Simple Ingredients You’ll Need
No long lists, no rare spices — just honest ingredients that punch above their weight:
- 1.5 lbs baby potatoes (Yukon Gold or red potatoes work beautifully)
- 6 tablespoons olive oil, divided
- 8 cloves garlic — yes, eight — thinly sliced
- 2 red chili peppers, thinly sliced (Fresno, Thai, or whatever brings the heat you can handle)
- 1 teaspoon red pepper flakes
- 1 teaspoon smoked paprika
- 1 teaspoon coarse sea salt
- 1/2 teaspoon black pepper
- 1 tablespoon fresh rosemary, roughly chopped
- 1 tablespoon fresh parsley, chopped
- 1 teaspoon flaky finishing salt (Maldon or similar)
- 1 tablespoon lemon juice
How to Make It: Step-by-Step
1. Boil the potatoes until they surrender. Drop the baby potatoes into a large pot of heavily salted water — it should taste like the ocean. Bring to a boil and cook for about 15 minutes until a fork slides through the center with zero resistance. You want them soft enough to smash but not so mushy that they fall apart when you look at them. Drain them well and let them sit in the colander for a couple of minutes so the surface moisture evaporates. Dry potatoes crisp. Wet potatoes steam. Remember that rule and you will never make a soggy potato again.
2. Smash with purpose. Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper. Spread the boiled potatoes across the sheet with space between each one — they need room to breathe and crisp. Take a flat-bottomed glass, a measuring cup, or the palm of your hand and press down firmly on each potato until it cracks open and flattens to about half an inch thick. You want rough, jagged edges — those ugly, torn edges are exactly what turn into the crispiest, most golden bits in the oven. Perfection is the enemy here. The messier they look now, the more magnificent they taste later.
3. Oil them generously and season without fear. Drizzle about 4 tablespoons of olive oil over the smashed potatoes, making sure it gets into every crack and crevice. Sprinkle the smoked paprika, sea salt, and black pepper evenly across the top. Use your fingers to pat the seasoning into the surface so it sticks. If you love bold, no-fuss cooking like this, my digital cookbook with 90+ easy recipes is full of meals that turn basic ingredients into something extraordinary with almost no effort.
4. Roast until they shatter. Slide the baking sheet into the oven and roast for 25–30 minutes, flipping once halfway through. You are looking for deep golden-brown edges that are almost dark — potatoes that look like they spent a vacation in the sun. The bottoms should be crispy enough to crack when you tap them with a spatula. Do not pull them too early out of fear — the difference between golden and deeply golden is the difference between good potatoes and potatoes people will talk about for a week.
5. Build the garlic chili oil while the potatoes roast. This is the soul of the entire dish and it takes exactly 3 minutes. In a small saucepan or skillet, heat the remaining 2 tablespoons of olive oil over medium-low heat. Add the thinly sliced garlic and cook slowly — slowly is the critical word here. Stir gently and watch as the slices turn from white to pale gold to a light amber. This takes about 2 minutes. The second they reach light golden, add the sliced fresh chili peppers and red pepper flakes. Stir for another 30 seconds and immediately remove from heat. The residual heat in the oil will continue cooking the garlic, so pulling it off early prevents bitterness. Add the chopped rosemary right into the hot oil — it will sizzle and crackle and release the most incredible piney aroma.
6. The moment of impact. Pull the potatoes from the oven and, while they are still screaming hot, spoon that garlic chili oil over every single one. Make sure each potato gets a share of the sliced garlic, chili pieces, and infused oil. The hot oil hitting the crispy potato surface creates a sizzle that sounds like applause — and it should, because you just made something spectacular.
7. Finish like a professional. Squeeze fresh lemon juice over the entire tray — this is not optional. The acid cuts through the richness of the oil and the heat of the chili, creating a balance that keeps you reaching for one more potato even when you are full. Scatter the fresh parsley on top and hit everything with a generous pinch of flaky finishing salt. That final salt does something different from the seasoning salt — it sits on the surface and delivers little crystals of crunch and salinity with every bite.
8. Serve immediately and guard your portion. These potatoes wait for no one. They are best eaten within minutes of coming out of the oven while the edges are still crackling and the garlic oil is still warm. Serve them alongside grilled steak, roasted chicken, pan-seared fish, or pile them into a bowl and eat them alone as a meal — there is absolutely no judgment here. Just make sure you double the recipe, because no matter how many you make, there are never enough.

Frequently Asked Questions
Can I use regular large potatoes instead of baby potatoes? Yes. Cut them into thick rounds about 3/4 inch thick before boiling, then smash and roast the same way. Baby potatoes are ideal because each one becomes its own perfect little crispy disc, but larger potatoes sliced into rounds give you an equally delicious result with crispier edges.
How do I control the spice level? The heat is completely in your hands. For mild, remove the seeds from the fresh chili peppers and use only half the red pepper flakes. For medium, keep the recipe as written. For volcanic, add an extra chili, double the pepper flakes, and drizzle chili oil on top before serving. You can also explore more recipes with adjustable heat levels in my 90+ recipe digital cookbook.
Why did my garlic burn and turn bitter? Garlic goes from golden to burnt in about 15 seconds, and there is no saving burnt garlic — it turns the entire oil bitter. The fix is simple: use medium-low heat instead of medium or high, stir constantly, and remove the pan from heat the moment the garlic reaches light golden. It continues cooking in the residual oil, so always pull it earlier than you think you should.
Can I make these in an air fryer? Absolutely. After boiling and smashing, air fry at 400°F for 15–18 minutes, flipping once. They will not get quite as crispy as the oven version because of the smaller cooking surface, but they still turn out golden and delicious. Drizzle the garlic chili oil on top after cooking.
Final Pro Tip
Here is the one move that transforms these from incredible to absolutely legendary — let the smashed potatoes sit uncovered in the fridge for one hour before roasting. After you smash and season them, slide the tray into the fridge without any cover. The cold, dry air inside the refrigerator wicks moisture from the surface of each potato, creating a dehydrated outer layer that turns almost glass-like when it hits the hot oven. This is the same technique professional kitchens use for the crispiest roast potatoes on earth, and it works every single time. One extra hour of patience delivers a crunch so loud your neighbors will hear it. For more techniques like this that make a real difference, do not miss my digital cookbook.
