- measuring spoons

Ingredients
Beef and Vegetables
- 4 pound boneless beef chuck roast tied if loose
- 2 teaspoons kosher salt plus more to taste
- 1 teaspoon freshly ground black pepper
- 2 Tablespoons olive oil
- 1 Tablespoon unsalted butter
- 1 pound yellow or sweet onions halved and thinly sliced
- 8 ounces cremini or baby bella mushrooms halved
- 3 –4 medium carrots cut in big chunks (about 2")
- 2 ribs celery cut in big chunks
- 4 cloves garlic smashed
Braising liquid
- 1½ teaspoon fresh thyme leaves or ½ teaspoon dried thyme
- 2 bay leaves
- ½ cup dry red wine or dry sherry optional but lovely
- 3 cups low-sodium beef stock
- 1 teaspoon Worcestershire sauce optional booster
To serve
- 1 small baguette sliced and toasted
- 1½ cups grated Gruyère or Gruyère and a little Parmesan
Instructions
- Heat the oven to 300°F. Pat roast dry with paper towels and season all over with the salt and pepper.
- In a large Dutch oven, heat olive oil over medium-high heat until shimmering. Sear roast 4-5 minutes on each side until deeply browned and crusty. Transfer to a plate.
- Reduce heat to medium. Add butter and onions with a pinch of salt. Cook, stirring occasionally, until onions are deep golden brown (20-25 min). If fond begins to scorch, splash in a spoonful of water to loosen and scrape up with a wooden spoon.
- Stir in mushrooms, carrots, celery, and garlic; cook 3-4 min. Add thyme and bay leaf, cook 30 seconds longer.
- Pour in wine or sherry then simmer 2-3 min, scraping up browned bits on the bottom of the pan with a wooden spoon until mostly evaporated.
- Add beef stock and Worcestershire. Return roast (and any juices) to the pot, nestling it into the onions and vegetables. Liquid should come about halfway up the meat, add a bit more stock or water, if needed. Bring to a simmer, cover, and transfer to oven.
- Braise 3-3½ hours, turning the roast once or twice, until the roast is fork-tender.
- Using tongs, transfer roast to a platter or cutting board; tent with foil 10-15 minutes. Skim excess fat from the braising liquid and remove the bay leaves. Taste and season with kosher salt/black pepper to taste.
- Serve. Slice or shred the roast, nestle into the onion-mushroom gravy, and serve with cheesy toasts.
Notes
- Cut richness: Add 1 tsp Dijon or a squeeze of lemon at the end for brightness.
- Vegetable options: Swap parsnips or halved baby potatoes for the carrots/celery; add in the last 1½ hours so they don’t over-soften.
- Make-ahead: Tastes even better the next day. Chill overnight, lift the firm fat cap, rewarm gently.
- Slow cooker: After searing and caramelizing on the stove, transfer everything to a slow cooker; cook 8–9 hours on low (or 5–6 on high).
- Instant Pot: Sear on Sauté, caramelize onions, deglaze, then pressure cook 60–70 minutes on High with natural release 15 minutes. Broil the Gruyère toasts separately.
Long, slow onion caramelization, thyme and bay leaf, a beefy stock, and a small dose of wine/sherry replicate my French onion soup's savory backbone and bring that familiar, cozy depth to the roast and gravy.
