Ingredients

Instructions

Step 1: Preheat the Oven

Begin by setting your oven to 400°F (200°C). Ensuring the oven is fully preheated is crucial for even cooking and achieving the perfect golden crust. Use an oven thermometer if necessary to verify temperature accuracy. Prepare your baking dish during this time by lightly greasing it with butter or non-stick spray to prevent sticking and facilitate easy serving later.

Step 2: Prepare the Potatoes

Choose high-starch potatoes like Yukon Gold or a waxy variety for their creaminess and ability to hold shape. Peel the potatoes meticulously using a sharp vegetable peeler or paring knife, removing all skin to ensure smooth layers. Rinse the peeled potatoes under cold running water to wash away excess surface starch, which can cause the gratin to become gluey. Pat the slices dry thoroughly with a clean kitchen towel or paper towels to prevent excess moisture from interfering with layering and baking.

Using a mandoline slicer is highly recommended for achieving uniformly thin slices (approximately 1/8 inch thick). Consistent thickness ensures even baking and a harmonious texture throughout the dish. If you don’t have a mandoline, carefully slice with a sharp knife, maintaining even thickness, and take your time to avoid uneven layers or tearing.

Step 3: Prepare the Leeks

Leeks are notorious for trapping dirt within their layers, so thorough cleaning is essential. Trim the dark green tops and the root end, setting aside only the white and light green portions. Slice the leeks lengthwise first, then slice crosswise into thin strips. Rinse the slices in a bowl of cold water, agitating gently to dislodge any grit. Drain thoroughly in a colander and pat dry with a clean towel.

Step 4: Prepare the Bacon

Cut the streaky bacon into strips or small cubes. Heat a frying pan over medium heat and cook the bacon until crispy, approximately 6-8 minutes, stirring occasionally. Once crisp, remove with a slotted spoon or tongs and drain on paper towels. Save the rendered bacon fat—this will be used to fry the sage leaves and enrich the flavor of the gratin. Set aside the cooked bacon for layering.

Step 5: Fry the Sage Leaves

In the remaining bacon fat, briefly fry the fresh sage leaves until they turn crispy and fragrant, about 30 seconds to 1 minute. Use tongs or a slotted spoon to remove the sage, draining excess oil on paper towels. The crispy sage adds a fragrant, earthy note that elevates the dish. Scatter the leaves over the assembled layers at the appropriate step.

Step 6: Assemble the Layers

Grease the gratin dish thoroughly with softened butter, ensuring every corner is coated to prevent sticking. Begin layering: spread half of the potato slices evenly across the bottom of the dish, overlapping slightly to form a uniform layer. Follow with the sliced leeks, distributing them evenly over the potatoes. Sprinkle the crispy bacon strips over the leeks, ensuring they are evenly spread to maximize flavor in every bite. Carefully scatter the fried sage leaves over the bacon and leeks, preserving their crispness.

Next, grate the hard cheese directly over the layered ingredients, covering the entire surface. The cheese will melt during baking, creating a luscious, cheesy crust and binding the layers together. Place the remaining potato slices on top, overlapping as necessary to form the final layer.

Step 7: Pour the Stock

Heat the stock in a small saucepan until warm or simmering. Pour the warm stock evenly over the layered potatoes, ensuring it reaches the base of the dish without submerging the top layer entirely. The stock will keep the dish moist and contribute to the creamy texture as it bakes, infusing flavor into the potatoes.

Step 8: Season and Dot with Butter

Season the entire dish generously with sea salt and freshly ground black pepper, adjusting to taste. Dot the surface with small pieces of the remaining butter, distributing evenly. This butter will melt during baking, adding richness and helping develop a golden, crispy crust.

Step 9: Cover and Bake

To prevent the top from browning too quickly, cover the gratin with a sheet of waxed paper or aluminum foil, buttered side down if using waxed paper. Place the covered dish in the preheated oven and bake for approximately 45 minutes. This initial baking step softens the potatoes and melds the flavors together.

Step 10: Check for Doneness

After 45 minutes, carefully remove the covering and check the potatoes’ tenderness by inserting a skewer or sharp knife into the center. They should be nearly cooked through but still holding their shape. If necessary, bake for an additional 5-10 minutes until the potatoes are tender and the edges are starting to turn golden.

Step 11: Prepare and Pour the Sauce

While the gratin is baking, prepare the mustard-infused creme fraiche sauce. In a small bowl, combine the mustard seeds with the creme fraiche, stirring gently to incorporate the seeds evenly. The mustard seeds will add a subtle crunch and burst of flavor, contrasting beautifully with the creamy base.

Once the initial baking is complete and the potatoes are nearly done, remove the dish from the oven. Spread the creme fraiche mixture evenly over the top using a rubber spatula, smoothing it out to create a uniform layer. This addition introduces a tangy, spicy element that complements the richness of the cheese and bacon.

Step 12: Final Baking

Return the gratin to the oven, uncovered, and bake for an additional 15 minutes. During this time, the creme fraiche layer will heat through, bubble, and develop a slightly browned, crispy surface. The cheese will be fully melted and bubbling, and the top will be beautifully golden. Keep an eye on the dish to prevent over-browning, particularly towards the edges.

Step 13: Serve Hot

Remove the gratin from the oven and allow it to rest for a few minutes before serving. This resting period helps the layers set slightly, making portions easier to serve. Use a sharp knife or spatula to carefully portion the gratin onto plates. Serve immediately while it’s hot, enjoying the rich, creamy, cheesy layers complemented by the smoky bacon and fragrant sage.

Preparation Tips

• Uniform Slices: Consistency in potato thickness ensures even cooking. Mandoline slicers are invaluable for precision.
• Layering: Overlapping slices slightly creates a cohesive dish with evenly distributed flavors and textures.
• Bacon and Sage: Fry bacon and sage separately to maximize flavor and crispness before adding to layers.
• Stock Usage: Use warm stock to prevent disrupting the layers when pouring over the potatoes.
• Cheese Selection: Choose a high-quality, melting cheese like Gruyère for authentic flavor and texture.
• Resting Time: Allow the gratin to sit a few minutes post-baking for cleaner slices and better presentation.

Save and Store

Leftover gratin can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, cover with foil and warm in a 350°F (175°C) oven until heated through, about 15-20 minutes. For best results, reheat gently to preserve the creamy texture. To freeze, wrap tightly in plastic wrap and foil, storing for up to 2 months. Thaw overnight in the refrigerator and reheat as described.

Frequently Asked Questions (FAQ)

Can I make this gratin ahead of time?

Yes, assembling the gratin a day in advance and refrigerating it allows the flavors to meld. Bake directly from refrigeration, adding an extra 10-15 minutes to the baking time if cold.

Can I omit the bacon for a vegetarian version?

Absolutely. You can replace bacon with smoked mushrooms, sun-dried tomatoes, or omit entirely for a vegetarian but still flavorful dish.

What cheese works best for this gratin?

Gruyère, Comté, or Emmental are excellent choices due to their melting qualities and rich flavor. Feel free to mix cheeses for depth.

Is creme fraiche essential?

It contributes to the creamy texture and tangy flavor. You can substitute with sour cream or Greek yogurt, but the taste and texture will differ slightly.

How do I prevent the gratin from becoming too greasy?

Use lean bacon and drain excess fat thoroughly. Also, do not overload with butter or cheese. Baking uncovered helps excess moisture evaporate, resulting in a crispier top.
