Ingredients

Instructions

1. Preheat and Prepare the Baking Dish

Begin by setting your oven to 400°F (200°C). While the oven heats, generously butter a 13x9x2-inch glass baking dish. Use a pastry brush or a paper towel to ensure even coating. Proper greasing prevents sticking and adds a subtle richness to the crust. Place the dish on a stable surface near your prep station for easy assembly.

2. Prepare and Slice the Potatoes

Peel the russet potatoes thoroughly with a sharp vegetable peeler, removing any eyes or blemishes. For uniform slices, employ a mandoline slicer set to approximately 1/8-inch thickness. If using a food processor, attach the slicing disc and feed the peeled potatoes through the feeder. If slicing by hand, carefully cut the potatoes with a sharp knife, maintaining as consistent a thickness as possible to ensure even cooking. Overlapping slices slightly in the dish creates a dense, cohesive gratin.

3. Layer the Potatoes with Seasoning and Creme Fraiche

Arrange half of the potato slices in the prepared baking dish, forming an overlapping pattern that covers the entire bottom. Lightly season this layer with salt and pepper to enhance flavor. Using a spatula or offset spatula, spread a portion of creme fraiche evenly over the layer, smoothing it to coat each slice. The creme fraiche adds creaminess and tang, balancing the richness of the cheese.

4. Add the First Layer of Cheese

Sprinkle approximately half of the shredded Gruyere cheese over the creme fraiche. Distribute evenly to ensure a consistent cheesy layer that will melt into the potatoes, creating a luscious texture. Gruyere cheese is renowned for its nutty, slightly sweet flavor and excellent melting qualities, making it a perfect choice for gratins.

5. Layer the Remaining Potatoes

Place the second half of the potato slices over the cheese layer, overlapping them slightly for full coverage. Season again with salt and pepper. Spread the remaining creme fraiche over this layer, ensuring even distribution. Finish by sprinkling the remaining Gruyere cheese over the top, creating a golden, bubbly crust upon baking.

6. Bake the Gratin

Place the assembled dish on the center rack of the preheated oven. Bake uncovered at 400°F (200°C) for 30 minutes. This initial high heat helps develop a golden crust. After 30 minutes, reduce the oven temperature to 350°F (175°C) and continue baking for an additional 45 minutes. During this period, the potatoes will become tender, and the cheese will melt and brown, forming a crisp topping. Check for doneness by inserting a fork or skewer; the potatoes should be soft and easily pierced.

7. Rest and Set the Dish

Once baked to perfection, remove the gratin from the oven and allow it to rest for 10 to 15 minutes. Resting helps the layers set, making it easier to cut and serve without the dish falling apart. Use a sharp knife to portion the gratin cleanly, revealing the beautifully layered interior.

8. Garnish and Serve

Just before serving, sprinkle freshly chopped Italian parsley and finely sliced scallions over the top for a vibrant color contrast and fresh flavor. Serve hot, ideally alongside roasted meats, grilled vegetables, or a crisp green salad for a well-rounded meal.

Preparation Tips

• Uniform slices are crucial: To ensure even cooking, slices must be consistent in thickness. A mandoline slicer or food processor makes this task straightforward and precise.
• Cheese quality matters: Opt for high-quality Gruyere, such as Boar’s Head, for superior flavor and melting properties. Cheaper options can be greasy or rubbery, diminishing the dish’s overall quality.
• Layering technique: Slight overlaps in potato slices create a dense, satisfying texture. Avoid gaps for a cohesive gratin.
• Seasoning: Generous salt and black pepper between layers enhance depth of flavor. Consider adding a pinch of nutmeg or garlic powder for additional complexity.
• Crust browning: If the top isn’t browning enough, increase oven temperature slightly or broil for 1-2 minutes, watching carefully to prevent burning.

Nutritional Information

Tips and Tricks

• Use a high-quality cheese: The flavor and melting qualities significantly influence the final dish. Seek out aged Gruyere for depth of flavor.
• Pre-slice potatoes: Using a mandoline or food processor saves time and ensures uniform slices, which is essential for even cooking and presentation.
• Layer strategically: Overlapping slices and seasoning each layer enhances flavor and texture.
• Control browning: Keep an eye during the final baking stages; broiling briefly can give a perfect crust if needed.
• Rest before serving: Patience allows the gratin to set, making portions neater and easier to serve.

Add-ons and Variations

• Herbs: Incorporate thyme, rosemary, or chives into the layers for extra aroma.
• Garlic: Rub the baking dish with garlic or add minced garlic between layers for a flavor boost.
• Vegetables: Add thinly sliced leeks, shallots, or mushrooms for additional complexity.
• Spicy kick: Sprinkle red pepper flakes or add a dash of cayenne pepper for heat.

Side Dishes

• Roasted Brussels sprouts
• Green bean almondine
• Mixed greens with vinaigrette
• Carrot and fennel salad
• Garlic sautéed green beans

Improvements and Variations

• Vegan version: Replace creme fraiche with coconut or cashew-based cream and use vegan cheese. Adjust seasoning accordingly.
• Gluten-free: Naturally gluten-free, but ensure no gluten-containing additives if using pre-shredded cheese with anti-caking agents.
• Additional layers: Incorporate sautéed onions or bacon bits for a savory twist.

Save and Store

Leftover gratin can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place slices in a preheated oven at 350°F (175°C) for about 15 minutes or until warmed through. For best results, reheat uncovered to maintain the crispy top. You can also freeze individual portions, but note that texture may change slightly upon thawing and reheating.

FAQ

Can I prepare this dish ahead of time?

Yes. Assemble the gratin up to a day in advance, cover tightly with plastic wrap, and refrigerate. Remove from fridge 30 minutes before baking to allow even cooking. Add a few extra minutes to cooking time if chilled.

Can I use other types of cheese?

While Gruyere provides a distinctive nutty flavor, you can experiment with Comté, Emmental, or a blend of Swiss cheeses. However, the flavor profile will shift accordingly.

Is it possible to make this dish dairy-free?

Yes, with substitutions such as coconut cream or cashew-based sauces and dairy-free cheese options. The texture may differ slightly but can still be delicious.

How do I prevent the top from burning?

Monitor during the last few minutes, and if the top browns too quickly, lightly cover with aluminum foil. Using a lower oven temperature for the final stage also helps.
