Preparation

Step 1

In a large Dutch oven, heat olive oil over medium-high heat. Sprinkle roast with salt and pepper. Brown roast, in batches, for 3 to 4 minutes per side; remove from pan, and set aside.
In the same Dutch oven, melt butter over medium heat. Add onions, and cook, stirring frequently, for 15 to 20 minutes, or until onions are tender. Increase heat to medium-high, and cook for 3 to 4 minutes, stirring frequently, or until onions are caramel colored. Stir in garlic and flour, and cook, stirring constantly, for 2 minutes. Add roast, consomme, broth, Worcestershire, bay leaves, and thyme. Simmer, stirring occasionally, uncovered, for 1 hour. Stir in cream, and simmer, uncovered, for 30 minutes. Discard bay leaves.
Preheat broiler. Lightly grease a 13x9-inch baking dish.
Spoon roast mixture into prepared baking dish. Place toasted French bread slices evenly over roast. Sprinkle with cheese. Broil, 5 inches from heat, for 3 to 4 minutes, or until cheese is melted. Garnish with fresh thyme, if desired. Serve immediately.
