07 - 1 cup beef broth

# How To Make It:

01 - Season the chuck roast generously on all sides with salt and pepper.
02 - Heat olive oil in a large skillet over medium-high heat. Sear the roast on all sides until deeply browned, approximately 3 to 4 minutes per side. Remove and set aside.
03 - In the same skillet, add onions and mushrooms if using. Sauté until onions are golden and beginning to caramelize, approximately 8 to 10 minutes. Add minced garlic and cook for 1 minute more.
04 - In a mixing bowl, whisk together beef broth, red wine or additional broth, Worcestershire sauce, soy sauce, thyme, and rosemary.
05 - Place the seared roast in the slow cooker. Top with the sautéed onions and mushrooms.
06 - Pour the broth mixture over the roast and onions.
07 - Cover and cook on LOW for 8 to 10 hours, until the roast is fork-tender.
08 - Remove the roast and let rest for 10 minutes. Slice or shred as desired.
09 - Place cheese slices over the meat in the slow cooker, cover, and let melt for approximately 5 minutes.
10 - Serve topped with onions, sauce, and melted cheese. Garnish with fresh parsley.

# Expert Insights:

01 -
  • The slow cooker does all the work while you go about your day, and you come home to a house that smells like a French bistro.
  • Chuck roast becomes so tender it shreds with just a fork, and the onions melt into the sauce in a way that feels almost magical.
  • Topping it with Gruyere at the end gives you that gooey, savory finish that makes everyone ask for seconds.
02 -
  • Don't skip the searing step, even if you're tempted to save time—it creates a crust that locks in flavor and adds a richness you can't get any other way.
  • If your sauce seems too thin at the end, mix 1 tablespoon cornstarch with 2 tablespoons cold water, stir it in, and cook on HIGH for 10 to 15 minutes until it thickens to a silky consistency.
03 -
  • Let the roast come to room temperature for 20 minutes before searing so it browns evenly and doesn't cool down the pan.
  • If you want an even richer sauce, stir in a tablespoon of butter at the very end—it adds a velvety finish that coats every bite.
