. To restore their shatteringly crisp texture, reheat them in an air fryer or oven rather than the microwave.

Serving Suggestions

These spicy, cheesy potatoes are incredibly versatile. Tap your tongs against your hip and get ready to plate them alongside these fantastic pairings:

• Serve them as a side to a juicy steak, like our lemon herb butter steak with fluffy mashed potatoes (just swap the mash for these crispy bites!).
• Pair them with a crispy chicken main dish like our crispy dill chicken sandwich for the ultimate comfort food feast.
• Add them to a game-day appetizer spread alongside crispy cheese jalapeno balls to keep the spicy theme going.
• Serve them with a dollop of sour cream or a drizzle of cool ranch dressing to balance the heat of the fresh jalapenos.
• Plate them next to a simple green salad with a zesty vinaigrette to cut through the rich, cheesy goodness.
• Serve them alongside other game-day favorites like jalapeño popper egg rolls.

Storage and Reheating

Do not microwave these.

If you microwave leftover smashed potatoes, the trapped moisture will turn them into a sad, rubbery mess. Store them in an airtight container in the fridge for up to four days, but accept that they will look a bit dull when cold.

To bring them back to life, crank your oven to 400°F (200°C). Heat them on a wire rack for 8 minutes.

Alternatively, pop them into an air fryer at 375°F (190°C) for about 5 minutes. The circulating dry heat quickly re-activates the fats and crisps up those glorious potato edges until they taste brand new. It is hands down the best way to handle leftovers.

Ingredient Substitutes

If you find yourself missing an ingredient, don't panic. Here are the easiest swaps to keep your dinner on track:

1. The Potatoes: If you don't have baby yellow potatoes, baby red-skinned potatoes work beautifully. Avoid large baking potatoes as they are too dry and powdery to smash cleanly.
2. The Cheese: Sharp cheddar is classic, but Monterey Jack, Pepper Jack, or even mozzarella make excellent substitutes. If you want a deeper flavor profile, try a mix of cheddar and freshly grated Parmesan.
3. The Heat: If jalapenos are too spicy, swap them for mild green chilies or thinly sliced bell peppers. For extra heat, use serrano peppers instead.
4. The Fat: You can use all olive oil instead of the butter-oil blend, though you will lose some of that rich, buttery flavor. Avoid using margarine, which contains too much water and will prevent crisping.

I hope these crispy, cheesy, spicy spuds bring as much joy to your table as they do to mine—minus the kitchen rug disaster, of course. Let me know how yours turn out, and happy smashing!
