How to Make French Onion Beef Au Jus

  1. Thinly slice 3 large yellow onions into 1/4-inch thick slices. Melt 4 tablespoons of butter in a large skillet over medium heat. Add onions and cook, stirring occasionally, until caramelized and golden brown (about 20-30 minutes).
  2. In a large bowl, whisk together 1/4 cup soy sauce, 1 packet onion soup mix, 2 cloves minced garlic, the caramelized onions, 1/4 cup strong brewed coffee, and 4 cups beef broth.
  3. Place a 3-4 pound beef roast (chuck roast or bottom round recommended) in a 4-quart oven-safe casserole dish or Dutch oven.
  4. Pour the soy sauce mixture over the roast, ensuring it's mostly submerged.
  5. Cover tightly and bake in a preheated 325°F (160°C) oven for 2 1/2 hours, or until the beef is fork-tender. Alternatively, slow cook on low for 8 hours (see step 13-16).
  6. Remove the roast from the oven and let it rest for 20 minutes before carving.
  7. Keep the cooking liquid (au jus) hot.
  8. Slice the roast thinly against the grain.
  9. Return the sliced beef to the au jus to keep it moist and flavorful.
  10. Slice French rolls lengthwise. Butter generously and toast in a 375°F (190°C) oven until golden brown. Slice a thin sliver off the bottom of each roll to create a flat surface.
  11. To assemble, place the hot beef slices and onions on the toasted bread. Sprinkle generously with 1 cup of shredded Gruyere or Swiss cheese.
  12. Broil in the oven until the cheese is melted and bubbly.
  13. **Slow Cooker Instructions:** Place the sliced onions in a 4 1/2 to 5 1/2 quart slow cooker. Top with the beef roast.
  14. In a separate bowl, whisk together 1/4 cup soy sauce, 2 cloves minced garlic, 1 packet onion soup mix, and 3 cups beef broth. (Omit butter).
  15. Pour the mixture over the roast in the slow cooker. Cook on high for 5 hours or low for 8 hours.
  16. Finish preparation as above (steps 6-12).
