Irish Roast Beast: A Comforting Guinness-Infused Delight

There’s a certain magic that happens when the aroma of slow-cooked meat and rich, dark stout fills the kitchen. It reminds me of cozy evenings spent with family, the kind where laughter echoes and the simple act of sharing a meal feels like a grand occasion. I vividly recall my first encounter with this “Irish Roast Beast” on a blustery St. Patrick’s Day. The name alone, plucked from the pages of a cozy mystery, sparked immediate curiosity. That first bite, tender and imbued with the deep, malty essence of Guinness, was a revelation. It was more than just a pot roast; it was an invitation to a warmth and tradition that has since become a staple in my culinary repertoire.

• ½ teaspoon ground black pepper
• 4-5 lbs boneless chuck roast or 4-5 lbs rump roast
• 1 (¾ ounce) packet beef gravy mix

Equipment Needed

To bring this delicious dish to life, you’ll need a few essential kitchen tools:

• A large bowl for mixing the sauce ingredients.
• A slow cooker (4 to 6 quart capacity) OR a roasting pan with a tight-fitting lid or heavy-duty aluminum foil.
• A fork for testing the tenderness of the meat.
• A platter for serving the cooked meat.
• Aluminum foil for covering the meat to keep it warm.
• A saucepan for thickening the sauce (if using the oven method).

Instructions

The beauty of this recipe lies in its versatility. Whether you prefer the set-it-and-forget-it convenience of a slow cooker or the classic approach of oven roasting, the results are consistently impressive.

For the Slow Cooker Method:

1. Begin by preparing your slow cooker. Lightly spray the inside of a 4 to 6 quart slow cooker with non-stick cooking spray.
2. In a large bowl, combine the whole berry cranberry sauce, tomato sauce, Guinness stout, crumbled dried rosemary, ground thyme, sage, dried basil, salt, and ground black pepper. Stir everything together until well combined.
3. Pour about half a cup of this prepared sauce mixture into the bottom of the slow cooker insert.
4. Carefully place the boneless chuck roast or rump roast into the slow cooker, nestling it into the sauce.
5. Pour the remaining sauce mixture evenly over the top of the meat, ensuring it’s well coated.
6. Cover the slow cooker and cook on the low setting for 8 to 10 hours. Alternatively, if you’re running short on time, you can cook on the high setting for 6 to 7 hours. The roast is ready when it is easily pierced with a fork.
7. Once the meat is tender, remove it from the sauce and cut it into generous chunks. Place the meat chunks onto a platter and cover the platter loosely with foil to keep it warm while you finish the sauce.
8. Now, for the glorious sauce. Turn the slow cooker to the high setting. Sprinkle in the entire packet of beef gravy mix directly into the liquid in the slow cooker.
9. Stir the gravy mix into the sauce continuously until the sauce has thickened to your desired consistency.
10. To serve, drizzle a generous amount of the thickened sauce over the meat chunks on the platter. Pour the remaining sauce into a gravy boat or a small pitcher to be passed around the table.

For the Oven Method:

1. Preheat your oven to 325 degrees Fahrenheit. Ensure an oven rack is positioned in the middle of the oven.
2. Spray the inside of your roasting pan with non-stick cooking spray.
3. In a large bowl, combine the whole berry cranberry sauce, tomato sauce, Guinness stout, crumbled dried rosemary, ground thyme, sage, dried basil, salt, and ground black pepper. Stir everything together until well combined.
4. Place the boneless chuck roast or rump roast into the prepared roasting pan.
5. Pour the prepared sauce mixture evenly over the top of the meat.
6. Cover the roasting pan tightly with heavy-duty aluminum foil.
7. Bake in the preheated oven for 5 to 6 hours, or until the meat is easily pierced with a fork.
8. Once the meat is tender, remove the foil. Return the uncovered pan to the oven and let the roast brown for an additional 45 minutes.
9. Carefully remove the meat from the sauce and cut it into chunks. Place the meat chunks onto a platter and cover loosely with foil to keep it warm.
10. Pour the cooking sauce from the roasting pan into a saucepan.
11. Sprinkle the packet of beef gravy mix into the sauce in the saucepan. Thicken the sauce over medium heat, stirring constantly, until it reaches your desired consistency.
12. To serve, drizzle some of the thickened sauce over the meat on the platter. Put the rest of the sauce in a gravy boat or small pitcher for the table.

Expert Tips & Tricks

• Meat Selection: Both boneless chuck roast and rump roast work beautifully. Chuck roast tends to be more marbled, leading to exceptional tenderness, while rump roast offers a slightly leaner option.
• Guinness Substitute: While Guinness is the star, if you can’t find it, a good quality dark stout or porter will work in a pinch. The flavor will be slightly different but still delicious.
• Sauce Consistency: If your sauce isn’t thickening to your liking in either method, you can create a slurry with a tablespoon of cornstarch and a few tablespoons of water, then whisk it into the simmering sauce until thickened.
• Herb Power: Feel free to adjust the dried herbs to your preference. Fresh rosemary, thyme, sage, and basil can also be used, but you’ll want to use about three times the amount of fresh herbs compared to dried.
• Make Ahead: The sauce can be made a day in advance and stored in the refrigerator. Gently reheat it before adding it to the slow cooker or roasting pan. The meat can also be slow-cooked or roasted ahead of time and then gently reheated.

Serving & Storage Suggestions

This “Irish Roast Beast” is a true centerpiece. Serve it piping hot, generously drizzled with its rich, glossy sauce. It pairs exceptionally well with creamy mashed potatoes to soak up every last drop of that flavorful gravy and a side of roasted carrots for a touch of sweetness and color. For an authentic Irish touch, don’t forget your favorite “Irish soda bread” alongside!

Storage: Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. The meat and sauce can be stored together or separately.

Reheating: To reheat, gently warm the meat and sauce in a saucepan over low heat, or in the microwave at 50% power, stirring occasionally until heated through. Be careful not to overcook the meat, as it can become tough.
