Ingredients
Equipment
Method
- Pat the beef chuck roast dry with paper towels.
- In a large skillet, heat the olive oil over medium-high heat.
- Season the beef with salt, pepper, garlic powder, and onion powder.
- Sear the beef on all sides until nicely browned, about 3-4 minutes per side.
- Transfer the seared beef to your slow cooker.
- In the same skillet, add the sliced onions and minced garlic.
- Cook over medium heat, stirring occasionally, until the onions are softened and caramelized, about 15-20 minutes.
- Pour the caramelized onions and garlic over the beef in the slow cooker.
- Pour the beef broth, Worcestershire sauce, and balsamic vinegar over the beef and onions.
- Add the dried thyme and rosemary.
- Cover the slow cooker and cook on low for 8-10 hours, or on high for 4-5 hours. The beef should be incredibly tender and easily shreddable.
- Remove the beef from the slow cooker and shred it with two forks. Set aside.
- Skim off any excess fat from the surface of the gravy in the slow cooker.
- Turn the slow cooker to high.
- Whisk the cornstarch slurry (cornstarch and water) into the gravy.
- Cook, stirring occasionally, until the gravy has thickened to your desired consistency, about 5-10 minutes.
- Stir in the shredded beef and butter (if using).
- Season with salt and pepper to taste.
Notes
For a spicy kick, add a pinch of red pepper flakes or a diced jalapeño to the onion gravy. Sauté sliced mushrooms along with the onions for an earthy flavor boost. Add 1/2 cup of dry red wine to the slow cooker along with the beef broth for a richer flavor. Store leftovers in an airtight container in the refrigerator for up to 3-4 days. Reheat in a saucepan or microwave until heated through.
