- 1 teaspoon salt
- 1 teaspoon black pepper
- 1 teaspoon garlic powder
For the Caramelized Onions
- 4 large yellow onions, thinly sliced
- 2 tablespoons butter
- 1 tablespoon olive oil
- 1 teaspoon sugar (optional)
For the Gravy
- 3 cups beef broth
- 1 tablespoon Worcestershire sauce
- 2 cloves garlic, minced
- 1 teaspoon dried thyme
- 1 bay leaf
- 2 tablespoons cornstarch
- 3 tablespoons cold water
Step-by-Step Directions
Step 1: Season the Beef
Pat the roast dry with paper towels.
Season all sides with salt, pepper, and garlic powder.
Step 2: Sear the Roast
Heat olive oil in a large Dutch oven or skillet over medium-high heat.
Sear the roast for 3 to 4 minutes per side until a deep golden-brown crust forms.
Remove and set aside.
Step 3: Caramelize the Onions
Reduce heat to medium.
Add butter and olive oil to the pot.
Add the sliced onions and cook slowly for 25 to 30 minutes, stirring occasionally, until deeply golden and caramelized.
If desired, sprinkle with sugar to enhance caramelization.
Step 4: Build the Flavor Base
Add minced garlic and cook for 1 minute.
Pour in a small amount of beef broth and scrape up any browned bits from the bottom of the pot.
Step 5: Slow Cook the Roast
Return the roast to the pot.
Add the remaining beef broth, Worcestershire sauce, thyme, and bay leaf.
Cover and cook:
- Oven Method: 325°F (163°C) for 3 to 4 hours
- Slow Cooker: Low for 8 to 9 hours
The beef should be fork-tender when done.
Step 6: Prepare the Gravy
Remove the roast and keep warm.
Discard the bay leaf.
Mix cornstarch and cold water until smooth.
Slowly whisk the slurry into the cooking liquid.
Simmer for 3 to 5 minutes until the gravy thickens.
Step 7: Serve
Slice or shred the beef.
Spoon the rich caramelized onion gravy generously over the roast.
Serve hot.

Tips for Success
- Chuck roast provides the best flavor and tenderness for slow cooking.
