Garnish your fresh oysters with this Mediterranean Oyster sauce with Sumac! It's a unique Lebanese spin on the classic mignonette that pairs beautifully with raw oysters.
Sumac is a common ingredient in Lebanon that's used to add a briny flavor to dishes and adding in oysters has been one of my favorite sumac recipes!

Living in the great Pacific Northwest, oysters are a common appetizer in our household. Whether we grab some from neighbors, get our own from the bay, or purchase from a local oyster farm, we make sure to keep them in our roation all year-around.

Mediterranean Sauce for Oysters
Raw oyster toppings, such as mignonette, are typically made using a tasty vinegars and few ingredients.
And whether you're dishing up fresh raw oysters on the half-shell, or baked oysters - this oyster vinaigrette will be the star of the show. Without using onions or shallots, you can get a strong flavor - that typically pairs great with oysters, with a spice called Sumac, along with red wine vinegar - it's sidekick for this recipe.
Sumac is the secret spice to make this vinaigrette sauce for oysters extra special. It has a purple color to it, which gives this vinaigrette it's unique color. It's a Mediterranean spice that is commonly used in various Middle eastern dishes, however, if you'd like to substitute it for another common ingredient, I do share a substitute option!
INGREDIENTS NOTES
- Red wine vinegar. Being that this is a staple ingredient, make sure your red wine vinegar is fresh to make the best oyster vinaigrette recipe. Using red wine vinegar and sumac (talked about below) eliminates the need to use shallots, making this a great mignonette recipe without shallots - which can be hard to come by when going the traditional route.
- Extra virgin olive oil. I like using a little fat in this mignonette. If you don't have olive oil on hand and prefer not to purchase some, substitute for butter. However, to get an authentic Mediterranean style vinaigrette, it's best to use a good extra virgin olive oil.
- Sumac. This is a highly used spice in Mediterranean cuisine. Traditionally used for vinaigrettes in one of our popular salads. I also used it in this Fried Feta Spinach Salad. It's citrusy but with a deeper flavor profile. If you can't get it in your hands and this Amazon Sumac option is not going to work in your time frame, than you can try substituting 1 teaspoon of sumac for ½ teaspoon of fresh lemon zest. Though it won't be exactly the same, you will get a citrusy flavor substitute without added liquid.
- Garlic. Freshly minced garlic is best, I wouldn't use pre-minced garlic that's typically sold in a jar.
- Sprinkle of salt if you choose to would be fine.
- Fresh Parsley. For oyster garnish chop fresh flat-leaf parsley. Parsley is also a widely used herb in Mediterranean cuisine, especially on seafood, salads, and well just about any dish.
