Gather these essentials to create a comforting French Onion Pot Roast
INGREDIENTS
- – 3-4 lb beef chuck roast
 - – 2 large yellow onions, thinly sliced
 - – 4 cups beef broth (low-sodium recommended)
 - – 2 tbsp unsalted butter
 - – 1 tbsp olive oil
 - – 2 cloves garlic, minced
 - – 1 tbsp Worcestershire sauce
 - – 1 tsp dried thyme
 - – 1 tsp onion powder
 - – 1/2 tsp black pepper
 - – 1/2 tsp salt (adjust to taste)
 - – 2 tbsp cornstarch (optional, for thickening)
 - – 2 tbsp water (optional, for slurry)
 
PREPARATION
- Start by patting the chuck roast dry with paper towels. Season it generously with salt and black pepper on all sides for optimal flavor.
 - In a large skillet, heat 1 tbsp olive oil and 2 tbsp butter over medium-high heat. Sear the roast for about 3-4 minutes per side until a golden-brown crust forms. This step locks in juices and enhances the taste.
 - Transfer the seared roast to your crock pot slow cooker. Arrange the thinly sliced onions around and on top of the meat.
 - In a bowl, whisk together 4 cups beef broth, minced garlic, Worcestershire sauce, thyme, and onion powder. Pour this mixture over the roast and onions in the crockpot.
 - Cover and cook on low for 8 hours or high for 4-5 hours, until the beef is fork-tender and easily shreds.
 - (Optional) If you prefer a thicker au jus for dipping (perfect for french dip sandwich crockpot style), mix 2 tbsp cornstarch with 2 tbsp water to create a slurry. Stir it into the crockpot juices during the last 30 minutes of cooking on high.
 - Once cooked, shred the beef with two forks directly in the crockpot, allowing it to soak up the flavorful broth. Serve hot as is or pile it onto rolls for crockpot beef sandwiches with a side of au jus for dipping.

Why Use a Chuck Roast for This Recipe?
The chuck roast is ideal for slow cooker roast recipes like this French Onion Pot Roast due to its high fat content and connective tissue, which break down during long cooking times, resulting in tender, juicy meat. Unlike leaner cuts, it holds up well to crock pot cooking without drying out.
How to Achieve Perfectly Caramelized Onions in a Crockpot?
While the onions won’t caramelize in the traditional sense without high heat, layering them around the roast and cooking them in broth for hours mimics the process. For deeper flavor, you can sauté them in the skillet after searing the meat for 5-7 minutes before adding them to the crockpot.
Can You Turn This Into a French Dip Sandwich?
Absolutely! This recipe doubles as a fantastic base for a french dip sandwich crockpot creation. Simply shred the beef, pile it onto crusty rolls, top with melted provolone or Swiss cheese, and serve with a small bowl of the au jus from the crockpot for dipping.
What Sides Pair Best with French Onion Pot Roast?
Complement this hearty dish with mashed potatoes, roasted vegetables, or a simple green salad. If you’re making crockpot beef sandwiches, a side of crispy fries or coleslaw ties the meal together beautifully.
How to Store and Reheat Leftovers?
Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat on the stovetop over low heat with a splash of broth to keep the meat moist, or use the microwave in 30-second intervals, stirring in between.
Can You Freeze French Onion Pot Roast?
Yes, this dish freezes wonderfully. Place cooled beef and broth in a freezer-safe container or bag for up to 3 months. Thaw overnight in the fridge before reheating, making it a great option among crockpot recipes easy to prep ahead.
FREQUENTLY ASKED QUESTIONS
Can I use a different cut of beef for this recipe?
While chuck roast is recommended for its tenderness after crock pot slow cooker time, you can substitute with bottom round or brisket. Keep in mind that leaner cuts may require extra broth or shorter cooking times to avoid toughness in your French Onion Pot Roast.
How do I prevent the broth from being too salty?
Opt for low-sodium beef broth and adjust seasoning at the end of cooking. Taste the au jus before serving, especially if you plan to use it for dipping in french dip crock pot sandwiches, and dilute with water if needed.
Can I add vegetables to the crockpot?
Yes, root vegetables like carrots or potatoes can be added during the last 2-3 hours of cooking on low. This keeps them from becoming mushy while infusing them with the rich flavors of your slow cooker roast.
