These Slow Cooker French Dip Sandwiches are so good if you can find a good whole-wheat baguette, but worth making no matter what bread you use. Make sure to use a dark beer like Guinness to really make these delicious.
Place the roast in the bottom of the slow cooker. Mix together the spices in a small bowl and rub all over the meat.
Pour in the beer and broth, and cook on low until the meat can easily be shredded with a fork, 8 to 10 hours. (Be sure to retain some of the cooking juices for the au jus.)
When you're ready to serve, preheat the oven to 450 degrees F. Cut the baguettes into quarters, split open the pieces, spread with a thin layer of butter, and sprinkle lightly with garlic powder.
Divide up the shredded meat and pile it onto half of the bread pieces. Top the meat with folded over slices of provolone cheese, place all bread (both with and without meat) on a baking sheet, and bake until the cheese melts, 3 to 5 minutes.
Serve warm with a side of au jus (cooking liquid in the slow cooker) that's been seasoned with a little salt and pepper.
