Ingredients
1 tablespoon olive oil
Coarse salt and ground pepper
1 can whole tomatoes in puree (28 ounces)
1 large onion, cut into 8 wedges
1 tablespoon fresh rosemary, chopped (or 1 teaspoon dried and crumbled)
3 pounds beef chuck roast, trimmed and halved crosswise
4 garlic cloves, halved lengthwise
1 1/4 pounds small white potatoes, scrubbed
Preparation
With a sharp paring knife, cut 4 slits in beef roast; stuff slits with half the garlic. Generously season beef with 1 1/2 teaspoons salt and 1 teaspoon pepper. In a large skillet, heat oil over high heat, swirling to coat bottom of pan. Cook beef until browned on all sides, about 5 minutes.
In a 5-quart slow cooker, combine beef, onion, potatoes, tomatoes (with puree), rosemary, and remaining garlic. Cover; cook on high setting until meat is fork-tender, about 6 hours (do not uncover while cooking).
Transfer meat to a cutting board; thinly slice, and discard any gristle. Skim fat from top of sauce. To serve, divide beef and vegetables among bowls; generously spoon sauce over top.
