Trim and cut 3 1/2 lbs boneless beef chuck roast into 2-inch chunks. Season generously with 1 1/2 tsp kosher salt and 1 tsp freshly ground black pepper. Heat 2 tbsp olive oil in a large Dutch oven over medium-high heat. Sear beef until browned on all sides, then remove. This is the first step for your French Onion Pot Roast (Slow Cooker or Dutch Oven).

In the same Dutch oven, add 4 large yellow onions, thinly sliced. Cook over medium heat for 10-15 minutes until softened and lightly caramelized. Add 6 cloves garlic, minced, and cook for another minute until fragrant.
03 -
Pour in 1 1/2 cups dry red wine, scraping up any browned bits from the bottom of the pot. Add 4 cups low sodium beef broth, 2 tbsp Worcestershire sauce, 1 tbsp Dijon mustard, 4 sprigs fresh thyme, and 2 bay leaves. Bring to a simmer, creating the flavorful base for your French Onion Pot Roast (Slow Cooker or Dutch Oven).
04 -
Return the seared beef to the Dutch oven, or transfer everything to a 6-quart slow cooker. Cover tightly. If using a Dutch oven, bake at 300°F for 6-7 hours. If using a slow cooker, cook on low for 8-10 hours or high for 4-5 hours, until the beef is fork-tender.
05 -
Remove the beef from the pot and shred it using two forks. Discard the thyme sprigs and bay leaves. If desired, skim any excess fat from the sauce. For a thicker sauce, simmer uncovered on the stovetop for 10-15 minutes, allowing the flavors to concentrate.
06 -
Return the shredded beef to the sauce. Ladle the French Onion Pot Roast (Slow Cooker or Dutch Oven) into bowls. Top each serving with a generous sprinkle of 6 oz shredded Gruyere cheese. Broil briefly until melted and bubbly, then garnish with 1/4 cup fresh parsley, chopped.
