Ingredients
  

  • 3-4 pound chuck roast
  • 2 tablespoons olive oil
  • 2 large yellow onions, thinly sliced
  • 4 cloves garlic, minced
  • 1 teaspoon dried thyme
  • 1/2 teaspoon dried rosemary
  • 1/4 cup all-purpose flour
  • 4 cups beef broth
  • 1 cup dry red wine optional
  • 2 tablespoons Worcestershire sauce
  • 1 bay leaf
  • Salt to taste
  • Pepper to taste
  • Baguette slices, toasted
  • 2 cups grated Gruyere cheese
  • Fresh parsley optional, for garnish

Equipment

  • Dutch oven or oven-safe pot with lid
  • measuring cups and spoons
  • cutting board
  • knife
  • paper towels
  • fork
  • Broiler

Method
 

  1. Pat the chuck roast dry with paper towels. Season generously with salt and pepper.
  2. Heat the olive oil in a large Dutch oven or oven-safe pot over medium-high heat.
  3. Sear the roast on all sides until browned, about 3-4 minutes per side. Remove the roast from the pot and set aside.
  4. Add the sliced onions to the pot and cook over medium heat, stirring occasionally, until deeply caramelized and golden brown, about 20-30 minutes. If the onions start to stick, add a splash of beef broth.
  5. Add the minced garlic, thyme, and rosemary and cook for another minute until fragrant.
  6. Stir in the flour and cook for 1 minute to create a roux.
  7. Pour in the red wine (if using) and scrape the bottom of the pot to deglaze. Let the wine reduce slightly, about 2-3 minutes.
  8. Add the beef broth and Worcestershire sauce. Bring to a simmer.
  9. Return the roast to the pot and add the bay leaf. The liquid should almost cover the roast; add more broth if needed.
  10. Cover the pot tightly and transfer it to a preheated oven at 325°F (160°C).
  11. Braise for 3-4 hours, or until the roast is fork-tender. Check for tenderness after 3 hours.
  12. Remove the pot from the oven. Carefully remove the roast from the pot and shred it with two forks.
  13. Skim any excess fat from the surface of the sauce.
  14. Return the shredded beef to the pot and stir to combine with the sauce.
  15. Preheat your broiler to high.
  16. Arrange the toasted baguette slices on top of the beef mixture in the pot.
  17. Pile the grated Gruyere cheese on top of the baguette slices.
  18. Broil for 2-3 minutes, or until the cheese is melted and bubbly. Watch it carefully to prevent burning!
  19. Let the French Onion Pot Roast cool slightly before serving. Garnish with fresh parsley, if desired.
  20. Serve hot and enjoy!

Notes

For a richer flavor, use bone-in chuck roast. You can add vegetables like carrots, potatoes, and celery halfway through the cooking time. To thicken the sauce, simmer it over medium heat or whisk in a cornstarch slurry (1 tablespoon cornstarch + 2 tablespoons cold water). If you don't have Gruyere cheese, you can substitute Swiss, Provolone, or Monterey Jack. The pot roast can also be made in a slow cooker on low for 6-8 hours or on high for 3-4 hours after searing and caramelizing the onions.
