Slow cooked beef, onions, and cheese piled high on a soft bun dipped in a savoury au jus, what could be better? Beef dip is an easy crowd pleaser that definitely will not disappoint.
To prepare the beef roast: Pat the roast dry and generously season each side with salt and pepper. Using your hand, pat the seasoning into the beef.
In a heavy bottom pan or cast iron pan, heat 1 tablespoon of oil over medium-high heat and brown each side of the beef, about 2 to 3 minutes each side. (Note: You may need to add additional oil while browning each side to prevent burning). Coat the bottom of the slow cooker with some oil and transfer the roast to the slow cooker.
In the same pan, add another tablespoon of oil and cook the onions and garlic for about 5 minutes or until a golden colour develops over medium heat. Transfer the onions and garlic to the slow cooker when done. Add in beef broth, worcestershire sauce, pickled peperoncini peppers and liquid, and bay leaf to the slow cooker.
Set the slow cooker to low and cook for 6 to 7 hours. Turn the roast over halfway through cooking.
Carefully remove the roast and place on a cutting board. Thinly slice the roast. Skim off the fat from the roast juices and place the sliced roast back into the juices. Let the roast sit in the juices for about 30 minutes.
To prepare the beef juice: Strain the beef juice and serve in a dipping bowl.
To make the horseradish spread: Mix together horseradish, Dijon, mayonnaise, and parsley in a small bowl.
To prepare the sandwich: Set the oven to broil. Butter both halves of each of the buns and place on a baking sheet, cut side up. Toast for a few minutes or until golden brown.
Place meat, onions, and peppers on the bottom half of the bun and place 2 slices of Swiss cheese over the meat. Repeat for the remaining buns. Place the sandwich back on the baking sheet (without the top buns) and broil until the cheese melts, about 1 minute.
Spread the top buns with a generous amount of horseradish spread and top each of the bottom halves.
