Steps to Make Pastrami and Irish Cheddar Mac & Cheese
- Preheat the oven to 375°F. Bring a large pot of water to a boil and add 1 ½ teaspoons of Kosher salt.
- Add the elbow macaroni and cook according to package directions for al dente minus two minutes. Drain the macaroni in a colander and set aside until ready to use.
- After you’ve started the pasta water, begin making the cheese sauce. Start by melting butter in a large saucepan over medium heat. Once the butter has melted and is gently bubbling, add flour, mustard powder, freshly ground black pepper, and Kosher salt. Gently whisk to incorporate and smooth out any lumps.
- Continue whisking frequently until the roux turns a light blond color and emits a nutty aroma. Then, slowly stream in room temperature milk and continue to whisk over low heat until the mixture is smooth.
- Then, add the Guinness and continue whisking over low heat until the sauce is smooth and thickened, for about 5-7 minutes.
- Add five ounces each of shredded Kerrygold Dubliner and Kerrygold Aged Cheddar cheeses, a handful at a time.
- Whisk well after each addition, until all of the cheese has been added and the sauce is smooth.
- Once the sauce is finished, add the cooked pasta, three ounces of pastrami, and six slices of cooked and crumbled bacon to a large bowl. Stir everything to combine.
- Pour the cheese sauce into the bowl and stir to combine.
- Spray a 2-quart baking dish with non-stick cooking spray. Transfer the pasta mixture to the dish and spread it into an even layer.
- Top with remaining ounce of pastrami.
- Then, top with remaining four slices of crumbled bacon.
- Next, top with the remaining shredded Dubliner and aged cheddar cheese. Bake in a 375°F oven for 25-30 minutes, until cheese bubbles and is slightly golden.
- Remove from the oven and allow to cool for 5-10 minutes before serving. Serve with a garden salad and some Irish Guinness Brown Soda Bread.

Recipe Tips and Tricks
- Don’t boil the cheese sauce! High heat can cause the cheese to separate and become grainy. Keep the sauce at a gentle simmer over low heat.
- When purchasing the pastrami, ask for it to be shaved. Then, before using the pastrami, give it a quick chop with a large kitchen knife.
