Corned Beef Tacos with Guinness Caramelized Onions
For the tacos, the tender, slow-cooked meat is piled onto flour tortillas and topped with Guinness caramelized onions, shredded Swiss cheese and shredded cabbage.
Heat a medium sauté pan over medium heat, add the oil and heat through. Add the butter and allow to melt then add the onions to the pan and stir to coat. Sauté the onions until they are soft and tender, about 10 minutes, then sprinkle with the sugar, stirring to combine.
Cover and continue to cook the onions, checking about every 5 to 10 minutes, stirring occasionally, until the onions are dark in color and caramelized, about 30 minutes. The exact time may vary depending on the onions. Add the Guinness to deglaze the pan and simmer until all the liquid has been absorbed, about an additional 5 minutes. Remove from heat and set aside.
For the creamy slaw:
In a medium mixing bowl whisk together the mayonnaise, sour cream and apple cider vinegar.
Add the cabbage and carrots, tossing to combine and evenly coat in the mixture.
To assemble the tacos:
Heat a large cast iron pan over medium heat. Add about ¼ of cheese to the pan in a circle no larger than the tortilla. Add 1 tortilla over the cheese and cook until the cheese is crispy, about 1 minute. Use a metal spatula to lift the cheesy tortilla to a platter or plate. Repeat the process with the remaining tortillas and cheese.
Top each top with a scoop of the corned beef, caramelized onions and the slaw mixture. Serve immediately.
