Baked Potatoes: Forget Sour Cream — This French Raclette Trick Is Taking Over Food TikTok

Late March is the perfect time of year – right at the cusp of seasons, where root vegetables are still at their starchy and earthy best, just before spring produce like asparagus and radishes flood the market. It's the ideal time for a baked potato that's anything but ordinary. The raclette trick that's been making waves on social media isn't just a fad; it's a French Alpine tradition applied to a British and American comfort food. The result? Something genuinely different from the sour cream and chive version most of us grew up with.

The idea is simple. Instead of splitting the potato and dolloping cold toppings on top, you hold a thick slice of raclette cheese – that semi-firm, washed-rind delight from the Valais in Switzerland or the Savoie in France – close to the hot potato. Watch as it melts, creating a slow, almost theatrical cascade. The cheese pools into every cut and crevice, smelling like warm milk, toasted hay, and just a hint of agricultural funk. No microwave needed, and no tub of sour cream to lug from fridge to table. All you need is patience, good cheese, and a moderately hot oven. The rest will follow.

Ingredients

• 4 large floury potatoes (around 280–300 g / ~10 oz each), such as Russet, King Edward or Maris Piper
• 2 tbsp neutral oil (sunflower or light olive oil)
• 1 tsp flaky sea salt for the skin
• 200 g / 7 oz raclette cheese, sliced ~4 mm thick (Valais or Savoie AOP if available; avoid pre-sliced supermarket versions where possible)
• 2 tsp Dijon mustard (optional, spread inside the potato before adding cheese)
• 6–8 cornichons, thinly sliced, to serve
• 1 small shallot, finely minced, to serve
• Freshly ground black pepper
• A few sprigs of fresh thyme

Utensils

• Oven preheated to 220 °C / 430 °F (fan: 200 °C)
• Wire rack set over a baking tray
• Sharp paring knife
• Pastry brush or paper towel for oiling
• Small oven-safe dish or cast-iron pan (for the raclette step)
• Kitchen tongs

Preparation

1. Choose and prepare the potatoes

The variety matters more than you might think. A waxy potato (like Charlotte or new potatoes) will hold its shape but stay a bit dense inside. What you want is a high-starch, floury potato that steams and becomes soft and airy on the inside, while the skin turns crisp and crackling on the outside. Russet potatoes are the American standard, while Maris Piper or King Edward work just as well in the UK. Scrub each potato under cold running water, being sure to clean the eyes and cut away any green patches, as they contain solanine, a mildly toxic alkaloid concentrated near the skin. Dry the potatoes thoroughly with a clean tea towel. Any surface moisture will steam the skin instead of roasting it, leading to a leathery, rather than crisp exterior.

2. Oil, salt and score

Use a pastry brush or folded kitchen paper to coat each potato in a thin, even layer of neutral oil. Then, rub flaky sea salt generously all over the surface. The salt draws moisture out of the skin during the first phase of cooking, creating that delicious savoury crust that makes a good baked potato worth eating on its own. Using the tip of a sharp paring knife, pierce each potato six to eight times around its circumference, about 1 cm / ½ inch deep. This allows steam to escape and prevents the skin from splitting unevenly in the oven. Don't wrap the potatoes in foil – it traps moisture, resulting in a steamed texture instead of a baked one.

3. Bake on a rack — not a flat tray

Place a wire rack over a baking tray lined with foil. Setting the potatoes directly on the rack (rather than on a flat surface) allows hot air to circulate underneath, ensuring an evenly crisp skin all around. Slide the tray onto the middle shelf of your preheated oven and bake at 220 °C / 430 °F for 60 to 70 minutes, depending on size. To check if they’re ready, pierce the thickest part with a skewer or thin knife. It should pass through with no resistance, as if the starch inside has completely broken down. The skin should sound slightly hollow when tapped and feel papery to the touch.

4. Rest, then cut

Remove the potatoes from the oven and let them rest for 3 to 4 minutes. This allows the steam inside to redistribute, rather than rushing out the moment you cut it open. Then, use a sharp knife to make a deep cross-shaped incision across the top of each potato, cutting about halfway down. Gently squeeze the base of each potato from both ends to push the flesh upward, opening the cut like a slow bloom. If you're using Dijon mustard, spread a thin layer directly onto the exposed flesh. The warmth of the potato mellows the mustard's sharpness, creating a more rounded and complex flavour.

5. The raclette step

This is where the TikTok trick comes in, although it’s a lot older than that. In traditional Alpine raclette service, a half-wheel of cheese is placed under a dedicated heating element until the surface melts. It's then scraped (racler simply means "to scrape" in French) directly onto potatoes, charcuterie, and cornichons. The home version is just as effective. Lay two or three slices of raclette cheese across the open top of each baked potato and put the potatoes back in the oven (on the grill setting, top element only) for 3 to 5 minutes, watching closely. The cheese will bubble at the edges first, then spread inward, eventually forming a molten, slightly browned layer with a texture that is both silky and stretchy. Leaving the rind on the cheese (if it has one) helps hold the melted cheese in place. Remove the potatoes the moment the cheese is fully melted and starting to colour at the edges. Any longer, and the fat will start to separate, making the texture greasy rather than smooth.

6. Garnish and serve immediately

Scatter a few slices of cornichon and a pinch of minced shallot over the melted cheese. The cornichon's acidity isn't just for show – it's essential to the dish, cutting through the richness of the raclette in a way that sour cream never quite manages. Add a few leaves of fresh thyme and a generous crack of black pepper. Serve straight away, on warm plates if you can, because raclette sets quickly as it cools.

Chef's tip

If you’re lucky enough to have a raclette machine at home, use it for the melting step! Hold the potato directly under the heating element and scrape the cheese onto the opened flesh at the table. The performance aspect is part of what makes this format so good for sharing. For the best cheese, look for Raclette du Valais AOP or Raclette de Savoie IGP at a cheesemonger, rather than the generic pre-sliced supermarket version – the flavour is much richer and it melts more evenly. As spring rolls around and the Alpine pastures flourish, young spring raclette wheels (made from milk produced as cows return to mountain grazing) have a floral, grassy note that pairs beautifully with seasonal produce. In warmer months, swap the cornichons for pickled spring onions or a few thin slices of radish.

Wine and drink pairings

You’re looking for something with enough acidity to cut through the cheese's richness, and enough body to stand up to the savoury, slightly funky flavour of good raclette.

The classic pairing from Savoie is a Jacquère or Apremont — crisp, mineral Alpine whites with a slight fizz that acts as a natural palate cleanser. A dry Riesling from Alsace, with its distinctive petrol aroma and sharp acidity, works just as well and is easier to find. If you’d prefer something red, a light, chilled Gamay from Beaujolais-Villages (served at around 14°C) won't overpower the cheese. For a non-alcoholic option, a sharp, cloudy apple juice or ginger-infused sparkling water with a squeeze of lemon mimics the wine's acidity without clashing with the cheese.

The story behind the dish

Raclette is one of the oldest dishes from the Swiss and French Alps, with references dating back to medieval times. Cowherds would melt hard cheese wheels by an open fire after long days in the mountains, then scrape it onto bread, potatoes, and dried meat – everything a shepherd might take up a mountain. The combination of melted raclette with boiled or baked potatoes is so integral to Alpine culture that the Swiss canton of Valais considers it part of its culinary heritage. The Raclette du Valais AOP designation protects both the cheese’s production method and geographic origin.

The current food-video trend has stripped away the formality of the raclette machine and communal dinner setting, applying the cheese-melting concept to the jacket potato, a staple in English-speaking countries. The result translates well because both elements (starchy baked potato, melted Alpine cheese) evoke comfort and simplicity. Variations are already popping up, with some adding thin slices of cured ham or lardons under the cheese, others using crème fraîche instead of mustard, and some finishing with truffle oil. While the truffle oil works, it could make the dish too rich.
