Delicious Recipes for St. Patrick's Day

St. Patrick's Day isn't just about what you wear, it's also about what you share. While modern celebrations often focus on drinks, we love highlighting the food traditions that bring everyone together. From classic comfort dishes to updated, dietary-friendly options, these recipes help round out your celebration and make hosting easy and inclusive.

Traditional St. Patrick's Day Recipes

Contrary to modern notions, corned beef and cabbage is not actually a“traditional” Irish recipe. Corned beef was first discovered by Irish-American immigrants in New York’s Jewish delis. The inexpensive and salty meat paired with cabbage was a tasty and thrifty alternative to the more traditional Irish meals of pork and potatoes. More of a modern tradition, it's still a tasty way to celebrate St. Patrick's Day! On the other hand, colcannon is a delicious Irish dish made with foods found in a typical country garden: potatoes, cabbage or kale, and milk. Modern variation include scallions, leaks, and onions or chives (shh, we've also added bacon to our recipe!). And, let's not forget about everyone's favorite—Irish soda bread! Better known as wheaten bread in Ireland, this quick bread became a staple because it uses very few, and extremely affordable ingredients.

Yummy St. Patrick's Day Treats

Guinness chocolate cake has become a modern tradition that many people delight in participating in. What could be a more delicious flavor combination than rich chocolate and the deep, earthiness of an Irish stout, topped off with a buttercream frosting infused with Bailey’s caramel liqueur? Adding the Guinness makes for a deliciously moist and dark chocolate cake.
