Ingredients
3–4 pound chuck roast
2 tablespoons olive oil
Salt and black pepper to taste
3 large yellow onions, thinly sliced
4 cloves garlic, minced
2 tablespoons butter
1 tablespoon Worcestershire sauce
1 tablespoon tomato paste
2 cups beef broth
1/2 cup dry white wine (or additional broth)
1 teaspoon fresh thyme (or 1/2 teaspoon dried)
1 bay leaf

Fresh parsley for garnish (optional)
Equipment
Large Dutch oven or heavy oven-safe pot

Step-by-Step Instructions
- Preheat oven
Preheat oven to 325°F. - Season and sear the roast
Pat the chuck roast dry and season generously with salt and pepper. Heat olive oil in a Dutch oven over medium-high heat and sear the roast for 3–4 minutes per side until deeply browned. Remove and set aside. - Caramelize the onions
Reduce heat to medium and add butter and sliced onions. Cook slowly for 15–20 minutes, stirring occasionally, until onions become deeply golden and caramelized. - Add garlic and flavor base
Stir in garlic and tomato paste, cooking for 1 minute until fragrant. Add Worcestershire sauce and scrape up browned bits from the pot. - Deglaze the pot
Pour in white wine (or broth) and simmer for 2–3 minutes to lift flavorful bits from the bottom. - Build the braising liquid
Add beef broth, thyme, and bay leaf. Stir gently to combine. - Braise the roast
Return the roast to the pot, nestling it into the onions. Cover with a lid and transfer to the oven. - Slow cook
Cook for 4–5 hours until the meat becomes fork-tender and easily pulls apart. - Thicken the gravy (optional)
If desired, mix flour with a little liquid to form a slurry and stir into the pot during the last 15 minutes of cooking. - Rest and serve
Remove bay leaf, shred or slice the roast, and spoon caramelized onion gravy over the top before serving.
