Everyone needs a solid go-to party recipe. A recipe that isn’t complicated to make, but always impresses; A recipe that can be made mostly from ingredients you already have on hand, and can be prepped well in advance; A recipe that's just as good served in your home as it does when brought to someone else’s; A recipe that not only tastes amazing, but looks like it took a lot more time to prepare than it did. 

This is that recipe.

There’s no denying that shrimp cocktail is the king of all party food. There always seems to be a tray of it lurking at every holiday party, and it’s usually one of those store-bought plastic trays that tend to be quite underwhelming. The thing is though, that no matter how bad a tray of shrimp cocktail is, people still love it. But me? It’s never exactly been my favorite.

It’s not that I don’t like shrimp cocktail, I just find it to be incredibly boring. And that’s exactly why I love this recipe. It’s shrimp cocktail, only elevated. It’s much more sophisticated, lightyears more flavorful, and really doesn’t take much more effort than buying one of those trays from the grocery store.

This recipe utilizes many ingredients from the pantry, making it perfect for last minute gatherings. I always have a bag of peeled and deveined frozen shrimp in my freezer. They’re quick to defrost and quick to cook, which means you can get them on your table in minutes. Rather than boiling the shrimp for this recipe, I opt to roast them instead. It gives them so much more flavor, and while they’re hanging out in the oven, you can be working on other tasks - or better yet - hanging out with your guests. 

The other ingredients are pantry staples I think everyone should always keep on hand: mayonnaise, shallots, lemons, parsley, and a good quality mustard. The secret to this sauce is using a whole grain mustard that actually contains whole mustard seeds. The whole grain mustard gives the sauce a more mild mustardy flavor than you would get with a smooth Dijon, along with an interesting pop of texture from the mustard seeds themselves.

The roasted shrimp and whole grain mustard sauce are so much more interesting than those store-boiled shrimp served with a mixture of ketchup and horseradish. And yet because it’s still shrimp cocktail, it’s guaranteed to be a crowd pleaser.
