How to Make Slow Cooker French Onion Chuck Roast
1. Season the Roast
Pat the chuck roast dry and season generously with salt and black pepper on all sides. This helps build flavor from the very start.
2. Sear for Depth (Optional but Worth It)
Heat butter or oil in a skillet over medium-high heat. Sear the roast on all sides until browned. This step adds richness to the final dish, but if you’re short on time, you can skip it.
3. Build the Onion Base
Spread the sliced onions evenly in the bottom of the slow cooker. Add the garlic on top.
4. Add the Roast and Liquids
Place the roast over the onions. Sprinkle the French onion soup mix evenly over the meat. Pour in the beef broth, Worcestershire sauce, and balsamic vinegar. Sprinkle with thyme.
5. Slow Cook
Cover and cook on LOW for 8–9 hours or HIGH for 4–5 hours, until the beef is fork-tender and easily shreds.
6. Finish and Serve
Once cooked, shred the roast directly in the slow cooker, stirring it into the onion-rich sauce. Taste and adjust seasoning if needed.
How to Serve It
This dish is incredibly versatile and pairs beautifully with:
Mashed potatoes or creamy polenta
Egg noodles or rice
Crusty bread for soaking up the sauce
Roasted vegetables or a simple green salad
For an extra French onion soup vibe, try topping servings with shredded Gruyère or Swiss cheese and broiling briefly until melted.
