If you thought the classic potato gratin dauphinois couldn’t be improved, wait until you meet its brighter, lighter cousin: the 4.7/5 zucchini version that’s sweeping kitchens and turning serious gratin-lovers into courgette converts. Curious why everyone’s ditching the old school for this updated gem? Grab your apron—and your mandoline (careful with those fingers)—because things are about to get mouthwateringly good.
From French Alps to Fresh Comfort: The Gratin Dauphinois Makeover
Let’s start with a little background (because every great dish has a story, right?). Gratin dauphinois is a staple of French cooking, born in the Dauphiné area of the Auvergne-Rhône-Alpes region. Traditionally, it’s all about potatoes, cream, and sometimes a dash of milk—a recipe that defines comfort food the French way: rich, cozy, and utterly satisfying.
But times—and taste buds—have changed. Enter zucchini, the ever-so-modern and slightly sweet vegetable that brings new life (and color) to this beloved classic. The homemade zucchini gratin dauphinois keeps all the signature creamy, melt-in-your-mouth goodness, but trades some heaviness for a lighter profile that’s perfect for everyday meals and celebrations alike.
Why Zucchini? The Secret Behind the Craze
The beauty of this gratin lies in its simple fusion: thin slices of zucchini cozying up with potatoes. Zucchini brings a gentle, vegetable-forward sweetness that cuts through the richness of the cream and cheese. Not only is it a gorgeous green addition to your table—it’s a fantastic partner for meat, fish, or as a standalone centerpiece in a full vegetarian fare. Plus, you’ll love how few ingredients you need (quality over quantity, always!) and how forgiving the technique is—just focus on good products, the right slicing, and proper seasoning.
Of course, there’s a twist. While tradition says « no cheese, » this modern recipe breaks deliciously with the past, scattering grated cheese over the top for that irresistible golden crust (hey, sometimes progress tastes amazing). It’s what happens when history and cravings come together.
A touch of nutmeg and a hint of garlic (nothing overpowering—just the right perfume) elevate the flavors without stealing the show from those tender vegetables. Get them right, and your gratin will be the talk of the table.
The Zucchini Gratin Dauphinois: The Step-by-Step
Here’s what you’ll need:
- 2 medium zucchinis
- 3 large potatoes
- 3 cloves garlic
- 100g grated cheese (Emmental, Comté, or Gruyère)
- 40cl thick crème fraîche
- 15cl milk
- Butter for the dish
- Salt, freshly ground black pepper
- A pinch of nutmeg
And here’s how it all comes together:
- Preheat your oven to 180°C. Generously butter a baking dish, then rub it with a halved clove of garlic. This sneaky trick perfumes the base subtly and avoids garlic overload.
- Wash zucchini and potatoes well; no need to peel if the skins are thin and clean. Using a mandoline or sharp knife, cut them into very thin, even slices for that perfect, uniform bake.
- Cover the bottom of your dish with a layer of potato slices. Season with salt, pepper, and a bit of crushed garlic. Add a layer of zucchini. Repeat, alternating layers and seasoning each one.
- Mix crème fraîche, milk, a pinch of salt, ground pepper, and a hint of grated nutmeg until smooth. Pour this mixture over the vegetables so it soaks in evenly.
- Bake for about 50 minutes at 180°C. The top should be a lovely golden brown and the vegetables soft and yielding—test with a knife; it should slide in with no resistance.

Serving, Storing, and Other Life-Saving Tips
Storage is easy: let your gratin cool, cover with plastic film or transfer to an airtight container. It keeps well and reheats beautifully—just pop it in a 160°C oven for 15–20 minutes. A splash of cream or milk added before reheating helps keep things luscious, not dry.
Worried about zucchini watery-ness? If your zucchinis are young and finely sliced, they won’t flood your dish. For extra insurance, lightly salt and drain them before layering.
A few more helpful answers:
- You can assemble the dish several hours in advance—just bake when you’re ready.
- Cream is key for that decadent texture, but you can lighten things up by replacing part of it with milk or stock.
