Why We Love This Cheesy, Creamy Delight
There’s something magical about the combination of tender potatoes, sweet fennel, and creamy, melted Gruyère cheese. This dish is comfort food with a gourmet twist—perfect for cozy dinners or holiday gatherings. We first made this gratin during a family celebration, and it instantly became the star of the table. The aroma alone is enough to make you swoon, but the first bite? Pure bliss.
🧀 What Makes Gruyère Cheese Special?
Gruyère is the ultimate melting cheese, with a nutty, slightly salty flavor. It’s the perfect choice to elevate a humble gratin into something truly luxurious.
The Story Behind This Recipe
We discovered this recipe while trying to incorporate more fennel into our meals. Fennel has a subtle anise-like flavor that pairs beautifully with creamy potatoes and rich cheese. Initially, we were hesitant—would the fennel be too overpowering? Spoiler alert: it wasn’t! Instead, it adds a delicate sweetness that balances the richness of the dish.
This gratin has become a family favorite, gracing our table at everything from weeknight dinners to special occasions. It’s fancy enough to impress guests but easy enough to whip up any time you’re craving something indulgent.
🌱 Can I Make This Vegetarian?
Good news—it already is! Just make sure your Gruyère cheese is made with vegetarian rennet.
A Side Dish That Steals the Show
Most side dishes are content to hang out in the background, quietly complementing the main course. Not this one. Our fennel and potato gratin has a habit of outshining everything else on the plate. The creamy layers, golden crust, and fragrant herbs make it irresistible.
We’ve served it alongside roast vegetables, vegetarian meatloaf, and even as a standalone meal with a fresh green salad. It’s versatile, crowd-pleasing, and always gets rave reviews.
🥔 Pro Tip: Choose the Right Potatoes
Yukon Gold or other waxy potatoes are ideal for gratins. They hold their shape beautifully and soak up the creamy sauce without turning mushy.
How We Perfected the Recipe
Creating the perfect gratin is all about balance. Too much sauce, and it can feel heavy; too little, and it’s dry. After a bit of trial and error, we’ve nailed the ideal ratio of cream to cheese to potatoes. The result? A dish that’s indulgent without being overwhelming.
We also experimented with the fennel—sautéing it lightly before layering it into the gratin enhances its natural sweetness and ensures it’s tender by the time the dish is done.
💡 Fun Fact: Gratin Origins
The word “gratin” comes from the French verb “gratter,” meaning “to scrape.” It refers to the crispy, golden crust formed by cheese or breadcrumbs baked on top.
Why You’ll Love It Too
This gratin isn’t just delicious—it’s also a joy to make. There’s something so satisfying about layering the potatoes and fennel, pouring over the creamy sauce, and watching the Gruyère melt into a bubbly, golden topping.
It’s the kind of recipe that feels like an act of love, whether you’re making it for family, friends, or just yourself.

Ingredients
- 2 large fennel bulbs thinly sliced (fronds reserved for garnish)
- 4 large potatoes thinly sliced
- 2 cups Gruyère cheese grated
- 2 cups heavy cream
- 2 cloves garlic minced
- 1 tbsp butter for greasing the dish
- 1 tsp fresh thyme leaves or 1/2 teaspoon dried thyme
- Salt and pepper to taste
Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C). Grease a baking dish with butter.
- Prepare Fennel and Potatoes: Thinly slice the fennel bulbs and potatoes. A mandoline slicer works well for uniform slices.
- Layer the Vegetables: Arrange a layer of potato slices in the bottom of the greased baking dish. Top with a layer of fennel slices. Season with a bit of salt, pepper, and thyme. Sprinkle a portion of the minced garlic and a handful of grated Gruyère cheese over the layer. Repeat layering until all the ingredients are used, finishing with a layer of cheese on top.
- Add Cream: Pour the heavy cream evenly over the layered vegetables and cheese.
- Bake: Cover the dish with foil and bake in the preheated oven for 45 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the top is golden and the vegetables are tender.
- Garnish and Serve: Let the gratin cool slightly before serving. Garnish with reserved fennel fronds for a touch of color and flavor.
Notes
Frequently Asked Questions About Fennel and Potato Gratin with Gruyère Cheese
🥔 Can I Use a Different Cheese Instead of Gruyère?
Absolutely! If you don’t have Gruyère, you can substitute it with Swiss, Parmesan, or even sharp cheddar. 🧀 Each will bring its own unique flavor, but Gruyère’s nutty creaminess is classic for this dish.
🕒 How Far Ahead Can I Make This Dish?
You can assemble the gratin up to a day ahead and store it in the fridge, unbaked, covered with foil. When ready, bake it fresh for best results. 🍽️ Reheating leftovers also works beautifully!
🥛 Can I Use a Milk Substitute?
Of course! Half-and-half or cream works best for richness, but you can use unsweetened almond, oat, or soy milk if you want a lighter version. Just note the sauce may be slightly less creamy. 🥥
🔥 What’s the Best Way to Get a Crispy Top?
For a golden, bubbly finish, broil the gratin for 2–3 minutes after baking. Just keep an eye on it to avoid burning! 🔥 Pro tip: Sprinkle a bit of extra Gruyère on top before broiling.
📏 What’s the Best Dish Size for This Recipe?
An 8×8 or 9×9-inch baking dish works perfectly for even cooking and a nicely layered presentation. 📐 For a crowd, double the recipe and use a 9×13-inch pan.
