Before you start

Before beginning, ensure your potatoes are peeled and sliced into even, quarter-inch thick rounds to guarantee uniform cooking. Have your bacon lardons ready and ensure the Reblochon cheese is at room temperature for about thirty minutes before placing it in the slow cooker, as this helps it begin to melt more efficiently as the temperature rises.

Clear a space on your countertop for the slow cooker and ensure it is plugged into a safe, grounded outlet away from any water sources.

Ingredients at a glance (4)
  • 8 oz smoked bacon lardons
  • 1.5 lb potatoes, peeled and sliced
  • 1/2 tsp black pepper
  • 1 whole Reblochon cheese, halved horizontally

Instructions

Phase 1: Layering the Ingredients

  1. Layering the base
    Place the smoked bacon lardons into the bottom of the slow cooker to ensure they render their fat as the dish cooks. Layer the sliced potatoes evenly over the bacon to provide a sturdy foundation for the cheese.
    Look for The bacon should be spread in an even layer at the bottom of the slow cooker insert.
    Tip Ensure the potato slices are of uniform thickness so they cook through consistently during the long, slow heating process.

At the end of this phase, the ingredients should be neatly layered within the slow cooker. The bacon lardons should form a base layer to render fat, and the potatoes should be distributed evenly to ensure they cook through.

Check that the potatoes are sliced consistently and that all ingredients are organized for easy assembly before turning on the device.

Phase 2: Seasoning and Cheese Placement

  1. Seasoning and adding cheese
    Sprinkle the potatoes with black pepper. Place the two halves of the Reblochon cheese on top of the potatoes with the rind facing upward to allow the creamy center to melt down slowly into the potatoes.
    Look for The cheese should sit securely on top of the potato layer.
    Tip Do not over-season with salt, as the bacon lardons provide a significant amount of saltiness to the final dish.

The black pepper should be evenly distributed over the potato layer. The Reblochon cheese halves should be positioned rind-up on the surface, ensuring they are stable. Everything should look ready for the slow, steady heat, with the cheese positioned to melt perfectly into the layers below as the cooking cycle begins.

Phase 3: Slow Cooking

  1. Slow cooking
    Cover the slow cooker and cook on low for 4 hours until the potatoes are tender and the cheese is fully melted and golden. Check that the bacon has reached an internal temperature of at least 160°F (71°C) to ensure it is thoroughly cooked.
    Look for The potatoes should be fork-tender and the cheese should be bubbling and melted through the layers.
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip Avoid lifting the lid too often, as this releases the heat and steam necessary to cook the potatoes evenly.

The final phase concludes when the potatoes are fork-tender and the cheese has achieved a beautiful, golden, and melted consistency. The kitchen should smell savory and earthy. Ensure the bacon has reached 160°F (71°C) throughout the dish. Once these visual and temperature cues are met, the dish is ready for immediate serving.

Common mistakes

A common mistake is slicing the potatoes too thick, which prevents them from cooking through in the allotted time. Another error is using a cheese that does not melt well; ensure you use a high-fat, soft-rind cheese.

Avoid opening the lid frequently during the cooking process, as this releases vital steam and heat, which can cause the potatoes to cook unevenly and prolong the process significantly. Finally, do not over-salt, as the bacon is quite salty.

How to tell it’s done

The tartiflette is done when the potatoes are completely tender and can be easily pierced with a fork with no resistance. The Reblochon cheese should be entirely melted, forming a thick, bubbly, and golden-brown layer across the top.

The internal temperature of the bacon lardons must reach at least 160°F (71°C) to ensure food safety. If the potatoes are still firm, continue cooking for an additional thirty minutes before serving.

  • Ground meat: 160°F (71°C) in the thickest part
