Slow Cooker French Onion Pot Roast
Ingredients
3 lb (1.4 kg) beef chuck roast
2 tbsp olive oil
2 large yellow onions, thinly sliced
4 garlic cloves, minced
2 cups beef broth
1 tbsp Worcestershire sauce
1 tbsp soy sauce
1 tsp dried thyme
1 tsp rosemary
1 tsp black pepper
1 tsp salt
1 tbsp cornstarch (optional, to thicken)
2 tbsp cold water (optional)
Instructions
Pat the beef roast dry with paper towels and season generously with salt and black pepper on all sides.
Heat the olive oil in a large skillet over medium-high heat. Sear the roast for 3β4 minutes per side until deeply browned.
In the same skillet, add the sliced onions and cook for 10β15 minutes, stirring often, until caramelized. Add the minced garlic and cook for 1 minute.
Transfer the caramelized onions to the slow cooker and place the seared roast on top.
Pour in the beef broth, Worcestershire sauce, and soy sauce. Sprinkle with thyme and rosemary.
Cover and cook on LOW for 8β9 hours or HIGH for 4β5 hours, until the beef is fork-tender.
Remove the roast and keep it warm. If you prefer a thicker gravy, whisk together the cornstarch and cold water, then stir it into the cooking liquid. Cook on HIGH for 10β15 minutes until the sauce thickens.
Slice or shred the beef and return it to the rich onion gravy.
Serve hot with mashed potatoes, buttered noodles, or crusty bread, and spoon plenty of the savory onion sauce over the top.
