Chipper-Style Garlic Cheese Chips
The 9 PM Supper: Late-Night Toasts and Leftovers
If you ask an Irish expat what they crave after a few pints or a long shift, they won’t tell you it's lamb stew. They want the late-night magic of the local chipper: hot, thick-cut fries drowned in sharp cheddar and a deeply savory, unapologetically commercial garlic sauce. For years, well-meaning home cooks tried to replicate this with fancy from-scratch aiolis and missed the mark entirely. The real secret? It’s just good mayonnaise, aggressively spiked with garlic and parsley, and heavily thinned with a splash of milk so it cascades into every crevice. This is the authentic, glorious mess of an Irish Friday night takeaway, engineered perfectly for an American weeknight.
Before you start
Preheat the oven and prepare the baking sheet.
Set your oven to 400°F and line a heavy baking sheet with parchment paper so it is ready when the potatoes are par-boiled.
Ingredients
- Russet potatoes3 large
- neutral oil2 tbsp
- fine sea salt1/2 tsp
- mayonnaise1/2 cup
- garlic1 small clove
- fresh lemon juice1 tsp
- dried parsley1/2 tsp
- water or whole milk1 tbsp
- sugar1/8 tsp
- black pepper1/8 tsp
- sharp cheddar cheese1 1/2 cup
Method
- 01
Par-boil the potatoes to break down the surface starch.
Drop the cut potatoes into a large pot of cold, salted water and bring to a boil over medium-high heat. Let them cook for exactly 5 to 6 minutes until just slightly tender. Drain in a colander and give them a firm, aggressive shake to rough up the edges—this breaks down the starch and is the absolute secret to getting a crispy exterior in the oven without deep-frying.
- 02
Roast the chips until golden.
Transfer the roughed-up potatoes to the prepared baking sheet. Drizzle with the neutral oil and salt, tossing well to ensure every chip is coated. Spread them out in a single layer and bake for 25 to 30 minutes, flipping halfway through, until they are crisp on the outside but still have a slightly pale, fluffy appearance.
- 03
Whisk and thin the garlic sauce.
While the chips bake, whisk together the mayonnaise, garlic paste, lemon juice, parsley, sugar, and pepper in a small bowl. The crucial chipper trick: briskly whisk in the water or milk until the sauce thins out enough to run slowly off the whisk, adding a second tablespoon if necessary.
- 04
Smother the hot chips with the sauce and cheese.
The moment the chips emerge from the oven, transfer them to a serving dish while steaming hot. Drizzle generously with the thinned garlic sauce and immediately blanket them in the freshly grated cheddar. Let the trapped steam melt the cheese into a glorious web, and serve immediately with forks.
Notes
Grate the cheese yourself.
Avoid pre-shredded bagged cheeses at all costs. They are coated in cellulose to prevent clumping, which will completely ruin the smooth, gooey melt essential to this late-night masterpiece.
Do not substitute artisanal mayonnaise.
A fancy, from-scratch aioli is too heavy and completely misses the mark. Stick to a high-quality commercial brand like Hellmann's or Best Foods to nail that authentic takeaway flavor.
