5. Pour beef broth over the entire casserole.
Cover with aluminum foil.
6. Place the casserole dish in the preheated oven and bake for 1 hour, 15 minutes.
7. After removing from oven, sprinkle entire casserole with remaining 1/2 teaspoon coarse ground pepper.
Pro tip: Try adding shredded mozzarella cheese on top of the casserole (you can add it at the same time it goes in the oven) for a cheesy twist on this casserole!
Dig in and serve!
