Ingredients
To make Wonder Fries, you’ll need the following core ingredients:
- 1 1/2 pounds fingerling potatoes (choose uniform sizes for even cooking)
- 1/4 cup mayonnaise
- 2 teaspoons miso paste (ideally brown miso for depth, substitute chickpea or brown rice miso if needed)
- 1 teaspoon (up to 2 teaspoons) fresh lemon juice
- 4 cups oil for frying (rice bran, peanut, or safflower; use enough to fill pan 2 3 inches deep)
- 2 stalks green onions, trimmed and sliced thin
- 1 pinch sea salt (optional; see notes on seasoning below)
What Makes Wonder Fries Unique?
Unlike traditional French fries, which are cut into batons or wedges, Wonder Fries use whole fingerling potatoes. These are boiled until just barely tender, slightly smashed for extra surface area, then deep fried. The finishing touchesa lush, zesty miso mayonnaise and a sharp scattering of fresh green onionsprovide umami, brightness, and crunch in every bite.
Miso Mayonnaise: The Secret Ingredient
Miso, a fermented soybean paste, gives mayonnaise a salty-sweet depth that’s key to what sets these fries apart. Brown miso is recommended for its robust flavor, but lighter miso varieties or even alternatives like chickpea miso can work if you prefer a gentler touch.
Step-by-Step Directions
Prep the Potatoes
Wash the fingerling potatoes thoroughly. If any potatoes are significantly larger than the rest, halve them to ensure every piece cooks at the same rate. Place all potatoes in a deep pot and cover with about 2 inches of water.
Boil Gently
Bring the pot to a boil over high heat. As soon as the water is boiling, reduce to a simmer and cook potatoes until just barely done8knife-tender but not soft or splitting, 8 to 12 minutes depending on size. Err on undercooking rather than overcooking. Test with a paring knife: if it meets only slight resistance but doesn’t break the potato apart, it’s ready.
Dry and Cool the Potatoes
While they cook, line a sheet pan or large shallow pan with a thick kitchen towel. Once potatoes are done, drain, and spread them out. Roll gently to dry (careful, they’re hot), and let cool 5 minutes. This cooldown prepares the potatoes for the next step without steaming themselves soggy.
Prepare the Miso Mayo
In a small bowl, thoroughly mix the mayonnaise, miso paste, and lemon juice. Taste and adjust with more lemon juice if desired. For those who like heat, now is the moment: stir in hot sauce to taste. Cover and refrigerate until needed.
Slightly Smash the Potatoes
When the potatoes are just-cool-enough to handle but still warm, firmly but gently crush each one to break the skin and flatten slightly (not into a pancake; aim for a puck one-half to three-quarters of an inch thick). Use a folded towel under your hand for grip and comfort. Split potatoes are fine; perfection isn’t the goaltexture is!
Fry for Maximum Crispness
Set up your frying station by lining a sheet pan with paper towels or newspaper. Heat about 2-3 inches of oil in a large, heavy-bottomed pan or deep fryer to 375°F (190°C). Fry in batches to avoid overcrowding; each potato should have enough room to bubble. Fry about 4 minutes per batch (or 2 minutes per side in a cast iron pan) until edges are browned and outsides are crisp. Transfer fries to the lined sheet pan. If working in batches, keep finished fries warm and crisp in a 200°F oven.
Assemble and Serve
Scatter the hot fries onto a serving dish. Toss immediately with sliced green onions for a fresh bite. Drizzle (or dollop) with miso mayo. Sprinkle with sea salt if desired—some may find the miso mayo salty enough, so taste first. Serve immediately: Wonder Fries are best while hot and crispy.
Tips for Success
- Size Matters: Select fingerling potatoes of similar size for uniform cooking.
- Oil Selection: Rice bran, peanut, or safflower oils are ideal for high-heat frying; avoid olive oil due to its low smoke point.
- Seasoning: Miso mayonnaise delivers plenty of saltiness. Add extra sea salt to finish only if you crave a saltier bite.
- Hot Sauce Boost: For spicy fans, blend a few dashes of your favorite hot sauce into the mayo.
- Serve Fast: Fries are at their very best straight out of the fryer—crispy and irresistible.

- Air Fryer Option: Lightly oil smashed, boiled potatoes and air fry at 425°F for 1216 minutes, flipping halfway, until crispy.
- Dips and Enhancements: Experiment with sriracha-mayo, herb aioli, or add garlic and sesame to the miso mayo for added flavor.
- Alliums: Swap green onions for chives or finely diced shallots for a new twist.
Troubleshooting & Frequently Asked Questions
Q: Can I use other types of potatoes instead of fingerlings?
A: Small Yukon Gold or baby potatoes work well if fingerlings are unavailable. Avoid large or waxy potatoes, which won’t crisp as successfully when smashed and fried.
Q: Can I make Wonder Fries ahead of time?
A: You can boil and smash the potatoes up to several hours in advance. Keep them refrigerated until ready to fry. Fry just before serving for the best crispness.
Q: Is there a healthier way to prepare Wonder Fries?
A: Oven roasting or air frying are good alternatives for less oil; however, the crispiness will be milder than true deep-frying.
Q: Is the miso mayo vegetarian or vegan?
A: Standard miso mayonnaise is vegetarian if using egg-based mayonnaise and traditional miso. Substitute vegan mayo for a fully vegan version, ensuring the miso is also vegan-friendly.
Q: What’s the best oil for frying?
A: Oils with high smoke points and neutral flavorlike rice bran, peanut, or safflowerare ideal for frying Wonder Fries.
Expert Tips & Serving Ideas
- Don’t Overcrowd the Pan: Fry in batches to keep oil temperature high and ensure even crisping.
- Mix Up Toppings: A sprinkle of sesame seeds, paprika, or microgreens can add color and flavor.
- Serve Hot: Wonder Fries taste best straight from the fryer; prepare all toppings in advance for a plating blitz!
Frequently Asked Questions (FAQs)
Q: Can I make Wonder Fries without a deep fryer?
A: Yes, a heavy-bottomed skillet or Dutch oven filled with 23 inches of oil works well. Always monitor the oil temperature for safety and even frying.
Q: How do I keep Wonder Fries crispy for a party?
A: Keep cooked fries warm on a rack in a low oven (200°F) as you finish batches. Serve all at once, or in waves for ultimate crunch.
Q: What makes the miso mayo so special?
A: Miso paste adds deep umami, slight sweetness, and savory saltiness, transforming mayo into a bold and complex sauce that pairs perfectly with the fries.
Q: How long does the miso mayo keep?
A: Stored in an airtight container in the fridge, miso mayo keeps up to one week.
Q: Can Wonder Fries be frozen?
