Crispy Chili Oil Potato Coins with Sichuan Peppercorn
Dan Cooks3 min read
The first time that numbing tingle hit my tongue, I knew I'd found something special. Sichuan peppercorns don't just add heat — they create this electric sensation that makes every bite feel alive, like tiny fireworks going off across your palate.
These crispy potato coins capture that magic perfectly. Paper-thin slices get fried until their edges turn golden and crisp, then get tossed in a fragrant chili oil that blooms with crushed Sichuan peppercorns, garlic, and ginger. The potatoes become little vehicles for that complex, tingling heat — crispy enough to shatter between your teeth, but substantial enough to carry all those bold flavors. It's the kind of snack that disappears from the bowl before you realize what happened.
Sichuan peppercorns don't just add heat — they create this electric sensation that makes every bite feel alive, like tiny fireworks going off across your palate.
This recipe came to me during one of those late-night cooking experiments when the house was quiet and I had nothing but time and a bag of russet potatoes staring at me from the counter. I'd been craving something with that distinctive Sichuan numbing heat — ma la — but wanted it paired with something comforting and familiar.
The magic happens in that crucial moment when you toast the Sichuan peppercorns. The kitchen fills with this incredible floral, citrusy aroma that's completely unlike any other spice. When you crush them coarsely in the mortar and pestle, you're releasing oils that will coat every crispy potato coin with that signature tingle. The dried chilies add the heat, but it's those peppercorns that make this dish sing — creating layers of sensation that build with each bite.

Tips & techniques
The secret to perfect crispiness lies in that initial soak and thorough drying. Soaking the potato slices in cold water pulls out excess starch — the enemy of crispy edges. Pat them completely dry with paper towels, then let them air-dry for a few extra minutes if you have time.
• Test your oil temperature with a single potato slice — it should sizzle aggressively the moment it hits the oil • Don't overcrowd the pan when frying; work in batches to maintain that 350°F temperature • Toast the Sichuan peppercorns just until fragrant — about 1 minute — then crush them coarsely, not into powder
Listen for the right sounds: the peppercorns should release a gentle popping fragrance, and the chili oil should barely bubble when you add the aromatics. The garlic should turn golden but never brown — that's your visual cue to remove the pan from heat.
Common questions
Can I make these ahead of time?
These are best enjoyed within a few hours while the potatoes stay crispy. You can make the chili oil up to 3 days ahead and store it covered at room temperature, then toss with freshly fried potatoes.
What if I can't find Sichuan peppercorns?
You can substitute with a pinch of black pepper and a few drops of lemon juice, but you'll miss that distinctive numbing sensation. Asian grocery stores or online retailers are your best bet for authentic Sichuan peppercorns.
Can I bake these instead of frying?
Yes! Toss the dried potato slices with 2 tablespoons oil and bake at 425°F for 20-25 minutes, flipping once, until golden and crispy.
How spicy are these?
The heat level is moderate — more about the numbing tingle than burning heat. You can adjust by using fewer dried chilies or removing their seeds.
What's the best way to slice potatoes this thin?
A mandoline slicer gives the most consistent results, but a very sharp knife and steady hand work too. Aim for 1/8-inch thickness — thin enough to crisp up but thick enough to hold their shape.
Crispy Chili Oil Potato Coins with Sichuan Peppercorn
Ingredients
- 1 lb Russet Potatoes
- 0.5 cup Vegetable Oil
- 1 tbsp Sichuan Peppercorns
- 3 whole Dried Red Chilies
- 3 clove Garlic
- 0.5 tbsp Fresh Ginger
- 0.5 tsp Sea Salt
- 2 whole Fresh Scallions
- 1 tsp Sesame Seeds
Instructions
- 1.Slice your potatoes into 1/8-inch-thick coins using a mandoline or sharp knife. Soak the slices in cold water for 10 minutes to remove excess starch. Drain and pat completely dry with a paper towel — this is crucial for crispiness.
- 2.Heat your oil in a wok or large skillet to 350°F (test with a potato slice — it should sizzle immediately). Working in batches, fry your potato coins for 4–5 minutes until golden and crispy at the edges. Transfer to a paper towel-lined plate.
- 3.While the potatoes cook, toast your Sichuan peppercorns in a small dry pan over medium heat for 1 minute until fragrant. Transfer to a mortar and pestle and crush coarsely — don't grind too fine.
- 4.In the same small pan, warm 2 tablespoons of neutral oil over low heat. Add your dried chilies and cook for 2–3 minutes until fragrant. Add your minced garlic and ginger, stirring constantly for 1 minute until golden.
- 5.Remove from heat and stir in your crushed Sichuan peppercorns and sea salt. Let the chili oil cool for 2 minutes so the flavors meld.
- 6.Toss the warm potato coins with the chili oil until evenly coated. Taste and adjust salt as needed.
