What Ingredients You Will Need

This creamy au gratin potatoes with Gruyere recipe calls for simple, wholesome ingredients that come together to deliver bold flavor and a satisfying, silky texture without any fuss. Most are pantry staples, but a few key items make all the difference.

• Russet potatoes (about 2 pounds / 900 g, peeled and thinly sliced) – Choose firm, starchy potatoes for the best texture.
• Gruyere cheese (2 cups / 200 g, shredded) – The star of the show; I recommend Emmi brand for rich, melty goodness.
• Sharp cheddar cheese (1/2 cup / 50 g, shredded) – Adds a nice tangy contrast to the Gruyere.
• Unsalted butter (3 tablespoons / 45 g, softened) – For the roux and greasing the dish.
• All-purpose flour (3 tablespoons / 24 g) – To thicken the sauce.
• Half-and-half (2 cups / 480 ml) – Adds creaminess without being too heavy.
• Heavy cream (1 cup / 240 ml) – For that silky, rich texture.
• Garlic (2 cloves, minced) – Gives a subtle, savory depth.
• Salt (1 teaspoon / adjust to taste) – Enhances all the flavors.
• Freshly ground black pepper (1/2 teaspoon) – Adds a gentle kick.
• Fresh thyme (1 teaspoon, chopped, optional) – For a lovely herbaceous note.
• Nutmeg (a pinch) – A little warmth to balance the creaminess.

Substitutions: If you need a lighter option, swap heavy cream for more half-and-half. For a gluten-free twist, use cornstarch instead of flour to thicken the sauce. And if you’re dairy-free, almond or oat milk with a dairy-free cheese alternative can work, though the flavor will shift a bit.

Equipment Needed

• Sharp mandoline slicer or chef’s knife: For uniformly thin potato slices. A mandoline makes this dangerously easy, but a steady hand with a knife works fine too.
• Medium saucepan: To make the creamy cheese sauce—non-stick is best to avoid burning the roux.
• Mixing bowls: For prepping ingredients and tossing cheese.
• 9×13-inch (23×33 cm) baking dish: Classic size for even cooking and perfect layering.
• Grater: For shredding Gruyere and cheddar—freshly grated cheese melts better.
• Wooden spoon or whisk: For stirring the sauce smoothly.
• Aluminum foil (optional): To cover the dish if the top browns too quickly during baking.

If you’re on a budget, a sharp knife and a good baking dish are the essentials. I’ve used both glass and ceramic dishes for this recipe, and both work great—just keep an eye on baking time as glass may take a bit longer.

Preparation Method

1. Preheat your oven to 350°F (175°C) and generously butter the 9×13-inch (23×33 cm) baking dish. This keeps the potatoes from sticking and adds subtle richness.
2. Peel the potatoes and slice them thinly—about 1/8 inch (3 mm) thick is ideal. A mandoline slicer helps here for uniformity. Rinse the slices under cold water to remove excess starch, then pat dry with a clean towel. This step prevents the dish from getting gluey.
3. Prepare the cheese sauce: In a medium saucepan, melt the butter over medium heat. Add minced garlic and cook for about 30 seconds until fragrant (don’t let it brown!). Stir in the flour, whisking constantly to form a smooth roux. Cook for 2 minutes to remove the raw flour taste.
4. Gradually whisk in half-and-half and heavy cream—about 2 ½ cups (600 ml) total—slowly to avoid lumps. Continue whisking until the mixture thickens and coats the back of a spoon, roughly 5-7 minutes. Stir in salt, pepper, nutmeg, and chopped thyme (if using).
5. Remove the sauce from heat and stir in the shredded Gruyere and cheddar cheeses until melted and smooth. Taste and adjust seasoning as needed.
6. Layer the potatoes in the prepared baking dish in overlapping rows. Pour a third of the cheese sauce over the first layer, gently spreading it with a spoon. Repeat layering potatoes and sauce until all are used, finishing with sauce on top.
7. Cover the dish tightly with aluminum foil and bake in the preheated oven for 45 minutes. This steams the potatoes and allows them to cook through evenly.
8. Remove the foil and bake uncovered for another 20-30 minutes until the top is golden brown and bubbly, and the potatoes are tender when pierced with a fork.
9. Let the dish rest for 10 minutes before serving—this helps the sauce thicken up and makes slicing easier.

Pro tip: If your top is browning too fast, loosely tent with foil during the last baking phase. Also, slicing potatoes too thick or unevenly can cause uneven cooking, so take your time here. The sauce should be thick enough to coat the potatoes but still pourable—think of a creamy, velvety texture.

Cooking Tips & Techniques

From my kitchen to yours, here are a few nuggets of wisdom I’ve picked up while perfecting this creamy au gratin potatoes with Gruyere recipe. First off, patience is your best friend. Don’t rush the sauce—it needs gentle heat and constant whisking to get that silky smoothness without lumps. I once tried cranking up the heat to speed things along and ended up with a grainy mess (lesson learned!).

Using freshly grated cheese is another game-changer. Pre-shredded cheese often contains anti-caking agents that can affect melting. Also, layering is more than just stacking potatoes—it’s about spreading the sauce evenly so every bite gets that comforting creaminess.

When baking, covering the dish initially traps moisture so the potatoes cook fully without drying out. Then, removing the foil allows the top to crisp up and brown beautifully. If you forget this step, your dish might be creamy but lack that signature crunchy topping.

Lastly, remember to let the gratin rest after baking. I know it’s tempting to dig right in, but the sauce sets as it cools, making serving easier and flavors more melded. Multitasking tip: prep your potatoes and sauce ahead in the morning, refrigerate, then bake right before dinner—perfect for busy days!

Variations & Adaptations

While this creamy au gratin potatoes with Gruyere shines as is, you can tweak it to fit your mood, diet, or what’s in your fridge. Here are some ideas I’ve tried and loved:

• Vegetable boost: Add thinly sliced caramelized onions or sautéed mushrooms between layers for an earthy twist.
• Herb swap: Replace thyme with rosemary or sage for a different aromatic profile—both work beautifully with the cheese.
• Gluten-free version: Use cornstarch or a gluten-free flour blend instead of all-purpose flour in the sauce.
• Cheese variations: Swap Gruyere for fontina or mozzarella if you want a milder, creamier melt, or add a bit of Parmesan on top for extra crispiness.
• Dairy-free adaptation: Use unsweetened almond or oat milk with a dairy-free cheese alternative; though it’s not quite the same, it still satisfies that creamy craving.

One personal favorite is adding a sprinkle of smoked paprika on top before baking—it adds a subtle smoky kick that pairs surprisingly well with the creamy potatoes and Gruyere.

Serving & Storage Suggestions

This creamy au gratin potatoes with Gruyere is best served warm out of the oven when the cheese is still gooey and the top is golden and crisp. I like to pair it with roasted chicken or a simple green salad to balance the richness. For drinks, a crisp white wine like Sauvignon Blanc or even a cold beer complements the dish nicely.

If you have leftovers (which is rare, but it happens), store them covered in the refrigerator for up to 3 days. To reheat, warm in a 350°F (175°C) oven for 15-20 minutes until heated through and bubbly again. Microwaving works too, but you might lose that lovely crispy top. Fun fact: the flavors deepen after a day or two, so leftovers can be even tastier!

Nutritional Information & Benefits

Each serving of this creamy au gratin potatoes with Gruyere packs roughly 350-400 calories, depending on portion size. It’s a rich source of protein and calcium from the cheeses, plus potassium and vitamin C from the potatoes. While it’s admittedly indulgent, using half-and-half alongside heavy cream lightens the fat content a bit compared to recipes relying solely on heavy cream.

If you’re watching carbs, remember potatoes are a starchy vegetable providing energy and fiber, so this dish fits well into balanced eating when enjoyed in moderation. For those with dairy allergies, swapping to plant-based alternatives is doable but changes texture and flavor. Overall, this dish is a satisfying way to enjoy comfort food with a touch of wholesome goodness.

Conclusion
