These oven baked oysters are topped with buttery shallots, white wine, crème fraîche, Parmesan and breadcrumbs, then baked until bubbling and golden. Rich, elegant and surprisingly easy, they may even convert oyster skeptics!
Some foods try to win you over. Oysters simply sit there on a bed of ice, cold and slippery, and expect you to be impressed.
Very French, when you think about it.
If you have never understood the enthusiasm, I cannot entirely blame you.
But these oven baked oysters are an entirely different experience. Once cooked, the oysters become tender and firmer, that slippery raw texture disappears, and each one is covered with buttery shallots, white wine and crème fraîche before being finished with Parmesan and breadcrumbs.
The result is creamy underneath, golden and lightly crisp on top, and almost unfairly delicious. I cannot legally guarantee that this recipe will convert every oyster skeptic, but I very much like my chances.

The Oyster Recipe for People Who Don't Like Oysters
To be clear, I adore raw oysters. Have you ever been lucky enough to taste oysters from Brittany (Bretagne), in France? They are the absolute best in the world, in my spectacularly unbiased French opinion.
For years, I thought cooking a beautiful oyster was practically disrespectful. Then, at a tiny wooden seafood shack in Malibu, I tasted my first cooked oyster. It was breaded, fried and served with fries.
When I later told my French family, they reacted as though California had personally vandalized a national monument. The oyster purists were horrified.
Unfortunately for them, I had loved every crisp, juicy, scandalous bite.
These oysters au gratin are rather more elegant, but they have the same power to change someone's mind. Cooking transforms the texture, while the rich white wine and shallot sauce softens the strong briny flavor. Add crème fraîche, Parmesan and a golden breadcrumb topping, and suddenly the person who "doesn't eat oysters" is reaching for another one.
Why You'll Love These Oysters au Gratin
- Perfect for oyster beginners: Cooking gives the oysters a firmer, more tender texture.
- Creamy and crisp: The crème fraîche creates a rich sauce while the Parmesan and breadcrumbs turn beautifully golden.
- Easy but impressive: They look wonderfully elegant but require only a few simple steps.
- Ideal for entertaining: Serve them for Christmas, New Year's Eve, Valentine's Day or a French-inspired dinner party.
- Ready in 35 minutes: Fancy little oysters, remarkably little drama.
Ingredients You'll Need
- Oysters: Choose 12 fresh medium-large cupped oysters with deep bottom shells. In France, I prefer size No. 2 oysters because they are plump enough to stand up to the sauce.
- Dry white wine: Use a dry white wine that you would happily drink. Muscadet, Sauvignon Blanc or Pinot Grigio will all work well.
- Crème fraîche: This thick cultured cream makes the topping especially rich and silky. It is now fairly easy to find in larger U.S. supermarkets, often near the specialty cheeses or cultured dairy products rather than beside the regular cream. If you cannot find it, full-fat sour cream is the best substitute, although it will taste slightly tangier.
- Shallot and salted butter: They form the savory base of the sauce. Let the wine reduce for a few minutes so the topping tastes concentrated rather than watery.
- Parmesan and breadcrumbs: Together, they create the golden gratiné finish. Plain dry breadcrumbs or panko both work.
- Black pepper: The oysters, salted butter and Parmesan already provide plenty of salt, so pepper is generally all you need.
What Can I Substitute for Crème Fraîche?
Full-fat sour cream is the easiest substitute and can be used in the same amount. It is a little tangier and may not melt quite as silkily as crème fraîche, but it works well here because each oyster receives only a small spoonful and the baking time is short. Avoid light or fat-free sour cream.
I do not recommend replacing the crème fraîche directly with liquid heavy whipping cream. Unless you reduce it first, it is too thin and may leave you with oyster soup, which sounds considerably less glamorous than oysters au gratin.
How to Make Oven Baked Oysters
1. Prepare and drain the oysters
Shuck the oysters, remove the top shells and discard the first liquid. Leave the oysters in the deeper bottom shells. They will release more liquid while you prepare the sauce, so drain them once again immediately before adding the toppings.
Arrange the shells in a baking dish.
2. Make the shallot and white wine mixture
Melt the salted butter in a small saucepan. Add the finely chopped shallot and cook gently until it begins to soften.
Pour in the white wine and let everything simmer for a few minutes, until the wine has reduced and the mixture looks glossy.
3. Top the oysters
Spoon the buttery shallot mixture evenly over the drained oysters. Add one generous teaspoon of crème fraîche to each shell, then sprinkle with breadcrumbs, Parmesan and black pepper.
4. Bake until bubbling and golden
Bake the oysters at 350°F (180°C) for approximately 12 to 15 minutes, until the oysters are cooked and the topping is bubbling.
If they need more color, switch the oven to broil for the final minute or two. Watch them closely: Parmesan under a broiler can go from pale to Parisian café brown to charcoal with impressive efficiency.
Serve immediately while the sauce is hot and the topping is still golden.
What to Serve with Baked Oysters
Serve these baked oysters in the shell with a fresh baguette to catch any sauce left behind. A crisp dry white wine, Muscadet or Champagne pairs beautifully with them.
If everyone at your table already belongs to the oyster fan club, try my Baked Oysters with Champagne next. That recipe is more delicate and festive, with a buttery Champagne sauce and no cheese; this Parmesan version is richer, crunchier and especially good for winning over reluctant oyster eaters.

Oven Baked Oysters with Parmesan (Oysters au Gratin)
Ingredients
- 12 fresh medium-large cupped oysters in their shells (preferably No. 2 or similarly plump oysters)
- 60 g salted butter 4 tablespoon + 1 tsp
- 50 ml dry white wine 3 tablespoon +1 tsp
- 60 ml crème fraîche (¼ cup) full-fat sour cream can be substituted
- 1 shallot finely chopped
- Finely grated Parmesan (as needed, approximately ¼ cup)
- Plain dry breadcrumbs or panko (as needed, approximately ¼ cup)
- Freshly ground black pepper to taste
Instructions
- Preheat the oven to 350°F (180°C), with a rack positioned in the upper third of the oven.
- Shuck the oysters and discard the first liquid from the shells. Remove the top shells, leaving each oyster in its deeper bottom shell. Set them aside while preparing the sauce, then drain any additional liquid they release before adding the toppings.
- Melt the salted butter in a small saucepan over medium-low heat. Add the finely chopped shallot and cook gently for 2 to 3 minutes, without browning.
- Add the white wine and simmer for another 3 to 5 minutes, until the wine has reduced and the shallot mixture looks glossy. Remove from the heat.
- Arrange the oyster shells in a baking dish. Spoon the shallot and white wine mixture evenly over the oysters.
- Top each oyster with one generous teaspoon of crème fraîche. Sprinkle evenly with the breadcrumbs and Parmesan, then finish with freshly ground black pepper.
- Bake for 12 to 15 minutes, until the oysters are cooked and the topping is hot and bubbling. If needed, broil for 1 to 2 minutes at the end, just until beautifully golden. Watch closely to prevent burning.
- Serve immediately while hot.
Notes
* Drain the oysters a second time immediately before topping them; this prevents the finished sauce from becoming watery.
* Because the oysters, salted butter and Parmesan are naturally salty, additional salt is usually unnecessary.
