Step‑by‑Step Instructions for Creamy Potato and Leek Gratin
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This will ensure your Creamy Potato and Leek Gratin bakes evenly and develops that desirable golden crust. Prepare an oven-safe baking dish by lightly greasing it with butter or cooking spray, so the gratin comes out smoothly after baking.
Step 2: Prepare the Potatoes
Peel and slice the Yukon Gold potatoes thinly—about 1/8 inch thick. A mandoline slicer works beautifully here for uniformity and even cooking. Arrange the potato slices in a bowl of cold water to prevent them from browning while you prepare the other ingredients.
Step 3: Clean the Leeks
Take your leeks and cut them in half lengthwise, rinsing them thoroughly under cold water to remove any grit hiding between the layers. Slice the cleaned leeks thinly, making sure they are ready to be sautéed until tender and sweet, transforming the layers of flavor in your gratin.
Step 4: Sauté the Leeks and Garlic
In a skillet, melt a generous pat of butter over medium heat. Add the sliced leeks and sauté them for about 3-4 minutes until they become soft and translucent. Once they’re tender, stir in the minced garlic and cook for an additional minute, allowing the fragrant aroma to fill your kitchen.
Step 5: Combine Cream and Wine
Pour in the white wine and let it simmer for a couple of minutes, reducing slightly. Next, add the heavy cream, salt, and pepper to the skillet. Simmer the mixture on low heat for 3-4 minutes until it thickens slightly, creating a luscious sauce that will coat the potatoes beautifully.
Step 6: Melt the Cheese
Remove the skillet from the heat and stir in three-quarters of the grated cheese until it is fully melted and integrated into the creamy sauce. This will contribute to the rich texture of your Creamy Potato and Leek Gratin, enhancing its deliciousness in every layer.
Step 7: Layer the Gratin
Start assembling your gratin by spreading a spoonful of the creamy mixture across the bottom of the greased baking dish. Layer half of the potato slices evenly over the sauce, then pour on half of the remaining cream mixture. Repeat the layering process, finishing with a layer of potatoes and the remaining sauce on top.
Step 8: Top with Cheese and Cover
Sprinkle the remaining grated cheese generously over the top of your assembled gratin. Cover the dish tightly with aluminum foil to keep the moisture in as it bakes. This will help cook the potatoes through before browning the top.
Step 9: Bake the Gratin
Place the covered baking dish in the preheated oven and bake for 30 minutes. After this time, carefully remove the foil, returning the dish to the oven for an additional 20 minutes or until the top is golden and bubbly. Enjoy the enticing aroma that fills your kitchen!
Step 10: Cool and Serve
Once your Creamy Potato and Leek Gratin is baked to perfection, let it cool for about 5-10 minutes. This allows the layers to set slightly, making it easier to serve. Slice into portions, and savor the comforting flavors that await you and your loved ones!
Make Ahead Options
These Creamy Potato and Leek Gratin are ideal for meal prep, saving you precious time on busy weeknights! You can slice the Yukon Gold potatoes and store them in cold water in the refrigerator up to 24 hours in advance, which helps prevent browning. Similarly, after sautéing the leeks and mixing in the cream, you can assemble the gratin completely and cover it tightly with foil, refrigerating it for up to 3 days. When you’re ready to serve, simply bake it directly from the fridge, adding an extra 10-15 minutes to the baking time for a fresh, delicious result that’s just as satisfying. Enjoy the ease of having a comforting dish ready to go!

Creamy Potato and Leek Gratin Recipe FAQs
How do I select ripe, fresh leeks?
Absolutely! Look for leeks that have firm, straight stalks and crisp green tops; avoid any that are wilted or slimy. The bulbs should be white to pale green without dark spots. Fresh leeks will give your creamy potato and leek gratin that sweet, subtle flavor we love.
What’s the best way to store leftovers?
Very good question! Store your leftover creamy potato and leek gratin in an airtight container and keep it in the fridge. It will stay fresh for up to 4 days. Be sure to let it cool completely before sealing to lock in that creamy goodness!
Can I freeze creamy potato and leek gratin?
Absolutely! To freeze, portion the gratin into freezer-safe containers, leaving some space at the top as it may expand. Wrap each container tightly with plastic wrap or foil to prevent freezer burn. It can be stored for up to 3 months. Thaw in the fridge overnight before reheating in the oven for best results.
What should I do if the gratin is too watery?
If you find your gratin is too watery, there are a few steps you can take. First, check that you’re using the right type of potatoes; waxy potatoes like Yukon Gold help absorb liquid better. If it happens, try baking it a bit longer uncovered to allow excess moisture to evaporate. Alternatively, you could add a spoonful of cornstarch mixed with water to the sauce while it’s cooking to thicken it up before layering.
Are there any dietary considerations?
Definitely! This creamy potato and leek gratin contains dairy and may not be suitable for those with lactose intolerance or milk allergies. For a dairy-free alternative, try substituting heavy cream with coconut milk and using non-dairy cheese. Always double-check ingredients such as broth and cheese for any hidden allergens if you’re serving guests with dietary restrictions.
How can I ensure the leeks are grit-free?
Good question! To properly clean leeks, cut them in half lengthwise to expose the layers, then rinse them under cold running water. Allow water to wash away any grit stuck between the layers. This step is vital to ensure your creamy potato and leek gratin is smooth and delightful, without any unpleasant crunch!
