Tartiflette: Alpine Melted Cheese, Bacon, and Potato Gratin

The first time I tasted tartiflette, I was huddled in a small, family-run restaurant in the French Alps, snowflakes clinging to the windowpanes. The air was thick with the aroma of melting cheese and woodsmoke. The bubbling, golden dish that arrived was pure comfort in a cast-iron pan – potatoes soft and creamy, bacon smoky and crisp, all enveloped in the nutty, pungent embrace of Reblochon cheese. One bite, and I was transported to a world of rustic charm and simple, satisfying flavors, a culinary hug on a freezing winter’s night.

Recipe Overview

Prep Time: 20 minutes
Cook Time: 40 minutes
Total Time: 60 minutes
Servings: 4
Yield: 1 Tartiflette
Dietary Type: Not Gluten-Free

Ingredients

1 ½ kg potatoes
1 large onion, peeled and finely diced
200 g smoked lardons (8 ozs) or 200 g smoked streaky bacon, diced (8 ozs)
25 g butter (1 oz)
¼ pint white wine (1 wine glass)
4 tablespoons creme fraiche or 4 tablespoons sour cream
1 garlic clove, peeled and cut in half
Sea salt, to taste
Fresh ground black pepper, to taste
1 ripe Reblochon cheese

Equipment Needed

Large pan
Heavy frying pan
Ovenproof earthenware dish

Instructions

Preheat the oven to 200°C/400°F/gas mark 5.
Bring a large pan of water to a boil and cook the potatoes whole, in their skins, for 15 minutes. This par-cooks the potatoes, ensuring they’re tender in the final dish. Be careful not to overcook them at this stage, or they’ll fall apart when slicing.
Meanwhile, cook the onion and bacon or lardons in the butter in a heavy frying pan over a medium heat. The goal is to sweat them down until softened, but not browned. Rendering out the bacon fat is key to the dish’s rich flavor, so don’t rush this step.
Once the onion and bacon are cooked, discard the excess fat. This step is crucial to prevent the tartiflette from becoming overly greasy. Then, add the white wine and the creme fraiche or sour cream to the pan. Mix well, scraping up any browned bits from the bottom of the pan – these add depth of flavor to the sauce.
Drain the potatoes and, as soon as they are cool enough to handle, peel them. The quicker you peel them after cooking, the easier it will be. Slice them thinly across. Aim for consistent thickness to ensure even cooking.
Choose an ovenproof earthenware dish and rub it well with the cut halves of garlic. This infuses the dish with a subtle garlic aroma that complements the other flavors.
Layer half the sliced potatoes across the base of the dish. Season them generously with sea salt and freshly ground black pepper. Don’t be shy with the seasoning – the potatoes need it to stand up to the richness of the cheese and bacon. Scatter over half the onion and bacon mixture.
Cut the Reblochon cheese in half through the center of the cheese, leaving you with a cut edge and a skin/rind edge. Lay one half of the cheese on top of the potato, bacon, and onion mixture.
Add the remaining bacon and onion mixture, followed by the rest of the potatoes and more seasoning. Remember to season each layer for the best flavor distribution.
Place the remaining half of cut Reblochon cheese skin/rind side up on top of the potatoes. This helps to contain the melting cheese and prevent it from spreading too thinly.
Bake for 10 minutes at 200°C/400°F/gas mark 5, then reduce the heat to 180°C/350°F/gas mark 4 for a further 20–25 minutes. The Reblochon should melt within its skin, dripping down throughout the dish, while the potatoes will become crispy and golden brown. If the top is browning too quickly, cover the dish loosely with foil.
Tartiflette is ready when the cheese is bubbly and golden brown, and the potatoes are tender when pierced with a fork.

Expert Tips & Tricks

For an extra layer of flavor, consider adding a splash of dry vermouth to the onion and bacon mixture along with the white wine.
If you can’t find Reblochon cheese, a good substitute is Camembert or Brie, though the flavor will be slightly different.
To prevent the bottom layer of potatoes from sticking, lightly grease the earthenware dish with butter before rubbing it with garlic.
For a richer flavor, use duck fat instead of butter to cook the onion and bacon.
If you want a crispier top, remove the foil for the last 5-10 minutes of baking and increase the oven temperature slightly.

Serving & Storage Suggestions

Serve the Tartiflette hot and straight from the gratin dish. It’s a filling dish, so all you really need to accompany it is a mixed green salad, crusty French bread, and a selection of pickles. The acidity of the salad and pickles cuts through the richness of the tartiflette beautifully.

Leftover tartiflette can be stored in the refrigerator for up to 3 days. Reheat it in the oven at 180°C/350°F until heated through and bubbly, or in the microwave in short bursts, stirring occasionally. While it’s best enjoyed fresh, reheated tartiflette is still delicious. Freezing is not recommended, as the texture of the potatoes and cheese may change.
